    Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow

    Allen Hall: Gio, welcome back to the program. 

    Gio Scialdone: Hey, thanks, Allen. 

    Allen Hall: So a lot’s happened over the past year since we last spoke with you at 3S Lift. Yeah. And there’s all kinds of new technology and improvements and the- The expansion of the Climb Auto system in the United States is remarkable. Yeah. How many systems do you have installed in North America?

    Gio Scialdone: Yeah, I appreciate that. I mean, it’s, it’s… The, the pride that we take in, in those numbers are, are serious. We, we feel, uh, a great responsibility to help technicians, to help our customers operate more, uh, more efficiently. We have 30,000 installed. 

    Allen Hall: Wow. 

    Gio Scialdone: So yeah, last year was a busy year. We installed close to 8,000, uh, in North America, so a bit in Canada as well.

    Um, [00:01:00] yeah, it’s… And, you know, before we get into some more numbers too, a funny story for you, a Massachusetts native- Right … or lived in Massachusetts- Long time … for a period of time. Uh, Hoosac Wind Farm, you know the Hoosac Wind Farm. Oh, yeah, yeah, 

    Allen Hall: I can see it out my front door. 

    Gio Scialdone: This is what’s great about this industry and being at this conference.

    Um, I ran into… At, at one point in time working for GE a long time ago, I was a site construction manager for Hoosac. I ran into my EHS safety manager, who I haven’t seen in 14 years- 

    Allen Hall: Wow … 

    Gio Scialdone: uh, who now works for another prominent, uh, company, uh, in the industry, and, uh, she remembered the name of my dog that- Really?

    I used to take to the site as a- Oh, 

    Allen Hall: wow. 

    Gio Scialdone: So, uh, you know, it’s good to be here, see you, and see, see, you know, lots of former colleagues, so, 

    Allen Hall: you know. Well, it’s a small world in wind. 

    Gio Scialdone: It’s a very small world. And, you know, we’re, we’re a company that, um, you know, again, we, we, we have a unique product, and there, there are some other companies that are, um, also coming out with a product quite similar, and we, [00:02:00] we appreciate that competition.

    Sure. In fact, I think, you know, we spend a lot of our time trying to, uh, sell our customers on the value that the ClimbAuto system is a need and not a nice to have, and I think having some competition with a similar ladder access product further, uh, maybe pushes that point to, to, to be true. So, um, you know, it’s good to be here and see some expansion in, in our little, uh, you know, ladder lift space.

    Allen Hall: Well, I think it shows the work that 3S has done to demonstrate the value of that system. I remember several years ago, I think when I first talked to you, there wasn’t a lot of adoption, and you were… And the operators were thinking, “Do I really need this?” But the reality was that the technicians loved it.

    They improved performance. They had technicians using those towers and wanted to work on those specific towers. Yeah. And, and then, uh, just kind of the flood happened. It, it was everybody was testing the [00:03:00] waters. You were basically installing test systems- Yeah … or sort of sample system to try it. Yeah.

    Everybody loved it, and then boom, you’re up to 30,000 units. 

    Gio Scialdone: I, I think, I think a part of that too to add on is you, you have to have a quality product. 

    Allen Hall: Oh, sure. It has to work. For, for… It has to work. Right. 

    Gio Scialdone: That’s the most important thing. Yeah. Um- The th- the, the, the value and the function in theory makes sense to lots of people, but does it work and is it reliable?

    And I think having been here nine years and, and, you know, the first three years we only had 500 units installed. Yeah. So it’s really the last three or four years that have expanded our, our installation base. And I think a lot of that is, you know, thank, you know, we’ve got a great team behind it. You know, we’ve got 70 technicians, and we’ve got a sales team, and an engineering team, and, um, you know, a project management team.

    So we, we’ve, we’ve staffed up as, as you need to. But the product we’ve, we, we really believe has, um, you know, been our best [00:04:00] salesperson. You know, it takes some service. That’s one thing I wanted to, to let you know, too. You know, in the early days, we- a lot of our customers were servicing our lifts. Sure.

    Right, yeah. And we still, um, uh, promote that if they would like to. Uh, annual inspection, you know, 30 minutes a year, um, that kind of pre-use inspection of one or two minutes before you ride it is- Sure … is, is, uh- Yeah, yeah … required. But now we’ve got a team of 20 to 25 technicians who their only job is to go around and, and service these lifts.

