Allen Hall: Welcome to the special edition of the Uptime Wind Energy Podcast. I’m your host, Allen Hall, and I’m here with my co host, Joel Saxum. And we brought along a friend, Lars Bendsen of AC883. We’re still in San Diego, so we’re a long way from Canada, where AC883 is based. Lars is always full of information about what’s happening in the wind industry and what’s happening on the repair side and the technology side.
Because he’s been involved in wind since the dawn of wind, pretty much. Lars, welcome back to the program. Thank you. So there’s a whole bunch of things going on right now. We’re at ACP OMS. We’ve been together all week. You had a ton of traffic to your booth. A lot of customers trying to sign up for repairs this season and learn about all the new technology that’s going on.
You want to just talk to what you’re seeing?
Lars Bendsen: Yeah, I’ll try to do that. Thank you for having me on. We we seem to be getting busy. Yeah. There’s a ton of interest for our blade program, which differs clearly from the rest of our good colleagues, the way we’re approaching it. Yeah. We are building a new website because we have so many offerings now.
We need to be more, we need to be more clear in our communication.
Joel Saxum: Confirmed new website. We just confirmed it.
Lars Bendsen: Confirmed, Yeah. And AC83, that name will remain, but it could be the set AC83 wind repair, wind whatever something. We’re going to rebrand that a little bit because it can be a bit confusing.
Okay. Because we have so many offering in. As an ISP part, but also as a new technology provider, which is the DNA of the company. That’s how we started.
Joel Saxum: Right, so let’s talk blade repair real quick. You guys it’s mid February right now. Usually when we start to see tenders come out from the big operators or even smaller operators, they come out in November and December if they’re on the ball.
Yeah. If they’re on the ball because you want to get your blade repair, basically capacity ready for that next season, because there’s, we all know there’s a limited amount of it capacity in the Yeah. And in Canada, your season’s really short, so you’re like end of May to mid October.
Lars Bendsen: Maybe It is mid May to worst case scenario end of October.
Yeah. Yeah. But yeah, people want have us out of the door and end of September if they can.
Joel Saxum: Yeah. So if you, if the, so what it looks like right now, are you see, did you see a lot of tenders come through in the Canadian market?
Lars Bendsen: There’s a ton of ten, not, there’s a ton of rough cues out there, but it seems like the decision has not really been made.
Hasn’t been made yet? Some have not. And a bit of a mystery to us, why it’s dragging out. We know our colleagues have not gotten it either, it’s not because we haven’t gotten the work. Yeah. It simply hasn’t been awarded.
Joel Saxum: Yeah. Which is odd, because it’s like, we’re coming on the end of February, so there’s really only You know, two months to get ready to get those technicians suited up and booted up and ready to go.
Lars Bendsen: Yeah, normally you can say that technician who is available in June in Canada, we do not want to have him. There’s a reason why I don’t have a job in June. Yeah. So therefore, there’s really fighting for the good resources. Yep. We have built our division up a little bit different because the season only is for five months.
Yeah. So we have a combination of Canadian crews. It’s a little base crew. We have all our management, of course, product management, quality, all the job. We own the project, but we have a staff coming in from Europe with, of course, adequate work permit and all that jazz. They’re all GVO trained and we’re only working with our rather certified manpower companies.
So we do the quality control and we’re exactly what we’re getting. That means we have qualified. 10 years from day one, where our good colleagues that has their own employees, we let them go end of November and then had them back in May and 50 percent not coming back. They’re starting up with a carpenter.
He’s not afraid of heights, so he can work in ropes. That’s, I think that’s our advantage that we are building. We try to build our teams to the scope we are getting. The flip side of that is we need a little bit more prep time. Yep. Yep. Because we want them to show they have the adequate, certificates when I have the best of the people, and we also make sure we get the work permit. It just takes time. And it’s out of those guys. They’re really in, in it’s all, it’s a global thing that there’s simply not technicians enough. So if we don’t assign them now, they go somewhere else.
Joel Saxum: Yeah. So these RFQs that are sitting out there, they need to be let soon. They have to give somebody a job
Lars Bendsen: at a certain point.
Yeah. And that’s not only us. I think that’s a cross to you. Yeah that’s my two cents.
Allen Hall: Because AC883 doesn’t do work just in Canada. You’re doing it all over North America.
Lars Bendsen: You do it all over North America, but that also get the work company into us. It’s not necessarily easier than this to get into Canada. That’s true. It’s just a process in time, right?
Allen Hall: Yeah. And then you got to get organized. And I know one of the discussions I heard on the floor this week was essentially power loss because you’re not sure where your turbine is pointed.
And. My first thought was Lars knows. Yeah. He’s probably one of the few that can actually find out. The complaint we’re hearing is we’re not generating enough power. Is it the wind resource? We had an engineer come up talking about wind resources. Or is it the turbine themselves? And I think it’s maybe a combination of both.
But we ought to be able to eliminate the pitch angle of the blades and the yaw. Yeah. And point the thing in the right direction. It seems like the simple thing. You would think. But it’s not easy to do, actually.
Lars Bendsen: No, but it’s interesting. Again, I think we spoke about it a few times. The new technology, 90 percent of it is coming from Europe.
Yeah. Oh, sure. That’s the nature of the beast. Because that’s where the fire started.
Yeah. That’s how it is, right? And now we’re here in the ACP and just the Danish booth on the Hamburg exhibition is bigger than this complete exhibition. Oh, yeah. Yeah.
