Allen Hall: Welcome to the special edition of the Uptime Wind Energy podcast. I’m your host, Allen Hall, and I’m here with my co host, Joel Saxum. We’re still in San Diego at ACP OM& S, and we have run into a bunch of new technology while we’ve been at the show, and one of them is UV cured resin systems, because when it’s cold outside, You really can’t use standard epoxies and it’s cold in most of America and the world right now.

Yeah. So all repair businesses essentially shut down until it gets to about 50 degrees Fahrenheit which could be a while, particularly in the Northern latitudes. So we run into Marvin Hirdler with Bergolin and Bergolin has a new product in the UV space and also Michelle Bonnett with FibreGlast.

And I have worked with, I’ve purchased some FibreGlast material, UV care material. And it’s really awesome, actually for some projects that we were working on. This, I really want to just touch on the UV space because there hasn’t been a lot of UV resin applications in wind. We had touched From aerospace background.

We have used it there but in the wind world, we haven’t, which is crazy because we our season is so short, the repair season’s crazy. Sure. And you’re up tower and yeah, tower and access is tough. It’s really hard. But these new UV resin systems are magical. It’s crazy good. And as, as a, as someone who’s tried it, it’s amazing.

It’s amazing, and I’m surprised we haven’t done this years earlier, but it’s, it’s finally coming to market. I want to talk about this, the one I use first, which is the FibreGlast repair patch. So Michelle, maybe you can introduce yourself a little bit, but you guys, FibreGlast is based in Ohio, right?

So you’re a U. S. based company, and FibreGlast does all kinds of things, fiber related, resin related, you’re like a resource.

Michelle Bonnett: Yes. Correct. Where we’ve been in business for about 65 years where our website is fibreglast.com. We sell to a guy in his garage doing a small repair to a lot of large companies in the aerospace automotive.

And of course wind. We Work predominantly with small quantities. We ship them very fast. If you order before two 30 Eastern time, they ship same day. So it is imperative in the wind industry to get those products out quick. We teamed up with a company called SunRes that has been an industry leader in UV for about correct me if I’m wrong, but around 30 years.

And recently got GE approved UV prepreg. So it’s a 300 by 700 millimeter patch. It comes in UD1000, Biax 806, and the Combi 900. It is a vinyl ester resin. That is cured UV. You can typically lay up about 10 layers. Very easy patches that you can build very quickly, get it up to the blade and apply.

Joel Saxum: One of the things I want to touch on that you said there, and this is super important for the space, right? Anybody that’s an ISP, blade repair, that’s listing, or an asset owner, is that it is GE approved. Yes. Because I know we were at Blades USA, and we were all talking through some of these new UV cured systems, and that was some of the ISP saying this is great.

We can take A project that normally would take us six hours to let some cure and do some layering. Now it takes us ten minutes. That’s a game changer for everybody, right? And in different weather conditions, which is even better. But, is it approved? Can we use it on specific blades? Will the OEM still, honor warranties or things like this?

That was one of some of the big questions. And to say that product is GE says, yes, good to go. That’s huge. That’s not just social proof. That’s technical proof. We can use these products in the field and trust them.

Michelle Bonnett: Correct. And we do carry a non hazardous. It’s an accolade, a modified accolade epoxy.

In these 12 by 12 patches, chopstrap mat and the combi 900 as well. Those are currently with G. E. And testing to get that non hazardous approved. Yeah, FibreGlast is really good. We’re all hazard trained. ship dangerous goods, we overnight stuff when needed. And so these hazardous patches can be shipped for an expense.

The non hazardous is a game changer because it takes that money away and lets us ship overnight without any additional costs. It is with currently with GE, they are testing to make sure, but you really won’t see any type of difference in strength properties all of that. So it should be.

As quick as GE can get approved fairly quickly. So that’s one of the things that we’re working on, but we do carry the 12 by 12 patches as well as those approved hazardous 300 millimeter by 700 millimeter patch.

Allen Hall: And that, that, that patch you buy, since I purchased this thing, it comes in a sort of four line pouch that it’s all ready to go.

You open the pouch, you slide the patch out, you apply it to the Turbine blade, roll it in, kick it off if you need to. It has a plastic, a clear plastic coating on it, so it hardens on the surface. That’s one of the things that everybody, I think, needs to know, right? Is that you, there is a plastic coating over top of the material, so that it doesn’t oxidize and remain sticky.

It’ll cure out all the way perfectly, which is really simple to use. I, even, electrical engineer me, was able to do it. But it is one of those things it’s a little bit different than maybe a standard epoxy. But It’s really simple. If I had to do a quick repair out somewhere in January or February on a wind turbine, that’s what I’m using, because I can do it.

Michelle Bonnett: And that the hazardous material comes with and everything’s color coded. So you have a black plastic lining that you would initially take off to put on the blade followed by a P. E. T. Clear that remains on there because it is a vinyl Lester. So it does need that airless skin, airless finish.

And then it has an orange an orange material that is UV blocking. So what that allows you to do is apply however long it takes you to apply. Then you remove that orange film and bam, that’s when the sun hits. Now, we really recommend the L. E. D. U. V. Lamps. Even out in the field where the sun is present when you’ve got sun out and that what that does is it just, it cures a little quicker.

