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 podcast. Nicholas Gaudern: Thanks, Allen. Great to be back. Allen Hall: So there’s a lot going on at Power Curve, and I saw some news online about Power Curve in India. Nicholas Gaudern: Yes. Allen Hall: Which is a new development. Nicholas Gaudern: Yeah, so we’ve been working in India for, for some years now, and we have, uh, more than 100 turbines out there with our equipment on, primarily vortex generators so far. And what we’re seeing in India is some of the highest AEP gains we’ve ever recorded with our vortex generators And I think a lot of this is being driven by the fact that in certain parts of India, there’s some very unique, uh, environmental conditions, climatic conditions, and there’s parts of the year, like the dry season up in [00:01:00] the north of India, where you’re getting this very sticky dirt accumulating on the blades. And it’s really quite dramatic when you see the photographs, but that means that the blades are actually starting to, to stall, have flow separation on them. Allen Hall: I’ve seen pictures of that. Yeah. I was really shocked at the time, uh, ’cause I didn’t know it was just kind of a black, gooey- Yeah … kind of tar-like substance- Yeah, yeah on the blades, and, uh, it, it was only on there a limited time. As soon as the monsoons come through and the rains hit, it would wash, eventually wash it off. Yes. But while it’s there, you could see the airflow over the blade surfaces. You, you could definitely see separation happening really early on those blades. Dramatic. Nicholas Gaudern: Yeah, absolutely, and I think the, um… Like you say, it’s not all year. No. But it doesn’t have to be all year to have a huge impact on, on how many, you know, megawatt hours you’re getting out the other end. So there’s a few months of the year where this problem is particularly severe, maybe sort of December through to February, something like that. And what we’re finding is that when you see, uh, the power curves for these [00:02:00] turbines, some of them aren’t even hitting rated power. They’re not able to hit rated power because there’s so much flow separation on the blades. Allen Hall: Wow. Nicholas Gaudern: And that, I mean, just imagine that. You’ve got a two megawatt turbine, for example. Maybe it doesn’t cast- get past 1.5 megawatts for this, uh, time of the year. I mean, that’s crazy. Allen Hall: Does the turbine try to adjust itself when that happens? Because the pictures I s- have seen indicates, like, the turbine is pitching the blades to, ’cause it knows- It can- … Nicholas Gaudern: what the wind Allen Hall: speed is- I mean, yeah … and it knows what it should be putting out, and it’s not putting that out. Nicholas Gaudern: It’s very turbine specific, kind of controller logic specific, but what we see is even the turbines that try to do something, they’re very limited in how much pitch authority they have from the controller. They might be able to just do a little bit, a degree. Okay. Two degrees. You know, very, very small pitch adjustments. And when you have this kind of dirt on the leading edges, a degree of pitch ain’t gonna save you really. Um- N- Allen Hall: no. And I think that’s what we’re seeing. And it’s not gonna get that power back. No, no. Nicholas Gaudern: No. Allen Hall: But does it add extra load onto the blade structurally over [00:03:00] time when you do that? Nicholas Gaudern: In terms of the pitching, or- Allen Hall: Yeah, in terms of the pitching, where you’re trying to be more aggressive on the angle of attack to get the power out of the turbine. Potentially. And the winds are still pretty strong, you just, the blades are inefficient. Nicholas Gaudern: I think it’s one of those things where there’s, there’s so many interconnected items with the dirt and the controller and the structure. It’s actually pretty difficult, I think, to say with confidence how much life impact you would have from that. But what I would say is the more that you might end up trying to pitch, if that’s what’s going on on some machines, that obviously puts wear on the pitch bearings themselves. But yeah, I think at the moment ...

  • Storm Damages ENGIE Wind Farm, Mexico Plans 7 GW
    2026/07/06
    Allen covers a storm that damaged ENGIE’s South Dakota wind farm, Sumitomo exiting two Belgian offshore farms, Envision’s loss in Denmark, and Continental building its own wind farm.