Joel Saxum: In Hamburg, it’s other 100 some odd companies.
110 Danish exhibitors last year.
Lars Bendsen: Yeah. So just to give a perspective. Yeah. And there’s all new technology coming out. It’s coming out there. There are a few coming out of North America. One of them is here. But I’m just saying that. 90 percent is coming out of Europe, that’s just a fact. And so the whole control philosophy and the accurate alignment of turbines is also coming out of the German world or the Danish world.
The DTU, the number of spin offs of DTU into the wind industry is crazy, insane.
Allen Hall: And that, that ability that AC883 has to go off and look at pitch alignment without touching the turbine, right? It’s all crazy. Lasers and magic. Yeah, it’s lasers. Lasers and magic. Lasers and magic.
Lars Bendsen: Lasers and magic.
That’s the new website. That’s what we do. No, we’re back to, to the saying I started I think last year I said the rotor is the motor.
Allen Hall: Yeah. Rotor is the motor.
Lars Bendsen: And as everybody is talking about, gearbox is not yes, if a rotor is not aligned, It could be on the pits. It could be on. on the yaw, whatever, if that’s not aligned, or you have leading edge erosion, then of course the turbine is not performing.
Then you start talking about gearbox, it doesn’t really matter. The trouble starts at the root, because it comes from the rotor, in nine out of ten times.
Allen Hall: So that leads into the question about LiDAR. Yeah. Because there’s more discussions, you read through the magazines, go online, there’s a lot of new LiDAR systems that are out there.
But you’ve actually applied LIDAR to some particular OEM turbines that needed help. They weren’t pointed in the right direction. You want to explain like how that, what that is and how it works?
Lars Bendsen: It’s interesting because just to briefly touch on the pitch. I talked to some people, oh, it’s a new technology.
No, the system is actually 15 years old in Germany, but it’s new here. And on the LIDAR system, the cell based LIDAR, we introduced it in 2014. Yeah, it’s not new. It’s just new here. Yeah, it’s been in China for the last 10 years It’s proven but even China’s ahead of the curve that we are here.
Sure. So but also in all fairness in 2014 I call it a green banana Might be not a hundred percent developed. Now the banana have, mature to be a yellow banana. So it’s working now. And I’ve been through that painful process.
Joel Saxum: So they don’t follow the TRL scale. No. Zero to nine technology readiness.
It’s how green is the banana?
Lars Bendsen: But I had hair when I started this show.
Yeah, it’s been a learning curve. It’s been good. And now they know what’s running, been rolled out. to more than 200 turbines in Canada. Oh, wow. And it turns out that one of the specifics, it works on all stall regulated, pitch regulated, but it seems like the older stall regulated turbines have a problem really being well aligned towards the wind.
And that’s one issue they have. The other, there’s a natural, there’s a cell transfer function that means the true wind speed that the light is measuring 80 meters in front of the turbine. Okay. That’s the true wind speed. It’s not the same on the anemometer. The back of the nacelle. It’s actually, it’s always hunting the wind because it registered wind after it happened.
And it’s in a, what do you call it, in a not clean air flow. Yeah, it’s dirty back there. Yeah so that’s one of the issues. Another issue that turns out, there was also a steep learning curve, that the stall regulator, once they hit the rated wind speeds, they can actually get more alarms. So I can’t remember what the alarm code is called, but I get more alarms when you hit the rated wind speed when you’re 100 percent aligned.
So what we do above rated wind speed, we actually misalign it one or two degrees. And then we get less alarms on the turbine and we take the loads off the tower. Sure. By misaligning it above wind speed. It’s not logic. It was only by trying it so many times that misaligned it one or two degrees. Once you get above rated wind speeds, but the ramping up, you want to align as precise as we can.
Once over, we we switch to avoid the overspeed and then we are misaligning a little bit. And that’s with stall regulated turbines. That’s all regular turbines. Okay. Okay. It’s not the same on a pistol regulator. It’s just a regular, we want to make sure that we have a accurate angle towards the wind.
We want to be that as close to zero as possible. So in a Lehman’s way, you can say we have a better average. Because it’s all based on average. The same with the anemometer behind. It’s also based on average for the mid wing. We just have a more precise average. Because now we have two lasers, plus or minus 30 degrees coming out.
We compare the angles, and that way we get the correct the correct turbine angle.
Allen Hall: So if you’ve proven now the technology on the pitch the Stall regulator. Stall regulator turbines. Yeah. That seems and we vetted the thing, it’s now a fully ripe banana. Or does that mean this is going to come into the United States?
And a lot, because there’s a lot of little wind farms. You can just drive around Texas. You can point to the turbines that aren’t pointed in the right direction.
Lars Bendsen: I’ve been to wind farms where literally you can see driving by it as 30 degree difference. Yeah. Yeah. And I don’t get it, but seems until you don’t do anything, seems they don’t do it.
You can see it with your eye just driving by. Yeah. The anemometer is the worst.
Joel Saxum: That information’s back in the remote operation center too. Yeah. Someone’s looking at it.
Allen Hall: So what does that mean then? Is that mean that the industry as a whole, which is relying on anemometers, which is not a great measurement and it’s in dirty air and they apply a lot of.
Averaging to it because they don’t want the turbine hunting and pecking all the time Because that just wears and tears on the turbine. Yeah, because they don’t have something very accurate So is the move then to go to something like a LiDAR system? Even if it’s like one every other a turbine or one every five turbines.
