    TPI Blade Factory Bids, Vestas Wins Offshore Deal

    Allen covers Vestas’ turbine supply deal with RWE for the 1.4 GW Vanguard West offshore project in England and its bid for TPI Composites’ blade factories in bankruptcy court. Plus Germany’s Nordlicht One foundations arrive ahead of schedule and Enel buys $1 billion in US wind and solar assets.

Vestas. And this week … Vestas had itself quite a week. On one hand … the Danish giant just locked in a deal to supply ninety-two of its massive V236 turbines to RWE’s Vanguard West project off the east coast of England. One-point-four gigawatts of offshore wind. Each turbine … fifteen megawatts. That project just won a Contract for Difference in the UK’s Allocation Round Seven. RWE and its partner KKR want a final investment decision by this summer … and power flowing by twenty twenty-nine. And this is part of something bigger. RWE signed preferred supplier agreements with Vestas back in December of twenty twenty-three for the entire four-point-two gigawatt Norfolk Wind Zone. That is three massive projects … off one English coast. So Vestas is building turbines for the British. But here is where it gets interesting. Over in a Houston bankruptcy court … wind blade maker TPI Composites has been carving up its assets since filing Chapter Eleven last August. A firm called ECP V acquired the bulk of TPI’s remaining operations. They were the only bidder. The auction … canceled. But certain facilities in Mexico and India? Those were carved out of the deal entirely. And the company circling those assets? Vestas. The very same Vestas building turbines for England has put in its own qualified bid for the blade-making plants that once served it as a customer. So while one hand signs turbine contracts … the other reaches into bankruptcy court to secure its own supply chain. Now … across the North Sea in Germany … the Nordlicht offshore wind cluster just hit a milestone of its own. The first monopiles and transition pieces for Nordlicht One … finished ahead of schedule. Sixty-eight foundations. Each monopile … eighty meters long. Nearly thirteen hundred tonnes of steel. When complete … Nordlicht One will be Germany’s largest offshore wind farm at nine hundred and eighty megawatts. Combined with Nordlicht Two … the cluster will generate six terawatt-hours of clean electricity every year. And then there is Italy’s Enel. The power giant announced it is buying eight hundred and thirty megawatts of American wind and solar assets from Excelsior Energy Capital … for one billion dollars. That deal closes later this year. And it will push Enel’s North American renewable capacity to thirteen gigawatts. Globally … Enel Green Power now commands sixty-eight gigawatts of clean energy. So let us step back and look at the picture. A Danish turbine maker wins a massive English contract … while quietly bidding on bankrupt blade factories to protect its own supply chain. German foundations arrive ahead of schedule. And an Italian energy giant bets one billion dollars on American renewables. From the North Sea to the Gulf of Mexico … from English coastlines to Houston courtrooms … wind energy is not slowing down. It is building … faster. And now you know … the rest of the story. Good day!