So we’re talking instead of five to 10 minutes, you’re talking three to five minutes. But it also gives you that consistency. You can make sure that it’s cure. Sometimes if the sun doesn’t quite hit or you get a cloud or something like that might happen, you might not get consistent UV. And so that lamp is important.

Joel Saxum: So let me ask you about that lamp. Now I’m just like from an operational perspective, right? If people are on ropes or in a, in a basket or something, that’s a different story. But what are this, what size is this? What are those? Are they? No, the lamp itself. Oh, the lamp itself, I don’t know why they got to work with that tower.

It’s about 10 by, I think 10 by 12, it’s, it is fairly small.

Michelle Bonnett: You hold it about 13 feet from from the The cure itself. Thirteen feet? Oh, sorry, thirteen inches. Oh, I was like, how are you going to do that? Thirteen feet! You’ve got some really long arms. What I love about it is it has very different mounting capabilities.

So you can either strap it to hold it does have some handles that you can use. Okay. There’s just different ways and different methods that you can use to strap it onto something or secure it to someplace.

Joel Saxum: So if you’re on ropes, it’s not too bad to just take it with you.

Michelle Bonnett: Correct. Yeah, it would hang off of a, a belt.

It’s really lightweight.

Allen Hall: Okay, perfect. So the magic to this is that the UV light is triggering a chemical reaction. It’s breaking some bonds or triggering some bonds so that it starts to, the material warms up itself, it self heats and self cures, so it’s like having a heat gun without having a heat gun.

Using a lamp to trigger the heat in material, and boom, it cures out. It’s magical. Yeah, let’s find a watch and play with.

Joel Saxum: Yeah, and that’s the game changing is right something like we said earlier That would be six to eight hours between layers between top coat and all these different things now Ten minutes because it’s cured hard.

Michelle Bonnett: The best part about it is humidity levels Temperature none of that is important It just takes that out completely.

We had done some testing when we first started carrying this material and we were in 30 degrees, just sat it out on a picnic table, five minutes, it was cured, completely cured. 30 Fahrenheit, right? Yeah, 30 Fahrenheit.

Allen Hall: So in the, let’s, I want to touch on this just for a brief moment. When we say hazardous and non hazardous, what we’re saying is polyester hazardous.

It’s the odor of the thing. It has a certain odor to it. If you’ve been around polyester and the standard. Non hazardous, which is epoxy, has really no smell to it. No smell to it at all.

Michelle Bonnett: Yeah, a lot of the demos that we’ve been doing at some of the different shows are very much inside a hotel and you just can’t have, yeah, you just can’t have that vinylester, polyester, the styrene smell that everybody’s aware of.

Joel Saxum: Right from the booth every once in a while, we’re there and we go, oh, wow, what is that? They cured it and they’re hitting it with a hammer. Yeah, whacking it with a hammer.

Allen Hall: Yeah, it’s amazing material. And I want to start talking about the burgundy material because this is something new too. Yeah. And Bergolin is based out of what country?

Marvin Hirdler: Germany. Based in Germany. We’re working in WIND over 20 years already. Yes. We are from the coding side. We started with J codes, fillers, top codes, LEP systems. Yep. In the manufacturing side, for sure. And then, I would say three to five years ago, we started also going into blade repair business.

Yeah. Because, yeah, the OEMs are asking for it. We need a different solution. Same application or different application methods has to be faster, easier to apply, robust access, platform, whatever you have. So this was the reason we started going into the blade repair. And last year or one and a half years ago, we started thinking about UV materials.

So we started manufacturing not only, but also developing a UV filler first. So this was the first material we launched into the market not only for blade repair, but also for other composite repairs.

Allen Hall: Okay, so avoid leading edge damage or something to fill in the little bumps and the bruises.

Okay.

Marvin Hirdler: And yeah, especially the good thing with the UV material is always you have a single part material. You don’t have to mix anymore. You don’t have to. True. Yeah. The chrome wife goes away and all the mixing goes away.

Allen Hall: The mixing nozzles and all the craziness involved with that. Yeah.

You’ve seen errors. You just gotta keep it. There’s so many errors with the mixing nozzle. Just keep it dark. Make sure the sun doesn’t get in there. But it’s not that sensitive to light. The Birkeland material is very narrow frequency, light frequency, to make it trigger.

Marvin Hirdler: Exactly. So we have found a way to integrate a UV blocker inside the material.

So if you apply this material, the filler and the resin too, it’s the same chemistry in the sun directly, it will not cure without the curing lamp. So you can do it in the sun. Depending on the UV index, you will have an amount of time. So with a filler, for example, when we have a very high UV index, we tested it here in Texas last year.

UV index 9, 100 degrees Fahrenheit. And you still have three minutes to apply the filler, probably in the sun. Wow. Okay, and then you put the uv lamp on top and then it starts curing.

Allen Hall: Okay, so in the other piece to the burglar material, which is called i’m going to get this right Burgle lead.

Yeah for led Bergl is it BergoLED? Yeah, it’s BergoLED. Yeah, you can BergoLED Okay. All right. So it’s a speed resin I think is how we would say in america speed resin. That’s what’s going to stick is it’s it has a color to it So we apply the resin so you have dry fabric from FibreGlast and you’re applying the resin to It’s red or a pinkish color.

