Welcome to Uptime Spotlight, shining light on wind. Energy’s brightest innovators. This is the Progress Powering Tomorrow.

Alright, we’re here in Phoenix, a CP, clean power, uh, 2025. So I’m, uh. Sitting with Antoine Larvol from, he’s a CTO from Windar. Yep. Welcome to the show. Thank you. Uh, we’ve been, uh, happy enough to get actually to sit inside your booth where it’s nice and qui. Quiet and isn’t it nice? Yeah. We got glass behind the camera here and people are walking by, walking by, walking by.

Um, so this morning, uh, we, we talked yesterday a little bit about what wind photonics does. Yep. Of course, from our, uh, some of our other friends around the world. We’ve heard about some, some campaigns you’ve done in the United States, which have been. Really successful. So yeah, congrat good. Congratulations there.

Yeah, thank you. Um, and, and as, as a lot of things in the wind industry, Windar, photonics based in Denmark.

Antoine Larvol: Yeah.

Joel Saxum: So you guys, uh, bring it, bring in that Danish [00:01:00]technology. We’re here, of course, bringing it to the US market at a CP, the American Clean Power Show. So welcome to the States. Thank you. Um, it’s a short one, but a

Antoine Larvol: good one.

Yeah, yeah, yeah,

Joel Saxum: exactly. So, so I want to talk a little bit about what Windar photonics and, and it is a LIDAR based sensor, correct?

Antoine Larvol: Yes. Right. So. We do continuous wave base, uh, lidar. Yep. Uh, main product is a two beam version mm-hmm. Where you shoot, uh, at 80 meters in front of the turbine. Mm-hmm. And you basically alternate from one beam to the other.

And measure wind speed and direction upfront, the, the turbine among others.

Joel Saxum: Right. So we’re talking about, uh, if you, if you’re in the wind industry, you’ve ever seen these lidar units that are put actually, you’re the cell mounted, correct? Yes. Okay. Yeah. So, and, and, uh, we’re looking more on the optimization, retrofit monitoring side of things.

Yeah,

Antoine Larvol: exactly. So we’ve never been a resource assessment company. Yeah. Or we don’t look at power curve verification and stuff like that. We really [00:02:00] focus on. Retrofitting those, existing turbines. And then add value to In terms of information to, the customer, Yeah. With the mon monitoring side of things.

Yeah. And, from day one, that’s been the goal of Windar Making something cheap, robust. That can just stay there and measure with good availability, wind speed, and direction coming to your turbine.

Joel Saxum: I love it. so we wanna squeeze as much as we can outta these turbines. And you guys are increasing AEP that’s, the name of the game.

Yeah. Right.

Increasing AEP below rated. and then above rated you decrease loads. Increase uptime. and we basically do that by going on the line of the wind direction. that you then feed to the turbine controller and then we can actually adjust the, yaw position of the turbine according to our information.

So I want to talk a little bit, we, we chatted a little bit offline about the, technology behind it, right? Yep. And people in the wind industry, if you’re around the wind industry around resourcing or you’re around optimization, you’ve heard [00:03:00] lidar. Yep. You know what I mean? And, but I don’t think.

A lot of people know exactly what lidar, what it does, how it does it. Yeah. What is the technical, where’s the magic coming from? Exactly. It’s just a black box. It’s just a, technically, I guess it’s just a white box. Yeah. For the wind photonics. But how do, how does the lidar work to measure actual wind speed coming into the turbine?

Antoine Larvol: Yeah,

Joel Saxum: so

Antoine Larvol: we basically focus laser light, and we do a focus point at 80 meters in front of the turbine. And basically there where your light concentrates on a specific location, then you hit particles in the air, pollen, water droplets, dust, whatever. Dust. Yeah. Okay. Whatever is there. And then you will, have a certain frequency of the light you emit, and that will just bounce on those particles and come back with a slight shift in frequency.

And that’s doppler shift. And then. Analyzing this shift, then you can derive a wind speed along the beam Of, the, [00:04:00] lidar.

Joel Saxum: So

Antoine Larvol: we’re

Joel Saxum: talking about like a bunch of really, really smart trigonometry kind of

Antoine Larvol: Yeah, exactly. I mean, you have a bit of optics. Yeah. Trigonometry. Uh, and, uh, yeah, it’s a bunch of optics.

Hardware, uh, software. A lot of software. A lot of software, yeah. Uh, to analyze that and squeeze as much info out of this. Right. We do, uh, you can derive wind speed, wind direction. You can look at turbulence. Mm-hmm. You can, uh, detect our wake, uh, is going on. So you can actually detect whether or not your turbine is in the wake.

