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, Yolanda Padron, and Rosemary Barnes. And to lead off this week, s- there’s been some trouble in the North Sea. On July 22nd, a blade failed on one of the turbines at EnBW’s 960-megawatt He Dreiht offshore wind farm. Uh, EnBW spokesperson said there were no injuries, thank goodness, and that the authorities were notified immediately, which is generally the case in Europe. They’re very safety conscious, of course. But the machine was a Vestas V236, which is a– that 15-megawatt offshore turbine that Vestas is offering. And He Dreiht is where the platform [00:01:00] has made its debut. So Vestas and EnBW are working together on an investigation, an RCA, a- along, uh, looking at the environmental impact because parts of the blade landed in the water. And the, the images I saw online were like a sheer web that was being pulled in onto a ship, so big pieces of blade. Uh, there’s gonna be 64 of these turbines going into that wind farm, but this is probably a little bit of a weird thing because it does seem like that the wind farm is under construction when the blade broke, which is not the first time this has happened, right? That we’ve seen blade breaks at, uh, Vineyard Wind and at Dogger Bank on the GE side. Is this just a construction issue, Yolanda, you think? Or is it some sort of, uh, vibration that’s happening during construction that’s putting extra stress on the blades? Yolanda Padron: We were talking about it a little bit offline and how it might be a loading [00:02:00] issue because it’s not, uh, it’s not in the optimal operating, uh, conditions, right? Uh, but this is– It’s– I don’t like that it’s becoming a trend more than an anomaly from what we’ve seen on this podcast. Uh, Matt, I know you work a lot in solutions, right? What, what would you recommend people start doing? Matthew Stead: Yeah. I think, um, more and more there’s ways of just checking out, you know, pre-construction, um, you know, some of the vibration modes, some of the unusual, um, wind loading when it’s in standstill, you know, different yaw angles and so forth. So there, there’s more and more ways of, um, checking out what the blade is doing when it’s in those unusual, um, sort of pre-con, pre-operation phases. So, um, you know, for instance, um, we do know that there is some sort of sometimes edgewise or flatwise vibration, which, um, you know, maybe is not normal, um, and maybe could be, be [00:03:00] thought about in a bit more detail. Um, certainly I know there are some research organizations which are looking into this and also, you know, things like blade twists. Um, so what is actually happening in terms of the, um, the twisting of the blade along, along its axis. Allen Hall: I think the last time this happened, I remember going back and looking at patents about how to protect the blades during this construction phase. So you wanna prevent the blade from generating lift from sideways winds pretty much. So the designs that I saw were like putting like a, a netting across the blade to disrupt the airflow so that it wouldn’t generate lift. But I haven’t really seen that implemented. Maybe it is being implemented, but these loads are a little odd, right? I, I, I’m wondering if there’s any IEC certification test that looks into them, uh, just because it’s, it’s happened a couple of times now, more than a handful. Matthew Stead: We, we saw, um, we saw that picture of some blades on the ground. [00:04:00] You remember they were in storage. Um, there was a, a strong wind that came across them when they were in storage, and there was some, some flutter and, you know, some, some damage it caused, uh, even when they were on the ground. Um, yeah, I think just thinking out loud, you know how on some, you know, wind stacks and, or, you know, turbine stacks and, um, you know, poles, you know, exhaust stacks. Sorry, that’s the word I’m looking for. Exhaust stacks. They have the, the spiral around it. You know, it’s for around vortex shedding. So maybe it’s an opportunity for, for Rosie to jump in here and, uh, and comment. But, um, maybe we can put like vortex, uh, spiral vortex, um, you know, dissipators on the, on the blades before they’re fully commissioned. Rosemary Barnes: So it’s cer- certainly not a, a matter of the design just being a little bit wrong, right? That would mean that it would last for a, for a while and then And then break. But it, it also, it could be several things. It could [00:05:00] have been a manufacturing defect, a bad one. It could have been transport damage. Tho- those are two other things. It could have been, yeah, you know, like a, a new design feature or material that performed massively differently under real loads than what it did, um, you know, in their computer models and in their coupon tests and in their, um, static tests, fatigue tests that they did. It could be any of those things. Sometimes you do see problems where technically you’re not supposed to leave the rotor locked out for any period of time because it is not designed for the off, off-axis weird loads that you can get when the blade is oriented in a suboptimal way compared to the wind. And there have been instances where it’s like technically, you know, that was in the instruction manual, however, nobody ever followed it, and it’s only under extreme circumstances where that actually is severe enough to break it. There, there can be instances like that [00:06:00] where I would say that it- it’s pretty difficult/impossible to actually design s- for safety during any conceivable series of events during installation. The way that you would do it would be to make sure that the blade can handle any wind load and, you know, up to the maximum gust at any, at any time in any position. But having, you know, done a little bit of work, um, on blade design in my past, it is massive. That is just a massive, massive load that is y- it will never see in its lifetime. You would have such heavy, expensive blades if you actually designed it like that. Um, and so yeah, the That, that would be probably the most charitable reason for a failure where nobody really did their job wrong. It’s just kind of like some bad luck that happens every now and then. Allen Hall: Well, it does seem like there’s a trend there between Dogger Bank, Vineyard Wind, [00:07:00] some of the things we’ve seen in China. During the construction phase, those turbines are very vulnerable and the, the blades can break. Aren’t there extra precautions that could be put in place? Like, you...