This is the, the final event of this three day marathon. Uh, where will we be in five years? And I have, uh, pretty much everybody from the Uptime podcast and Thomas Schlagel from eLog Ping. Uh. Uh, Rosie and I had a big argument before we all came about what we were going to be in five years, and Rosie’s and my opinion differed quite a bit just on, that’s, uh, that’s what led to me suggesting the personality test because yes, and that was, that’s actually a really good suggestion. So I know something about myself now, but, uh, I, I think talking to people here, watching the presentations. And having an American slash European perspective on it. I think every, everybody can chime in here. Australia’s probably on a better pathway than a lot of places. Yeah. Well, I know I’ve been back in Australia for about [00:01:00] five years, five years. Before that I was in Denmark. I left Australia. Because I was so like in despair about the state of renewables and also manufacturing and just doing smart engineering in Australia. Um, so yeah, when I came back five years ago, I was a bit shocked at how different things were in Australia. And I was also, you know, like I will say that it, we were, we were behind like way less mature than other, um, markets in terms of how we operated our wind energy assets. Um, and it’s changed so much in five years, so like a half day, if I’m making predictions for where we’ll be in five years time, I have to, you know, like use that as a, it, it’s probably gonna be more than you would think in five years, just based on how far we’ve already come in, in five years. Um, so yeah, I think that five years ago people were trusting a lot more in the full service agreements. Um, definitely there’s very few people who are still naive that that’s just, you know, um, a set and forget kind of thing that you [00:02:00] can do and not worry about it. Everybody’s now aware that you need to know, um, about your assets and we’re already to the point where there are like a lot of asset managers know so much, um, and, you know, have become real experts and really wasn’t, wasn’t the case five years ago. So. I’m hopeful for that. Um, you know, that it, it will continue and yeah, probably at a faster pace than, um, what we see elsewhere. I think Australia is a really attractive market, not just for developing new wind projects, but also for developing all of the kinds of supporting technologies, which is, you know, like a lot of the people here either using or developing those kind of technologies. And some of our challenges here make it the perfect place to, yeah, develop new text because. Things are, it’s really expensive to do repairs here. Um, the operating conditions are harsh and so things wear out and it just means that it’s, you can put together a positive business case for a new tech here much sooner than you could overseas. So I’m really [00:03:00] hopeful that we see, you know, like a whole lot of innovation, um, in, in those kinds of technologies that are gonna help wind energy get a lot more mature. And even hearing some of the answers from last year to this year, you see that shift. Uh, I was really shocked last year how much reliance there was on. The FSA and now I hearing a lot more discussion about, all right, we need to be shadow monitoring. We need to be looking at the, the, the data coming off, trying to hack, break into the passwords to get to the SCADA system, which was new, but I feel like very Australian thing to do. Matthew, you’ve been in the small business in Australia for, for several years in the wind business. What do you see? I mean, you’ve been in it like for five years now. Plus actually more than that, uh, I actually did my first wind farm around 20 oh 2001. Okay. Or 2002. Um, that was from a noise perspective. So I, I’ve seen things, you know, the full cycle. Um, you know, there were many years of [00:04:00]despair, the whole, um, stop these, stop these things. I’m actually featured, I was featured on Stop these things. So, um, don’t, don’t Google it. It was pretty horrible. So, um, we did a lot of work around infrasound and noise impacts and so there was many years which were, were pretty horrible. Um. Over that time, I sort of relate to my daughter. My daughter’s turning 21 soon. She is a beautiful girl, turning into an adult, a wonderful adult, and it’s, I think the wind industry is really growing, maturing, growing up, and you know, is wonderful to see. And I think we are, we’re only gonna get better, stronger. And I think one may, one note I made here is that now they’ve got wind, solar batteries. I just think it’s unstoppable, so I’m super optimistic that we’re only gonna keep, you know, raising that bar. Well, if you look at where Australia is compared to a lot of the places on the [00:05:00] planet, way ahead, in terms of renewable energy. I mean, you’ve got basically $0 in electricity for, because of how much solar there is, plus the batteries are coming in and, and the transmission’s coming online. And I’m talking to some people about, uh, what these new developments look like. If you’re trying to develop some of these projects in the United States, you’re not gonna be able to do them. There’s, there’s too many regulatory hurdles, and it seems like Australia has at least opened some of the doors to explore. Uh, people in America, the companies in Europe are gonna be watching Australia, I think in, in terms of where we go next. Because if Australia can pull off pretty much a renewable grid, which is where you’re headed, others will follow because it’s just a lower cost way of running a, running an electricity grid system. Yeah. Now I need to perform my, um, regular role of being a Debbie Downer. Um, I, I think that there’s, there’s big challenges and it’s definitely not, um, a case of [00:06:00] the status quo now is good enough to carry us through to a hundred percent renewables. Um, there are some big, big problems that need to be solved. Like, uh, solar plus batteries in Australia is, is going amazing and it’s gonna do a lot. It’s not gonna, it will be incredibly hard to get to, you know, a fully renewable grid that way. The problem with wind is at the moment, I mean, it’s getting more expensive to install wind now and we don’t only need to install new wind farms, we’ve also got existing wind farms that are retiring. So we need to either extend those or we need to, um, you know, build new wind farms in their place. So we do need to get better there. And then I think that the new technologies, like, you know, I’m the blades person and the bigger blades are bigger problems like, like dramatically. I don’t think that your average, um, wind farm owner or wannabe wind farm owner is aware, like actually how many more problems there are with big blades compared to smaller ones and. I think that, like I said earlier, I [00:07:00] think Australia’s a great place to get those technologies, um, you know, developed. But we, we need to do that. That’s not like a nice to have and oh, everything will be a little bit better, but if we can’t maintain our assets better and get more out of them, um, we also need improvements with manufacturing. But it’s not really an o and m thing. I won’t talk too much about it. But yeah, I think that like we can’t be remotely complacent. Well, I think in, in Europe, uh, Thomas, you actually spent several months in Australia, and you’re obviously from Austria, so it’s an Austria Australian connection. Do you see the differences between the Austrian market, the German market, and what’s happening here in Australia? What, what do you think of the comparison between the two? So, what I, what really was fascinating from was the speed of, um, improvements we see here in Australia. It. Um, just for me, wind industry in my young industry, sorry, was always rather slow in Europe and [00:08:00] like not really adopting. Um, and here, sorry. For example, last year you asked the question how many. Of the audience to use sensors for shadow monitoring and no hand was raised right. It was zero silence. And uh, this year we even had a few percentage on, on sensors on the, on the cido. So you see only within a year like this gradually graduated, improvements are happening and I think that makes such a, um, speed in, in improvements and that will. Close to the rescue again. Thank you. And that, um, that will bring Australia to a big advantage. Um, especially I think overtaking, uh, at a certain point, and it would be great to see in five years from now, um, maybe Europeans, Austrians, uh, coming to Australia to. [00:09:00] To learn and not the other way around. Yeah, and, and especially with Yolanda working for the biggest energy company in Denmark, uh, in America, you see how Americans react to change and, and the reluctance to move forward on some of the things we talked about this week, which are, do seem to be moving a little bit quicker. There is more an acceptance of CMS systems here. And on in the States, it seems like you have to really fight. A lot of times to get anybody to listen, to do some

    Australia’s Wind Manufacturing Push, Ming Yang in Scotland

    Allen, Rosemary, and Yolanda discuss Ming Yang’s proposed $1.5 billion factory in Scotland and why the UK government is hesitating.