Yeah. Yeah, so the UV light when you kick it off turns it clear So exactly what are you doing? I think this is the problem that everybody’s worried about when I do 5, 8, 10 layers of repair. How do I know I got the UV down to that last layer? With the tinting part of it, that eliminates that as a question.

Yeah. It just changes colors.

Marvin Hirdler: Especially when we’re doing it in blade repair, we were not aware how easy it would be to test if all the layers cured through. It’s easy testing with epoxy, you go ahead, the curve of the temperature and everything. You don’t have that with the UV material.

It’s not getting hot or whatever. So we found a way. This is yeah, an initiator from a different industry and we use it normally for floor coatings. Because they doing the same thing with the UV stuff and it’s first blue or red and then they see if it’s cured or not It’s colorless afterwards.

Okay, so we use the same thing this is cool.

Joel Saxum: Okay, it’s So they make this product for like at Home Depot. You can buy it not the same product no, same concept. It’s a like putty You’d fill nail holes within the wall, right? And when you put it on it’s pink and when it dries better It drives white.

Oh. It’s just, it’s, but it’s genius. I always buy it when I need it because I want to know when the job is done. Exactly. And then you see all these little pink dots all over the place and in 10 minutes they all turn white and you’re like, all right, we’re good here. We can paint over it. Oh, okay. It’s slick.

Slick as hell.

Marvin Hirdler: Yeah, just make it easier, especially for the text to see directly in visual if it’s cured or not. So this is something we figure out. It’s the same with the putty or the putty too. So we have also the same idea. First red, then colorless after curing. So just make sure you can do a repair, the whole repair with just visual looking, okay, it’s cured or not.

Joel Saxum: I think that there’s something important here to touch on. So cost of poor quality, COPQ as it’s called in business, is a huge thing in the wind industry because The engineers are not on the blades and they’re the ones that have to look at the repairs to make sure they’re well done. Your blade text, that’s the front line.

That’s the people you have to trust. But what happens of course in the world as people who listen, know this, you’re in the field, you’re taking pictures, putting together repair reports, all this stuff, and then that gets sent to the back office or sent to the client. They have to approve it. And, or you may have to come back up.

Sometimes it’s live where they’re taking pictures right now and someone’s looking at them remotely to make sure the repair is done properly. And what you guys are doing is engineering a, now a product. Of that process, you’re dummy proofing it. Yeah. This is the idea, right? It was red, it’s clear now.

Yeah, you are good to go. There’s no approval needed. Is.

Allen Hall: Just think about it, all the porcelain. Yes, I know. The temperature outside, the humidity outside, and all of that. And then, obviously, bring water or something to cure out before they start playing the top coat to it.

Joel Saxum: Yeah, I mean, it’s the solution that you’re putting forth for solutions.

Is part of the solution for scaling the wind technician fleet of people?

Allen Hall: Yeah, we need to extend our window. The technicians are essentially sitting on the sidelines for six months out of a year. Yeah, that’s crazy. We need to put the guys back to work and to start fixing blades because, and especially at this conference where you walk through the halls here and start talking operators, everybody, cause it’s February, everybody’s got huge blade issues.

They got a lot of blades. Can they even get them all done this year? The season’s short. They’re trying to schedule people’s, not enough technicians. If you just double the amount of time you have to go and do some of these things makes life a lot easier.

Joel Saxum: And you’re cutting down on the time on Blade and on project.

Yeah, too. Yeah. That’s the big, speeding it up quite a bit. Yeah. Yeah. Because now a team of a rope access team with two people on it, and instead of, fixing one turbine per week, they can now maybe fix three. Sure. That’s huge. Yep. Yep. It’s the speed.

Marvin Hirdler: We talked about that. Especially when we talk about like the.

Countries North Canada or also the North US states. So they had the biggest issue especially in winter doing no repair at all And yeah, just certain so we’re talking about turbines who is just standing still not producing any energy so this is the reason we’re trying to get in contact most of the time Starting with operators owners because they have to pay for it Sure, and they have to pay or not getting paid for downtime So they’re trying to make it fast Even if it’s just in the beginning a temporary repair with the uv materials because they say okay We want to test that first Seeing the same repair in six, eight months later in the summer, everything is good.

But so they can start use the turbine again in operation. So they don’t have the downtime at all. And now they just have to wait until the temperature is high enough. Humidity is low enough, whatever they have limitations on.

Joel Saxum: Yeah. That’s something that you see quite often in the industry is Hey, we’ve got a damage.

We need to patch this thing just to get it through the winter. Because if you get ice, snow, water, anything in there, and then your core gets wet, then you end up running into real big problems. So now you have a solution where you can go into a temporary repair. It’s technically permanent, but yeah, but you could go up there and you can slap one of those panels on UV cure, move on to the next one before wet weather changes.

Allen Hall: It’s genius. Yeah, it really is. And I know when I first saw FibreGlast website, like, why haven’t I seen this before? And we just released it. So you had a good, you had a good reason for it because you just brought it out. But I was probably one of the early people to see it and try to try it. So it’s amazing.