Dominion Absorbs $800M in Tariffs, Nordex Profits Double
6d ago00:03:35Tap to summarizeWeather Guard Lightning Tech Dominion Absorbs $800M in Tariffs, Nordex Profits Double Allen covers Dominion’s $800M tariff hit, Eversource’s 84% profit drop, Nordex’s record quarter, and a looming floating wind vessel shortage.

And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Good Monday, everyone. Let us start this week with a number. Eight hundred million dollars. That is what tariffs on steel and aluminum added to Dominion Energy’s Coastal Virginia Offshore Wind project. Dominion President Bob Blue shared the damage on a second-quarter earnings call. Two hundred and thirty million dollars … just in the latest quarter alone. That is on top of the five hundred and eighty million from the quarter before. The project is eighty-one percent complete. Thirty-one turbines are already spinning … producing more than four hundred and fifty megawatts. But the finish line just moved. Completion is now expected by the end of twenty twenty-seven. Weather delays. Vessel maintenance. And some particularly complicated turbines to install. Blue says the project will still save customers money. And Dominion expects to pocket more than five hundred million dollars in savings from grid upgrade cost shifts. The total price tag … eleven-point-six billion dollars. Now … if Dominion is feeling the squeeze in Virginia … Eversource up in New England is feeling something worse. The utility’s second-quarter profit dropped eighty-four percent. Net income fell to just fifty-three-point-seven million dollars. Why? A one-hundred-and-sixty-four-million-dollar charge tied to the offshore wind projects they already sold. South Fork Wind. Revolution Wind. Eversource got out of offshore wind back in twenty twenty-four … but the bills keep coming. Higher-than-expected payments to Global Infrastructure Partners are dragging down the bottom line. So one company builds through the pain. Another walks away … and still pays for it. But here is some good news. Over in Hamburg, Germany … Nordex just posted a quarter that would make any CEO smile. Sales up sixteen percent. EBITDA … more than doubled … to two hundred and twenty-four million euros. Margins hit ten-point-three percent. Net income … one hundred and eleven million euros. Up from thirty-one million a year ago. And orders? Up thirty-two percent. Three-point-one gigawatts of new turbine orders in just one quarter. Their total order book now stands at eighteen-point-four billion euros. Nordex CEO José Luis Blanco confirmed the full-year guidance. The onshore wind giant is not just surviving. It is thriving. Now … let us go to sea. Classification society ABS says floating offshore wind is about to create a brand-new problem. Not enough ships. A new report says demand for large anchor-handling vessels and multipurpose support vessels will surge as floating wind projects go from small demonstrations to full commercial scale. Here is the number that tells the story. A single one-gigawatt floating wind farm needs about one hundred and ninety-eight anchors … and nearly two hundred kilometers of mooring lines. That is far more than a single deepwater oil and gas platform. ABS says shortages in certain vessel classes could hit as early as twenty twenty-nine. Global floating wind capacity is expected to grow from about two hundred and seventy megawatts today … to fourteen gigawatts by twenty forty. The race for ships … has begun. And speaking of ships … Japan just finished building one. Mitsui O.S.K. Lines held a naming ceremony in Nagasaki for the Wind Whale. Japan’s first coastal deck carrier built specifically for offshore wind. One hundred and forty-nine meters long. A flush deck designed so that monopiles, towers, blades and nacelles can roll right on from the stern. It even has dynamic positioning … so it can transfer cargo directly to installation vessels at sea. Built in China by Taizhou Sanfu Ship Engineering … the Wind Whale will carry foundations from a factory in Okayama to construction sites around Japan. A country that once built ships for oil … now builds them for wind. And finally … back home in Iowa. The state Supreme Court ruled that the CEO of Global Fiberglass Solutions can be held personally liable for dumping thirteen hundred used wind turbine blades across the state. CEO Donald Lilly and another executive argued they were never in Iowa. The court disagreed. Lilly signed the contracts. Iowa Attorney General Brenna Bird put it plainly. They were hired to recycle used wind turbine blades. Instead … they dumped them. Four hundred blades piled up along Interstate 35 near Ellsworth alone. The lesson? You can build an industry on clean energy. But you still have to clean up after yourself. So what does all of this mean … if you work in wind? It means the money is real now. Projects are not getting canceled. They are getting more expensive. And that changes the math for every engineer, every project manager, every supply chain director reading a bid today. Tariffs come and go. But an eleven-billion-dollar project does not stop on a dime. It means the vessels you need may not be there when you need them. If you are planning a floating wind project for the early twenty thirties … your vessel strategy should already be on paper. It means manufacturers who kept their discipline … who held their margins and grew their order books … are the ones writing the next chapter. And it means accountability is coming to every corner of this business. You cannot just build turbines. You have to manage the turbines. This industry asked the world to trust it with the future of energy. That trust comes with responsibility. And that is the state of the wind industry for August 3rd, 2026.

