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,

Allen Hall: Well, we're back with another edition of the Uptime Wind Energy podcast. I got Rosemary Barnes in Australia, Phil Totaro in Warm and sunny California, and Joel Saxon in practically hell in temperature in Austin, Texas. I was just down in Dallas, Texas a day ago, and man, is that hot. There's just like a, a certain kind of heat, you know, you need to get indoors pretty quick. Texas heat is really bad right now. Joel Saxum: You know, one thing I didn't know about this area out here west of Austin, like in the Hill country, it's actually really windy out here. Like there's a steady wind all the time that, and you don't hit [00:01:00] wind farms for another like three hours when you had West, like the first ones. But it's like, I lived in Houston and Texas and it was pretty dormant most of the time, but it, there's constant wind here as the temperatures change throughout the day. All the time explains all the wind turbines. Rosemary Barnes: Yeah, you sound like me when I moved to Denmark and I'm like, why do I have to live in this windy place? Allen Hall: So we have a birthday to celebrate and no, it's not Rosie's birthday. It's Nord Deck's birthday and it's celebrating their 40th anniversary and they've been around since 1985. And some facts about Nordex that they published really interesting. They have developed 46 different onshore turbine types. Across the two companies, which was Nordex, SE, and Acciona. And That's amazing. So in 40 years, did those two companies now merge together A couple of years ago? Uh, is they have 46 different onshore term designs from 250 kilowatts up to seven megawatt machines. Now Rosemary, I think this kind of high, [00:02:00] and congratulations to Nordex by the way. That's quite an achievement. It does highlight the rate of pace. For wind turbines from the mid eighties up till now. One new turbine a year is a lot. Rosemary Barnes: Yeah. And it's not the hugest company, right. It's not like they've got a hundred thousand employees developing those, uh, that one new turbine every year. So, yeah. Um. Nobody's been sitting around on their hands at that company. Joel Saxum: They made it past the, is it, isn't it the rule of thumb, Alan? We talk about businesses like in the states, like if you make it past five years, you're, you're good Allen Hall: al almost right? So most companies fail within the first year to three years. It's, it's hard to make it to three, then five, then 10. If you can make it across 10, you have something worthwhile. It's gonna stick around for a little bit. And, and Nordics has. Rosemary Barnes: What's weather guard at? Allen Hall: Uh, we're at. Almost 2020. Rosemary Barnes: Whew. An institution. Allen Hall: An institution. Yeah. We need to beat an institution at this point.

And subscribe to Rosemary Barnes' YouTube channel here. Have a question we can answer on the show? Email us! There's tension between the US and UK over Chinese wind energy investment. The US government has raised security concerns about plans by Chinese company Mingyang to build a wind turbine factory in Scotland. Trump administration officials warned the UK about what they call national security risks. The factory would supply wind farms in the North Sea. UK ministers are now reviewing whether to block the project. They're worried about cybersecurity and being too dependent on Chinese technology. Security officials say Chinese wind turbines could contain electronic surveillance equipment. Mingyang is not state-owned, but critics worry the Chinese government could interfere. Deputy First Minister Kate Forbes had said Scotland was open to the factory. But the Scottish Government is waiting for security guidance from Westminster. A UK Government spokesperson said they would never let anything threaten national security. All energy investments face the highest security checks. Construction has officially started on Belgium's major offshore energy project. Workers cut the first steel this week at a factory in the Netherlands. They're building parts for the Princess Elisabeth hub. The artificial island will sit twenty-eight miles off the Belgian coast. The project will transport at least two point one gigawatts of wind energy to the mainland. That's enough power for millions of homes. HSM Offshore Energy is making high-voltage equipment at their Schiedam yard. Commercial director Hans Leerdam says this marks a key moment for European energy security. The island will also connect Belgium to other European countries, including the UK. Final assembly will happen in Schiedam and Vlissingen. Leerdam calls it one of Europe's most strategic energy projects moving from plan to reality. The UK government has announced a massive boost for offshore wind energy. Great British Energy is leading a one billion pound investment package. The money will fund wind turbine manufacturing, floating platforms, and port upgrades. Three hundred million pounds comes from Great British Energy. The Crown Estate and private companies are adding another seven hundred million pounds. The investment targets key regions including Teesside, South Wales, East Anglia, and Scotland. Officials say it will create thousands of skilled jobs. The government is also offering up to five hundred forty-four million pounds through its Clean Industry Bonus. This encourages developers to invest in deprived areas. The North East of England could receive up to two hundred million pounds. That might unlock four billion pounds in private investment. Scotland gets up to one hundred eighty-five million pounds for ports and high-tech components. The offshore wind expansion should support fourteen thousand new jobs over four years. Industry leaders believe this could boost the UK economy by twenty-five billion pounds by twenty thirty-five. Turkey is planning a major expansion of its wind energy capacity. The country aims to reach forty-eight gigawatts of wind power by twenty thirty-five. Turkey currently has nearly fourteen gigawatts installed. That makes it the sixth largest wind power producer in Europe and twelfth in the world.

