Joel Saxum: Okay, guys, we’re recording here. We’re live right now at blades USA 24. We’re sitting in the area where there’s some coffee and some conversations, ISPs, asset owners, some blade design engineers, and of course, a lot of solution providers. I’m here with Polytech came over from Denmark on a world tour.

You’re heading back to Denmark. You’re going to OMS in San Diego, so we’ll be over there. Okay. So I’ve got Thorbjørn Rasmussen, chief commercial officer over at Polytech and also Michael Drakmann Haag. I got it, right? Yeah. Perfect. Perfect. So chief technical officer. So we have two of the great minds from the Polytech team here right now.

Polytech, while they do a lot of different solutions they have some lightning protection things, they sell to OEMs, sell to asset owners, all the above, out of Denmark. They’re really known for the L shells. L shells is a product that if you’re dealing in wind turbine maintenance at all, you know that the leading edge is a problem and the L shells were developed for offshore use originally, correct?

And they have been installed some onshore turbines, some high erosion areas, or even people that are like, you know what? I think this is the solution. I don’t have to touch my leading edges for 10, 15, 20 years. I’m putting the big stuff in. So you guys have been behind the scenes, behind the curtain, working on another kind of version of that, but adjusted specifically for onshore.

Yes, tell us about that.

Michael Drachmann Haag: Yeah, so we’ve taken all of the great learnings that we’ve had on the yellow onshore, offshore products, and then we’ve taken and built. On those innovations. And then we designed a product that then is easier to install comes at a lower price point as well. And really sets aside from the more, you could say more complicated stuff that you get out in the industry.

But while still having the the great performance and also then we don’t need the material to cure at site, which we often see with coatings and other products. So I think we really try to say that. All of the good things we have from the offshore, we build in that, that into an offshore product.

And yeah.

Joel Saxum: So I would say, as you thought, so driving this market, primary market research, as we call it, of course, in the commercial world, did you have asset owners come to you and say, hey, this is great, but we’d like this?

Thorbjørn Rasmussen: Absolutely. We have been cooperating a lot with the ISP out there, getting feedback for installation method and and what was actually difficult or less easy for the, let’s say the premium version.

And then asset owners is when they, Take the decision very shortly sometimes they want to run a campaign So it should be easy accessible and so forth and all that feedback has gone back to Michael and the department and try to make sure that was incorporated in the solution And we can elaborate more on this one.

Joel Saxum: Yeah. Yeah, but I would say that it’s feedback from the last five years from the field all over the world. Yeah, the best kind of feedback. X. What’s happening. Empirical data from the field is what we want to change things on. Exactly. We could test in a lab all day, and that’s great. We need to do that.

But when we get results back from the field, that’s what we want. So let’s talk a little bit about the differences between the new Onshore product and what the L looks like. Offshore product was or is still, of course it’s still offered.

Michael Drachmann Haag: I think that the primary part that really sets it aside is the thickness of the material itself.

So the thickness of the material on the offshore product is thicker and thereby also having high performance, but it also entails that we need to tailor make that product into the specific blade. So it really provides a high performance, the highest performance in the industry. But it had to be tailor made to a specific blades.

Now we set aside with a thinner product that is more flexible and can be installed faster and can actually also be installed. Let’s say it’s a more, it’s not going to be tailor made to the specific blade, meaning it can be installed on all blades directly out of the box.

Joel Saxum: Oh, that’s fantastic.

Michael Drachmann Haag: And that’s, I think that’s really is one of the things that sets aside.

What we then took as innovations as well is that we have the split liner on LA offshore. And we took that great innovation and then we transferred that to a lawn show for ease of installation as well. That’s huge.

Joel Saxum: I want to touch back on the point of being able to install on different parts of a fleet.

So in the United States, of course, we have large wind farms. That’s a hallmark of kind of the market over here. And in those large wind farms, you’ll see sometimes, we deal with it at WeatherGuard quite often, you’ll see sometimes, four different manufacturers of blades and two or three different subtypes of blades in a specific wind farm.

And we just dealt with this one in an on one product. So if you have say let’s take an example of GE, the new GE generation turbines, the two Xs, right? Two five, two eight twos. They’re regularly come with 116 meter blades and 100 or 116 meter rotors, not blades, sorry, and 127. And Within those two sub models, you also have TPI can make your blades, LM can make your blades.

There’s a bunch of different manufacturers and there is little discrepancies between them. So if you had to have a custom made solution such as the L shells, the or the offshore shells, it would be a little bit more difficult. Now with the onshore version, you’re saying, Hey guys, you want to do a capital campaign?

You want to install on a hundred turbines? Here’s the product. It’ll work on every one of them. Yeah.

Michael Drachmann Haag: You just need to order the number of meters you need. And then the final adjustment right at the tip where there’s a big curvature on the blade. Yeah. That’s the point where you do a small modification, but that modification can be done on site.

Perfect. So perfect. That really either blade make or turbine model. It really just can be fixed on anything.

Joel Saxum: So let’s talk a little bit more about the technical details of leading edge protection. From an expert’s standpoint, we regularly hear, you should put on four meters, you should put on six meters, you should put on 10 meters.

You could do two meters of shells or three meters of shells and this much of a tape or this much of a coating. If you were, if you had a wind farm, and I know every one of them is different, say I’m going to put you in the middle of Texas. How many meters of this new product do you think you’d put on?