I’ve heard some operators talking about that. Is that the move?
Lars Bendsen: I think it’s a matter of the turbine age and also The PPA you have? Sure, because there’s an ROI on it. On the on the installer c it’s depending on your PPA it’s about 3% power. Whoa. That’s a lot. 3% power for an investment on, I’m just saying between 15 and $20,000.
That’s all, that’s what those, that’s all it cost. Okay. That’s, so they are less than I thought. And it takes an hour to install, so it’s not a big.
And you can either do that. The problem is to get them into the, to the Wi Fi system on the turbine. Sure. And no one had that. So we actually installed it at the SIM card and it goes straight to Denmark.
We don’t even touch, we don’t even need to touch the.
Joel Saxum: So you’re not even touching the electrical system.
Lars Bendsen: Just need power. That’s it. That’s easy.
Joel Saxum: Yeah. Because that’s always a big thing when it comes to control systems or sensors or whatever is cybersecurity with wind turbines. Nobody wants to really.
Lars Bendsen: People freaks out just on it. Can we get access to your internet on the turbine? People start freaking out already then. Yeah. Some customers now, we are potentially going to install in U. S., fingers crossed this year on quite a few turbines. So it’s coming also on the solar turbines in the U.
S. Wow. For Canada, Canada has more than 200. Installed.
Allen Hall: That’s amazing. Okay.
Lars Bendsen: But also think it, so back to, so I go back to the PPA and the lifetime of the turbines, right? Because we are turbines are getting know a hundred dollars or more from megawatt. Yeah. That’s easy to justify right? Where go down on the spot market in Texas get 20, $20 megawatts and the turbine is 16 years old.
It’s a harder, it’s a harder sell or a harder business case to make.
Joel Saxum: If you think about this too that LiDAR system can go, if there’s a, if there’s a repower situation, whatever, you can pop it off, put it on the new one.
Lars Bendsen: We are on projects now, what is it called, repower, IRA? IRA. Yeah. We are on already and verified there.
One of our clients got us in there. So they are doing a power upgrade. Yeah. And putting a LiDAR on. Wow. It’s there. So we are in that ballpark. But there’s a lot of, there’s so much noise on the, so much noise on the communication again. Sure. Because there’s all control systems, they can do better.
There’s three control systems down there, retrofit controllers, and they claim they can do it. Yeah. And I can’t say if they can or not. There’s a lot of noise on the communication line. But it, the wind vane is the wind vane. So you can’t change that. Yeah. So that wouldn’t solve the other thing.
You’d have might be have better, your algorithms. that there’s on the controller today. But I, I can’t tell if I don’t think they can gain the same. And then you’re also back. Now we are trusting people’s turbines, trusting people’s controllers. And now it’s a harder sell all of a sudden.
Now there’s more to have a say.
Allen Hall: Yeah, sure. But with any sort of newish technology, it’s just because it’s not being deployed yet. as widely as it possibly should. There becomes an opportunity, especially with the repower situation, where you’re putting, instead of putting up a 1. 5, you’re putting up a 2.
3 or God forbid a 3. So what else is cooking Lars? What else you got going?
Lars Bendsen: We have a ton of stuff going with our new partners in the control. That’s a drone company. They hate when I say the drone company, because it’s a trains, planes and automobiles, because they can on helicopters or airplanes or drones.
But they could do more than just, taking pictures of blades. It’s the most boring thing in the world now. There’s more than 20 suppliers, so we try to get away from that market.
Joel Saxum: Yeah. Was it, I was talking with Yannick on your team, I think yesterday, and he said that they saw a 14 drone providers respond to an RFQ.
Lars Bendsen: It was FQ for the 17 companies. 1714. Were bidding on the same work.
Joel Saxum: I didn’t know there was that many drones. I didn’t know that many still around.
Lars Bendsen: And it’s just a beaten down market, so it’s not even interested. But those guys can we’re working now on doing ultrasonic testing on the blades. Sure, yeah.
So when we’re up on the blade, we see a lightning strike, we want to check, what is it? How deep is it going? Is it just a scratch? Or is it really doing some damage? We do the ultrasonic, then we can give a more accurate quote to the customer. Because now we know what it is. Instead of having to grind into it.
But right now it could be between 2, 500 and 60, 000. The last one. The same picture. One was literally 2, 500 and the next one was 6, 000 to 5, 000 for the same picture.
Joel Saxum: Yeah, because once you start opening it up, that’s a problem with all the blade repair campaigns. Oh, it’s the same. It’s hey, bid on these, and you’re like, I don’t know, it could be 10, 000 to 50, 000.
Lars Bendsen: Janick spent a month and a half, he couldn’t go to Calgary last year. He was sitting a month and a half and he took 400 and somewhat. Damages. Give me a price on that. Good job, Yannick. Thank you. He’s losing his hair from that, too. So it’s basically a qualified guessing competition. Yeah. There’s not really any merit to it.
Joel Saxum: And then when procurement steps in, it’s a qualified guessing competition for the lowest price.
Lars Bendsen: Yeah, then again, so we’re not bidding on the same terms. What if one of our competitors say, best case scenario? Sure. And we have a realistic, and we have a European square brain, so we do the worst case in the area.
Yeah. $50,000, 2,500 go. Those guys. Everything is done on t and m anyhow. So you to get an extra bill. Where we are more real, more realistic or trying to be more, you’re getting closer to what their budget is actually. Yeah. We trying to get more well leveled. Yeah, true. And again, it is a qualified guessing competition, but now new technology coming in.