And I if I’m an operator trying, want to try this material, cause they don’t want to try it, they want to check in or independent service provider, they want to play with the material before they take it out in the field. What do they need to do? Who are they calling? Are they calling FibreGlast here?

Are they calling Michelle and saying, hey, give me a sample, send me a sample? Exactly. And what should they be asking for? They should be asking for polyester, the polyester material for GE turbines, the epoxy for Vestas. What’s the scenario here?

Michelle Bonnett: Right now, probably the hazardous is the most popular.

Okay. But. Any of them, like I said the strength properties, all of the properties are almost identical to the data sheet there. You can download on the website. We have our, the product data sheet and the SDS available. For you to take a look decide what you want. Our business development manager, his name is Rod Miaty.

He’s over at our, he’s manning the booth while we’re over here. Yeah. He’s the guy to get in touch with. Yes. Rod Miaty. Yeah. Rod Miaty.

He is the, probably the best person or call up customer service. They’ll be happy to process one for you. Okay. The best part about these things is we I, if you buy direct from Sunrise, you’re buying boxes of this stuff.

We do like to downsize. So our 12 by 12 patches, you could buy a single patch, you could buy a pack of 12, you could buy a case of 10. And same with the the other patches are in packs of 10 or in a case. So we can get some samples out to you. Let you give it a try. The 300 by 700 millimeter patches, they’re very easy to cut.

As well and very easy to use as far as just peeling everything off, all of the packages have your step by step instructions on what you do, which film to release, what, everything that you do, very clear, very concise to make sure that there’s not anything, our customer service is trained, you can call the 800 number if you’re having problems they can talk you through something, but yeah, definitely give us a call place an order through the website or contact rod.

Allen Hall: Yes. And it’s FibreGlast, F I B R E G L A S T. So you just Google that and you’re going to get to Michelle’s website. All right. For Bergolin, how are we getting a hold of Bergolin, because you guys are over in Germany and this podcast goes worldwide, so you’re going to have people calling you from all over the world.

How do they get a hold of you?

Marvin Hirdler: Yeah. I run the whole US business here, so I do the technical training, the commercial side too. Also we operating or helping also the training companies like Redwood Academy, TSL Windtrade company too, to make sure that they get the hold of the materials. Sure.

So I trained the trainer. I’ve been there, I doing, two or three trainings a week right now because everyone is interested in the new materials for sure, right? So I make sure that they get their first training with me and then they can train their technicians Okay, we even have a process description where everything every step is perfectly written down with pictures.

So how close you have to go with the lamp? How many layers you have to you need to apply in one step that section? So if you have to help you apply or do a vacuum so I just want to make sure that there are no questions at all afterwards. If there are any questions, they always can call us.

Allen Hall: And your YouTube video you sent me today.

Yeah. Which is very explanatory, so yeah, you can get a lot of information. So easy, a lightning engineer can do it. Yeah. I am not a composites expert for sure. Actually, this was the idea we had.

Get it that simple everybody, huh? Bergolin is B E R G O L I N. If you just Google that and put UV behind it, you’re going to come across the UV material.

It’s fantastic stuff. So if you’re a technician, you’re an operator, you’re an ISP looking to speed up operations or extend your season, you need to get a hold of Michelle. I need to get a hold of Marvin and talk UV cured resins. So it’s the future. So thanks to both of you being here. Thank you.

Allen Hall: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall, and I’m here with Rosemary Barnes, Matthew Stead, and Yolanda Padron. And three out of the four of us will be in Melbourne Australia talking to a number of operators and interested parties about WOMA 2027. Matthew, where will we be the couple of days we’re in Melbourne?

Matthew Stead: So, um, first of all, we’ve got the Pullman, uh, East Melbourne, which is, uh, where the venue will be for, for 2027. Um, so that’ll be our home base. Um, we’ve got around about eight meetings planned already. So what we’re doing is we’re talking to the operators and a few other industry, um, players about [00:01:00] what we need to talk about, how we’re gonna move the industry forward in Australia.

Uh, so it’s gonna be jam-packed, but there’s a little bit of time left on the Friday afternoon if there’s any late-minute, um, people that wanna get in contact and catch up with us, um, for next Thursday, Friday, or actually Friday. Uh, so yeah, it’s gonna be a, a jam-packed time. I think we’re gonna be tired, too many coffees, and talking to all the key, all the key operators, uh, about what they wanna hear about and how we can move the, the industry forward.

Allen Hall: And if someone wants to put an input into the WOMA panel about what will be discussed at WOMA 2027, Matthew, how would they do that? How do they get ahold of you?

Matthew Stead: Well, we have a wonderful website, and that’s got all the details you could ever want. Um, you can also register on the website, so please register.

Otherwise, um, I’m sure we’re gonna be a sellout this year for sure. So woma2027.com.

Rosemary Barnes: I just wanna add that when people talk to [00:02:00] me about the event, they always say how they love that the topics are so relevant, and the reason why that they’re so relevant is because we make sure to go around to operators and find out what are the issues that they’re really dealing with.

So anybody that’s thinking of attending, even if you can’t, you know, meet us up, meet up with us in Melbourne, get in touch and tell us what are the, yeah, what are the topics that you’re struggling with that you’re not, um, you’re having trouble finding enough information, having trouble finding the people that can help you.

