    Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall here with Nikki Briggs, who is in North Carolina this week, and Yolanda Padron who is back from the exciting wedding and weekend in Mexico. Welcome back, Yolanda. 

    Yolanda Padron: Thank you. Excited to be here, 

    Allen Hall: uh, this week there’s a, there’s a lot going on and we’re gonna touch upon some of it.

    Uh, Rosemary is over in China this week and Matthew is actually at Wind Europe in Madrid. And so this is gonna be an American focused episode mostly, but it’s gonna have global implications. One of the key items is PPA prices in the United States and with the on sunsetting of the [00:01:00] IRA Bills, uh, tax credits, and the whole infrastructure there with the one big beautiful bill when it crushed the IRA bill.

    PPA Prices needed to come up well. That’s happening, right? So developers, uh, can’t live without some money to compensate for the roughly 26, 26 7 20 $7 in PPA prices that were compensated by the tax credits. But, uh, when purchase price agreements have hit the highest level since they begin tracking it at Wood Mac.

    The average wind PPA now stands at $79 and 40 cents per megawatt hour up 24% from just one year ago now, Yolanda, you and I were talking before we started recording today about how low some of those PPA prices were two years ago, three years ago. Some of them were almost single digits. 

    Yolanda Padron: Yeah, yeah. Some of them were pretty low.

    I [00:02:00] remember 16, $19 EPA prices and then a couple years ago we were looking at those and thinking, oh no, I can’t believe we, we kept those prices and they’re so low and everything’s changed so much, and the prices grown so much, and that was two years ago and now it’s, it’s, it’s, it’s almost four times as much as, as what we had originally thought, which is.

    Not super great for those older projects, 

    Allen Hall: obviously, uh, when they, if they do repower, the extent they’re gonna have to renegotiate the PPAs. Right. The, the landscape has changed quite a bit. So the, the question really is now are they gonna be able to renegotiate new PPAs when the existing PPA hopefully ends?

    You can’t, you can’t run turbines for free and will they repower. Or will they just try to extend the lifetime? I think it’s a lot of operators trying to figure that out right now. And that’s in light of installations. So Whim Mac also says that US wind installations are [00:03:00] on track to nearly double in 2026, uh, building towards 48 gigawatts of new capacity through 2030, which all makes sense, right?

    That the, the. Uh, everybody’s trying to get all their assets in the ground so they, they qualify for the, the tax credits. So there’s a big push. So 2026 and 2027 are gonna be pretty busy years. Uh, but the, the negotiations are still going on and we’re talking to operators. Nikki and I have been talking to operators this past week or the last couple of weeks, honestly.

    There is all kinds of negotiations going on for turbines right now and who can get turbines? Can they get ’em in time? Can they get ’em planted fast enough? Nikki, it is causing a lot of operators to spend a great deal of time doing planning that they otherwise wouldn’t have been working on two years ago.

    Nikki Briggs: Definitely. I mean, it seems kind of weird to me because it’s like a weird spot. It’s like, um, you know, we want more power and we need to do all these projects, [00:04:00] but then. The permitting process is just like a brick wall or something, you know? Um, like it just takes them so much more to get through, um, and get it moving.

    Allen Hall: Well, I, I think if you have an existing site, you’re gonna repower it. I mean, that’s probably the easiest thing to do if, if you can pull it off. The, the question is how big of a turbine are you gonna purchase? A lot of those turbines that are gonna get repowered are probably 1.5. To two megawatt machines.

    They’re going to move up to five or six megawatt machines, generally speaking. So they’re reducing the amount of turbines that are gonna be on site. But the, the amount of power that’s delivered usually is about the same, maybe a little bit more. Which, which, which strives the, which drives the, the equation of, Hey, what’s everybody gonna do in the next couple of years with the data centers.

    Having listened to the GE Renova financial report for Q1 that just came out as we’re earlier today. GE is trying to sell gas turbines like there’s no tomorrow. However, the weird thing about it was that they were [00:05:00] very nervous about locking in firm orders that a lot of the deposits they had for like 2029 or moving into 2030.

    So they had a, a discussion about GE Renova building gas turbines. They could do about 20 gigawatts a year, but they had like a 10 gigawatt hole. In 20 29, 20 30 of orders because the data centers are realizing, like to get a contractor to put a hole in the ground so you can put a data center in is taking more time than they thought.

    It’s not Silicon Valley where you can just type some software. And Yolanda, you’re kind of in the middle of this right now, being in Austin, Texas. Is the, the drive for data centers and the drive for power, what it was six months ago, is that landscape changed? Has everybody come back to reality? Like building physical projects takes time.

    Yolanda Padron: I think people are starting to get, get back to reality from the little bit that, that I’ve been, that. I privy to, uh, I do think that you mentioned the GE renova and [00:06:00] just kind of all the changes and everything. And I know in the past we’ve talked about, um, the fact that, you know, a lot of blade manufacturers have changed hands for wind and a lot of things are uncertain in general.

    Um, I think right now with the boom of people trying to repower and doing everything as quickly as possible and as safely as possible, it’s really important that everybody should. Try to get as much documentation on everything as possible, not just to, to protect yourselves, right? I mean, if there’s some sort of, I mean, you’re, you’re, you’re checking that the foundation on your turbine is perfect still, um, doing all the civil engineering studies that you need to do and making sure that, that everything’s fine, um, for, for the long term, right?

    If you’re not, you’re not planning on repowering again in five years. Um. But just to track everything. There’s so much movement right now and so much uncertainty that at the very least, so you know, what you’re dealing with, if and when you have an issue, [00:07:00] you know, five years down the line, like, oh, this is what happened and this is why, this is who I need to talk to, or this is how I’m going to solve this.

    Or, you know, it’s not a new problem. Um, because it’s just, there’s just so many, so many factors changing. All at once that it’s, it’s a little bit, it’s a little bit daunting for everyone in this space. I don’t know if you guys feel the same way. 

    Nikki Briggs: I have a separate question, um, which is, you know about these PPA pricing, if it’s going up, it continues to go up.

    Is the old adage about like green energy is the, is is the cheapest? Is that like out of the wind now? I mean, that’s not even. You can’t even apply that. 

    Allen Hall: No, I think renewable energy, solar and wind are the lowest cost, fastest way to get power onto the grid. The, the, the question is, uh, will state and federal governments prohibit it?

    Because if you’re talking about the gas turbines, [00:08:00] which is not cheap, and you’re talking maybe the earliest is 20 30, 20 32. Uh, as when you be able to, to get something scale there. What else did there that you’re gonna build? Nuclear. Nuclear GE iss. Talking about nuclear small modular reactors again today.

    And they got a project going up in Canada, it sounded like that’s not vast either. So if you’re talking about speed and deployment, solar’s quick, right? You can just put ’em up and you can get wind turbines up pretty fast too. But anything that’s uh, gas turbine or god forbid, we start burning oil again to make electricity.

    Uh, I, I just don’t see it. This has implications obviously over in Europe too, right? So Wind Europe is this week, and it’s in Madrid, of course. And the Vesta, CEO, Henrik Anderson’s, uh, told the audience over in Europe that, uh, hey, there’s a lot of choices to be made [00:09:00] here the next couple of years, and it’s more important now than ever, uh, to.

    Think about renewables with the problems in the ous, straight of ous, sending prices higher. Does Europe want to be connected to a petroleum future? I think Europe has been struggling with that since obviously the Ukraine war started. So the, the problems in Iran are just gonna double down on that. The EU Energy Commissioner, uh, Dan Jorgenson, uh, called it out.

    Earlier this week and said it’s, this is not an energy crisis, it’s a fossil fuel crisis. So if we don’t have to rely on fossil fuel so much, then the energy crisis will hopefully come down in Europe. Uh, but one of the weird things about what’s happening and where Europe is, although Vestas and the EU energy Minister Commissioner are talking about fossil fuels and moving to electricity into more renewables, when [00:10:00] Europe is talking about, uh.

    Unfettered media posts that are, that there’s misinformation happening and, and how they’re going to deal with misinformation. That’s not their, to me it’s not their problem. Misinformation is not slowing down projects you, you have to deal with. Uh, obviously people are gonna oppose power plants, Tesla facilities, whatever’s going on in their neighborhood.

    The, there’s gonna be opposition to it. You have to learn how to deal with it. And I, I’m always shocked when, when a, a large organization, be it American Clean Power or, or Wind Europe or one of the many others, or complaining about misinformation, they’re in their information business. They need to be doing more work, laying the groundwork locally to deal with some of these issues.

    But it does feel like. Yolanda have seen this up close, uh, where there’s been sort of local disputes about, particularly wind, uh, that you, you need a little bit of help, right? [00:11:00] You can’t rely on the, the operator, owner operator to provide all the ammunition to, to, to fight off. Uh, you know, the, the generic Facebook posts about wind turbines killing birds or whatever they’re gonna post.

    Is, is there a, a, a future here where a a, a Wind Europe does a, an American clean power for that matter, do a better job of communicating why you would wanna have renewable energy in your backyard? 

    Yolanda Padron: I think we just all need to just agree in general about what our approach is here. Right? Because we, I know there’s, we’ve talked about companies that really, really wanna do, you know, if, if you can.

    Produce X amount of money by creating wind power, then you’re, I’m gonna charge you X minus one. Right? Like, I’m gonna maximize my profits as much as possible. Um, and then there’s other people who are just really, really trying to, [00:12:00] to do with, deal with what they can. You know, they, you have 25-year-old projects that have been going on forever and ever.

    No one’s manufacturing them anymore. And people are still finding solutions to keep those alive. And then there’s, I know we talked about, I think it was Japan that was doing that really crazy work with these smaller turbines that, I mean, they already know what the issues with those turbines are. So just, just removing a lot of the factors going into something very experimental for, you know.

    We could all talk about the greater good, which is making sure that renewable energy is something that’s financially accessible. Right. I, I know we have a friend who’s been talking about it for a really long time and he said, you know, it shouldn’t be a thing of this is the right thing to do, should be a thing.

    This is the most cost effective thing to do, and I think he’s right. I think we should all just really try [00:13:00] to make sure that we work together. To make it the most cost effective way of producing energy, um, of solving all the problems that we can and not just, I mean, we can focus about competition later, right?

    If we really, really want to. 

    Allen Hall: Let’s talk about the, the power demand for a minute. So, a number of states in the US have prohibited data centers altogether. I think the number I saw last was like 30 states have prohibited. Data centers main being the most recent one that I recall, where they just prohibited ’em in the state.

    That has to do with electricity prices. That the concern is if I have a couple of gigawatts being devoted to any, you know, uh, ai, Facebook, Google, uh, x, ai, any of those that my electricity rates are gonna go up and, and a lot of the states are putting blockades in essentially to prevent that from happening.

    That changes the landscape dramatically, right? [00:14:00] Where now, uh, if they were gonna put renewable energy in, in advance of ai, those projects are gonna die, obviously. Is there, is there a, a place where data centers, ai, electricity demand being increased, is met with renewables and some logic? Will that ever come to a place where everybody will be happy?

    Yolanda Padron: I mean, I think it can, in that case, I guess when Europe is correct in saying, you know, we need to stop the misinformation spread, right? But it’s also, I think it’s, it’s, it’s like one of those things where it’s like, it’s such a small part of the equation to make sure that the people who don’t exactly have a lot to do with the decisions that are being made.

    Legally, um, are on the same page. I think it’s more of, you know, the people who [00:15:00] are making these decisions need to come to an agreement on what’s, what’s best and what’s fiscally responsible for the area. 

    Allen Hall: Would you wanna turn away? I, I think the thing about AI data centers and the issues that’s driving it, it’s once you have a AI data center up and running, there’s hardly anybody working there, so it doesn’t create jobs.

    A lot of times they don’t even have lights. Right? Why do you need lights? The computers don’t need lights. They’re just gonna sit there and run that. If it was bringing jobs, I think everybody would think differently about data centers. But because data centers don’t bring jobs, except in the power generation side, there’s not a big incentive for states to allow them.

    So I don’t see how this works. Right. At some point, somebody somewhere is gonna figure it out. That I’m gonna have to have a lot of excess electricity. Maybe it’s Norway and it has to be pretty cold again, Norway or Sweden, where I could put data centers and it, it may not even happen in the us. Is that what we’re, is [00:16:00] that what we’re gonna see?

    Nikki Briggs: I don’t know what we’re gonna see, but I’ve, I’ve heard that, um, aren’t they putting data centers in the, in the water now too underwater and like in the ocean and there’s talk about putting data centers in space and, you know, all kinds of things to, to find these different environments. But I think, um, with the.

    Increased demand and power that it’s gonna be all these data centers are gonna be taking. And as, um, we know AI is very exponential, right? So it’s, it’s growing exponentially in the use and, um, the adoption of it and the models are getting stronger and so it’s consuming a lot more energy, right? And so I feel like the switch back around to sustainability as, as, uh, like a core need of.

    Of the Earth is gonna have to, it’s gonna have to come back around for sustainability. I mean, because you can’t, you can’t just keep doing that. 

    Allen Hall: I think the thing is, in, in Europe, they [00:17:00] obviously are interested in having some AI data centers, and that will be the, the growth plan of course, because they want to be able to compete with the rest of the world.

    So Europe will be in this mode of we need to create more electricity. But they want, at the same time, decouple from the Middle East and maybe even from the United States in terms of using, uh, petroleum based products to, to power their grid. I think that’s, that’s inevitable. So they’re gonna have to make a huge change in Europe.