    So- Wow … we’re proud now that, you know, the oldest lifts are nine years. Oh, wow. And they’re still working very, very well as designed. You know, no, no major correctives, no motor replacements. So, you know, stand behind the product and, and, you know, service it, and servicing our customers is really what we’re, we’re proud to, to, to show.

    Allen Hall: Well, that was always the hard part early on. Um, my recollection was I could install this system, and yes, I could help my technicians, but am I fixing it, replacing it? The, the, the quality was the question mark at the moment. 

    Gio Scialdone: Yeah. 

    Allen Hall: [00:05:00] But you’ve really hammered that, and I think 3S has done a good job of mainta- maintenance and inspections and just delivering a quality product.

    That’s why I think you’ve seen the growth as rapidly as you have, and the price point’s right, too. 

    Gio Scialdone: The price point has to be right. I think, you know, um, we’ve– we, we are offering some additional, let’s call them, like, support services. So we’ve got an online store where you can come and buy spare parts. You can buy every spare part that you need on our online store.

    Allen Hall: Nice. 

    Gio Scialdone: You know, accessories are required, fall arresters and battery kits and things like that, that even if you’re an ISP or, or a third party, uh, not the owner per se, you, you need that, that, that equipment. In addition to the online store, we- we, last year we launched, uh, an online training academy. So what’s…

    You know, it’s a very simple system to use. We’ve seen it. I’ve seen it. Used it. 

    Allen Hall: Yeah. 

    Gio Scialdone: Um, but we need to make sure as an industry and as a company that we take responsibility to make sure as, as best we can that every [00:06:00]person that uses this uses it appropriately and has the intelligence and the knowledge and skills to, um, troubleshoot basic things or perform safety evacuation features.

    So we’ve got an online training, um, uh, academy that we launched last year, and that’s been going well too. So more information we feel is better, uh, for our customers, for our technicians. Sure. You know. Um, so that’s been fantastic to see a lot more activity and customer… Again, a really small, you know, $200 per, per training course, and the certificate’s good for two years.

    You know, um, a robust course for an hour or two. It’s worth it. 

    Allen Hall: Well, it’s a reasonable price for an excellent product. Yeah. And that’s been the key for a long time. Yeah. Opening up the ability to get spare parts online, that’s huge. I know when you talk to operators, what’s the pain point? I have to call somebody- Yeah

    somewhere far away to try to get a part. Sure. It’s gonna take six months to get it. 

    Gio Scialdone: Yeah. 

    Allen Hall: Getting it online is the way- Yeah … that they wanna do it. [00:07:00] So it’s a lot of smart moves to be the support part of, of that system. 

    Gio Scialdone: Yeah. We’ve come… I’m, I’m smiling because in Chicago, uh, maybe seven years ago, our, our first spill- spare parts process was-

    uh, my office had a closet that I housed all the spare parts. 

    Allen Hall: Yeah. 

    Gio Scialdone: You know? And, and when I needed to ship out something, I put it in a box and gave it to the, to, like, the building secretary, you know? That’s how it worked. And now we’re, we’re a little more sophisticated than that. We’ve- Y- you got a 

    Allen Hall: massive organization 

    Gio Scialdone: behind it We’ve got a 40,000 square foot warehouse that we’re, we’re really proud of, and a great team behind it to perform the logistics and track everything and…

    You know. So yeah, we’ve, we’ve come a long way, and our customers are helping us try to get better as well, you know. There’s still, there’s still a long way to go. Our objective as a company is to eliminate climbing, Alan. And it- And, and, and you know, I think there’s not much pushback, frankly. 

    Allen Hall: Not today.

    Right? Three years ago, a lot of pushback. 

    Gio Scialdone: Yeah. Yeah. I think, um… And what I mean, too, is, like, I think- From a, uh, a [00:08:00] value perspective, there’s no pushback. There’s still a budget perspective. Sure. And I think the challenges we’re finding still are if you’re at a wind farm and you have blade issues or, or, or drive train issues, uh, you might need to spend your dollars there before you spend them on a lift, and we, we, we understand and respect that.

    And so we’re working together with customers to try to come up with creative commercial solutions, be it, uh, you know, deferred payment models or multi-year, look at that as a, a capital cost plus some operational cost. Smart. Defer some of that capital, um, to, to sort of reduce that first year burden, right?

    Allen Hall: Yeah. So- That’s the 

    Gio Scialdone: scary 

    Allen Hall: part, right? They, they… The lump sum- It’s a big budget item. Yeah … is always an item, and they, especially in today’s world where we got gearbox and blade issues, they don’t want to spend on something that’s not directly there because it’s the, that’s what- Yeah … produces power. 