But that also sonic scanning with a drone, flying a drone up on the blade, and also sonic scanning. That’s cool. That’s cool. They do x ray of transmission lines, all the splices.
Allen Hall: Oh sure, that’s where the failure points are.
Lars Bendsen: They have to be x rayed. So they’re flying an x ray with a drone.
Allen Hall: Oh, okay.
Lars Bendsen: And they’re starting a new project now, we have two drones.
Because when you get x rayed in the hospital, there’s a back plate. Yeah. So now they’re flying two drones, one upside down, and one here. And doing the lines. And scanning it. Are they going to bring that to the blade room? They have it already. No not the x ray part.
Joel Saxum: If you get x ray blades, I looked at a project like that about six years ago.
And we were like, ah, it’s difficult because those have to fly in unison. The base plate cannot move because then it gets blurry. But if you can figure that out for blades.
Lars Bendsen: I don’t know if they, on the blade side, but they’re doing a ton of stuff on the same transmission lines to doing a foundations.
Yeah, those are big areas. I’ve even developed a system that would blow my mind. So you’re flying with a drone in the tower, inside the tower, to check the foundation there. You open the hatches and it flies directly up and do internal inspection of the blades. You’re flying with a drone from the ground.
From the ground? From the ground. You’re flying inside the tower with a drone.
Joel Saxum: We’ll have to get those guys on the podcast. Yeah, I haven’t seen that. So that’s what I’m saying.
Lars Bendsen: As the A people based on bringing new technology in. Yeah. So that’s right down our DNA get totally excited when I see that.
Yeah. Because, and we have brought in, we talked about last time, 27 or 30 companies over from Europe to North America the last 10 years. Yeah. But that’s something that, that triggers me. But they’re not American. They’re Canadian, so everyone Right.
Yeah. That’s, so that’s what’s going on. And that’s why we need to be more clear now. communication because we have so many offerings. That’s an ISP with a different approach and then our optimization, I would call it, and new technologies.
Joel Saxum: And you guys doing spare parts and stuff too.
If you need something figured out, you’re call ours. Yeah. He’ll find you brake pads and gear oil and pitch alignment. I’m so happy.
Lars Bendsen: We have people in the office now helping out. So yeah, we increase our staff for 40%.
Joel Saxum: Shout out to Sydney, the new office manager, who keeps these guys in line.
Lars Bendsen: Absolutely. Absolutely. She is amazing. This would not be possible at all without her. She’s annoyingly organized.
Allen Hall: So Lars, how do people reach AC883? Because you’re such a wealth of knowledge and AC883 is starting to get really busy. So people gotta reach out.
Lars Bendsen: Gotta reach out. I was about to say our website, but that’s going to be renewed. It’s Lars, lars@ac883.com.
Allen Hall: There you go. Lars, thanks so much for being on the podcast.
And thanks for sharing a booth with us this week at ACP. And yeah, we’ll see you next time.
Hopefully in Hamburg.
Lars Bendsen: We will see in Hamburg, September latest. Absolutely. Thank you so much. Yes. Thank you

Wind Industry Operations: In Wind’s Next Chapter, Operations take center stage
Wind Industry Operations: In Wind’s Next Chapter, Operations take center stage
This exclusive article originally appeared in PES Wind 4 – 2025 with the title, Operations take center stage in wind’s next chapter. It was written by Allen Hall and other members of the WeatherGuard Lightning Tech team.
As aging fleets, shrinking margins, and new policies reshape the wind sector, wind energy operations are in the spotlight. The industry’s next chapter will be defined not by capacity growth, but by operational excellence, where integrated, predictive maintenance turns data into decisions and reliability into profit.
Wind farm operations are undergoing a fundamental transformation. After hosting hundreds of conversations on the Uptime Wind Energy Podcast, I’ve witnessed a clear pattern: the most successful operators are abandoning reactive maintenance in favor of integrated, predictive strategies. This shift isn’t just about adopting new technologies; it’s about fundamentally rethinking how we manage aging assets in an era of tightening margins and expanding responsibilities.
The evidence was overwhelming at this year’s SkySpecs Customer Forum, where representatives from over 75% of US installed wind capacity gathered to share experiences and strategies. The consensus was clear: those who integrate monitoring, inspection, and repair into a cohesive operational strategy are achieving dramatic improvements in reliability and profitability.
Takeaway: These options have been available to wind energy operations for years; now, adoption is critical.
Why traditional approaches to wind farm operations are failing
Today’s wind operators face an unprecedented convergence of challenges. Fleets installed during the 2010-2015 boom are aging in unexpected ways, revealing design vulnerabilities no one anticipated. Meanwhile, the support infrastructure is crumbling; spare parts have become scarce, OEM support is limited, and insurance companies are tightening coverage just when operators need them most.
The situation is particularly acute following recent policy changes. The One Big Beautiful Bill in the United States has fundamentally altered the economic landscape. PTC farming is no longer viable; turbines must run longer and more reliably than ever before. Engineering teams, already stretched thin, are being asked to manage not just wind assets but solar and battery storage as well. The old playbook simply doesn’t work anymore.