Michael Drachmann Haag: It really depends on your specific turbine, right? So the bigger turbines will also require more, a bigger length, a longer length of protection. But what we typically do, and we can do that for any site in the world, we can offer a calculation, a specific calculation for that specific site, that specific turbine, that allows you to exactly predict What do you need?

And we will then be able to sell you exactly what you need. No more, no less. Then there might be some some campaigns where you fix it, fix the number to installing 10 meters, because that fits within a day of working day. And then it might be that is the right option for that specific site. It really depends based on the customer.

But I think we try to deliver the calculations behind, but also the product that can then fulfill that.

Joel Saxum: So if an asset owner or an ISP or an asset owner and ISP in conjunction, contact Polytech to say, Hey, we’re looking at your leading edge protection solutions. You guys can also offer the customer success first support part of that too.

Hey guys, we believe through calculation that this is how much you need. So when you’re contacting you guys, you’re contacting experts in LEP.

Michael Drachmann Haag: Yes. They’ll get a report that then says what is the expected length you need, but also what is the expected repairance was. If there are any repair intervals.

So that means that they can already now plan the predicted maintenance. Yeah. So when do you need to go and look at the blade again?

Joel Saxum: Yeah.

Michael Drachmann Haag: And when do you then need to maybe plan for repair?

Thorbjørn Rasmussen: Okay.

Michael Drachmann Haag: Again, depending on site conditions and terminal conditions.

Thorbjørn Rasmussen: Just a little caveat to this calculator. It’s based upon two heavy input.

The one is 20 years of weather data from NASA. Simply put into a database. And then correlate it with many hours in the wind erosion tester, sorry, the rain erosion tester. And then combining, of course, with verification on let’s do this. And according to the new standard and then having feedback from certain areas of the world saying we calculate this on this coordinate, how does it actually look after seven years?

Joel Saxum: Ground truthing it. Yes.

Thorbjørn Rasmussen: And then the service department or OEMs, the asset owner has then feedback to us and then correlate it together with us. Yes, it actually matches what we’re seeing out there. A little bit less or a little bit more, but more or less matches. We are pretty sure this tool is is the right one for the acetone.

And the great thing is there’s no price tag to it because we offer it for free. Everybody likes free.

Joel Saxum: It’s where they get you at the end on the LEP prog. Okay. Okay, so let’s go back to this LEP prog, the new one. You guys have of course been through the rain erosion testing. You’ve done your due diligence in the design phase and in the testing phase.

But you’ve deployed it already as well, too.

Michael Drachmann Haag: Yeah, so we have already installed it in a site in Denmark. That was our first installation. And then later last year, we also installed it in Denmark. I would say challenging conditions in Canada as well, really to get the winter season across, so the cold temperatures.

So we’re going to go and inspect those turbines here in the coming the coming months as well.

Joel Saxum: So another thing I want to touch on here, and we talked about a little bit off air, but we’re all in the wind industry, and when you talk about aftermarket upgrades, if you’re talking about, it doesn’t really matter.

VG panels, our strike tape product, the polytech shells, any kind of LEP, any addition or add on to a blade. They operate in a crazy environmental conditions. If you’re listening to a podcast, you know this. It’s in rain, it’s in dust, it’s in bugs, it’s 300 km an hour tip speeds, it’s all these things. So unless those products are installed correctly, right?

When someone gives you a set of instructions please, this is begging the industry and all the technicians out there, please do it per the instructions. There’s a lot of work that has gone into those instructions to make it so that the products last on the blade. What have you guys done with the new product to make it easier to install in the field to we guarantee that durability, longevity, efficacy of the product out there?

Michael Drachmann Haag: So the split liner is really one of the things where we aid the operator in installing it correctly. What we also do is that we we allow the product to apply with a water film. So you can squeeze out any air that might be there. I think that’s a really benefit for product like this.

And then what we’ve done is that we’ve also selected materials that are robust against these different conditions that might be there. Low temperatures, high humidity. And then one of the other elements that we also found as being challenging is the edge sealant that is being performed on typical mini products that we’ve removed from this product also too.

Make it a fast installation. One less step. Yeah, exactly. And you don’t have this liquid chemical on site that needs to, that needs secure. . So it complicates or removes a bit of complication. In the product and in this, the installation. So less steps, less complicated, easier to work with.

Yeah. Risk of failures.

Joel Saxum: So of course we don’t want to give away your secret sauce, but if you were to give me like. The quick 5 steps. What does it look like to install and how does the product come?

Michael Drachmann Haag: So if we take the product That is right there. Perfect. The product here is that’s the product, that’s the material that we have.

So it comes as a flexible film.

Joel Saxum: Okay.

Michael Drachmann Haag: About 300 millimeters wide and it fits the blade perfectly. Okay. The curvature of the blade. When we look at the the adhesion method, then we have the split liner. Okay. Okay. So it comes here with a split liner that the first parts in the in the sensor is removed and then it’s installed in the center.

And then you have fixed it fixated the products right to the blade. And then you install the sides afterwards. And that can, what we’ve done so far in, in our sort of application environment that we have at Polytech in Bramming is that we’ve installed it in a continuous length as well.

Joel Saxum: So if you’re putting on six meters, eight meters, 10 meters.

You’re getting a roll of this, basically.

Michael Drachmann Haag: You’re getting a roll of that, and then you install it in one piece. Of course, if you’re hanging from a rope, it might be a bit more difficult to do. But but from a basket, we’ve succeeded in installing it in a continuous length.

Joel Saxum: Okay. Like a traditional LEP product, you’re making sure, you can’t have cat two, cat three, bad damages in the leading edge.