    We’re, we’re looking at massive changes in the US who knows about China right now. Uh, what they’re planning to do besides pour money into everything, all the above strategy is what China seems to be doing. Does that then. If, especially, let’s just talk about the GE and over thing. So, Yolanda, I think this touches your point, which is GE and over win business is really not healthy.

    They lost about 300 plus million dollars in the first quarter, EBITDA wise, uh, compared to, uh, roughly a [00:18:00] year ago. It was like a hundred million dollars they lost. So the, the continued pain at GE Renova Wind. Uh, is maybe, which I thought was gonna flatline, it seems to be getting worse. All of a sudden. They think it’s gonna be better in the second half of the year.

    And maybe that’s true. Hopefully it is. But if you’re, if you’re talking about putting on more data centers, more electricity demand, just ’cause of population growth and your wind companies maybe besides vestus or not doing that well. Do we get there? Does, can we, can we do this? Can we actually turn this corner, make that turn, get onto, uh, more electricity, be able to compete against the world in AI and everything else, electricity wise.

    Is this gonna happen or is everybody gonna. Take a five year pause while they figure it out. 

    Yolanda Padron: I just think that everybody’s just kind of running with their shoes untied, right? Like we’re all trying to race. 

    Allen Hall: They’re running with scissors and the shoes untied. 

    Yolanda Padron: Yeah, it is like it. I mean, eventually someone’s gonna have to [00:19:00] pause or trip 

    Allen Hall: because you always wonder how serious some of these data center projects are because you hear the names like who?

    Uh, and the one that always gets me is, no, no offense to Stanford University, but. Lately, I’m hearing a lot of Stanford University graduates that are planning some massive power generation source of some sun type and just go, okay, no. Can we stop? Can we stop for a minute? No. Having a master’s degree from Stanford doesn’t know.

    You probably don’t know how to build a data center. Sorry. And you probably don’t know how to do distributed energy. You don’t. It’s just those are complicated and industrial things that take a lot of money and time and resources, so, no. So the, the reality of what is. Real that will be built, that’s gonna come due.

    I think there’s a lot of projects that were theoretical and grand and, uh, six months ago even are going to go kapoof, like pets.com. In 2001, it’s gonna be the same thing. 

    Nikki Briggs: You’re dating yourself, Alan. 

    Allen Hall: There was a time when. [00:20:00] When everybody was gonna be, be a internet billionaire, and one of ’em was pets.com, right?

    So pets.com was this pet store thing, and, and it was, they had a great URL of course, but as soon as, you know, there was any e you know, the, the, the, the, uh, planes hit the towers in New York City, poof, that thing was gone and they could sustain the, the economics of, um. The US at the moment, and when I think of Austin, I think all the tech bros are in Austin.

    Like you drive around Austin, you just see it. There’s a lot of smart people on the ground trying to do these grandiose things. Electricity generation is a hundred and twenty five, a hundred forty years old. That is an industrial process that is really hard to break into and you can’t AI your way into creating data centers.

    Does somebody realize that? And was the GE talk today? I’m gonna be the GE talk today, Yolanda, on the gas turbines. Obviously [00:21:00] they wanna take as many orders as they can or get place placeholder deposits in one of the GEs competitors is not even taking orders past 2030 ’cause they don’t think they’re real if they were real.

    I think everybody taking orders and I think they’re, they’re seeing the quality of that individual walking in the door trying to place, place that deposit and realize. They don’t know how to work EPC. 

    Yolanda Padron: Have you seen, I know there’s, there’s been a lot of like memes right now about how the use of electricity in AI and data centers and it’s like, you know, we’ve increased exponentially, so we will continue increasing exponentially until the end of time.

    Allen Hall: Till the world explodes. 

    Yolanda Padron: Yeah, exactly. And it’s like, I don’t think, I mean, to your point, like I, is it real like it. It could, it was sort of, um, it did grow a lot and it’s continuing to grow a lot. I just don’t know that it’s gonna be something where like everybody has a data center in their backyard, or everyone’s connected to a data center within a mile.

    You [00:22:00] know, 

    Allen Hall: I think you’re a hundred percent right about that. So the realism is hitting the market, right? So as PPA prices increase and the realities of construction projects hits everybody, this is gonna slow down. Quite a bit. 

    Yolanda Padron: I’m curious to see how long that’ll be before we overshoot it for the PPA prices.

    Allen Hall: Oh, you think, okay. That’s a, that’s a really good point because I, I was wondering that today, I’ve been telling people for two years now, as soon as they, uh, the tax credits sunset that PPA prices necessarily have to go up, they just have to go up the, the, the offshore wind PPA prices, were in the $150, uh, megawatt hour.

    Ballpark, uh, for a couple of projects off the coast in New York. I don’t know what they are in Europe at the minute. I, I should go look. I do actually do know. I should go back and look though. But the onshore prices are obviously much less, right? If you’re in the $80 per megawatt hour, although it does seem high, it is relatively [00:23:00] low compared to everything else you’re gonna be able to do.

    What, what are the choices you’re gonna do? What other, what other choices can you make? 

    Yolanda Padron: What kind of structure are you gonna. Work with is if you’re increasing, increasing, increasing, and then eventually we’re gonna hit a plateau eventually, or like an almost plateau. But I highly doubt everyone’s gonna be able to forecast exactly when that is without overshooting it.

    Allen Hall: Yeah. I guess the question is how much is the overshoot. Is it a hundred dollars? Is it $120? Is it $150? 

    Nikki Briggs: I have a question though, because are these AI data centers, are they meant to be running completely on wind power? 

    Allen Hall: They in theory can’t. Right? 

    Nikki Briggs: They need power 24 7. So 

    Yolanda Padron: yeah, they need to have some sort of backup thing, so maybe even backup in the grid or something if it’s not something directly hitting it.

    A lot of projects are like co-located, so you might have wind and battery or wind solar battery or something. All together, 

    Allen Hall: the XAI effort in Memphis, right? There’s, it is gas turbines, a bunch of gas turbines they’ve bought from [00:24:00] all over, but it has a pretty good best backup to provide stability to that.

    I think you’d have to do that, right? 

    Nikki Briggs: You’d have to have a a, a failover plan or something. Yeah. 

    Allen Hall: Having watched the internet and at different times of day, there’s nothing happening between like us time midnight and 6:00 AM. There is zero going on, and I always think does 24 7 AI data center need is so not gonna happen because when people are, if, if the data center is providing roughly national, or say it’s Europe, there’s, there’s, people are awake as a certain time of day and then they’re not.

    Right? So unless your data center’s gonna feed China, which it won’t, and Europe at the same time, or the US and Europe, it’s still, there’s just blocks of time where the. You just don’t need a lot of power. You just don’t need it. So the 24 7 demand, I think is not real 

    Nikki Briggs: well, but they have to keep them cool.

    And you [00:25:00] know, I mean there’s like the environment inside of the data center has to be a certain, uh. Uh, specification, I guess. Right? One question that I, that I had come up here on the side, Alan, had you heard about the, uh, CEO from Vestas talking about the need for an energy union? 

    Allen Hall: Yes, but this is not the first time it’s come up, uh, to, to try to, to gather everybody together.

    Ideally, if you’re thinking about the eu. Working together, and rarely does that happen, but if it were to happen, Vestas would be a huge winner in that. So would Siemens esa Honestly, the, the weird thing about all what’s happening in Madrid and at, when Europe at the moment is that sizzle’s back and they’re talking about doing projects in Europe and uh, I think a Donny is also talking about doing projects in Europe or providing turbines, right?

    So there’s. [00:26:00] Once Ming Yang was rejected in Scotland, which I thought was inevitable, I’ve always thought that the second place to go to get turbines that would compete with Avesta and Siemens is in India, and I do, because it’s an English speaking country, it does break down a lot of barriers. That’s for sure.

    And because obviously it was a, a, a British colony for a long time, there’s the relationship there. That would be it. It, I think something that makes, makes sense. So Vestus, who would obviously be the winner of all the offshore and maybe even some of the onshore projects in the UK may have competition. So although Vestas may be hoping for more of a energy block, which.

    Uh, could work, honestly. It could work and you could see a lot of wind and solar and batteries and hydro in, in Europe and obviously France with nuclear. I think [00:27:00] India has a really good shot at penetrating that market that would change the dynamics quite a bit. That would put pressure on Vestas to lower prices, no doubt.

    And so the, the, the dream scenario of Vestas is the only. OM standing in this huge demand market, which is all local to them. Uh, that may not actually turn out there. There could be some really rough patches here. If, uh, the so salons, a Donnies of the world, they can produce a five megawatt, six megawatt turbine.

    God knows if they could make a a 15 megawatt offshore turbine, that would put a tremendous amount of pressure on Vestus. Tremendous, and that would be harder to stop. I think from a a UK standpoint, very interesting times. Vestus is well suited to, to gain market share and is rapidly in the United States and a number of other countries, Australia being another, and Europe, but woo.

    Huh. The dream scenario never works out like you think it [00:28:00] will. It never does. As wind energy professionals, staying informed is crucial, and let’s face it difficult. That’s why the Uptime podcast recommends PES Wind Magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future.

    Whether you’re an industry veteran or a new. Wind, PES Wind has the high quality content you need. Don’t miss out. Visit PES wind.com today. So there’s been more information come out about the, this Iberian blackout that happened about a year ago. And as the, the details are, uh, published and everybody has a chance to review them, uh, one, one person to check out is, um.

    Howard Pinrose at Motor Dock and his chaos in Caffeine podcast, which happens on the weekends because he provides some good summaries about some of the latest news from the Iberian Peninsula and the reports that are being published. [00:29:00] The Iberian blackout and the role of renewables is very interesting.

    The, the problem that they had was, uh. Instability. So it, the grid was just generally unstable and they had a transformer fail and that just cascaded where, uh, they were disconnected from the rest of Europe. So the Liberian peninsula was just automatically disconnected and that happened relatively quickly.

    One of the things that could have supported the grid, and I think you’re gonna see changes happening, and Howard Pinrose was just in Washington DC with American clean power pushing for this, which is. As Yolanda knows, solar and wind have sort of two moats. They can follow the grid and produce power and just kind of follow along.

    Or better yet, they can form the grid and support the grid and be a resource when things get wobbly on the grid. And Spain learn that lesson really [00:30:00] well about a year ago, and I think we’re gonna find that all those solar panels that disconnected and because you’re in a following mode, protect mode. If they had had ’em in a, a more, uh, command role into managing the grid, that maybe the Iberian peninsula may not have blacked out.

    Maybe parts of it had because they lost a transformer, but there may be a role for renewables in terms of grid stability. Doesn’t that seem odd? Because the story and the mis, maybe the misinformation that’s happening around the world is, well, if the wind turbine isn’t turning, it can’t help monitor the grid.

    It actually can, same thing for solar. Those inverters that sit on the grid are actually thinking and working and reacting. So they can actually provide a lot more, uh, stability to the grid than maybe be some other resources at, at a lot less cost. Is there a scenario where we start changing the rules about wind and solar where we, instead of them playing dumb, that they become smart [00:31:00] and provide more stability?

    Yolanda Padron: Well, it happens a lot I think in Texas, right? We have, like you, you dispatch wind when you need it and you dispatch solar when you need it. And there’s a whole, I mean, the whole market. Behind the scenes that it’s for people a lot smarter than I am. But, uh, but yeah, I mean, you, you get, like, you’ll see sometimes wind turbines that are pitched slightly so they won’t generate electricity when it’s not needed, or they’re just free flowing when, I mean, it’s, it’s not necessarily to produce a lot of electricity or, you know, sometimes you’ll say, oh, you know what, I need this much.

    Energy from you at this moment, and so Sure. Switch. I mean, it’s, it’s literally a click of a computer. You turn it on, make sure the, that it’s dispatching energy, and then once you need it to be cut off, it’s cut off. Especially if it’s a co-located site, it’s a lot easier to make sure that you are [00:32:00] actually giving all the energy that you need to give in any given moment.

    Allen Hall: Because a grid reacts very quickly when things go wrong in the grid. It happens in seconds, and the only thing they can respond in seconds. Is renewables, inverter based resources. That’s the only thing you can respond. You can’t spool up a synchronous condenser to stabilize your grid in a couple of seconds.

    You may need a couple of hours typically to get that going. Isn’t this where we’re going? It because of the digital age and everything is on off so fast. If I had a data center that, you know, it collapses pulling a gigawatt, man, you need to be react almost instantaneously to that. The only thing that can do it today if they chose to do it is wind, solar, and battery.

    That’s it. In the digital age, 

    Yolanda Padron: I think it’s great. There was this one time, uh, a few years ago where, um, uh, a, a buddy who’s, who was a, a traitor for, you know, the, the, uh, energy markets in the [00:33:00] states. Um, he, he saw what was happening and he knew that he could. You know, he was controlling like wind, solar, and, and battery.

    And it was a co-located solar and battery site. And so he let them dispatch the solar for a bit and then he held off on the battery. And then the moment that he dispatched it was like he. Within like five minutes, it was $3,000. Something crazy like that. ’cause it was just like the mo, like he was just, everybody was amazed.

    Just the moment that he was like, amazing. Just like, well this is, this is why you do what, what you do. You know? Um, but yeah. Yeah, it’s, I mean, it’s a really, it’s a really interesting, interesting, for anybody that wants to read up on it. Like the, the market for that is really, really interesting. 

    Nikki Briggs: It does sound really interesting and like, I’ve been thinking a little bit about, um.

    The, the role of wind and, and you know, in Colorado we have a lot of high wind and then we have this [00:34:00] wildfire danger as well because of the drought. And so what happens when it gets really, really windy is they turn off the power ’cause they don’t wanna start a fire, a wildfire. So, um, so you know, here you want the wind so that you can generate the power, but then you can’t give it.