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow Allen Hall 2025: Well, Rosemary, welcome back to the show. Rosemary Barnes: Thanks, Allen. Great to be here. For, it’s been a while since we did one of these one-on-one episodes, like a, yeah, a proper, proper guest. Allen Hall 2025: Well, this is kind of a celebratory episode because your company, Pardalote Consulting, has been awarded, uh, some funding from the Australian Capital Territory’s government for the Energy Innovation Fund. Rosemary Barnes: It’s a really good program that the ACT government has to try and get energy innovation In the state. It’s not a state actually, it’s technically a territory. Little more than just Canberra, the city. Uh, but there are actually quite a few, like, really interesting energy-related companies here, partly ’cause of the, the fund I think helps, but also just tracing back like, [00:01:00] uh, y- you know, in the 20-teens, Australia had a really conservative government that hated renewable energy, and the ACT government had a commitment at that time to 100%, um, 100% renewable electricity for the, the government. And that was one of the only programs that was resulting in a lot of, um, you know, clean energy projects being built, and one of the conditions that they put on that, uh, for people that would win PPAs with the ACT was that you had to have your headquarters in Canberra. So we’ve actually got quite a few, quite a few really cool, innovative companies out of here. Um, like Neoen’s headquarters here. Windlab, uh, yeah, was, was founded here and still has a lot of people here. Pardalote obviously, and you know, a few other companies as well. So despite it being a small city of like, I don’t know, maybe it’s up to 400,000 or something people by now, um, yeah, there is actually quite a lot going on here for energy. Allen Hall 2025: And the Energy Innovation Fund is funded by the wind and solar operators in the area, and your particular [00:02:00] effort has really global consequences. You’re focusing on two areas involving how wind turbines survive Australia, but more, uh, of relevance is to just really tough conditions which exist not just in Australia but around the world. What two areas are you going to focus on? Rosemary Barnes: Yeah. So the two focus areas are leading edge erosion and high temperature fatigue, which we can probably get into the definitions of those in a minute. But basically my, um– what led me to wanna have a project like this was that when I moved back to Australia in 2021, I– and I started working in O&M, uh, I noticed that the wind turbines that I would look at, the blades that I would look at here behaved really differently to the ones that I worked with overseas. You know, es- especially with leading edge erosion, like often I would be doing a condition assessment of a, you know, a new wind farm. Um, might only have been operating for, you know, two years. That’s a pretty common time for people to get in and do a condition assessment [00:03:00] because their warranty period is about to end and they wanna, you know, make sure that everything is okay. Um, and I would just notice that often, like 90, 100% of blades would already have bad erosion after just a couple of years, which is super-duper fast. And then there are some tools available to check, um, like what kind of erosion are you likely to experience on your site. Like is it a higher severity erosion site or a, a low severity one? Um, and you basically, you know, the status quo globally is to just look at the annual rainfall, um, and the tip speed. And if you’ve got, you know, high for both of those, that’s a bad erosion site. And if you’ve got low for both of those, it’s a, a low erosion site. But when I plotted out the wind farms that I knew had really bad erosion problems onto, you know, a chart with those two axes, I just saw a random distribution of dots. You know? Like, this was not– uh, this had no predictive value for Australian wind farms. And so that led me to believe that, okay, um, you know, things are a bit [00:04:00] different here. Makes sense, you know, most of the knowledge that we have about how wind turbines operate, it’s been developed and validated mostly in Northern Europe. You know? Like it’s, it’s Denmark and the surrounding countries that had, like, the bulk of the early wind energy. First few decades of knowledge were, you know, were mostly there. Of course, there were some other, um, places that had wind turbines, but, you know, most of the The OEMs have been operating for decades, came from Denmark. And I know when I lived in Denmark, the rain there is very different to the rain in Australia. So in Denmark, it’s basically always raining, right? Like, it’s just… Like, even if it’s not raining, you’re still gonna get wet when you go outside ’cause it’s just, like, the air has this just amazing ability to just hold onto moisture. Um, but it’s very, very gentle. But, you know, over an entire year of most days having gentle rain, that adds up to a lot. Whereas in Australia, and especially if you go, like, north to Queensland, it rarely rains. It’s mostly just dry, and when it [00:05:00] does rain, it’s like a tap turns on, and I, I swear you will get bruised from the rain droplets hitting your skin. You know, they just have so much energy in them. So I think that that i- you know, when you look at just the overall rainfall, you really hide something important about how erosion, um, can progress. Then, um, there’s other places in Australia that have very different characteristics. Again, they don’t have that kind of really intense rain but, you know, some of those sites are also having really bad erosion. And so it just occurred to me, I did a lot of research, you know, into what’s going on and, you know, the academics are studying erosion a whole lot, and they’ve got, you know, a lot of standardized tests and, you know, products are developed according to these standardized tests. But the standardized tests don’t actually resemble reality, and especially they don’t resemble reality in Australia. And so my client started asking me, “Okay, you know, the products that we have are, are terrible. We have to replace them every couple of years. It’s, um, causing big problems with also [00:06:00] the amount of energy that you’re losing.” One of the types of, um, leading-edge erosion or leading-edge problems that we have in Australia is that the, the coatings tend to peel off and make these, like, big flakes which will just massively disrupt the airflow, can cause y- you know, at least a few percent AEP loss, and maybe up to five. And even worse than the AEP loss is the revenue loss because it affects it most at, you know, lower wind speeds. Um, you ...

