And now, your hosts.  Allen Hall 2025: Welcome to the Uptime Wind Energy Podcast. I'm your host, Allen Hall, and I'm here with Rosemary Barnes, who's been busy in Australia up in Sydney at a energy conference. Rosemary, what happened this past week?  Rosemary Barnes: Oh, yeah. I've been up in Sydney for the Smart Energy Conference and Exhibition. It's a big... I don't know if it's the biggest. I think they get about 12,000 people or something through the doors. So yeah, it's, it's one of the big, maybe the biggest, um, energy conference in Australia. It's really focused on distributed energy households. So in the past, it was, like, nearly all solar, um, like rooftop solar. There used to be lots of installers that were there and, yeah, there's heaps of solar [00:01:00] panels around in the exhibition hall. And over the last few years it's been a mix of batteries and solar, and then now this year it was basically 99% batteries, 1% EV chargers, and almost not a solar panel to be seen. I didn't actually spend that much time in the exhibition this year. I mostly was, um, attending sessions. Andrew Forrest from Fortescue headlined, and that was really good. I haven't seen him speak live before. Y- you know, he, he told about all the, like, good plans that Fortescue's doing to get to real zero by 2030. So he's on a real rampage at the moment to try and get rid of the diesel rebate that we pay at the moment. We pay diesel users a, a, yeah, a fuel, fuel rebate. It was just cool to hear about y- you know, all of Fortescue's plans, why they've got this big green grid that they're building out in the Pilbara. Um, I really liked when he said, you know, it's not, it's not magic, it's, um, it's just, what did he say? Like, maths, physics, engineering, and [00:02:00]economics, and a bit of courageous leadership. That's what you need to make a green, a green electricity grid. So I really like that the, you know, engineering was mentioned, was mentioned there. I did actually get the chance to ask him a question, too. Wanted to know, um, you know, like, Fortescue is, is really one of the most interesting things about the company is that they are using brand-new technologies or even not quite there yet technologies. I asked, uh, Andrew Forrest, I asked him, you know, like, how you make these bold, bold decisions, does it ever, you know, worry you that it's not gonna work out? And I was assuming he would say, "It doesn't worry me," um, because, you know, he has that kind of brash, confident personality. So I, you know, my follow-up was, what, what steps do you take so that you aren't worried by it? And he said it does worry him, and he s- stays awake every night worrying, worrying about if these technologies aren't going to work. And that, uh, basically they try and have a really, really solid plan B that isn't a [00:03:00] brand-new technology. So, um, you can, you know, infer from that, that if the-- I mean, first of all, he said, "We don't invest in the technology until they have demons- demonstrated with a good prototype that it's likely to work." Um, but I guess that, you know, assuming that they've ran into problems in the rollout of all of these Naberebo towers, that, um, they have a backup of some conventional towers.  Speaker 2: Yeah, uh, the, the Fortescue people, when we talked to them about, pfoof, probably six months ago, maybe a little bit longer, we were helping to build a farm out in Western Australia. It was a small team, much smaller than anything you would see in the US, and it does sort of align with the Australian approach to it, is that you don't need a massive team of people to do these projects. You just need to know what you're doing, and that was really remarkable. So e- I'm not surprised that Fortescue is continuing on in, in different aspects. It does seem like they're pretty bold about their engineering approach and taking on massive projects that otherwise wouldn't be [00:04:00] done and-  Rosemary Barnes: It, it's also really cool to hear, uh, Andrew Forrest or anyone from Fortescue talk because they're talking about things that they've done. You know, like we have so much when you're at these, uh, events and, you know, everyone's doing these inspiring talks, it's always about, "Oh, this is the possibility for the future." But Fortescue has actually, has actually done it. Yeah, there was a lot of, like, actual progress discussed at this conference. It wasn't, "This is what we could do if we all joined hands and sang Kumbaya." It wasn't like that, you know? It's like, this is what's happening when the engineering is there, the economics are there, and the government isn't standing in the way. Um, y- you know, you can make a lot of, a lot of progress. And you know what? Like now we've got so much distributed energy in Australia. It's the rooftop solar that we've been building for, you know, 20 years by now. Um, and it's the, the batteries especially. Like it is a- starting to have a noticeable impact on electricity prices, and co- coal and gas are both reducing in the grid. I think the last quarter of gas use in Australia was the lowest it's [00:05:00] been since 1999. Like, um, yeah, so it's, yeah, it's, it, it's dropping, you know? And so I think that that's a really unique story for Australia is that households can actually really change the dial.  Speaker 2: Well, can I ask you about that? Because the data center issue is popping up again in the United States, and one of the things about data centers is they feel like you, you're gonna need a good amount of batteries to support if the grid hops on or turns off, that they wanna be able to support this data center, so having a buffer and batteries would make a lot of sense. However, there's not a lot of battery storage in the US at the minute versus a place like Australia where there's a lot of it. Doesn't it make a lot of sense to start putting data centers in Australia? I still don't understand Why that hasn't been done? Because electricity prices are cheaper, the land is available, the infrastructure's there. It's going [00:06:00] to be, you would think, easier to build in Australia than it would be in the United States. What's the dilemma there?  Rosemary Barnes: I think certainly there are plenty of plans to build big data centers in Australia. Um, and now I'm gonna go, like, move a little bit outside my expertise, but I think that one of the issues is that at the moment, a lot of the data centers need to be quite close to where the work is happening. So I mean, you're always gonna need data centers close to any big city where people are, are using the internet. Um, but aside from that, you know, like, the tech sector in the US is much bigger, so the people actually developing, um, you know, training, um, uh, yeah, training AI models, um, are more likely to be sitting in the US and, you know, need a large amount... Not all of their compute needs to happen nearby, but a fair chunk of it. And so I think that that is one reason why so far that's where it is. Um, but it also doesn't mean... I mean, there's [00:07:00] plenty of smart, um smart computer types in Australia as well as the US, so you could start to see more companies moving, um, moving to where electricity is cheap. I think that-- And grid connections are fast.  Speaker 2: The one thing you notice about using any of the AI platforms today is, like, there's a built-in delay. Unlike when you're on Amazon or any other s- active site, when you click, you want something to happen immediately. With AI, they, they build in a little wait process, which means you can have a data center anywhere, because you're not expecting an instantaneous response from it. That means, in a sense, they're setting it up to be a global industry. There is more of a delay now than there was a month ago. And I assume that has to do with usage, and they're trying to manage all the data usage, right? So electricity is one of the limitations in the United States. That's evident right now. The amount of data centers is a problem, so they're trying to spread out the usage, and they are definitely... At least Anthropic is slowing it down. [00:08:00] I'd imagine all the other ones are doing the same thing. So it does open up the world to cheaper electricity.  Rosemary Barnes: There's heaps of really interesting work happening in trying to get, um, AI and data centers to be better grid citizens, not probably primarily out of the goodness of their heart, but because of two things. One, grid connections are really slow, and so there's a strong incentive that you can save, in some places, years off your development time if you can just bring in enough batteries, enough smart tech to make sure that you're never going to, um, you know, add to peak, peak load in the grid, then you can- You know, change how things go. It's also a matter of, like, social license as well, because at the moment it's probably not too bad. People don't realize too much. But if people's electricity prices start going up because, you know, grid had to be built out because of da- data centers,...