Consider the scope of just one challenge: polyester blade failures. During our podcast conversation with Edo Kuipers of We4Ce, we learned that an estimated 30,000 to 40,000 blades worldwide are experiencing root bushing issues. ‘After a while, blades are simply flying off,’ Kuipers explained. The financial impact of a single blade failure can exceed €300,000 when you factor in replacement costs, lost production, and crane mobilization. Yet innovative repair solutions, like the one developed by We4Ce and CNC Onsite, can address the same problem for €40,000 if caught early. This pattern repeats across every major component. Gearbox failures that once required complete replacement can now be predicted months in advance. Lightning damage that previously caused catastrophic failures can be prevented with inexpensive upgrades and real-time monitoring. All these solutions are based on the principle that predicted maintenance is better than an expensive surprise.
Seeing problems before they happeny, and potential risks
The transformation begins with visibility. Modern monitoring systems reveal problems that traditional methods miss entirely. Eric van Genuchten of Sensing360 shared an eye-opening statistic on our podcast: ‘In planetary gearbox failures, they get 90%, so there’s still 10% of failures they cannot detect.’ That missing 10% represents the catastrophic failures that destroy budgets and production targets. Advanced monitoring technologies are filling these gaps. Sensing360’s fiber optic sensors, for example, detect minute deformations in steel components, revealing load imbalances and fatigue progression invisible to traditional monitoring. ‘We integrate our sensors in steel and make rotating equipment smarter,’ van Genuchten explained.
Other companies are deploying acoustic systems to identify blade delamination, oil analysis for gearbox health, and electrical signature analysis for generator issues. Each technology adds a piece to the puzzle, but the real value comes from integration. The impact of load monitoring alone can be transformative.
As van Genuchten explained, ‘Twenty percent more loading on a gearbox or on a bearing is half of your life. The other way around, twenty percent less loading is double your life.’ With proper monitoring, operators can optimize load distribution across their fleet, extending component life while maximizing production.
But monitoring without action is just expensive data collection. The most successful operators are those who’ve learned to translate sensor data into operational decisions. This requires not just technology but organizational change, breaking down silos between monitoring, maintenance, and management teams.
In Wind Energy Operations, Early intervention makes the million-dollar difference
The economics of early intervention are compelling across every component type. The blade root bushing example from We4Ce illustrates this perfectly. With their solution, early detection means replacing just 24-30 bushings in about 24 hours of drilling work. Wait, and you’re looking at 60+ bushings and 60 hours of work. Early detection doesn’t just prevent catastrophic failure; it makes repairs faster, cheaper, and more reliable.
This principle extends throughout the turbine. Early-stage bearing damage can be addressed through targeted lubrication or minor adjustments. Incipient electrical issues can be resolved with cleaning or connection tightening. Small blade surface cracks can be repaired in a few hours before they propagate into structural damage requiring weeks of work.
Leading operators are implementing tiered response protocols based on monitoring data. Critical issues trigger immediate intervention. Developing problems are scheduled for the next maintenance window. Minor issues are monitored and addressed during routine service. This systematic approach reduces both emergency repairs and unnecessary maintenance, optimizing resource allocation across the fleet.
Turning information into action
While monitoring generates data, platforms like SkySpecs’ Horizon transform that data into operational intelligence. Josh Goryl, SkySpecs’ Chief Revenue Officer, explained their evolution at the recent Customer Forum: ‘I think where we can help our customers is getting all that data into one place.
The game-changer is integration across data types. The company is working to combine performance data with CMS data to provide valuable insights into turbine health. This approach has been informed by operators across the world, who’ve discovered that integrated platforms deliver insights that siloed data can’t.
The platform approach also addresses the reality of shrinking engineering teams managing expanding portfolios. As Goryl noted, many wind engineers are now responsible for solar and battery storage assets as well. One platform managing multiple technologies through a unified interface becomes essential for operational efficiency.
The Integration Imperative for Wind Farm Operations
The most successful operators aren’t just adopting individual technologies; they’re integrating monitoring, inspection, and repair into a seamless operational system. This integration operates at multiple levels.
At the technical level, data from various monitoring systems feeds into unified platforms that provide comprehensive asset visibility. These platforms don’t just display data; they analyze patterns, predict failures, and generate work orders.
At the organizational level, integration means breaking down barriers between departments. This cross-functional collaboration transforms O&M from a cost center into a value driver. Building your improvement roadmap For operators ready to enhance their O&M approach, the path forward involves several key steps:
Assessing the Current State of your Wind Energy Operations
Document your maintenance costs, failure rates, and downtime patterns. Identify which problems consume the most resources and which assets are most critical to your wind farm operations.
Start with targeted pilots Rather than attempting wholesale transformation, begin with focused initiatives targeting your biggest pain points. Whether it’s blade monitoring, gearbox sensors, or repair innovations, starting with your largest issue will help you see the biggest benefit.
• Invest in integration, not just technology: the most sophisticated monitoring system is worthless if its data isn’t acted upon. Ensure your organization has the processes and culture to transform data into decisions – this is the first step to profitability in your wind farm operations.
Build partnerships, not just contracts: look for technology providers and service companies willing to share knowledge, not just deliver services. The goal is building capability, not dependency.
• Measure and iterate: track the impact of each initiative on your key performance indicators. Use lessons learned to refine your approach and guide future investments.
The competitive advantage
The wind industry has reached an inflection point. With increasingly large and complex turbines, monitoring needs to adapt with it. The era of flying blind is over.
In an industry where margins continue to compress and competition intensifies, operational excellence has become a key differentiator. Those who master the integration of monitoring, inspection, and repair will thrive. Those who cling to reactive maintenance face escalating costs and declining competitiveness.