And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Happy Monday everyone. Sometimes … Mother Nature reminds the wind industry who is really in charge. Late last month … hurricane-force winds ripped through Hyde County, South Dakota … tearing into the Triple H Wind Farm operated by French energy giant Engie. One hundred and thirty-one miles per hour … as strong as a Category Four hurricane. More than twenty of the site’s ninety-two turbines … damaged. The two-hundred-fifty-megawatt complex is out of service … and turbine supplier GE Vernova is on-site now … assessing the wreckage. No injuries … but the governor declared a state of emergency. The machines that harvest the wind … taken down by the wind itself. Now … while one wind farm goes dark in the American plains … ownership is reshuffling across the North Sea. Japan’s Sumitomo Corporation has exited two Belgian offshore wind farms … selling its stakes to joint venture partner Jera Nex BP. That is the partnership between oil major BP and Japan’s largest power generator Jera. Jera Nex BP now has full ownership of the two-hundred-nineteen-megawatt Northwester 2 … and has raised its stake in the one-hundred-sixty-five-megawatt Nobelwind to eighty percent. Both farms operate out of Ostend, Belgium … and have been generating power since 2017 and 2020. Sumitomo walks away … Jera Nex BP doubles down. Meanwhile … in Denmark … China’s Envision Group is seeing red for the first time in fifteen years. The company’s global innovation center in Silkeborg … a strategic research hub for wind turbine components and advanced manufacturing … posted a loss of just under one-point-three million Danish kroner. That is a swing of more than one hundred fifteen percent from last year’s profit. The culprit is not the technology … it is the currency. The U.S. dollar fell nearly twelve percent against the Danish krone in 2025 … and Envision’s books took the hit. Revenue also dropped eighteen percent … but management says the underlying operations remained stable. The machines still work … the math just changed. And speaking of money flowing into wind … a Turkish energy company just tapped an unusual source. Aksa Enerji … the largest publicly listed independent power producer in Turkiye … has secured one hundred twenty-four million dollars in financing backed by China’s export credit agency Sinosure. The money will fund a one-hundred-megawatt wind-plus-storage project in the southern province of Mersin. This is the first renewable energy project in Turkiye to receive a license as a storage-integrated facility. Aksa now operates power plants across seven countries … with more than three gigawatts of total capacity. Chinese capital … backing Turkish wind … with battery storage baked in from day one. Now … here is a story that might surprise you. Continental … the German tyre maker … yes … the tyre company … is building its own wind farm. Three Nordex turbines … each standing two hundred sixty-seven meters tall … right next to its tyre factory in Korbach, Germany. When they are online … those turbines and the factory’s existing solar panels will cover two-thirds of the plant’s electricity demand. Fifty-five gigawatt-hours a year … powering rubber mixing and extrusion lines … directly from the wind. Continental calls it a model for its production sites worldwide. Cheaper power … more predictable costs … and less exposure to volatile energy markets. The wind industry just gained a tyre company as a customer … and a competitor for electrons. And finally … south of the border. Mexico has eight gigawatts of wind power installed today … more than thirty-three hundred turbines across sixteen states. But the next chapter is already being written. The government plans to add nearly seven gigawatts of new wind capacity this term … part of a broader push for thirty-two gigawatts of new generation overall. More than two gigawatts of wind projects are pending allocation right now … and the industry estimates this next wave could mobilize four to five billion dollars in investment … building thirteen to fourteen new wind farms before the decade is out. The final decisions come in October. Here is what stands out this week. The wind industry is no longer just selling kilowatt-hours to utilities … it is selling energy ...

