About this episode’s guest: Tucker Perkins

Tucker is the president and chief executive officer of the Propane Education & Research Council (PERC), and his vision for the future is best explained by his own podcast’s title: “Path to Zero.” A firm believer that climate change is real and man-made,Tucker advocates for all energy solutions that will create a cleaner and healthier environment today and into the future. 

Zero emissions is a goal we can all get behind,but how do we meet the world’s growing energy demands AND reduce carbon in the atmosphere? Tucker believes the best and most realistic wayforward is a wide path that incorporates renewables and clean liquid fuels, such as propane, to accelerate decarbonization and reach our climate goals as soon as possible.

Tucker’s insights and theories are backed by his 30+ years of work in the propane industry. He operated his own propane retail company, Premier Propane, and has held executive positions at Columbia Propane, CleanFuel USA and Inergy Propane. Tucker is active with many industry organizations, including the National Propane Gas Association, World LP Gas Association, Industrial TruckAssociation and Outdoor Power Equipment Institute.

Gene Tunny  00:06

Welcome to the Economics Explored podcast, a frank and fearless exploration of important economic issues. I’m your host Gene Tunny. I’m a professional economist and former Australian Treasury official. The aim of this show is to help you better understand the big economic issues affecting all our lives. We do this by considering the theory evidence and by hearing a wide range of views. I’m delighted that you can join me for this episode, please check out the show notes for relevant information. Now on to the show. Hello, thanks for tuning in to the show. In this episode, I chat with Tucker Perkins about the energy transformation that we’re going through. Tucker is head of the Propane Education and Research Council perk, and he’s the host of the path to zero podcast. In our conversation, Tucker argues strongly for renewable propane, and for other sustainable liquid fuels being an important part of the energy mix in the future. According to perc, the most common form of renewable propane today is a byproduct of renewable diesel and sustainable aviation fuel made primarily from plant and vegetable oils, animal fats or used cooking oil. Stay tuned to also hear Tucker’s thoughts on how the energy transformation is going, and whether we should consider nuclear energy in the transition to net zero. If you have any thoughts on what Tucker I have to say in this episode, then please let me know. You can email me via contact at economics explore.com. Okay, let’s get into the episode. I hope you enjoy my conversation with Tucker Perkins. Tucker perkins, welcome to the programme.

Tucker Perkins  01:53

I’m going to enjoy being with you today. Thanks so much for having me.

Gene Tunny  01:57

Oh, of course, Tucker. Yes. Lots to talk about, given that your background and your position. So you’re the president and chief executive officer of the propane Education and Research Council P. C? Or is it perk, PRC or perk,

Tucker Perkins  02:17

we’ll call it perk for the rest of this talk. So

Gene Tunny  02:19

very good. Could you tell us a bit about your journey to perk, please Tucker? How did you end up becoming the president of what what what’s your you’ve got a background in the industry?

Tucker Perkins  02:32

Obviously, it’s you know, as I reflect on it backwards, you know, it’s been the culmination of kind of everything I did up to this point. But let’s start at the beginning. Like so many people that so in the US, we’ll call it propane, but the rest of the world and Australia included you gonna call it LPG, right. But you grew up in a into a household or my father ran a propane company that was a fairly good sized regional company. So I’d watch him go to work and saw what he did and seem to have a good living and enjoy his work. So always something I did in the summers as I was growing up, went off to college and was an engineer, and didn’t want to work for my dad at a college. I wanted to do something else. He was the president. And I didn’t really want to be the son of the President. So I worked I was a consulting engineer doing today. Now when I look back on is really relevant work, land use planning, water conservation. You’re really thinking about how urban areas should evolve walkable cities, livable places. And now it’s really to me forefront of so much we do is around conservation, right? Conservation of energy, conservation of water, how could we drive less, I mean, things that are really relevant. So I did that for a while but pretty quickly was recruited to go to work in the natural gas industry. He’s kind of a, an engineer on a pipeline, designing pipelines, building pipelines, operating them. We then built and operated in a liquefied natural gas facility, actually operated facility that turned butane or propane into natural gas. So really got great exposure in the natural gas business from drilling through the golf or Appalachian mountains, and to cleaning it up and then transporting and ultimately putting it on to ships if that’s what it took for LNG, so great, great support. But eventually, I wanted to do something I was a bit more entrepreneurial, and found my way back into the propane business, and ultimately worked my way to be the chief operating officer of the fourth largest propane company in the country. We then sold that and I started myself the smallest propane company in the country. Just me then me and a driver than me a driver and a service person. Then we added and I grew that business up and then we sold it in to a larger public company where I worked with them, so really ever had such great experiences in natural gas, natural gas liquids, you know, multinational work, you know, smallest company in the world. And ultimately, I went in and was a manufacturer for a while we were actually manufacturing propane systems. And at the conclusion of that, a job came up at the propane Education and Research Council to be in charge of all the business development. And I took that job, and then not long after that became CEO, oh, and not long after that became CEO. So it’s been a great, it’s just a great transition. And now really, just the last couple of years, you know, we’ve really started talking about how do low carbon fuels like natural gas and propane or LPG? How do they fit into this energy transformation that we talk about routinely? So having an engineering background being real familiar with natural gas, LNG, LPG really helpful to kind of set up for this last phase of my career?

Gene Tunny  06:11

Yeah, yeah, very good. Okay. So we’ll get on to that energy transformation in a moment, I’ll I should know that you’ve got your own podcast path to zero, which is great. So we’ll talk a bit about that later. Before we get on to that, I just like to ask a bit more about perk. This is an is IT industry funded Tucker it what’s the mission of the perk?

Tucker Perkins  06:35

Broadly, a perk is industry funded, we take a small percentage from every gallon sold in the US. So we have a very us focus. But again, the technologies we’re developing, we really encourage him to be used worldwide. I mean, it’s, it’s good for everyone. To see this technology is expanded way beyond the US. But we’re funded and our funding comes into about $50 million a year. And then we take that money and deploy it really one of three ways. First is around safety and training and safety and training for the industry. For the consumers of propane, we want to make sure that our industry and those people who touch propane, use propane, understand how to use it safely, that it’s installed safely in accordance with the codes. And we really, I’m so proud of where we have come over the last five or six years in digital training, helping helping you whether you want to work for a propane company and become a driver or service tech or even a customer representative. Or whether you’re filling cylinders at the local filling plant, or you’re a consumer and you need to know what to do when you smell the odour of gas. So safety and training, top of mind, a lot of marketing and awareness, you know, just talking about the value of propane, renewable propane as a part of the energy mix. And then the last piece of that really has been technology development to embed in the different markets agriculture, transportation, power generation, residential commercial, to embed into those markets, and see where the gaps are, and to see how LPG can fill those gaps. And it’s been amazing. I mean, I know I talked with you earlier. And, you know, 15 years ago as as a world body, we saw that ship fueling was dirty, filthy. In fact, it from a mission standpoint, inexpensive, powerful, but filthy. And we realised that propane offered a much better way to fuel his ship. today. We’ve had a monumental movement in using propane aboard ships, something that has been adopted way greater pace than I thought. But you know, we work with farmers every day about how to use propane today not only to dry green, or perhaps propel their tractor, but how to use it for flame techniques so they could become more gain. It can use less herbicides, pesticides, we work with builders, we’ve got some innovative products coming out that generate power and heat. And maybe our most exciting programme right now is with Cummins and a programme that I hope you see in Australia soon. Really the crazy powerful 6.7 litre propane purpose engine that can power medium duty trucks and do it in a way that’s probably more cost effective than any other option. And we cut greenhouse gases 25% from the next best technology on the market today. So you know, just actually literally putting our money where our mouth is and bringing innovative products to the marketplace that actually make consumers comfortable. Give them an affordable energy source yet do great things for the environment. Hmm,

Gene Tunny  10:06

right. Yeah. Okay, there’s few things I want to follow up there. First, just for, I just want to make sure I understand. So LPG or propane. Where would most people be coming into contact with that now? Would that be it when they’re doing they have that having a barbecue, they get the, the cylinder for their barbecue? Would that be one of the uses?

Tucker Perkins  10:28

Well, everyone comes into contact with it, they’re when they’re having their barbecues. Hopefully, we’ve all moved past charcoal now but So yeah, that’s where that’s where the typical consumer, but you know, a farmer touches it every day in December anyways, animal heat, green drying. We see it in in the US. We are fairly dominant in residential heating, hot water cooking, clothes drying, same for commercial segment. And then in transportation, and few people realise, but we’re really the third most widely used fuel in the world for transportation beyond diesel and gasoline. The next the next most widely use fuel is propane, or LPG.

Gene Tunny  11:14

Yeah, I know a lot of taxis here. have used it in Australia. So yeah, absolutely. Okay. And what about with, you’re talking about shipping? So what type of ships are we talking about? And what is it replacing? Is it replacing diesel? What’s what’s going on there?

Tucker Perkins  11:34

Yeah, well, or generally replacing even the next dirtier version of diesel first, so bunker fuel. So that heavy, that Heavy Diesel that ships used, where it will again, it was inexpensive, it’s powerful. But, you know, when you look at the emissions profile, intensely Laden was particulate matter, co2, NOx emissions, nothing that we really want to be spewing into the air, and rightfully the international community, you know, said we, there’s got to be a better way, we’ve got to fuel our ships, because again, here’s an area where ships use, you know, gargantuan volumes of fuel on an annual basis, right. So that’s an area where cleaning up the emissions truly makes a difference in our environmental footprint. So the other movie, these ships are moving from bunker fuel or diesel, to generally either natural gas, propane. You read some about ammonia, or methanol, or those kind of the, those are the four fuels that are in play right now for a ship of the future.

Gene Tunny  12:44

Right. So what types of ships are we talking about cargo ships, ocean liners, what about the oil tankers? What sort of sort of ships are we talking about? So most

Tucker Perkins  12:54

of our ships are currently carrying LPG. So those would be LPG carriers. And they could be vlg seas, very large gas carriers. But, you know, propane has moved so much around the world. And though that’s the first choice, because they already had their vessel full of propane, and so it’s relatively easy for them to to migrate to propane engines. But it certainly won’t stop there. We’re seeing some cargo ships there. I do think the probably the last in the line will be cruise ships. But we see some cruise ships now moving to liquefied natural gas. And so it’s only a matter of time. I think before all styles of ships. One style we really are interested in something very prominent in actually Australia would be ferries work boats, tugboats, fishing boats. If you go to Chile today, a lot of the fishing vessels in Chile are powered by LPG much cleaner, much easier to store for them, and much less expensive. And so for a fisherman, they actually could twofold right? They cut their costs and improve their emissions. So, you know, depends on a little bit where you go in the world to see how it’s being used. But it’s so versatile. It’s highly used in engines,

Gene Tunny  14:17

Rod, okay, and so how does it compare? What’s the right terminology pound for pound or I’m just trying to think so You mentioned a 6.7 litre propane engine for the for trucks. If I fill up the truck, will I get a similar range? If I’ve compared with if I build it with diesel? Do I get the similar amount of power? How does it compare?

Tucker Perkins  14:42

So the energy content of a gallon of propane is about I don’t know three quarters of the energy content of a gallon of diesel. Right but fuel managers tend to think about things in terms of cost per mile. Yeah, or opera. Reading cost per mile. And it’s shocking to me where we are, we’ve always been cheaper than. But now we are significantly cheaper than in fact, in most in most. And I probably have looked at 100 or 200. Operating statistics over the last month or two, we’re always half of the cost of diesel or more, in a diesel right now has been fairly elevated in price, propane has been fairly depressed in price. So it’s not unusual for us to see 60 70% savings in a cost per mile, moving from diesel to propane. And that’s really, you know, that’s important in a medium duty truck. Right, medium duty trucks are our breadbasket. They’re delivering goods and services to us, and to be able to cut their costs by 60, or 70%. While we cut their emissions, while we quiet the engine, it’s monumental benefit to the driver, to every community they serve, and ultimately to the people who are paying for those goods and services they deliver. So massive benefit.

Gene Tunny  16:08

Yeah, is there any difference in the frequency at which you have to fill

Tucker Perkins  16:11

up now, you as a designer of those engines, we, we almost always make sure that we have the same range. So your diesel truck had 600 miles of range, then we make sure you have 600 miles of range, you know, we found is this conversation goes around electric vehicles and, you know, we, we really highlight, you know, that you probably have to change to drive an electric vehicle, certainly a medium duty electric truck, you’re going to change something you’re gonna it takes you longer to refuel, you won’t be able to go as far, you know, we just don’t find commercial businesses are really able to do that they need, they need to demonstrate significantly better than before they’ll leave diesel or gasoline. And I think with propane, we demonstrate significantly better than cheaper, more powerful, frankly, quieter, and much better emissions.

Gene Tunny  17:08

Okay, we’ll take a short break here for a word from our sponsor.

Gene Tunny  17:43

Now back to the show. Right Oh, so you mentioned before about the role of gas, so propane and other and other gases in this transition in the energy transformation. So as we head toward Net Zero, how do you see that broadly Tucker? What’s the what’s the role? Is it just as transition field as we move toward more lower carbon sources? Is there a permanent role for gas? How do you see that their role in that energy transformation?

Tucker Perkins  18:21

You know, probably I probably answered your question, in a funny way. Because when we started, certainly we thought this, that gas would be a transition. But as as we really studied, where we believe hydrogen goes, maybe we’re wind and solar goes. And wind and solar are going to be completely captivated by how fast we get the battery storage and energy storage, right? We we really cannot have appropriate wind and solar without being able to store that intermittent supply that really relevant relates as well to Evie vehicles, right? It really gets to about can we make a light enough battery that charges fast enough that holds that energy that lets us have four or 500 miles of range? How long does it take for the engineers to come to those answers? And by the way, as a technologist, I certainly believe we come to those answers, right. But I think what’s interesting to me, as we really think, again, I keep the goal in mind. The goal in mind is to reduce carbon. And we can fool ourselves by saying I drive a zero emission vehicle. But the only time that vehicle is truly a zero emission is when it’s at rest, right? The minute we have to charge it and we have to really think about that system. What I’m excited this A is as we really studied both renewable natural gas and renewable propane. We find that even under the most optimistic scenarios that we can craft for electricity, there will always be a benefit to using a powerful liquid Fuel, like renewable propane or renewable propane blend in an efficient engine. And perhaps gene engine might be a hybrid engine me, that vehicle may be the best of electric drive and internal combustion drive. But I really pivoted my answer to say, No, I think there will always be a place for low carbon and renewable fuels. And the last piece is about this is economics, because we don’t really want to, you know, openly address the cost of this transition. But in the US, we talk openly about 3 trillion, I’ve talked openly on a worldwide basis that it probably looks to me more like 30 or $40 trillion. And a few outside banking agencies have kind of verified that number. Now. That’s a lot of money. And we have to think about, I think often about, are we deploying those dollars in the right place and a world where we need better medicine, better schools, better highways and bridges? can we really afford to spend that kind of money when we have some of these clean solutions right in front of us. And that’s a conversation that we’re going to have a lot of over the next decade. But I would say to you, I am perfectly comfortable. That to choose propane today or choose natural gas today, knowing that it was a 25 or 30 year solution. I can really be intellectually honest, it says that fuel can still be cleaner than any other choice of energy I have. Because we’re we’re migrating not only our conventional fuels cleaner, but our renewable blends are carbon zero or less. And so for example, I’m perfectly comfortable talking about carbon zero propane, perfectly comfortable.

Gene Tunny  21:48

Okay, how does it become carbon zero? Tucker, I have to ask you about that. Because when you hear that you think Hang on, how is that? It’s propane. It’s so hydrocarbon how on earth? Can it be zero? Kava? What’s going on there?

Tucker Perkins  22:03

Yeah, I agree. And actually, as a person who I think we’re all better to be naturally sceptical, you know. And so the first time I talked about some modern fuels that had a carbon intensity of minus 273, I’m like, How can that be. But let’s use one example that where we think renewable propane, some sources could have a carbon intensity of minus 300, minus 300. And that would be you know, we’re working on ways to take methane today that escapes into the air. Think about gas drilling, or well drilling, where you just have fairly large amounts of methane that are just skate escaping into the air, because they can’t deal with it any other way, to be able to capture that escaping methane and convert it into a usable product. The scientists have really said consistently, I should give you credit for that, without your innovation, that methane would have escaped in the air. So I’m going to give you credit for now capturing that methane, and doing something with it. And if we can do that something converted into renewable propane efficiently, you know, don’t use a lot of energy, don’t use a lot of land, then the way we would score that today is minus 300. The renewable propane we’re making today, some of the agricultural styles, they they score today is as seven. And I’m, I’m comfortable that by using some renewable power, and by being more efficient in the process, that will end up being carbon zero as well.

Gene Tunny  23:37

Right? So it’s renewable because you’re taking methane that’s otherwise going into the atmosphere. And you’re using renewable energy to extract the propane from that is, is that right? Right.

Tucker Perkins  23:53

So again, I mean, just even go up a level a little broader. We’re taking waste products, and converting them as efficiently as possible. And by the way, all inputs considered, there’s no, you know, there’s no black box where he just stick it over there and say, No, we don’t count once in that black box, everything’s considered. In fact, even as we think about moving these grains from where they are grown and harvested to where we convert them to propane, we have to figure the carbon intensity of that train, then move those grains, but we take waste products, essentially, and effectively convert them to energy, and we calculate all the inputs. And so you know, a good example, we’re growing a product that would be very applicable in Australia camelina plant, we grow it on fallow land, we don’t irrigate it. We don’t put a lot of nitrogen on the soil, and we very efficiently converts to energy. So that’s right now the government here’s corps that has a carbon intensity of six And, and I believe by the time we perfect the process will be zero. That’s that’s how you get to those numbers, rock.

Gene Tunny  25:06

And so where are we with renewable propane? Are we in? Are we still in the r&d or the demonstration or commercialization phase of it.

Tucker Perkins  25:15

So interesting that, you know, we’re making it today in the US we’re making it today we’re selling it today, it is eligible for a lot of the same credits that you get from us from buying renewable diesel or sustainable aviation fuel. And, you know, I’m proud to say I think we’re really, we’ve probably seen the market grow seven fold or eight fold in the last year. And that’s just really all around the activity from making renewable diesel or sustainable aviation fuel. Those other things, I’m talking about agricultural based versions from camelina plan or some other really interesting, a non food cover crops, capturing methane that we’ve talked about early, those are now moving, you know, out of the lab, past the pilot plants and into real production. So if you and I had this conversation a year ago, I would have talked to you about renewable diesel, and sustainable aviation fuel making renewable Propane is a part of that. That’s, that was where the conversation ended. Today, I probably have 13 or 14 other pathways that all have, you know, really strong commercial potential. Yeah. And there are a few really exciting possibilities into the lab that are being heavily funded. So we’re excited about the fact that there’s a lot of waste material. And a lot that easily converts think about agricultural waste, whether it’s animal waste, something, you know, you, you certainly have your share that, you know, in Australia that today has been how we make a lot of renewable natural gas, right, but forest waste, how easily can we convert that, and I’m convinced Gene, that it will be converted to some renewable energy, it won’t all be converted to renewable propane, renewable natural gas, some of it will turn into ethanol and methanol. And I’m a huge advocate of allowing the feedstock that most easily converts into a product. That’s how it should happen. And then we need to find uses. methanol, ethanol, natural gas, propane, renewable diesel sustainable jet. You know, it all has a need in our society.

Gene Tunny  27:31

Yeah, yeah. Gotcha. Can I ask about the renewable dude, so I’m clear, where does the renewable diesel and sustainable aviation fuel come from? How do we make that?

Tucker Perkins  27:41

So today, we make it almost exclusively from used cooking oils, vegetable oils, you know, we could we could make it from a variety of crops, soybean oil, palm oil, something that you know, really is, we don’t we don’t talk about we don’t use it just it’s not really fashionable to talk about palm oil. So today, it’s basically soy beans, and a lot of used cooking oil, that’s really been the primary feedstock for

Gene Tunny  28:12

just on palm oil, you mentioned is not fashionable. Is that because of concerns about the environmental impact? Absolutely. Yes. Gotcha. Yeah. Yeah, it’s a big issue in Indonesia, of

Tucker Perkins  28:24

just, you know, from just from an environmental standpoint, and not really good ability to control the source and to be, it’s to me, it’s a little bit like lithium, right? Or cobalt? Yeah. If we’re really honest, about how we source cobalt today, we have a long ways to go to think about responsibly sourcing these materials. And again, at some point, we’re doing all this to improve the planet to improve our health to improve the quality of life for all in concerned. Right. And I don’t know how you turn your back on, you know, the miners of cobalt in the Congo, right? I mean, we have certainly not improved their lives, in many respects and the things the same probably draws out the palm oil.

Gene Tunny  29:09

Yeah, gotcha. Okay. So, as we wrap up, Tucker, how do you what are your thoughts on how the transition is going? I mean, there’s a lot of talk about the need to get toward Net Zero, obviously, how do you see the energy transformation going in the US? So I’ve covered it in Australia quite a bit on the show. I’m just interested. How do you think it’s going in the states there?