The technology exists. The business case is proven. The early adopters are already reaping the benefits. The question isn’t whether to transform your O&M approach, but how quickly you can adapt to this new reality.

Welcome to Uptime Spotlight, shining Light on Wind. Energy’s brightest innovators. This is the Progress Powering Tomorrow.
Allen Hall: Chris, welcome back to the show.
Chris Cieslak: It’s great to be back. Thank you very much for having me on again.
Allen Hall: It’s great to see you in person, and a lot has been happening at Blade Bugs since the last time I saw Blade Bug in person. Yeah, the robot. It looks a lot different and it has really new capabilities.
Chris Cieslak: So we’ve continued to develop our ultrasonic, non-destructive testing capabilities of the blade bug robot.
Um, but what we’ve now added to its capabilities is to do horizontal blade scans as well. So we’re able to do blades that are in lay down yards or blades that have come down for inspections as well as up tower. So we can do up tower, down tower inspections. We’re trying to capture. I guess the opportunity to inspect blades after transportation when they get delivered to site, to look [00:01:00] for any transport damage or anything that might have been missed in the factory inspections.
And then we can do subsequent installation inspections as well to make sure there’s no mishandling damage on those blades. So yeah, we’ve been just refining what we can do with the NDT side of things and improving its capabilities
Joel Saxum: was that need driven from like market response and people say, Hey, we need, we need.
We like the blade blood product. We like what you’re doing, but we need it here. Or do you guys just say like, Hey, this is the next, this is the next thing we can do. Why not?
Chris Cieslak: It was very much market response. We had a lot of inquiries this year from, um, OEMs, blade manufacturers across the board with issues within their blades that need to be inspected on the ground, up the tap, any which way they can.
There there was no, um, rhyme or reason, which was better, but the fact that he wanted to improve the ability of it horizontally has led the. Sort of modifications that you’ve seen and now we’re doing like down tower, right? Blade scans. Yeah. A really fast breed. So
Joel Saxum: I think the, the important thing there is too is that because of the way the robot is built [00:02:00] now, when you see NDT in a factory, it’s this robot rolls along this perfectly flat concrete floor and it does this and it does that.
But the way the robot is built, if a blade is sitting in a chair trailing edge up, or if it’s flap wise, any which way the robot can adapt to, right? And the idea is. We, we looked at it today and kind of the new cage and the new things you have around it with all the different encoders and for the heads and everything is you can collect data however is needed.
If it’s rasterized, if there’s a vector, if there’s a line, if we go down a bond line, if we need to scan a two foot wide path down the middle of the top of the spa cap, we can do all those different things and all kinds of orientations. That’s a fantastic capability.
Chris Cieslak: Yeah, absolutely. And it, that’s again for the market needs.
So we are able to scan maybe a meter wide in one sort of cord wise. Pass of that probe whilst walking in the span-wise direction. So we’re able to do that raster scan at various spacing. So if you’ve got a defect that you wanna find that maximum 20 mil, we’ll just have a 20 mil step [00:03:00] size between each scan.
If you’ve got a bigger tolerance, we can have 50 mil, a hundred mil it, it’s so tuneable and it removes any of the variability that you get from a human to human operator doing that scanning. And this is all about. Repeatable, consistent high quality data that you can then use to make real informed decisions about the state of those blades and act upon it.
So this is not about, um, an alternative to humans. It’s just a better, it’s just an evolution of how humans do it. We can just do it really quick and it’s probably, we, we say it’s like six times faster than a human, but actually we’re 10 times faster. We don’t need to do any of the mapping out of the blade, but it’s all encoded all that data.
We know where the robot is as we walk. That’s all captured. And then you end up with really. Consistent data. It doesn’t matter who’s operating a robot, the robot will have those settings preset and you just walk down the blade, get that data, and then our subject matter experts, they’re offline, you know, they are in their offices, warm, cozy offices, reviewing data from multiple sources of robots.
And it’s about, you know, improving that [00:04:00] efficiency of getting that report out to the customer and letting ’em know what’s wrong with their blades, actually,
Allen Hall: because that’s always been the drawback of, with NDT. Is that I think the engineers have always wanted to go do it. There’s been crush core transportation damage, which is sometimes hard to see.
You can maybe see a little bit of a wobble on the blade service, but you’re not sure what’s underneath. Bond line’s always an issue for engineering, but the cost to take a person, fly them out to look at a spot on a blade is really expensive, especially someone who is qualified. Yeah, so the, the difference now with play bug is you can have the technology to do the scan.
Much faster and do a lot of blades, which is what the de market demand is right now to do a lot of blades simultaneously and get the same level of data by the review, by the same expert just sitting somewhere else.
Chris Cieslak: Absolutely.
Joel Saxum: I think that the quality of data is a, it’s something to touch on here because when you send someone out to the field, it’s like if, if, if I go, if I go to the wall here and you go to the wall here and we both take a paintbrush, we paint a little bit [00:05:00] different, you’re probably gonna be better.
You’re gonna be able to reach higher spots than I can.
Allen Hall: This is true.
Joel Saxum: That’s true. It’s the same thing with like an NDT process. Now you’re taking the variability of the technician out of it as well. So the data quality collection at the source, that’s what played bug ducts.
Allen Hall: Yeah,
Joel Saxum: that’s the robotic processes.