Allen Hall: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall, and I’m here with Matthew Stead and Yolanda Padron. Rosemary is at GWO training this week. And we have an announcement about Wind Energy O&M Australia 2027. Matthew, you wanna give all the details? Matthew Stead: Drum roll Um, very pleased to announce that WOMA 2027 will be at the East Pullman Hotel in Melbourne’s east, uh, not the other one, and, uh, 3rd to 5th of March. Um, the first two days will be two days of wind O&M, uh, conferences, [00:01:00] uh, and then the Friday will be a half-day, uh, training session. More information to come. Allen Hall: Well, she’s not here, so we can probably just announce it, that Rosemary will be giving a terrific four-hour-long seminar on blades and blade repair, so you sign up now. Matthew, where do you go if you wanna just check out what’s happening at WOMA Matthew Stead: 2027? Uh, well, actually, it’s woma2027.com. Allen Hall: Uh, over at GE Vernova and LM Wind Power, there’s been a whole bunch of turmoil over the last couple of years if you haven’t been paying attention. Well, GE Vernova just injected about a billion dollars into that company. So although LM recently has shown very little in terms of revenue, it definitely had needed some capital injection in, uh, at least according to the Danish press, the number of employees at the Danish site is about 20 to 30. So it’s really a fraction of what it once was. But [00:02:00] it does seem like GE is paying off all its existing debt and then giving it a little bit of a cash infusion to keep it rolling. The question really is, is what is GE Vernova gonna do with that business now? Are they planning on keeping it? Are they trying to get s- to get it back to health where they can service the other, uh, OEMs that they manufacture blades for? Or is there a larger action that will happen in the near future? What do we think? Matthew Stead: Yeah, I’m really confused by this one. I mean, a cash injection just so that you’re not bankrupt on paper is, um, that’s just playing with money as far as I’m concerned. Or I’m not sure if it’s a US term, but, you know, shuffling deckchairs on the Titanic. It doesn’t– Does it change anything? Allen Hall: Well, uh, th- they made no announcements about closing facilities. The LM blade facility in North Dakota still appears to be making blades. There’s the TPI factories, which are going through a transition r- right now, appear to be making GE [00:03:00] blades. I, I assume Gaspé up in Canada is still making blades, at least that’s the story. If GE’s gonna rely upon LM to make blades, they’re gonna need to keep them open. Is, is this more of just keeping the factories open with a skeleton engineering crew and possibly moving the blade design group into the States? Is that– Or India or, or somewhere? Yolanda Padron: And they’re still selling, right? They’re still selling blades. It seems like they’re still planning on manufacturing blades. Do we think that maybe- They’re just trying to avoid that whole TPI bankruptcy deal to not have to kind of scrap for parts? Allen Hall: Yeah, it’s a great question. I think TPI has been producing parts at high quantity, and some of the Things I’ve heard from the industry folk is that TPI is really busy in producing quality blades, and it’s like the bankruptcy transaction is not happening, which is great to hear because the [00:04:00]industry needs blades, and there’s a lot of repowering going on in the United States and a lot of activity in general, so they need blades. But does LM continue to be a part of that? Matthew Stead: Yeah, I mean, presumably the TPI, um, whole story only makes LM more important, you know, more important to have, uh, an additional manufacturer and, you know, providing, you know, options for the OEMs. Allen Hall: It does seem like, though, the GE offshore, GE Vernova offshore is not a thing. Although I’ve heard a couple of rumors that, yeah, GE Vernova is offering some products for offshore, it doesn’t seem like their heart is in it. I can see ...

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow Allen Hall: Dan, welcome back to the podcast. Dan Fesenmeyer: It’s great to be here. Great to see you again. Allen Hall: There is so much happening in your particular area. Your name pops up quite a bit within Weather Guard because, uh, we’re dealing with a lot of operators and- A number of times we’ll ask them, “Have you read your turbine supply agreement?” “No.” “Have you read your full service agreement?” “No.” “Well, maybe you should do that.” And then we say, “Have you talked to Dan? You should call Dan, ’cause he can help you understand what you have signed.” Mm-hmm. “Oh, that’s probably a good idea.” So now that you’re here, WindQuest Advisors, of course, obviously is your company. Mm-hmm. And you’re talking to a number of operators. The, the big hurdle at the minute, the nearest short-term hurdle, is repowering. There’s just a lot of [00:01:00] repowering efforts going on- Mm-hmm … trying to get turbines in, start a project. There’s a July 4th deadline and an end of the year deadline. There’s a couple deadlines after that. What are you seeing right now from operators i- in terms of repowering? What’s the effort happening? Dan Fesenmeyer: Well, there was a ton of effort to start physical work. That window’s obviously closing- Allen Hall: Yes … Dan Fesenmeyer: very quickly, but it’s still open. Uh, and then once you’re past that window, my understanding is if you get your repower completed by the end of ’27, you didn’t really need to have started physical work. But I think most folks, start