Tucker Perkins  29:33

Well, first off, I compliment you and calling it a transformation and not a transition. Right? You know, that’s a hot button to me, because it’s not a transition transitions are smooth and easy. And you hardly know when you transition. And in the transformation, people fall and stumble and hit their head and some people, you know, thrive and other people lose and that’s exactly what we’re gonna do here. So, I love the fact that you call it a transformation because it is, you know, we’re on the one year anniversary of our inflation Reduction Act, which is really that first massive influx of money in, you know, I said an interview earlier this week, we can see how much money we’ve spent. But it is quite hard to see any benefits we’ve reaped. Now, in fairness, one year is a very short time duration to be measuring results. But I think it’s pretty clear to say that we’re not seeing benefits. And I think that’s one of the areas that we love to talk about, is we’re stepping over easy short term wins to benefit the environment. In this quest for this magical electric grid that could appear, or this magical use of hydrogen, in a new Australia’s light years, I feel like ahead of most in both those areas, frankly. But you know, we’re really a long way from having a hydrogen economy, we’re a long ways from having a true, resilient, affordable electric grid that just produced from solar and wind. And so I’m loving the fact that the focus is coming in on how to how to get to a cleaner climate. And I feel like wherever you go, responsible scientists and engineers are working towards a common goal. I would say in the US, I find often that fossil fuels aren’t equal, right? It’s, it’s quite interesting to me that we talked about coal, oil and wood is dirty. And then we use a lot of coal, oil and wood to generate electricity, which is going to be the next solution. Right? So fossil fuels aren’t equal at all. And I think propane natural gas are two that have a long runway in it just transformation. And, but I love the technology that I’m seeing developed. And I’m loving seeing the market niches that we see propane can play. years ago, we really didn’t talk much about LPG in power generation. And now if I took you around the world, you’d be so shocked how we’re industrially powering facilities in Puerto Rico. We are, we’ve moved so far past residential backup. Now we’re into some prime power applications, residentially and commercially, just today I met with a college that’s going to choose propane for a significant portion of their energy system, because it offers them the best combination of environmental benefits and cost, reliability and resilience. So where we are clearly not even in warm up of you know, where we’re going to be. But I see now engineers, scientist, and really the financing community pulling together to get to a good spot.

Gene Tunny  32:56

Gotcha. Okay. And finally, what about pumped hydro and nuclear? I mean, there I mean, pumped. Hydro is something we’re pursuing here in Australia, nuclear, there’s talk about it, we probably won’t have it. There’s a lot of community resistance to it. But there are some people arguing very strongly for it. Do you have any thoughts on either of those Tucker,

Tucker Perkins  33:16

probably probably have strong thoughts. I don’t really think we ever get to where we want to be with the power grid, until we learn how to make nuclear power, until we learn really how to make it as safely as possible, and how to deal with the waste. But I really think nuclear is going to have to be a part of our solution. Because one, one thing is evident, we’re going to continue to use more and more power, right? Where we’re we want to use our computers, we want to use our data centres. Now. We want to use artificial intelligence. And nobody talks about how that in fact ratchets up our power demand exponentially, right? And yeah, you just don’t really get there without having a significant nuclear base. Now, maybe one day we’ll be talking about fusion. But I’m just not an adult. We don’t have that long to wait. We cannot wait any longer for the silver bullets. We got to take action now. Right. For it’s interesting to me that you’re talking about hydropower, because I want to be such a champion of hydroelectric power. I want to I want to be, but the realist in me knows we’re not going to build any more dams. We’re not going to dam up more rivers just not going to happen. And at least in the US, we haven’t seen even though the pumped power projects we have here are magnificent. I don’t see enough on the drawing board here to create a blip in the supply. And so for us, I find pump storage and pumped power. Something that’s not really even in the conversation right now. I’m glad you all are talking about it. Because as a way to store power and use power when you have a lot of it, and to store it for a time when you need more of it, it makes a lot of sense.

Gene Tunny  35:18

Yeah, we just hope it works out because we’re, we’re betting a lot on it, that we’ll get the pumped hydro to help back up the grid. But one of the projects we’ve got as a snowy 2.0, and it’s just way behind schedule, it’s going to be like five times the original cost. It’s delayed by 10 years. It’s it’s not going well at all.

Tucker Perkins  35:36

You know, we’re seeing that we’re seeing that right now in offshore wind, right. I mean, all the financial models that really were built around offshore wind, those financial models changed significantly, everything became more expensive. And really, right now the projects that are moving forward are the ones that just really felt like they had no choice but to move forward. But those are, again, things change, right? labour costs go up, material costs go up, maybe technology shifts, and gives you every once awhile, a favourable result. But, you know, I think that’s one of the things few people think about in this transformation as well, is just how dynamic everything is right? What’s the cost of power? How long are you willing to contract it? I was thinking today about just mining and thinking about, I just don’t know, Australia is certainly a huge mining centre, it’s a part of your culture, you have a lot of land, that is a part of your culture, no other way to say it, you embrace it to the extent you can, I just don’t think we’re going to embrace it and in the US, right, like you do in Australia. And so I think it has significant impact on our ability to really think about how we’re going to produce lithium, or copper. And so we have to really think about that, I think as a global basis, but we can talk in the US about how we’re going to become independent for lithium or copper. He I don’t believe it for a moment. And it’s not that I don’t want to believe it. But is that I’m well aware of, you know, not that many people want to lithium mine in their backyard, or in their neighbourhood or in their state sometimes.

Gene Tunny  37:20

Yeah, yeah, absolutely. There’s some some big issues there, for sure. Okay, Tucker, any final thoughts before we close?

Tucker Perkins  37:29

No, I mean, I love the opportunity to have this conversation with you. I love the fact that we’re about as far apart geographically as you can be. But we share, we share the exact same desires right to get cut our carbon would be able to live our lifestyle afford, you know, our families a better lifestyle, then, you know, perhaps we had his children. And it is nice to have partners in that in that conversation. Because from this conversation, we’ll get to solutions. We will cut through the politics, we’ll cut through the rhetoric. And I think we’ll get to solutions that were

Gene Tunny  38:05

absolutely, Tucker, I think that’s a great note to end on. I agree with you about the need to be great to cut through the politics on these issues. And yeah, really appreciate all the great conversation and just learning so much about propane, and this renewable propane and how these renewable and sustainable fuels are created and getting your thoughts on their role in this energy transformation. I think I pinched that from you, Tucker, they were in our pre conversation you. You mentioned it is really a transformation rather than a transition. And I’ve chatted with other guests. And their thought too, is that the nature of it is it’s not going to be smooth. It’s it involves lumpy investments, there’s going to be disruptions at times. And yeah, we’re starting to see some of that. So yeah, Tucker, it’s been terrific really value, your perspective on this and your information. So thanks so much.

Tucker Perkins  39:05

I really appreciate you having me. I hope you have a great day.

Gene Tunny  00:06

Welcome to the Economics Explored podcast, a frank and fearless exploration of important economic issues. I’m your host Gene Tunny. I’m a professional economist and former Australian Treasury official. The aim of this show is to help you better understand the big economic issues affecting all our lives. We do this by considering the theory, evidence and by hearing a wide range of views. I’m delighted that you can join me for this episode, please check out the show notes for relevant information. Now on to the show.

Hello, thanks for tuning into the show. In this episode, I catch up with Andrew Murdoch to talk about the transition to net zero greenhouse gas emissions here in Australia. My occasional co-host, Tim Hughes took part in the conversation too. Andrew is the Managing Director of Arche Energy, which describes itself as a clean energy power and infrastructure advisory providing depth of experience to the investment community as it develops and executes clean energy power generation and infrastructure projects. It’s headquarters are in Fortitude Valley, Brisbane, not far from my office. As you’ll hear, Andrew is generally positive about the transition to net zero. And he has that can-do attitude you’d expect from an engineer, but he’s also a realist. He gave us some great insights into the challenges associated with bringing large amounts of renewable energy into the system. And he made strong arguments for remaining open to a range of options such as nuclear power, and for persisting with r&d in carbon capture and storage, a so called clean coal technology. Okay, let’s get into it. I hope you enjoy our conversation with Andrew Murdoch.

Andrew Murdoch from Arche Energy, good to have you back on the programme.


Andrew Murdoch  01:59

Thanks Gene. Good to be here.

Gene Tunny  02:00

Excellent. Tim, thanks for joining us for this conversation, too.


Tim Hughes  02:04

You’re welcome. Good to be here.


Gene Tunny  02:05

Excellent. So Andrew, you got in touch after the conversation that Tim and I had recently with Sir David Hendry. And one of the things we talked with Sir David about was the transition to net zero. And we talked about what was happening in the UK and what he thought about nuclear energy as a possibility for Australia. And we talked about these small modular reactors. So you got in touch with us. And you’ve been on the show before. And you’ve mentioned that you have some thoughts on renewables on how we’re going with the transition to net zero on nuclear energy. So we’re keen to chat with you about that today. If you’re happy to do that.


Andrew Murdoch  02:44

Yeah. Thanks. Thanks, Gene. Yes, happy, happy to do so. Yes, Sir David, raised some interesting points. And so I thought it would be good to expand on some of those a little bit.


Gene Tunny  02:52

Excellent. So to kick off with Andrew, could you tell us how do you think this transition to net zero is going here in Australia? And then we might chat about how it’s going overseas, please.


Andrew Murdoch  03:05

Yeah, look, I think in Australia to date, the transition is going going very well. There’s a lot of excellent projects that are that are happening, we’ve seen a significant increase in the share of renewable energy on the market, and a corresponding reduction in the intensity of greenhouse gases per megawatt hour generated. Each of the states have now got some some ambitious renewable energy targets that they are all working towards. And, you know, we’re starting to see statistics like 25% renewables penetration in states like Queensland and higher in other states as well.

Gene Tunny  03:42

25%? Wow!

Andrew Murdoch  03:45

25% for for financial year 2023, which is, which is fantastic.


Gene Tunny  03:48

So this is the percentage of the electricity generated in the state that is coming from renewable sources, such as solar, and hydro, and it includes the rooftop solar, as well as the big solar farms?


Andrew Murdoch  04:01

Yeah, that’s correct. Yeah. So it’s predominantly solar, wind and rooftop power.


Gene Tunny  04:05

Gotcha. Okay. So we’re at 25% or so here, but we’ve, they’ve got some pretty ambitious targets haven’t they for where they want to get to?


Andrew Murdoch  04:14

Correct yes. So for example, Queensland’s renewable energy target is 50% renewables by 2030. So that’s only another another seven years away. And then 80% renewable by 2035. New South Wales is targeting a 70% reduction in greenhouse emissions by 2035 from 2005 levels. So they are really quite ambitious targets. And as renewable penetration increases, it gets harder and harder to manage, as we have to shift more power from times of high renewable generation such as the middle of the day when all of the solar farms are operating, more periods of high wind, collecting the surplus power storing it and shifting it to times when the wind is not blowing the sun’s not shining is is one of two significant challenges. The other significant challenge we have in terms of significantly increasing renewables penetration is in increasing the transmission infrastructure to be able to collect all of the energy that’s generated in the in the renewable energy zones or areas where the sun is strong and the wind and the wind blows and moving that into the load centres in the cities and industrial areas.


Gene Tunny  05:23

Okay, so what’s the issue at the moment, we don’t have the lines where they need to be.

Andrew Murdoch  05:28

Yeah, so the lines have historically connected the large baseload thermal power stations in places like the Bowen Basin and the Hunter Valley, and connected them to, to the load centres in the big cities and, and industrial areas. So because that’s where the energy is flowing, it’s flowing, it’s flowing from the areas where the coal is to where the where the load is, now it needs to now we need to get the energy from where the wind blows and the sunshine as to where the to where the load is. And that’s a lot more geographically dispersed. And, yes, there has always been transmission lines to a lot of these communities. But those transmission lines have been sized to suit the towns and communities in the area, rather than and of course, that load is much, much smaller than the hundreds and 1000s of megawatts that we want to be transmitting from those areas back into the cities.


Gene Tunny  06:20

Right. So what does that mean? We need bigger, more high capacity lines? I mean, how do we think about that? It’s more expensive then is it? There needs to be upgrades, it needs to be new lines?


Andrew Murdoch  06:30

Correct. Yeah. So so the renewable energy zones are all about connecting the high renewables areas to the load centres? And yes, physically, that means new lines, higher voltages, higher capacity transmission systems into those areas.


Gene Tunny  06:45

Right. And what are these renewable energy zones? Do you know roughly where they are?


Andrew Murdoch  06:50

Yes, so New South Wales has five renewable energy zones. They have the Central West Orana, they have New England, Hunter, Southwest, Queensland released its renewable energy zone roadmap. I won’t try and list all of them. There are quite a few, some of the areas that Queensland are progressing North Queensland, area around Biloela or west to Biloela there where there is already some some pretty good transmission systems, but it’s all about connecting, connecting local farms into the local wind farms and solar farms into the into the existing transmission system, Darling Downs, areas around McArthur wind farm, expanding those expanding those zones as well.


Gene Tunny  07:34

Great, okay. Right. You mentioned that as you get more renewables into the system, you have these issues of like, it’s going to be harder to go to the next stage. I mean, we’re at 25%. So you’re saying that it gets more difficult because then you’ve got more of your power from intermittent sources from the renewables, you don’t have as much from coal or from gas. So is what you’re saying have we got the low hanging fruit already? So the the rest of the fruit, they’re going to be more difficult to pick? Is there any rule as to when you have problems? I mean, we’re at 25% now, I mean, can we can we get up to 50%? Like, what does that entail? Is does that is that when we need the pumped hydro, do we need pumped hydro to get to 50%? How do we think about this?


Andrew Murdoch  08:22

You’re sure, so no, there’s not a there’s not a hard rule, things just get harder and harder. So okay, you know, using the low hanging fruit analogy, you need a bigger and bigger ladder as the as the fruit gets higher and higher. So the driver for pumped hydro or any storage is the volatility in the price. So the difference between the low price and the high price is what provides the economic incentive to put storage in. So the more the more generation that happens at the same time, whether it’s solar in the middle of the day, or wind, when the when the wind is blowing as a ratio against the peak demand. The greater that difference is, the greater the economic incentive is for run for the installation of batteries. From a energy supply perspective, from a security of supply perspective, it becomes a probability game. So you’ve got the probability of the sun shining, and the probability of the wind blowing in various different geographically dispersed regions around around the country on the network. And what’s the probability of any one meteor…, meteorological event impacting the energy supply to the point where we have to start turning power off? The more storage you have on the system? The more dispatchable generation you have whether it’s coal or gas, the lower that probability is the more concentrated your your, your renewable energy resources are meteorologically, if you have all of your solar farms in the one location, for example, and and you get you get rain in that location, well you you’re going to get no generation, whereas if you spread them out all over the country, well, you’ve got a greater chance of there being, of it being sunny in any one spot. And of course, if you spread them out in a line that runs east west, then you’re extending your generation day as well. So…


Gene Tunny  10:09

Yeah, yeah, Tim, do you have any questions for Andrew at this stage?


Tim Hughes  10:12

It is a sort of like more of an overview, sort of like question, I guess, when we look at 80% by 2035. Without obviously having a crystal ball, I mean, it’s there as a target, what are the chances of achieving it? And what does it look like to be able to be 80% reliant on renewable energy with those things that you mentioned that, you know, there are pitfalls with wind with solar, with having hydro, which I understand really acts as like a bit of a battery, so that it can have water pumped to the top during the day while there’s available power and then it can access that power in the evening. With 80%, in your view, is that achievable? Are we on track?


Andrew Murdoch  10:52

Yes. So Grattan did some excellent modelling about a year or so ago. And what they found that was that 90% was a was an achievable target from a market operations perspective. And their modelling was around reliability of supply versus time of day, and they found that 90% renewables penetration that was about the optimum. Now the final 10%, was was made up by gas, when it comes to the probability of being able to achieve it. Yeah, look, with enough pumped hydro, and with enough batteries, yes, you can do it. And certainly with the gas in the system to deal with those periods where the sun doesn’t shine, and the wind doesn’t blow for for weeks on end, well, you can just just run gas for that 10% of the time. And if you’re 90%, carbon free and 10% carbon at gas intensities of roughly half that of coal, you know, that’s a pretty good outcome on average 24/7 basis. So in terms of carbon intensity,


Gene Tunny  11:49

So this is interesting, because, like you mentioned, oh, yeah, say it doesn’t you haven’t got the renewables for for a week or so. Like there could be prolonged periods where you don’t have the renewables or you’ve got very little from renewable. And therefore, if you’re saying, well, the gas is 10%. But then for those periods of time, the gas is going to have to be providing 50, 60 or 70%, isn’t it? So you might need that you need more gas capacity than you would in the current configuration. Is that is that one way of thinking? Is that right?


Andrew Murdoch  12:22

Correct. Yeah, and your gas becomes more of a standby generator. And so in that scenario, where you have very low levels of renewable generation, for a for a long period of time, and all of your batteries are flat, and all the hydro dams are empty, that’s when the gas has to has to kick in. And that raises a whole heap of questions around security of gas supply as well. When you are only providing gas for a short period of time, where do you store it? And yes, pipelines have have linepack capability. But that has to be commercial for the pipeline operator and for the provider of the gas in the first place, as well so…


Gene Tunny  13:04

Yeah, what’s that capability line?


Andrew Murdoch  13:06

Linepack. So linepack is gas that is stored in a gas pipeline, in a transmission pipeline. So we have transmission pipelines that criss cross the country, taking gas from gas fields into the into industrial and city centres, the pipes are typically somewhere between 300 and 600 millimetres in diameter. And they’re pressurised, the more the greater the pressure that that you run the pipelines in the more gas you can store in there. So it kind of acts as a big gas bottle, and a transmission pipeline at the same time. And so but that stored gas is what we call linepack.

Gene Tunny  13:37

Gotcha. Okay. Yeah.


Tim Hughes  13:40

I was gonna ask, actually, because one of the other things with this, with different sources of energy, how does the transition looks so for instance, like just to be able to switch from, from one source to another source to another source to then put gas in or hydro or whatever it’s going to be? Undoubtedly, we’re charting, you know, getting into unchartered waters a little bit, because this is the intention to try and make that work. How big a good problem is that likely to be, that flexibility that will be needed?


Andrew Murdoch  14:08

Well, yes. So this is the beauty of the market. So the market operation is such that the generators will each bid in the different technologies that they have at different price points, depending upon what their bidding strategy is, typically, you’ll bid in such that you you’ll bid in to generate whenever the spot price is greater than your short run marginal cost of operation, your cash costs. So then you’re then generating positive cash flow. The market and the transmission system doesn’t really care where the electrons are coming from, if they see, as soon as there is energy flowing through the system. It just flows through the system and the Australian energy market operator, AMO, they run a dispatch engine, where they collect bids from from all of the generators around the country and every five minutes. It will it will issue dispatch instructions to each of the generators to either output more power or output less power or maintain the same level depending upon what price they’ve bid into the system and, and what level of generation they’re physically able to provide at that point in time.


Gene Tunny  15:14

Okay, so, Andrew, in terms of how we compare with other countries, I remember maybe it was when we were chatting last time, but there are some countries that seem to have high renewable penetration, but it’s, it’s the countries with geothermal. Is that correct?


Andrew Murdoch  15:30

Well, it depends upon what natural resources you happen to have. So if you’re New Zealand, or Iceland, and you happen to have some excellent geothermal resources, and then great tap in tap into the side of the volcano that you happen to have, and grab some of that heat and turn it into power, so yeah, yeah. So that that works very well. If you happen to have a lot of hydro resources, if your a Nordic country for example, or or, again, New Zealand, or Tasmania, then then you know, if you’re blessed with that rainfall and you can harvest it, then, then then you have that option. Mainland Australia is a little bit more difficult. We don’t we don’t have the rainfall to support massive hydro schemes other than Snowy Hydro and Tasmania. So we are limited to solar and wind for the bulk of our, the bulk of our renewable, geothermal is an option, but our geothermal resources are very deep and not not high grade, so quite expensive to get that heat to the surface and turn it into power.


Gene Tunny  16:32

So can I ask you a question about hydro versus pumped hydro? Because you mentioned Norway. So does Norway have a lot of hydro? So is it able to generate a consistent or quite a regular amount of energy, from their hydro resources, they don’t have pumped hydro, they’ve got actual, they’ve got enough rain fall? Or that they’re capturing it? They’ve they’ve set up these hydroelectric dams in a way that it’d be good to have some understanding of that just is there a difference between normal hydro and pumped hydro? How does that work?


Andrew Murdoch  17:02

Yeah, so so the key difference between normal hydro and pumped hydro is for normal hydro, the rain or snow falls onto the top of the hill, or a plateau somewhere, collects somewhere into a reservoir or, or some other collection system up high in the mountains, then you run it through a set of penstocks into a turbine that might be several 100 metres, maybe, maybe further underground. And then it will discharge into the river system, several 100 metres below where it’s collected, as opposed to pumped hydro, where you are taking water from a lower reservoir using cheap power to pump it back up the hill, and then storing it at the top of the hill. And then and then running it back down again, during periods when when prices are higher. Now you can do both in the same scheme. And there there are several examples of of both, so you might collect the your snowmelt or your rain up in the up in the hills, run it through the run it through the turbine once and then go, Well, you know what, I wouldn’t mind doing that the second time, and pump it back up the top of the hill again. And that that is particularly useful for areas where there’s seasonal variations in the amount of water that comes through the system, snow melt, for example. So during the during the autumn, you might, you might pump more water up the top of the hill and use it in pumped hydro mode during the spring, you might just use it as a once through system.


Tim Hughes  18:31

And so that will be something where, for instance, because one of the issues that seems with solar or wind, but particularly with solar here is that we can’t store we can generate more than we can store. Is that right?


Andrew Murdoch  18:44

Yeah. Correct. At present, yes, the generation, the PV generation capacity is significantly higher than our ability to store it.


Tim Hughes  18:52

So the pumped hydro is a good solution to use that excess energy in a way of pumping the water back up. So that effectively having it as an extra battery like that the hydro itself serves as a battery. So you can then use that power in the evening?


Gene Tunny  19:06

Yeah, well, it’s a solution. The question is, is it a good solution relative to other solutions we have for for transitioning to net zero, right? Because it’s there’s a cost to it, isn’t there? I mean, presumably like building these big, these pumped hydro dams. That’s I don’t know how billions of dollars, isn’t it? I mean, it’s huge amount of money that we have to spend and…


Andrew Murdoch  19:28

Correct, correct. Yeah, these are big projects. They’re big civil works projects, billions of dollars, many years. Lots of geothermal risk, lots of opportunity, say lots of geotechnical risk. I beg your pardon. Lots of opportunities for the projects to not go as well as perhaps we first planned


Gene Tunny  19:47

Now geotechnical risk. You mean the risk of earthquakes?


Andrew Murdoch  19:50

No I mean, the risk of rock being harder than you expect it to be.

Gene Tunny  19:54

Ah gotcha.