And y- yeah, like we take all of that information, and that’s how we come up with our agenda each year. And yeah, I mean, for us, that’s the, the main thing is that this has to be really relevant, up-to-date information for the industry, and we need your help to make sure it stays that way. I

Matthew Stead: mean, that’s what we’ve done the last two years, so this is– we’re just repeating the formula, um, listening to the operators and getting the good topics and the good speakers.

Allen Hall: Well, Vestas has had a good quarter. Uh, the, for the last couple of years, honestly, s- [00:03:00] Vestas has been really thin on margins. There was questions about it continuing on. Rising costs mostly, uh, supply chains, especially during COVID, were bad. Uh, and, uh, but for the most part, the shareholders stayed attached.

Well, that story is changing rapidly. The world’s largest turbine maker posted second quarter operating profits of $400- €46 million, more than double what the analysts had expected, and it’s raised its full-year margin guidance alongside half-year results for the first time in a decade. The shares climbed about 20% in Copenhagen, adding roughly €4.7 billion of market value in a single session.

Now, the chief executive, uh, Henrik Andersen, ha- put it plainly to, uh, uh, in a couple of news sources that something much bigger is happening and Vestas is gonna be the, the leader in wind. That’s how I read it, that everybody [00:04:00]at Vestas was super happy with the, the change in direction and things were moving up steadily.

But a 20% jump in a day is remarkable. You don’t see that in large industrial businesses like wind energy. Matthew, this has real implications on what happens next for Vestas because success like this usually means more orders.

Matthew Stead: Yeah, I wonder what’s going on under the hood there. Um, I mean, Vestas is a quality company, although, although can I just do a quick segue?

How many turbines were installed in Denmark in the last, uh, two years? Like last year and the year before?

Allen Hall: I don’t know. How many?

Matthew Stead: I believe it was eight turbines installed onshore in Denmark last year, and the year before it was 12. So, you know, maybe, maybe Vestas needs to focus on their own backyard a little bit as well.

Allen Hall: I’m not sure there’s a lot of opportunity there. Yeah, onshore.

Matthew Stead: How can you ever be full? I mean, there’s always, um, [00:05:00] uh, you know, um, you know, resiting or, um, you know, upgrades and-

Rosemary Barnes: You know what? Allen and I are probably gonna get some time in Jutland, uh, later this year, um, and that area and the old wind turbines there was actually the inspiration for my whole YouTube channel.

It just, ’cause there’s, you know, there’s turbines there from, the earliest one is, um, from the ’70s and still going. I think it’s one and a half megawatts, actually huge for, for that time. Um, and it was like community made, um, at Tvind. But anyway, I’m interested to revisit the site and have a look and see are these, you know, all these old turbines still there.

It’s only, like six years since I went through and did the experience but for the most part, they don’t seem to be yet pulling down the, the small old ones and putting up big ones. There’s a lot of, a lot of them are community owned. Um, and yeah, I mean, Danish people love wind turbines, but there’s only so many that you can have onshore.

Like, people are happy to live near them by, you know, the standards of people in other countries, but you don’t want [00:06:00] one in your literal backyard. I think that there is, there, there is a, a limit to how many more onshore wind turbines that you can get in that area and offshore expansion is the more likely way to go.

Um, and also I think it’s, it’s, it’s good to recognize that if you have a domestic only or a domestic first strategy, that will only get you so far and then you have to expand, and I think Denmark did that really well. I think Germany a little bit less. I think that Enercon were a bit surprised, um, by their strategy.

It, uh, they had a real hard time anyway when they had to transition away from mostly Germany to getting overseas. And obviously, like if you look at China, they have most of their installations are in China. They are trying so hard to get outside of China because it’s not, like even a market as big as China, it’s got decades to go before it will be full.

Um, you can still recognize that that’s not your, like long-term strategy for growth has to involve expansion, I think.

Allen Hall: I think Vestas, regardless of what happens in Denmark, is making a play for the United States. That seems to be [00:07:00] where a significant effort is happening at the moment and on offshore. Their– Vestas seems very excited about the offshore opportunities.

Of course, there’s a ton of wind turbines gonna be installed in the UK and, and all around Northern Europe. Offshore, the opportunities to buy turbines, there’s only a couple that you could get today. Uh, uh, the GE Vernova offerings I, I don’t think are gonna fit the mold, and I don’t know if GE’s even actively selling.

So their competitor realistically is Siemens Gamesa, which does seem like the smaller player at the minute versus Vestas, which is heavily pushing the V236 and will fill order books like crazy, I think, uh, just based upon the, the history they’ve had and everybody knowing who they are. So Also on the move in Australia, right?

Vestas is huge in Australia right now.

Rosemary Barnes: I think it’s really good that their, um, yeah, finances, uh, are [00:08:00] looking a bit better ’cause it’s been funny. Like, I tried early on in my wind career to invest in, you know, wind turbine manufacturers knowing that there would be immense growth, and I was right. There, there was immense growth.

Not that that was so hard to figure out that there would be, but it did not lead to any kind of, um, return on, on anything, you know. Like, that did not keep pace with the just general market. Um, so I, I stopped trying to, stopped trying to invest to that. But it has been really, really hard for the companies to, you know, raise money or y- you know, do any of the things that they need to do because they’ve always, like, they’re growing, growing, growing, but finances has been so tight that it has been a real constraint on the amount of engineering that they could do, and I really hope that Vestas are gonna take this opportunity that they’ve got compared to, you know, a lot of the other manufacturers.