    So how do you store that and how do you, you know, like how do you manage that, you know? It’s a, it’s a tricky situation. 

    Yolanda Padron: Yeah. That’s where they’re co-locating. I think a lot of sites, there’s a lot of, I know there’s a wind farm in Arizona that’s really huge and they have a, a whole, they have a certain perimeter around it where they just really make sure that there’s nothing that can spread there.

    Like it’s, it’s just. Kind of barren land, so in case there is a wildfire or anything, ’cause it’s in a very dry area. Um, nothing will really happen to that in theory, you know, that has all the systems for the battery. 

    Nikki Briggs: What if the, what if the electric transmission lines are what, you know, causes the fire [00:35:00] because of the wind?

    The wind is causing those to break or to fall down. The poles fall down and then they cause a spark. And then they cause a fire. That’s what happened in Colorado a long time ago, a couple years ago. 

    Allen Hall: Same thing in California. 

    Nikki Briggs: So in order to protect from that, there’s like, it’s super windy. So they turn off the power.

    Allen Hall: Does it make it right? Right. Well this, this comes back to the infrastructure of the United States and how old that it is, and if you pay attention as you drive across the US you’ll realize that some of the. Towers and some of the infrastructure that you see on the side of the road. Dang, you’re a hundred years old and it doesn’t get replaced.

    It was never meant to be replaced. Or maybe they thought we were gonna be living on Mars in a hundred years, but basically it’s the same. Technology. It’s a wire on a kind of suspended up there in the air, and the wind moves around and it’ll burn and it wears out. It just wears out, right? Eventually you’ll just wear through that stuff, and we’re seeing that [00:36:00] across the United States.

    You’re seeing it in Europe, you see it in Spain, in other places where the infrastructure has just has a lot of age on it until we decide to do something new and refurbish it, like we refurbish the roads all the time. Uh, we’re gonna have trouble. We just are gonna have trouble in the states. 

    Yolanda Padron: Alan, as an electrical engineer, I do have a question.

    So would the forecasted generation needed by all these data centers and stuff, like with our current system, would we be okay with that? Or what kind of changes would we need to make just as a country in general? 

    Allen Hall: I think the problem with. A large data center as you’re seeing some of them being built on the east coast right now is one, trying to keep them up and running.

    Two, the infrastructure that are feeding and it’s old, right? So the transformers and all that. The things that don’t move, that are just planted on a concrete pad [00:37:00] that’s seem like they, they would never age, age, had fail. Eventually. So when you put a big demand on existing infrastructure that’s kind of powering old light bulbs and um, motors and things that are old and that have very well-known patterns, and you start putting these, uh, basically big digital power sinks that go up and down in in power usage.

    The grid can’t take that. It just won’t be able to take it at scale. It’ll take it for a while and we’ll figure out a way because electrical engineers tend to be pretty sy um, at how to make miracles out of, uh, uh, uh, of questionable things. That’s how we, how we do that, that’s why we get paid so much. But the, the, the problem is, is that at some point it’s gonna break, right?

    And, and the, the electrical grid in the US and the people that support that. Internally, I think we’re getting a little bit worried about it [00:38:00] and trying to figure out what we can do to keep the grid up and running. It’s a huge problem, huge problem, because when the grid was built back in the late 18 hundreds, early 19 hundreds, there were a lot less people, and somehow we managed to get to about 350 million people.

    All with the mobile phones and big screen TVs, and now electric vehicles and laptops, and blahdy, blahdy, blah. How this thing is still running is a miracle. It really is it. It obviously is

    Yolanda Padron: delamination and bottom line. Failures and blades are 

    Allen Hall: difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. C-I-C-N-D-T are specialists to detect these critical flaws before they become expensive burdens. Their non-destructive test technology penetrates deep into the label materials.

    To find voids and cracks. Traditional inspections completely. Miss [00:39:00] C-I-C-N-D-T Maps. Every critical defect delivers actionable reports and provides support to get your blades back in service. So visit cic ndt.com because catching blade problems early will save you millions.

    So G Renova was ordered by the courts just recently to stay at Vineyard Wind. Vineyard. Wind had. Filed a complaint that, um, GE was gonna leave the site, uh, off the coast of Massachusetts at the end of April. That obviously caused some concern with vineyard winds, so they went to court, sort of bypass the arbitration process.

    According GE went straight to court to get an injunction to prevent GE from moving on. Well, they have that injunction now, and GE has to stay on at least for about the next 60 days. If I read this right. Then there’s gonna be more court proceedings. GE is trying to get it back into arbitration where they can do some negotiation, but it’s all about big, big dollars.[00:40:00]

    The one thing that came out with Scott Straza, uh, Q1 discussion, which was uh, a phone call today, had to do with the completion of GE Ver Nova’s offshore wind projects, and when they could be complete. That includes sort of the doer bank projects in the uk, which I think are gonna wrap up sometime in 2027 to try to get those finished and vineyard wind, which they said was gonna be finished at the end of April.

    So from a GE Renova standpoint, I think they’re considering vineyard wind to be done at the end of the month and that’s gonna be their position. It was very odd. To hear the CEO of GE Renova talk about something that’s in litigation. ’cause usually that doesn’t happen. But if the company position is, Hey, we’re leaving at the end of April, we’ll see you a vineyard wind.

    That’s a problem. And let me explain a little bit of the details of this. GE Renova is based in Cambridge, Massachusetts, not that far away from vineyard wind, which [00:41:00] is also based in Massachusetts. So you have this corporate entity, which just. Opened an office in Cambridge. It’s really swanky place, not very far from where MIT and Harvard and all the, the elite universities are just outside of Boston.

    And then you have this vineyard wind project, which is important to the state of Massachusetts where they need that power to happen and they need it to be sustained and needed to run properly inside the state of Massachusetts. There must be huge discussions about this in the state government. Massive discussions about how these two entities have to work together for the next 20 years, and they are really at each other’s throats.

    That’s not the way you wanna start an offshore project. And Yolanda, you’ve been around some of these offshore projects. Is it always this tense between the OEM and the operator? Is, is this where all these projects end in some sort of disagreement and [00:42:00] separation? 

    Yolanda Padron: No, I think, I mean, from my experience.

    There’s usually someone at some point, and it’s usually, I think, I mean the. The owner, but you’ll stop and say, okay, I need to work with this person. I need to work with this company for the next X amount of years. I need to make sure that they give me the proper documentation once I need it. I need to make sure that they’re doing things in good faith.

    You know, I mean, if I can’t, it’s not like the technicians have like a camera strapped onto them to, so you can monitor every single blade repair, right? Like you need to make sure that they’re doing things right. Um, and not just patching things up because. Because they’re mad at you. Uh, so, so, no, I think it’s, it’s a little bit crazy to me that no one’s yielding as much.

    Allen Hall: I think GEs position is we’re gonna give vineyard all the manuals and the equipment would be up and running. You can find somebody to run it. You, you, you think that’s possible On a brand new turbine that [00:43:00] is only one other places on the planet that’s being run, which is over in the uk. Are you gonna be able to find people if GE walks off?

    Yolanda Padron: I mean, even if you can find people, once GE walks off, it’s like you, you need to be able to train your technicians. You know, like all of these, all of these projects are you, you need to have them in constant supervision. You need to make sure that everything’s working smoothly and you can’t just afford, I don’t know if we’re being really optimistic, like a month of no one touching those turbines.

    That’s crazy. Like anybody in the wind world is even onshore. Could you imagine if we just walked off a site and just let the wind turbines just be for a month? Like that’s, I mean, I don’t know, I, I’m not super, super well versed in exactly what they’re getting, but are they getting any sort of, at least like technical support?

    Allen Hall: I don’t think so. No. Yeah, 

    Yolanda Padron: no rock system, no. Nothing. 

    Allen Hall: If it all works out like GE wants it to, [00:44:00] no. You get the manuals. You get a, a, a nice, uh. Card in the mail saying Thank you for your business. And that’s it. It, that’s, I think that’s where it’s going. 

    Nikki Briggs: Doesn’t seem like a good way to, like, doesn’t seem like they’re stand standing behind their product or what they sold.

    Um, I mean, and it seems like there would be some downstream ramifications for other, other companies that want to buy ge. 

    Allen Hall: They don’t wanna be in that business. I, I think that’s one of the discussion points that never comes up when the quarterly calls is. Is GE gonna remain in the wind business? Because I think the answer to it is maybe how could a lot, I mean, you said on the financial side of some of these, uh, wind farms and paid attention to the details.

    If you were losing a billion dollars a year, how long would you be in that business? 

    Yolanda Padron: I mean, not very long. I think you’d have to change things to make it work. Um, yeah. I mean, I don’t know. I think, [00:45:00] I think it’s one of those things where they’re trying to. Find exactly where they fit into this business, if they still fit in at all.

    Uh, I really hope they don’t fully back out because of everyone that’s in operations that has GE products out there that’s really gonna need that support. Uh, I think especially for a vineyard’s sake, at the very least that they’ve are doing, that vineyard is doing a better job than a lot of the operators I know at making sure that.

    Everything you need within operations has been asked for since development and construction. Um, I’m not super, super optimistic about that. Just because like everyone has so many things to do that you don’t like if you’re in development, you don’t always have time to think about. Oh yeah, I really hope they give me the repair manuals in case there’s a lightning strike on the blade at R 20.

    You know, like it’s just, um, so it’s just. It’s, [00:46:00] it’s just gonna, it’s gonna be a very interesting case study. Whatever they end up doing, I think it’s gonna be something that will be worth following a bit more closely. We’ve seen, there’s been projects where, you know, day one, the OEM just backs off, but that was at least.

    They knew that, you know, the, the owner knew it two years in advance, and so they tried to get as many people as possible. There were to, to get on those turbines. There were of course mishaps and stuff, um, and it was more of a financial than an engineering decision. Um, but when the decision was made, people knew about it and people had time to act.

    I mean, people having a week to find, I. Someone to, to, to take care of every single aspect of their site is a little bit insane. Especially, I mean, [00:47:00]with the history of veneer, right? Like, come on, they had a, they had a blade break, 

    Allen Hall: right? There’s gotta be a lot of questions about the durability. There has to be Right.

    Even if, even if GEs figured it out, and I think they probably have, and then they’ve put a, a lot of money and time into resolving the issue. You still have to wonder. Is it right? And if you’re vineyard, I think that’s one of the questions is, is it right and could we operate it by ourselves without needing a lot of handholding from ge?

    Or paying GE more money than we already agreed to, which is probably what’s likely to happen, right? That GE iss gonna ask for more money if they can break the contract legally and renegotiate, that would be a smart move. I think they will try to do it. It’s unfortunate and it causes a lot of grief for a lot of people, but I think GE probably needs to renegotiate and probably Vineyard wants to renegotiate it too ’cause they both feel disgruntled at this point.

    Yolanda Padron: Yeah, and I think it’s really interesting ’cause we focus a lot on vineyard and just the [00:48:00] way that the OEM and the owner operated with each other just because it gets, it’s so close to such an important part of the country that gets so much PR all the time. It’s just, it kind of sets the mood for a lot of things that go on.

    So it’s, I mean, it’s not that we’re just picking a lot of vineyards, it’s just really, it’s a really important site just in general from where it is, right? It’s not like it’s in the middle of nowhere. It’s a very important place that gets a lot of attention

    Good Monday, everyone.

    This past week… some big things happened in Madrid.

    Fifteen thousand wind energy people from every corner of the world walked into the same room.

    They came to talk. They came to listen. They came to ask for help.

    And they came to warn.

    The WindEurope Annual Event opened on Tuesday, the twenty-first of April, with six hundred twenty exhibitors and four hundred speakers across three days.

    Spain’s Prime Minister Pedro Sanchez gave the opening address.

    Fourteen national ministers stood on the stages, alongside European Commission Executive Vice President Teresa Ribera and European Commissioner for Energy Dan Jorgensen.

    And the message coming out of Madrid… was a single piece of paper.

    They called it the Madrid Call to Action.

    Ten points. Ten things European governments need to do… right now.

    Fast-track permitting, and treat wind as overriding public interest. Award at least eighty percent of wind auction bids… no more artificial scarcity. Repower aging wind farms and triple their output with fewer turbines. Multiply EU grid funding by five. Zero VAT on heat pumps and electric vehicles. And permanently cut taxes on electricity… because homegrown power should be the cheapest power.

    The framing was simple.

    From crisis… to confidence… in a decade.

    But while the speeches were polite… the panels were not.

    On Thursday afternoon, Vestas chief executive Henrik Andersen took the microphone, and he did not mince words.

    Andersen called it mission impossible.

    He told politicians to stop submitting wish lists for new auctions. He pointed at Denmark’s recent failed offshore auction… an auction that no developer would even bid on. And he pointed at countries trying to build a three-dimensional CSRD into the next tender.

    Then he delivered the line that quieted the room.

    If we don’t get this under control… we’ll be sitting here in five years… begging to keep the lights on.

    Now… while the warnings were echoing through Madrid… something quieter was happening on a balance sheet in Munich.

    Siemens Energy released preliminary second-quarter results on Wednesday, and then raised their full-year outlook.

    Group orders for the quarter came in at seventeen point seven billion euros… up almost thirty percent year on year.

    Net income for the full year is now expected to be around four billion euros, with Grid Technologies orders alone up forty-one percent.

    And the wind unit… Siemens Gamesa… their losses narrowed to forty-four million euros.

    A year ago, that number was two hundred forty-nine million.