Andrew Murdoch  19:56

I mean, and I mean the risk of tunnel boring machines getting stuck for months. underground, those kinds of those kinds of exercises. So it really impacts in terms of cost and shedule risk and you know, it’s, it is difficult to, it is difficult to predict what rocks underground will cost to dig. And many a construction company has gone to the wall because of not not understanding geotechnical risk.


Gene Tunny  20:22

Right. Wow. Okay. Yeah, that’s that’s a really good point. Because we’ve got to build two new pumped hydro here in Queensland. And that’s because yeah, we need the storage, because we’re going to be relying a lot on solar and wind, we don’t have geothermal as they do in was it Iceland or somewhere like that?


Andrew Murdoch  20:39

Yeah. Iceland and New Zealand, New Zealand, to a lesser extent PNG.


Gene Tunny  20:44

And geothermal will be good. Because is it 24/7 effectively?


Andrew Murdoch  20:49

Correct. Yeah. So the volcano doesn’t sleep. Right. Yeah. So the hot granite doesn’t sleep so it’s a heat source that is there 24/7? It’s a good baseload reserve so…


Gene Tunny  20:59

Yeah, I guess what we’re interested in is, because there’s an upcoming event at the, It’s at The Tivoli I think isn’t it Tim? I think so, yeah, around the corner from where we are here in in Fortitude Valley or Newstead, and it’s about does Australia need nuclear power? Because we’re discovering that the greater penetration of renewables relying more on renewables, well, we need to upgrade the grid, we need to upgrade transmission lines. And there are all sorts of, you know, huge estimates of what that could cost. I’ve seen a trillion dollars or so, it seems that there’s there’s an argument about all what is really the cheapest cost of electricity once you take into account all the all of these network costs, there was a controversy about the CSIRO levelized cost estimates. Could nuclear be part of the the solution given that there are all of these costs with renewables? And we’re not really sure whether it will, well, I mean, maybe maybe we are sure it will work. This is what I want, I’m interested in your view on to what extent should we be looking at nuclear as a potential backup or a plan B, if this, this current plan doesn’t work out?


Andrew Murdoch  22:09

Yeah, well, we certainly should be considering nuclear as one of the options. The, the engineer in me likes to consider things with a sceptical and enquiring mind. So what are all of the options? What are the ones that will work? What are the ones that won’t work? What will they cost? What are the probability that we will achieve the outcomes that we’re trying to achieve? So in the context of assessing any type of technology, we should be looking at? What is it going to cost? What are the consequences? How does it impact our society? How does it impact our landscape? My personal view is that, that advanced small modular reactors have a role to play, particularly when we’re getting into the very deep baseload. So the power that has to run 24/7 at very high levels of reliability, that’s going to be very difficult and expensive to do with intermittent renewables. And it is possible to do it with intermittent renewables, it’s possible to do it with intermittent renewables and storage and gas topping. But another arrow in the quiver of decarbonisation tools that we could use is small modular reactors.


Gene Tunny  23:21

Okay, we’ll take a short break here for a word from our sponsor.

Gene Tunny  23:55

Now back to the show.


Tim Hughes  24:00

It is a really interesting area, because it’s changing very quickly. I was gonna ask, one of the big costs that gets talked about is the infrastructure. And I know before we started recording it was mentioned about Mount Isa, for instance, and the cost of running the copper string connection, which I’ll ask you to talk about in a sec. But as a general thing, the infrastructure as we currently look at it is extremely expensive. With the technology changing as quickly as it appears to be, is it possible that, obviously decisions have to be made now and action has to be done now, is it possible that some of this very expensive infrastructure may become redundant in the not too distant future with the possibility of, for instance, we haven’t also leading into the conversation about SMRs small modular reactors, which I imagine would require less of this infrastructure, if that was to be the case that they would be rolled out in more locations so we don’t need to move energy over large distances. So I guess the overriding question would be, you know, like with this changing technology, battery storage is obviously a big part of this, where it may not be necessary to put all this expensive infrastructure in place. Now, how does that pan out? Obviously, we have to go with what’s available, with current technology, how do we stop ourselves wasting money on infrastructure that becomes unnecessary, fairly soon?


Andrew Murdoch  25:26

Sure. Good question. I guess you there’s a whole heap of crystal balling that…


Tim Hughes  25:33

There is yeah and I realise it’s an impossible question. And it’s very much a sort of moot point, because this is clearly I mean, it’s all expensive. But there’s a lot of money involved in this. And and it’s, you know, it’s taxpayers money getting invested in these systems. And, of course, it’s contentious. And yet, of course, we have to go with what we know, we can’t put things on to what we think is going to happen. But it appears that is moving in a direction quickly enough that we might be able to, I don’t know, it might be prudent to hold off on some of these bigger things. So sorry. I’ve put about five different questions in there for you Andrew. So the copper string connection if we can go with that. So the current way of moving power over long distances is currently quite expensive yeah?


Andrew Murdoch  26:13

Great. Yeah. So I guess I’ll talk specifically about copper string because it’s an interesting project. And it probably in describing it, it, it probably addresses many of your questions. So firstly, the fundamental reason that you would want to connect Mount Isa to the national electricity markets are currently Mount Isa, Cloncurry and all of the mines that operate off that system operate on an isolated grid. So there’s a small power station Diamantina Power Station that operates in Mount Isa, it burns gas, it’s connected to the Carpenteria gas pipeline, and it provides power to those to the mines in those in that area. The original value proposition and this value proposition still holds true today in connecting Mount Isa to the national electricity market is to reduce the cost of minerals processing in Mount Isa. So if you reduce the cost of power, the bulk of the power consumption in the mount Isa grid is used to make big rocks into small rocks so that copper and other minerals can be can be leached out of it. So if you reduce the cost of power, all of a sudden, you can chase lower and lower grades of ore, your mine lifes get extended, and economic output from the northwest minerals province increases. So that’s the value proposition. If you connect Mount Isa to the national electricity grid, those existing power stations at Mount Isa, they still exist, and they can still generate power. And instead of just selling it to customers on the Mount Isa grid, they can suddenly sell that power to people elsewhere on the grid, they can sell it to you and me here in Brisbane or people in Sydney or anyone else who’s connected to the national electricity market. So it opens up the number of customers to them. You also end up in a situation where you have a high voltage electricity network connection going a long way west into a very high solar flux region. So you can still be making a lot of solar power in Mount Isa at 6pm when the sun’s gone down here in Brisbane, and we can take advantage of some of that geographical diversity in the in the network by building that extension. You’re also crossing over the Great Divide, so going from Townsville to Mount Isa, you’re crossing, you’re going very close to Hughenden. And there’s excellent wind resource. And of course, a lot of really, really sunny paddocks along the road as well. You’re going past Julia Creek and all the vanadium deposits in there. There’s multi pronged economic output that comes out of out of this particular investment.


Gene Tunny  28:43

So vanadium is one of those critical minerals, is it? So this is what you’re suggesting that we it might become economic to, are we mining it already and then we process it there? What would be the advantage of…


Andrew Murdoch  28:56

Yes, so there’s there’s a number of vanadium projects in the Julia Creek area that are going ahead and they they will probably be, those projects will probably proceed with or without copper string. It’s just if they can get lower cost power, then that helps the project. So those projects are going to ship the ore, they’ll either process that on site or ship it to Townsville where it will be, where it’ll be processed, and then either export it as vanadium. They also have some other other products that come with it as well. I think one of them has a an oil shale product as well. So there’s a petroleum product that comes out as well from those projects so…


Gene Tunny  29:33

Okay, good one. Sorry, I interrupted you before was just interested in vanadium.


Andrew Murdoch  29:37

Yeah, and then I guess to come back to the redundancy risk point. So for project like copper string, the redundancy risk is I guess, offset by the fact that minerals production in the Northwest will will continue for some time won’t continue indefinitely. At some point we’ll run out of minerals there to mine, irrespective of that is that the solar farms that are being built out there and the wind farms that have been built out there, once they’re built, they will continue to generate at very low cost forever. Whenever, you know subject to upgrades and stuff like that, you know, you might need to replace your solar panels and upgrade to the next level of technology, etc. But once you’ve, once you’ve developed them, why would you ever turn them off if you’ve got this zero marginal cost power coming onto the system? So I’m not so much worried about redundancy. In the context of putting new technologies such as SMR, or clean coal or any other technology into the grid, well, yeah, okay, they’ve got to stand up on their own two feet, every project has to be economically viable. And again, if I owned a wind farm or a solar farm that lived, lived out on the end of a long along spur or in a renewable energy zone, I wouldn’t be turning it off to make space for a competitor I would just keep keep generating so…


Gene Tunny  30:58

On the clean coal, you mentioned clean coal, that’s not really a thing anymore is it? Because they figured out it was not economic, is that right? The whole carbon capture and storage?


Andrew Murdoch  31:08

Not so much figured out that it was uneconomic, I think we just gave up on it. Which is a shame. If you look to Norway, and the US and Canada, they are continuing with carbon capture and storage. There are some carbon capture and storage projects happening in Australia. Santos are doing a project on the Moonee fields, and of course there’s Chevron during the Gorgon project, and all of the under the safeguard mechanism of any new LNG projects have to be 100% carbon neutral, so that sort of enhances the driver to collect reservoir co2 and reinject it back into into underground aquifers. So so…


Gene Tunny  31:51

That’s just the co2 or the greenhouse gas emissions associated with the actual extraction is it? Because it’s not in terms of not the greenhouse gas emissions associated with the burning in some other countries is it?


Andrew Murdoch  32:03

Correct yes. Yeah. So just the scope 1 emissions so for reservoirs, such as typical Northwest shelf reservoir where there is there is co2 and methane in the reservoir. Yeah, instead of venting the co2 and selling the methane that will now be required to deal with the co2 for all new projects connected to LNG facilities… safeguard mechanism.


Tim Hughes  32:25

So their own process becomes neutral as such.


Andrew Murdoch  32:28

Correct. So back to clean coal. Yeah, my personal view is that in Queensland in particular, we’re doing ourselves a disservice by not pursuing clean coal. Now, that’s not to say that it’s going to be the answer. But again, it could be one of several solutions, or one of several contributors to lower lower carbon power in Australia.


Tim Hughes  32:51

Right, just on that note, so for instance, to get to 80% by 2035. So if clean coal was an achievement that could be done, that would be part of the 80% not part of the 20% remaining.


Andrew Murdoch  33:03

Well, it depends upon how you define renewable. Okay, so yeah, okay, so


Tim Hughes  33:08

So actually, sorry. So that’s the distinction is it’s renewable, not necessarily carbon neutral?


Gene Tunny  33:13

I guess you could say it’s renewable equivalent?


Tim Hughes  33:17

Well, no, it’s a fair point. I mean, like, for instance, I mean, as a consumer, like, you know, I love the direction this, this is going and it’s quick, and it stalled for a long time. It’s not too long ago, Tony Abbott and Joe Hockey, were making it making a joke out of renewable energy. So the acceleration and the take up has been incredibly fast, which is really exciting to see. And so the intention here is really good from the consumers through to the market through to government now, which is great. And of course, like the conversation like this really is like, well, how well can it be done? Is it realistic? And, you know, what are the best choices? Because it’s moving so fast? So clean coal? Yeah, I mean, like anything that gets extracted from the earth is still viable, in my view, if it can be done in a good way for the environment, like, you know, it’s a big conversation, but it’s basically can we do things ethically, sustainably, renewable, etc, that’s, that’s great. But these figures, these, these amounts going towards 80%. And, of course, at some point, 100%. I mean, that would be the ultimate target, I’m sure.


Gene Tunny  34:24

I think that’s, I think, in Australia, that it would be too difficult because of the intermittency and just, you’d need some gas still, don’t you? I mean, no one’s talking about 100% renewable at the moment in Australia, are they?

Tim Hughes  34:34

I can be the first

Gene Tunny  34:36

you can be the first I’m just wondering whether it would even be feasible. I honestly don’t know.


Tim Hughes  34:42

I guess from that all I mean, is like, you know, new technique because of the emphasis and the money and the brains and the work going behind this now, obviously, this technology is moving very quickly. So ultimately, yeah I mean, like we could end up with very clean energy fusion could be at some point in the future. I mean, like, this is decades away. Who knows what may happen? But the direction we’re heading in is a positive one. And yeah, we have to do what we can with what we have currently. Can we go back to the SMRs a little bit because this is something, this is something that was new to me with that conversation we had with Sir David Hendry. Looking into it a little bit like everything else, it’s a little contentious. It does appear to be a cleaner option, certainly than the traditional nuclear reactors. But it’s not without risk, and it’s not without some waste. What are your views on SMRs Andrew?


Andrew Murdoch  35:35

Yes, so I think they’e a good option that we should consider for that very deep baseload generation, that role that is currently provided by coal in mainland Australia. We need to address safety and we need to address waste because they are obviously weaknesses in the SMR option. So I’m going to make some comments. These comments are based on the the GE Hitachi BWRX reactor, which is currently being designed for a project in Canada. So BWR is boiling water reactor. It’s a it’s a reactor that consumes uranium 235, splits those into into through a fusion reaction, the core is surrounded by water, that water boils, the water is then dried and then goes through a steam turbine to generate power.


Gene Tunny  36:23

Sorry, you mean a fission reaction? fission reactor? Yeah, gotcha. I might have misheard


Tim Hughes  36:29

To be fair they’re so close. I had to really work that one out and lock it in. So fusion is the one that’s talked about often is a bit of a an Eldorado of energy production. But we’re not there yet. And it could be some time away. But fission is what we currently have yeah?


Andrew Murdoch  36:44

Yeah fission is what we currently have. Yeah. So yeah, so that’s splitting atoms, fusion is squishing them together. Yeah. The power output is moderated in the in the fission reactors by a boron set of boron carbide plates that move up and down within the uranium to regulate the absorption of neutrons. And that dictates the rate of the nuclear reaction and the generation of heat. So these boron boron carbide plates in a modern reactor is when they’re fully inserted, they will will slow the reaction right down and let it come to an end. So in a modern reactor, they’re held up by a set of electromagnets, should power fail to the reactor, if something happens, then that electromagnet obviously loses power, the boron plates will drop under gravity into the off position, and then the reaction will come come to an end. Older reactors don’t necessarily have that failsafe mechanism, there might have been some mechanical linkage that might have had to push them up rather than rather than let them drop down etc. So, you have this this safety system where if the power goes up, it moves to a safe position. One of the improvements that came out of Fukushima was to introduce reduce the energy density in the reactors so that they could cool naturally using convective currents. So the the the GE material states that the BW RX will cool naturally for up to seven days without any operator intervention without any external power. So when we when we start to look at Chernobyl, and that was an issue with the positioning of the control rods, and Fukushima where the the circulating pumps stopped working. Those two failure modes have been addressed in these new newer reactors. The other comment is that are lower temperature, lower pressure. So the GE Hitachi machine runs at 285 degrees C and around seven and a half mega pascal, which compared to a coal boiler is relatively relatively low temperature and low pressure. So if we were, if I was specking, up a new coal fired power stations today, it would be 600 degrees and 30 MPa, so significantly hotter, significantly higher pressure, so pushing the boundaries of modern material science, whereas the BWRX has a lot more achievable, I guess, more comfortable pressures and temperatures that give you a wider range of materials that you can select from and will last a lot longer with respect to creep life and fatigue.


Gene Tunny  39:20

Right. One of the things I think I remember about these SMRs, I don’t know if we chatted about it last time, or if it was when I was chatting with Ben Scott on on the show, can you just put these where we’ve got existing coal fired power stations, you can replace the the coal fired power? What is it the generator or whatever it is, with the with the actual SMR?


Andrew Murdoch  39:30

Yeah, it looks so in my view, that’s a good location for them because you already have the transmission infrastructure and you already have the water. So an SMR is going to use about the same amount of water as an equivalent coal fired power station, maybe a little bit more because that because those temperatures and pressures are a little bit lower, so the thermal efficiency is not quite as high. So it might use a little bit more water. And there’s no reason why we can’t put some hybrid cooling in there as well to reduce that water consumption. So those issues are all are all solvable.

Gene Tunny  39:42

What’s this hybrid cooling?

Andrew Murdoch  39:45

So the traditional way of cooling steam turbines is using evaporative coolers. So they’re the big hyperbolic cooling towers that one associates with nuclear power stations, actually nothing to do with the nuclear part, it’s everything to do with the steam turbine part. Yeah, so and that basically evaporates water to, to take the heat out of the condenser. A dry cooling tower is more like a radiator in your car, where you’re just using the air circulating through the radiator to cool it, a wet cooling tower will an evaporative cooling tower will will be more efficient, because it drops the temperature to the dew point temperature rather than the dry bulb temperature, which gives gives you a couple of percent of efficiency in your steam turbine, which is very valuable. And then if you do a hybrid you the reason you would do a hybrid is essentially to save a bit of water, drop the high temperature heat out using the radiator and then still achieve those lower temperatures by by taking maybe the last 10, 20% of heat out using evaporative cooling.

Gene Tunny  41:12

Right. Okay, gotcha.


Tim Hughes  41:15

So there’s still some radioactive waste from SMRs. Is that right? So it’s reduced. So compared to the energy it can generate, it’s less than a large nuclear station, nuclear power station, but there is still some waste percentagewise, I guess, compared to the power generated,…


Andrew Murdoch  41:35

Correct Yes. Yeah.

Tim Hughes  41:37

Radioactive waste. I mean,

Andrew Murdoch  41:35

Correct Yes. So yes, it does generate high level radioactive waste. And the most significant part of that is the spent fuel rods. Now the spent fuel rods can be reprocessed. It’s I can’t remember the ratio. Now it’s something in the order around 95% of the energy remains in, in the uranium fuel rods after they’re removed from the reactor so that reprocessing which is essentially is, is refining the amount U235 and removing some of the U238. And once it’s reprocessed, it can go straight back in the reactor and run for another…


Tim Hughes  42:08

So is this transuranic waste? Is that right? Because this is David Henry mentioned about he referred to transuranic waste, which can then be reused by the SMR. I’m just repeating this is. I mean, this is we went over this briefly with Sir David. So it would be something we could put to him directly. But that was my understanding that there was a certain amount of the waste that can then be used as fuel by the SMR.


Andrew Murdoch  42:37

Yeah, correct. Correct. Yeah, the bulk, the bulk of it can be reprocessed, and reused. Now, that said, even if you don’t, and a lot of countries don’t reprocess their waste, because it’s quite expensive compared to to producing new fuel rods from raw uranium, even if you don’t you’re just still only generating a very small amount of waste.


Tim Hughes  42:57

Radioactive waste is pretty serious stuff for a long period of time. So the disposal of that, I guess, must be quite expensive, let alone the dangers of handling and processing that


Gene Tunny  43:08

We’ve got a lot of places you could bury it in, in Australia, Outback Queensland, Australia, you know, plenty of place.


Tim Hughes  43:17

So, um, but the thing is, obviously, with the aim for clean energy, it’s an uncomfortable addition to the suite of energy provision sources that we may be looking at. However, I mean, it was interesting, because I didn’t know of it until just recently with the interview with Sir David Hendry. He’s a climate econometrician so very keen on having, you know, a clean, ethical source. And he was a supporter of this. So it’s certainly interesting. And, you know, it certainly is something that needs to be considered because obviously, the alternatives, everything’s got to pay off at some point.


Andrew Murdoch  43:55

Yeah. And that we shouldn’t we shouldn’t be too glib about the waste issue. It is a serious, it’s a serious issue. And, you know, one of the one of the cons on the pro con balance of of any technology, my personal view is that if we do go down an SMR path that we should also be committed to reprocessing. Yeah. So look, I think the this conversation sort of highlights how complex energy is and that in any technology choice we make there, there are trade offs that we have to make. If we look at things like land impacts, okay, well, in nuclear, yes, you’ve got to, you have to store the waste somewhere. So that’s going to have an impact on land. And yes, we’ve got some good geological characteristics about Australia and lots of space. If I look at Coal, for example, well, you’ve got to dig holes in the ground and that has an impact on the land if you want to burn gas you’ve got to go and you’ve got to go and sink gas wells and that has an impact on the land if you want wind then you’re going to have to go and go and find some windy hills that are probably covered in some nice gum trees and and put up some wind turbines. If you want to put up solar farms, you’re going to have to go clear some bush or take some agricultural land or grazing land and turn that into solar cells. So there are no free lunches.


Tim Hughes  45:05

And if you want to store the energy, you’ve got to build the batteries.


Andrew Murdoch  45:09

Build the batteries or dam, the dam, the valleys or whatnot, all of these things, there’s a bill to be paid one way or the other. So the best we can do as, as a community is to is to assess all options. On a level playing field basis with a with a sceptical and enquiring eye. What is the best engineering? What’s the best economics? What’s the best ecological science? Can we afford it? will it produce the ecological social power reliability needs that we want? Or is it the best compromise of all of those?


Gene Tunny  45:42

Yeah, yeah, absolutely. Based on this conversation sounds like we should be considering some more options. Maybe we’ve tied our hands. Because we’re not talking about potential role of nuclear, we’re not talking about potential role of clean coal, or there’s less focus on that, then there once was. This has been amazing again, really good. Good for us, because this is such a complex area. And I mean, I’ve got my own thoughts, but I don’t know enough about the engineering to be able to speak authoritatively on it.


Andrew Murdoch  46:15

Now. Look, it’s been a good discussion. Yes. Thank you. Thank you for the opportunity.


Gene Tunny  46:19

Oh, it’s a pleasure, Andrew, we’re always, always happy to chat. And yeah, it’s good to get your insights on the transition to net zero. So Thanks, Andrew. Thanks, Tim.

Coming up on Economics Explored.

Josh Stabler  00:03

So we have a known urgency that we need to get rid of carbon out of the atmosphere because it is causing issues with regards to climate change, our ability to shift that rapidly, may be outside of our economic grasp. That’s the danger.