physical work is kind of the insurance piece of it- Allen Hall: Sure … Dan Fesenmeyer: if things take longer. Uh, another thing that’s popped up is obviously FAA and other permitting. Allen Hall: On the permitting side, from the federal’s, uh, standpoint, is that stopped? Or, or are projects able to continue putting turbines in the ground, or what’s the status? Dan Fesenmeyer: My- From what I’ve seen, I think on the opening session here at [00:02:00] ACP, it was said, they said that there’s, like, 130 projects that are- Allen Hall: At least … Dan Fesenmeyer: caught. Yes. And I’m, I’m involved with some of them, and I have a fairly small shop, and there’s just no FAA variances or permits or- They’re not issuing- … mitigation studies. Everything seems to have stopped. Allen Hall: So they’re not even reviewing the documentation that’s been submitted by the operators at all? Dan Fesenmeyer: That’s what it seems, yes. Yeah. Allen Hall: Is that legal? Uh, uh, usually those federal requirements have a timeline which they’re able to review those permits and get them approved or disapproved them. You’re s- Right … I think what I’m hearing is, what you’re saying is they’re not even looking at them. Dan Fesenmeyer: That’s correct. That’s what I’ve heard and seen. Allen Hall: Okay. Dan Fesenmeyer: Yeah. Yeah. Allen Hall: So what is an operator to do then? How does this, how do they meet some of these deadlines if they can’t get the permit? Dan Fesenmeyer: Well, I mean, it stalled a lot of projects ’cause of the associated risk with it. Although I’ve seen some, uh, you know, some repower folks think, “Well, you know, I’m just repair- repowering like for like, or I’m not changing much.” [00:03:00] But if your, if your rotor’s changing or pad location’s changing, you need to update those permits. Allen Hall: So the, the groups and the operators that are repowering the existing turbines are putting basically the same turbine in the same hole. Dan Fesenmeyer: Well, Allen Hall: I- Would that be okay? Dan Fesenmeyer: I would say originally- The initial push on repower was kind of your larger rotors- Sure … new drivetrain, et cetera. Yes. The market seemed to shift more towards, “Hey, let’s do smaller upgrades, component exchanges.” Allen Hall: Okay. Dan Fesenmeyer: Getting more towards the minimal investment, so to speak. Allen Hall: The 80% investment portion. Dan Fesenmeyer: Yes. Allen Hall: Right. Dan Fesenmeyer: Yeah. And less about, you know, a big ...

  • Poland Powers First Offshore Wind, Vestas Expands in Japan
    2026/07/13
    Allen covers Poland connecting its first offshore wind farm, Ocean Winds reaching full power in the Mediterranean, Stiesdal’s floating wind cost breakthrough, Vestas expanding in Australia and Japan, a federal permitting freeze stalling 250 US projects, and India passing 50% clean power. Sign up now for Uptime Tech News, our weekly newsletter on all things wind technology. This episode is sponsored by Weather Guard Lightning Tech.

And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Happy Monday, everyone. A coal-dependent nation just plugged into offshore wind for the very first time. Poland’s power grid received electricity this past week from its first offshore wind farm in the Baltic Sea. It’s called Baltic Power, a joint venture between Poland’s Orlen and Canada’s Northland Power. It began sending electricity from its 76 turbines to shore — about a 1.4-gigawatt site, enough to power more than 1.5 million Polish homes. And this is more than just one wind farm. Poland is shifting its entire energy map. For decades, the center of electricity generation sat in the coal-rich south. Now it’s moving to northern Poland, to the coast. The country plans six gigawatts of offshore wind by 2030. Equinor and Ørsted are both set to build along that Polish shoreline, and that’s good news. A new 530-million-złoty substation — about $140 million — is part of a plan to build nearly 5,000 kilometers of high-voltage lines to carry the power to southern Poland. Coal still supplies more than half of Poland’s electricity, but that number is about to change. And now down to the south of France. Ocean Winds, the offshore wind company created by EDP Renewables and Engie, just reached full power at a floating wind farm in the Mediterranean Sea. It’s three 10-megawatt turbines sitting on semi-submersible floaters 16 kilometers off the coast. It’s a pilot project, but the lessons are real: 99% of the suppliers are European, 85% French, and it proves that floating offshore wind can work in deep Mediterranean waters. Now we’ll stay with floating wind for a moment. Danish company Stiesdal Offshore says it has cracked the cost code, and this is important. The company modeled what it would take to build a full-scale floating wind farm — one gigawatt from a single port in a single installation season, loading out one turbine per week. And the cost? Less than one million euros per megawatt. That is on par with the jacket foundations used for fixed-bottom turbines in deeper water. About 80% of the world’s oceans are roughly too deep for conventional foundations. And if those numbers hold — one million per megawatt — floating wind just got a whole lot more investable. Meanwhile, Danish Vestas is making moves on two continents. In Australia, the Danish giant bought a 272-megawatt project in Tasmania from Ark Energy. It’s called the St. Patrick’s Plains Wind Farm, and once built it would be the biggest wind project site in the state. Vestas now has more than 13 gigawatts of wind projects in its Australian pipeline. So the model is clear: buy early-stage