Uh, and then based on that, then you will do different ing strategy in order to make the most of your turbine. Right. Decrease loads or increase, uh, outputs.

Joel Saxum: Yeah. So and mean. That’s what, uh, the uptime podcast we’re here about. When we bring technology, we talk to. Smart people like yourself, Antoine. Thank you.

We, we want to pick the, pick out the solutions, right? Like what, how are you guys helping the wind industry? And that’s the important thing here. So we’ve [00:05:00] talked about two, basically, kind of two tracks that you guys go down and one of ’em is optimization. Yep. And one of ’em is monitoring.

Antoine Larvol: Yep.

Joel Saxum: So let’s, let’s start with optimization.

What does that look like from wind?

Antoine Larvol: Yeah, I mean that’s a bit the unique part of wind. Uh, so we do lidar, uh, but actually the. Like this good selling product is this, uh, wind technology. So basically what it does is that we go on the line of the wind direction, uh, of the sensors from the primary secondary sensor from the turbine, and then we go on that line, read this info that they are measuring, and then, uh, correct this info according to our measurements.

Ah, okay. What’s going on out there is that, you know, those, uh, devices are placed behind the rotr. So they’re basically, uh, biased by the blades, basically turning in front and creating a lot of turbulence. You also, you have some effects depending on the, your misalignment of the turbine. And so basically you don’t have a great [00:06:00] measurement from, from those devices.

So what we bring is that, right. We measure upfront, so we are unbiased and then modify, the information, the wind direction information, and then feed that to the turbine controller so we can actually, yo. The turbine the way we want.

Joel Saxum: So in a really simple way, you guys are creating what is an amazing wind speed and direction sensor.

Antoine Larvol: Yeah. So for this WindTIMIZER we only use wind direction information. And then basically improve what the turbine is given as information about. Relative wind direction of the nacelle Right. So yaw error. and then we correct that. So we increase, energy production below rated wind speed.

And then we have different strategies above rated wind speeds, aiming at reducing loads and increasing uptime. So the way we do that is actually we introduce small yaw misalignment, depending on wind [00:07:00] speed, in order to achieve that. Especially decreased loads on, blades.

Yeah. and the drive train rate.

Joel Saxum: So in, let’s, talk a case study, right? We wanna, we always want to give examples, right? Yeah. So, so in the states we had, we talked about you guys are focusing on more, well not globally really, but you’re focusing on more of like the last generation of turbines, not the brand new ones.

Antoine Larvol: Yeah. So we are like really focusing at the moment on all this generation of. G 1, 15, 16. Two three. Yeah. 87 97 V 80, V 82. V 90, uh, seven, uh, maybe 2 92. Okay. Like this kind of turbines. Yeah. Uh, that’s been not there for, for a while. And basically where you don’t have a lot of offering on how to squeeze more power.

And they’re not supported anymore by manufacturers, right? Yeah. Uh, so that’s where we come in and offer that to. To be able [00:08:00] to, to produce more power, decrease load. Right. So the way we do that, usually when, uh, a new customer approach us is that you will do a deployment of like five units in a, in the farm.

Mm-hmm. Uh, basically pick randomly, uh, if, uh, five turbines and then we will install, uh, technology. You install like in three, four hours you’re done with installing the system. Oh, nice. On the tripod. Uh, wire that to the turbine controller. And then, uh, you will start this toggling campaign. So what we do is that we turn on the technology for 70 minutes and then turn it off 70 minutes.

This way you have a slight shift over of the period over the day. Mm-hmm. So you don’t always hit exactly the same time. So in case there’s, you know, any effect, recurring effect, and you go away from that, and then you will do this toggling on and off for like a period of like three, four months, depending on wind conditions.

And once you have like enough data on every wind, wind. You will analyze, uh, [00:09:00] what’s the power production difference when the union, the system is on versus off. Right. Okay. And then, um, yeah, compare that. Hopefully you gain some power. Yeah, yeah. Yeah. I mean, we know that those turbine out there, uh, actually, uh, arm is aligned, right?

So we know what to expect. I mean, we, uh, we did exactly that for some, uh, customers with, uh, V 80 twos. Mm-hmm. Uh, and you usually find like six and a half degree, uh, average. Oh, wow. Uh, your misalignment Wow. That you then correcting it, you, you reach like two, seven, 3%. Yeah. AP gain and uh, and that’s, so what we’ve done a while back with some customer, they verified the data.

We did our report at the time Vest was distributing for us. Mm-hmm. So they also did the report. We will agree. That was within 2.73% AP gain, man, I think. Yeah. And then they went to, to roll out the farm. Right.