    Gio Scialdone: Right.

    Allen Hall: But technicians working on the turbines also produce power. That’s a great point. 

    Gio Scialdone: And 

    Allen Hall: you, and you need them, they go up and down- Yeah. That’s a good point … and sometimes you need them to go up and down a lot. Yeah. And if you don’t [00:09:00] wanna wear out those technicians, the, the lift is the way, the climb model system is the way to go.

    Right. It just makes… In today’s world, not having it, you’re the odd one out because most sites have some, if not all the turbines with the climb model system. 

    Gio Scialdone: There’s a, a… It reminded me of a, I talked to a customer today who said, you know, lots of these sites are clustered with phases. Uh, this particular customer retrofitted, uh, one of the two phases at their site.

    They’re split, let’s call it 50 turbines each or so, um, maybe two years ago, and then their struggle is they haven’t yet got the budget to do the second phase. Now, it’s the same group of 

    Allen Hall: technicians- 

    Gio Scialdone: Yeah … that work on both phases. So she, she explained to me that every morning when they go in and they kinda see which, which turbine they’re going to, there’s a, there’s a few of them going, “Yeah.”

    And there’s a couple other ones that are like, “Ah,” you know? Yeah. So there’s a real like… And I th- and I believe, you know, while that’s kind of a, an anecdotal kind of funny story, there’s, there’s, there’s real objective measures that you [00:10:00] can look at to say that it is, it is- correlated, hard to prove causation, but likely that those technicians who are climbing are gonna be less efficient at the same task than those who are not climbing, right?

    Yeah. And, and the customer knows that. And so, um, you know, we’ve gotten to that point as an industry that we’re, again, we’re not arguing the, the value too much anymore. That’s good. It’s more about finding the solution for the right, at the right time. Pre-repower, do we do it pro- post-repower? You know, those questions are being asked.

    Um, you know, it makes more sense potentially, if you will repower in a year, to put that in that budget. Um, so we’re seeing lots of that activity, especially as the lead up to this July 4th, uh, sa- uh, start a construction repower- Right … cliff. 

    Allen Hall: Yeah. Are, are you getting a lot of inquiries about that? Like, we wanna book a contract, try to get before that July date?

    Gio Scialdone: Yeah, look, one of the interesting things is, you know, to qualify for the PTC by [00:11:00] July 4th, you need to start construction. 

    Allen Hall: That’s right. 

    Gio Scialdone: Um, or, and you can do that in a couple different ways, right? Right. And we are having customers who are using our lifts as a start of physical work on site. 

    Allen Hall: Oh, 

    Gio Scialdone: that’s so smart.

    So they’re installing lifts- To start that process and show a continuous effort on site. It’s on-site work. Yes, it is. Uh, we have, you know, pri- uh, PWA, prevailing wage apprentice- Right … qualified- Sure … technicians in our program, if that’s something that’s required- Yeah … which a lot of times it is- It is

    nowadays on these, a lot of these sites. So, um, yeah, we’re offering both of those things to customers. It is an interpretation. There are some customers who aren’t, um, but, but there are, there are those that, that do see the lift as a great tool for them to start that, that clock. 

    Allen Hall: Right. So- Because the parts are there, you’re ready to go.

    You can get them- Yeah … installed and- Yeah … unlike other components of a wind turbine- That might 

    Gio Scialdone: have longer lead time … 

    Allen Hall: that will have longer lead times. Right. If you’re doing main bearings or something of that sort- Right … it’s gonna be several months before you get those assets on site and can [00:12:00] start working them.

    Gio Scialdone: Yeah. And you’ve got three months until July 4th, 

    Allen Hall: right? Right. You gotta go. 

    Gio Scialdone: Yeah, you gotta go. 

    Allen Hall: Right. And that- You gotta go … I think that’s, that’s the key to all this. Yeah. Boy, that, that’s genius. I’m, I’m glad that people- … are thinking outside the box. 

    Gio Scialdone: We are too. Our customers are creative. 

    Allen Hall: Yeah. 

    Gio Scialdone: And that’s good.

    We’re happy to support that, at times. 

    Allen Hall: So there’s, there’s some new technology at 3S in- involving evacuation and- Yeah … you know, the, one of the most, uh, critical pieces of being a technician is working safe, but occasionally things happen. Mm-hmm. And there’s a lot of ways to get technicians from the nacelle downtower.