Wind Farm operators face mounting challenges from managing thousands of diverse turbines to navigating the energy markets and constant regulatory changes. This week we speak with Alejandro Cabrera Munoz, CEO, and founder of Green Eagle Solutions. Green Eagle's ARSOS platform gives control rooms immediate responses to turbine issues, which dramatically increases productivity and captures more revenue from their turbines. Welcome to Uptime Spotlight, shining Light on Wind. Energy's brightest innovators. This is the progress powering tomorrow. Allen Hall: Alejandro, welcome to the show. Speaker 3: Thank you, Allen. Thank you for having me here today. Allen Hall: so Green Eagle Solutions is in a unique space of the renewable energy marketplace, and you saw a problem several years ago, particularly in the control rooms of [00:01:00] wind operators. What is that problem that you identified? Speaker 3: Yeah, Allen, I think it, it's, It's a challenge that, most of our customers, which are generally large operators, are facing today. But it's a challenge that have been, growing, in the past years. So first of all, it's, it goes along with the penetration of renewables in the industry, right? So we have, due to all these many years of aggregating new wind farms and solar plants, We are seeing how the complexity, the technical complexity of operating and supervising these assets is growing exponentially, right? So we now have customers with thousands of wind turbines that have, different models, different versions of, controllers, And also different healthcare issues that they have to take care of. So the technical complexity is a fair, the first [00:02:00] factor that, it's has to be tackled from a control room, And, makes, operations quite, challenging. Along with this, we have market volatility. So in the recent years especially, we are seeing how, Negative pricing and optional markets are now affecting operations in a daily, basis. Basically in every 15 minutes you dunno if you're gonna produce or not. Up until recently it was as simple as if you had wind resource, you would produce energy from wind farms. If you had solar, you produce energy from solar plants. It's not like that anymore. So the market is quite, volatile. that adds a lot of complexity from the commercial point of view of, Of the assets. And the last, factor that is actually becoming, an increasing challenge for everyone is the regulatory changes. So basically due to the penetration of renewable energies, what we see is that all governments, all grid operators and our market operators are constantly issuing [00:03:00] new adapt, new regulatory changes, that everyone has to adapt to no matter what. it doesn't matter if you have an all wind farm or a newer wind farm. Or you prepared or not, like everyone has to be adapted to, to the new regulatory, changes. the three things are actually affecting, our customers and we are trying to solve all these issues, the way, the, best way that we can, right? So most of our customers, we just have a control room full of people. they will do their best effort to accommodate these challenges. The reality is that we have to.

So if you haven't met Tom, you need to go to this webinar and find out what's going on. And Michael McQueenie from SkySpecs. It's the rule. Subject is when should you be scheduling your drone inspections and you shouldn't be doing it in the spring. That's really important. If you wanna save some money on your operational aspects, your [00:01:00] o and m budget, you need to be thinking about how to get your inspections done, when to get your inspections done, and what tools are available to you at different times a year. So there's optimal times to get your drones inspected and there's suboptimal times. Suboptimal times is like March. Don't do it, then do it the previous fall. and so Joel will be there. I will be there. Don't miss it. It is June 25th. 11:00 AM and you can sign up in the show notes below.

I have Joel Saxo along and Rosemary Barnes from Australia and I've. Just been digging through all the news over the last several days. Really disappointing news to the United States, but over [00:02:00] in China. TRRC has unveiled a 20 megawatt floating wind turbine, and it's, has a rotor diameter of 260 meters, which is not really outrageous. The CRRC press release, which is a little outrageous, let, me read you some of this, and it's called The Key Hung. wind turbine, the key Hung, integrates multiple innovative control technologies offering four core advantages. High intelligence system, modularization, full chain collaboration. And Joel, don't we all want that? And exceptional stability. It incorporates various intelligent controls, sensing and detection technologies that design further enhances the unit's flexibility and efficiency by modularizing key system interfaces and structural components. So there are a lot of words in this press release, but they don't say, actually say anything at all. So that's why we have Rosemary here to suss Joel Saxum: out. Allen Hall: What is happening with CRRC and a [00:03:00] 20 megawatt floating turbine? Is it really needed, Rosemary? Rosemary Barnes: Yeah, I think I've made my thoughts clear about the, like bigger, kind of pursuit of, offshore wind turbines.