Those need to be cleaned up by a technician. Blade preps, we’ll do a little sanding, do a little alcohol cleaning, make sure the thing looks beautiful. Okay. Then from there on, do you need to, is it a spray bottle of water to put on there so you can squeegee it out?

Michael Drachmann Haag: Yeah, typically spray water on the blade, but also on the product.

Joel Saxum: Okay.

Michael Drachmann Haag: Because then you don’t have that immediate tack.

Joel Saxum: Yeah.

Michael Drachmann Haag: And then you, this allows you to squeegee out any air bubbles that might be. It’s like putting window tint on. Exactly.

Joel Saxum: Right? I think Americans are good at that as well. Perfect. Yeah. Especially in Texas, everybody has tint on their windows because it’s too dang bright down here.

Okay so the product itself very interesting different than what you feel in the rest of the market, right? I’ve never put my hands on an LEP product that felt like that. But you can feel that it would almost, so I’m talking rain erosion testing, that it would almost cushion against rain droplets rather than take a hard impact.

Michael Drachmann Haag: Yeah. And definitely that’s where we’re combining the the thickness of that absorption power of the material, but also ease of installation. Yeah. So if it becomes too thick, the installation becomes a bit more difficult to do. So we are finding the right balance between that thickness and then the, also the, let’s say the performance in the rain version tester.

Joel Saxum: All right. Is it available now?

Michael Drachmann Haag: Not for serial delivery. Not today. Okay. But it will shortly be at least.

Joel Saxum: Okay.

Michael Drachmann Haag: All right. We are working hard in our facilities and bombing really to to make the product ready.

Joel Saxum: Perfect. Okay. So let’s so we’ve got the product. We’re also gonna shift gears here.

We’re gonna talk Polytech for a little bit. So Thorbjørn you were telling me that you guys are making some moves.

Thorbjørn Rasmussen: Yeah. But just to confirm that in a short while is in a few months. In June, we are absolutely sure that we can deliver to the market. So that’s why we’re bringing it to the market now.

So people can feel in touch and get an idea. And then of course, maybe plan for late season. We have been Working from Europe to towards U. S. with travel, visit, and so forth. And we will continue doing that, and our normal staff is still available. We have strengthened a little bit. But we actually had a sleeping company in U. S. And we’re probably going to reactivate that in order to create also a warehouse situation that we can deliver with short notice out of, Out of the U. S. Oh, fantastic. Yeah. And simply also, some of the feedback we’ve gotten is that ease the installation, ease the access, and have a decentralized warehouse situation in the U. S. And we try to listen. And so within within this year we are planning to activate that as well. Yeah.

Joel Saxum: From a customer success standpoint, it’s fantastic to have someone. Denmark and the U. S., you’re six, five, six, seven, eight hours apart, right? So it’s nice to have someone here to help the customers have that warm, fuzzy feeling that probably takes right down the road.

Exactly. Fantastic. Okay, guys, so we’re nearing towards the end of what we want to chat about here, but I want to make sure that anybody that wants to see the product can get their hands on it. So we’re at Blades right now. In two days, we’re going to OMS. You guys will be in OMS. Yes. OMS. And then we’ve got global shows coming up.

We’ve got Wind Europe Bilbao, you guys will be there. Hamburg is of course the big one this fall, it’ll be there for sure. By then we’ll probably see some more installations. Yes. Anywhere else that you guys are going to be that people can visit?

Thorbjørn Rasmussen: Yeah next week we will be in Tokyo. With the Japan Expo then we will also have a couple of smaller areas in Europe and in and of course in October the annual fair in China.

Yeah. We also exhibiting there. And of course we will concentrate this year on this product launch, but of course you can always come by and hear about all our other solutions.

Joel Saxum: So we’ve got, if we want to reach Polytech, of course. That’s an easy one. If you’ve got a technical question, are we giving out your LinkedIn?

Michael Drachmann Haag: I think it’s best getting through the commercial guys first. He likes to talk, right? We need to focus on the product. That’s right. You’ve got stuff to do.

Joel Saxum: So what’s the best way to get a hold of Polytech if you need to?

Thorbjørn Rasmussen: It’s simply to contact me or one of my business development sales team.

The Mark Folley, or the Thomas Nilsson, and so forth. And but if you go to our website, you can find names and address numbers, email address etc. That’s probably the easiest way, and you’ll find me and my colleagues there.

Joel Saxum: Fantastic. Polytech. com, if you’ve got questions about the new LEP product they’re putting out, the existing LEP products they have in the market, or any other solutions.

Fellas thanks for coming on the podcast.

Thorbjørn Rasmussen: Thanks for having us. We’ll chat soon. Yes. Thank you.

Speaker: [00:00:00] The Uptime Wind Energy Podcast, brought to you by StrikeTape. Protecting thousands of wind turbines from lightning damage worldwide. Visit striketape.com. And now, your hosts.

Allen Hall 2025: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall, and I’m here with Matthew Stead, who is back in Australia, but not at home.

He’s up in Queensland. Or actually, not even on– in Queensland, technically. He’s on an island off the coast of Queensland. Where are you at, Matthew?

Matthew Stead: Uh, Moreton Island. It’s, uh, like a resort island off, uh, off of Brisbane, so beautiful outside.

Allen Hall 2025: Well, you need a little bit of resort time because you’ve been to two conferences, and you spent a good bit of time in Austria after that.