Joel Saxum: Wow. So they rolled out the whole farm after getting the two. Yeah. Well of course you would. Right.

That [00:10:00] that’s the business case. That makes sense.

Antoine Larvol: I mean, you actually prove that you gained something. Yeah. So, hey, go

Joel Saxum: for it. Right. So if I’m sitting on a V, you know, like if I’m just gonna run with that example of V 82, those are mostly probably installed. 2000 man, 2000, five to 2000 around that. Yeah. 10 ish.

So I’ve been, I’ve owned a wind farm. Say I’m in the States, I’ve owned a wind farm for. 10, 15, 20 years for whatever reason, I haven’t repowered it or whatnot. And all of a sudden someone comes along and says, I can get you two and a half, 3% more a EP.

Antoine Larvol: Yeah. I mean, we are rolling out all those farms at the moment, right?

Yeah. I think we are on 60, 70% of the whole fleet in the US at the moment. Yeah. Yeah.

Joel Saxum: I’m jumping on that if that’s me. Yeah. Um, you know, we had talked, like I said, off air. You guys have over a thousand units out. Yeah. But just in the last year, your, your deployments have ramped up big.

Antoine Larvol: Yeah, we did like more than 500 I think last year.

Wow. I think we are doubling that this year. Yeah.

Joel Saxum: Uh,

Antoine Larvol: so

Joel Saxum: good

Antoine Larvol: for you guys. Yeah, it’s going great, doing

Joel Saxum: big things for the industry. I like it. Um, so yeah, I guess we’ll for that moment if you have a V 82 wind farm or something Yeah. We

Antoine Larvol: probably [00:11:00] contacted you already. Yeah.

Joel Saxum: Yeah. Give these guys a call back.

Uh, ’cause they’re gonna get you more power and, uh, more revenue. I guess it’s at the end of the day. So optimization, you’re, you’re adjusting ya, you’re, you’re correcting for loads. You’re, you’re fixing some of these things, but there’s also a monitoring piece to this.

Antoine Larvol: Yeah. So that actually came, uh, from those rollouts we did.

Um, there’s like some security concerns when you go and actually install those hundreds of units on the farm. That’s, that’s huge in the United States. Anything you’re putting on right now? Exactly. Cybersecurity. Cybersecurity. So toing campaign, we, we usually do modems. Uh, 3G uh, modem connected to the. To the unit, but that doesn’t fly when you do rollouts.

Right? So what we did, uh, is actually then package all our monitoring tool, reporting tool data, graving tool and processing, uh, all kind of, uh, alarm flags in case like something goes wrong with any of those units. So we packaged all this into a an [00:12:00] os. Mm-hmm. Uh, and then we can directly deploy that on customer servers.

And then this way they can monitor the lighter fleet. Mm-hmm. Uh, real time and then generate reports, uh, and see that basically those units are, are running fine. Right? Yeah, yeah. Everything on, on premise so that it’s not Yeah, exactly. You’re not worrying. Exactly. So we don’t have access to it. Uh, it’s fuel integrated, integrated in the network, and we just hands off Yeah.

Let the unit run, you know? Yeah. Uh, and then as part of that. Then we also developed some new modules that we produce, uh, we propose to the customer and, uh, yeah, one of them, for example, is this, uh, turbine performance monitoring module where, you know, we have very good wind speed data. Uh, we can actually measure also, uh, rotation, rotational, uh, rotational speed of the turbine.

And then, uh, mixing those two, having air density. Then you can actually track performance of, of the turbine over time. Okay. Uh, within [00:13:00] plus, minus 0.5%. Wow. Um, and then, yeah, that’s basically that. Right. You will see then, uh, whether, you know, you have some kind of leading edge degradation Yeah. On certain specific units.

And then we are looking into, you know, looking at turbines individually, but eventually. In some mirror, whatever. Uh, look at turbines like once against the other as well. Yeah. Um, we integrating, uh, some rotor balance detection, for example. Okay. Uh, so we just trying to add more and more value to the customer so that they have a proper view of the asset.

Right. Yeah. Usually what we see that people do in the industry is that, you know, they look at scada, right? Yeah. That’s what you have, that’s what you can do. Uh, so. You do power curve assessment and whatnot with your scada, so you believe in this wind speed, wind direction from those an anemometers. Mm-hmm.

But we know by experience that that’s not accurate. Right? Right. So you might end up making, [00:14:00] um, wrong decision because you’re just given wrong information. Right. And you have companies out there, you know, they’re doing ai, machine learning, modeling, whatever. Great. But. You know, if the data is wrong, uh, yeah, you can do whatever you want.