    Some of them involve tossing them over side and roping them down, which can be kind of extreme, honestly. Mm-hmm. And a, a lot of technicians do get hurt in not necessarily life-threatening ways- Right … but in ways where it makes it really hard to kind of get them up and down- Safely, yeah … the, the tower safely, right.

    So 3S has been thinking about this for a while, and now you have a, a new product. 

    Gio Scialdone: We do. We have a rescue stretcher, uh, which has been in development for about a year or [00:13:00] so. We’ve tested it in the field. Um, yeah, the, the climb onto system with all its functions, uh, has not been a rescue system. Right. Right?

    Um, so what, what we’ve been doing is if, if there is an incident in the tower, you’re utilizing a, a, a, one of the many rescue devices that are in the industry. Sure. Now, w- with the stretcher, uh, this is a, a device that attaches to the ClimbAuto System and uses the ClimbAuto System to safely bring the person down.

    Um, it can be installed by, with one, uh, rescuer. So one person can fix this to the rail. It has pulley, uh, systems to bring the person up onto and attached to the ClimbAuto System, and then send down. Now, so then you’re, you’re, you’re immobilized, right? So we secure your head, your feet, your body. Um, and to your point earlier, yes, it’s in, in the event that an injury occurs [00:14:00] and you have, let’s call it some time, 10 to 15 minutes of setup time, ’cause that’s what it will take- Sure

    then this is a great product. And the idea would be, you know, one per truck, similar to a rescue device. Um, you know, and then, you know, you can, can get it up and down the tower pretty easily. It’s, it’s light. It, the package is like a, it’s like a tent bag. It folds up into, like, a bag of a tent, if you picture that.

    Um, it maybe weighs, like, 15 pounds. It’s quite light. Oh, that’s good. Yep, yep. You know, ’cause there’s no long rope, right? So there’s no, like, hundred-meter rope that you need, which is the, the heavy stuff. Right. Um, and, you know, so you’re using the lift. So the, the weight of the, the system, the stretcher itself, is quite light.

    So we’re excited. We’ve got a few customers that have demoed it. And, uh, yeah, we’re, we’re, we’re looking to continue to improve the, the, the, the features that we offer. Well, 

    Allen Hall: yeah. If, if there’s 30,000 ClimbAuto Systems out there- Mm … there should be these rescue kits along in the trucks- Yeah … because you just don’t know.

    Gio Scialdone: Yeah. 

    Allen Hall: Right? And guys get hurt. 

    Gio Scialdone: Yeah. 

    Allen Hall: They [00:15:00] dislocate their shoulders. They’re dislocating their knees. Yeah. It, it’s a hard task. It is. Uh, you used to climb and do that job. It is. You know that- It is … there’s, there’s things that happen uptower that it makes it hard to get down. 

    Gio Scialdone: You know, I remember doing some training w- where a lot, I mean, we all have, at some point, maybe done some rescue training and, you know, if you’re in a traditional uh, auto descent or sort of rescue device, you may be banging against the tower wall or the ladder- Yep

    potentially causing further injury. The benefit of this system is, is that, you know, you’re stable on the lift as you go down. Um, so yeah, it’s a little, um… We, we feel is gonna be helpful f- for the sites that have, for sure, climb auto systems, and again- … it’ll take some training. 

    Allen Hall: Sure. 

    Gio Scialdone: Right? Sure. It’ll take some training to, to…

    Just like any, any rescue device will take. Um, but we, we see some value in the future that, again, it’s adding… It’s another tool, uh, for customers- Yeah … to consider to keep their people safer. 

    Allen Hall: Yeah. 

    Gio Scialdone: You know? So. 

    Allen Hall: I, I, I- Yeah. I see a lot more operators now being very proactive about safety. 

    Gio Scialdone: Yeah. 

    Allen Hall: And if I can have a simple tool- Yeah

    that [00:16:00] makes life easier just in case, ’cause things happen, and you wanna be ready for it, something in, in the back of the truck makes infinite sense and is a, a smart way to handle it. Because the thing about tower heights today, we’re above 100 meters on a lot of towers. 

    Gio Scialdone: Yeah. 

    Allen Hall: And that’s a long way to get lifted down.