Gene Tunny  00:19

Welcome to the Economics Explored podcast, a frank and fearless exploration of important economic issues. I’m your host Gene Tunny broadcasting from Brisbane Australia. This is episode 170 on the Aussie energy crisis and the transition to net-zero, not just in Australia but around the world. I’m joined by Josh Stabler Managing Director of Energy edge. Energy Edge is a Brisbane based advisory firm specialising in energy markets. Also joining the conversation is Tim Hughes, who helps me out of my business adapt economics from time to time. It’s great to have Josh on the show because energy has been very topical lately. High coal and gas prices, largely as a result of the war in Ukraine that pushed up the costs of power generation worldwide. Also, a cutback in maintenance during the pandemic has compromised generation capacity. Also increasing prices as Josh explains in this episode, just how bad are things energy markets, Josh helps us understand what’s been happening and what’s to come. Please check out the shownotes relevant links and information and for details where you can get in touch with any questions or comments. Let me know what you think about this episode. I’d love to hear from you. In the show notes, you’ll also find a list of abbreviations. There’s a lot of them when it comes to Australia’s energy sector, including any M for national electricity market and our Zed for renewable energy zone. Righto. Now for our conversation with Josh Stabler on energy markets. Stick around for the end of the conversation for what I think are the big takeaways. Thanks to my audio engineer Josh Crotts is the assistance in producing this episode. I hope you enjoy it. Josh Stabler Managing Director of Energy Edge welcome to the programme. Thank you for having me. Oh, it’s great. Josh. Tim, who’s joining me as well. Tim, my occasional co host, recommended you as an expert on the gas market and energy in general. So I thought it’d be good to have you on the show. So Tim, thanks for that. And good to have you on the programme again.

Tim Hughes  02:18

You’re welcome, Gene. Good to be here. Hi, Josh.

Gene Tunny  02:20

Excellent. Okay, Josh would be keen to know about your role at Energy Edge. What is Energy Edge? What, what do you do at Energy Edge, please?

Josh Stabler  02:30

Sure, so we’re a small boutique advisory firm in the energy market, we have sort of two different arms of our business, one sides, our advisory sites. So that’s helping businesses in the wholesale energy market, understand their exposures, that’s with both traditional assets and renewable assets. And on the second side, we have our software arm of our business. So we have our own deal capture system, we have our own risk and analytical system. We have a gas market analysis tool, and we have our own edge report, which we talk about things that are going on in the industry.

Gene Tunny  03:02

What do you mean by exposures? What are they exposures toward?

Josh Stabler  03:05

Oh, yes, so the commodity exposure. So we we we delve deeply into understanding what the business are, how it makes money, how it pays for its energy, and then using that commodity exposure, where then we’ll say simulate out the exposures that they have on making a sort of at risk assessments of the money that they could make. And then from that you can go into deep sort of risk metrics. So you can work out a business’s probability of exceeding certain levels, and that’s known as at risk modelling.

Gene Tunny  03:39

This is Monte Carlo, Monte Carlo simulation modelling. Yeah, good one, using At risk. That’s one of the tools you can use. Right. And what sort of clients

Josh Stabler  03:50

Ahh yes, we’ve we’ve actually supported about 80 to 100 energy businesses on the East Coast, which surprised me sometimes I never wouldn’t think there’d be that many. But, you know, we help all sorts we help, you know, most of the Queensland Gox, we’ve really supported. So we’re actually heavily involved with the setup of Cliniko, which is the latest Queensland Government generator that took over all the renewable projects in 2019. So we came in, help them set up their risk systems and help them get started ready for day one, and then they flip went on and did their own things themselves.

Gene Tunny  04:25

Right. So this is one of the Gox the government owned corporations here in Queensland, that’s looking at renewable energy options for the Queensland Government. Okay. Right. That’s great. Sounds like quite a nice portfolio of clients. And that’s great. Yeah. Okay. Yeah. Tim, did you want to kick off with the first policy or economics question?

Tim Hughes  04:54

Yeah, absolutely. So it’s funny we’ve we’ve all talked about this at different times. So cobbling it together. We’re gonna start with Josh, a summary of how we got here, because I know you’ve talked about this before. And I think getting an understanding of this then helps with the conversation we will have about where we go from here.

Josh Stabler  05:14

Yeah, definitely. So how do we get here is such a, you know, an open-ended question, but in terms of, what are we looking at there. So during winter 2022, in Australia, we saw unprecedented levels of pricing. So the electricity prices settled at $300 a megawatt hour for the quarter, the highest ever previously was about 170. And this was across all the regions. So Queensland, New South Wales, South Australia, and Victoria, were all at record high levels. And this was an accumulation of so many different things that have happened over the last few years. And if we go back two years ago, we have to go through the traumatic experience, again, with going through COVID was that during COVID, we had travel restrictions and congregation restrictions, which means that you couldn’t bring expertise from international space, and put them together to do preventative maintenance. And because we didn’t do the preventative maintenance on coal generators on gas generators that lowered their reliability of those assets. Now, the exact causality of each of those is not perfectly known. But what we started seeing was a rising of unavailability of the coal generators. Now, as we move forward through time, we started seeing other international things starting to change. The, the war of Russia and Ukraine was in March this year, but they actually started reducing their supplies into Europe at the end of 2020. So by the time that they’d reached the point of the Nord Stream failure in July this year, they had actually stopped delivering mushroom to Northern Europe, had lowered their deliveries from 17 petajoules, a day to 1.6. Now, that’s 16 petajoules less now that seems like a big number. And it is a big number, it’s actually the equivalent of 95 million tonnes of LNG, which is 25% of the world’s LNG cargoes. So the extraction of one country’s deliveries to Europe was the equivalent of 25% of the world’s LNG. So it’s a it’s a big, big variation in terms of this is probably the largest shock in terms of supply shock, ever, like I know what the equivalent would probably be the 70s sort of oil shock conditions. So it’s an amazing sort of outcome. But it started happening well, before we actually got to the point of war, which meant that we actually started seeing gas prices in the international space rising from September 2021, six months before we actually had the the actual war. And that led to a scarcity of that of energy starting to appear across the planet. And by the time we got to April, in Australia, we’d actually been buffeted away from this, we weren’t seeing any of the higher prices until we started in April. And that’s when it’s first started seeing a rising of the of the energy prices. This is on two fronts, one was on the coal international coal prices which reached $450 a tonne, which is the equivalent of around about $25 a giga Joule in the in the coal pricing. So that means that coal was not cheap. Coal was very expensive.

Tim Hughes  08:24

What was the regular price?

Josh Stabler  08:27

 Yes, for the first decade of the market, it was $1 a giga Joule for coal and $3 or Giga Joule for gas. So that’s in the early 2000s. And progressively gas prices have risen and fallen. But the coal prices have stayed in that sort of $1 to $3 range. So to see it go 10 times the level is really just driving up an underlying input cost. And then by the time we got to May, we had our first event, the event of the roundabout, the 28th of April through to the sixth of May, was when we first saw a sharp increase in the electricity prices. And that was primarily driven by a large reduction in availability of coal generators. And so we saw a spiking of sort of 30% of the fleet was completely offline during May. In New South Wales, we’re talking 40-45% of the fleet was offline. So this is an unprecedented level, like a AMO forecast 12%. So we are three, four times the height in terms of unavailability of the coal generators during that period that caused electricity prices to spike. Two days later, gas prices spiked. So it wasn’t a gas rose and caused electricity to price up. Its electricity went higher and that caused the input costs to follow it up. So we had and once that once the dam had broken once we had the gas prices jumped up to around about $30-40 it connected to the international price which coincidentally was around about $40 a giga Joule, but just pure coincidence. And when once it reached that point, we started having the prices remain in that area. Now, the coincidence wasn’t that the price joined up the coincidence is that in the late 90s, we decided that the market should have a cap, the market cap should be $40. Nobody thought about that $40 cap when thinking about the Ukraine war in 2022, she just happened to be in a note number that worked out very nicely. And once it came that $40, we’ve just had it stay that level. And we’ve had the market go into a price administered state. And then during that, that level, there we had very high electricity prices. But we didn’t have shortfalls, they weren’t customers that were losing the ability to consume. They were just paying a lot in the spot market for those for that generation, that consumption.

Gene Tunny  10:52

Right. So look, there are a couple of things I’d like to follow up on there. Josh, you mentioned that COVID meant that we couldn’t get people over to do maintenance on coal-fired power stations and gas-fired power stations too. Yeah, right.

Josh Stabler  11:10

An outage is literally bringing expertise and putting them really close to each other in a kind of confined space. So we couldn’t get them in because they couldn’t fly from overseas. And when they were here, they also couldn’t do the work. So what we did was a lot of the generators moved their outages just to the next slot. And the slots are normally the April, May or March, April, May. So the shoulder seasons in terms of weather. And the second slot is in the September, October, November period, where you also have a lowering of demand. So you’d normally fit the outages in there, and they didn’t. So they moved them into the next area. And eventually we just squeezed them all together, and then assets just started to fail.

Gene Tunny  11:50

Yeah, that’s interesting. Something that Tim and I are interested in for in terms of, it’s another one of these potential world costs of lockdown or costs of COVID policies that are on the year, the negative side of, of COVID, or the cost side in a cost benefit analysis. So I have to check with Judy Foster’s included this in, in her analysis because we went to an event a couple of weeks ago in Brisbane here on pandemic and managing the pandemic. And there’s a lot of discussion about the costs and benefits of lockdowns. I mean, that’s, that’s not for this conversation. But I just thought that’s interesting as another cost of those policies during COVID.

Josh Stabler  12:42

And it’s not just Australia, the French nuclear facilities are all having an unheard of levels of maintenance right now. Because again, they also had to delay their work. So there was just that there was just a period of and so that that created some of the false security because in 2020, nobody had outages. So everybody had extra supply to the market, which caused prices to fall. So it wasn’t just that we had a lot lower demand, we had a slightly lower demand because of COVID. But we had an incredibly high level of availability of assets. Because no one did any work. No one was doing any work. But the repercussions of that are that there’s an increased unreliability, but be they’ve got it then do that work. You can’t avoid it. There are statutory obligations, you have to actually do it within a certain time period. Otherwise, you’re breaking the law.

Gene Tunny  13:32

Josh, can I ask you what’s the connection between the domestic price paid for gas in Australia and the international price they’re linked?

Josh Stabler  13:41

They are at time. So we’ve we had a very, very strong relationship during 2019, 2020 and early parts of 2021. And then in mid 2021, electric the gas prices domestically jumped up very rapidly, primarily due to domestic issues, domestic supply concerns, and then the gas prices internationally started to rise and they rose steadily from 10-15, 20-25, 30, $40 a Giga Joule, but the Australian Government gas market after about October or September 2001, all the way through to April was only about $10 a giga joule. So we had this rising International and a very low flatlined was still higher than historical numbers, but it was very low in relative terms. And the relativity really matters for a lot of businesses. If you are a fertiliser business and you sell fertiliser, you are a price taker, you take what the international price of fertilisers are worth, and that is priced on international price of gas. So if you have a relatively low price that absolutely high, you are still in a strong position. Whereas if you are a domestic customer who sells domestically then the absolute price is a problem for you because you’re passing that on to a domestic an audience who have to take the higher price. And that will directly increase their, their outcomes, because there they are a price setter themselves. So that, that differential there matters, especially over the medium term in terms of what that does for certain businesses. Now, once we got to make we, that’s when it joined up, and we had lots of periods where the domestic and international were about the same. There are periods where it looks like the domestic is cheaper than the is more expensive than the international but the international price was jumping $10 a giga Joule, every couple of days. So the volatility was more to do with the when you sample the data more than it was to do with the market price it was moving between 40 and $60, depending on the international experience at the time. You know, when Russia first did that change in their availability, the market moved to $20 in a day. So it gets a bit hard when you’re trying to say, well, what is the exact outcome, in general for the year substantially cheaper than almost any other country other than, say, the US and Canada, Australia in terms of gas pricing. Because most other countries are highly linked, you have a Japanese Korea market, okay, yeah. And you have the TTF, which is the Dutch price for gas, both of those have been elevated in the 60s $70 for Giga Joule equivalents for the entire year. And Australia had 40 for about two to three months, and has had 15-10, 15 for the rest of the period. And long term contracts have been in and around about $12.38, I think was the number that the ACCC reported on so substantially below where the international prices are. Now there are some people who have offered very high prices. But that doesn’t mean that anybody traded there. It’s like going and saying, I asked a hotel. Well, I thought price for a night was and I asked a guy on the street, if I could buy his house, they came in at different prices. You’ve got somebody who doesn’t have any guests available to sell, and you ask them to sell you gas, and they’re going to obviously offer a very high price.

Gene Tunny  17:03

Okay, so I just want to make sure I understand what’s going on. So is it the case that the gas suppliers or the big gas companies, they’re they’re entering into these longer term contracts with their customers, and they’re doing that at a rate that’s much lower than the spot price, because they know that will that spot price is just temporary. That’s what’s going on.

Josh Stabler  17:27

And it’s just for short periods of time that those prices are at that very high levels. So you’re not seeing that pass through that long term contracts unnecessarily getting done at $4. There are, if you go to businesses that do not have any gas, yeah, it’s already in you ask them to give you a price, it’s going to be high. But that, but that post, that business doesn’t end up doing the deal. And that’s what we’re seeing. And when you look at the ACCC report they’ve got the price range was between 10 and 60. But the price ended up being 12. So it’s yes, there are some numbers that look, and they are frightening if you are a customer, looking at the deal like that, and trying to make it work. But most of the ones that were especially the ones that made the media were related to the accident of western energy, which went broke in late May. And the basically, businesses were then going out to so that that retailer had to give their contracts back to the retailers last resort. And that didn’t that those prices were back at the tariff rate. And they were very, very high. So there was some bad media around that. But in general, most customers who have gone to long term, producers have had prices in the order of 10 to $14 a giga Joule right, not on a weighted level. Is it anywhere in the 30s or 40s?

Gene Tunny  18:54

Okay, we’ll take a short break here for a word from our sponsor.

Gene Tunny  19:29

Now back to the show. I’ve got some more questions. But Tim, I should ask if you’ve got any questions for josh.

Tim Hughes  19:36

I know between the three of us we could talk for days. For us and for everyone else who might be listening, we should not. However, so if you did have any more questions with that Gene, what I was going to come to and we might want to move on to this after if you have any questions to finish, but basically, because we’re in this fascinating point in our history of our time with emerging energy markets to clean and green options that are coming, the opportunity or the challenge to get to net-zero. So that’s what I’d like to put forward for the next part of it. So if you’ve got anything to add from what we will do that first.

Gene Tunny  20:18

I might just ask you about the risk of what happened earlier this year, happening again, it sounded like that there were some specific circumstances the fact that there wasn’t this maintenance going on, in their catching up with maintenance, does that mean, we won’t see another repeat of what happened earlier this year?

Josh Stabler  20:42

Okay, so, I guess, there’s two parts to that we have the problems that we know that are deterministically at fault. Yeah, which is that we know that there is some coal supplies that are low, some of the local mines at say Mt piper, in near Newcastle, have reaching end of life, and they will need to get coal from train links. And the train links have a limitation in terms of the delivery. So we know there are some facilities that will be energy limited by the fact that their suppliers are constrained. That’s the deterministic issue. On the probabilistic issue, we had outage rates of three times what we anticipated during May and June periods. That of those were random events. So they weren’t failure, reliability failure, they are a probabilistic event, they there is a chance that those numbers could come back, there’s chance those those things, as we are getting closer and closer to the end of life are these assets that are less likely to spend the money to go and fix the power station to be ready. Because they don’t, they won’t recover the profitability. And that’s that there is so if you’re only going to survive five years, and you want to spend $100 million, you need to make an extra $20 million out of that asset every year in order for that to even makes sense. And if your input costs are high, then you won’t go and do that. So that’s why we’re seeing a whole lot of power stations, even in a very high price environment. But it’s also a high cost environment, are worried about what that means for them as they get closer to their end of life. And that leads us to that, I guess, if we can carry on to the next question is what happens in terms of as we get closer to transition. And the complication of transition is that it is by default, disorderly.

Tim Hughes  22:38

So this is transition to new energy sources.

Josh Stabler  22:40

As you transition anything from any old, anything old into anything new, you are going to hit this issue in regard to how you get somebody to give up their space for the next person. Now, if a power station has no goal, no plan for profitability over the next three years, then you would be better off to turn off rather than lose money three years in a row. So that means that you’ve got this, you don’t get an overlap in a transition. Normally, you get old assets who are there will want to exit because they see no path to profitability. But we don’t have a solution yet, because that hasn’t come on yet. So we have a renewable wave and a battery wave, and we have a decline of the coal. And if you don’t act to try and keep them so that they overlap, then there will just be a gap. And if you have a gap, then you’ve got an issue because then the power stations as they become less reliable, will fail. And in fact, when they fail, they will withdraw their capacity from the market, which will cause prices to rise. Making them the reason why the prices are high is because of their failure caused the event. So you actually have to that, and that leads you to part of the policy plan, which is how do you keep something online that doesn’t make money. And that’s where you had starting to talk about capacity markets or anything else to try and social licence. This is why a most said that you’ve got to give three now three and a half years notice before you can exit is because you need to tell them in advance that you’re going to leave. Now the obvious response was origins, which was if I had to tell you three and a half years, I’m just gonna tell you three and a half years and I’m just gonna make a different decision at a later date if I need to. If I get close, and I want to keep it online, well, you didn’t tell me I have to shut and three and a half years. I can just keep it on for another two years with a year’s notice. And I’ll just keep it going. But if I’m forced to make a notice then I’m gonna give it early. And then I’ll update it if I need to.

Gene Tunny  24:48

Yeah, good point. Good point. So amo was the Australian energy market operator. And yeah, it’s interesting. This I mean, I’m, as an economist, I’m rather laissez-faire. I’d prefer to just to rely on market hours, the market as much as possible. But yeah, with energy, you’ve got to take into account the fact that you need to keep the power on you need reliability. So we need, we can’t just rely entirely on the market. And that’s why we’ve got this Australian energy market operator that’s overseeing things and trying to get the right policy setting. So we do have, we don’t end up with unreliable power. And we don’t have to have blackouts in that horror show scenario.

Tim Hughes  25:32

I see. Am I right in? I think it might have been one of your podcasts Josh, or something I read recently, and it was a rant. There, there is gas that is used as a backup currently, for that kind of situation where it is expensive, but it kicks in and that can sort of cover any shortfall. Is that right?

Josh Stabler  25:52

Yeah. And it’s, it’s important to like, when sometimes when you think about what is the what is the idea, you can think globally, you’re like, Okay, well, nuclear is going to work for the world in terms of meaning things because of the problems that some countries have. But Australia has the situation we have, we have a lot of sun, we have a lot of wind, we have a LNG export capability that is delivering gas offshore, all the time. So if we get ourselves into a situation where we are short of wind and short of, of sun, we actually have this enormous amount of gas being delivered, that can be interrupted for a short period of time to deliver that energy back into the grid. And the amount that has been delivered is the equivalent of the entire electricity market. So the four petajoules, that goes off is approximately 100% of the net. So if you actually brought it all down, you could power the whole network if you had enough power stations. But what it does is it provides resilience. Now, not every country has an LNG export option. And it’s not saying that we need to use the gas all the time. In fact, we only want to use it when it’s required, because it’ll probably cost us more to interrupt them. So if we had a commercial arrangement where we could say, give me your gas when we need it, and we’ll pay you some money for it, well, then we almost never have a reliability issue. So long as we can get that gas where it needs to go.

Tim Hughes  27:21

I mean, that would obviously cause some problems with markets. So you’ve got to keep a consistent supply to the current customers overseas, etc. So that might be in a sort of like a short emergency sort of situation.

Josh Stabler  27:33

Yeah, a percent of theirs is a huge amount of gas for the domestic market. So a percent of a day is still 40. It’s like 150 megawatts, 24 hours a day. So it’s 1000 megawatts for six hours, it’s a huge amount of gas that can be moved through into power stations to meet the short term problem.

Tim Hughes  27:55

So with the broader view of where are we going, you know, what’s, what are the options open to us? What are the opportunities for Queensland and Australia in particular, but there was clearly a lot of choices about, you know, renewable energy is obviously growing very quickly. It appears to be green and clean, which I know is a little bit of a side conversation as well. You know, everything has some impact of some sort. But that’s the direction we’re heading. Net-zero is the term that we are all familiar with, that covers it all as in like, whatever we’re going to be doing, it’s not going to be harming the planet. That’s pretty much what the goal is. And so we’re in this transitional period that we’re entering now. So from gas and coal in towards these different areas, and like you say, gas may form a part of the contingency or the emergency supply. So we’ve got renewables, we’ve got wind, we’ve got solar, waves, hydro, all these different things, in your opinion, and your experience. What are your views on these new available sources of energy?

Josh Stabler  29:04

So if we separate it into two parts, one is can we get the electricity grid towards a greener environment? Yeah, we have moved a lot further than most people think. So when we signed the Paris accord in April 2016, so six years ago, six and a half years ago, we had an a carbon emissions for the electricity grid of 171 million tonnes per annum, 171. And this year to a couple of days ago, we were just below 120 million tonnes. So we have reduced our carbon emissions and our electricity grid by 40%. In six years.

Gene Tunny  29:41

Are we talking about Australia or Queensland? Australia?

Josh Stabler  29:45

Australia wide and so in the last couple of days, this is the gold period of the year is the golden period for renewables. It has great sun, no much demand, fair bit of wind. We are sitting in Most days at about 65% renewables during the day, and about 25 to 30% renewables every night.

Tim Hughes  30:06

So that 40%, so 40% reduction in six years. Yep. And that’s purely attributable to these renewable energy sources.