Pullman East Melbourne. And it’s packed full. Our, in fact, actually, we have so many people applying to attend the event, we’re getting a little nervous on if the size of the venue is not large enough, and we, we have a lot of people already chime in wanting to be sponsors, which is great. But I wanna talk about what you will experience at WOMA. We’ve done it for two years now, and the feedback has been great. And Yolanda, you’ve been to the one just this past February, and participated in panels and saw some of the, uh, workshops and was involved in a lot of WOMA 2026. What are you expecting in 2027, and what did you think of 2026? Yolanda Padron: I thought [00:01:00] 2026 was great. I loved seeing everybody there. Uh, got to meet a lot of new people. It was, it was sweet. There was a lot of r- people returning from WOMA 2025, um, and a lot of new people that were told that that was the event to be at to learn about wind, which was really, really nice to hear. Uh, something that I loved, especially since we’ve been through quite a few conferences since then and before then, was just the fact that, like, you’re, you’re just talking about problems and just talking about solutions, and you’re talking about real stories, and it’s nothing that’s super, super public. You know, like, you, you can have real conversations with real people. I know during a panel I mentioned a, a solution to an issue that I had seen that was kind of niche, and then, uh, like three minutes later, like I had had some people come up to me and we all talked about the problem that we saw and then [00:02:00]talked about their problem, and it was really similar, and obviously in a totally different continent. And it was, it was good to, to be able to have those conversations that you usually wouldn’t have elsewhere, especially if everything’s just really, really public and just big and you’re having a lot of people sell at you, and it’s, it’s just something that we’ve really shied away from. What, what was your favorite part of it? Matthew Stead: I, I think, um, it was really the fact that it was a a technical, useful, helpful conference rather than having some rando talking about things that they’re told to talk to you about Allen Hall: It’s real answers from real problem solvers.

I’m here with Rosemary Barnes, Matthew Stead, and Yolanda Padron. It’s been a busy day as we record because GE just announced its second quarter earnings and a bunch of things about the business. They had an investor call early, early, early on the East Coast, and even earlier for those on the West Coast of the US, and it was a very good quarter for GE, but a really lopsided one. Uh, GE Vernova reported second quarter orders of [00:04:00] $24.2 billion, up 88% with a backlog that has now climbed to $176 billion. Free cash came in at $5.1 billion. Man, $5.1 billion is a lot of cash, everybody, which is more than the company generated in all of last year. So they made more in one quarter in cash than made in all of last year, and management is raising its full year guidance, but the strength is coming from gas power and the electric grid, not from wind. The wind segment saw orders fall 40% and revenue slip 10%, and the company still expects wind to lose about $400 million this year. Although in the investor call, they did say that the forecast for wind in Q3 and maybe even Q4 was to be essentially break even on the EBITDA scale. So that’s a, a, a good number. It does seem like GE is being more [00:05:00] aggressive on pricing and selective on the projects they are choosing to participate with. Repowers was way down, if I remember correctly. Uh, they are not doing a lot of that at the moment. So there is a slowdown they’re seeing in wind, but they’re more than making up for it in gas turbines and electrification. Orders for gas turbines are out to ’30, ’31, and I think they’re gonna close out all of ’30, ’31, um, book orders for gas turbines here shortly. So if you want a gas turbine, Matthew, you’re gonna have to get in line because your GE has a long list of, of clients in front of them. What does this mean for wind? When I hear the discussion where GE is focused on gas and electrification because of the huge cash flow that comes in their door- Does that mean a good positive things for wind because they have the cash to kinda hang around wind? Or is it gonna be set aside for other [00:06:00] more profitable business segments? I Matthew Stead: mean, GE’s had a number of setbacks over the years. Um, you know, we know, we know all about them. We’ve been talking about them, you know, multiple times. But, you know, they’ve gotta just wait it out, don’t they? Um, you know, wind is not gonna go away, so they just need to wait it out, get their problems out of the way, get their cash flow in, build the order books again, just wait for things to improve. Um, I, I think one thing I just wanna pull out, the Sands Ear, i- isn’t that a massive achievement? Allen Hall: It is. It’s, it’s a colossal engineering achievement on its own. Forget about just delivering and manufacturing all those turbines and getting them installed. And that’s a pattern energy project, and Fairwind I think was involved with that in terms of project development, EPC items. It’s huge. It’s gigantic. But it may be the last one we see in the United States for a while. Matthew Stead: And but Vineyard, you know, they’ve gotta resolve that, don’t they? We’ve spoken about that before. Get that one out the way, clear out the decks and, yeah. That’ll come good. Allen Hall: Rosemary, of our former GE [00:07:00] employees, I guess we have two of them here. I’m one. Not of wind, but of another division. What’s your thoughts on GE Vernova at the minute? Ros...