That is making sure that if I scan this, whatever it may be, LM 48.7 and I do another one and another one and another one, I’m gonna get a consistent set of quality data and then it’s goes to analysis. We can make real decisions off.
Allen Hall: Well, I, I think in today’s world now, especially with transportation damage and warranties, that they’re trying to pick up a lot of things at two years in that they could have picked up free installation.
Yeah. Or lifting of the blades. That world is changing very rapidly. I think a lot of operators are getting smarter about this, but they haven’t thought about where do we go find the tool.
Speaker: Yeah.
Allen Hall: And, and I know Joel knows that, Hey, it, it’s Chris at Blade Bug. You need to call him and get to the technology.
But I think for a lot of [00:06:00] operators around the world, they haven’t thought about the cost They’re paying the warranty costs, they’re paying the insurance costs they’re paying because they don’t have the set of data. And it’s not tremendously expensive to go do. But now the capability is here. What is the market saying?
Is it, is it coming back to you now and saying, okay, let’s go. We gotta, we gotta mobilize. We need 10 of these blade bugs out here to go, go take a scan. Where, where, where are we at today?
Chris Cieslak: We’ve hads. Validation this year that this is needed. And it’s a case of we just need to be around for when they come back round for that because the, the issues that we’re looking for, you know, it solves the problem of these new big 80 a hundred meter plus blades that have issues, which shouldn’t.
Frankly exist like process manufacturer issues, but they are there. They need to be investigated. If you’re an asset only, you wanna know that. Do I have a blade that’s likely to fail compared to one which is, which is okay? And sort of focus on that and not essentially remove any uncertainty or worry that you have about your assets.
’cause you can see other [00:07:00] turbine blades falling. Um, so we are trying to solve that problem. But at the same time, end of warranty claims, if you’re gonna be taken over these blades and doing the maintenance yourself, you wanna know that what you are being given. It hasn’t gotten any nasties lurking inside that’s gonna bite you.
Joel Saxum: Yeah.
Chris Cieslak: Very expensively in a few years down the line. And so you wanna be able to, you know, tick a box, go, actually these are fine. Well actually these are problems. I, you need to give me some money so I can perform remedial work on these blades. And then you end of life, you know, how hard have they lived?
Can you do an assessment to go, actually you can sweat these assets for longer. So we, we kind of see ourselves being, you know, useful right now for the new blades, but actually throughout the value chain of a life of a blade. People need to start seeing that NDT ultrasonic being one of them. We are working on other forms of NDT as well, but there are ways of using it to just really remove a lot of uncertainty and potential risk for that.
You’re gonna end up paying through the, you know, through the, the roof wall because you’ve underestimated something or you’ve missed something, which you could have captured with a, with a quick inspection.
Joel Saxum: To [00:08:00] me, NDT has been floating around there, but it just hasn’t been as accessible or easy. The knowledge hasn’t been there about it, but the what it can do for an operator.
In de-risking their fleet is amazing. They just need to understand it and know it. But you guys with the robotic technology to me, are bringing NDT to the masses
Chris Cieslak: Yeah.
Joel Saxum: In a way that hasn’t been able to be done, done before
Chris Cieslak: that. And that that’s, we, we are trying to really just be able to roll it out at a way that you’re not limited to those limited experts in the composite NDT world.
So we wanna work with them, with the C-N-C-C-I-C NDTs of this world because they are the expertise in composite. So being able to interpret those, those scams. Is not a quick thing to become proficient at. So we are like, okay, let’s work with these people, but let’s give them the best quality data, consistent data that we possibly can and let’s remove those barriers of those limited people so we can roll it out to the masses.
Yeah, and we are that sort of next level of information where it isn’t just seen as like a nice to have, it’s like an essential to have, but just how [00:09:00] we see it now. It’s not NDT is no longer like, it’s the last thing that we would look at. It should be just part of the drones. It should inspection, be part of the internal crawlers regimes.
Yeah, it’s just part of it. ’cause there isn’t one type of inspection that ticks all the boxes. There isn’t silver bullet of NDT. And so it’s just making sure that you use the right system for the right inspection type. And so it’s complementary to drones, it’s complimentary to the internal drones, uh, crawlers.
It’s just the next level to give you certainty. Remove any, you know, if you see something indicated on a a on a photograph. That doesn’t tell you the true picture of what’s going on with the structure. So this is really about, okay, I’ve got an indication of something there. Let’s find out what that really is.
And then with that information you can go, right, I know a repair schedule is gonna take this long. The downtime of that turbine’s gonna be this long and you can plan it in. ’cause everyone’s already got limited budgets, which I think why NDT hasn’t taken off as it should have done because nobody’s got money for more inspections.
Right. Even though there is a money saving to be had long term, everyone is fighting [00:10:00] fires and you know, they’ve really got a limited inspection budget. Drone prices or drone inspections have come down. It’s sort, sort of rise to the bottom. But with that next value add to really add certainty to what you’re trying to inspect without, you know, you go to do a day repair and it ends up being three months or something like, well
Allen Hall: that’s the lightning,
Joel Saxum: right?
Allen Hall: Yeah. Lightning is the, the one case where every time you start to scarf. The exterior of the blade, you’re not sure how deep that’s going and how expensive it is. Yeah, and it always amazes me when we talk to a customer and they’re started like, well, you know, it’s gonna be a foot wide scarf, and now we’re into 10 meters and now we’re on the inside.