Vestas do have really strong, um, innovation and, yeah, engineering capabilities for doing– you know, developing new technologies and improving them, and I really hope that they’re taking this opportunity to build that up. There are a lot [00:09:00] of very good engineers with a lot of experience in the industry in that area that are working in other fields at the moment because, you know, there’s been a lot of contraction in Denmark.

So I don’t know, it seems like a really good time to hire back some of that really in-depth knowledge and, yeah, get a- get ahead of, you know, some of the future quality problems. We’re going through such a hard time at the moment from the fast development that happened in the 20-teens when there wasn’t a whole lot of money around.

We’re dealing with quality problems now, so, you know, maybe we can get ahead and not have the next round of them if we can invest in just a lot more, uh, engineering capacity.

Allen Hall: When you have success like Vestas has, usually the upper level management and some of the executive team starts getting pilfered, that they’ll get offers to repeat that success at another company, and it sounds like that process has started already.

There’s a couple of executives that have recently departing or are in the midst of departing from Vestas. [00:10:00] I would see that continuing f- at least for the next six months, uh, because everybody wants to repeat that, right? If you can get a 20% increase in your valuation overnight, uh, I can, I can list a number of companies, regardless of industry, that would love to participate.

Even in a 5% increase, that would be remarkable. So, um, Vestas is gonna have a hard time holding onto this. That’s just the nature of the business where things are successful, people will wander. And Rosemary, I, I think they’re– And Yolanda In, in my book, Vestas should sort of s-stand down and just make quality products.

I’m not sure you sh-should tinker too much at the time being and just make the good stuff better. That seems like a way to really increase profits.

Yolanda Padron: Yeah, I mean, solving a lot of the issues that– And, and that’s not just a Vestas exclusive thing, right? All of these OEMs have some sort of issue that maybe– I know Rosie’s touched a lot on, on it, where [00:11:00] you build this version A and then version B solves one of the small little issues, but now it creates another little problem, and then you have version C, and then everything just kinda has its own niche little issue, um, that really expands over time.

So if they could solidify what they already have in, in a, in a model that, that would help them just even keep a lot of their customers, I think that’d be great, and it would help, certainly help them, um, not continuously, like, rotate around the customers, ’cause it almost feels like, at least in the States, right, you, you get GE to be really, really strong and have a huge market share, and then GE starts focusing more on gas turbines, so then they all go onto Vestas, and then they all go onto Ontara now.

Um, and then just, you know, just kind of everybody starts cycling through them because they just kind of want something that’s better quality than what they’re getting in the long haul.

Matthew Stead: Allen, you, you talked about you think there’s something big under the hood. I think you, you [00:12:00] thought that maybe Vestas was angling towards something or being quite bullish.

Do you think that they might take over GE Vernova?

Allen Hall: I don’t think they’re gonna grab Vernova, and I don’t think Vernova is for sale at the minute, but I wonder if Siemens Gamesa is, or Nordex. I mean, Nordex has done terrific the last couple of quarters and is making inroads in places that I didn’t think possible three, four years ago.

Uh, the European marketplace is be- becoming really unique in that sense that there’s a lot of money being put out. But is there a sole perfect solution for Europe? Not at the minute, ’cause you got two competitors there, and then China trying to, to work its way in. Will the Europeans come together and form something more united, even if it’s just a partnership, a loose partnership, versus letting China on the shores?

We’ll see. 64 of the largest machines that Vestas has builds are standing off the German coast, but one blade is missing a [00:13:00] piece. We’ll talk about that when we come back.

Speaker: Are you overspending on lightning repairs? Most operators are because solving lightning damage is complicated. Weather Guard Lightning Tech helps operators reduce lightning damage. Our innovative StrikeTape lightning diverter protects over twenty thousand blades worldwide. Now, StrikeTape Ultra installs faster than ever.

Allen Hall: Well, Germany’s largest offshore wind farm is now fully installed, and EnBW confirmed this, uh, past week that all 64 of the Vestas V236 15-megawatt turbines are s- standing at the He Dreiht wind farm about 85 kilometers northwest of Borkum. Uh, 960 megawatts, [00:14:00] 2.4 billion euros invested. Man, these offshore projects are expensive to get installed.

Uh, so it’s power for roughly 1.1 million households, and there’s no state subsidy behind any of it. And so this is a little bit of a u- unique situation. Uh, th- well, the one footnote about the wind farm is they had a V236 blade break and fall into the North Sea, and they had fished it out and I think I passed along s- pictures that I saw online of, uh, one of the police boats pulling the shear web out of the water I don’t know what to think anymore about some of these offshore blade issues.

Obviously, Vestas is very conscientious about it and will be doing RCAs and engineering reviews and all the above to go identify what the problem is. But it does just lead to a little bit of a pause of do– what is going on for some of these offshore [00:15:00] wind blade installations or, or whatever’s causing these blades to break?

Do we have a good handle on it? Yolanda, is– are we following up on all the design details so that we can prevent these things in the future?