Happy Monday Everyone The V236 just had a bad week last week. a blade failed on one of the turbines at ENBW’s [EN-bay-vay’s] HE DREIHT [hay DRYT] offshore wind farm in the German North Sea. Nine hundred and sixty megawatts. There are 64 of those V236 machines. The project hit first power just last November. ENBW says no one was hurt. VESTAS says it has launched a root cause investigation. But a blade failure on your flagship turbine … at one of Germany’s biggest offshore wind farms? That will be a headline. And the industry is watching. Now … from the North Sea … to the coast of Maine. The UNIVERSITY OF MAINE has done something no one in America has done before. They put a full-size floating wind turbine in the ocean. And it is delivering power to the grid. The platform is called VOLTURNUS [vol-TURN-us]. It was assembled onshore … in Brewer, Maine … then towed thirty miles down the PENOBSCOT [peh-NOB-skot] River and out to sea. No specialized heavy-lift vessels. No deepwater pile driving. The hull is made of concrete … sourced locally. Not imported steel. Eighty percent of the best offshore wind in America sits over water too deep for fixed-bottom foundations. Floating platforms like VOLTURNUS could change that math entirely. Meanwhile … in Japan … wind energy just found a brand-new customer. Data centers. EURUS [YOO-rus] ENERGY and TOYOTA TSUSHO [TOY-oh-tah TSOO-shoh] have broken ground on a wind-powered data center in HOKKAIDO [hoh-KY-doh]. It is the first data center in Japan directly connected to a wind farm. The facility sits next to the KOBAOKO [koh-bah-OH-koh] Wind Farm … forty-two megawatts … with a private power line running straight to the servers. And here is the bigger picture. Japan has most of its data centers packed into Tokyo and Osaka. HOKKAIDO has the wind … but not the demand. So instead of sending the power somewhere else … they are bringing the demand to the wind. TOYOTA TSUSHO already operates ten wind farms in the region … more than five hundred megawatts. They are planning a much larger data center cluster by twenty thirty. Ten to twenty megawatts of capacity. And speaking of scale … China just laid out its five-year plan for renewables. The target? A fifty-three percent jump in renewable energy consumption by twenty thirty. According to BLOOMBERG … renewable power use should rise to about one-point-eight billion tons of coal equivalent … Wind and solar generation alone should nearly double … from two-point-three trillion kilowatt-hours to four trillion. And here is the part that matters for reliability. China wants wind and solar … backed by storage … to provide twenty percent of electricity during peak summer and winter evening hours. That is double the current level. Three hundred gigawatts of peak generation from renewables. That is not an aspiration. That is a published national target. Now … before we go … a story from the other end of the scale. In KONGIGANAK [KAHN-gig-uh-nak] … a village in western Alaska … they built five wind turbines. There is no grid connection. No transmission lines running to the outside world. For years … the village ran on diesel generators. The turbines changed that. But they created a new problem. Sometimes … the wind made more electricity than the village could use. No grid to send it to. No big battery bank to store it in. So the engineers came up with something simple. They put special ceramic heaters inside every home. When the wind blows hard … the extra power flows into those heaters. Dense ceramic bricks soak up the energy as heat. And when the wind dies down … that stored heat slowly releases into the house. In Alaska … where winter never seems to end … surplus wind power now keeps homes warm and cuts diesel bills at the same time. There is a shift in the wind energy business at the moment. It used to be utilities buying megawatts. Now it is tech companies buying uptime. Remote villages buying independence from diesel. And entire nations buying credibility on their climate commitments. Each of those buyers has a different definition of reliability. And every one of them needs turbines that can run for years and years. The wind industry has never had more demand. <p class="...