Visit strike tape.com And now your hosts.  Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host Allen Hall, and I’m here with Yolanda Padron and Rosemary Barnes, and we’re all in Australia at the same time. We’re getting ready for Woma 2026, which is going to happen when this release is, will be through the first day. Uh, it’ll, it’s gonna be a big conference and right now. We’re so close to, to selling it out within a couple of people, so it’ll be a great event. So those of you listening to this podcast, hopefully you’re at Wilma 2026 and we’ll see, see you there. Uh, the news for this week, there’s a number of, of big, uh, country versus country situations going on. Uh, the one at the moment is [00:01:00] ING Yang in Scotland, and as we know, uh, Scotland. It has been offered by Ming Yang, uh, to build a factory there. They’re put about one and a half billion pounds into Scotland, uh, that is not going so well. So, so they’re talking about 3000 jobs, 1.5 billion in investment and then. Building, uh, offshore turbines for Britain and the larger Europe, but the UK government is hesitating and they have not approved it yet. And Scotland’s kind of caught in the middle. Ming Yang is supposedly looking elsewhere that they’re tired of waiting and figure they can probably get another factory somewhere in Europe. I don’t think this is gonna end well. Everyone. I think Bing Yang is obviously being pushed by the Chinese, uh, government to, to explore Scotland and try to get into Scotland and the Scottish government and leaders in the Scottish government have been meeting with, uh, [00:02:00] Chinese officials for a year or two. From what I can tell, if this doesn’t end with the factory in Scotland. Is China gonna take it out on the uk? And are they gonna build, is is me gonna be able to build a factory in Europe? Europe at the minute is looking into the Chinese investments into their wind turbine infrastructure in, in terms of basically tax support and, and funding and grants of that, uh, uh, aspect to, to see if China is undercutting prices artificially. Uh, which I think the answer is gonna be. Yes. So where does this go? It seems like a real impasse. At a moment when the UK in particular, and Europe, uh, the greater Europe are talking about more than a hundred gigawatts of offshore wind,  Yolanda Padron: I mean, just with the, the business that you mentioned that’s coming into to the uk, right? Will they have without Min Yang the ability to, to reach their goals?  Allen Hall: So you have the Siemens [00:03:00] factory in hall. They have a Vestus factory in Hollow White on the sort of the bottom of the country. Right. Then Vestus has had a facility there for a long time and the UK just threw about 20 million pounds into reopening the onshore blade portion of that factory ’cause it had been mothballed several months ago. It does seem like maybe there’s an alternative plan within the UK to stand up its own blade manufacturing and turbine manufacturing facilities, uh, to do a lot of things in country. Who I don’t think we know. Is it Siemens? Is it ge? Is it Vestus or is it something completely British? Maybe all the above. Rosemary. You know, being inside of a Blade factory for a long time with lm, it’s pretty hard to stand up a Blade factory quickly. How many years would it take you if you wanted to start today? Before you would actually produce a a hundred meter long offshore blade,  Rosemary Barnes: I reckon you could do it in a year if you had like real, real strong motivation [00:04:00] Allen Hall: really. Rosemary Barnes: I think so. I mean, it’s a big shed and like, it, it would be, most of the delays would be like regulatory and, you know, hiring, getting enough people hired and trained and that sort of thing. But, um, if you had good. Support from the, the government and not too much red tape to deal with. Then, uh, you know, if you’ve got lots of manufacturing capability elsewhere, then you can move people. Like usually when, um, when I worked at LM there were a few new factories opened while I was working there, and I’m sure that they took longer than, than a year in terms of like when it was first thought of. But, um, you know, once the decision was made, I, I actually dunno how long, how long it took. So it is a guess, but it didn’t, it didn’t take. As long as you would think it wasn’t. It wasn’t years and years, that’s for sure. Um, and what they would do is they don’t, you know, hire a whole new workforce and train them up right from the start. And then once they’re ready to go, then they start operating. What they’ll do to start with is they’ve got, you know, like a bunch [00:05:00] of really good people from the global factories, like all around, um, who will go, um, you know, from all roles. And I’m not talking just management at all, like it will include technicians, um, you know, every, every role in the factory, they’ll get people from another factory to go over. And, um, you know, they do some of the work. They’re training up local people so you know, there’s more of a gradual handover. And also so that you know, the best practices, um, get spread from factory to factory and make a good global culture. ’cause obviously like you’ve got the same design everywhere. You want the same quality coming out everywhere. Um, there is, as much as you try and document everything should be documented in work instructions. That should make it, you know, impossible to do things wrong. However, you never quite get to that standard and, um. There is a lot, a lot to be said for just the know-how and the culture of the people doing the um, yeah, doing the work.  Allen Hall: So the infrastructure would take about a year to build, but the people would have to come from the broader Europe then at [00:06:00] least temporarily.  Rosemary Barnes: That, that would be the fastest and safest way to do it. Like if it’s a brand new company that has never made a wind turbine before and someone just got a few, you know, I don’t know, a billion dollars, and um, said, let’s start a wind turbine factory, then I think it’s gonna be a few years and there’s gonna be some learning curve before it starts making blades fast enough. And. With the correct quality. Um, yeah. But if you’re just talking about one more factory from a company that already has half a dozen or a dozen wind turbine blade factories elsewhere in the world, then that’s where I think it can be done fast.  Allen Hall: This, uh, type of situation actually pops up a lot in aerospace, uh, power plants, engines. The jet engines on a lot of aircraft are kind of a combined effort from. Big multinational companies. So if they want to build something in country, they’ll hook up with a GE or a, a Honeywell or somebody who makes Jet engines and they’ll create this division and they’ll [00:07:00] stand this, this, uh, plant up. Maybe it’s gonna be something like that where GB energy is in the middle, uh, providing the funding and some of the resources, but they bring in another company, like a Siemens, like a Vestas, like a GE or a Nordex even to come in and to. Do the operational aspects and maybe some of the training pieces. But, uh, there’s a, there’s a funding arm and a technical arm, and they create a standalone, uh, British company to go manufacture towers to go manufacture in the cells to manufacture blades. Is that where you think this goes?  Rosemary Barnes: It depends also what kind of, um, component you’re talking about. Like if you’re talking about, I, I was talking a specific example of wind turbine blades, which are a mediumly complex thing to make, I would say, um. Yeah. And then if you go on the simpler side, when turbine towers, most countries would have the. Rough expertise needed, um, to, to do that. Nearly all towers at the moment come out of [00:08:00] China, um, or out of Asia. And with China being the, the vast bulk of those. Um, and it’s because they’ve got, aside from having very, very cheap steel, um, they also have just got huge factories that are set up with assembly lines so that, you know, there’s not very much moving of things back and forth. So they have the exact right bit of equipment to do. The exact right kind of, you know, like rolling and welding and they’re not moving tower sections around a lot. That makes it really hard for, um, for other countries to compete. But it’s not because they couldn’t make towers, it’s because they would struggle to make them cheap enough. Um, so yeah, if you set up a factory, you know, say you set up a wind turbine, um, factory in, uh, wind turbine tower factory in Australia, you, you could buy the equipment that you needed for, you know, a few hundred million dollars and, um. You could make it, but unless you have enough orders to keep that factory busy, you know, with the, the v