Yolanda Padron: I mean, I’d, I’d hope you’d be following up on the design, right? Like, and, um, but I think there is still a little bit of a disconnect from, from what we’ve seen, and again, not just Vestas exclusive, um, between the people who are designing and the people who are manufacturing, the people who are in operations, right?

So, uh- The, from what we’ve heard, uh, this could have potentially been a, um, partially because of a transportation issue, which is what happens a lot in onshore. It’s a lot more common than we would like it to be. Um, and so that even goes beyond what would go on in the design studio and what would go on in the manufacturing and what would [00:16:00] go on even just for the people that are running the site, right?

So, so some sort of, um, in between, uh, EPC error. Um, but yeah, I just think that, like in a lot of industries, there should be a lot more communication between all of these teams on the lower level, so that way a lot of these problems can, can be avoided.

Allen Hall: I’m wondering if it’s actually an issue on the, the testing side.

And, uh, the one question that just popped up, and we saw from the ORE Catapult, uh, survey that’s being conducted at the moment, and if you haven’t participated in that, you just visit ORE Catapult and answer some of the survey questions. But torsion on a blade, which is very difficult to test for, and it really isn’t tested for today, but does happen during the move and the transportation of these big offshore blades.

Is it one area that we need to do a little more work in or maybe spend some more time focusing on it to see what is happening as blades are [00:17:00]moved?

Rosemary Barnes: The thing about te- torsion is that it is much more significant as blades get longer. I can’t, I can’t remember the equation off the top of my head, which is, um, bothering me.

But I think it scales with, like, the fourth power or something of, of length. And so whilst it was always a bit of a problem, it’s much more of a problem as it gets, as blades get bigger. I mean, they’ve never, like, fully tested a blade, and there was always a lot of reliance on, hey, y- you know, like we’ve tested certain things that is possible to test in a test facility on the ground.

But they also rely on their decades of experience of how blades actually behave in the field. But, you know, remember, that’s a real lagging, lagging indicator because y- you know, their decades of experience is mostly with lots smaller blades. Now, blades are really different because they’re longer and different effects are, are taking over.

It’s not just, uh, torsion, but it’s also the laminates get much thicker, and then y- you know, you, you have issues with the way that they’re curing, [00:18:00] and there’s a lot more just space for, um, defects to be present in a really thick laminate All of those things add up. Oh, yeah, then add in addition, like new materials, carbon fiber is new, and then new ways of producing it, you know, pultrusions, um, all kinds of different materials like balsa’s being replaced with foams and, um, like, you know, 10 times that number of what sounds like a small innovation, but all of these things have the potential for damage and don’t have a really long track record in the field to be able to kind of calibrate.

We do need to remember that, like, when you do something new, things are gonna break, uh, sometimes, they’re gonna fail sometimes. If they don’t, then you’re definitely being too conservative, and your product is costing more than it should, and nobody wants more expensive wind energy, right?

Matthew Stead: Rosie, Rosie, I, I know you’re doing some, some excellent work on, um, industry studies around erosion and temperature and so forth.

Um, I just wanted to let a little secret out of the bag that, um, in the future there will also be some [00:19:00] other studies on torsion and blade twist and blade dynamics. So, um, just a few things are in, in train at the moment, which I can’t share, share, but, uh, watch this space around better understanding blade twist.

Allen Hall: The Hydride wind farm runs on European turbines, but the next one might not. Two governments with two very different answers on who gets to build Europe’s wind fleet.

Delamination and bondline failures in blades are difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. CIC NDT are specialists to detect these critical flaws before they become expensive burdens. Their nondestructive test technology penetrates deep into blade materials to find voids and cracks traditional inspections completely miss.

CIC NDT maps every critical defect, delivers actionable [00:20:00] reports, and provides support to get your blades back in service. So visit cicndt.com because catching blade problems early will save you millions

Well, two countries and two decisions, one question. In Scotland, the UK government blocked plans for the Chinese manufacturer Mingyang to build a turbine factory, uh, near Inverness on national security grounds. 1.5 billion pounds of investment, up to about 1,500 jobs. And First Minister John Swinney has asked the new prime minister to reconsider.

And the UK energy secretary minister called that request irresponsible. Meanwhile, up in Denmark, Vattenfall has just won two offshore wind farms and will not say whether it will buy European turbines. Danish suppliers are not taking that quietly. So [00:21:00] the Scotland question about the Mingyang factory is at least being discussed again with the new prime minister in the UK.

It does seem like there’s a lot to do and get the government formed and make all this stuff happen. But I don’t see a Burnham administration changing the outcome for Mingyang, but I could be wrong. At the, the same time, Vestas is pushing for a more Eurocentric focus and to really keep out the Chinese.

Uh, something has to give here pretty soon.

Matthew Stead: I actually think Mingyang should, um, set up a factory in Scotland. I, I mean, what’s wrong with that? I mean, uh, why is that a security issue?

Rosemary Barnes: Set up the factory and put the, like, whatever you’re worried about, put protections in place for it, require it to be a local joint venture or whatever.

You know, we’ve seen the blueprint in many of what used to be, you know, less rich countries. That’s how they, you know, got a head start on some of these technologies. It’s not like, I don’t think that China [00:22:00] has a head start on wind, wind turbine technology, but they certainly have different ways of doing things that, um, yeah, we could, we could learn from.