projects, bring in investors and offtakers, then supply the turbines to build the farm. The turbine supplier is turning into a wind developer. And over in Japan, Vestas secured backing from the Japanese government to build a wind turbine assembly factory. Japan’s Ministry of Economy, Trade and Industry has committed support for the facility. Vestas already has about two gigawatts of turbines installed in Japan, including machines at the country’s largest operational offshore wind farm. A factory on Japanese soil puts Vestas closer to an offshore market that is just getting started. Now we turn back to the United States. In Minnesota, four wind energy projects are stuck in limbo. The Department of War has stopped completing national security reviews for proposed wind farms. Those reviews used to be routine. A new report says more than 250 wind projects are stalled nationwide because of it. In Minnesota alone, the four frozen projects represent over one gigawatt — that is more output than the state’s twin nuclear reactors at the Prairie Island Power Plant. So at stake is $1.6 billion in direct investment, about 5,600 jobs, and more than $168 million in economic impact. Nine clean energy groups have sued the War Department to break the logjam. And over in Ohio, the state senate passed a bill that could block many new wind farms and solar farms. The bill says power sources must be available at least 50% of the time, and wind and solar on their own rarely hit that number. The Ohio Chamber of Commerce opposes the bill, and so does the grid operator. But the bill has passed the Senate and now heads to the House. ...

Protecting thousands of wind turbines from lightning damage worldwide. Visit striketape.com. And now your hosts Allen Hall 2025: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Matthew Stead, Yolanda Padron, and Rosemary Barnes is back this week. Rosemary, you’ve been to a number of training courses over the last couple of weeks. The first off was GWO. What was your experience at GWO training? Rosemary1: It was the fourth or maybe even fifth time that I’ve done it. Um, I did it a few times in Denmark and then, uh, this is the second time doing it in Australia. also, this was my first time doing first aid in Australia. Last time they did GWO here, but my first aid was still valid from Europe, so I, I didn’t redo it. And it’s like so much about [00:01:00] snakes and spiders and jellyfish But a good, good rule of thumb, not 100% accurate, but good rule of thumb, if it is something from the ocean that stung you, then you put something warm on it, and if it’s something from the land that stung or bit you, then something cold on it, Allen Hall 2025: well, how often do you usually take GWO training? Rosemary1: You gotta do it every two years to be valid. I don’t do it every two years because, um, if you do it every two years, like within two years, then you can do the refresher course. So that’s three days instead of four However, um, because I don’t climb constantly, like often it will be six months or more in between climbs, I’ll just do it before I know that I’ve got a climb. all the other people except for one were technicians who, you know, have been working for a while. So they’re also doing the full course, not the refresher. So they get a little bit more practice than I do. But, um, it’s just not often enough. Y-you know, like every time I go it’s like I, I really feel the need to have the refresher, um, because I’m just not fully on top of it. ‘Cause it’s [00:02:00] not just that you need to know what to do. You need to be able to… Like if you need to use it, you’re gonna be freaking out, you know? This is the worst thing that’s probably ever happened in your life, and now you’ve gotta remember all your training. It’s like you want it to be actually second nature to some extent. So yeah, first day is manual handling, which is v- you know, very– That one’s very easy and I would be happy to never do that again. Like I will always remember that. Um, then you got fire, um, fire safety awareness, and that one’s just fun ’cause you just get to, um, light fires and put stuff out then first aid, which I definitely always want a refresher on. The CPR dummies at this place, they had lights, um, and it lit up green if you were doing it right, and I haven’t used a dummy that was so advanced before, so that was quite good. I realized I wasn’t pressing hard enough. and then yeah, last two days is working at heights training, which is the most intense ’cause you got your harness on all day and, um, you know, climbing up and down and rescuing people. this was Rite Training in Goulburn, and, um, the [00:03:00] instructor’s name was Claire. highly recommend doing that one. Allen Hall 2025: Is that a general requirement in Australia that you have GWO before you can climb? Rosemary1: Like, yeah, they will sometimes, um, let you climb if you are babysat by people. I would not recommend other engineers, like if you’ve never climbed a wind turbine before, like I would really not recommend that you just go up with a team and haven’t done the training because you do need to be able to use a ladder safely and, um, you can, y- you can easily, like even inside the nacelle, you could easily hurt yourself really badly if you’re used to working in an office, uh, you’re upping your danger level by, you know, like many, many, many times by going up a turbine and it’s just something that you gotta take seriously. Allen Hall 2025: How busy are the courses in Australia? Are a lot of technicians trying to get in and get trained? Rosemary1: No, it’s people that have a job...