You know what they say about records? They’re made to be broken. Well, off the coast of the Virginian Province in China, a new machine is spinning China three. Gorges and Goldwin have connected the world’s first 20 megawatt offshore wind turbine to the electrical grid. 20 megawatts from a single turbine. It’s blade stretched 147 meters long. That’s nearly 500 feet. The rotor sweeps an area equal to about 10 football fields. The hub sits 174 meters above the waves, a 58 story building floating its sea. This one wind [00:01:00] turbine will power 44,000 homes. And here’s what makes it interesting. This is the same wind farm where the world’s first 16 megawatt turbine went in. That record lasted barely two years. Meanwhile, Chinese turbine exports hit a record, 8 million kilowatts in 2025, a 50% from the year before. Chinese companies now operate in more than 60 countries. Uh. Across the Atlantic, a different kind of milestone. Nova Scotia has quietly become Canada’s leader in corporate clean energy deals while Alberta fumbled through policy moratoriums, the maritime province signed agreements that drew renewable investment northward The $60 billion Wind West project aims to unlock 62 gigawatts of offshore capacity. That’s a quarter of Canada’s total energy needs. Premier, Tim Houston traveled to New York this past month for the [00:02:00] International Partnering Forum. He signed a deal with Massachusetts to collaborate on offshore wind development . Lisa Engler from the Massachusetts Clean Energy Center put it simply worked together lower costs, build the Atlantic Wind Industry. Nova Scotia’s first offshore lease auction comes later this year. And in Scotland, great British energy, announced its permanent headquarters. Location. Marshall Square. In Aberdeen, CEO, Dan McGrail called Aberdeen the perfect home for Britain’s publicly owned energy company. Thousands of engineers and technicians already call the city home Energy Minister Michael Shanks noted that Aberdeen has powered Britain for decades. First with oil and gas. Now with clean energy and on the American Prairie, South Dakota, regulators approved the state’s largest wind farm. Philip Wind Partners, a subsidiary of Chicago based Invenergy will build [00:03:00] 87 turbines across 110 square miles of private land north of Phillip. The price tag $750 million. The capacity. 333 megawatts enough to power hundreds of thousands of homes and in laboratories across Europe. Researchers announced a breakthrough that could solve when energy’s most stubborn problem. What happens when turbine blades were out The Oleum project has produced the first bal salt fiber reinforced vier composite laminate through a new infusion technique in plain English. Its recyclable blades made from volcanic rock fiber. The goal blades that last 20% longer repair 40% faster and costs 15% less over the lifetime. So there you have it from China’s colossal machines to Nova Scotia’s Bold Ambitions from [00:04:00] Aberdeen’s new energy company to South Dakota’s Prairie Wind Farm from European laboratories working on the recycling puzzle. The wind industry just keeps moving forward, and that’s a state of the wind industry on the 16th of February. 2026. Join us tomorrow for the Uptime Wind Energy Podcast.