So you were at WindEurope in Madrid, and then following that, you went right over to Scotland for Blades Europe. So I wanna hear your thoughts. We’ll start with, uh, WindEurope and what was going on at that conference. It did sound like there was a pretty [00:01:00] good attendance, and some people that I have talked to about it really en-enjoyed being in Madrid.

It’s just

Matthew Stead: a bigger city. Um, first time I’d ever been to Madrid, and, uh, yeah, the show was amazing, actually. I was, I was a bit blown away by, uh, I think the OEMs were back out in force. You know, so like the Vestas, Siemens were, um, really– and Nordexes and so forth were really back out in force, so that was really good to see.

Um, the, some of the larger operators had really, really strong presence as well. So you could see that, you know, Iberdrola, Res, um, those sorts of companies were, um, really, you know, putting a big effort in and meeting their customers and, um, really showing, uh, the world who they were. So that was really, um, you know, really good to see.

There were so many people seriously. Um, the queues for food at lunch were, were, um, one of the major problems. Um, so, um, yeah, it was really a lot of people, so that was really exciting. Um, and I mean, for me, I was [00:02:00]trying to catch up with, with partners and friends and, yeah, it was, it was jam, jam-packed just meeting people in the industry.

Um, probably a few other things. So s- you know, SkySpecs and Aerones had a really strong, um, presence there. So, um, SkySpecs and Aerones were, were doing really well. Um, maybe one of the, um, surprises for me, and I know this has been a topic on a few other previous episodes, was there was a lot of interest in bird and bat detection.

I, I, I think there had to be, like, five companies that were, were– had really big setups, and it was a really, really big topic around cameras and so forth. So, um, that was a, a big topic. And, um, then there, there was a really, really strong, you know, supply chain, you know, from, from vessels to cables to, you know, repairs.

Allen Hall 2025: What was the ratio of offshore companies to onshore companies? I’m always curious.

Matthew Stead: You’re looking through the, the list. Um- I would, I’m only guessing it [00:03:00] was probably about 40% had an offshore focus of some kind. So it was definitely a strong offshore focus. Um, obviously, you know, a lot of onshore, offshore combined companies.

But yeah, definitely the word offshore kept on popping up a lot.

Allen Hall 2025: Because Spain is mostly onshore. Like, um, like 99% onshore, right? I think it’s a couple of small projects going offshore. Does it look like the onshore business is gonna pick up, uh, just in terms of the activity on the floor in Madrid?

Matthew Stead: Uh, yeah.

Um, I, I think, you know, like I said, you know, those big operators like the REZAs and the Iberdrolas and, and the OEMs, I, I think it’s just a given that, um, you know, things are buoyant. Um, well, they appear to be definitely very buoyant. Uh, I think we’ve heard, you know, some of the positive, um, financial news from a few of the OEMs recently.

So yeah, yeah, it seems like o- onshore is, is maturing further, further, further. And so you went straight

Allen Hall 2025: from Madrid, right, to [00:04:00] Edinburgh, Scotland. That was a change in weather, I would assume. Uh, probably about a 20 degree Celsius difference. 25 down to 15, yes. Whoa. Okay. Yeah, that’s a good bit. Uh, but the Edinburgh conference, that’s the first time that Blades Europe has been to Edinburgh.

I, at least I don’t remember them being there before. That tends to be a more technical conference than Wind Europe. Uh, the, the Blades conference is obviously focused on blades, and all the relevant experts in Europe do tend to show up there. What were some of the hot topics at Blades Europe this year?

Matthew Stead: Yeah, I think it was, um, an interesting conference. Um, I, I’d been to Blades USA, so I was able to contrast, um, Blades USA a little bit. I think probably the differences here were, yeah, there was definitely some strong, strong, uh, experts there, like you say. Um, you know, Birgit, um, our friend was, was in attendance and a few of her colleagues from Statkraft.

Um, I think, and or, uh, actually ORE Catapult, the, the [00:05:00] UK research, um, offshore renewable energy research, um, they did some great presentations. I really, um, they really shared some really good insights. So, um, ORE Catapult were talking about life extension and, um, you know, looking at the, the fatigue on blades and, uh, how they’re, how they’re going to perform and life extension.

So some great stuff from ORE Catapult there. Probably another key topic that came up was around, uh, sort of related to life extension, but also recycling. The, there was a really good session on the new IEC standard. Um, um, to, you know, full disclosure, I was actually on the panel. So I, I thought it was a great panel.

But, um, the new IEC standard for blade operations and maintenance, um, is really well a-advanced now in its development. Um, very strong risk focus, you know. So depending on the risk then drives your, your blade O&M program. [00:06:00] Um, so that was a, a great talk as well. Uh, and then maybe finally, um, something close to my heart, um, I think the, the, you know, the maturity of CMS companies.

There actually, there were five blade CMS companies there, which is probably the biggest turnout I’ve seen around blade CMS, um, ever. And so it was good to see that sort of, um, interest and growth, um, and the need for, for blade CMS. Uh, and, um, obviously the last one, lightning. So lightning always an issue.

Lots of discussions around lightning, um, you know, through Greece and a few of the, the, the Balkan go- Balkan states. On the blade recycling front, there’s a

Allen Hall 2025: company in Scotland called ReBlade that is involved in some of the recycling efforts. Did they give a presentation of, of what they’re up to at the moment?

Matthew Stead: Uh, yes, I think they did. Um, they’re talking about setting up a, a site in a, a [00:07:00] couple of sites, and I think Inverness was the, the location where they’re, where they’re setting up a site. The, um, the port is supportive, so they’re working through those, those, those challenges. You know, getting a site, getting transport and access to the blades.