Yeah. And the outside. Why did you not do an NDT? It seems like money well spent Yeah. To do, especially if you have a, a quantity of them. And I think the quantity is a key now because in the US there’s 75,000 turbines worldwide, several hundred thousand turbines. The number of turbines is there. The number of problems is there.
It makes more financial sense today than ever because drone [00:11:00]information has come down on cost. And the internal rovers though expensive has also come down on cost. NDT has also come down where it’s now available to the masses. Yeah. But it has been such a mental barrier. That barrier has to go away. If we’re going going to keep blades in operation for 25, 30 years, I
Joel Saxum: mean, we’re seeing no
Allen Hall: way you can do it
Joel Saxum: otherwise.
We’re seeing serial defects. But the only way that you can inspect and or control them is with NDT now.
Allen Hall: Sure.
Joel Saxum: And if we would’ve been on this years ago, we wouldn’t have so many, what is our term? Blade liberations liberating
Chris Cieslak: blades.
Joel Saxum: Right, right.
Allen Hall: What about blade route? Can the robot get around the blade route and see for the bushings and the insert issues?
Chris Cieslak: Yeah, so the robot can, we can walk circumferentially around that blade route and we can look for issues which are affecting thousands of blades. Especially in North America. Yeah.
Allen Hall: Oh yeah.
Chris Cieslak: So that is an area that is. You know, we are lucky that we’ve got, um, a warehouse full of blade samples or route down to tip, and we were able to sort of calibrate, verify, prove everything in our facility to [00:12:00] then take out to the field because that is just, you know, NDT of bushings is great, whether it’s ultrasonic or whether we’re using like CMS, uh, type systems as well.
But we can really just say, okay, this is the area where the problem is. This needs to be resolved. And then, you know, we go to some of the companies that can resolve those issues with it. And this is really about played by being part of a group of technologies working together to give overall solutions
Allen Hall: because the robot’s not that big.
It could be taken up tower relatively easily, put on the root of the blade, told to walk around it. You gotta scan now, you know. It’s a lot easier than trying to put a technician on ropes out there for sure.
Chris Cieslak: Yeah.
Allen Hall: And the speed up it.
Joel Saxum: So let’s talk about execution then for a second. When that goes to the field from you, someone says, Chris needs some help, what does it look like?
How does it work?
Chris Cieslak: Once we get a call out, um, we’ll do a site assessment. We’ve got all our rams, everything in place. You know, we’ve been on turbines. We know the process of getting out there. We’re all GWO qualified and go to site and do their work. Um, for us, we can [00:13:00] turn up on site, unload the van, the robot is on a blade in less than an hour.
Ready to inspect? Yep. Typically half an hour. You know, if we’ve been on that same turbine a number of times, it’s somewhere just like clockwork. You know, muscle memory comes in, you’ve got all those processes down, um, and then it’s just scanning. Our robot operator just presses a button and we just watch it perform scans.
And as I said, you know, we are not necessarily the NDT experts. We obviously are very mindful of NDT and know what scans look like. But if there’s any issues, we have a styling, we dial in remote to our supplement expert, they can actually remotely take control, change the settings, parameters.
Allen Hall: Wow.
Chris Cieslak: And so they’re virtually present and that’s one of the beauties, you know, you don’t need to have people on site.
You can have our general, um, robot techs to do the work, but you still have that comfort of knowing that the data is being overlooked if need be by those experts.
Joel Saxum: The next level, um, commercial evolution would be being able to lease the kit to someone and or have ISPs do it for [00:14:00] you guys kinda globally, or what is the thought
Chris Cieslak: there?
Absolutely. So. Yeah, so we to, to really roll this out, we just wanna have people operate in the robots as if it’s like a drone. So drone inspection companies are a classic company that we see perfectly aligned with. You’ve got the sky specs of this world, you know, you’ve got drone operator, they do a scan, they can find something, put the robot up there and get that next level of information always straight away and feed that into their systems to give that insight into that customer.
Um, you know, be it an OEM who’s got a small service team, they can all be trained up. You’ve got general turbine technicians. They’ve all got G We working at height. That’s all you need to operate the bay by road, but you don’t need to have the RAA level qualified people, which are in short supply anyway.
Let them do the jobs that we are not gonna solve. They can do the big repairs we are taking away, you know, another problem for them, but giving them insights that make their job easier and more successful by removing any of those surprises when they’re gonna do that work.
Allen Hall: So what’s the plans for 2026 then?
Chris Cieslak: 2026 for us is to pick up where 2025 should have ended. [00:15:00] So we were, we were meant to be in the States. Yeah. On some projects that got postponed until 26. So it’s really, for us North America is, um, what we’re really, as you said, there’s seven, 5,000 turbines there, but there’s also a lot of, um, turbines with known issues that we can help determine which blades are affected.
And that involves blades on the ground, that involves blades, uh, that are flying. So. For us, we wanna get out to the states as soon as possible, so we’re working with some of the OEMs and, and essentially some of the asset owners.
Allen Hall: Chris, it’s so great to meet you in person and talk about the latest that’s happening.
Thank you. With Blade Bug, if people need to get ahold of you or Blade Bug, how do they do that?
Chris Cieslak: I, I would say LinkedIn is probably the best place to find myself and also Blade Bug and contact us, um, through that.
Allen Hall: Alright, great. Thanks Chris for joining us and we will see you at the next. So hopefully in America, come to America sometime.
We’d love to see you there.
Chris Cieslak: Thank you very [00:16:00] much.