Allen Hall: Will welcome back to the program.  Will Howell: Thanks so much for having me guys. Nice to see you.  Allen Hall: So Edinborough is the home of Armor Edge.  Will Howell: Yes, indeed.  Allen Hall: Yeah. And we went to visit your facility a couple of days ago. Really impressive. There’s a lot going on there. Will Howell: Absolutely. Absolutely. Yeah. So the, we’ve been in the facility for, um, a couple of years now, and it’s really just all part of our expansion as we continue to. To, uh, grow as a business?  Allen Hall: Uh, well the thing that struck me first was efficiency. If you’re gonna be in wind, do you need to be efficient?  Will Howell: Yeah,  Allen Hall: exactly. You have  Will Howell: to  be,  Will Howell: look, we know that we are a, a relatively small team, but we’re, we are, we are very reactive and we are gonna be always responding to the, the requests. The, the market drive for us internationally now is where we are really focusing. And even though we’ve got our small base from there, we’re exporting internationally around the world. And so. Yeah, I’m, I’m, I’m glad you guys came by and kind of saw what we’re up to.  Joel Saxum: If we could ask one thing, this is what we would ask. Turn up the heat. Turn down the wind. Turn off the rain.  Will Howell: Yeah, I’m [00:01:00] sorry about that. Yeah. Yeah, it’s, uh, there’s not much we can do about that at the moment.  Joel Saxum: Well, I’ll tell you what, if, if you’re talking leading Edge protection products, leading edge protection shield. Born from an area that’s rainy, that has heavy rain erosion, that understands,  Will Howell: we know, we know rain. We know rain. Yes. Look, we’ve been out in the North Sea now for over, over, over five years. These things are just being abused by Mother Nature out there and, you know, but we’ve, we are, we’re getting really good results consistently. Um, the products lasting really well against that, against that weather. And I think what’s interesting for us as well is it’s, it’s not just the Scottish rain and the ice and the snow. We’re, we’re getting good results out in the. The planes in the Midwest as well now. Yeah. And yeah, so yeah, very uh, universal products, we hope,  Joel Saxum: I mean, so this is one of the things we always talk about. When you talk wind turbine blades and you listen to the manufacturers, a lot of them sit in Denmark where the problem is mist in the air, it is rain, it is droplet size. It’s all the conversation you hear. But where we [00:02:00] see wind is dust, bugs, those kind of things. Like, it’s, it’s different stuff, right? So like I’m, I live in Texas. One of the things that’s beautiful about my home in Austin is when I look to the west in the, at, in the evening, it’s bright red skies all the time. Well, that means there’s dust in the air.  Will Howell: Yeah.  Joel Saxum: Right. And that’s, and when I look west, what am I looking at? 23,000 turbines out in West Texas. Right. So everything out there is getting beat up where we look at, um, inspections of turbines and we see turbines that are 1, 2, 3 years old that look like they’ve been in operation for 15 years. Will Howell: Yeah. Yeah.  Joel Saxum: There’s nothing left of them.  Will Howell: I know. And. You know, people use analogies like, oh, it looks like it’s been sand sandblasted. But it it has, it has, it is sandblasted, you know, we’ve, we’ve now conducted testing where we have literally taken kind of aerospace level testing and blasted sand at these shields, and they’re super resilient. But it has to be that universal products of resisting the water droplet that the mist, that side [00:03:00] of the, of the erosion problem, but also the particulate matter in the air. And there’ve been some of the. Places that we’ve installed. There was actually one site where they had a local, um, open cast mining nearby, and there was like marble particulate matter in the air. And these machines were getting trash in a couple couple of seasons. And again, we’ve been on there now for, I think now is our third year in that particular site. And again, really good results.  Joel Saxum: Well, I think, um, I mean, we did take some B roll when we were at your facility. And again, thanks for welcoming Sam. We love doing those. It’s, uh, but you showed us your installation methodology, and maybe we’ll show some of that with our producer Claire on mm-hmm. On this video. Uh, but the, the way you guys design your installation methodology to be simple and robust, easy for the technicians to make sure they can’t get it wrong in the field because they got enough other things to worry about. Will Howell: Uh, you know, I think, I think that’s been a big part of our, of our kind of design ethos since the, since the early days in the, in the r and d phase, it wasn’t only finding a robust material for the LEP Shields, a robust. [00:04:00]Adhesive to bond them on, but it’s the, it’s the kind of higher level. How do you actually get that onto a blade in the field by a rope or standing in a platform up in the, up in the winds And so, yeah, understanding what the technicians are having to go through in order to install this stuff. And that then feeds into your quality. ’cause you can have the best lab results in the world from your perfect installation sitting in a factory somewhere. But actually it’s the guys on ropes that are doing the, doing the hard work out there.  Joel Saxum: We see that all the time with our, like with our lightning protection products like. People, can you give us this lab test? Like we can, we’ll stack you up with lab tests. Mm-hmm. But what we really wanna show you is the test from the field.  Will Howell: Yeah, yeah, yeah.  Joel Saxum: The test that where it’s been sitting, soaking, getting hit by lightning. Mm-hmm. All of these things for years and years and years. Yeah. That’s the results we wanna show you. ’cause those are real.  Will Howell: Absolutely. Yeah, yeah, yeah. Makes  Allen Hall: the demo you gave us to install the shields and it’s basically a series of shields that go along the leading edge of the blade, sort of two parts of that one. Obviously you’re trying to recover the lost power, the a EP, that’s, that tends to be the big thing, [00:05:00] except in some locations, like Joel’s pointed out, it’s not that the leading edge is just kind of lightly beat up. It’s really beat up.  Will Howell: Yeah. Yeah.  Allen Hall: And you’re trying to prevent that from happening or to just to provide some protection, uh, if you’re just sort of category three, and I, I wanna walk through that for a minute because the demo you did was really interesting and I. It, it made sense once you watch the process happen. Mm-hmm. It’s really clear, but you’re able to take sort of cat three damage on the leading edge and not have to go back and do a lot of repair to it, which is where the vast majority of the funds are used to sort of get the blade to a point you can apply leading product. Oh yeah. Yeah. With Armor Edge, you don’t really need to do that. Will Howell: Yeah. And I think that that that really comes into the. Into the value proposition of the, of the whole, of the whole process. If the labor costs and the downtime of the machines, there’s so much value in that. And so if you can reduce the repair time or just remove it completely, because you can install [00:06:00] directly on top of existing erosion, you’ve really saved some significant cost out of the, out of the job. And that’s really only just by function of the design of the shields. We are a, a semi rigid polymer material, so we don’t conform to the existing erosion that’s on the surface. So. Yes. If you, if you have a cap four or five and you have some structural glass repair that needs to happen to maintain the integrity of the blades, you still need to complete that repair. You don’t need to go any further. So if you’ve only got a one, two, or three, you’re talking the fillers, the putties on, on the surface. You don’t need to, to replace those. Just apply our high build adhesive, get the shield on top, and you’re finished.  Allen Hall: And so you start at the tip with a, a tip. Shield and then you work your way, kind of Lego wise up up the leading edge of the blade. Yeah,  Will Howell: yeah, yeah.  Allen Hall: It’s really straightforward and, and the, the system you’re using, the adhesives you’re using, and the techniques are really adapted for the technician. What I watched you do, I’m like, oh, wow, this is really [00:07:00] slick because there’s been a lot of thought going into this. You have done this. Hundreds of times yourself before you’ve shipped it out to  Will Howell: the world. Yeah, exactly. And, and that was, that was a big part of the, part of the r and d process is to, again, as I said, it’s, it’s not just affecting these applications in a lab envir