Um, working out when, when the, when the blades will come to them. You know, the storage of blades. Um, the, the end, end uses for those blades. Getting all that supply chain, um, lined up was, you know, yeah, it was, that was quite thorough and quite, um, yeah, inspiring.

Allen Hall 2025: And on the CMS side, what are operators trying to monitor?

‘Cause usually have something in mind that they’re going after.

Matthew Stead: For better or for worse, there’s still some serial, um, failure modes. Um, and so the industry is looking at very particular, you know, challenges that, um, certain make and model have. Um, so root insert failures was definitely one of those, um, one of those topics.

Um, and that was actually one of the, the, the [00:08:00] roundtable discussions at, uh, Blades Europe. Some other, um, monitoring around, you know, lightning and- lightning damage and what’s happening with the LPS. That was also, uh, another big topic for, for monitoring. And then a few other sort of general, more, more general, um, you know, natural frequencies of blades and seeing if the natural frequencies are changing, indicating a change in stiffness, which relates to potential damage.

So yeah, there was– it was quite a mix of the types of, um, CMS that was discussed.

Allen Hall 2025: Has the digital twin finally died? Anybody talk about that?

Matthew Stead: There’s actually a current call-out for a new research project in Europe around digital twins. So, um, yeah, one of the larger, one of the larger operators is, is putting, pulling together a team to talk about digital twins, so-

Allen Hall 2025: I, I think this is one of the more difficult things to do, but just because you’re dealing with a variety of blades and blade factories and unique issues that pop up that are…[00:09:00]

You, you really can’t model until after they happen. And after they happen, everybody knows about them anyway. So what’s the point of the digital twin if you can’t detect things early? It, it, it is a great concept, but hard to implement.

Matthew Stead: Yeah. And why? Why would you do it? I mean, you, you’re only gonna do it if there’s a benefit, and what is the benefit?

So, but I think, uh, actually at Blades Europe, digital twins was not really a topic. And maybe one thing I forgot to say is that the, um, Wind Power Lab did a, a good, um, presentation on carbon blades as well, so.

Allen Hall 2025: The, the carbon blades are, is a very good discussion, just because the trend has been lately to scrap blades and bring new ones on site.

And the carbon can be difficult to repair, or it takes a long time to repair, and you just don’t have the manpower or woman power to go out and fix it. So the, the fastest option is to build a new blade. But it does leave a lot of blade waste, which is where the industry is not going. Uh, recyclable blades, which is [00:10:00] in process at the moment, will make that easier, but you just don’t wanna be recycling blades.

You like to be able to repair them. Composites are repairable. And it’s, it is so odd that they, they wanna continue on that pathway, but we’ll see. We’ll see. You don’t really learn the lesson until you do it.

Matthew Stead: Um, however, you know, the, the presentation on carbon blades was, um, you know, highlighted a lot of the challenges, but also highlighted some of the positives and the, you know, how they do help.

Um, and so there was a lot of support for carbon blades, but there’s a lot of unknowns and, um, and there was a lot of discussion around how do you even test if the LPS is working. Uh, it’s just impossible. So, you know, traditional methods on carbon blades, yeah, it just don’t work. So, um, but there was a lot of support that the carbon does bring benefit.

But yeah, I agree with you. There’s a lot of challenges there.

Allen Hall 2025: That’s one of the things we learned years ago back in the late ’80s, early ’90s when we, at least in, in the [00:11:00] States, started building a number of carbon fiber aircraft. And the repair situation and dealing with repairs in, in remote locations became difficult.

And you’ve learned how much training it took to keep an industry running, and you’re starting from zero for a lot of places that all he had worked on was aluminum. It, it’s a completely different world. You’re, you’re training tens of thousands of technicians around the world. You weren’t planning to go do that, and now you are.

So it just, it adds to the cost.

Matthew Stead: It also ties into the OEM, um, you know, providing, you know, details on how to repair those blades because they’re not, they’re not just a standard item, so-

Allen Hall 2025: No, you, you don’t wanna be grinding into a protrusion if you can avoid it. It- you’re just never gonna get it back into that original form because protrusions are in some part magic.

And taking a grinder to them is not gonna… It’s breaking the magic. All the magic will be leaving that protrusion when you do that. Yeah, very [00:12:00]difficult. Delamination and bond line 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 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, as we know, the wind industry has long been dominated by a handful of European and American turbine makers, uh, particularly in the, quote-unquote, “West.” Uh, but that landscape may be [00:13:00] shifting. Suzlon, the Indian turbine giant that nearly collapsed under about a $1.5 billion of debt just a few years ago, is back.

The company has unveiled a new turbine platform aimed squarely at Europe, and says it will build its first factory on the continent if it wins enough orders. Vice Chairman Girish Tanti, uh, delivered the announcement at the WindEurope conference in Madrid, where Matthew was Signaling that Suzlon believes its time has come.

And since you were there, Matthew, did you hear any news on the floor, any discussion on the show floor about Suzlon entering Europe?

Matthew Stead: Well, actually, yes. So, um, um, there was actually a good, uh, contingent of Suzlon people at, uh, Blades Europe. So, uh, they attended, uh, Wind Europe and then Blades Europe. Um, and I, you know, I was able to have a bit of discussion with them.