Josh Stabler  30:16

Yeah, it’s basically a one for one reduction increase in renewables, one for one reduction in brown coal fired power stations. So that was it, certainly for the first like four years, and then it’s progressively eaten out some of the black coal, that appears to be really first it’s very, very fast, quite a lot. We’re moving 10 million tonnes per annum reduction. That’s on the electricity side. And we are now we’ve now you know, we’ve got days when we’re more than 50% reduction in terms of our carbon emissions, which is, which is great. That’s really, really wonderful. The problem is, is that it’s not the only thing that our requirements our Paris Accord is not electricity market requirements, it is an economy wide, starts getting a little bit confusing, which is that you cannot use renewable solar panels to meet our agricultural emissions requirements or our industrial requirements. But there are still good news stories in it. As we bring in electric vehicles, we move away from inefficient oil to efficient electricity. And as our carbon emission of our electricity grid becomes cleaner and cleaner, it has a multiplicative effect. Now, five years ago, because the ratios change every year, five years ago, the ratio was 36% was our electricity, and 18% was out was transportation. Now, this is where I’ll jump into some of the numbers for this so EVs, we have 15 million cars on the road. Each EV is at two kilowatt hours, if you had them as a Tesla mum, Tesla Model three, just as far as an example, which makes it 1200 gigawatt hours worth of storage, which is about the equivalent of 250 Wivenhoe, and why Wivenhoe is able to support about 1000 megawatts worth of renewables.

Gene Tunny  32:03

So that’s if everyone in Australia had an EV. If we replaced all the cars, on the road with EVs, we would have how many Wivenhoe dams?

Josh Stabler  32:12

250 Wivenhoe’s in storages which can do 1000 megawatts, which makes it 250,000 megawatts worth of hydro of renewables, which is more than we use switches will far more than we use. So we actually only need about 15% of the equivalent of cars moving down in order for us to have a situation where we have enough storage from cars. But cars don’t plug into the grid every night, we need to have them absorb them the right time, there’s a whole lot of, you know, complications that come around that plan. But it’s just a point of what is an opportunity available to us, we have so much storage there that would need to be replaced. Because at the moment, we have all these cars with their engines, and all they do is drive people. Whereas if we had them being engines that were able to be electricity driven as well, they would have a they would have a role in this market. Now, that is a wonderful vision for 2040. Okay, but as a idea of the same problem they have with any bridge, if you start a bridge at one side and start on this side, you’ve got to make sure they meet in the middle, you can’t just have a dream of where you want to be in 2040 and go off and just hope it’s gonna work out. You have to aim the bridges at each other. And that’s where it gets complicated, is how do you transition across. And right now our danger, is it we’ve seen what happens when things don’t go right, and it’s unpalatable. It is politically unpalatable. Electricity is not run by the governments anymore. But it’s politically considered to be run by the governments. So having it move fast is something that people can not accept, that it’s not politically acceptable. So therefore, if you have these another event like this, then people will start giving up on wanting to transition because I think that that is the reason why it’s happening now. Is that the reason? Well, there’s it’s far too it’s not you can’t point to one thing and say there’s definitely been fault on multiple sides of the fence here because renewables have made coal, not make money which has made them unreliable and made them unreliable before they have to exit and renewables are not ready to take over the role yet because they haven’t got the cost structures in order to do it. So we’ve we’ve got one abdicating the role and the other one, a child who can’t take over it.

Tim Hughes  34:34

So what’s your feeling on that? Josh? Like? Because I mean, is it just the transition is happening too fast? Or is it? Are there other things that we need to consider?

Josh Stabler  34:42

We’ve we’ve, we have a known urgency. So we have a known urgency that we need to get rid of carbon out of the atmosphere because it is causing. It is causing issues in regard to climate change, our ability to shift that rapidly, may be outside of our Economic grasp. That’s the danger.

Gene Tunny  35:02

Okay, that’s a good point. I think I know what you mean. But what do you mean by economic grasp?

Josh Stabler  35:08

Exactly. So it’s the cost of solar falls 36% for the doubling of capacity. So if you wait until you’ve doubled the amount of capacity in the world, you get at 36%, cheaper, wait for your next installation. So that part of the deflationary learning curve that we have, right, so you are highly motivated not to invest now, right and wait for it to be cheaper, and then be beat everybody on the lower cost structure. All other things being equal, not all other things are equal, because initially, you have high income for being in a scarce market. So the initial investments of PV got paid 42 cents a kilowatt. And there was a really good incentive for those first people to invest in solar while it was expensive. Yeah, but eventually, you’ve got to compete in is this worthwhile in the long term. And that same applies to batteries, batteries are falling very rapidly. And if you invest, now, your income stream is high, but your costs are high. And eventually, if you don’t get the right deal in place now, then eventually, someone’s going to come along and eat your lunch. And that gets harder, because you’ve and that’s what does that lead to? It leads to, if you accelerate the process, it will cost money. Is that an unpalatable level of money? I don’t, I haven’t clearly worked out, it’s got better, if we had accelerated faster, five years ago, we would be a very expensive system. But we are accelerating now and batteries are coming on. And they are likely to have a heavy impact because we are having a under normal circumstances a very negative during the day price and a high evening peak, which gives a very large arbitrage, temporal arbitrage, buy low sell high. And therefore people are incentivized to put in batteries to meet that obligation. But as you bring on more batteries, that arbitrage shrinks, lowering your income. So therefore, you need to win on costs at that point, because the revenue numbers will start to decline. So it’s just a it’s a there are you know, there are assets that are getting built now that will make money. But if we built all the assets now at this cost, we will just have a high-cost system,

Gene Tunny  37:18

Right. Okay, yeah, good point.

Josh Stabler  37:21

And eventually that comes back because the customer the godly truths of our market is as the customer pays for everything. Yeah, everything has to be extracted from the end user.

Gene Tunny  37:31

Right. Okay. And what do you think about what the state governments here is proposing with? They’re looking at pumped hydro, aren’t they?

Josh Stabler  37:40

They are. So there’s some very, very large pumped storage hydro that they’re talking about. It’s gonna take a long time to get into the market. Yeah. pumped hydro is so when we’re talking about how solar drops in price, as we instal more pumped storage hydro increases every year, because it’s the civil project. It’s not getting smarter technology, its its its potential energy, gravity and height. That’s that maths still the same from 1950s, as it is, now it’s, we probably gained a couple of percents in efficiency. So we are we are getting more expensive, which is a problem, which is why the state’s doing it. Because the state can afford to do something like that, that has an 80 year life and take on that level of risk. Because the of the there are two outcomes, either it was not needed, and everything’s fine. And they’re happy with that, or it was needed, and they helped make it better. And they’re happy with that, as opposed to a private company, which would be unhappy with a scenario where they were unneeded. So iIt’s not that it’s warped. It’s just that they have greater vision in terms of what what is important to them compared to a private in private industry.

Gene Tunny  38:55

I liked the point you made about EVs and in just how many Wivenhoe dams the EVS could represent if Wivenhoe, Wivenhoe is not Hydro Electric is it?

Josh Stabler  39:06

It’s a pump storage. So it is a small drive to a big lake, okay, and it’s called split Creek. So it has the ability to move water up and down from the so an actual slide on the dam is not good for the power station, unfortunately. But it has about 20,000 mega litres of water. So it’s got a large area that it can fill. Yeah, this gives a you know, having all of those batteries gives a incredible capability to meet the rearrangement of data nine, right, we probably have too much, which means that we will, we’ll probably get to a situation where not everybody has to do it. Because we’ve got we’re going to have all these batteries and all these cars and we’re not expecting everybody to be doing this every night. We don’t expect you to get because the other problem is is that you have to fill during the day and then empty when you get home and your rooftop PV is on your roof and you’re not at home because you drove your car away. So if we’re imagining in 2040, we have an answer to that, which is when the car drops you off, it goes home again, because there’s an automated car, and it returns to the base and fills up. And then it comes and picks you up in the afternoon in the process, it’s filled. And when it arrives, it pumps power into the grid, and keeps everything’s sorted. Because it’s moving energy around, not just passengers.

Tim Hughes  40:24

I see this feeds into an area, which I think is really interesting, because the technology is moving so quickly. Yeah. Is that then a hindrance to adopting new technology because you know, you’re investing in infrastructure that all of a sudden becomes, you know, it gets superseded by the next shiny thing.

Josh Stabler  40:40

Oh yeah, especially big costs, like a great example is distribution networks, you’ve got these power grids, or these power lines, they are long, long, long life assets. But if you’ve got power that’s moving by car, you don’t need the distribution network anymore. You got this. So which leads you to the threat, which is known as a death spiral, which is that you have a large cost, but by structure, and you’re smearing it over customers that are getting smaller, which means that you need to charge them more. So eventually, we’re in a position where my, my mom needs to pay $250 million a year in order to keep everything on track. So because you know, it’s the last people obviously, regressive, the people with the most money exit first, and the people the least money exit last. And that means that you’re smearing more and more customers, people who can’t afford it. But that just leads you and that could be where we’re at, we could have some of these assets that are built that are a little bit stranded. But again, you know, some of these things need to get done. In order for us to get there,

Tim Hughes  41:41

You end up with a drawer full of Betamax videos and CDs.

Gene Tunny  41:46

This is fascinating. I’ve never, I hadn’t thought of that before. But if I’m interpreting what you’re saying correctly, we’ve got a car that drives us to work, it’s all automatic. And then it drops us off, and it goes home. So we have all these empty cars travelling on the roads to go home, so that they home when the solar PV is collecting the energy, and they’re storing it.

Josh Stabler  42:12

Yeah. Do you want to make it’s really crazy? They may not go back to your house.

Tim Hughes  42:15

I was gonna, I was going to say they go to the closest available home. Yes, you know, but the thing is also like so this, I mean, we’re getting into the speculative nature of this.

Gene Tunny  42:27

Imagine the IT or the AI  that you need to organise all of it.

Tim Hughes  42:31

That is an exercise in efficiency. Yeah,

Josh Stabler  42:34

well, that’s, that’s the classic, I’m travelling salesman issue. So you got to got all these ones that you need to move on. Because once they select does, it does the first person who gets to choose it, because I’ll just choose the one next door for the next 17 years right now. So that it doesn’t every time. But you need to make sure that that is an equitable sort of delivery of energy. And when we get to that state, then, you know, if you’ve got this demand that can be moved, and can be selected as selective and discretionary in its consumption, then we can just keep on installing more solar, because it will find a find somebody who wants to buy because the power all the cars will come and fill it up. Which leads us then to a problem, which is what have we just built the world’s most expensive way of doing that. Because most of our energy that we need to have, we need to move from the middle of the day to the evening. If I put power into a car, I can come back 100 days later, and it’s still at 99%. So long as you don’t put on a sentry mode, then it will consume it all. But you got to you’ve got to technology, a wonderful technology that is able to keep this energy for long periods of time. But in fact, we don’t need wonderful technology, we need terrible technology that is highly inefficient. That just does it for nothing between the middle of the day and evening peak. And then we can just keep on plunking down more and more solar, because it’s going to solve the more and more expensive evening peak with gas issues or any other thing else or its competition is expensive other vehicles or other batteries. And you’re just trying to undercut them by buying for nothing and selling for anything.

Tim Hughes  44:11

So becomes a market sort of battleground if you like,

Josh Stabler  44:15

Well, I think we’ve over engineered the solution. We’ve there’s probably a much cheaper, easier, stupid engineering solution.

Gene Tunny  44:22

So what and what is that job?

Josh Stabler  44:23

One example would be let’s freeze ice and your roof and make your house cooled down when it does that. Now that one’s I’ve already been asked somebody I think it’s been debunked, but there are answers, which are to do with most of our most complicated times like today. We’re 37 degrees too hot and what we need to do is just move these copious amounts of sun because it’s hot, and it’s bright into the evening and just make cold and if we make it cold if you make the house cold, like in Germany, you have pipes throughout the house and you just heat up that and that hits that water heating keeps the house warm. Same thing We just need to know, is that economically viable? Do you need to go to every single house and water? You know, there are, these things start getting highly complicated when you start thinking about all the engineering and and there’s just a point of, we kind of don’t know what we are going to have. I can think of 25 ideas today on what could possibly happen. And none of them will be right in comparison to what we’re going to do. 20 years time is a long, long time, in a world where people are incentivized to reduce their costs, where something starts causing, you know, the old adage, high prices as a cure for high prices. Because when it starts getting up, people start finding different answers, they find, oh, I don’t need to use that much electricity, I can lower my consumption, I can make these changes. And once you start having those drives, correct drivers people follow, follow the economic behaviour, we, we underestimate our citizens. And that’s why we make our electricity tariffs so simple, in terms of the way that they’re done, the billings insane. But the actual methodology is very, is too simple. It’s, you have a flat price from 7am till 10pm at night, even though that you don’t consume that way anymore, because most people have solar, which means you don’t consume during the day, and then you consume a lot during evening. So we actually need more definition that will drive behaviour, if you were aware that these things were driving you and changing your behaviour, then you would do things slightly different. Anyway, that was it’s a nice little.

Tim Hughes  46:29

It is interesting, because, again, it’s an it’s a question of efficiency. Yeah. And yeah, and householders are interested in efficiency, especially when it’s gonna save them money, especially when it’s gonna save them money. I did have another thing I wanted to pop in there, because I don’t want to make it too speculative. Because I mean, it is fascinating. But solid state battery technology has been mentioned by a mutual friend of ours who John Atkins, who was on a previous show, previous episode. And he had come across this technology, I think Toyota are one of the leaders with this new battery technology, which ultimately could have the potential to charge your house. So it’s not just running the car, you can then plug it back into your house, and it can run the house in the evening. So one of the main areas of concern if you like, at the moment, obviously, it’s you can’t take a punt on future technology that’s not here, we have to go with what’s here. But this must be also a concern for not a concern. But like, governments aren’t always going to be the first to adopt this new technology. But it must make it harder for them to commit to putting infrastructure in for a technology that they think could be redundant fairly soon.

Josh Stabler  47:42

Yeah, and that’s where, you know, a lot of the res idea is that we’ve we have this expectation that we’re going to need large scale wind and solar, out in the out in the regions, that’s going to bring all the power in and that and therefore that’s where the energy is going to come from. And the biggest error in any of the forecasting for the last 20 years of electricity has been the forecast of rooftop solar, every one of them is like this year, it’s gonna be the same as next year quadruples. This year, it’s gonna be the same instead of quadruples, there’s just been this constant misunderstanding of how quickly people were going to invest in it. And they’ve and the and the forecasts have been just horrendously wrong. And now, rooftop solar as a market share is one of the biggest in the net, it is got a now a major part of the electricity grid is what happens from rooftops. And that is driven by mums and dads.

Tim Hughes  48:40

The market is driving this as we’ve had conversations with quite a few different people. And the common thread is that the market is driving these changes.

Josh Stabler  48:48

It is but do you get to talk? Do you get to go into the room and tell people that you’re going to go and do this? Are you going to tell people that you’re putting batteries in, or the big guys can? It’s easy. There’s only like 100 of them, we just go and ask them are you going to go and install batteries and they say sure, I’ve got this big plan to build this big battery out there. And I’m gonna build this wind fine over there. And this is where my solar farm is going to go. And they can tell the people who are going to make those plans. What it is, they didn’t go and interview 15 million households to find out who’s going to invest in batteries. So there’s a level of a lack of advocation on behalf of those customers on behalf of mums and dads in terms of what they’re going to do. They also don’t really get paid for it. Because when they installed batteries, they lowered the consumption during the middle of the day. For the first 10-15 years of this market. The middle of the day was the most dangerous part. It was the most worrying section was what’s going to happen at the hottest point of the day, two o’clock in the day. It’s the highest demand we have the hottest weather and the electricity grid starts failing power lines can’t move anything. And then we don’t have that problem. Because rooftop solar has completely carved out the amount of demand we have at what used to be the most threatening. Now we’ve built, the whole market has built all sorts of power lines, and extra things that need to handle hot weather to move really long, lots of power at certain points in time, that are completely unused now, because that requirement doesn’t exist. And then when we start thinking about what’s going to happen with people, when they put vehicle to grid, and they can move their own power between themselves, Well, no one’s getting asked. So we don’t know what they’re going to do. So there’s like a just an unknown when that starts happening. And what I suspect is going to happen is that eventually, a, someone like probably Macquarie Bank, because they’re the kind of people who would do it, which is they’ll work out that if they install a battery on your home loan, you are now better, you are now a better creditworthy person, because your costs have just gone down, so they can offer you a better deal. And at that point, it all starts changing when you can just put on your home loan.

Gene Tunny  50:49

Right? So you can buy a Tesla Powerwall.

Josh Stabler  50:52

Put it on your home, you are now you are now considered a bit less of a threat, because you don’t have an electricity bill anymore. So at that point, they’re like, oh, okay, well, yeah, you deserve to be I can, I loan you money if you know, whatever percentage lowest because I think that you’re in a better, better position. And you can put that money on to your on your home loan, and we’re going to accept that. And that’s all fine, because we consider this an investment, not a bad, not a negative decision. Once that starts happening, things start moving quickly. Once debt gets involved, the world moves changes very fast.

Tim Hughes  51:24

Yeah. And that technology is obviously good for a considerable time to come. Solar seems to be working really well, that 40% drop in six years that you mentioned down to renewables. Great news. Yep.

Gene Tunny  51:39

Yeah. Okay, so, Tim, I think we suspected we, we might be picking Josh’s brain a lot, we’d go on quite a while. So we’re at 50 minutes, I’ve got a few questions I want to make sure we get answered before we wrap up. So if I try and wrap up for the next 10 minutes or so. Okay, so first, what about nuclear or hydrogen? How much potential do they have in the future electricity grid?

Josh Stabler  52:07

In the world nukes have a very big role, in Australia. I think that that the moment, most of the discussion that is around nukes is probably not in good faith. It’s more in a let’s stop doing things and wait for this new technology. And then our didn’t work out? Well, you might as well stay with coal. I don’t feel like the discussion is necessarily in a in a with completely good faith. Your issue with nukes, which is the same ones that you have with coal is that you can’t get cheaper than solar in the middle of the day, when it’s delivered to your house on your roof. It is cutting through transmission distribution directly into the source of where the demand is, which means that is impossible to get cheaper. So that means that nukes will never be able to run 100% capacity factor, because they will be carved out by the six hours of sun every day, which means that their capacity factors will be lower, which means that their very, very high capital costs will have to be smeared over a smaller volume making their costs, every estimate of costs will be based on 100% capacity factor. That’s all impossible, which means that everything’s going to be more expensive than you anticipated, unless they plan on turning off solar. So they need to get rid of a better solution to make this other one work. So I just don’t see it really working on hydrogen. I am the biggest issue with hydrogen is economics. And it is an inefficient process to produce energy that can be moved. Now, if we have infinite free energy in the middle of the day, because we have so much solar, then having something that costs nothing to put into this energy. So if it’s inefficient, inefficiency doesn’t matter when it doesn’t cost you anything. Zero times by an efficiency of 30% is still $0. So so long as you can get to a point where there’s basic never ending spilling of the load of the solar that it would do nothing, it would literally be turned down and dig and shorted, then you’ve got something that can make sense there. Because then you can just the inefficiency doesn’t matter. So that’s what I was talking about before we you know, we have what is our engineering solution? I mean, that one there is a horrendously inefficient way of getting energy. I don’t know you might fit the bill. I it just doesn’t fit the bill now. Yeah, because the cost structures are $2 or $2 a kilo. That’s $15. If you could do, we’re not doing anything at $2 a kilogramme. Right now we’re doing things at six and sevens. We’re talking 80s and $90. A Giga Joule, you know, we’re having conniptions right now, because the gas prices are above $12. We, we can’t expect to move from something where the world goes in goes into crisis mode at the best possible price point of the future. Like that’s there’s there’s a there’s an issue there. So we’ve got to work out how we’re going to bring the capital cost down and then the marginal cost down so that the the dollars per kilogramme that was a giga Joule for hydrogen falls. But even with all of that, I don’t see how it beats EVs, like, how does it be just putting the power directly from the roof into your car? Like why introduced another thing between an inefficient thing in between there. So if you lose that market, you don’t have EVs are okay, maybe you’re going to get car trucks, because they might need the energy, well, there’s probably better answers to that one as well, why not just have replaceable batteries in your truck, because then you can just take it out, and then you don’t have the energy problem, you can just put a new one in moving energy to other countries so that they can use it that very much relies on the demand, wanting to pay more for it. We’re not, we’re not in charge of that. Japan’s in charge of that. And Toyota most recently, sort of can’t there or not can but they’ve di D prioritise their hydrogen cars, which is not necessarily a great sign for where that’s going. But there are other things green, green steel, you know, there’s always other things, there’s always other things that use hydrogen and making that green. Sure, that doesn’t seem to that seems like a great direction, because you need to build it anyway. Need to get the hydrogen somehow anyway. And your choices are using natural gas or using clean options. If your carbon has got a price on it, then you will end up with a clean one. Without a price. You need regulation to say you can’t do it that way in order for it to hurt. So that’s, that’s my concern is just it’s just economics. That’s that that’s worries me there. I just needs to get the economics. You know, the numbers are so big that it needs to be like have like, eight times. And things can get hacked. It’s easy, you do a lot of economies of scale, and suddenly you find something that’s half the price. But doing it eight times feels like a lot of steps that you need to make better.

Gene Tunny  56:54

Yeah, here there,

Josh Stabler  56:55

you know, yes, you can get a couple if anything’s out by four to one. And its initial stages. Yeah, that’s, that won’t take any time to fix. But, you know, 100, to one that starts getting to a point where you’d like we, there’s a lot of things that need to go right together.