And now your hosts.  Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host Alan Hall, and I’m here with Rosemary Barnes, Yolanda Padron. Matthew Stead down in Australia. So welcome Matthew.  Matthew Stead: Great to be here. Thank you, Alan.  Allen Hall: We have a number of articles and interesting topics this week. Top of the list is Vestus. Vestus announced their Q4 numbers, and although the the revenue is great, uh, they, they had a profit of about 580 million euros. It was below what analysts expected, so the shares dropped about 6% on the news. But the CEO of Vestus is saying, uh, full speed ahead. They’re, they’re willing to make some concessions. Vestus, as it sounds like, in terms [00:01:00] of thinning out the company a little bit, which I, that’s been a, a, a complaint from investors for a little while. But in, in terms of, uh, going forward in renewable energy, Vestus is still going to pursue that. The offshore wind business looks like it’s gonna be profitable in 2027. And as we all know, and we, we see wind turbine prices, uh, quite a bit in each of our positions. Vestas is the most expensive one on the block, but they’re still winning a whole bunch of orders. And, and Matthew, uh, Vestas globally. I would say is the leader right now, if you look at Siemens GAA and GE Vestas is really winning a lot of the orders. Matthew Stead: Yeah, I think a very strong reputation for quality. Um, I have to say, I’ve got some Vestas turbines behind me, so, um, all paid for by myself. They’ve always been well regarded for their, um, you know, quality of [00:02:00] product. And when I first got into wind, um, you know, probably 15 years ago, you know, they were, they were the leaders at that point in time. And so, you know, quality. Reduces future o and m cost. I think  Rosemary Barnes: it’s not just about like the simple o and m, either it’s the risk that something really bad goes wrong and you’re just stuck with, you know, like a, a whole a hundred turbines that can’t be fixed or, you know, at least a large, a large chunk of them. The more that I work in, in o and m, the more you see, like on occasion when you do have those serial issues that mean, you know, like. Sometimes all the blades in the wind farm have to be replaced or sometimes all the generators or you know, even if it’s not replaced, if you’ve gotta take them all out and do something and put ’em back in, it is just such a massive cost. And, um, reducing the chance that that’s gonna happen is actually really valuable for insurance. And yeah, all sorts of other financial reasons.  Yolanda Padron: And even as an FSA customer, I feel like Vestus has a lot more transparency as to what actually is going on, [00:03:00] on site and more able to, to collaborate on, on like a site to site basis, which is very obviously helping them in getting a lot of return customers. Allen Hall: Yeah. One of the key revenues for Vestus has been the FSA, where almost every project I’ve seen over the last couple of years has had a 2030 year FSA attached to it. Rarely do you see. Order without that, and that’s a long-term revenue stream. The, the thing about Vestus and the complaints that are happening, uh, around vestus are odd because if you look at Siemens Cab Mesa, they’re really struggling to be profitable. And then GE Renova, which is really, really struggling to be profitable and they’re losing several hundred millions of dollars a year. Vestas is bringing in a profit, and, and yet the investors are wanting even more. I, I guess, is, is this just a relationship to the. Where you can invest money today. The stock market going up so high, gold and silver prices are at record highs. Rosemary Barnes: Haven’t they just [00:04:00] crushed?  Allen Hall: They have a little bit. They’ve, they’ve rescinded some, but they’re still at really high numbers, right? So Gold Cross, what? $5,000 and ounce and then, uh, it was it 2000 a year ago? So the, the rise in the value of, of, uh, rear metals is crazy. Is there a plan you think Vestas is changing the way they’re gonna operate? ’cause uh, they’re talking about thinning out the ranks and they do seem to be becoming more vertically integrated with the acquisition of the TPI factories down in Mexico. GPI in India  Rosemary Barnes: before we make it sound too much like a paid segment from investors, I have to say I disagree that they’re like just crushing it with the, the FSAs. I think that the full service agreements are across the board. Perform badly in Australia, at least I think it’s different elsewhere. Um, maybe it’s a good segue into, uh, talk about our event that we’ve got coming up to talk [00:05:00] about, um, the difficult operating conditions in Australia. But I, I think that best as, like everybody else has been surprised at how many things can go wrong in an Australia and wind farm. And, um, I don’t, I I would’ve put them up on a pedestal for. Particularly noteworthy, um, brilliant service with the FSAs. I think, yeah, across the board everyone’s doing a little bit less than they should be, and I have no doubt that they’re also making a whole lot less money on those agreements than what they spent or spending a lot more than what they’re expecting. So I don’t wanna be too harsh in my judgment.  Yolanda Padron: That’s fair. The bar is very low.  Rosemary Barnes: But what I do notice when I go to international events, um, and I, you know, I talk to, I’ve got a lot of ex-colleagues that’s still working in the industry and vest. Stands out as still investing a lot in r and d. And that doesn’t mean like crushing out a new platform every single year or every two years. It’s not that. But they are investing in a lot of new technologies that are more incremental. They’re [00:06:00] looking at bigger technology leaps and um, you know, still investigating stuff like that. Like I think if I was to go back working for an OEM, that’s the kind of work I’d like to do. And investors does seem like it’s the main company that’s still doing a whole lot of that. With the exception of, of the Chinese manufacturers, which are obviously doing like tons and tons of new development. But, um, I don’t have the insight into them like I do with the European ones.  Allen Hall: As you’re listening to this podcast, most of the people on this podcast are traveling to Melbourne, Australia for Woma 26. That’s Wind Energy and M Australia. Big event. Matthew, the numbers are impressive. I’m getting a little bit scared. Run out of food and uh, seats because there is a massive influx in the last 24, 48 hours, which is great to see, but wind energy in Australia. Is huge, and the o and m aspect is one of those key pain points. Matthew Stead: Yeah. I think, uh, thanks to Rosie and Alan, your argument, [00:07:00] um, a little while ago, your argument, which spurred the whole, um, the reason for the conference. Um, you know, the, the lack of, uh, Australian content, the lack of, um, poor. Conferences in Australia. I think unless you’d have that argument, um, this event wouldn’t, wouldn’t be there. Allen Hall: Rosie did bring up that she had been to a number of conferences and so had I that were pretty much useless in terms of take home. What could we be able to use in the world and, and make the world just slightly better from our knowledge and. With all the policy talk and uh, discussion about sort of global warming things that it’s not really useful necessarily in making your operations run more efficiently. And this was what Woma is all about is. Sharing information. Not everybody runs their operations the same. And you can learn from that of the way, uh, others do it. And at the same time, we’re bringing in experts from around the world to talk about some of [00:08:00] those really critical issues. One of them being leading edge erosion. And Rosie’s been doing a lot of work in Australia on leading edge erosion and the complexities around that. Rosie, the leading edge erosion discussion and the panel involved in the people are gonna be on the panel are impressive. What are you looking forward to?  Rosemary Barnes: I’m looking forward to, um, getting the international perspective because leading edge erosion, I mean, there’s heaps of aspects of wind turbine operation that I think are just dramatically different in Australia, but I think leading edge erosion is the one that like really, really jumped out at me. When I was, um, when I moved back to Australia and started looking at inspection reports for wind farms that were like one or two years old, and you see 90, 99% of turbines that have significant erosion like within a couple of years. It’s like, this is, this is not. Like, I’ve never, I’ve never seen this before. It’s clear that no one is designing these products that are gonna pee

    Vestas Sees Auctions Recover, Siemens Gamesa Spinoff Debate

    Allen covers Vestas CEO Henrik Andersen’s optimism on European auction reforms and bilateral CfDs, Australia’s Warradarge wind farm expansion paired with major grid upgrades, New Zealand’s wind-to-hydrogen project, South Korea’s Hanwha Ocean building a new installation vessel, and Siemens Energy’s debate over spinning off Gamesa.