  • Malloy Wind and NSK on Main Bearing Failures
    2026/07/16
    Cory Mittleider of Malloy Wind and Loren Walton of NSK on main bearing failures, why the industry is pulling DLC coatings, and the material changes replacing them. Sign up now for Uptime Tech News, our weekly newsletter on all things wind technology. This episode is sponsored by Weather Guard Lightning Tech. Learn more about Weather Guard’s StrikeTape Wind Turbine LPS retrofit. Follow the show on YouTube, Linkedin and visit Weather Guard on the web. And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Allen Hall: Cory and Loren, welcome back to the podcast. Cory Mittleider: Thanks for having us. Allen Hall: So we’ve got two bearing experts in one location, and this is the point where we start asking all of our bearing questions. Cory, you’re with Malloy Wind, and we’ve had you on the podcast two or three different times. Loren’s with NSK — we’ve had Loren on at least once before. Loren Walton: Once, yes. Allen Hall: Yeah, and that was good. Loren Walton: I appreciate that. It was fun. Allen Hall: There are a lot of bearing issues happening in the States at the moment, but also globally. Whatever happens in the States, you can pretty much find in Australia, Canada, Singapore, Mexico, South America, Brazil — everywhere. We’re hearing a lot about main bearings, and there’s a variety of things that I think you two know from being on the inside that we on the outside haven’t heard yet. I want to get some of those stories out and understand what’s going on, because operators are trying to keep their assets running, and bearings are a big issue. Let’s talk main bearings. What are you seeing in the field right now? What kinds of problems are happening? Cory Mittleider: It seems like operators are coming to us and asking us to supply bearings that no longer have DLC. That’s a bit of a phenomenon lately. For a little over a decade we spent our time supplying bearings with DLC on the rollers to address problems found fifteen years ago. Allen Hall: DLC is diamond-like coating. Cory Mittleider: Correct. Allen Hall: Which is a really hard specialty coating applied to the bearing surfaces to provide hardness and durability — or it’s supposed to provide durability. Cory Mittleider: That’s a good point. It’s a coating that’s one to two microns thick — one to two thousandths of a millimeter — and a very hard material. The big feature was that it’s a dissimilar material to the steel. So when we break through the mixed and boundary lubrication regimes and those asperities touch each other, that dissimilar material prevents the welding and tearing that leads to the peeling damage we saw fifteen years ago. That peeling damage eventually turned into spalling, cracking, and other failures. So it made a lot of sense at the time to turn to something like this to mitigate the peeling. Allen Hall: So the peeling damage was one of those issues where you basically had some sliding happening. In my electrical world, and from looking at these on the ground, you see things moving relative to one another instead of rolling relative to one another. Loren Walton: It’s more of a welding and shearing of the contacts. I used a finger analogy last time: think of your asperities as fingers — one set is the roller, one set is the outer raceway. They weld under high load and high pressure, then they shear, leaving behind debris. That’s what creates the beginning of the peeling damage, and then it continues to create more debris, and the bearing starts to basically eat itself alive. Allen Hall: The start of that process, though — is that a lack of lubrication, or a finish or hardness issue on the bearing? Loren Walton: I love that question, because this is the crux of the whole thing, and I think it’s the part that gets missed. People immediately want to throw the whole thing out and start over with something different. Fundamentally, when we fixed the surface issue by adding the coating, the problems pretty much went away. We went from one-to-five years of life to ten-plus years, depending on the application — without changing the construction, the bearing type, or the contact angle. Just by adding the coating, we increased life significantly. The root of what you’re asking is that the bearing would operate better if it had the proper amount of separation. It’s not a fatigue issue and it’s not a loading issue. At its heart, the bearing isn’t able to create that separation. There isn’t enough speed, and there isn’t enough of a gap created by the lubricant. Allen Hall: So ideally you have this almost molecular-scale film of lubricant between the two surfaces. If it isn’t designed properly, or you have an issue, that lubricant gets squeezed out of the space, and at that point you have trouble. That’s some of what I’m hearing on main bearings — especially when turbines have been ...