I think, I think, uh, they were quite optimistic about, um, [00:14:00] you know, moving back or moving into, into Europe in terms of manufacturing. Um, however, there was an element of skepticism. Am I allowed to say that? So they, uh, were, they were not completely, um, convinced that it’s gonna happen, but, uh, they were certainly excited by that.

It was definitely a, a clear possibility, but not a given.

Allen Hall 2025: Well, they have a, a new platform called the Blue Sky platform, um, which will have, I think, two turbines here, a 5 megawatt and a 6.3 megawatt, which is squarely aimed at Europe and also the United States, for that matter. And building a factory, though, doesn’t make a lot of sense if the cost driver for a factory in Europe is the European employees, which it tends to be when you hear the discussions about the cost structure, it’s about the employees.

I’m not sure why Suzlon would make blades or nacelles in Europe unless they could avoid tariffs or taxation, because India is a very [00:15:00] cost, uh, driven, uh, manufacturing facilities writing country. So why would you wanna go build another expensive factory, probably in the realm of a couple hundred million pounds, uh, if you’re gonna go do it?

It probably doesn’t make any sense to do that as well as just selling turbines into Europe. It seems like the easier path.

Matthew Stead: Yeah. And then you’ve got all the, like, the quality control challenges and, you know, you get the cultural challenges. So yeah, to be honest, I don’t qu- I don’t quite understand the logic behind that either.

Um, maybe there’s, there’s some things that we don’t know about behind the scenes in terms of tariffs and other, other incentives that we don’t know about.

Allen Hall 2025: Would you see operators taking, uh, a Suzlon presentation and maybe even writing plans for developing with Suzlon turbines in the next couple of years?

Is that a, a feeling that Europeans would, would do that, or is Vestas mainly and Siemens Gamesa so strong in Europe that it doesn’t make any sense unless [00:16:00] you’re in sort of the periphery countries of Europe?

Matthew Stead: I mean, my first exposure to a wind turbine was a Suzlon turbine in Australia, and there are many, many, many Suzlon turbines in Australia.

And they’re all, they’re all still working. They’re all still reliable. So I mean, from a reputation and reliability and, um Yeah, history point of view, I can’t see why not. I mean, you know, uh, the operators will see that, you know, they’ve proven themselves. They’re not new kids on the block. Um, and so why wouldn’t an operator think about it?

Allen Hall 2025: Well,

Matthew Stead: in

Allen Hall 2025: this quarter’s PES Wind magazine, which you can download for free at peswind.com, there is a nice article from Muelhen Wind Services, and that is a growing company. A lot going on there. Our friends at AC883 just joined Muelhen a f- few months ago, and is being part of that conglomerate. And, and we know that obviously building wind farm used to mean [00:17:00]consulting with dozens of contractors, and this is where Mue- Muelhen has really s- stepped into the breach here.

So from blade repair at one company and heavy lift cranes at another company, all that had to be managed separately. You’re calling s- different companies all the time. And watching asset managers and site supervisors do this, uh, it is a thankless job. Well, Muelhen’s trying to change that a little bit, uh, and they’re saying that that model no longer works, and I totally agree with them.

It’s insane. Uh, but so Muelhen has consolidated six specialist firms under its one brand, and covering everything from port pre-assembly to long-term operations and maintenance across Europe, the US and Canada, uh, and Asia-Pacific. Its CEO, Søren Hoffer, uh, puts it plainly, “The next phase of wind will not be won by turbine size alone.

It will be decided by the supply chain’s ability to execute.” Boy, [00:18:00]couldn’t say truer words. Uh, I’ve worked with Muelhen or my company, Weather Guard Lightning Tech, has worked with Muelhen on a couple of projects over the years, and we’ve always had, uh, great service from them, and we have talked to a number of operators that love them, that love using Muelhen.

So it’s not a surprise that they’re trying to grow and expand and make life easier for the operators.

Matthew Stead: Sounds like a brilliant move, really. I mean, you know, pulling all these sort of things together is, is a real challenge, isn’t it? I mean, coordinating all these subcontractors, um, getting to turn up at the right time, and yeah, I mean, it just sounds like a brilliant move, and I think that we need more, more, more efficient service companies to service the growing fleet.

So the more they can get organized, the better.

Allen Hall 2025: Yeah, the scale matters here, and the expertise matters. As we’ve have a couple hundred thousand turbines that are [00:19:00] operating in the, quote-unquote, “West,” it does make sense to have a larger player that has seen most of those turbines and has some experience with them.

It’s always the scary scenario when you’re working with a new company. Have they been on this turbine before? Do they know what they’re doing? Do they know- Lockout tagout. Even simple things like that come to the forefront. And the, the trouble is on some of these smaller companies that are in that business is that, uh, you just don’t get the level of service, you don’t get the level of response, you don’t have the horsepower if something were to, to go wrong on site.

They don’t have the cash to, to bring in a second crane or another crew to get this job done. It, it does become scale at some point. And, uh, for a long time in the wind industry, particularly United States, it, it has been a lot of, quote-unquote, “mom-and-pop operations,” and those are slowly getting acquired by the likes of Muehlhan.

I, I, I think this is inevitable at some point. Uh, from the asset owner’s, uh, desktop watching this go on, [00:20:00] how do you see, you know, a large operator interfacing with Muehlhan? Are they gonna do just one-stop shopping at this point? They’re, they’re not gonna have three or four different companies to work with, that they’re just gonna lock into, uh, Muehlhan?

‘Cause, uh, that’s what I see.