    Still in the red. Still operating at a margin of negative one point seven percent. But the trend is clear.

    The Spanish wind unit is closing in on break-even.

    After years of crisis… after billions of euros in impairments… Siemens Gamesa is healing.

    Now back to Madrid.

    Because last Thursday, WindEurope published a different kind of paper.

    Not about money. Not about megawatts. About sabotage.

    Across Europe’s seas, energy infrastructure has become a target. Cables, substations, offshore platforms… spread across thousands of square kilometers of open ocean… difficult to protect.

    WindEurope Chief Executive Tinne Van Der Straeten said it plainly.

    The physical security of Europe’s wind turbines must be treated as an integral part of energy security… not as an afterthought.

    The policy paper calls for civilian protection, not military. Risk-based and proportionate, with clear cost allocation between government and industry.

    Wind farms now generate twenty percent of Europe’s electricity, and the North Sea countries have pledged three hundred gigawatts of offshore wind by twenty fifty.

    That is a lot of critical infrastructure… sitting in the open ocean.

    But here is where Madrid got uncomfortable.

    Vestas’ senior vice president stood on a panel Wednesday afternoon and offered a reality check.

    The EU has set a goal of twenty-two gigawatts of new wind installation every year through twenty thirty.

    What is the reality?

    The EU installed fifteen gigawatts in twenty twenty-five. Sixteen the year before.

    There is a gap… between political will, goals, and promises… and the reality we see in the market.

    The Madrid Call to Action wants to close that gap.

    The paper exists. The politicians have been told. Now… we wait.

    And while the speeches were happening in Madrid… a small Danish company was quietly opening doors in Asia.

    CNC Onsite… a wind sector subsupplier… signed two deals this month.

    One with Dutch firm WE4CE for Thai customer Cewa Plus, a deal that opens twelve Asian countries.

    The technology? A specialized machine that drills out the steel bushings holding a wind turbine blade to the hub, so they can be replaced without scrapping the blade.

    Repair on site. Save the blade. Extend its life.

    The second deal… a CNC milling machine sold into Japan for offshore monopile and foundation work.

    CEO Soren Kellenberger says the combined opportunity could deliver up to fifty million Danish kroner in revenue… roughly six point seven million euros.

    Not big numbers. Not yet.

    But while everyone in Madrid was talking about politicians… CNC Onsite was signing contracts in Bangkok and Tokyo.

    The number of wind turbines reaching the age where their blades need replacing… Kellenberger calls it… huge.

    So let us step back.

    In Madrid, fifteen thousand people gathered. A ten-point plan was published. A CEO warned of mission impossible. A trade association said the offshore turbines need physical protection from sabotage.

    In Munich, a balance sheet showed the wind business is healing… slowly, quietly, quarter by quarter.

    And in Bangkok, a Danish technician was teaching a Thai partner how to drill out a steel bushing.

    Six stories. One week.

    The wind industry showed up… asked for what it needed… and put the numbers on the table.

    The financial proof is starting to come. The political follow-through… we wait.

    And that is the state of the wind industry for the 27th of April… 2026.

    Join us for the Uptime Wind Energy Podcast tomorrow.

    Welcome to Uptime Spotlight, shining Light on Wind. Energy’s brightest innovators. This is the Progress Powering tomorrow.

    Allen Hall: Nicholas, welcome back to the show. 

    Nicholas Gaudern: Thanks, Allen. Always a pleasure. 

    Allen Hall: Well, there’s a lot of new products coming outta PowerCurve. And PowerCurve is the aerodynamic leader in add-ons and making your turbines perform at higher efficiency with less loss. Uh, so basically taking that standard OEM blade and making it work the way it was intended to work.

    Nicholas Gaudern: Yes. We 

    Allen Hall: like to 

    Nicholas Gaudern: think so. Yeah. 

    Allen Hall: And there’s a, there’s a lot of new technology that you’ve been working on in the lab that you haven’t been able to explore to the, introduce to the world, so to speak. Yeah. And we’ve seen some of it from the inside of, you know, you’re working behind the scenes or working really hard to get this done, but now that technology has been released to the world, and we’re gonna introduce it today, some new trailing edge.

    [00:01:00] Components. Yeah. That really, really reduce the noise. But they, they look a little bit odd. Yes. There’s a lot of ADON dams going on with 

    Nicholas Gaudern: Yeah. 

    Allen Hall: With these. So what, what do you call these new trailing edge parts? 

    Nicholas Gaudern: So, so what you have in your hand here? This is the Silence edge, uh, serration. So this is our new trailing Edge Serration products.

    Now, most people, when they think of training restorations, they are thinking of triangles. 

    Allen Hall: Exactly. 

    Nicholas Gaudern: These Dino tails. Dino Tails, that’s the Siemens, Siemens name for them. Pretty, pretty standard. You see ’em on a lot of turbines now. Sure. And they work, you know, they do do a job. They do a job. They reduce noise.

    But like with lots of things in, in aerodynamics, there’s lots of different ways that you can solve a problem and some are better than others. So we’ve worked for a long, long time in the wind tunnel, uh, in the CFD simulations, and we’ve come up with this pretty unique shape. We think, 

    Allen Hall: well, the, the, the shape is unique and if you, if you look at it, there’s actually different heights to the, the triangle, so to speak.

    To mix the air from the pressure and the [00:02:00] suction side to reduce the, the level of noise coming off the blade 

    Nicholas Gaudern: e Exactly. So we have, uh, we have an asymmetry to the part. We have these different tooth lengths. We have, uh, a lot of changes in thickness going on across the part. So it may be a little bit difficult to see on the camera, but these are quite sculpted 3D components.

    They’re not, they’re not flat stock white triangles. No, no. There’s a lot of thickness detail going on here. We’ve paid a lot of attention to the edges. We’ve paid a lot of attention to these gaps between the teeth as well. So all of this is about trying to figure out what is the best way to reduce noise.

    And something that not a lot of people will, will admit, but it’s true, is that as an industry we don’t really understand the fundamentals of how serrations work. 

    Allen Hall: It’s a complicated 

    Nicholas Gaudern: problem. It’s a really complicated thing. Problem, yeah. Yes. So trying to simulate it in CFD is an absolute nightmare. The, the mesh sizes required, the physics models required are really, really difficult.

    So what we found is that you’re probably better off spending [00:03:00] most of your time and money in the wind tunnel. Yes. So, so we go to DTU, they have this wonderful, uh, air acoustic wind tunnel, the pool of core tunnel. It’s one the best tunnels in the industry for doing this kind of work. It 

    Allen Hall: is 

    Nicholas Gaudern: because you can measure acoustics and aerodynamics at the same time.

    So this allows us to do a lot of very cost effective iteration for this kind of design work. So we know what’s important. You know, we’ve, we’ve studied all the different parameters of serrations lengths, aspect ratios, angles, thicknesses, all this kind of stuff. And it’s about bringing them together into a, into a coherent product.

    So this is, this is a result of a lot of design of experiments, a lot of iteration, and combining wind tunnel and CFD to kind of get the best of both of those tools. So, 

    Allen Hall: so what’s the. Noise reduction compared to those standard triangular trailing aerations. Yeah. 

    Nicholas Gaudern: So there’s lots of different ways of, of thinking about noise reduction, but I think probably the most useful is the O-A-S-P-L.

    So this is the overall sound pressure level. Right. Is kind of what [00:04:00]typically you’ll be measuring in an IEC test. 

    Allen Hall: Right. 

    Nicholas Gaudern: And that’s measured in decibels, but a way to decibels because it’s important that we’re waiting to what the human ear can actually hear. Right. Perceive. Exactly. So that’s the numbers we report.

    For the field test we’ve recently completed with Silent Edge, we’re seeing up to five decibels of O-A-S-P-L noise reduction. 

    Allen Hall: Okay. So what’s that mean in terms of what I hear on the ground? 

    Nicholas Gaudern: So that is an absolutely huge reduction. It’s multiple times of reduction because you know, decibels on a log scale, 

    Allen Hall: right?

    Nicholas Gaudern: So five DB is is enormous. It’s 

    Allen Hall: a lot. Yeah. 

    Nicholas Gaudern: And what’s really interesting is that if you have a turbine that’s running in a noise mode, just one decibel reduction. Of power, sound, sound, power level might be three or 4% P loss. I mean, that, that’s, that’s huge. Think about that loss. So if you need to reduce noise by five decibels to get within a regulation, imagine how much a EP you have to throw away by basically turning down the [00:05:00] turbine to do that.

    Allen Hall: That’s right. 

    Nicholas Gaudern: So that’s really what the, the business case for these kind of products is. It means you can escape noise modes because as soon as you use a noise mode. You are throwing away energy. 

    Allen Hall: You’re throwing well you’re throwing away profits. 

    Nicholas Gaudern: Exactly. 

    Allen Hall: So you’re just losing money to reduce the noise.

    Now you can operate at peak. 

    Nicholas Gaudern: Yep. 

    Allen Hall: Power output without the creating the noise where you have that risk. Right. So, and particularly in a lot of countries now, there are noise regulations. Yes. And they are very well monitored. 

    Nicholas Gaudern: Yep. 

    Allen Hall: We’re seeing it more and more where, uh, government agencies are coming out and checking.

    Yes. ’cause they have a complaint and so you get a complaint. Oh, that’s fine. Or someone can complain. Yeah. You know, you need to be making your numbers. 

    Nicholas Gaudern: Yep. And, and the industry needs to be good neighbors, you know? It 

    Allen Hall: certainly does. 

    Nicholas Gaudern: Uh, we have to make sure that people are, you know, approving and comfortable with having wind turbines in their backyard.

    Sure. And noise is a big part of that. 

    Allen Hall: It is. 

    Nicholas Gaudern: So yeah. Ap sure. That’s really important. Being a good [00:06:00] neighbor also important. 

    Allen Hall: Right. 

    Nicholas Gaudern: Meeting the regulations. Obviously you have to meet the regulations. So this product, um, has been through a really long development cycle, and we’re now putting the final touches to the, to the tooling.

    So this is available now. 

    Allen Hall: Oh, wow. 

    Nicholas Gaudern: Okay. Great. Um, and we’re hoping that in the next uh, few months we’ll be getting even more turbines equipped out in the field with, with the technology. 

    Allen Hall: So, oh, sure. There’s a, you think about the number of turbines that are in service, hundreds of thousands total worldwide.

    A lot of them have no noise reduction at all. 

    Nicholas Gaudern: No. No. 

    Allen Hall: And they have a lot of complaints from the neighbors. 

    Nicholas Gaudern: Exactly. 

    Allen Hall: Trying to expand wind into new areas, uh, is hard because the, the experience of the previous Yes. Neighbor 

    Nicholas Gaudern: Yep. 

    Allen Hall: Grows into future neighbors. So fixing the turbines you have out in sight today helps you get the next site.

    I know we don’t always think about that, but that’s exactly how it works. Yeah, of course. Uh, we need to be conscientious of the people of the turbines we have in service right now. So that we can continue to grow wind [00:07:00] globally and more regulations on noise are gonna come unless we start taking care of the problem ourselves.

    Nicholas Gaudern: Yep. And another really important thing with Serrations is that you have to design them so that they don’t impact the loads on the rest of the turbine. 

    Allen Hall: Right. And people forget about that. 

    Nicholas Gaudern: Yes. 

    Allen Hall: Can you just, can’t just throw up any device up there. And think, well, my blade’s gonna be happy with it. It may not be happy with that device.

    Nicholas Gaudern: You have to really carefully understand what the existing blade aerodynamic signature is. 

    Allen Hall: Sure. 

    Nicholas Gaudern: How is that blade performing? What is the lift distribution across the span? Yeah. 

    Allen Hall: Right. Yeah. 

    Nicholas Gaudern: So what we do, and we, we’ve talked about it before we go and laser scan blades. We build CAD models, we build CFD models so we can actually understand how much lift a blade can take and what’s the benefit or the penalty of doing so.

    So these serrations are designed by default to be load neutral. They won’t increase lift. They won’t reduce lift. That’s what 

    Allen Hall: it should 

    Nicholas Gaudern: be. That’s where you should start, 

    Allen Hall: right? 

    Nicholas Gaudern: And maybe there’s some scope to do something else [00:08:00] on certain turbines, but you shouldn’t, you shouldn’t guess. You, you need to calculate, you need to simulate, you need to think very carefully about that.

    So that’s what we do with these, uh, with these serrations, we go through this very careful aerodynamic design process to make sure that they reduce noise and that’s it. They don’t increase loads, they don’t reduce AP by killing lift. And that’s, that’s an important aspect. 

    Allen Hall: Well, that’s the goal. 

    Nicholas Gaudern: Yes, 

    Allen Hall: exactly.

    I don’t necessarily want to increase power. I don’t wanna put more load in my blade, but people do that. I’ve seen that happen and man, they regret it. 

    Nicholas Gaudern: Yeah, regret it. There’s, there’s some pretty wild claims out there as well about observations can and can’t do. And uh, like with lots of things, it’s important to just do the simulations, speak to some experts and, um.

    Yeah, maybe take the, the less exciting path, you know, sometimes, 

    Allen Hall: well, no. Yeah. Well, less exciting path where I don’t have a broken blade. 

    Nicholas Gaudern: Yeah, exactly. 

    Allen Hall: Yeah. That’s a lot less exciting. It’s, it’s definitely more profitable. Now, the Dragon Scale Vortex generator has been [00:09:00] around about a year or so. 

    Nicholas Gaudern: Yep, yep. 

    Allen Hall: And the thing about these devices, and they’re so unique, interesting to think about because you typically think of a vortex generator as this being this little bit of a fence.