But I think across the board, wind turbines, batteries, solar panels, whatever, let them set up factories, put the rules in place that mean that your country benefits from it and you’re getting the, you know, the information transfer.

Yolanda Padron: Do you think that’ll, like, impulse a lot of these more established European companies to maybe start fixing some of the issues that they’ve known about for, for a while, um, particularly regarding the blades and everything that we’ve talked about earlier?

Like, there’s enough competition there, so maybe they need to start looking a little bit more deeply into their problems.

Allen Hall: Do we think that Chinese operations have been out front, forward, honest, I’ll even use, about their blade issues?

Rosemary Barnes: No, but this is a good way to find out, isn’t it?

Allen Hall: Governments decide who is allowed to build a turbine after a discussion on Scotland.

Uh, but, but [00:23:00] occasionally, a court decides what a turbine legally is. India has just settled that question, and the reasoning should be of interest to anybody who ships machines across a border right after this. As wind energy professionals, staying informed is crucial and let’s face it, difficult. That’s why the Uptime Podcast recommends PES Wind Magazine.

Whether you’re an industry veteran or new to wind, PES Wind has the high-quality content you need. Don’t miss out. Visit peswind.com today. A tax fight in India has produced a definition every turbine supplier should read.

Is a wind turbine bolted to a concrete foundation movable goods, or is it immovable property? State tax authorities argued immovable, which would have [00:24:00] taxed erection and commissioning contracts at 18% instead of 5%. The Andhra Pradesh, uh, High Court disagreed, and on the 12th of August, the Supreme Court declined to interfere.

The reasoning rests on something this whole industry takes for granted. A turbine can be taken down, moved, and put back up. So a turbine is a movable object, and it has less taxation. Bonus. So this is a really interesting discussion that’s happening in India because it’s probably symptomatic of things we’re seeing elsewhere across the world about taxation for wind turbines, right?

That, um, if there’s a way to tax a wind turbine, we’re gonna try to do it. This is a unique way, uh, that happens in India where depending on if it’s permanent or movable, the tax rates are different. I, I guess that would apply to a lot of components inside a wind turbine too, Matthew, don’t you? Like the, the generator, the, the big heavy things, [00:25:00] gearbox, generator, blades, rotors, tower sections, would be taxed at a, a lesser rate.

Matthew Stead: I agree with the court case that it’s all movable and, uh, you can actually buy turbines on the secondhand market, can’t you? I mean, if I wanted to buy, yeah, whatever, whatever, I could buy one and, and put it up in my backyard if I had a bigger backyard. Um, so yeah, I vote for movable. I vote for lower taxes.

Yolanda Padron: The way that it would work a lot of times in the US is, I mean, it’s, you pay, the company itself pays a lot less than they would’ve over time, right? Just by pure, the, the regular kind of tax laws. Um, but the community, there’d be just direct donations to the community, so then they’d get, uh, like money would actually come into the community where the turbines were being built instead of just distributed around the state, which I mean, in a state as big as Texas, it gets, um, but easier for that c- um, that county to get a lot more, uh, funding than they would typically get if it was [00:26:00] through a big enough area.

Um, but yeah, no, I agr- I completely agree with you guys that, that this should be a movable good. I mean, how many times have we seen, uh, even just a blade, um, that it looks like it’s, uh, just a, a failed blade that they have to go in and replace, and then they take it out, fix it, and then just bring it back to the same site or take it to another site across the country.

And, and to that point, like if you were to h- judge it as something that’s immovable, would then any blade replacement just not be taxed? Because then it’s, you’re moving that one component and two, but it’s essentially the same turbine. Like, I don’t know how that all would make sense.

Allen Hall: I think the Uptime Supreme Court agrees with the Indian Supreme Court that wind turbines are movable, and that’s good.

Vermont and Florida: A Key Difference

Published

Can’t swear that the story here is authentic, but it sure rings true.

Vermont is a somewhat quirky state, but it protects its citizens very well. FWIW, this is where I want MY tax dollars going too.

Florida is a deeply red state that, true to form, wants as much ignorance as it can possibly produce. Educated people aren’t voting for people like Ron Desantis.

Republicans: Will This Work?

Published

on

The GOP is asking American voters to believe that “radical left Democrat extremists” are leading the country into socialism/communism. They’re hoping that this fear will outweigh the electorate’s understanding of the damage that Trump, with help of congressional Republicans, is inflicting on this nation in the form of the war in Iran, destroyed relations with allies, inflation, shoddy education, environmental collapse, and threats to Social Security and Medicare.

As we all know, the rate at which a lie becomes accepted as true is a function of the frequency that it is repeated.  And God knows, we see this crap about communism every time we turn around.

But this looks like an unwinnable battle.  Virtually no one wants to abandon free enterprise.  Moreover, Trump’s abysmal polling numbers reflect the fact that is largely despised as a criminal–the most corrupt figure in U.S. history.

How would you like to be campaigning to retired baby boomers on the platform that we cannot afford Social Security any longer, because we’ve siphoned off huge amounts of money, like our president’s “vanity war,” with only further downside in sight, that is costing $1 billion a day?