    Speaker: That’s 

    Gio Scialdone: true. Yeah. That’s a, it’s a… And, and, you know, and if you’re in a condition, a wind condition where it- 

    Allen Hall: Which is where these 

    Gio Scialdone: turbines 

    Allen Hall: are, 

    Gio Scialdone: yeah … towers sway, yeah. Then, then it’s- It’s- … even harder and need multiple people. You know, so again, in these remote areas where more and more turbines are being located as new construction, m- way more remote, uh, y- your, your, the next team of two technicians may be a, an hour away.

    Probably, yes. Right? Worst case, it could be an hour away. Yeah. Oh, 

    Allen Hall: yeah. 

    Gio Scialdone: And so as a team of two, you know, to be able to rescue you and safely bring you down, it could be critical. It could be critical. It 

    Allen Hall: will be. 

    Gio Scialdone: Yeah. Yeah, because there’s not gonna be a third or fourth person to come assist us 

    Allen Hall: for an hour, 

    Gio Scialdone: you know?

    So yeah, it’s an exciting… You know, [00:17:00] we, we’re, we’re trying to do, you know, uh, add-ons to the product to, uh, you know… We, we’ve modified some things over the years. We’ve got a new battery kit style, uh, to improve functionality. Clip-on battery as opposed to a plug-in. Um, you know, we’ve added a lot of different safety features over the years, like, um, uh, simultaneous handle switches.

    Right, yeah. So, you know, we’re, we’re trying to avoid, uh, a misuse of, of, uh, one hand at a time or no hands. Um, so there’s, there’s lots of features that we have, uh, added and also are able to, when we go service these t- towers- Bring the add-on at no cost if we’re performing the service for the customer. So we’re gonna upgrade your software, so to speak- Sure

    to the newest and latest, greatest software, um, so that, you know, you can be safer than, than you were maybe a few years ago. 

    Allen Hall: Oh, yeah. But that’s why you buy a 3S Climboto system. Ouch. Is because you know that those upgrades are coming. Yeah. And they’re- Yeah. You guys are not sitting still. You don’t have- No

    you hadn’t device- No … [00:18:00] created a device 10 years ago and haven’t changed it. Yeah. It’s evolved every single year- It has … that I’ve talked to you. Yeah. And every single year it’s safer, more reliable- Yeah … does more features, and the technicians love it. 

    Gio Scialdone: Yeah. 

    Allen Hall: Absolutely love it. 

    Gio Scialdone: I credit our, you know, our company is, is…

    This is our, this is our, uh, our passion, right? So, like, we’ve, we’ve been in this business for, for 20-plus years. In the US, we’ve been in it for nine and, you know, we’re not, we’re, we’re not going anywhere. No. You know, notwithstanding, um, uh, any, any, any political issues, we’re gonna ride through, so, so is everybody here, you know?

    Sure. Yeah. We’re, we’re, we’re in this and, you know, our mindset is, again, to eliminate climbing and, and do the best we can to keep people safer and have turbines run more efficiently. 

    Allen Hall: So if you’re an operator or a wind farm asset manager or site supervisor- Yeah … at a, at a wind farm and you don’t have the Climboto system yet Who do you call?

    Where do you go to get started? 

    Gio Scialdone: Yeah, you can, you can definitely get us on the [00:19:00]website. You know, there’s a Get Info button that still goes directly to me if you’re gonna say, “Hey, can I get a quote on this?” So, you know, we’ve got five salespeople. Uh, you can certainly ask your management team because there’s a l- strong likelihood that we’ve been in touch with them.

    We, we visit sites. You know, we visited 200 sites last year. So our… We’re out. We, we… You know, if, uh, if we haven’t visited you, let us know. But, um, you know, yeah, you can definitely reach us on, on the web or, uh, you know, we’ve got a phone number as well on there, so. 

    Allen Hall: Yeah, it’s easy to reach out. Yeah. Just look up 3S Lift.

    Climb Model System’s another quick way, and if you Google that you’ll get to the 3S Lift website, and you can find all the cool features, and, and the new devices, and you can find your parts and everything you want right there. It’s, it’s amazing the growth and, and the, and the, uh, adoption of that system.

    It’s, it’s great to hear. It’s one of those things that when it’s a real success story. Yeah. And I, I know you’re, you’re really close to it of course. 

    Gio Scialdone: Yeah, I know. 

    Allen Hall: Yeah. But from the outside looking in, it’s [00:20:00] amazing. 

    Gio Scialdone: We’re proud of 

    Allen Hall: the team. 500 turbines to 3,000, that’s a lot. 