    Where you are tripping the air and making it fall back down onto the blade. 

    Nicholas Gaudern: Yep. 

    Allen Hall: A really, it works. 

    Nicholas Gaudern: It works. 

    Allen Hall: But it’s it’s 

    Nicholas Gaudern: been around a long time. 

    Allen Hall: Yeah. Yeah. It, it does, it does do this thing. And they, they were, they came outta the aviation business. We use ’em on airplanes to keep air flow over the control surfaces so we can continue to fly even in close to stall conditions.

    All that makes sense. And airplanes are not a wind turbine. 

    Nicholas Gaudern: Yes. 

    Allen Hall: So there’s different things happening there. So although they work great on on aircraft, they’re not necessarily the most efficient thing for a wind turbine where you’re trying to generate power and revenue from the rotation of the blades.

    Nicholas Gaudern: Exactly. 

    Allen Hall: So this is a completely different way of thinking about getting the airflow back onto the blade where it produces [00:10:00] revenue. 

    Nicholas Gaudern: And what’s really nice is to actually see this together with silent edge, because historically, and maybe not even historically. Serrations VGs, they’re triangles. They work, they do a job.

    But that doesn’t mean you can’t do it in a different way. In a better way. 

    Allen Hall: Right. 

    Nicholas Gaudern: And that’s the same principles from applying with Silence Edge and Dragon Scale. We want to work the flow in the most efficient way possible. 

    Allen Hall: Right. You’re trying to get to an 

    outcome. 

    Nicholas Gaudern: Yeah, exactly. 

    Allen Hall: Efficiently. 

    Nicholas Gaudern: We want to, we want to target very specific things on the blade, and that’s where you can see there’s a few different styles of Dragon Scale that we have on the table here.

    We have some that are two fins. We have some that are three fins. We have different sizes, and this is because they’re tailored to different parts of the blade. So these three Fin Dragon scales, their focus is ultimate lift. We are creating a really powerful vortex through this combination of three air foils, if you imagine, um, the inside of a Turbo fan.

    You have these cascading air force. [00:11:00] You look at the leading edge slacks on an aircraft. You look at the front wing of a Formula one car. It’s that kind of concept. 

    Allen Hall: It’s like that, 

    Nicholas Gaudern: and it’s these air force that are cooperating with each other. 

    Allen Hall: Right. 

    Nicholas Gaudern: To end up with a more beneficial result. ‘

    Allen Hall: cause an air force by itself does a function, but when you combine airflows together in the right way 

    Nicholas Gaudern: Exactly.

    Allen Hall: You can really control airflow efficiently, less losses. More of what you want out the backside. Yeah, exactly. It’s, it’s the backside you’re trying to work on, on a VG or, or dragon scales. You’re trying to create this flow which gets the airflow back onto the blade to create power. We, 

    Nicholas Gaudern: we want as much attached flow as possible and down exactly down in the roots of a blade.

    We have to have really thick aerofoils, you know, blades about round. They’re basically cylinders. 

    Allen Hall: Yeah. 

    Nicholas Gaudern: And that, that’s essential, right? We have to have the blade take a lot of load into the root aerodynamically. They’re horrible. 

    Allen Hall: Yeah. 

    Nicholas Gaudern: So this is where these, uh, these powerful Dragon Scale VGs come into play because what they do is they’re [00:12:00] reenergizing the flow over the aerofoils, and they’re ensuring that that flow remains attached for much, much longer than if those bgs weren’t there.

    So down in the root, you’ll get significant boosts to the lift that those sections can generate. And what’s more lift? It goes to more torque, it goes to more power, goes to more a EP. So these dragon scale VGs in the root are there to boost, lift, and boost EP out on the tip of the blade. Things are actually a little bit different because it’s way different.

    You shouldn’t really have stall there to begin with if your blade’s been designed well. 

    Allen Hall: But if you have leading edge erosion exactly. Or some other things that are happening, you can have real aerodynamic problems. 

    Nicholas Gaudern: So yeah, as soon as you have erosion, uh, maybe your stall margin is not as big as you thought it was.

    You’re starting to get some significant losses of lift Yes out towards the tip of the blade. So that’s where these, uh, TwoFin uh, variants come in. So it’s still a dragon scale vg, it’s still the same concept of these cascading error foils. Yeah, but these are [00:13:00] designed for basically ultimate lift to drag ratio.

    Mm-hmm. So we don’t really want more maximum lift outta the tip. We kind of have enough, but what we do want is to keep stable attached flow and we want to do it for the less, uh, least drag penalty possible. So basically we want to get rid of as much parasitic drag as we can. These two fin dragon scales, we are seeing 25 plus percent improvements in lift to drag ratio.

    Compared to a standard triangle vg. I mean that’s huge. 

    Allen Hall: That that is really 

    Nicholas Gaudern: huge. 

    Allen Hall: That’s huge, right? Because people have seen these, uh, triangular VGs in a lot of places. And one thing I’m noticing more recently is that those VGs, because they’re so draggy, they tend to flutter and they tend to break in just off.

    Nicholas Gaudern: Interesting. 

    Allen Hall: So you’re having this failure mode because this thing is just blocking the air, getting the air to trip. 

    Nicholas Gaudern: Yeah. 

    Allen Hall: It’s not efficient. It does have its downsides ’cause it is. D definitely drag. Just face it, it’s it, is it a draggy [00:14:00] 1940s technology? That’s what it is. Where with the dragon scales, now we’re doing things a lot more efficiently and thinking about how do I get the airflow that the blade designer originally wanted?

    Nicholas Gaudern: Yes, 

    Allen Hall: because the blade designer, they’re really intelligent people. They’re, they’re sitting designing blades. But the reality is what you design is on an ideal airflow, and what you have out in service are totally different things. As, as it turns out, the shape of the airflow is not what you think it is because it comes out of the tool and there’s a lot of touching with by humans that are grinding on the leading edges and doing the things that have to be done to manufacture it.

    So you don’t really have an ideal blade when it comes out of the 

    Nicholas Gaudern: No. You 

    Allen Hall: never do factory. No, you never do. 

    Nicholas Gaudern: And it’s not polished either. 

    Allen Hall: It’s not polished. Right. So 

    Nicholas Gaudern: when you go to the wind tunnel, you have a perfect profile. Yes. And it’s polished. And it works basically. It 

    Allen Hall: works great. It 

    Nicholas Gaudern: works great. 

    Allen Hall: The theoretical and the actual match.

    Yeah. In reality they do. I think a lot of operators are not [00:15:00] connected with that reality of, Hey, that Blade should be producing this amount of revenue for me, and it’s not. And you hear that discussion all the time, particularly in the us. It should be producing this amount of power. I’m doing all the calculations.

    We are not producing that power. Why? The blade length’s saying, but the power’s not coming out of it. Well take a look at your leading edge, take a look at your yard full of shape and realize you’re going to have to do something like dragon scales to get that E energy. Exactly. Revenue back. 

    Nicholas Gaudern: You need to do a full aerodynamic health check.

    Basically you do. And see what are all the possibilities to improve my blade performance. And some of it is down to the fundamental shape of the blade, 

    Allen Hall: right? 

    Nicholas Gaudern: But some of it is down to blade condition. Yes. Blade Blade manufacturing quality. 

    Allen Hall: Yes. 

    Nicholas Gaudern: Uh, what kind of paint did they put on it? What day of the week was it made?

    And all these things can be compensated for by VGs and you’ll get more revenue out at the end. 

    Allen Hall: You say? ’cause what happens? The, the, the scenario which is hard to visualize unless [00:16:00] you’re an A and emesis, is that there comes on the suction side, and it should be, in a ideal sense, rolling all the way to the back edge of the blade and coming off.

    What happens is though, is that. When you get leading edge erosion is that the air flow actually separates. Yeah. 

    Nicholas Gaudern: It 

    Allen Hall: doesn’t 

    Nicholas Gaudern: always make it, yeah. 

    Allen Hall: Doesn’t make it to the back edge. Yeah. And so you can see that, especially if, if there’s dirt in the air, you can look on dirty blades, you can see where that separation line is, and a lot of operators have sky specs, images or Zeit view images, and then go back and look at the blades.

    It takes two minutes to go. I have 

    Nicholas Gaudern: particularly down in the root, you’ll see it. 

    Allen Hall: Oh, in the root all the time. You, you 

    Nicholas Gaudern: see it really clearly that that separation line 

    Allen Hall: all the time, you really see that separation line. I’m seeing it more and more up towards the tip. Interesting. That’s where the lightning protection, yeah.

    Systems sit. 

    Nicholas Gaudern: Yeah. 

    Allen Hall: I see a lot of airflow that is not front to back on the suc. Well, you 

    Nicholas Gaudern: have a lot of three dimensional flow out there. 

    Allen Hall: You do towards the tip you do. And you realize how much power you’re losing there. And I think operators are just throwing away money. 

    Nicholas Gaudern: Yeah, exactly. 

    Allen Hall: So you could [00:17:00] put dragon skills on it very efficiently, very quickly.

    Get that revenue back into your system and it’s gonna stay. So even if leading edge erosion happens, the dragon scales are gonna compensate for it. It’s gonna get the airflow back where it should be. 

    Nicholas Gaudern: Exactly. And the nice thing about this is, you know, we are building on well over a decade of upgrading turbines with aerodynamic components.

    Oh yes. So this technology stands on the foundations of all of that work. In terms of the materials, the work instructions. Um, the fatigue calculate, you know, everything 

    Allen Hall: Yes. 

    Nicholas Gaudern: Is built on thousands of installations that we’ve done. Yes. So, although it’s a new technology aerodynamically, it’s not really new in lots of sensors.

    Allen Hall: Well, I look at it this way. If you turn on Formula One today and look at what the new generation of cars running around as you look at the, that front. Yes. Uh. Fin. Yeah. What do I call it? Air foil shape in the front. It’s super complicated. 

    Nicholas Gaudern: The sculpting of the [00:18:00] surfaces is really impressive, 

    Allen Hall: right? There’s a lot of thought going into those surfaces versus you turn on a Formula One race or go on YouTube and look at a Formula One race from the 1980s.

    Yeah, it’s basically a piece. 

    Nicholas Gaudern: Yeah. 

    Allen Hall: To provide down downforce. That’s it. The aerodynamics wasn’t really there, so we come a long way and a lot of that technology that happens in Formula One that happens in aviation eventually rolls down into. Yeah. Wind. 

    Nicholas Gaudern: Exactly 

    Allen Hall: right. So we, we, although we are not designing Formula One style blaze today, we’re taking that same knowledge and information and we’re applying that back in.

    Nicholas Gaudern: Yeah. We’re 

    Allen Hall: secondarily we, 

    Nicholas Gaudern: which is a right thing to do. We’re taking, taking inspiration from all these different aerodynamic fields and, you know, picking the best 

    Allen Hall: Yes. 

    Nicholas Gaudern: From what’s available and just allowing ourselves to be a little bit more creative. 

    Allen Hall: Yes. 

    Nicholas Gaudern: And thinking outside the box a bit. There’s so many ways to do this as we’ve been saying.

    And the import. And the 

    Allen Hall: data’s there. 

    Nicholas Gaudern: The data’s there. Exactly. 

    Allen Hall: The data’s there because you’ve been at the DTU Yep. Uh, wind Tunnel, which also has the acoustic piece to it. Yeah. So you have measured data from a reliable source. [00:19:00] You have field data, and you know, you put all these together, you’re gonna get that improvement back.

    You’re gonna get your invest back, you’ll be more profitable. 

    Nicholas Gaudern: So Dragon Scale, focus on the AP. And that a EP will, uh, vary depending on the turbine. 

    Allen Hall: Sure. 

    Nicholas Gaudern: But we’ll assess the turbine and, and decide the best configuration, and then say silent edge. That’s the focus on the noise reduction. And we’re seeing up to five decibels OASP on the field.

    It’s, which 

    Allen Hall: is crazy. 

    Nicholas Gaudern: It’s even more That’s really good that we were hoping for, you know? 

    Allen Hall: Yeah. 

    Nicholas Gaudern: So we, we know this is gonna be a, a great product. 

    Allen Hall: It looks very interesting. 

    Nicholas Gaudern: It does. 

    Allen Hall: It does it. It looks complicated and you think air airflow is complicated. It’s a compressible fluid. It’s not easy to, to just assume it’s gonna do what you think it is.

    Yeah. You need to get into the tunnel. You need to replicate, you need to do all that work, which is expensive in time consuming. That’s why you go to someone like Power. Curver knows what they’re doing in the wind tunnel, knows how to measure those things and know when they’re getting nonsense. Out of their computer.



    Nicholas Gaudern: mean, you, you’ll pay thousands and thousands of [00:20:00] Euros dollars a day to run a wind tunnel. 

    Allen Hall: You will. 

    Nicholas Gaudern: You’ve gotta Absolutely. You’ve gotta turn up with your plan in hand, that’s for sure. 

    Allen Hall: Oh, oh yeah, yeah, yeah. And I think there’s a lot of assumptions because it, aerodynamics is hard. You know, you watch these blade spin around, you don’t realize how complicated these devices are.

    They are complicated. Those air force shapes we are running today have been through a lot of history, a lot of history to get to where we are now. Now we’re just gonna take him into the next generation. This, we’re bringing ’em into the two thousands. In sort of a 

    Nicholas Gaudern: sense, what I’m hoping to see is, you know, with the OEMs, some OEMs do it already, but it’s important to think about these components when you’re designing new blades as well, you should because then that will allow you a much bigger design space to work in.

    And 

    Allen Hall: a lot less customer complaints. 