Gene Tunny  57:10

Okay, so now some policy questions and probably haven’t left enough time to go through these complex issues. I’d be interested in your thoughts on the you mentioned capacity, capacity markets before paying for capacity. So you talked about the problems that nuclear and coal, they can’t compete with solar during the middle of the day? Should we be paying to the generators, the fossil fuel generators, or if it’s nuclear, paying them to make sure that they’re online, that they stay in the market, that they’re available? If we need them? Is there a need for some payment like that? So that’s one policy question. The other big policy question at the moment is regarding the and the one of the challenges we’ve got, as this episode will be released after the national Cabinet meeting that we’re having this week to decide on whether we have a cap on coal prices, whether we have a cat isn’t it is proposing a cap on gas prices and also a domestic domestic gas reservation policy. What are your thoughts on all of those,

Josh Stabler  58:10

please start on the gas cap one and then go back to the GST. So the gas coal caps, your biggest issue with any type of so let me start with gas gas one because and they’re all good, we got analogue across to call it the gas, the problem with the gas market cap is that you need to you are having a broad based market response to try and solve what is not a broad based problem. So your businesses a an example a coal mine does not need cheap electricity, because it is making more money than it knows what to do with. So charging it more for charging it an appropriate price for electricity, based on its cost structures end up its revenue stream is part of the reason why cost structures are so high, which is why electricity is high. So if you give them a discount on their electricity, then they’re just making more money. If you are a services business, I’m sure electricity doesn’t even make it or a percentage number in terms of a normal business or normal professional services business. So increasing the cost of electricity doesn’t make a difference. It doesn’t materially change your market, your value of your business. It doesn’t materially change whether or not you’re viable. However, there are businesses that where there is a clear difference, which is if you are a domestically focused manufacturer, and you have a implication of high absolute prices will cause you to pass on high absolute prices to the domestic market that has an inflationary impact, and therefore it needs to that has a legitimate claim to being fixed and to being resolved. Your other group is that mums and dads have paid two points to Extra 2.9% of the total costs for the last 40 years on electricity might be slightly higher right now, but the number is about the same all the time. It’s also not a lot with it, our cost of living has increased remarkably much this year, because of interest rates, not because of electricity. So we’ve had a massive increase in terms of people’s livelihood costs, because of because of the interest rates. And electricity is like a thing that is annoying because it’s on top of so. So for depending on which sector of the market, if you are a low income earner, then that 2.6 is not 2.6 is probably four or five, because your consumption doesn’t really change that much based on your, you know, your your money, you still have to do all these things to keep the lights on and to consume. And therefore that becomes a regret your recess, regressive sort of threats. So you need to manage low income, and you need to manage domestically focused manufacturers or consumers, energy intensive consumers, if you are the rest, which is a lot of the energy consumption, aluminium spouses, you know, your fertilised and everybody else, they are competing internationally, and they are competing in a high market international price. And therefore, their prices they’re passing on, I’m not even going to Australians, they’re going out into the world. And the most of us not even coming back to Australia anyway. So what that doesn’t, so doing a broad based outcome for that kind of doesn’t really fit the bill. So I think that’s where the problem is. Now when you take a look at coal, coal really only has one market in in Australia, which is thermal electricity, our, our meteorological metrological cold, there was stuff that’s used for coking coal, we don’t, we don’t make steel in Australia anyway. So all that stuff is going off to China where the iron ore, it’s getting turned into steel. So there is the implications on the coal market are purely on the electricity space, so long as you can still get the energy. Our problem in winter was not because coal prices were high is because the coal generators were offline. And the ones that were online had limited coal supplies, and you couldn’t give them more coal, because they’re not next to the coal mine. The ones in New South Wales are off the spur of Newcastle and you need to drive the train through a major city to get it to a power station. And you can’t deliver any more to that power station. So you get physical limitations. And just simply saying, your price of your coal is cheaper, doesn’t make them have better power stations, or find more coal, they are just limited by their energy. And that makes it a that that’s an that could return next year, we could have kept on the market, low coal prices, and no energy. And therefore prices are high, because we’re not actually keeping anything that fundamentally keeps the market under control. So our threats right now are not only input, the problem that I find is that everybody said the market is going up because of Ukraine, which makes it feel like it’s an external thing. And all we have to do is disconnect ourselves from there, and it’s all fine. But we aren’t we aren’t actually we’re not we’re in we’re in our own scarcity issue domestically, at the same time as the scarcity issue internationally. And when it goes bad, it joins the international market, which makes it feel like it’s all related. But it’s actually just joining whether they’re in a bad place, and we’re in a bad place. And unless we see some sharp increase in availability, then we don’t, we may just have the same problems again. So that’s, and that leads us to our other question, which is what do you do about capacity markets? How do you make a power station that is unreliable, more reliable? One way, definitely making sure it goes to be less reliable, is to not spend any money on maintenance, so that it will turn off. So if you are thinking that your power station has two years left to live, you’re not going to spend any money on your maintenance, just like you don’t spend money on that car, a clunker that’s about to break down, you don’t go and send it in for a service. When it breaks down, you leave on the side of the road and get someone to deliver it to their records. That’s the problem we’ve got with the power stations as we’re getting to the record stage. When they break, like realistically This is at the point in their life where they might have four units, one breaks, it becomes parts, it doesn’t get turned back into service, it just left to make sure the other ones survived through to the end. Right. So that’s where your capacity might do is it might give you an incentive to stay around for a longer period. Yeah. Which gives you the money to be able to do that to spend on the maintenance so that you can have an asset that will be able to survive until you’re no longer required.

Gene Tunny  1:04:50

Yeah, so we’ve been talking about this for for years now. Do we know if we’re gonna get one capacity? Okay.

Josh Stabler  1:04:57

I think now that we’ve got So many power stations planning on exiting over the next X number of years. It’s also about with we’ve rapidly changed our expectations. Yeah, even just two years ago, we were in a position where coals wood, coal was cheap. There was coal mines were losing money on what they were delivering in. So they stopped slowly stopped there, the supply, you had power stations that weren’t making money, because they were they weren’t, the electricity prices were so low, you know, we’ve, we have gone from $30 a megawatt hour to $300 a megawatt hour in two years. Like it’s such a variation in terms of the outcomes, it’s so quick that nobody has in a market that that builds its world over 10 years, you can’t respond in two. And, and that’s just where we’re, you know, when we’re, you know, we go into a price cap on gas on coal, it doesn’t fundamentally make doesn’t change the engineering just changes the economics. And then the hope is that the economics works. Because if, if you’re saying that’s the next year, anybody who sells coal only gets a lower price, then you just hold and you own it, and you have a stockpile of coal, well, then you just wait to the year after and some of the higher price economic theory is you just waiting there. Or if you can deliver to a boat and sell into $500 a time overseas, then you definitely do that. So you’re definitely getting this position where if you deflate the domestic one, you also need to motivate them to continue to supply because otherwise, you’ve just given them the exact opposite, which they don’t supply, because no one’s going to pay you anything that’s worth anything.

Gene Tunny  1:06:35

Yeah, well, I mean, is that what we’re going to end up with? If there’s a domestic gas reservation policy, where we say that you’ve got to supply this amount of gas to the domestic market at this price, I mean, is that where we’re heading,

Josh Stabler  1:06:49

it does appear that that’s where the direction they’re going. It it. The problem also applies to where that supply is coming from Australia is a lot the tyranny of distance. We with this usually said in the fact that it takes a long way to deliver things from Australia to other countries. But the tyranny of distance also works for our large country to deliver gas from Dolby to Moomba, to young to Melbourne is 2800 kilometres, yeah, which is the same distance as Edinburgh to Turkey. Yeah. So it’s very long distance in terms of of how far you have to deliver, which means that we don’t necessarily have the infrastructure to be able to deliver all the guests that’s required in the south via the infrastructure that we have we we have limitations on that, which means that we need to build up our, our storage in the south ahead of winter so that we can actually deliver it. Now if there’s a cap on the market. And it costs you $12 To buy gas, and it cost you money to put into storage so that you can take it out and get paid $12 What was the financial incentive there? So your cost $12? And then you get paid 12? So what are the $2? Or you just lost that? Okay, well, once if I deliver it from Queensland, where you buy it at two or $5, you’d paid $3 to deliver it down, and then you can sell it for $12. So you’re taking a financial hit there as well. So you, it’s not just so simple as to say that everything’s the same, because then you’ve got no incentive to do anything. If you’ve got gas in Queensland, and you’ve got no reason to move it to another region, other than regulation, that you must deliver excess capacity. It’s just this is when you start delving into how you want things to work. It’s the the problem with putting a cap in is you lose merit, or you lose who deserves to get the gas, who’s willing to pay more who’s willing, or has a higher need for that. So they can actually meet that meet their requirements. Because you don’t have the merit order, you then don’t have the volumetric assessment. So if I was somebody there, I’m just going to say, Can I have a billion petajoules of gas. And if we prorate or down, I’ll have 99.9% of it all, because I asked for the most amount, because there’s no difference between my $12 and your $12. Let’s just split it, split it down the middle of who bet in a billion versus one. I’ll have my billion and you can have your lunch. So it’s it just your problem. You’ve it’s there’s a lot of unintended consequences that need to be managed there. And it’s it’s difficult. It seems simple, but it’s difficult.

Tim Hughes  1:09:33

Yeah. Does that fall into the category of the infrastructure needed for that particular energy source? So for instance, you know, it’s obviously going to be expensive to deliver that, that amount of gas. One of the things I was going to say it was like clearly, not clearly, but it would appear that a diverse array of energy sources would be a wise thing to do. So we now have all of our eggs in one basket Solar has its limitations. Wind has its limitations, etc. Coal has its limitation has its limitations and gas has its limitations as you were saying there’s so like, a sort of array of all of these solutions that would get us towards Net Zero. Yep. would seem like a good idea. So hydro might be a good part of that.

Josh Stabler  1:10:21

Or we should definitely have every single piece of the puzzle that we can get, then the question I think has been slipping in regarding the Niccolo answer. The problem with the nuclear answer is there’s no way we’re getting a nuclear facility in, in Australia. 15 years. Yeah. So even even, you know, we can even have the conversation just so long as the conversation isn’t, we should spend more time talking about Nikola the, the the reality is, if somebody wants to go and do that, yeah, change the law, and then have somebody go and pay the money and spend the 15 years getting it organised. Talking about it now, and with it never been within, you know, not five election cycles away. That’s, that’s, that’s a long, long time. Now, and I guess that also leads to how quickly things have changed away from what we expected, our expectation of gas was that it was going to do nothing anymore, we were just going to have a little bit in Victoria, it’s expected to continue to decline every year, the gas storage two years ago, almost did nothing. The amount of gas that we should be expecting, you know, we, we ran near record levels during winter, but we ran an absolute record lows during spring. So that’s, you know, that’s like a 10 to one variation in terms of daily consumption between spring and winter. We’ve got this, it’s, it’s not just that we have a, an, a constant need is this we have this massive variations and our experts, the forecasts, then beforehand, were like, we’ll use 22 petajoules. And we ended up using 100. Like, we’re completely, we’re completely misreading how it’s going to occur, because things happen that we didn’t expect. And those unexpected things relied on certain technologies to solve it. Because you can’t ask solar to be brighter. You can’t ask wind to get more wind it, it can do everything it does, which it what it does, it does, it runs as hard as it possibly can. The problem with that part as possibly can is, is you can’t go more and go less solar conquer more can only carry less. Gas is already less, and it can do more. But our complication of that is that ends up costing money. Now that might be the cheapest money we could spent. Like that might have cost us a lot of money. And we managed to have no shortfalls. And we managed to keep society going on. And we had no other issues other than a whole lot of political noise around the outside of it. But in reality, we only had a small, very small marginal change in terms of people’s bills. And everything’s, you know, some people are bad, but you know, in general, we have worked our way through it. That cost us money. Yeah, could have been the cheapest option we had available, probably was the cheapest option we had available.

Gene Tunny  1:12:56

Right? I think we might have to.

Tim Hughes  1:12:59

It’s quite an it’s so good hearing your insights and your your from your experience, Josh. And, you know, we could go on and on.

Gene Tunny  1:13:11

I think we’ll have to have you back on again, Josh, because I need to digest. Yeah, this episode. And what’s what’s been said here, because there’s a lot of, there are many things to think about. And I mean, I’m starting to think oh, yeah, I mean, there could be some things that are really positive and make it easy. But then there are other things that are big challenges. And, and you mentioned how this is all uncoordinated. And yeah, I mean, it sounds to me like there’s a risk of some bad outcomes in the next decade or so potentially the non trivial probabilities of, of blackouts. And it just, I mean, I guess we will muddle through somehow. But could could be messy.

Tim Hughes  1:13:54

We seem to be doing remarkably well, like that. The figures you mentioned about reducing 40% In six years is is fantastic. Yep. And I was going to mention, of course, like, there’s a geographical advantage that we have in Australia, for instance, like with solar, like the other parts of the world. Yeah, they would love it doesn’t have, you know, I said so they might have different nuclear might be more viable for certain places, with all its, you know, issues that come with that too. But certainly as technology and this emerging technology, which is coming through very fast, you know, if they can get solar through to be doubly triply 10 times more effective, then it can make it more viable for different parts of the world. So it’s, it’s fascinating, where we’re going and it’s it’s amazing to move so fast. And I guess this transitional period that we’re in is really important that we not trip ourselves up. Yeah, on the way to net zero like, which, of course, you know, who wouldn’t want to be there? I certainly wanted to be there. But we want to get there with the lights on.

Josh Stabler  1:14:59

Yeah, we need to do it. with the least amount of, you know, this is an essential service. Yeah. And it, you know, society doesn’t function if this if this breaks and and transition will lose its lose its losers backing if it can’t keep the lights on. So it’s these are these are important parts. But it’s also I have one last point which is always very difficult to imagine the world different to the one you’re in. So right now we’re in a high market pricing, we’ve got all these danger, we’ve got all these conditions that are that are creating uncertainty where we are, but we have so much, you know, it can change so quickly in this space, we’ll just two years ago, we’re in 1/10 of the price. Yeah. And it can move very quickly against you in or not against you, but in very quickly into a different environment. And it you know, leaps of faith could leaps of technology change, or, you know, we could have, like, everything that’s basically happened in the last couple of years has been supply side failure, it’s just been everything that happened just happened to be on the supply side, we didn’t have a smelter go down. We didn’t have customers do large scale production, because they got their meeting, you know it the spot price was high. But domestically, they’re probably making pretty good positions that are able to pass on these costs. That’s why we’ve got such high inflation, these things are happening, which is allowing people to survive. But if these if we suddenly got lucky on the supply side, and things started getting better, and some things just started getting lucky, you know, we could really move that back away, and then we could leave the international space where it is solve our domestic scarcity issue. And then it won’t be Ukraine that’s holding us up, we were in, we’re in a we can return back to a a more settled environment, which is a little bit like the US us as far as you could your gas, because they are separated for physically separated and the ability to export more is not there. If we suddenly solve some of these problems, we can really pull back, we don’t use other gas for electricity, and that won’t set the price. And therefore we can see it dropping back down if we see some of these problems get resolved. So it’s just a, you know, it’s easy to be stuck in it and to feel the you know, the shadows, the darkness of the shadows in the times when they’re in there. But it’s also you can move past that and you know, we’re definitely at 40% down in emissions, we are on the right path and once we start bringing EVs that’s 54% of the emissions in two sectors, and if we can bring them down to full 4% That’s a long way in terms of where we want to go.

Tim Hughes  1:17:31

Well, I was gonna say I mean, because the way this is driven by the market is, is giving it is decentralising in its effective, like, yeah, if you’ve got rooftop solar, and ultimately you can be self sufficient. The consumers have more autonomy and, and that collectively around the world will make a massive difference. And so it’s, it’s a good direction, it appears, you know, like, I mean, who wouldn’t be happy with that, because you’re not going to have the bigger issues with those outages, you know, it’s going to be more of a localised

Josh Stabler  1:18:04

issue, and a 5% fault is 5% of a million, which makes it 50,000. It’s, it’s not 5% of 20. When you start becoming actually 5% means it’s probably those two, all which is probably the 1% of the time is four off, it’s like when it’s a million, it’s always the same, it’s you know, it’s distributed, the the law of large numbers kicks in, and it’s just 5% Haircut across all the time, on everything, as opposed to occasionally being a very large number, which is what we’ve had very large numbers of times where we’ve had coal fail at the same time as coal fail, same time with gas fail and the, in the in the misalignment of a couple of bad things at the same time, because they’re large, ends up creating large impacts. Lots of little ones and it all disappears.

Gene Tunny  1:18:54

Okay, Josh table, it’s been fascinating. Thanks so much for your time and for your insights have really appreciated that. And once we digest this and think about some more, I’m gonna have to chat with you again, since it’s been terrific. Thank you. Thanks, Josh. Thank you. Okay, so what are the big takeaways from our conversation with Josh? My first takeaway is that the transition to net zero will probably be a bumpy ride. I love the way that Josh described it. To quote Josh, the complication of transition is that it is by default, disorderly. my conversation with Josh confirmed my fear that we could end up with unreliable electricity in coming years. I’m still very concerned, we will have to start expecting the occasional blackout as we bring more renewable energy into the system. My second takeaway from the conversation is that the energy solutions of the future may not be obvious to us at the moment. We need to allow innovation and we need the right incentives in place. EVS could be a big part of the transition path in the conversation with jasha was blown away by the idea of self driving EVs returning home or going to other people’s homes to fill their batteries during the day after they drop us off at work. That’s just incredible. Okay, before I leave, I should note that the Australian Government legislated a highly interventionist energy market package earlier this week, I recorded this conversation with Josh last week when we only had an outline of what could be included in that package. I’ll aim to have a closer look at the specifics of the package in a future episode. Thanks for listening. Okay, that’s the end of this episode of economics explored. I hope you enjoyed it.

The Aussie electricity market malfunction of June 2022 – EP156

Australia’s National Electricity Market was suspended by the market operator for nine days in June 2022. For a brief period, authorities were worried there would have to be widespread blackouts to balance supply and demand. In this episode, Andrew Murdoch, Managing Director of Arche Energy, explains what went wrong in June, and he talks to show host Gene Tunny about whether it could happen again. Are renewables coming into the system too quickly? What’s happening with batteries? Will Australia be able to cope with the retirement of coal-fired power stations? And what about all the EVs that will need charging? These and other questions are tackled in a frank and fearless conversation.

Coming up on economics explored…

Andrew Murdoch  00:01

Reflecting on the events of June, more energy would have been handy. So it was the cost of energy issue that created these extreme prices. So whether that energy came from renewables or from gas or from coal, any additional gigajoules or megawatt hours generated onto the system would have had downward pressure on prices and certainly would have helped.

Gene Tunny  00:26

Welcome to the economics explored podcast, a frank and fearless exploration of important economic issues. I’m your host gene Tunny. I’m a professional economist based in Brisbane, Australia, and I’m a former Australian Treasury official. This is episode 156 on Australia’s national electricity market, the NEM. In June 2022, the NEM was suspended by the market operator for nine days. For a brief period, authorities were worried there would have to be widespread blackouts to balance supply and demand. My guest this episode explains what went wrong in June, and we talk about whether it could happen again. My guest is Andrew Murdock, Managing Director of RK energy, a Brisbane based consulting firm specialising in energy projects. Andrew has a background in engineering, and he really knows what he’s talking about when it comes to electricity. So standby for a deep dive into Australia’s NEM. Please check out the show notes relevant links Information and for details of how you can get in touch. Please let me know what you think about what either Andrew or I have to say. I’d love to hear from you right now for my conversation with Andrew Murdock on the NEM. And we also chat briefly about electric vehicles toward the end of the conversation. Thanks to my audio engineer Josh Crotts for his assistance in producing this episode. I hope you enjoy it. Andrew Murdoch for a market energy. Thanks for coming on to the programme. Thanks, Jane.

Andrew Murdoch  01:55

Good to be here.

Gene Tunny  01:56

Yes. Great to have you on. So you got in touch after a recent episode where I was talking about EVs and I mentioned that you really love to talk to someone who’s familiar with energy with electricity. And you got in touch and yeah, it seems like you’ve got a great track record. Great experience. Could you tell us about what Arche Energy does and your experience, please?

Andrew Murdoch  02:22

Yeah, sure. So Arche Energy is an energy advisory firm. We’re a small firm based here in Brisbane, Australia. We help people develop energy projects, we help people solve strategic energy related problems. We help people with decarbonisation and developing strategies to meet their netzero goals or other other related goals. We do project management, project development, strategic engineering, owners engineering, etc, in the energy and infrastructure industry.

Gene Tunny  02:54

Right. So in terms of meeting their decarbonisation goals, are you advising them about what renewable energy options they’ve got? I mean, what sort of things would you be advising them?

Andrew Murdoch  03:06

Yeah, absolutely. So I guess a typical decarbonisation job will be a for us will be an industrial mining facility with a significant energy consumption need. And we will look at what what their energy consumptions is, what their, what their physical processes are, and look for opportunities to either make better use of the resources that they’re using, whether that’s gas, coal, heat, power, etc. And then also look at opportunities for integrating renewables and other low carbon sources of energy into their into their processes.

Gene Tunny  03:45

Right. Okay. Are there any examples of clients you can talk about or jobs you’ve done?

Andrew Murdoch  03:51

Yeah, so one particular job was a mining clients, they they developing a greenfield mine, lithium mine over in Western Australia, they guessed the way that you would power a mine 20 years ago was when you would just get a half a dozen big diesel generators, truck diesel, the site and the way you go. These days, you look at some more complicated, complicated processes. So you might integrate some solar into the into the system, you might, you might also integrate some wind into the system and certainly batteries are very valuable for mine supplies. Mine power supply systems now because it allows you to if it allows you to run your engines more efficiently, allows you to have less engines and allows you to deal with shocks to the energy system when a cloud goes over your solar farm or the wind stops blowing etc. So those technologies that are available now are we’re seeing those in most mine supply power jobs that we’re doing these days, right

Gene Tunny  04:56

but would you typically have some diesel generators, they’re just in case.

Andrew Murdoch  05:02

Yes. So system has to be robust enough to deal with a wet week or a week without rain, when the batteries can’t recharge, nighttime evening peaks, etc. So, but we’re seeing, you know, we’re seeing in the studies we’re doing these days, we’re seeing renewable energy fractions going up to sort of the 60s and 70 percents, which is, which is fantastic and wouldn’t have been achievable 20 years ago on mine sites.

Gene Tunny  05:27

Wow, that’s incredible. Okay, that’s, that’s good to know. We want to want to chat about as this whole issue of integrating renewables into the system. And, look, there’s a lot of debate about this. And there are people who are very pro renewable. And I mean, I understand that we have to get there eventually we need to decarbonize. I mean, I’m not arguing against that. But one thing I’ve been concerned about is just just how not, are we doing it too quickly? I think that’s still that’s a legitimate question. What are the risks to the system? We had this situation earlier this year, when the Australian energy market operator had to intervene in the national electricity market? It because it looked like there were concerns about the reliability of supply. Could you tell us about that? What’s your take on what happened there, Andrew?