So Matt Sagala has not been on the Uptime Wind Energy podcast. Although he’s been asked for the last five or six years to be on, he has had other commitments. So now that he’s available to be on the podcast, we love having him here. Uh, if you don’t know Matt Sagala, Matt Sagala is a, a real special talent in wind. Very knowledgeable about repairs. He’s a composites person, but he, you know, it’s one thing to know composites and understand what that looks like, but also to run organizations that repair blades and manage blades and take care of large quantities of blades and do it very efficiently, where the assets are actually working and operating efficiently is hard to do. So, uh, [00:01:00] Matt is now with SkySpecs in a recent change from a, a large global wind operator, and he’s come over to SkySpecs as Director of Asset Management. So Matt, congratulations first. Appreciate Matt Sigala: it. Appreciate it. Allen Hall 2025: So that’s a, that’s a big title there. What does that all mean, Director of Asset Management at SkySpecs? Matt Sigala: basically, it’s just the overview of your entire asset from the start of the inspections to the reviewing of, of the inspections, to creating the RFP, going out to blade budgets and repairs, uh, and then having the actual repair teams on site and us being able to help execute those repairs in a systematic way, um, without having to overload or, or burden your, your internal, uh, systems in-house. Allen Hall 2025: Because as an operator, there’s a lot on your plate. Matt Sigala: Yes. Allen Hall 2025: And a lot of operators don’t necessarily have blade teams internally. You came from an organization- Yeah … that did have a really good, still does have a really good blade organization. Matt Sigala: Oh, amazing, yeah. Allen Hall 2025: Yeah. Uh, that was unique, but a lot of operators in the United States or globally just don’t have [00:02:00] that resource. SkySpecs has developed that resource over the last couple of years of we’re blade experts, we have all the data coming in, but we can also help you downstream when it comes to maintaining and repairing blades, which is, is sort of a new feature for- Yeah … SkySpecs. Now that you’re there and you’re seeing all the data, all the, the, the- the, data center, so to speak, of w- and you have access to blades globally, and you can put your fingers on it. What are you seeing out there in terms of blade health and, and going forward? Matt Sigala: There’s a lot of work. There’s definitely a lot of work upcoming and into the future. Um, and you know, I think a lot of it could be risk-based with, with inspections, annual inspections, semi-an-annual inspections. I think that’s always the first line of defense on any blade management c- campaign. Um, and then, you know, coming behind that, I think that’s where our preferred vendor lists and, uh, you know, being comfortable with working with certain suppliers on certain type of repairs. Um, we feel that, you know, we have an edge on the industry, [00:03:00] uh, with the data set that we have in hand, plus being able to build a relationship with ISPs. And not only build a relationship with them, but be able to continuously give them mindful insight to their repairs from a year now to two years now. Because we’re the only ones really seeing those inspections and the repairs after they’ve been in operation for more than a year. It’s very rare that a, an ISP, uh, even on my side of the house when I was working with EDF, of being able to see a repair from year to year. Um, I think that’s, that’s, that’s pretty massive and- Yeah … a lot of value within that, so. Allen Hall 2025: Oh, sure. Uh, you were one of the first ones when I met you years ago now, uh, that was a big proponent of more inspection. Yeah. That there are some blades in which you must inspect more. Matt Sigala: Yes. Allen Hall 2025: And here’s the reason why. Matt Sigala: Yeah. Allen Hall 2025: Because you had thought through it a little bit and you’d come up with a plan. So you always had a plan. That’s one thing about Sagales, he always has a plan. You can ask him any question, he’s got a plan in relationship to blades. And you were the, you were the one that has said, “Hey, uh, there are certain blade types out there that we have seen that, well, you need to do a [00:04:00] little more inspection, and there are some others that it’s totally fine.” Yeah. A, a yearly inspection is, is, is fine. Well enough. And that SkySpecs data, now that you have access to it, is that also f- feeding back into your- Definitely … logic of that? Matt Sigala: Yeah, yeah. How do you, how do you think about it? No, it’s, it’s, it’s opened my mind a lot kinda getting me out of just being in, like, the trenches of certain decisions and being able to see this whole data set as a whole now. Uh, and holistically, it’s like, all right, m- there’s just certain things that I kinda need to adjust on my end. Um, definitely letting a lot of things just play out for, uh, this repair season and, and how things are running, and then kinda looking to make some changes into, into ’27. Um, but the data set, it’s, it’s amazing. It’s, it’s almost over- overwhelming. Um, so just kinda going after- the low-hanging fruit as far as, like, the 62 twos, the 145s, and really understanding what those look like, uh, how we can help our customers Allen Hall 2025: that’s a large part of the fleet in the States, but globally too. SkySpecs has made a lot of, uh, recent advancements into, uh, certain marketplaces outside the US. Mm-hmm. I won’t go into the specifics there, [00:05:00] but e- essentially, like, SkySpecs is becoming definitely more of a global company than a US-based company. Uh, and seeing turbines from outside the US, so you see a, a GE or a Vestas turbine operating in Germany or in the UK, and you see the same turbine in the States. They’re not- No … performing the same, are they? No. It’s a completely different- Same turbine. Matt Sigala: Yeah, different wind regimes, erosion characteristics, crack propagation rates, everything. Even we were se...