You will reach wrong conclusions, right? Yeah. Uh, so that’s what we bring value. We actually have the. The proper wind speed so we can do properly the monitoring. Right.

Joel Saxum: Uh, what are the, the saying, the old saying comes to mind for me? Like, you can’t make chicken soup out of chicken poop. Right. So if you, something like that.

So if you don’t have good data coming in, sometimes all the, all the AI models in the world and things, you can make

Antoine Larvol: great modeling, whatever. Yeah. But it may not be true. Right? Yeah.

Joel Saxum: And I don’t wanna to, I don’t wanna like stop that idea ’cause I think it’s great as we move forward. No, no. I mean, we have nothing

Antoine Larvol: against the idea.

Joel Saxum: It is just.

Antoine Larvol: You know, you’re using wrong info, right? Yeah. So you’re gonna

Joel Saxum: lead to wrong conclusions and that’s it. Right? So in my mind, I’m thinking about another, another use case for the window, like the windows, the monitoring portion of it. And it is, you talk to all of these [00:15:00] people about when you, when you mentioned erosion monitoring for per performance.

When you talk to all these people about, uh, what’s the performance degradation of, of this erosion happening on the leading edge or. If we put LEP on, do we get this performance back and stuff? And I’m thinking, I’m, I’m talking to all the researchers that are listening to this. You guys should be using your sensors to validate a lot of this research that’s going on, on these wind turbines.

Yeah. I mean, you, you track,

Antoine Larvol: I mean, since you have the LIDAR out there anyway, you know, yeah. You might as well use the data and then track properly how your asset is doing over time. Right. Um. And that’s the whole idea, right? Squeezing most information from Yep. What we have, right? Yep. And you know, we know turbulence, uh, conditions.

We know wind speed. We know, uh, wake, whether it’s wake or not. Mm-hmm. We know air density. We just mm-hmm. Put some module there and then you can just basically track then your performance over time. Right? Yeah. Uh, and then have this done [00:16:00] automatically. Mm-hmm. Uh, and then I just have, go check a dashboard.

And be like, okay, past six months, how has this turbine been doing? Mm-hmm. Okay, great. You just stay nice and clean and then suddenly you can pinpoint and target exactly the one that goes wrong in the farm. Right? Yeah. And then, I mean, we are not going to fix your leading edge erosion. Right. You still need to have, go out there, repair it yourself, right?

Yeah. But at least we can point out Okay. There’s a problem there. Right? Yeah.

Joel Saxum: You know, and one of the things I wanna make sure we touch on is we brushed past the cybersecurity thing. Yeah. Talking with all of the asset owners that I deal with every day, friends in the industry, CMS companies, you name it.

Cybersecurity is becoming more and more of a frontline issue within the wind industry. Yep. Everybody’s concerned about it. Anything you try to put on a turbine, especially if it’s connected to a controller, connected to electronics, it’s over the air, it’s on the cloud. Everybody’s ah, everybody has their hair up on the back of their neck about it.

So you guys have taken the risk [00:17:00] out of that thing. By putting everything on premise. Yeah. I

Antoine Larvol: mean we, we’ve, it’s our own tools. yeah. At window we always develop our own tools in the house. we have a great software team doing that, and, and then they basically package the just stuff we’ve been developing for the past 10 years.

Yeah. Into an OS and that you can just deploy at the customer. And then this way you have like automatic reporting about your lidars. your turbines. You can, directly interact with those lidars, turn them on, turn them off, start those towing campaign, get some, information about how much AP you gained, stuff like that.

Joel Saxum: Fantastic.

Antoine Larvol: Yeah.

Joel Saxum: so message that I want to get out to the wind industry, if you, have some turbines that are legacy turbines that are out there. And you wanna get two point a half to 3% more revenue generated outta those turbines. Yep. You need to call wind photographers and a bit more time, I mean, less loads.

Yeah, less [00:18:00] loads. Extend the life of those blades. I mean, we know that those

Antoine Larvol: turbines are, have some issues. Right. So it’s, uh, it’s pretty straightforward to make a business case. Right. Fantastic. So Antoine, how do people get ahold of you? Uh, we have a website. We are online. We are on LinkedIn. Okay. Uh, so yeah, you just go on the window, photonics.com and, uh.

And then reach out to us. Right. Fantastic.

Joel Saxum: Well, Antoine, thanks for, uh, joining the Uptime podcast here. Thanks a lot again, live here from, uh, in Phoenix. It’s hot outside, so let’s stay inside. Yes, and I’d read it. Yeah. 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.