Andrew Murdoch  06:19

Sure, we might just rewind a little bit and start with a little bit about how the market works. And the physics involved. It’s an incredibly complex system, both physically and commercially. So what we have essentially is a market that needs to match supply and demand almost instantaneously. We have very, ah, it’s not possible to store electricity as electricity. So even batteries are chemical storage, not not, not electrical storage. And so there’s a constant need to match supply and demand as accurately as we can. When demand exceeds supply frequency goes down, everything starts spinning a little bit slower. And when supply exceeds demand, the opposite happens. Everything speeds up a little bit. So there’s a constant need to match supply and demand.

Gene Tunny  07:09

Right? So I mean, what does this mean? Could this mean that it could damage some of our equipment, our appliances connected to the grid,

Andrew Murdoch  07:17

The system in Australia is very, it’s very geographically dispersed. We have power stations that are in the regions. And we have centralised demand in the major cities, capital cities, and also industrial cities like Gladstone, Newcastle, Illawarra, for example. And we need to manage the flows between the generation sources and the loads without overloading a particular network elements. So if we get too much power trying to flow through a particular part of the network, then we start to melt things. And so the market has to manage that. The national electricity market, the NEM, was established just over 20 years ago. And so, it, it has the objective of supplying power in the most economically efficient way to the consumer. Yeah, without breaching any of the technical constraints that it has to work with. So NEMO, the Australian electricity market operator operates a dispatch engine and the name dispatch engine. And that dispatch engine takes bids from each of the generators, builds a bid stack for each of them, and each of the each of the NEM zones, and the NEM zones roughly correlate to each of the states. And then that dispatching engine matches supply and demand and sets a marginal price based upon where the supply demand curve crosses,

Gene Tunny  08:45

Right. So this bid stack, your ranking the bids that come in, so see us energy or whatever, or the other generators say we will supply, what is the bid in terms of is it megawatts? Yeah, megawatts over whatever, particular period?

Andrew Murdoch  09:01

Yeah. So the unit of sale is megawatt hour, so that megawatt hour, one megawatt for an hour. But the bids are done on the bids are done every five minutes on a megawatt basis.

Gene Tunny  09:13

We will supply this much electricity at this price, correct? Gotcha.

Andrew Murdoch  09:19

And then the price is then set at the marginal, the marginal, the marginal bidders price, and everyone, everyone who gets everyone who bids below the marginal bidders price gets dispatched, and they and they they receive that price modified by their loss factor. And then anyone who bids over that price, then doesn’t get dispatched.

Gene Tunny  09:37

Okay, so it’s the marginal bidders price. So that’s the price that was offered by the bidder that they need the last bidder, the marginal bidder, to make sure that the supply of energy matches the demand. Correct? Yeah. Okay. Gotcha. And so everyone, all of the energy supplied, up to there that all gets the market price.

Andrew Murdoch  10:06

Correct. Now the bidders can bid anywhere between negative $1,000 and $15,100 per megawatt hour. So there’s quite a large range of permissible bids. Yeah, the reason for the negative bids is so that if you’re a thermal unit, a coal plant, you have a large cost associated with coming offline. And coming back online, so you will accept for short periods, you’ll accept the cost of having to stay on and receive negative prices for your power. The purpose for the extremely high prices are there to provide an economic incentive to construct peaking plants. So, peaking plant might be something like a gas turbine that only runs maybe 2% of the Year, 3% of the year. So it needs those extreme prices to be able to cover its costs for the rest of the year when it’s simply on standby. In parallel with the physical market, there’s also a contracting market, which is essentially an over the counter market where a generator and a retailer will enter into an agreement to swap exposure to the pool price. So essentially, they that’s what agreements that synthetically generates a fixed price netting out the generators exposure with the with the buyers, the buyers exposure. The larger gen-tailers also tend to vertically integrate as well to manage their risk.

Gene Tunny  11:28

So gen-tailers their generators and their retailers as well, because we’ve got this. Yeah, we’ve broken up the market in Australia, haven’t we? We’ve got we’ve split generators from distribution and from retailers. And once upon a time they were all integrated, weren’t they? We had these electricity boards. We had southeast Queensland electricity board, and yeah,

Andrew Murdoch  11:52

Yeah. So back in the 90s. Yeah, the, the industry deregulated and competition was introduced at a wholesale level. And now we have retailers competing for our, our, our, our retail contracts. And then we have the wholesalers competing to supply to the, to the retailers.

Gene Tunny  12:12

So Andrew, this is fascinating. We’ve got this complicated market, where there’s generators bidding into supply electricity at particular prices, and we’ve got these, this wide band over which they can bid and there’s a negative. There’s a possibility of negative bids. So that’s something we’re seeing more of lately, we’re seeing these negative prices. And that might strike people as very strange, why we see negative prices. So we’re going to just sort of chat about that in a minute. But also, you mentioned that it could go up to what was it $15,000 a megawatt hour. But what happened recently was that they said no bids over what was it? $300 a megawatt hour?

Andrew Murdoch  12:52

Yeah, that’s That’s correct. That’s correct. So I might I might go through what happened in early June. Yeah, fascinating. It’s a fascinating story. So so it all, it all began when Russia was demanding payment for their gas in rubles, and that shell and Orsted and others refused to comply and Russia then made significant cuts to gas supply into Europe, which then obviously had an impact on the the global LNG prices. And because most of these cases of this gas is is connected to the LNG market through the the LNG plants in Gladstone. And we’ve seen netback prices on the East Coast go up as well. So if I reflect back to sort of 2011 2012, we had a spot price of gas that was largely following the cost of supply around $5, $6, $7 dollars a gigajoule. In in March, sorry, in June, we saw prices ranging from between $15 and $43. A Giga Joule for gas, so quite a significant increase over the over the cost of supply for for gas on the East Coast. Right. So

Gene Tunny  13:59

we’re talking many multiples of cost of supply and multiples of many multiples of what it was trading at previously.

Andrew Murdoch  14:06

Correct. Yeah, right. Meanwhile, we had a very wet summer, and that wet summer had the impact of restricting coal supply. So for example, Millmerran wasn’t able to mined coal for a significant period, period of time. And global coal prices also followed energy prices upwards which coal difficult to get and expensive. So last time I checked, thermal coal was trading at around $400 a tonne, which is which is incredible. Now concurrent with that, we had a third factor which was that a large number of plant was out of service throughout, throughout the country. So we had outages that are raring Bayswater, Loyang Liddell and keloid Sea. See, I believe there’s also an outage, just one vacay at the same time as well. So that was about 30% of the call fleet was out of service in in in June. So we do have significant capacity be taken out of the market.

Gene Tunny  15:01

So one thing that’s brought up and I don’t know, I should be careful not to necessarily attribute this to Matt Canavan because I’ve had Matt on the show before Matt, someone I chat with from time to time about these issues. And I’m hoping to get him on the programme again. But it may have been Matt that said that, look, they’re just not investing in this old coal fired power generation, because there’s a push to decarbonize. There’s all of this excitement about renewables, and they’re not doing the maintenance, so they’re not refurbishing the old coal fired power generation capacity. Is that do you know if that’s true, or do you have any views on that?

Andrew Murdoch  15:39

I do have a view. And I guess I take the view that we’re currently using a lot of coal in the country. And it’s great to decarbonize, and it’s great to reduce our reliance on coal, but it’s not going to happen immediately. Yeah. And my personal view is that there was a lot of decarbonisation to be gained simply by making coal plant more efficient, and more reliable. So I’m talking about things like, for example, reducing our reliance on Victorian lignite and transforming it that to higher quality Queensland black coal will have a significant impact on carbon emissions, just by the higher quality of the fuel being burned. The other thing we can do that is, in my view, an easy win is to transfer from 1960s 1970s subcritical technology to 2020 Ultra supercritical technology, or even better integrated combined cycle gas turbine technology.

Gene Tunny  16:38

What’s the difference? Is there an easy way to explain what the difference between those two different types of the whatever it is, it depends on its level of criticality or something

Andrew Murdoch  16:49

Subcritical versus super critical. So, So essentially, if you imagine a little paper wind turbine that you’ve made that in primary school, for example, and you blow on it, and it spins, now the harder you blow on it, the faster it will spin and the more energy that it takes. Yes. So essentially, what we’re trying to do in terms of making a steam turbine more efficient is to increase the pressure at the, at the steam turbine inlet. So essentially, the more energy we can put into the steam before it gets into the turbine, the more efficient the turbine will be. Now, the difference between subcritical and supercritical, interesting little point of physics is that subcritical boilers, the pressure is relatively low, and we we heat up and boil water, similar, similar to the way that the kettle works at home. We bought boiled water to make steam, a supercritical plant. So supercritical plants, there’s not a distinct boiling phase, we simply just heat it up, and it gets thinner and thinner. And that steam because it’s such high pressure has the properties of both a gas and a liquid at the same time. So okay, that’s so much. It’s not so much irrelevant to the physics of efficiency. It just has to do with how we designed the boiler and the steam processes.

Gene Tunny  18:09

Okay. So it’s good to know that, that this technology that came out of the 19th century or possibly even before it can be improved and yeah, okay. That’s good.

Andrew Murdoch  18:21

And then the other dimension to, to decarbonisation of coal generation is, is is carbon capture utilisation and, and storage. And my personal view, and I know, people have some very strong views on this, but my personal view is that there’s more to be gained in carbon capture and storage. Okay. Okay, good. Good. Yeah. So back to June. And I guess the next factor that we have to consider was that June was unusually cold. So we had the ninth of June, the low at Archerfield, was 7.9 degrees against the June mean of 11.8 degrees. So it’s not super cold, but just a little bit colder than usual. And that what that led for us all to do was at home turn on your air conditioners. And in Queensland, on the ninth of June, we reached a new record maximum demand for Q2, for quarter two of just over 8000 megawatts, which is 8.2%, higher than the ninth of June of 2021.

Gene Tunny  19:18

And was this the day that they were warning that they might have to restrict supply? They might have to be blackouts in some areas,

Andrew Murdoch  19:26

correct? Yeah. So that was when we got the loss of reserve notices from right. So and So. Yeah. So I guess moving to that. Obviously, as that demand supply balance started to started to move into, the into the zone of scarcity. The prices went up and hit the market cap of $15,100 per megawatt hour on a number of occasions. As I said, you know that that very high market cap isn’t for our current market design and necessary factor to encourage investment in peaking Last. However, there’s a, there’s a safeguard, there’s a bit of a safety valve on the on the on the system so that we’re not exposed to $15,000 a megawatt hour for too long. And that’s the cumulative price cap. So the cumulative price cap is just under $1.4 million. And that’s taken as the sum of the price in each of the five minute periods over the seven days preceding. So essentially what that does is it gives you a maximum exposure that, that, that that for, for energy buyers, and on the rationale that okay, you’ve had $15,000 for a little while, you’ve paid your operating costs for many years to come. That’s enough.

Gene Tunny  20:41

Yeah. So do we know? I mean, I don’t expect you to denote that I’ll be here. But do we know which was the plan? Or the bidder the marginal bidder? Do we know who was the marginal bidder and what they were bidding into? To meet the supply? Yeah, well, that showed to meet the demand to provide the supply.

Andrew Murdoch  20:59

So yeah, that’s publicly available information and can be achieved, can be obtained through an email. Now it changes for every five minute period. Yeah. Maybe a different person to tomorrow. So there is a lot of data to get through to to identify that. And yeah.

Gene Tunny  21:17

So sometimes, so sometimes it’ll be renewables will let in the during the day, and sometimes it’s coal, and sometimes it’s gas. Do we know?

Andrew Murdoch  21:23

Yeah, so typical, a typical day. So back when when energy prices were normal. Yeah, the marginal the marginal operator during the middle of the day would be either coal or renewables, depending upon depending upon how sunny it is or how windy it is. So on a, on a sunny, moderate day, in April or September, you might find that that solar is is is the marginal bidder, and they may be solar has a negative short run marginal cost, because every month for every megawatt hour of renewable energy that you produce, you also produce a large scale renewable energy generation certificate, which you can then sell for $30, $40, $50 a megawatt hour to to your retailer so that your retailer can meet their renewable energy target obligations. Or you might sell it to a customer who would like 100% Green Power, okay, so so they have a negative a negative short run marginal costs and can afford to operate with a negative spot price.

Gene Tunny  22:28

So they can bid into the NEM at a negative price so that they can sell that power, and then they get this certificate, which meant, so this is a subsidy from the government. Is this right?

Andrew Murdoch  22:41

It’s a subsidy from the energy consumer. So yeah, okay. So so our retailers are obligated to, to surrender a certain number of renewable energy certificates based upon our consumption. Yeah. And we obviously pay for that through, our through our electricity bills.

Gene Tunny  22:56

Gotcha. Yeah. Okay, that makes sense. Okay. Yep. Yep.

Andrew Murdoch  23:00

Then on a more moderate day, the coal plant will be the marginal, the marginal, bidder. Yeah. And they typically have a short run marginal cost in the order of anywhere between $15 and $30 per megawatt hour when the price is normal. Yeah, maybe not today. So then in the evening, you might see some of the gas plant come on. And again, sort of back to normal energy prices, they might have a short run marginal cost somewhere in the order of 80 to $100 a megawatt hour.

Gene Tunny  23:28

So we’ve got, we’ve got solar potentially bidding in negative, you’ve got coal coming in sort of at a you’re at a positive level, and then gas at a higher rate they’d be bidding in during the evening. Yep?

Andrew Murdoch  23:43

Correct. Yeah. So you’ve sort of got those natural price bands that fit around short run marginal costs. Now, then you can sort of add to that and elements of profit maximisation. So. So to actually obtain those high prices, you might not be all of your volume at your short run marginal cost, you might reserve some of that to try and encourage the price up a little bit higher. So yeah, so, essentially, yeah, your goal is profit maximisation. And if you’re, if you’re a gas plant, and you’ve got so many territories of gas to burn every evening, you’re going to try and bid them into the network at at at a at a price where essentially you, you’re going to use up all your gas for the maximum amount of revenue that you can possibly obtain in that evening.

Gene Tunny  24:33

Yeah, yeah. Okay. So they’re being strategic about when they bid into the market to maximise their profits and Okay, so if we go back to June so there was you talked about this cumulative price cap and did that kick in in June did it Yeah, correct.

Andrew Murdoch  24:49

So, yeah the cumulative price cap kicked in. And, and what what that did was forced amo to, to cap the spot price to $300 a megawatt hour. So, so we ended up going from a market operating as it normally would to a strict $300 cap. So which which sounds okay, however, the price of gas was $40 a megawatt hour, I beg your pardon, the price of gas was $40 a giga joule. Yeah, now, the short run marginal cost of a gas turbine is approximately 10 times its gas price. Okay, so, so essentially a megawatt hour of for gas turbine to produce a megawatt hour of electricity, it will it will consume, it will consume 10 Giga joules of gas. So, so 40 times 10 is obviously $400. So, if you’re a rational operator of gas turbines, you’re not going to be dispatching at a cost of $400 to to only receive $300 in revenue. So, so the gas turbine operators, rationally withdrew capacity, which was, which was not in itself sounds like a selfish thing to do, they needed to do that to allow a new AEMO to issue a lack of reserve notice, which then allowed AEMO to force the gas turbines back online. So, without that lack of reserve notice, they wouldn’t have been able to, to order the gas turbines back online, which is, which is what they do.

Gene Tunny  26:18

So they essentially they intervened in the market, they said you, you’ve got to supply this, we will direct you to supply this into the market. Correct. So the market and this is why people at the time were saying the market is essentially failed. And I mean, is that a fair thing to say that, look, the national electricity market, as it was originally designed, is no longer fit for purpose. I mean, if if you’ve got a situation where the the operator has to intervene and essentially take over and go into command and control, central planning style, is that, does that mean that whole system has failed? And we need to start it again?

Andrew Murdoch  26:55

Look I think I think, I think it’s a bit harsh to say that the market has failed, the market has operated extremely well for for over 20 years. And, and has has done an excellent job of balancing supply demand and, and facilitating private investment into the, into the market. And, and I guess modernising beyond state controlled power systems. It’s not perfect, though. And we have this situation, this extreme situation of four unusual events that happened that that was not foreseen. What was the scene was that these types of events will happen. And therefore we give, we have the cumulative price cap to act there is a safety valve to to allow a AEMO to intervene and suspend the market when when it’s appropriate. So yeah, so after a week, of, of regulated $300 A megawatt hour cap, then at most suspended the market and then set the price based upon previous bidding behaviour. But yeah, and that was essentially, essentially just to give time for people to go and have a few deep breaths and, and, and Reset, reset themselves and reset, how they were going to bid. In same way that, you know, in the share market, for example, a company might say, Okay, we need to have a market, we need to suspend trading of our shares, because we’re dealing with this issue, or we’re dealing with that issue. And every system has crisises, from time to time, and it is appropriate to suspend markets from time to time.

Gene Tunny  28:36

Yeah, I think that’s a that’s a fair point. Now, it looks like there was a close run thing, we didn’t end up having blackouts, which was good. I think they had some big industrial users reduce their demand quite substantially, didn’t they? But yeah, we did avoid blackouts of residential areas. I mean, I was concerned and I thought, what a terrible night because it was very cold at the time. Like, what if you couldn’t run your heater? That would be awful. So do you think could this happen again? I mean, how concerned should we be about this? Or do you think that the people running in the people in AEMO the people in the other agencies are overseen energy policy? Do they have this under control? How concerned should we be Andrew?

Andrew Murdoch  29:23

Well, I think look, I think it’s important to note that we didn’t have load shedding Yeah, and and you know, aside from some, some negotiated reduction of industrial load, AEMO were able to keep the lights on and the market participants were able to keep the lights on so. So that in itself is is a tribute to the to the people involved that hey, we we can as a as an industry collaboratively, do our job during, during these extreme extreme periods. Now, I guess, could the factors happen again, could the, could we find ourselves into in a situation where AEMO has to has to suspend them again? Well, the answer is yes. Because if you look at the four, the four factors, could we have very high gas prices? Again? Well, well, yes, they haven’t gone down, prices are still still expensive and Nord streams would drop to drop two to two, no deliveries into Europe. And the headlines coming out of Europe are more and more exciting. From day to day, and particularly as we move into the European into the European winter and into our, our summer, which is our our peak peak demand, very concerning. I feel that we’re globally under invested in gas exploration. We have very long lead times for project development from exploration all the way through to production is many, many years. There’s a reluctance by governments, policymakers, insurances, insurers and banks to support hydrocarbon projects. And so yes, I think gas, high gas prices will happen again.

Gene Tunny  30:55

Where would that be that exploration? Is Australia, one of the prime places you’d be exploring for for gas?

Andrew Murdoch  31:02

Oh, absolutely. Yeah. So so as I think, you know, we’ve seen We’ve seen Moratorium on on gas exploration in Victoria and New South Wales, which is reduced supply into, into into the Australian East Coast grid. There’s certainly a lot more gas in Queensland that that can be developed over, over time. So, so yeah, there’s there’s there’s, there’s a lot there that we have, we can we can contribute there. Yeah. Likewise, with coal. I don’t see. I don’t see global coal prices restoring to levels that we’ve seen in the past. I don’t think they’re going to take $400 a tonne forever. But like gas, you know, there’s reluctance in an even greater reluctance to develop and approve coal projects. Notwithstanding that, globally, we’ve consumed as much coal in the last 12 months as we’ve ever consumed. And that’s a reflection of increasing energy demand from developing economies, who are building coal fired power stations.

Gene Tunny  32:09

Okay, we’ll take a short break here for a word from our sponsor.

Gene Tunny  32:43

Now back to the show. Right, so what about this concern about renewables? Is there a big challenge integrating them into the grid? Does that make the grid more unreliable? If we don’t have the backup the storage capacity, and it looks like we don’t at the moment, we’ve got coal fired power stations, they’re going to be progressively shutting down over the next couple of decades? How confident are you arecan manage that transition? And if you know, what are the what are the things we need to do to make sure it goes well, and we don’t end up with with loadshedding with blackouts from time to time.

Andrew Murdoch  33:32

Yeah, so renewables are complex. And the obvious thing to say on renewables is that, you know, solar doesn’t work when the sun’s not shining, and wind doesn’t work when the winds not blowing the challenge for us. I guess the the key challenges is number one, accessing the resource number two, matching supply and demand, making sure that we’ve got the transmission infrastructure in place to connect the generation to the to the to the load centre, noting that the generation is going to come from your is coming from different places to where it has come from in the past. And then, you know, dealing with storage, so I guess, to, to develop a system where we have the equivalent of baseload power from renewables, you first got to generate the power. Yeah, then you’ve got to store it, then you’ve got to dispatch it. So you’ve got three elements, where we where we would once have had one so so it is it is quite, quite complex. I guess in terms of accessing the resource and there’s a there’s a lot of really good work being done. If you look at the the growth statistics in solar and wind over the last five years has been fantastic. In terms of the, the the number of megawatts that has been added to the grid. It’s still it’s still not easy to develop these projects. You’ve got landholder interest to deal with. You’ve got the interests of traditional owners, you’ve got community interests and expectations. Some people love wind farms, some people don’t. And we each have a different, different view on that. And competing, competing land use is is another another issue. So moving moving through that, I guess, you know, land land acquisition and development approval environmental approvals is complicated for, for renewables projects are land intensive projects. And so and so therefore, therefore complicated from a renewals perspective in matching supply and demand. We have very limited opportunities for baseload renewable says obviously, hydro, but between snowy and Tassie hydro, pretty much tapped all of the hydro resources that we have in the country, there’s a little bit of biomass, particularly integrated with sugar mills, I think we can make better value out of waste to energy projects. So that is using the energy in waste to generate, to generate power. And we’re going to need to to develop massive, massive amounts of storage to cover an average 24 hour load cycle. So yeah, so pumped hydro, large battery projects, and we’re working on on on a very large pumped hydro project, and two very large battery projects that will contribute to, to contribute to solving some of these problems. Yeah.