I’m your host, Allen Hall, and I’m here with Rosemary Barnes, who is recovering from a very serious illness, Matthew Stead, who has been healthy pretty much all the Australian winter, and Yolanda Padron in sunny, hot Austin, Texas. Welcome, Rosemary Rosemary Barnes: Thank you. I am recovering from man flu, and I say man flu because it’s just a cold, but I’m complaining a lot about it. Allen Hall: there’s gonna be a new name for Siemens Gamesa. So it was Siemens and then Gamesa’s a separate company. They merged. Siemens Energy, uh, broke off from Siemens AG. So [00:01:00] that’s a very well-known name, Siemens. It’s– Everybody knows Siemens at this point around the world. And the, the one family had, as a company, had s- label on everything, right? So it’s, uh, Werner von Siemens started it 150 years ago. It’s been a long time since Siemens was started, but it’s everywhere. It’s on turbines, transformers, and power plants around the world, and now they’re changing their name, right? So when Siemens Energy broke off from Siemens AG, they, they had a limited time they could use that name, so they have rebranding themselves or are about to rebrand themselves, and I wanna pronounce this right, Omterra. O-M-T-E-R-R-A. Now, we did a little research on this, and I think it’s Latin for all of the world. It’s kind of a conjoined, uh, set of words, Latin words, kind of a, a schmear in a sense. So, uh, so the company that, you [00:02:00] know, that spun off in w- roughly 2020, if I remember this right, Matthew, does that sound right? It was roughly 2020 when Siemens Energy was established on its own. Uh, they’re gonna be changing their name to Omterra. So instead of seeing, seeing Siemens Gamesa publications or Siemens Gamesa wind turbines, I guess they’re gonna have this new name, Omterra. What do we all think? Matthew Stead: I think it’s great. I think, and if you go back to, you know, GE Vernova, um, I, I thought Vernova was a bit weird for a while, but now it just rolls off the tongue and easy. It just makes so much sense. Um, so I’m, I’m, I’m for it. I, I like it. I’ve already… You know, can already say it. It took a lot longer to say Vernova than it’s taking to say Terra. Rosemary Barnes: I think that it– But it’s not Vernova, it’s GE Vernova, right? So everyone knows what it is. Whereas my understanding is it’s not Siemens Omtera, it’s just Omtera, which makes it sound like a new budget kind of [00:03:00] brandless, history-less, uh, company. So that’s… Yeah, I’m no branding expert, but I think that, uh, like they, they must have not been able to use the word Siemens at all, um, because otherwise you surely would, because it has a very… Outside of, you know, their blade issues and bearing issues of a couple of years ago, they do have a, like a solid engineering reputation across many fields, so you wouldn’t probably intentionally divorce yourself entirely from that. So, um, yeah, I, I think it will take some getting used to for me Matthew Stead: but everyone remembers. I mean, it’s not like– The people in the wind industry know their heritage, they know their history, so I don’t think it matters. I mean, you know, you know, they, they purchase the Senvion, you know, technologies or, you know, licenses in Europe. You know, y- y- you don’t forget these things, so I don’t think it matters. I think it’s just a, it’s a color, it’s a, it’s a label Yolanda Padron: I think it’ll be fine. I just think that there will be a little [00:04:00] bit of confusion down the line as with everything, right? Like I’ve, I’ve been on the side of conversations where I have to explain like Siemens versus like SGRE on paper and it’s like, oh, it’s– this is why th- there was that paper trail, uh, because people would think it was an absolutely different thing. Um, so I, I can totally see those conversations coming, coming to play in the future where someone thinks that Ontier is a completely different entity that maybe they changed OEMs or something, um, for a site. But nothing a little history lesson won’t fix, I guess. Matthew Stead: You just want people talking about you Rosemary Barnes: Name change every year Allen Hall: Change your name every year. Well, that’s, that’s one way to approach it. I w- always wonder what the boardroom looks like and sounds like when this discussion is going on, because Siemens, Siemens Energy is a big company, and there had to be outsourcing of this to probably several marketing firms, mostly [00:05:00] in Germany, I’m guessing. And they came back with a bunch of pitches, and eventually they picked one. But boardrooms are probably not the place to pick a name. And I always think like, “Oh, you just had such a opportunity to do something really cool or really impressive.” Allen Hall: Well, we’ll see how it goes with Omterra. The, it’s gonna be, I’m sure, a huge marketing effort, and you’ll probably see commercials for it during the Super Bowl. Developers are [00:06:00] eyeing Britain’s next big renewables auction and have been waiting to learn the rules and most importantly, the price. Well, this week the UK government delivered both. It confirmed a package of changes to the CFD scheme ahead of allocation round eight, aimed at simplifying the process and keeping good projects from being tripped up by some paperwork. So AR7 was super successful, and they’re hopefully gonna have a, a great allocation round eight. Uh, unchanged from last round, here are some pieces to it. AR7 brought in 15 gigawatts of, of new capacity, uh, well below the ceilings, and the government is betting that that’s stability from AR7’s gonna exist for AR8, so they’re keeping the pricing limits the same. And let me give you some of the numbers here. So everything’s in 2024 prices, just so we have a baseline here. It, 113 pounds per megawatt hour [00:07:00] for fixed bottom offshore wind, 271 pounds for floating offshore wind. That’s, uh, pounds per megawatt. And then 92 pounds per megawatt for onshore wind, and s- 75 pounds per megawatt for solar. So 271 pounds per megawatt hour in 2044 dollars is, you know, you’re probably talking, what, 290 pounds per megawatt hour. That’s a really good strike price or ceiling to allow, uh, some more floating wind into the UK waters Rosemary Barnes: Yeah. Well, the UK have this newly si...