The Independent Planning Commission in New South Wales has approved ACEN Australia's nine hundred forty-three megawatt Valley of the Winds wind farm. The project also includes a three hundred twenty megawatt battery storage system. The project will create up to four hundred construction jobs and fifty permanent positions. The investment is approximately one point six eight billion Australian dollars. The island nation of Bermuda is making the most of its windy weather. Officials unveiled plans for an offshore wind farm starting with seventeen turbines by twenty twenty-seven. The project aims to help Bermuda reach its twenty thirty-five goal of eighty-five percent renewable energy. The project will begin with a sixty megawatt installation near the north shore. Officials hope to scale up to one hundred twenty megawatts total. Nigel Burgess, head of regulation at Regulatory Authority Bermuda, calls offshore wind a compelling opportunity. The project will lower exposure to fuel price shocks and create space for long-term investment. Currently, Bermuda gets one hundred percent of its power from fuel burning. The project aims to promote energy independence by reducing dependence on imported fuels. The wind farm is expected to be operational by twenty thirty. Nova Scotia has announced an ambitious offshore wind project that could cost up to ten billion dollars. Premier Tim Houston wants to license enough offshore turbines over the next ten years to produce forty gigawatts of electricity. That's eight times more than originally planned. To put this in perspective, Nova Scotia with just over one million people requires only two point four gigawatts at peak demand. China's offshore wind turbines were producing just under forty-two gigawatts as of last year. The project would require hundreds of wind turbines built in water about one hundred meters deep, about twenty-five kilometers offshore. Experts say the project would actually need more than four thousand offshore turbines using current fifteen megawatt turbines. The transmission line alone is estimated to cost between five billion and ten billion dollars to connect the wind farms with the rest of the country. The premier calls it a concept to capture the imagination of Nova Scotians. He wants federal help to cover costs, saying the excess electricity could supply twenty-seven percent of Canada's total demand.

This is the Progress Powering tomorrow. Allen Hall: Howard, welcome back to the show. Thank you. Well, we've been traveling a, a good deal and talking to a lot of operators in the United States and in Europe, and even in Australia. And, uh, your name comes up quite a bit because we talk to all the technical people in the world and we see a lot of things. And I get asked quite a bit, what is the coolest technology that I don't know about? And I say, Howard Penrose MotorDoc. And they say, who? And I say, well, wait a minute. If you want something super powerful to learn about your turbine, that is easy to implement and has been vetted and has years of in-service testing and verification. It is MotorDock, it is [00:01:00] empower for motors, it is empath for systems and vibration and all the other things. And now empath, CMS, which is a continuous monitoring system that you're offering that those systems are revolutionary and I don't use that word a lot in wind. It's revolutionary in wind and. Let, let me just back up a little bit because I, I want to explain what some of these problems are that we're seeing in the field and, and what your systems do. But there's a, the, the core to what your technology is, is that you're using the air gap between the rotor and the stator and the generator to monitor what's happening inside the turbine. Very precisely. Can you just provide a little insight like how that magic happens? Howard Penrose: Okay. It's, it's basically, we use it as an, as a basic accelerometer. So, um, the side to side movement of the, of the rotor inside the air gap. Um. I could get very technical and use the word [00:02:00] inverse square law, but basically in the magnetic field I've got side to side movement. Plus every defect in the powertrain, um, causes either blips or hesitations in the rotation. Basically, the torque of the machine, which is also picked up in the air gap, and from a physics standpoint. The air gap, the magnetic field, can't tell the difference. And, um, both voltage and current see that as small ripples in the wave form, and then we just pull that data out. So, um, uh, I, I liken it exactly as vibration. Just a different approach, Allen Hall: right? And that that vibration turns into little ripples. And then I'm gonna talk electrical engineering, just for a brief moment, everybody. We're taking it from the time domain to the frequency domain. We're doing a four a transform. And in that four a transform, you can see these spikes that occur at, uh, known locations that correlate back to what the machine is doing Howard Penrose: exactly. [00:03:00] They're they're exact calculations, uh, down to the hundred or even thousandths of a hertz. Uh, so, uh, when we, when we do the measurements, they come up as side bands around, uh, whatever. The, the, uh, signature is, so the amplitude modulation, it's an amplitude modulated signal. So I have, uh, basically the ripple show up on the positive side of the waveform and on the negative side of the waveform. So around everything, I just have plus and minus line frequency. That's, that's basically the primary difference. Then we just convert it over to decibels, which makes it, um, relational to the load,