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 Henrik Andersen has seen a lot of failed auctions. The Vestas chief executive watched subsidy-free tenders collapse in Germany… France… the Netherlands… even his home country of Denmark. Developers wouldn’t bid. The risk was too high. But this week… Andersen stood before investors with different news. The UK’s AR7 delivered eight point four gigawatts. A record. Eight projects approved… including two floaters. Denmark and eight North Sea nations committed to one hundred gigawatts. And Germany’s onshore auction pipeline… is finally moving. Andersen sent thanks directly to Ed Miliband… Britain’s Energy Minister. “Now it’s starting to work.” … The difference? Bilateral CfDs. After watching zero-subsidy models fail across Europe… governments returned to revenue stabilization. Strike prices developers can actually finance. Andersen believes the industry should learn from these auction designs… before repeating old mistakes. Steen Brødbæk at Semco Maritime agrees. Projects are maturing. Suppliers… can finally earn a living. … Vestas identified three priority markets in their annual report. Germany for onshore. North America. And Australia. The drivers? Energy security concerns. Data center load growth. And the AI electricity surge that every grid operator is scrambling to model. As for Chinese OEMs entering European tenders? Andersen would be surprised. “You should never be surprised by anything these days,” he said. “But in this case… I would actually be surprised.” … Down in Western Australia… Warradarge is proving his point about mature markets. Four of thirty additional turbines are now vertical. When the expansion completes… eighty-one machines will generate two hundred eighty-three megawatts. The state’s largest wind farm. Owned by Bright Energy Investments… a joint venture between Synergy and Potentia. One hundred twenty workers at peak construction. And critically… the state is building transmission to match. Clean Energy Link North… the largest grid upgrade in Western Australia in more than a decade… will unlock capacity in the South West Interconnected System. Generation AND grid… moving together. That’s how you hit a 2030 coal exit. … Meanwhile in Taranaki… New Zealand… Vestas secured a twenty-six megawatt order with a twenty-year service agreement. Hiringa Energy is integrating wind with green hydrogen production at scale… serving transport… industry… and agriculture. Turbine delivery begins Q1 this year. Commissioning… Q2 twenty-twenty-seven. One of New Zealand’s first large-scale wind-to-hydrogen projects. The electrolyzer economics are finally penciling. … But you can’t install offshore turbines without vessels. And South Korea just solved a bottleneck. Hanwha Ocean won a three hundred eighty-five million pound contract… to build a WTIV capable of fifteen-megawatt class installations. Korea’s first vessel at that scale. Delivery… early twenty-twenty-eight. Korea expects twenty-five gigawatts of offshore capacity by 2035. They’re not waiting for European vessel contractors. They’re building their own supply chain. Hanwha has now delivered four WTIVs globally. … Not everyone is celebrating. At Siemens Energy… activist investor Ananym Capital is pushing to spin off Siemens Gamesa. CEO Christian Bruch calls the idea reasonable. But timing matters. The wind division must stabilize first. Bruch believes offshore wind can follow the same recovery path as the grid business… which went from crisis… to profitability. Turnaround before transaction. … So, last week we had: CfDs reviving European auctions. Australia building generation AND transmission together. New Zealand coupling wind with hydrogen. Korea investing in installation vessel capacity. And Siemens… working to fix its turbine business before any restructuring. Different geographies. Same lesson. The projects that succeed… are the ones where policy… supply chain… and capital… finally align. … And that is the state of the wind industry for the 9th of February 2026. Join us tomorrow for the Uptime wind energy podcast.

    Morten Handberg Breaks Down Leading Edge Erosion

    Morten Handberg, Uptime’s blade whisperer, returns to the show to tackle leading edge erosion.