Matthew Stead: Yeah. I, I think, you know, from the, the WOMA Conference in, in Melbourne, we saw a bit of a, bit of a shift towards, um, outsourcing, at least in Australia Pacific region. And I mean, if, if you’re gonna outsource, um, you’re, you’re probably gonna join up with a, a Muehlhan, um, equivalent.

So, you know, that way it just takes some of the risk out of, out of it, so it, it sort of makes sense. Um, the other observation I’ve heard is that, you know, because of the seasonality of blade repairs, it’s really hard to keep hold of, um, blade techs. And so if you’re a global company, you’ve got at least some opportunity of using the ses- seasonality and keeping hold of the good techs and, um, you know, so, you know, you know, summer in, in North, North, uh, America, and then, you know, summer in [00:21:00] Australia.

So it, it, it allows these company, allows these companies to keep hold of their good people.

Allen Hall 2025: Yeah. And that, that’s always been the yearly problem, right? That you have a, a crew of a couple good crews in the summertime, and you come back the next summer and it’s a whole different group of people and yeah, that, that, that’s trouble for the industry.

Well, a- and it’s good. It’s fi- it’s finally good to see this happening, and I know, uh, we’ve talked about it internally here at Weather Guard of who to work with and who to partner with. We like working with companies that have scale, and I think we’re finally there. So it’s really interesting to see this article from Johan in PES Wind.

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. So when, when the energy prices spike like they’re happening right now, uh, the Iran war being one of the main drivers, and obviously gasoline prices have jumped quite a bit, here’s what happens.

The China’s clean energy sector goes to work, and they’re racing to make connections and make sales. As electricity prices jump up, gas prices jump up, everybody wants to try to find a cheaper way to provide energy to their countries or locales. Uh, China’s there to offer it. So it’s solar panels, batteries, EVs, and even wind turbines are, are looking for homes out of China.

Uh, for European wind professionals, [00:23:00] the most important part comes from Mingyang, right? So they were unable to get a production facility in Scotland, but they haven’t given up yet. They are still searching for a home somewhere in Europe. And as of today, I don’t think they’ve found it. They’re s- I think they’re still looking for some country to host them.

But how long is that gonna go on, Matthew? I, I think with the domination of Vestas and Siemens Gamesa in Europe and Suzlon trying to make an entry, will Mingyang and other Chinese manufacturers eventually find a home?

Matthew Stead: It’s interesting. I think, uh, if you look at the airline industry, you’ve always had premium providers, and you’ve always had low-end providers, and I think there’s always a place for all of them.

And so I re- I reckon they’ll find, I think they’ll find their place in, in the market and just, you know, it might just take a while. But they’ve got the strength, haven’t they? They’ve got the product. They’ve got the strength. So it’s just a matter [00:24:00] of time.

Allen Hall 2025: Yeah. I, I, I d- I do think eventually it will happen.

But Vestas and, and Siemens Gamesa have done a pretty good job of controlling it, and wind Europe, honestly. Wind Europe has not been a proponent of a Chinese manufacturer in Europe, so that generally will help slow down any business plans they would have But at the same time, there’s a lot of opportunities around the world that’s not necessarily in Europe, right?

South America has strong ties with China. They’re– And Chinese companies are, are starting production in China. There’s a lot th- things happening there. You’re gonna see that in Africa and other places. So it doesn’t necessarily have to happen in Europe, which is, I think Europeans and Americans think, “Well, we can’t have China in those locales.”

Fine. But it isn’t like China doesn’t have other opportunities to, to sell turbines or solar panels or batteries. There are plenty places on the planet where

Matthew Stead: people that

Allen Hall 2025: need

Matthew Stead: lower cost energy, and they’re gonna find them. Um, I did attend a, a panel [00:25:00] discussion on Türkiye, um, and the growth, and there was a lot of growth in Türkiye around onshore and offshore.

And so maybe Mingyang, that might be a, a place, um, for them to, to start, you know, on the doorstep of, of Europe. The stepping stone, so to speak. Stepping country.

Allen Hall 2025: Is there risk in that, uh, uh, if, uh, uh, Mingyang decided to put a plant in Türkiye? Is, does that come with some political aspect? Because I, I, I don’t remember.

Türkiye t-tends to play, uh, uh, k- kind of like Switzerland in, in terms of working with different, uh, political systems over time. Yeah.

Matthew Stead: I, I’ve had a bit more to do with a few, a few, um, sort of organizations in Türkiye recently and, um, you know, it’s highly professional, highly, you know, logical, and so I, I can’t see why it’d be a challenge.

So I think, yeah, that stepping stone into Europe might be a, a logical way to go. Well, maybe

Allen Hall 2025: we’ll see that in the next [00:26:00] couple of months. I don’t know. There’s gonna be a lot to happen there. There’s so much money being spent in Europe on renewables, wind, solar, battery, all the above, that there’s plenty of opportunity, and every company that has a product that’s gonna be trying to sell it in Europe right now.

It’s a smart move. Absolutely.

Matthew Stead: I think the other thing that we’ll probably be talking about a little bit more is EV trucks or, you know, electric trucks.

Allen Hall 2025: You think so?

Matthew Stead: I reckon we’ll be talking more and more about electric trucks.

Allen Hall 2025: Does Europe even have a, a le- a real true EV tractor-trailer, large truck?

What do they call… I guess they call it a lorry.

Matthew Stead: I don’t think yet. But that’s why I’m saying I think this is a topic that’s gonna raise itself. Um, I’ve, I’ve seen some numbers recently which says that it’s a bit of a no-brainer to go from diesel to, um, to battery now.