    Nicholas Gaudern: Yes. 

    Allen Hall: Where’s my power? 

    Nicholas Gaudern: Exactly. You know, these products, particularly the VGs, are really important tools for PowerCurve robustness. And some OEMs have known this for a long, long time. 

    Allen Hall: Yep. 

    Nicholas Gaudern: And you’ll see VGs on most of their blades. Mm-hmm. Others not so much. And that’s a design choice.

    It’s a design philosophy. Um, and I think it may not [00:21:00] be the right one, you know? 

    Allen Hall: Well, I think the operators are asking to get the most out of their turbines. Yeah. Why shouldn’t they? They should be asking for that. 

    Nicholas Gaudern: I think for a, for a long time, and it’s not just in wind devices, like these have been considered, you know, band-aids fixes when you’ve, you’ve messed something up.

    But I feel that’s a really negative way to think about products like this. They’re doing something that the kind of raw air fall shape on its own cannot achieve. Sure. Oh no. Right. You know, you might be able to mold some interesting stuff. Uh, as part of the blade, it’s very difficult to, to recreate the kind of aerodynamic effects that these products, uh, have.

    Allen Hall: Right. 

    Nicholas Gaudern: So they shouldn’t be considered bandaids or fixes. No. They should be considered opportunities. And ways that you can maximize performance and unlock areas of the design space that previously weren’t accessible to. 

    Allen Hall: Sure. Every possible component that deals with fluid air is moving this way. 

    Nicholas Gaudern: Yes. 

    Allen Hall: Jet engines, you look at jet engine, how much more is going into those jet engines today in terms of this kind of [00:22:00] technology?

    Yeah. All the race colors, doesn’t matter what class, where it is, is all looking at this anything to do with aircraft, it’s all over this. 

    Nicholas Gaudern: Yeah, 

    Allen Hall: exactly. Or, or doing this today. It’s just wind that’s behind 

    Nicholas Gaudern: wind. Wind is 

    Allen Hall: significantly 

    Nicholas Gaudern: behind. No, 

    Allen Hall: it’s not magic. It’s proven technology. It’s 

    Nicholas Gaudern: just good engineering.

    Allen Hall: Well, it’s good engineering and if you call PowerCurve, they’re gonna help you under to to, to understand what you have today and what you could have tomorrow. 

    Nicholas Gaudern: Yes. 

    Allen Hall: And how this, these devices will improve your revenue stream. 

    Nicholas Gaudern: Exactly. You know, we will look at your blades, we’ll give you some good advice and maybe that advice will be that.

    You know, a certain product isn’t right for your blade. Right. That’s fine. 

    Allen Hall: That’s an answer. 

    Nicholas Gaudern: That’s an answer. 

    Allen Hall: Yeah, it is. 

    Nicholas Gaudern: But let’s, let’s look at the blade. Let’s see what’s possible, and let’s just have a, have a proper conversation about it over some real data, some real 

    Allen Hall: facts. Right. I think that’s the key, and a lot of operators are afraid to talk about aerodynamics is it’s, it’s a difficult area to, to start the conversation on, right?

    Yeah. But I think at the end of the day, when I work with PowerCurve, and I’ve worked with you guys for a [00:23:00] number of years, the answers I get back are intelligent and they’re not. Super complicated. This is what you’re gonna see. This is the improvement. And then we can, this is how we’re going to show you can get that improvement.

    It’s not magic, 

    Nicholas Gaudern: no 

    Allen Hall: power crews backing up with data, which I think is the key, right? Because you’re the, you do hear a lot of noise in this industry about magical products that’ll do all these things. Particularly aerodynamic ones. Yes. PowerCurves, the ones really bringing the data. 

    Nicholas Gaudern: Yeah. And we have, we have the track record now.

    We have like we do 17, 1800 turbines. Should be over 2000 very soon with our products on. Yeah. So we have a lot, we have a lot of data to draw on to know that we’re doing a good thing. 

    Allen Hall: Well, and speaking of that, because one of the questions that always pops up is, well, we have put these new VGs or trailing edges on, are they gonna stay on?

    How durable are they? 

    Nicholas Gaudern: Yeah. And that’s a, that’s a really important question to ask was it doesn’t matter how fancy aerodynamic product is, if it falls off the blade. 

    Allen Hall: Right. 

    Nicholas Gaudern: So, you know, we’ve spent a lot of, uh, time and effort looking at how we should be fixing these products on. [00:24:00] So we use a, uh, a wet adhesive.

    We specify a plexus adhesive to put our products in place. Really good adhesive. It’s a great adhesive and it means that they are not going anywhere. Basically. It’s a very, uh, forgiving adhesive. Uh, and it’s a very high spec. So we, we don’t use, uh, sided tape. We might have some of our products for some initial tack to help, you know, get the clear, the clear outta the line exactly.

    But in terms of the bond itself, that is with a, a proper structural adhesive. So one thing that we are really proud of is that we haven’t got any, uh, reported failures of our panels over all the installations we’ve made. And that’s a combination of materials, but also geometry, work, instructions, adhesive.

    It’s, it’s the full package. So it’s something that, um, yes, say we’re very proud of. And I think it’s, it’s a big part of what we do at PowerCurve, making sure the product is the right shape. Sure. But also making sure it stays on the blade. 

    Allen Hall: Well, you see it [00:25:00] from OEMs who have all kinds of aerodynamic treatments on there, and they’ll double set a tape to the blade, and then those parts are on the ground.

    Nicholas Gaudern: Yeah. And double-sided tape. You can get some really nice spec tape. Sure. 

    Allen Hall: You, 

    Nicholas Gaudern: yeah. But it’s not 



    Allen Hall: 20 year device. 

    Nicholas Gaudern: No. And the installation tolerance required on surface prep is really, really high. So it’s possible. It’s just harder. I think it’s riskier, 

    Allen Hall: it’s risky. 

    Nicholas Gaudern: So, you know, I think for us, the adhesive is, is the way to go.

    And, and it’s been proven out by the, by the track record. 

    Allen Hall: And some of the things we’ve seen over in Australia is when trailing ulcerations have come off, it’s been a safety concern. So now you got 

    Nicholas Gaudern: absolutely 

    Allen Hall: government officials involved in safety because parts are coming up. Turbine. 

    Nicholas Gaudern: Yeah. 

    Allen Hall: You 

    Nicholas Gaudern: can’t have these components flying, flying through the air.

    That’s, that’s not safe. 

    Allen Hall: That’s because PowerCurve has done the homework. 

    Nicholas Gaudern: Yes. 

    Allen Hall: And has the track record. That’s why you wanna choose PowerCurve. So how do people get a hold of PowerCurve? How do they get a hold of you, Nicholas, to start the process? 

    Nicholas Gaudern: So, um, you’re welcome to reach out to us in lots of different ways.

    We’re on LinkedIn. Uh, we have our website, [00:26:00] PowerCurve, dk, um, so yeah, LinkedIn websites. There’ll probably some links on this podcast as well to get in touch. But, um, yeah, whatever way works best for you. 

    Allen Hall: Yeah, it’s gonna be a busy season. So if you’re interested in doing anything with PowerCurve this year, you need to get on the website, get ahold of Nicholas.

    And get started, uh, because now’s the time to maximize your revenue. 

    Nicholas Gaudern: Thanks a lot and great to talk to you, 

    Allen Hall: Nicholas. Thanks so much for being back on the podcast.

    Matthew Stead: [00:00:00] The Uptime Wind Energy Podcast brought to you by Strike Tape, protecting thousands of wind turbines from lightning damage worldwide. Visit strike tape.com And now your hosts.

    Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host Allen Hall, and I’m here with Matthew Stead and Rosemary Barnes who are in Australia. Before we get too far into this episode, I would like to mention that the UK US relationship has been very tense recently, as you have seen in the, in the news articles and on television.

    But there was one good news piece that just happened, which is the band Oasis just got inducted into the Rock and Roll Hall of Fame. So that is trying to mend those relationships, bring the UK and US back together. In at least a musical sense. So I know Rosemary was watching that closely as the votes were counted.

    But, [00:01:00] uh, everybody in the UK is super thrilled about it as they should be. And all us Oasis fans can’t wait for the induction ceremony. In fact, we’re planning to go to Cleveland. They’ll go watch it if we can. We shall see now onto more important information this week. Vineyard, wind and GE are not getting along.

    And if you have been paying attention for the last two years, you would’ve noticed that there’s been a couple of tense moments. Well, uh, that wind project is a little bit up in the air because vineyard wind has filed suit against GE renewables to stop the turbine maker from walking away after GE sent a termination notice.

    Over a $300 million ish, uh, disagreement in unpaid bills. At the center of this dispute are defective blades, of course, that, uh, broke off in 2024 and caused a number of problems, uh, for GE and vineyard Wind is particularly a delay in the [00:02:00] project and ge having to fix pull blades off of turbines that were already installed and I think they ended up sending those back to France.

    Reading the lawsuit, it seems like GE did not repair those blades. They replaced those blades because, uh, they may not have been able to repair them or maybe is the amount of time it’s gonna take to repair them. You can repair almost anything made out of. Composite. Uh, but this is a big problem because, uh, if GE does walk away and they’re talking about walking away from this project at the end of April, vineyard, wind believes that the turbines are not ready to be operated, and they don’t have a way to operate those turbines.

    They don’t have the knowledge or the people because the people belong to GE that need to make some of these turbines operate. Even there’s even some question about if all the turbines are operating at the required [00:03:00]handover requirements. This is unique because I don’t think I’ve ever seen a wind turbine manufacturer leave before a wind site is finished.

    It must have happened before, but. It does put both sides in quite a pinch. Right. 

    Rosemary Barnes: Can I just jump, jump back to, to something that you said, um, that you can repair almost anything when it comes to composites? I would say that that doesn’t necessarily apply if your design was insufficient in the first place.

    And I mean the design for manufacturing in this case, I think that the, like computer model design worked fine, but obviously it was not as easy to manufacture or as possible to manufacture. With the correct quality as what they expected. It can’t have been so simple to just, just repair. That’s, um, that’s what I want to say.

    Like it, it’s obvious to me that if it was possible to repair, that would’ve been much easier than what they’ve ended up with, which I think is pretty foreseeable. Or most [00:04:00] engineers would probably have foreseen that if you, you know, put blades out there that, um, don’t meet your. Standard, um, quality control acceptance criteria that, you know, the consequence of that would be that it would be more likely to fail.

    So yeah, I think you can repair nearly anything on a standard blade that is possible to make correctly. But if you’ve got big quality problems, then it’s not, it’s, it’s not easy and it’s possibly not possible to, you know, just get, um, just get onto that in repair. 

    Matthew Stead: I, I think you’re both right. Because it all comes down to economics.

    So I think Alan’s statement, you know, things can be repaired. It just comes back to economics, doesn’t it? 

    Rosemary Barnes: U usually, yes. And like for your average, like if you’ve got a wind farm and you’ve got a blade with a big, a big repair, or you know, like a big defect right on the main laminate, that’s gonna require, you know, like a huge repair, taking the blade down and keeping it down for, you know, like three months while you rebuild like 20 meters [00:05:00] of laminate.

    Yes, that would be technically possible, but you wouldn’t because it would be so expensive. So us usually, like in 99% of cases, that would be it. That it’s not actually impossible to repair. It’s just very hard. But, you know, in these really huge blades and, you know, um, bearing in mind that I don’t, I don’t know the specific quality problems that they face, but, you know, just from my knowledge of composites, you can say what the challenging areas would be, but you know, a really big blade is gonna have a really thick laminate and, um, composites don’t like to have really thick laminates.

    When they cure, it’s usually an, an exothermic reaction, puts off heat, you know, like the temperature is changing and um, it works fine for thin laminates, but when it’s really thick you can get hot spots and cold spots and maybe it’s hard to get the resin to go all the way through evenly. But you know, imagine if you’ve got a really thick laminate and there’s a chunk of it that just didn’t get any resin in it.

    How are you gonna repair that? Like, I wouldn’t say impossible. I’m sure if the fate of the human race depended on it, then you would, you would make it work. But it’s [00:06:00] certainly very close to impossible. 

    Matthew Stead: Economically, it does not make sense. 

    Rosemary Barnes: You would probably have to make a few inventions. Along the way to be able to make it work as well.

    I think, 

    Allen Hall: I think I should read part of, and I don’t like reading these lawsuits, but this is informative in a sense that it provides some relative background as to what Vineyard Wind is thinking in some of the contract details that are involved here. So in June 4th, 2021, this is directly from the lawsuit, uh, vineyard Wind entered into A TSA with GE renewables in which.

    GE Renewables agreed to design, manufacture supply, install commission, and test the wind turbine generators for the vineyard wind project at a contract price of more than $1.3 billion. There you go. On the same day as an integral part of the commercial agreement, the parties entered into an SMA, uh, by which GE renewables agreed to maintain and service that wind turbine [00:07:00]generators for the first five years.

    Of operations of the project and guarantee that all wind turbine generators will operate at a 97% of production availability. Uh, this guarantee is central, is a central component of the commercial viability of the Vineyard Wind Project. So I would say so, right. Uh, at present, all of the wind turbine generators on the project have been installed.

    However, the wind turbine generators are not yet fully operational and are. Able to reduce power at only levels well below those intended under the contracts fundamental to the project’s commitment to Massachusetts to achieve full commercial operation. The project requires repair, commissioning, and maintenance of GE renewables, 62 proprietary wind turbine generators, and their component parts work that only GE renewables knows how to perform.