    Gio Scialdone: It is. We’re proud of the team. I’m, I’m grateful to the customer base that, that have seen this, this value, you know, and recognize it.

    Um, and you know, not only for the soft sell, that it helps people and the morale, and, you know, there is a, a, a, a harder to measure injury improvement factor. 

    Allen Hall: Yeah. 

    Gio Scialdone: Um, but, but there’s absolutely some objective measures. We have sites that before the lifts were installed were at 95% availability, and now they’re at 96.2.

    Now, correlation and causation aren’t the same thing, but we, we believe, and we means the industry I think at this point, especially to see competitors come in, I think that further, uh, drives home the idea that this is the right thing to do, to stop climbing and, and help your t- technicians be more efficient, effective.

    So yeah, we’re, we’re proud of it and, um, you know, we’re looking forward to being here for another nine years. 

    Allen Hall: Absolutely. Yeah. Gio, so good to see you. Congratulations on everything. Thanks, Allen. And yeah, [00:21:00] good luck this year. I know you’re gonna have a l- a lot more growth, so- Thanks … congratulations.

    Gio Scialdone: Appreciate the time.

    Matthew Stead: [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: Welcome to this edition of the Uptime Wind Energy podcast. I’m Allen Hall here with Matthew Stead, Rosemary Barnes, and Yolanda Padron. And our week starts off in the courtroom. And if you’ve been watching the news lately, there’s a pretty substantial IRS case involving large-scale wind and solar having to do with the, uh, production tax credit and, uh, investment tax credit at the same time on the safe harbor, 5% safe harbor rule.

    Uh, a federal judge handed the wind industry and solar industry a pretty substantial legal win that could reshape how the [00:01:00] projects qualify for tax credits. So a judge up in, uh, the District of Columbia vacated IRS Notice 2025-42. So if you remember that, uh, from a- about a year or so ago, uh, f- it found that the, that notice was arbitrary and capricious under the Administrative Procedure Act.

    The notice, which was issued following a July 2025 executive order, had eliminated the 5% safe harbor for wind projects, uh, a provision developers have relied on since about 2013 to establish construction start dates without breaking ground. The court found the IRS failed to justify removing it, ignored industry comments, which I had read, and I agree with that, and gave no reason for treating wind differently f- than other clean energy technologies.

    So That his executive order came down and said, “Hey, we don’t like wind. [00:02:00] IRS, write a rule and make it hard for wind to get installed in the United States.” And so they dutifully did it, but a court is throwing it out. This has some pretty significant implications because if you hadn’t broken ground before this ruling, I think the– what was happening was be- if you hadn’t broken ground by July 4th, your project wouldn’t qualify for some tax credits.

    But now, if you have 5% safe harbor, you still are in the game, at least for now. Now, Wanda, that’s gonna make a big difference to asset managers and developers, won’t it? 

    Yolanda Padron: Yeah, it’s really exciting. I think it opens up the, the playing field for, for some of these projects that might be a little bit behind schedule.

    Um, of course, a lot of teams had to change their plans and their pipeline when, um, you know, the big, beautiful bill passed and, I mean, it’s– of course, it adds a little bit of additional volatility, right, to, to wind and, and solar in the US, but it’s exciting to see at least things for, [00:03:00] for those of us that are in the wind and solar side, the, it’s a little, little bit of, of hope there.

    Allen Hall: And Matthew, uh, even in terms of opening up o-o-operations and, uh, getting contracts signed, this should make a big difference in sort of opening the floodgates a little bit. Although there is a short timeframe. We’re, we’re recording on, what, what is today? June 10th. So you have, in theory, less than 30 days before the July 4th deadline, but hopefully this stays.

    You think there’s a chance this just gets completely, uh, wiped out, the executive order and the IRS notice and- It’s back to what we remember for the, for the last, ooh, 12, 13 years? 

    Matthew Stead: Uh, yeah. I’m, I’m, I’m hopeful, and I, I agree with Yolanda. I think you, you said it really well. Um, I think this is a, a glimmer of hope in, um, a sometimes gloomy, um, environment.

    So I think that’s great. In terms of going back to where it was, um, I mean, I guess my observation has been that, [00:04:00] you know, things in the US were a bit, um, distorted. You know, distorted through the, the PTC, um, and the whole repowering thing after 10 years is quite a distortion. So I think, um, you’re not necessarily going back to the good old days, um, might be the way, what will happen.