Gene Tunny  36:18

Do you have any thoughts on what this bet the future with batteries will look like? Well, well, we all have to have something like the Tesla Powerwall. At home, will there be larger batteries? on street corners? I mean, houses going to? How’s it going to play out? What are your thoughts on where the technology is out at the moment? where it’s going? Yeah, are we actually going to have the, the the improvements, the technological improvements that we need? I mean, I remember reading might have been in Bill Gates his book on on the climate change challenge. And I think you were saying we need some, you know, multiple improvement in the efficiency of batteries. I don’t know if it was 20x was some big number in that we need to improve batteries by

Andrew Murdoch  37:03

Yes, I think I think we’re going to see a mix of projects. And we’re working on some very large projects, gigawatt scale battery projects. And, and these batteries are a two hour duration. So they’ll they’re really they’re these projects are really designed to harvest solar energy generated during the middle of the day, store it and then put it back onto the grid in the evening. And essentially dealing with that dealing with that peak load, I think you’ll see, you’ll see a lot of batteries at at a at an industry level as well, we’ll see projects on the fringe of grid utilise batteries a little bit more. So for example, a mine that is in an Outback community that might be supplied by a long skinny transmission line that doesn’t quite have the capacity to serve the mind. So the mind will put a battery in trickle charge the battery during the day and then use that battery to use that battery to cover the peak demands that the mine might have, they might also integrate their own solar in there as well to to self generate a little bit so so so we are seeing a lot of batteries within industry there for for energy management also helps with things like peak demand tariffs and other related energy costs. We’ll also see batteries at a household level participators as virtual power plants, so essentially what happens there is that you’ll you’ll go and have a battery that that you’ll instal in your house and your retail supply agreement will allow your retailer to control your battery and that will allow your retailer to use your battery capacity to trade a little bit of energy. They’ll they’ll harvest the harvest the solar from your roof and then dispatch, dispatch it to your house and then whatever’s whatever the Enders and overs are they can then trade onto the grid. So I think I think we’ll see them at all all levels are at wholesale level that at large industrial level and also at at the household level.

Gene Tunny  38:59

Right. Can we talk about that gigawatt battery? That sounds fascinating. And it gigawatts obviously, a huge amount of energy. So what would that actually power? Do you know? I mean, that I mean, I guess you you could estimate it based on household electricity use, but are we took like what sort of sized town are we talking about?

Andrew Murdoch  39:22

So to put it into context, the the Peak Peak Demand in in Queensland is somewhere between eight and 10,000 gigawatt hours. So let me start that again. So to put it into context, the peak demand in Queensland is somewhere between eight and 10 gigawatts during during high high demand. So essentially, it could contribute roughly 10% of the peak demand to the state.

Gene Tunny  39:51

Right. So that’s now this is going to be in precise because industrial use is a big part of demand but 10% of Queensland. So we’ve got about 5 million people. So that’s about that’s 500,000. People. So we’re talking. Yeah, I mean, that’s a that’s a city. Right. That’s a reasonable sized city. I mean, yeah. I mean, we don’t have any main gold coasts, for example. 500,000 people. Right. So that’s a big battery, then. That’s impressive. Yeah, it is a big battery. Yes. Okay. And so that’s the sort of thing we’d be, we’d be looking at, we’re looking at large batteries to back up the grid. And so without naming names, it looks like the people who are sort of involved in this, the the companies involved in this are looking at options like this.

Andrew Murdoch  40:43

Yeah, absolutely. Yeah. I mean, investors look for opportunities to solve a problem. And yeah, that’s, that’s, that’s how capitalism works, of course, is that you, you know, you add value to the community, by by solving a problem, and then you get paid for it. So yeah, we have some some very smart clients who, who, who can identify these types of opportunities, and then deploy their capital to solve

Gene Tunny  41:06

them. Okay, because they know they can store the energy in the battery and then sell it into the grid when it’s needed. Correct. Okay. Uh, one thing I forgot to ask was about, if you’ve still got time, I know a token. Yeah, that’s right. Do we need something like a capacity mechanism in the national electricity market to to keep this coal fired power and gas fired power online? Because one of the complaints I hear is that with the way the markets been set up, and these, these certificates that mean that renewables can get beat in at negative prices, This undermines the viability of the coal fired and the gas fired generation, but we actually need them from time to time to be able to provide that was it peaking to do the peaking to provide that, that that energy when we really need it?

Andrew Murdoch  42:02

Yeah, well, I guess, yeah, we don’t specifically need coal or specifically need gas. To provide that firming capacity. We need dispatchable power. And traditionally, we’ve gotten that from from coal sources, and yeah, from gas sources. So so it’s not so much that we we need, we need coal, or we need batteries, are we need gas, or we need pumped hydro, we need something. Yeah, that will provide that, that, that, that peaking capacity, then if you overlay a climate change lens on it progressively over time, we need the carbon intensity of that capacity to reduce. Yeah. So back to your question about, do we need a capacity mechanism? It’s hard to see a market restructure being able to address the combination of geopolitical meteorological and physical issues that were were present in early, early June, those four factors still would have been the irrespective of what the what the the, the, the, what the market structure was, I think there are some tweaks we can make to the, to the system, for example, that market cap of $15,000 a megawatt hour, perhaps that should integrate down once it’s hit the cap a few times as you integrated down over time. So the cumulative price cap is not, is never, is never is never exceeded. And I think if you took a control systems engineering view to to how that price cap operates, you could put a feedback system in there that has integrated control down to a to an equivalent of that, of that price cap, which is averages out at about $800 a megawatt hour. So which is good money, if you’re if you’re

Gene Tunny  43:49

I think I understand what you’re saying. So you’re, you’re saying that maybe don’t let it get up as far as 15,000 or maybe once but then start scaling that, like just start reducing that so that they’re still getting the high prices when the market really needs energy, but they don’t get such high enough prices, that it ends up exceeding their cumulative cap, which means that I am asked to intervene and yeah, okay, great. Yeah. Okay.

Andrew Murdoch  44:18

Now, we also have another, a few other, let’s call them quasi capacity mechanisms that are in the system already. And that, as I said that that $1,500.15 $1,000 A megawatt hour is a significant incentive to make sure that you’re well invested in in pacity. And those that weren’t lost a lot of money. So the the other the other thing we have is we do have the contract market on the side. So if you’re an energy retailer, you can go and contract with with the power station to to provide you to provide you with with coverage and essentially they’re providing a physical slot. So every time that the pool price goes up, they will generate on your behalf and you’ll swap that exposure. So so that’s, you know, that’s a A non let’s call it a voluntary capacity market that already exists. And email also has the reliability and emergency reserve trader. And that’s a short term mechanism that whenever a emo feels that the based upon it’s more than just feeling it’s based on some some very sophisticated modelling that the the probability of unserved power exceeds point oh 2%, then they’re able to go and contract with generators to, to provide emergency power during a particular period. And that led to some some temporary generators being being installed in various different locations around the country over the over the past few years.

Gene Tunny  45:42

Temporary generators are they diesel generators? Oh, they

Andrew Murdoch  45:46

could be diesel could be gas. So yeah, so you can you can go to GE and order some trailer mounted 30 megawatt trailer mounted gas turbines. And there’s there’s fleets of these owned by hire companies that that go around the world? And, and, and plug holes in power systems here and there. So

Gene Tunny  46:05

very good. Okay. Yeah. So we were chatting about the capacity mechanism. And I think you’re saying that it’s not going to solve all the problems that that could that could arise, which would, which would cause which would cause issues? So I mean, what, what do we need to do? Do you have any thoughts on what needs to happen with the NEM.

Andrew Murdoch  46:28

So I guess, reflecting on the events of June, more energy would have been handy. So it was a cost of energy issue that that created these extreme prices. So whether that energy came from renewables or from gas or from coal, any additional gigajoules or megawatt hours generated onto the system would have had downward pressure on prices, and certainly would have helped. So there’s a couple of tweaks you can do to the you can do to the to the to the rules to perhaps prevent the accumulated price stress on ever been ever been breached? And that’s just, that’s just a function of mathematics.

Gene Tunny  47:07

That was what we were talking about before. Yeah, yeah, yeah,

Andrew Murdoch  47:10

looking forwards. We’ve got 8.3 gigawatts of coal plant sheduled to be taken out of the market between now and 2029. It’s like 2022. Now. So that’s a lot of a lot of firming capacity needs to be developed in that timeframe. If I look at the various different committed projects that are that are in the system, at present, I only get that only adds to 1.32 gigawatts of dispatchable generation required to cover that 8.3 gigawatts of retiring capacity. So so there is a bit of a deficit there in terms of project firming projects that are available. Now more projects will be be committed between now and then. And those projects I mentioned before, aren’t included in that 1.3 gigawatts. But yeah, these these projects we’re working on are in the development phase development phase for projects is, is very long takes many years. There’s a there’s a lot of hoops to jump through. Some of them necessary, some of them not so necessary. So it’s a bit like the argument in house prices and housing demand is, you know, is extreme high house pricing being caused by the the complexity and speed of approvals, or are there other factors that played personally my my view in power is that we could, we could certainly work a lot faster in terms of bringing these projects onto the onto the grid. If the approvals process wasn’t so bureaucratic and slow. Now, I think it should still be thorough. We certainly, we certainly want to have a thorough EIS process and a thorough technical review of of the contribution that these plants have on the grid. But I think there’s a lot we can do to make it a lot more efficient and perhaps remove duplication. And yeah, and and yeah, I guess add a little bit of I want to say common sense, but that’s not quite the right word for it, but

Gene Tunny  49:23

we do maybe a sense of urgency among some of these regulatory agencies. So you mentioned the EIS environmental impact statement. And I guess, yeah, trying to respond to the environmental issues that that’s obviously a major part of the whole process. Trying to satisfy the environmental regulator that you’re not going to damage the environment. You’ve got a plan, like if there’s a particular there’s foreigner that’s threatened, you’ve got a plan to manage that. So yeah, yes,

Andrew Murdoch  49:53

essentially. Yeah. And I guess, you know, to be fair to this is not just one one agency that the could improve. We see it across all all, all agencies. The the, I guess is there’s a desire for perfection, that that whether whether it’s whether it’s a technical approval or or a planning approval or a or traffic or whatnot, every, each of the departments come wanting to see a level of perfection in every every area, and sometimes it’s just not practical.

Gene Tunny  50:29

Yeah. Okay, I’ll, I’ll put something to you. And I’d be interested in your reaction. I’m looking at what’s happening with energy in Australia at the moment. And I see, we need all of this firming capacity, or we need to be able to back up the grid because we’re bringing in all these renewables. We’re coal fired power, leaving the system. And I mean, I look at this, and I’m very worried about whether we’re actually going to have sufficient power in five or 10 years time, I’m really worried about the reliability of the system. And partly, that’s because I’m concerned that we’ve promoted renewables into the system at a very high rate, but faster than the system can can handle it and not in conjunction with the storage. And we’ve done that for Well, we, I mean, I think, you know, the people are doing it for reasons that, you know, I think they, they think they’re doing the right thing, because it’s for the environment, it’s to tackle climate change. But I’m worried about what that means reliability of power in five or 10 years. And what that will mean for prices, How worried should I be? Am I just am I overly concerned? Am I too concerned? Or is that there might be an irrational, am I being biassed myself in analysing this issue? yet? So

Andrew Murdoch  51:51

I think we can’t oversimplify, or we shouldn’t be oversimplifying the debate. We are talking about complex physics and complex economics. And whether it’s in the media or in politics, there’s these oversimplifications of the answer is x. And depending upon what your political view or your commercial view is your put whatever noun you’re after the answer is to to suit your needs. I try and take a balanced view. Now, in terms of, Should we be worried at a technical level? So I’ll get back to those numbers. Again, there’s 8.3 gigawatts being retired from the fleet between now and 2029. So we’ve been through an incident where, essentially, yeah, it was more of an energy related issue than a capacity related issue, but capacity wasn’t far behind. So we, we have kind of almost just enough right now. Okay. So when we retire 8.3 gigawatts, and we increase peak demand, because peak demand continues to grow, you’re on. And we want to we want to continue to to industrialise and we want to continue to grow the population and grow the economy. And there’s a strong correlation between energy consumption and GDP. So that, you know that that margin is probably going to go negative. And so we should, yeah, we should certainly be prioritising firming capacity. And as I said, previously, whether that firming capacity comes from batteries from gas turbines, from pumped hydro is somewhat somewhat irrelevant. There’s probably still a role for coal to play, but it gets a little bit harder for for, for coal plant to, to provide, provide firming, in terms of, you know, should we be worried about capacity in the future? That’s, the answer is yes. And or just scroll down here to have a look, I was reading over the weekend, the HMOs. Electrical statement of opportunities, which essentially is a forecast of off demand that they use to inform the market. So they’re forecasting that the reliability standard will be breached. If there’s no further investment, that the reliability standards will be breached in New South Wales in 2025, and then Victoria in 2027, and Queensland and South Australia shortly thereafter. How web are if the FA Mo’s recommendations in the integrated system plan, which is a Mo’s map of the projects that they feel should be progressed, then that situation improves a little bit we don’t see the reliability standard being breached in in Victoria until 2027 28. And then, New South wails 2029 2030 But again linked to coal plant retirements,

Gene Tunny  55:05

I have to look at this integrated system plan, what are they? What are they saying in that are they saying, you know, these are these are the investments that are needed in what capacity and in storage and distribution. So,

Andrew Murdoch  55:17

so it deals, the integrated system plan deals with the transmission network more so, than the generation network, they do look at where they believe the, the more, the better renewable energy zones are on the grid and, and that informs a lot of the infrastructure. So that allows them to forecast where the energy is going to be coming from in future years. So it’s essentially feed into the regulated process. So once I emo identify a project that then allows the network service providers, so the power links the trans grids, to start the regulatory investment process, which then allows them to invest in these in these upgrades. But yeah, the timeframe between amo raising a project in the in the ISP and then a network service provider to actually construct and commission a plant is many 510 years in the making. So So these these are big infrastructure projects that take a long time to develop and construct

Gene Tunny  56:21

good one, I’ll check that out. I’ll check out this ISP and put a link in the show notes. One thing that one thing that’s occurred to me is that I mean, one, one possible way to avoid this, this deficit that you’ve you’ve described is, well, we just don’t retire these coal fired power stations, we keep some of them open or longer than is intended or was initial longer than amo thinks that other companies themselves think they will be currently be kept open for. But what that might mean is that’s where that capacity mechanism could could be useful, possibly, but then that means that we’d be paying then just to have the generation available if it’s needed. And that’s why there are accusations that our capacity mechanism would be coal keeper. Have you heard that? Yeah. So

Andrew Murdoch  57:06

I’ve certainly heard the call keeper fever slogan. Yeah, look, it’s it’s interesting. I’d have to think about that a little bit more as to what would a capacity credit encourage a coal plant to stay open more so than the current market structure? I guess the economics of ongoing operation of coal plants on one hand, you’ve got back to a world where energy prices are, quote, unquote, normal. On one hand, you’ve got a very low cost of operation, then you’ve got four, seven production. So you’re you’re it’s true baseload and the volumes are higher. On the other hand, you’ve got ongoing refurbishment costs. So I think callide spent $130 million or so on the refurbishment of one of the B units recently. Yeah, that’s a lot of money. And so you know that that’s an that will keep that that plant operating for another five years for argument’s sake. So it’s always it’s always that economics of, you know, when you’re between major overhaul cycles, and you keep going until the until you hit the next major maintenance. And then and then you make a decision. Do I spend $100 million? Upgrading? Yeah. refurbishing, economy or economy economizer tubes or whatnot? Or do you or do you at that stage retire the plant?

Gene Tunny  58:29

Okay. Okay. Look, I better I only ask one more question, because I’m so long, because this is fascinating. And I really liked the point you made about how, look, let’s not look at this, simplistically, it’s too easy just to come up with some simple diagnosis of what’s going on. And as economists we like to do that, because we like to cut through the complexity. We like to have a simple, elegant model of what’s going on. But I understand Yep, you’ve got to think about the physics and all of this as well as the economics that makes perfect sense. My final question is about EVs. Are we ready for EVs in the network? Will we be able to provide the power? Will we be able to provide the necessary charging infrastructure? And one thing I should I’m interested if you’ve got any thoughts on it is how can EVs help us have a smarter grid? Because I’ve seen that in I think it’s in California? Is there a company that lets people who have EVs they can have that use them as a bit of a mini as battery? And then they can they can even start selling power to other people? I don’t know if you’ve seen that sort of thing. So if you could just talk about EVs?

Andrew Murdoch  59:38

Sure, certainly certainly. Great. I just want to go back to the Nikah the the complex physics and complex economics. I just want to make one other point. There’s also an ecological impact as well as your Yeah, is it every choice we make, it has an impact on cost. It has an impact on reliability, but it also has an impact on carbon emissions. So truth is balancing the three and three issues are all common. looks. So back to EVs. Yeah. So, so So yeah, fascinating stuff. And, and obviously, you’ve had a couple of guests over the last couple of weeks who have had some some interesting things to say on EVs. But yes, so there are there are companies who are planning on using the battery capacity in your Eevee, as part of that virtual power plant mechanism that I was talking about, yeah, with a battery on the wall, that you can also extend that by plugging in your Eevee and allowing them to use that charge. So maybe you’ll come home from from from work, you’ll drive into your garage and about this time of evening, that’s, it’s 6pm, here and in. So you might come home and plug in in the evening, and you might still have 80% of your battery charges there. So the the your retailer might use that to cover peak demand during the evening, rather than drawing from the grid. And then later in the night, when peak demand goes off, and power prices get a little bit cheaper, maybe the wind starts blowing a little bit, then your your retailer will then fully charge your car. So the next morning, you get up and unplug and away you go to work, and you don’t even know that it’s happened. So So yeah, so these kinds of things can be can be done, I noticed, I was reading on LinkedIn, I think this morning, the the Tesla’s in in California, over the last couple of days have been setting you people will go home and the Tesla comes up on the on the Tesla display. You know, the California grid is about to experience peak demand, you might like to charge your car later in the later in the evening. And the Tesla system has an ability for you to time to essentially tell it when you want to leave and it will optimise the charging process a to maximise battery life and also to minimise power costs and impact on the grid. But I guess in terms of physical impacts, look, if we all go home in the evening and plug in our EVs in the evening, then that’s going to contribute to peak demand. And that’s not going to be particularly helpful when it comes to reliability of supply. Yeah. But if we time the charging of the car to be a little bit later in the evening to in the morning, three in the morning, and as I say the Tesla’s can do it. And I’m sure the other EVs can do it as well, with smart charging, then, then the impact on the grid will be will be minimal, because we’re making better use of matching, we’re using the cars to to maximise supply and demand.

Gene Tunny  1:02:31

Right, based on so how does it work? So the you mentioned Tesla, so they’re looking at what the the power prices are, they’re getting a signal from the market. And they’re saying, Oh, look, you might you might want to charge later. Because there’s a lot of demand for power at the moment. And prices are high.

Andrew Murdoch  1:02:53

Yeah, so in the case of the California one it was it was more around reliability. So okay, as I understand it, California is going through a situation that was similar to what we went through June, where they’re, they’re issuing lack of reserve notices, or whatever the California for the lack of reserve notices. And so it’s more so more related around around system system reliability, rather than rather than price. Okay, but there’s no reason why it couldn’t also respond to price if it’s integrated with the with your retailers.

Gene Tunny  1:03:23

Okay. That’s, that’s cool. And just finally, so yeah, so I guess you answered the question. You’re saying that, if we do it intelligently, if there’s some if there’s some way with a possibly buy it, that, I guess it would be via it that these things are charging at the right time? During the night? They’re not all charging when we get home? That they’re delayed, then yeah, it’s possible we we should be able to handle it in your view.

Andrew Murdoch  1:03:54

Yeah, yeah. Yeah. So that’s not to say that won’t have any impact that will have an impact, because there’s more energy that the power grid needs to provide. So if it is all coming from from renewables, and that’s more solar farms and more wind farms, because we still have to produce more megawatt hours of energy and transmit them. Yeah, so it all contributes to load growth. And there will be there will be EVs that do have to be charged during the peak because I’ve just come home or maybe I’ve driven home from a couple 100 kilometres away. Yeah, 2% left in my battery. And in an hour’s time, I’ve got to pick the kids up from school. So I’ve got a charge now. So there will be a contribute contribution, but it won’t be won’t be everyone most of the time for most of your daily cycling will be able to charge during during periods. When when it’s not peak demand. And do

Gene Tunny  1:04:39

You think this will be done automatically? Will there be the computer the in on the in the car or and it connects to the grid and then this will all be managed and coordinated across all of the EVS out there and yeah,

Andrew Murdoch  1:04:51

Yeah, so So Rena did a study. And they found that when people were just left to their own devices, people would come home and plug in Yeah, 30% of all charging happens during peak periods. Yes. Because that’s when you come home. If they, if they then get gave a 10 cent per kilowatt hour incentive, this dropped 10%. So people started thinking about it, I want to save some money or save some money on my power bill. So I’m not going to I’m going to programme car did not start charging into after peak period. And then if they handed over control of the charging to the retailer, then that peak demand use dropped to 6%. Yeah, so Gotcha. So automation is definitely the way and who wants to come home and think about oh, what time should I charge the car? Yeah, I can just plug it in and have have the AI work it out for me. And as long as I don’t know, if I don’t have to think about it, it’s easy.

Gene Tunny  1:05:44

Yeah. Extraordinary. Okay. We’ve, I think we’ve probably come to time because yeah, we’ve had a great chat, Andrew. And, yeah, I’ve really enjoyed this conversation and learned an incredible amount. So it’s been incredibly valuable for me. Any final words before we wrap up? Oh, no. Look,

Andrew Murdoch  1:06:04

thank you for the opportunity to talk. As I say it’s a complex system. We’re balanced. We’re balancing our contribution to climate change. We’re balancing economic development. We’re balancing physics, we’re balancing reliability, and we’re balancing affordability. So it is it is, it can’t be over simplified.

Gene Tunny  1:06:20

So I think that’s a really good way to to put it. Andrew Murdock, Managing Director of RK energy. Thanks so much for your time. I really enjoyed that conversation. Thanks,

Andrew Murdoch  1:06:29

Joan. I appreciate the opportunity.