A few months ago, we told you about a Houston bankruptcy court carving up TPI Composites. Well, that story just got a whole lot bigger. On July sixth, TPI walked out of Chapter Eleven. Zero debt. New owners. A private equity firm called Energy Capital Partners picked up TPI’s blade factories in Iowa and Juarez, Mexico for about twenty million dollars. Twenty million, against more than a billion dollars in liabilities. ECP did not stumble into wind blades. They bought Calpine back in twenty eighteen, inherited seventy-seven power plants, and became GE’s biggest private gas turbine customer in the Western Hemisphere. That relationship, forged in gas turbine halls, is what brought them to composite factories. GE Vernova signed a five-year supply deal requiring it to send blade orders to ECP’s factories. GE is ECP’s partner, its customer, and was even the backup buyer if the deal fell through. So TPI lives on, leaner, debt-free, with locked-in demand from one of the biggest turbine makers on earth. But now, the other side of that coin. While ECP picked up two blade factories for twenty million dollars, GE Vernova recently pumped one-point-seven billion dollars into its own blade company, LM Wind Power. LM’s equity had fallen to negative 575 million euros. Revenue dropped ninety-six percent in one year, from 2.1 billion Danish kroner down to just ninety-three million. The Danish workforce, cut to about twenty-five people. LM Wind Power has lost money every single year since GE bought it in twenty seventeen. Nine straight years of red ink. So think about that. Two American blade factories now serve GE Vernova’s onshore business. One in Grand Forks, North Dakota, owned by GE, inside a division losing four hundred million dollars a year. The other in Newton, Iowa, owned by ECP, zero debt, five-year supply deal. The independent contract blade business that TPI Composites built is gone. Vestas took the India and Mexico plants in-house. GE’s supply is locked to ECP. The OEMs and their financial partners now own the factories directly. And that is a new era for wind manufacturing. Now, let us talk about what those blades are doing once they are spinning. Earlier this month, a brutal heat wave hit the eastern United States. Air conditioners running full blast. Grid operators scrambling to keep up. And off the coast of New England, two offshore wind farms stepped up. Vineyard Wind, eight hundred and six megawatts off Massachusetts. Revolution Wind, seven hundred and four megawatts near Rhode Island. Together they pushed hundreds of megawatts into the grid right when people needed it most. And here is the number that matters. Oil-fired power plants met about ten percent of peak demand on July second this year. Last summer, at the height of a similar heat wave, oil plants covered nearly fifteen percent. That is more than a gigawatt less oil burned. The projects that survived lawsuits, survived construction shutdowns, survived lease freezes, are now keeping the lights on in New England. Across the Atlantic, Scotland just approved two massive offshore wind farms. The Caledonia North and South projects in the Moray Firth, up to one hundred and forty turbines spread across one hundred and sixty-five square miles. Enough power for two million homes. Ocean Wind is leading the development with a commitment of about 1.7 billion pounds. And here is what makes this project different. Caledonia South will mix fixed-bottom and floating turbines, up to thirty-nine floaters. That blend of proven and next-generation technology on a single project is something to watch. Back in the United States, nineteen state attorneys general are suing the Department of Defense. The reason, wind project reviews. Federal law says any wind turbine taller than two hundred feet must go through a Defense Department check, to make sure it does not interfere with military radar or flight paths. Last August, the Pentagon stopped reviewing those projects. No explanation. No timeline for starting again. Maryland Attorney General Anthony Brown is leading the coalition, joined by attorneys general from eighteen other states including California, New York, and New Jersey. They want a court to force the Defense Department to start doing ...