Energy’s brightest innovators. This is the Progress Powering Tomorrow. Allen Hall: Morten, welcome back to the program.  Morten Handberg: Thanks, Allen. It’s fantastic to be back on on, on the podcast. Really excited to, uh, record an episode on Erosion Today.  Allen Hall: Wow. Leading as erosion is such a huge worldwide issue and. Operators are having big problems with it right now. It does seem like there’s not a lot of information readily available to operators to understand the issue quite yet. Morten Handberg: Well, it, I mean, it’s something that we’ve been looking at for the, at least the past 10 years. We started looking at it when I was in in DONG or as it back in 2014. But we also saw it very early on because we were in offshore environment, much harsher. Uh, rain erosion conditions, and you were also starting to change the way that the, the, uh, the coatings [00:01:00]that were applied. So there was sort of a, there was several things at play that meant that we saw very early on, early on offshore.  Allen Hall: Well, let’s get to the basics of rain erosion and leading edge erosion. What is the physics behind it? What, what happens to the leading edges of these blades as rain? Impacts them.  Morten Handberg: Well, you should see it as um, millions of, of small fat, uh, small fatigue loads on the coating because each raindrop, it creates a small impact load on the blade. It creates a rail wave that sort of creates a. Uh, share, share loads out on, uh, into the coating that is then absorbed by the coating, by the filler and and so on. And the more absorbent that your substrate is, the longer survivability you, you’re leading into coating will have, uh, if you have manufacturing defects in the coating, that will accelerate the erosion. But it is a fatigue effect that is then accelerated or decelerate depending on, uh, local blade conditions.  Allen Hall: Yeah, what I’ve seen in the [00:02:00] field is the blades look great. Nothing. Nothing. You don’t see anything happening and then all of a sudden it’s like instantaneous, like a fatigue failure.  Morten Handberg: I mean, a lot of things is going on. Uh, actually you start out by, uh, by having it’s, they call, it’s called mass loss and it’s actually where the erosion is starting to change the material characteristics of the coating. And that is just the first step. So you don’t see that. You can measure it in a, um, in the laboratory setting, you can actually see that there is a changing in, in the coating condition. You just can’t see it yet. Then you start to get pitting, and that is these very, very, very small, almost microscopic chippings of the coating. They will then accelerate and then you start to actually see the first sign, which is like a slight, a braided surface. It’s like someone took a, a fine grain sandpaper across the surface of the plate, but you only see it on the leading edge. If it’s erosion, it’s only on the center of the leading edge. That’s very important. If you see it on the sides and further down, then it’s, it’s [00:03:00] something else. Uh, it’s not pure erosion, but then you see this fine grain. Then as that progresses, you see more and more and more chipping, more and more degradation across the, the leading edge of the blade. Worse in the tip of it, less so into the inner third of the blade, but it is a gradual process that you see over the leading edge. Finally, you’ll then start to see the, uh, the coating coming off and you’ll start to see exposed laminate. Um, and from there it can, it can accelerate or exposed filler or laminate. From there, it can accelerate because. Neither of those are actually designed to handle any kind of erosion.  Allen Hall: What are the critical variables in relation to leading edge erosion? Which variables seem to matter most? Is it raindrop size? Is it tip speed? What factors should we be looking for?  Morten Handberg: Tip speeds and rain intensity. Uh, obviously droplet size have an impact, but. But what is an operator you can actually see and monitor for is, well, you know, your tip speed of the blade that matters. Uh, but it is really the rain intensity. So if you have [00:04:00] sort of a, an average drizzle over the year, that’s a much better condition than if you have like, you know, showers in, in, in, in a, in a few hour sessions at certain points of time. Because then, then it becomes an aggressive erosion. It’s not, it’s, you don’t, you get much higher up on the. On the, on the fatigue curve, uh, then if it’s just an average baseline load over long periods of time,  Allen Hall: yeah, that fatigue curve really does matter. And today we’re looking at what generally is called VN curves, velocity versus number of impacts, and. The rain erosion facilities I’ve seen, I’ve been able to, to give some parameters to, uh, provide a baseline or a comparison between different kinds of coatings. Is is that the, the standard as everybody sees it today, the sort of the VN curve  Morten Handberg: that is what’s been developed by this scientific, uh, community, these VN curve, that that gives you some level of measure. I would still say, you know, from what we can do in a rain erosion tester to what is then actually going on [00:05:00] the field is still very two very, very, very different things you can say. If you can survive a thousand hours in a rain erosion tester, then it’s the similar in the field that doesn’t really work like that. But there are comparisons so you can do, you know, uh, a relationship study, uh, between them. And you can use the VN curves to determine the ERO erosion aggressiveness. Field. We did that in the bait defect forecasting that we did in wind pile up with DCU back in 2019, uh, where we actually looked at rain erosion across Europe. Uh, and then the, uh, the actual erosion propagation that we saw within these different sites, both for offshore and for onshore, where we actually mapped out, um, across Europe, you know, which areas will be the most erosion prone. And then utilize that to, to then mo then, then to determine what would be the red, the best maintenance strategy and also, uh, erosion, uh, LEP, uh, solution for that wind farm. Allen Hall: Oh, okay. Uh, is it raindrop size then, or just [00:06:00] quantity of raindrops? Obviously drizzle has smaller impact. There’s less mass there, but larger raindrops, more frequent rain.  Morten Handberg: If you have showers, it tends to be larger drops. Right. So, so they kind of follow each other. And if it’s more of a drizzle. It will be smaller raindrops. They typically follow each other. You know, if you’ve been outside in a rainstorm before we just showered, you would have sense that these are, these are much higher, you know, raindrop sizes. So, so there is typically an a relation between raindrop size and then showers versus a drizzle. It’s typically more fine, fine grain rain drops. Allen Hall: And what impact does dirt and debris mixed in with the rain, uh, affect leading edge erosion? I know a lot of, there’s a lot of concern. And farm fields and places where there’s a lot of plowing and turnover of the dirt that it, it, it does seem like there’s more leading edge erosion and I, I think there’s a little bit of an unknown about it, uh, just because they see leading edge [00:07:00]erosion close to these areas where there’s a lot of tilling going on. Is it just dirt impact worth a blade or is it a combination of dirt plus rain and, and those two come combining together to make a worse case. Uh, damage scenario.  Morten Handberg: Technically it would be slightly worse than if it were, if there is some soil or, or sand, or sand contamination in the raindrops. But I mean, logically rain typically, you know, comes down from the sky. It doesn’t, you know, it doesn’t mix in with the dirt then, you know, it would be more if you have dirt on the blades. It’s typically during a dry season where it would get mixed up and then blown onto the blades. Honestly, I don’t think that that is really what’s having an impact, because having contamination in the blade is not something that is, that would drive erosion. I think that that is, I think that is, that is a misunderstanding. We do see sand, sand erosion in some part of the world where you have massive, uh, sand, uh, how do you say, sandstorms [00:08:00] coming through and, and that actually creates an, an abrasive wear on the plate. It looks different from rain erosion because it’s two different mechanisms. Uh, where the sand is actually like a sandpaper just blowing across the surface, so you can see that. Whereas rain is more of this fatigue effect. So I think in the, theoretically if you had soil mixed in with rain, yes that could have an impact because you would have an a, a hardened particle. But I do, I don’t think it’s what’s driving erosion, to be honest. Allen Hall: Okay, so then there’s really two different kinds of failure modes. A particle erosion, which is more of an abrasive erosion, which I would a