And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Good Monday everyone. 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 its job again. And finally, a story from the sea floor. Down in southern New England, lobster populations have been falling for decades. Back in nineteen ninety-eight, there were about fifty million lobsters in those waters. By twenty twenty-two, fewer than ten million. But something else is moving in. Jonah crabs. Fishermen used to throw them back. Now they are hauling them in by the thousands, selling them as a cheaper option to lobster. And researchers at the University of Rhode Island are finding that offshore wind foundations are acting like artificial reefs. Algae grows first, then barnacles and mussels, then fish and crabs follow. The question scientists are working to answer is whether these structures create new marine life, or just pull it in from the surrounding ocean. Either way, the turbines are not just making electricity. They are making habitat. Now, here is what to watch. This Wednesday, July twenty-second, GE Vernova reports second quarter earnings. And the numbers we just talked about will be in the room. One-point-seven billion dollars pumped into LM Wind Power, a blade company that has lost money nine years straight. Twenty million dollars to let ECP walk away with two factories and a five-year supply deal. GE Vernova is guiding for four hundred million dollars in wind segment losses this year. Meanwhile, its Power and Electrification divisions are printing money, nearly five billion dollars in free cash flow last quarter alone. So the question on that earnings call is simple. If you are spending eighty times more to keep your in-house blade maker alive than a private equity firm paid to buy your contract supplier, how long do you keep doing both? Watch for what GE Vernova says about LM Wind Power’s future, about North American onshore blade strategy, and about whether that 1.7 billion dollar injection was a rescue, or a goodbye. The answer could reshape who makes blades in this industry for the next decade. And that is the state of the wind industry for the 19th of July, twenty twenty-six. Join us for the Uptime Wind Energy Podcast tomorrow.

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 curtailed and aren’t turning. Is that partly just the fact that there’s so much load? Cory Mittleider: I think that’s a fundamental difficulty of the main shaft bearing. You’ve got extremely variable loads, from full load to idle, and a wide range of operating conditions — from northern North Dakota in the winter to Texas in the heat this week. High load, heavy load, incredibly slow speed, and even slower if it’s idling. It’s hard to reliably build that film. It’s not necessarily that there isn’t enough lubrication; it’s that the film isn’t building properly where it needs to be to separate the metal and the rolling elements. Allen Hall: So the diamond-like coating was meant to solve that welding problem — you put the coated bearing in, and it worked okay until more recently, when all of a sudden we started having other issues. To me those aren’t related to the coating itself, but to other things happening up in the nacelle. Loren Walton: If we recall some of your previous episodes, you were on the forefront of understanding and talking about DLC starting to become an accelerant to failure. I know you talked about it with Cory. Those episodes have aged very well. A lot of people now are recognizing what we were saying years ago and changing their strategy toward removing DLC — whether on bearings for newer turbines, typically two megawatts and greater, or in some cases going backwards and removing DLC as they do additional replacements, and looking for another solution, because there’s potential for additional issues you weren’t expecting by adding the coating. Allen Hall: The coating is non-conductive, which is part of the issue, because you wouldn’t think bearings are conducting electricity. But as turbines got some of these uptower and downtower converters and inverters connected to the generator, we started seeing current levels — according to Motor Doc, where people like Howard Penrose have gone out and measured currents in the nacelles — of well over a hundred amps running through ground straps and the like, into bearings. That’s a lot of current. If you’re shoving that into a bearing that has DLC on it, you’re going to break it down and create these really hard steel bits stuck inside the bearing, which wear it like pouring sand inside a bearing. That’s what eventually happens, and it has nothing to do with the bearing. It has more to do with the electrical and control systems we stuck up top...

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 that are getting trained. But there were heaps of techs in this course. There were maybe eight or so, which is also part of the reason why it took a really long time. Allen Hall 2025: So [00:04:00] this week, as we record, y- you’re presenting a blade repair course for engineers and technicians. a completely new area that you’re, uh, going into in terms of offering advice and expertise that it’s really hard to find on the planet. It’s probably a, a, a busy or, or requested course, I would imagine, in Australia, where you just don’t have access to a lot of the manufacturers. Rosemary2: it’s a, it’s a course for just for engineers or technical type people, um, but including hands-on stuff. So the way that I I forced this to come into being was just the last five years. I, um, you know, I started working a lot on wind turbine blade repairs and, um, people would ask me, you know, “Have these repairs been done right?” And the thing is that the only repairs that I had anything to do with when I was working at LM were weirdo ones, right? [00:05:00] Where the normal, like a technician couldn’t, couldn’t handle it. It was outside of, um, yeah, their, their standard, uh, kind of repairs that they can do for whatever reason. and now in the work that we do at Part Load, it’s primarily normal repairs, and I just didn’t know exactly what technicians know. You know, how do they, how do they know whether they can repair it or not? What do they know before they go up there? When are they calling the engineer? Um, all that sort of stuff, like the normal stuff. eventually it became less about me learning, ’cause like I said, I kind of picked up most of it. Um, but now I’ve got staff that I’m training up to be, uh, you know, composites engineers and to work with these kinds of issues. There’s a lot of repetitive tasks involved in what we do when we, like, assess the condition of a wind farm. A lot of what we do is look main- manually looking through photos and thing- if things are classified right or not. I [00:06:00] Found this guy from Direct Wind Services, Jurij Eska. He’s a blade engineer. He’s worked in Europe and then come back to Australia, so a little bit like me. And, um, I just worked with him on a few projects and I’m like, “Oh, okay. Well, this guy, uh, he really ...