    Allen Hall: I think there is a lot of people actively trying to dig holes at the moment, and I, I’m sure they’re gonna continue to do that. Yolanda, do you th- you think anybody’s gonna stop and kinda say, “Oh, we have the 5% rule. We’re, we’re good”? Do you think, or you think they’re gonna still go ahead and really start construction and then just keep things continually moving on site?

    Yolanda Padron: I don’t think they, they can really stop, right? Because you, you don’t know if, if anything strange happens. A lot of people didn’t think the, a lot of the provisions in the big beautiful bill were gonna, were gonna see the light of day, and they did. Um, but it does, I really hope it brings at least a little bit of breathing room for some people.

    I know it’s, it must be… I mean, I have some friends in development, and they’re, they’re q- a little [00:05:00] bit stressed right now just with everything going on. Um, so, so I really hope for them at least they, you know, if, if they’re a little bit behind schedule, then it, it’ll be, it’ll still be fine. 

    Allen Hall: Delamination and bondline failures in blades are difficult problems to detect early.

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

    CIC-NDT maps every critical defect, delivers actionable reports, and provides support to get your blades back in service. So visit cicndt.com because catching blade problems early will save you millions[00:06:00]

    Norway’s Storting has voted to pause the 35 billion Norwegian krone support program for floating offshore wind at Utsira Nord. The Conservative Party secured a parliamentary majority for the external quality assurance review, a socioeconomic analysis, and a technology development assessment, all before the Storting will authorize any commitments.

    Equinor and Vårgrønn, along with EDF and Deepwind Offshore, each hold allocated 500-megawatt areas and were preparing to compete for that subsidy. Equinor says the project will continue for now. I think everybody is saying that at the moment. But, uh, Equinor cannot rule out consequences as framework uncertainty compounds in the already challenging nature of floating offshore wind development.

    So Utsira Nord is a massive project. So it’s, it’s about three and a half billion US dollars [00:07:00] to go do this. We had Mads Furuseth and Anders Naslund about a year or so ago, maybe a little bit longer, talking about the project and how big it was and how important it was that Norway did this for floating offshore wind.

    But with this, uh, recent change in the parliament of Norway, it does seem like they’re slowly going to try to kill it by putting in a number of, uh, reviews, which is how bureaucracies tend to kill things. Is put it under six, seven, eight reviews, different committees. They all take time to get together.

    They have to put out a report. It could be two, three years from now. At that point, the world has completely changed, and everybody’s moved on. Does that seem like the outcome here at the moment? 

    Matthew Stead: Yes. 

    Allen Hall: In my mind, there’s really two big areas for floating offshore, which UK, right? That there, there’s some massive projects there, Green Volt being one of them, and then there was Sue & Nord.

    So between the two, I feel like the, the UK one was going to [00:08:00] happen. The question whether the world was gonna move towards floating offshore wind was gonna happen up in Norway. If Norway decided to do it and could get it developed, and it has the capability to do it because, because they have that skill set, uh, right there in Norway.

    If they could do it in Norway, everybody in the world would learn from it and figure out how to do it. Does this really set back floating offshore wind globally? 

    Matthew Stead: Yeah. I mean, going back to what I said before, and I, I’ll defer to Rosie on this as well, but, um, when I was at, at Blades Europe, um, one of the, one of my long-term contacts, um, y- was in floating wind, um, and had, um, left the industry.

    He basically said i- in his view that the offshore wind industry was slowly, um, in decline or slowly dying. Um, so I’m just wondering if this is just evolution of viability of offshore wind. 

    Rosemary Barnes: Is offshore wind in decline? I think if you look globally, it’s, it’s not in decline. I, I haven’t looked in, in depth at the figures just based on what, you know, [00:09:00] headlines I’ve seen and podcasts I’ve heard, but I think that globally it’s still on the rise.

    It’s just that- It’s only in Europe that things are really moving with speed, right? Like, people were expecting heaps of growth in the US and now no- nobody expects that. Floating offshore wind, it’s… I th- I still think it’s too early to say. There are plenty of countries that don’t have any good energy options besides, um, floating offshore wind, like Japan.

    What their energy transition looks like is gonna depend a lot on their culture and what people think, ’cause, like, if you go through, like, the engineering solutions that Japan could have, the ones that make the most sense from an engineering point of view are not popular at all, are not politically viable.