    So it sounds like Vineyard Wind has a five-year contract that GE ISS gonna operate these [00:08:00] turbines, and if they leave in a couple of weeks, vineyard wind really doesn’t have a backup plan. They may have. Were planning on a plan five years down the road where they could operate ’em, but to operate those turbines immediately when they haven’t, at least as.

    Indicated here may not be fully commissioned to providing the right amount of availability. That’s a huge problem for Vineyard. Huge. 

    Rosemary Barnes: It’s interesting to me that they’ve decided to withhold some money that I think everyone agrees that they owe that money to ge. But then there’s a dispute because Vineyard when says that GE owes them money for some other stuff That sounds like GE disputes.

    Um, it’s like if you have a problem. With your landlord, they always tell you, don’t, don’t withhold rent, because then they can, you know, that’s, that’s their out of the contract. Right? So it seems weird, like it’s a relatively small amount compared to what vineyard wind is risking. So. It seems to me like, are they, is this a mistake from them?

    Are they giving ge an out from this contract that’s gonna be [00:09:00] really hard for them to meet? It might be that GE knows what it would cost to entirely fix the wind farm and have it producing the way that it should. But, you know, let’s say in a worst case scenario, that means remaking every single blade in the um, in the wind farm.

    At the, at the French factory, you know, like that could be your, your worst case scenario. GE knows that that’s gonna cost more than what they’re ever gonna pay over the five years of, um, you know, the, uh, of missing the availability guarantee. So then it is worth, for them, the cost effective thing to do is to just walk away and they’re kind of, the amount that they’ll have to pay is limited.

    If I’m thinking fairness, it’s so unfair that vineyard wind would be stuck with this wind farm that they can’t really get to do anything. But if I think about how I see these disputes work out in the smaller versions of them that I’ve seen, it seems like vineyard wind actually probably is the one more likely to come out with a bad outcome from the way that they’re [00:10:00] choosing to play this right.

    Uh, because they, they risk not being able to operate at all. And they have potentially, like, I’m not a lawyer, I don’t, I don’t know about, you know, how likely it is that the 300 million, that their withholding will be enough for GE to walk away with without having to pay anything for, um, you know, not operating, uh, correctly over the next five years.

    But, um, you know, it just seems like it’s not so much money compared to the billions that are at stake. To risk that they will be left unable to operate the wind farm at all. You know, it’s just, uh, I don’t know. It seems risky. 

    Allen Hall: Let’s start with the kickoff of what happened and what vineyard wind is alleging happened from these, their perspective on it.

    It does provide some insight into all the things we talked about on the podcast for the last two years. We, we saw bits and pieces of it. According to vineyard wind, uh, GE Renewable [00:11:00] claims that it is owed quote amounts due unquote for milestone payments is, is contrary in in language to the TSA, so the turbine supply agreement put simply vineyard wind owes nothing to GE renewables because the TSA turbine supply agreement allows vineyard wind to withhold amounts.

    The project engineer determines that GE Renewable owes vineyard wind from milestone payments otherwise due under the contract. So what they’re saying is GE owes is a bunch of money. Yes, we do owe GE renewables money, but it’s in Vineyard Wind’s favor. So why would they send GE money? Um, those set off amounts are substantial because GE renewables caused catastrophic injury to vineyard wind by installing 68 defective blades on 24.

    Wind turbine generators resulting in two years of delay and over a billion dollars of damages. In July, 2024, one of the GE renewable offshore blades collapsed and fell into the waters off Nantucket resuscitating a massive environmental cleanup and requiring a six month [00:12:00] construction hiatus during which GE Renewable performed a root cause analysis, concluding that 68 of the 72 GE renewable.

    Blades installed at the project, nearly all manufactured by GE Renewable in Gaspay Canada, and they say nearly all, not all, nearly all were also defected because they were inadequately bonded together, the original blades were so poorly made that they were beyond repair. Indeed, the federal government required GE renewable to remove all the blades and to replace all gas bay blades with others manufactured at a different facility in Sherbrook, France.

    So that’s really the kickoff to all of this disagreement was the quality issues from Gas Bay. Uh, vineyard Wind goes on to say that GE Renewables and, and their CEO, Scott Straza, basically admitted to, uh, a, a serious, um. Overlook or quality issue? Quality escape, something of the [00:13:00] sort, uh, in some of the statements, which I, I remember him talking about 

    Rosemary Barnes: allegedly, in your opinion.

    Allen Hall: Well, and Scott Streek did say it. In fact, here’s, here’s what Scott Streek did say. Streek, uh, acknowledged that the blade failure and said, quote, we have identified a material deviation or a manufacturing deviation. In one of our factories that through the inspection or quality assurance process we should have identified.

    Because of that, we’re going to use our existing data and reinspect all of the blades that we have made for offshore wind and for context in this factory in Gus Bay, Canada, where the material deviation existed. That’s a quote. What happens now, 

    Rosemary Barnes: obviously I’ve never worked on anything that’s, this is the biggest example of, um, a, you know, a blade quality problem, a serial issue probably that’s ever happened in the wind industry.

    I’ve never worked on something this big, but I have worked on probably half a dozen small, small versions that are quite similar. Um. To this, but just on a, you know, a much, much smaller scale. And I will say that it never [00:14:00] feels fair what the owner of the wind farm, like, what the outcome is, never feels fair to the owner of the wind farm.

    Like when you’ve got a serial defect in, um, in play it like, and everyone suffers. It costs, it’s gonna cost the, um, you know, the manufacturer a lot of money. But I think that proportionally it is. Affects the owners more in nearly every case. It’s just there are some contractual things that you don’t end up with outcomes that feel, feel fair to anybody that, um, you know, would take a casual look at it.

    So I don’t think that an outcome that feels fair is probably likely for, for vineyard wind. Um, and I guess it all just comes down to whether or not GE agree that they owe that 800 million or whatever the figure is. Um, or if a court finds that they owe it. Because surely the contract doesn’t say that Vineyard wins engineer at any time can just, or project manager can at any time decide [00:15:00] that, um, GE owes the money and so they don’t have to pay.

    That obviously wouldn’t be a very, um, nice contract for GE to sign. So there’s gotta be some more nuance to it other than. That our project manager says, you owe us money so we’re not paying. And then, you know, you have to continue. Like, I, it’s probably impossible for us to, without, um, you know, having access to all of, all of the documents and the legal degree to understand it.

    Probably, probably hard for us to Yeah. Come up with a, a reasonable conclusion. 

    Allen Hall: It does make you think, usually the progression is dispute. Whatever contractually is obligated in the beginning happens. And so if there’s someone who decides what pot of money goes where, that, that’s usually the first step.

    Second step is usually arbitration in the us. I’d be surprised if they haven’t gone through at least an attempt at arbitration. And then once arbitration breaks down, then you go into the courts, which is clearly where they’re at now you’re, you’re at the highest level that you can be in terms of legal proceedings to try to sort this matter out.

    And I’m sure both sides. Do not want to be in front of a [00:16:00] courtroom if they can avoid it. So there’s a much more to come about this. I, I think the other operators, uh, GEs this is, is this GEs only? Yeah. This is GEs only wind farm offshore in the us So this is it. But I would imagine that the other, uh, operators in offshore wind in the US or.

    Being very careful word through contracts and how this is proceeding. 

    Rosemary Barnes: That’s something else I think about this case is that it’s going to be like the GE are the ones who have more at stake in terms of reputational harm. I would’ve thought then. Um, so. Yeah, that’s obviously a consideration that they’ve, they’ve gotta have, it isn’t, regardless of where the facts are, it’s not a good look.

    Right. Um, to be seen, to be walking away from a wind farm. And it probably would make other people considering big expensive GE wind farms to be like, oh, you know, are we actually gonna get across the line with this? Or is there a risk that they just, you know, throw a tantrum towards the end and threaten to walk away and we have to renegotiate [00:17:00] everything.

    So, um, I guess that there’s a, yeah, there’s always just the perception. Is as important in a lot of ways to what the actual facts are. 

    Matthew Stead: The thing I find is, um, I mean this is largely a legal thing, isn’t it? You know, we, we’ve agreed that it’s, with the lawyers, it’s a largely a legal thing. The, the sort of topic that I’m interested in is, um, like the example of you buy a car, you know, you buy a Toyota, um, you expect to be able to maintain it.

    You expect to be able to run it and get a serviced by a Toyota, you don’t expect in the first year to take your Toyota to Ford and get them to fix it in the first year. The bigger issue is the turbine supplier agreement does not actually allow the turbine to be operated without the OEM, so no one knows.

    No one knows how to run it. So for me, it’s a massive industry challenge, access of data, access of how to run a turbine. If the OEM is no longer there, so I think hopefully [00:18:00] this can have rama bigger ramifications for the industry that operators and owners can actually run the assets they own. 

    Rosemary Barnes: Well, there are companies that will come in and pull out your control system of your, you know, your turbine.

    If it, you know, if you, um, if you don’t wanna work with them anymore or if the company went bankrupt, then there are companies that will rip it out and put a new one in. It’s not, not saying that that’s like an easy, cost effective thing to do and probably not gonna get the same, um, performance as, as you originally did.

    But that’s what happens if you are, um, you know, your turbine manufacturer goes bankrupt and they just don’t exist to support anymore. Sometimes people have to resort to literally pulling out the whole control system and starting again. Not easy. When it’s something as big and new as this one obviously 

    Matthew Stead: isn’t the better answer that when you buy something, you actually buy the information to actually run it.

    Rosemary Barnes: I don’t fully agree [00:19:00] though, because. It’s like, um, o often what you say, oh, you know, like this would be good. Like the one common thing is people say, oh, you know, like it’s planned obsolescence. People, engineers plan design things to fail so that you’ll need to replace them. And I think that that does, that does happen again in like consumer, consumer products.

    Like, um, yeah, like your, your battery isn’t really designed to last for 10 years in your, your phone the same way that it is in an electric car. Um, more than 10 years in the case of an electric car. Um. But it’s not. It’s not what happens in industrial scale equipment. You are mostly worried about getting the price point right.

    And if you want something to last longer, if you want something that anybody can come in and fix it easily, it costs more to engineer like that and usually like a a lot more. So it’s not just people like evil engineers or evil. Um. Evil management at these, at these companies. 

    Allen Hall: I already get to evil engineers.

    Rosemary Barnes: No, people think it is. People think it’s evil. Engineers like purposely designing bad products to [00:20:00] um, make money, which I actually do think that they do with consumer products. Some of the time. Um, but when it comes to like industrial equipment, I, I don’t think that that’s the main, the main thing that planned obsolescence is not, is not a major factor here.

    It’s about trying to get the price point competitive to make sales. And if you want to get better engineering, you, you will, you will pay for it. 

    Matthew Stead: I got a call with someone today that, which is on this topic. So, you know, we, we are a sensor company and, um, we pro we provide results, okay? So if we actually provided the raw data that we measure, it actually allows people, other people to reverse engineer our products.

    So we don’t generally provide the raw data, so we provide the end outcome. Because it means that people can’t copy what we do. It means we can actually charge a lower price. So actually there’s a lot of logic to, you know, having, you know, [00:21:00] all these ways of engineering a product to, you know, give a better outcome to the end customer.

    Allen Hall: I know Rosie doesn’t like Elon Musk, but this one of the things that Elon Musk did with Tesla at least, I don’t know about the other companies that he runs, but with Tesla, they went off and. Made patents, right? So they applied for a bunch of patents and received them and then just made them open use. And the reason they did that was so somebody couldn’t jump the patent line, create a patent about some car related electric thing, and prohibit Tesla from doing.

    And so Tesla has always had the need to create patents that cost them, I’m sure, a, a pretty penny, just so they can avoid. Patent conflicts and lawsuits going forward. And it’s sort of the same thing, right? That the evil engineer bit, that’s the evil engineer bit I, that I don’t like is that when you get these crazy patent things happening out there that are just there to collect money and not do any of the work, 

    Rosemary Barnes: and some of the patents are.

    Absolutely crazy. Like when you do a patent search and it’s like you’re [00:22:00] reading the language and like it sounds like they’ve just patented the concept of a wheel, you know? And then you’ve gotta try and figure out like what’s actually going on. Yeah. In 

    Matthew Stead: our world, someone has a patent around the Doppler shift.

    Allen Hall: How can you have a patent on Doppler shift? That’s crazy. 

    Matthew Stead: It’s fundamental physical. You know, there’s a shift in frequency of a sound, um, 

    Allen Hall: based on speed 

    Matthew Stead: and yes, sound comes from a blade and there’s a doppler shift. 

    Allen Hall: That’s real. I, I, I guess, uh, see, that’s, that’s, that’s the craziness of that. See, you should have thought about.

    The idiots that were gonna do that and then write a patent about Doppler shift. 

    Rosemary Barnes: It’s really annoying because it’s like, you know that it’s not gonna be, I mean, a lot of them you are like 99% sure it’s not gonna be possible for them to defend that if it gets challenged. But it’s like, to what extent do we trust that, you know?

    Um, so you still usually end up steering around it anyway, but it, it really gets in the way of elegant engineering solutions. All these. Bizaro patents that are out there like clogging up [00:23:00] the design landscape. 

    Allen Hall: That happened recently. Right? Rosa? You had and I were talking about a particular patent. I thought had it existed and it did at one point exist and I.

    Rosie said, I don’t, I don’t see it anymore. So I did some search on it. Yeah, it got pulled off. Uh, the list of valid patents. It was a lightning related thing. 

    Rosemary Barnes: And you were complaining that it was so obvious that they should never have been able to patent it, but yeah, and somebody obviously said, said something at some.