Allen Hall 2025: So is Tesla gonna be the, the winner there just because of their, I don’t even what they call it, the Tesla truck?

Is that what they call that now?

Matthew Stead: Not the Cybertruck, the, the truck truck.

Allen Hall 2025: Electric semi-truck. There you go. [00:27:00] Thank you, producer Claire.

Matthew Stead: I think you’ve gotta watch, you know, you’ve gotta watch BYD and a few of the other, the other, um, other companies.

Allen Hall 2025: Do they have something as large as what, uh, Tesla is offering today?

Because Tesla is offering a true semi or tractor-trailer

Matthew Stead: I, I, I must admit I’m not a, a huge expert on the topic, but I’m sure Rosemary is.

Allen Hall 2025: She drives the big rigs? Is that what she’s doing?

Matthew Stead: But I think we– Yeah, I think, I think it’s an in-interesting thing to watch because, um, certainly fuel prices in Australia are definitely pushing, um, this idea of, um, electric trucks.

Allen Hall 2025: Yeah, diesel prices are really high in the States. I- if they’re high in the States, I can’t even imagine what they are in Europe or Australia. They must be through the roof. So if you have a diesel vehicle, although they run forever and are pretty efficient, the price of fuel is insane right now.

Matthew Stead: And, you know, if you, if you take that a step further into mining, so Twiggy Forest, um, and Fortescue, you know, switching to [00:28:00] electric, uh, trucks and electric mining, yeah, it makes sense.

Allen Hall 2025: Does the math work out on that? Uh, obviously Fortescue is taking, uh, really a pretty significant risk in that they’re developing their own electricity generation sites via wind and solar and battery, the whole thing, and they’re converting some of their larger vehicles to electric. Does that hold a big risk, or is this just a financial no-brainer, particularly when diesel prices are so high?

Matthew Stead: Yeah, I think it’s a financial no-brainer. Uh, and that’s why partly I think we’ll be talking about trucks because, you know, once the finances make sense, um, there’ll be a faster transition. And I think, you know, Fortescue is not a silly company.

Allen Hall 2025: Fortescue is willing to dabble, right? So they’re willing to, to see where the technology is and spend a little bit of money and possibly it works out, right?

I think there’s– you have to take a little bit of risk if you’re in that business because you are spending so much money on fuel. [00:29:00] You can spend a couple million dollars playing in different areas to pick an eventual winner. Obviously, they’re gonna– Well, it’s not obvious at the moment, but it, it seems obvious to us being on the electricity side.

Electricity is gonna be the answer. Renewable energy is gonna be the easy way to do it, the lowest cost way to do it. There you go. Go do it. Well, American Clean Power’s event, uh, which is in Houston this year, will be happening June 1st through the 4th at the convention center downtown in Houston. It’s gonna be warm, everybody, so if you’re traveling from a cooler country like Denmark to Houston, bring something cool to wear.

It will be warm in June. It, it– Houston is just a very warm place, and it’s quite humid, so it’ll, it’ll be a, a unique environment. However, it does sound like there’s gonna be a, a, an– A number of interesting companies and a lot of people that are attending that event this year, and one of them is gonna be Matthew and EOLOGIX-PING with Weather Guard Lightning Tech will [00:30:00] both be down at the event in a booth and seeing everybody and, and, and meeting a whole bunch of, of, uh, new people that are getting into the industry, which is, to me, is always the fun part.

Like, we just meet so many really fun people. Uh, and Matthew, you know, we had a discussion internally about that, like, uh, our, our new, uh, chief commercial officer, Nikki Briggs, has been commenting. We’ve been talking to so many operators around the world, and after every, uh, little meeting briefing that we have, we do a post-briefing, and she goes, “They were so nice.”

And I s- yes, Nikki, the wind industry people are fantastic to work with. Like, they’re all focused on doing something positive, and they’re trying to, to do it the best that they can. And there’s a lot of constraints to it, and they’re making a number of hard decisions. But when we all come together at American Clean Power here in the States, hey, we can kinda commiserate and [00:31:00] talk about what’s happening and catch up.

And I feel like we need a little bit of catch-up time in this industry, particularly here in the United States.

Matthew Stead: Yeah. Yeah. I, I think, um, I, I definitely agree. And I, I found, you know, previously I used to work in the construction industry and work with engineers and, you know, transport, blah, blah, blah, blah, blah.

And actually, I found that the renewable industry, there’s a lot of really open people, really happy to have a discussion, um, not the big egos, so I completely agree. And, um, I’m thinking back, um, I first met people in the wind industry in, you know, around 2012, 2013, and, you know, I still know a number of those people and really appreciate catching up with them.

Um, so actually, Berend van der Pol was probably one of the first, and, uh, Birgit Junker was, um, maybe one of the second, so yeah. And I’m definitely looking forward to ACP.

Allen Hall 2025: If you’re, if you’re down in Houston at American Clean Power, definitely stop by a- and say hi to everybody from [00:32:00]EOLOGIX-PING and Weather Guard Lightning Tech, and hey, learn about all the things that are going on because both companies have new products that’ll, were gonna be announced at the site.

Uh, we’re already getting inundated with requests on the Weather Guard side. It’s insane. We’re telling people, like, “Slow down, slow down, slow down. We’ll, we’ll, we’ll talk to you about it when we get to Houston.” But, uh, expect a very attentive audience this year, which is exciting.