    I don’t think patents are not the best way to protect an idea anyway. Right? Like nobody, if you, if you’ve got a new technology idea and you’re relying on a patent to protect other people from copying it, it’s not the best idea. I do work with a lot of small inventors who are like, oh, I’ve got a patent application, and they think it means something, that it doesn’t.

    They think, oh, you know, patent was approved. That means it works. It means it’s a good idea. It doesn’t mean any of those things for like small, outside of big companies. I, I think it’s super rare that you would get more. You would get a positive return [00:24:00] on. On filing and maintaining a patent in all the countries that, um, are relevant 

    Allen Hall: as wind energy professionals, staying informed is crucial, and let’s face it difficult.

    That’s why the Uptime podcast recommends PES Wind Magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future. Whether you’re an industry veteran or new to wind, PES Wind has the high quality content you need. Don’t miss out.

Rasmus abo, uh, says the company is about. One year into a turnaround plan, uh, that’s set to [00:25:00] run through beginning of 2028, and that the medicine is starting to work.

    Uh, one major strategic change. Ted will enter partnerships on new projects far earlier, and so it will never again, uh, be forced into damaging late stage divestments The company maintained its full year EBITDA and, uh, guidance of, of, of. 24 to 27 billion Danish kroner. That’s a good bit of money. And the sale of a 50% stake in the horn, C3 to Apollo Global Management for a billion dollars is already under.

    Well, at least in progress, but there’s a lot more behind the scenes here. Sted had an basically an investor meeting and a shareholder meeting, and, uh, they have three new board members. They let go of, if I remember correctly, three board members that were [00:26:00] employees that they just, uh, had reductions in forces that happen to affect board members, which is very odd.

    Very, very odd in my. Humble opinion, having watched number of boards for a long time, usually don’t remove board members in that fashion, but there does seem to be a, a, a more emphasis on the board to help, uh, the CEO of stead get through some of these tumultuous times and maybe a little bit of concern about the, the, the way the board was constructed to get or sit back into profitability sooner rather than later.

    This is a big deal up in Denmark. Of course, stead is the power company for Denmark. This has implications worldwide, though, uh, what stead does everybody else follows. And the one thing that, uh, that was sort of in dispute before the shareholder meeting was EOR at one point, was. At least contemplating a board seat.

    And then right [00:27:00] before the meeting they backed off and said, no, it’s fine. We don’t want a board seat. Maybe they had some sense of what the changes were gonna be made to the board, so they felt better about it. But orsa is not out of the rough seas at the moment. There’s a couple more years of, of growing pains and learning some lessons that they wish they didn’t have to learn.

    I guess that’s the way I would look at it. What implications does this have on the greater offshore wind community? Is stead taking basically a step back and, and trying to focus. Herding offshore wind, or is it just other, another companies are gonna step into that, that space that Sted may have previously occupied?

    Matthew Stead: I think what you’re talking about, um, Alan, is, is all logical. I mean, you know, you can’t have everything. So, um, as in you can’t, you know, getting late to a project and expect it to go well, um, spreading risk is a good thing, you know, so the whole, you know, [00:28:00] doing it fast. Doing it cheap and doing it well. Um, you, you, you can’t have all of those things at once.

    So actually what they’re talking about, I think is entirely logical. Um, so yeah, I think if they can lead the way that way and, and you know, I’ve come from, um, some other industries like construction and they, they spread the risk across multiple. Organizations that know what they’re doing. So the idea of joint ventures where you get the best of both worlds makes complete sense to me.

    Allen Hall: Do they start making different decisions on projects based upon their financial stake at the moment? A And more importantly, when they start looking for offshore wind projects, are they likely to hook up with Vestas? Because I, I think that’s where this is all going. 

    Matthew Stead: Pick a horse. 

    Allen Hall: Yeah, they’re gonna pick a horse.

    I, I mean, that’s the best, best way to think about it. They’re gonna pick a horse and gonna stick with them. Instead of having, uh, a lot of options and playing one against the other, I could see alignment happening, uh, versus being the [00:29:00] one offshore, of course. And or instead being a big player. There is, is that the combo that’s gonna push the industry forward?

    Rosemary Barnes: Yeah, maybe. I mean, I think it’s more similar to what Chinese manufacturers are doing, a lot more vertical integration. You can, um, yeah, save, save a lot of money by doing that. It is. Uh, you know, not always ideal from other points of view. And it might be nice to have a, you know, a thriving technology ecosystem of, you know, different manufacturers competing with each other and, you know, making better products.

    So, um, yeah, I don’t know, uh, have sit on the fence on this one for what’s good. I do feel really bad for osted though, like in terms of the, the. Shocks that they’ve had over the last couple of years. I, I don’t think most people would’ve foreseen that it would be so risky to try and expand into the US like everybody.

    A few years ago, everybody thought that that was the next big profitable frontier in offshore wind. And [00:30:00] I don’t think that many people would’ve foreseen things going the way that they did. 

    Allen Hall: Is it the result of large industrial projects take time and that in that timeframe, five, 10 years, that the world changes so much?

    You can’t. Accurately predict what the outcome will be and or it just got caught up in it. 

    Rosemary Barnes: Yeah, I think that’s actually one of the themes you guys have read, um, how big things get Done Right by Ben. Um, that’s one of the things that he mentions that the quicker that you can do the execution phase of your project, like spend plenty of time planning it, but when you’re actually committed, work super fast because the longer that you’re working, the more your chance of a, a black swan.

    Um, a Black Swan event be, you know, a government that turns out to, you know, want to, you know, tear up contracts and you know, do all these other unprecedented stuff. You know, if you’ve got projects that take 10 or more years to build, then there’s just like a lot more risk of something like that happening.

    And I think that, um, you know, like in some ways that’s just one of the inherent weaknesses of [00:31:00] wind energy in general, but offshore wind especially is that it does actually take a long time to get through all of the things that you need to do to. Um, to complete a project. And so it’s just, yeah, a lot more chance for, you know, the government will change two or three times probably in, um, you know, during a project.

    How many wars can start, how many, you know, pandemics. Can there be you? Like, the longer that you’re going, you might think none of those things could be predicted and that can’t, but you can predict that those sorts of big things happen. And the longer that you, um, are exposed and the more of them that you’re probably gonna face.

    And I think that, yeah, like something like a solar farm is much quicker to roll out. Um, battery projects are much quicker to roll out. So it’s just like that, those are benefits of those technologies compared to wind. You just have to kind of accept that that’s one of the weaknesses of this, this industry that we’re in.

    Allen Hall: Is it a benefit to have solar because it can deploy very quickly, or, or is it just [00:32:00] smarter to have. More wind turbines of smaller megawatt outputs because you can manufacture ’em at scale quicker, and so the economies of scale don’t really matter so much. This is an argument we’ve been making for months now, that when you start selecting a single turbine, which doesn’t have any history, and it’s a big one, and it takes a long time to produce, you are really setting up yourself to fall into that window where something can go wrong.

    Versus just stamping out two or three megawatt turbines and going like crazy. It just seems so much less risky. 

    Rosemary Barnes: I think that I definitely agree with you for onshore and then for offshore. Probably also, like I don’t think it’s necessarily go for a smaller turbine. It’s just don’t go for the brand new one.

    Like that’s why I don’t understand how many people are like so obsessed with this, you know, small, small amount of improvement that they get from the very biggest. Turbine, but I don’t think that they realize the amount of technical risk. And I think that it gets, it’s getting [00:33:00] more and more like the, um, technology increment is getting more and more the bigger that we go.

    It’s not that like, oh, we’re learning how to do this, this, well, it’s, it’s the opposite that, you know, like every, um, increment up in size as an exponentially more like larger number of problems, technical problems that have to be solved. And, um, I think that, yeah, that’s. That’s something people don’t factor in.

    Allen Hall: Is it the gold rush problem where the miners were trying to hit that pocket of gold and spending all their time trying to find this gold, find this gold. In the meantime, a lot of them obviously broke, and the people that made money in the gold rush or the stores that sold the pickaxes, if you, you making a pickaxes, you have a customer page, you can just sell those things in.

    Levi’s, be the other one, right? So they’re selling genes of pickaxes to the miners. Guess who won in that battle, right? Levi’s. 

    Rosemary Barnes: But what’s the analogy with win two of the pickax manufacturers, 

    Allen Hall: the people that make the two megawatt machines? In my opinion, that’s gonna be who the pickaxes are because you don’t have to think about it.

    If [00:34:00] you can talk to operators of the United States today and you say, what turbine would you like to buy over again? And they will almost all tell you, GE one point fives. Almost all of them. And you go, yeah. Oh, okay. I understand it because it’s a machine. It’s pretty simple. But it does work. And it is, it is a true warhorse turbine.

    And some of the vested ones are the same. Simpson Siemens turbines are very similar, right? Uh, but in today’s world, when we’re talking about 15, 20 megawatt turbines, I just think, man, you gotta be careful doing that just because of the time it takes to develop it and produce it, and. Work at all the kinks?

    Uh, Rosemary, I think you’re right about that. 

    Rosemary Barnes: I think the issue is that, um, when you’re deciding whether to develop a project or not, it really depends a lot on what the spreadsheet tells you your return is going to be. And, um, you know, a bigger turbine with, uh, you know, like larger output over its lifetime, longer lifetime.

    Those are all gonna give you really good. Spreadsheet numbers, but what’s not in the spreadsheet [00:35:00] is, oh, you know, you’ve actually increased your risk of having to wait two years while they replace every single blade in this, um, in this wind farm. Oh, by the way, yeah, you’re gonna be dealing with, um, you know, twice as many repairs and your, um, downtime is not gonna be 2%, it’s gonna be 3.5% or, or something.

    You know, those, those sorts of things, I don’t think, uh, adequately captured in the, the spreadsheets whe say when you, whether you should or shouldn’t develop a new project. 

    Matthew Stead: So, so the evil engineering should be making decisions, not the evil lawyers. 

    Allen Hall: The financial people always make the decisions, right?

    The insurance companies make the decisions. 

    Rosemary Barnes: Don’t think there’s a lot of engineering into, um, input in the, the very first stages. But I also think that if you put in the reality, like most engineers, I think are a little bit pessimistic because our job is to see what problems exist at, you know, and then solve them ideally.

    Um, but at least part of it, like our brains are wired to look for problems, right? That’s, um, that’s a necessary part of the job, in my opinion. But if you were, you know, like pessimistic in your assumptions in the [00:36:00] spreadsheet, you would probably the majority of the time say, don’t make this project. The return is not very good.

    Allen Hall: Well, that would be a smart move, right? Yeah. 

    Rosemary Barnes: Yeah. So I don’t actually think you probably should have too many engineers in in involved. 

    Matthew Stead: Yeah. But what is the CEO incentivized by is the, yeah, so it, it comes back to, you know, what, what, what drives the project And it’s not just engineering.

    Happy Monday, everyone.

    While headlines this week captured courtrooms and bankruptcy filings and permitting backlogs, out on the open water and deep inside factory order books, the wind turbines kept getting built.

    Let us start off the coast of New York. Friday morning, April seventeenth, Ørsted installed the first wind turbine generator at Sunrise Wind — a 924-megawatt project, 84 turbines when complete. This is the same Sunrise Wind that was shut down just four months ago. The same Sunrise Wind that won a preliminary injunction in February. The same Sunrise Wind the Trump Administration chose not to appeal. And now the first turbine stands above the water. Cadeler’s wind turbine installation vessel Wind Scylla is doing the work. She just finished the same job at Revolution Wind. Ørsted says first power flows to New York later this year. Commercial operation the second half of 2027. Six hundred thousand homes on the grid.

    Now follow us across the Atlantic. In the Polish Baltic Sea, another Cadeler vessel just began her maiden campaign. Her name: Wind Mover. Delivered last November from Hanwha Ocean in Korea, ahead of schedule. This new M-class installation vessel now sits at the 1.2-gigawatt Baltic Power offshore wind farm, installing Vestas V236 turbines — 15 megawatts apiece. Wind Mover’s sister vessel, Wind Osprey, is moving to the United Kingdom to start work at East Anglia Three. Cadeler has doubled its fleet in twelve months. By mid-2027, twelve vessels — the largest offshore wind installation fleet in the industry.

    While turbines go up on the eastern side of the Atlantic, on the western side a different kind of wait is setting in. Bloomberg reported last week that the Pentagon is sitting on a backlog of at least 30 proposed American wind farms — 7.5 gigawatts of onshore capacity. Paperwork stalled. The issue is Section 10-32, the Defense Department’s review to ensure turbines do not interfere with military radar or aviation. Jason Grumet, head of the American Clean Power Association, calls it direct obstruction. His group sent a letter to the Pentagon earlier this month. The deadline for a response was April eighth. That deadline came and went. Seven point five gigawatts, waiting.

    Now turn to the United Kingdom, where the direction could not be more different. A new report commissioned by Renewable UK and written by consultants at Everoze says expanding Britain’s onshore wind supply chain between now and 2050 could add £56 billion in economic value. That is on top of another £98 billion already expected — a total of £154 billion. UK onshore capacity is set to grow from 16 gigawatts today to more than 50 gigawatts by 2050. Seventy percent of lifecycle spend already stays in the UK. The report points to blades, towers, nacelles, drivetrains, and electrical gear for substations as the highest-value opportunities.

    So let us step back. One turbine above the water off Long Island. A new vessel installing 15-megawatt machines in the Polish Baltic. Seven point five gigawatts of American onshore wind held up in Washington. And £56 billion staked on British onshore.

    The policy fights are loud. The legal fights are louder. But this past week, the turbines went up.

    That is the state of the wind industry for the 20th of April, 2026.