    Like, Japan could easily have a subsea cable connecting it with, um, with China, for example, or Korea, but I don’t think anybody, anybody thinks that that will ever happen because, you know, politically it’s, it’s very far from being possible. What else could they have? Geothermal. They’ve got heaps of [00:10:00]geothermal resources, like really good traditional geothermal resources, but my understanding is that it’s super unpopular because their onsen, um, community doesn’t want it.

    Uh, my understanding is that they’re worried that if you put geothermal, um, if you exploit geothermal resources, then the onsens will not be hot anymore, and again, my limited research understanding is that it’s not true. It’s different resources. The two aren’t connected in any way. Um, and yeah, there’s actually a community geothermal, um, facility near Fukushima.

    I’m trying really hard to get over there, but I’m, I’ve got a roadblock at the moment because, uh, n- no one there speaks English, so I need to find somebody to, to come with me and, you know, I’ll have one, one day to try and get there on the fast train and back to Tokyo in, in a single day. So it’s, it’s a bit of a stretch, but I’m gonna try.

    But anyway, so yeah, what have we… We’ve ruled out, like, subsea cables, ruled out geothermal. Floating wind is good. 

    Allen Hall: Well, speaking of Fukushima, [00:11:00] there’s been a more recent push in Japan to start up some of the nuclear facilities. So after the tsunami, was that 2012, 2014 when that happened? It was a while ago.

    Uh, when the tsunami happened and h- had that, uh, nuclear accident, they, they s- shut down all the nuclear facilities in Japan, but it does seem like they’re trying to restart some of them And, and maybe it’s just the demand for energy and, and they’re trying to weigh that off with offshore wind or floating offshore wind.

    At what point, you know, which one do you choose? It has to be driven by cost and availability. 

    Rosemary Barnes: Yeah. And so Fukushima, I just looked it up, it was 2011. Um, and yeah, so I mean, I think it is very fair that they had a reaction to that and they wanted to put the handbrake on nuclear at that time, or they did more than put the handbrake on, they did like a handbrake turn.

    Allen Hall: They shut it down. 

    Rosemary Barnes: So, and it, you know, it’s gradually ramping up. I think that their target for nuclear now is to, to regain, um, 20% of their electricity from [00:12:00] nuclear by 2040, something like that. It was 30% prior to that incident. Um, so that will be part of it, but it’s not, um, it’s not all of it. And then even if you think of, uh, okay, so forget climate change, just, you know, we want, Japan just wants energy and they don’t care about climate change, you know, ’cause that, that, that could be true.

    What are their ch- choices for that? They import a whole bunch of… They, they import nearly all their energy. Everything that’s not nuclear basically is, is imported. Um, coal, but a lot of LNG, and, you know, that is not exactly an appealing prospect at the moment either. It’s not secure. Prices are very volatile.

    We’ve had, like, two fossil fuel shocks in the last, what, like four years or something like that, and how many more, how many more are we g- are we going to have? You know, like energy security is important, totally separate from climate change issues. So I don’t think we need to rely on Japan, like, you know, [00:13:00] steadfastly staying the course because their, their existing o- opportunities are not, are not great for fossil fuels either.

    Allen Hall: I don’t know what country’s gonna stay the course right now, really. Maybe the UK? 

    Rosemary Barnes: Oh, I think it’s- Countries that have other reasons for going to renewables are the ones that are gonna stay the, stay the course. Um, and there are plenty of examples of countries where it just, it is by far the easiest, cheapest, fastest option to get more electricity.

    Um, you know, like all of Africa, for example, is, is facing that as a, uh, a better development path than trying to build big, um, fossil fuel power plants. But even that, you know, like in India, they’re making a huge transition, Pakistan, not to mention Australia, where now batteries are having more of an impact on electricity prices than gas is.

    So our electricity prices now finally are dropping, um, this year for the first time because of how many batteries have come on and are now, you [00:14:00]know… Like they’ve just flattened. The evening price peak used to be on average about, like, I think $400 or something dollars a megawatt hour, and now it’s like 100.

    In one year we had that, we had that change, yeah, just from the amount of batteries that have come on in the last year or two. 

    Allen Hall: Why does that make such a big difference in the price of electricity, the battery aspect? 

    Rosemary Barnes: Because, so the way that Australia… Australia’s electricity market is pretty similar to Texas, so if you understand that, then you can probably understand Australia’s.

    But, you know, at any five-minute interval, people, like, they know how much demand there’s going to be, and then people are bidding in how much they would supply electricity for in that five minutes, in real time as well. It’s not like day ahead or anything like that in Australia. The, like, last one they need is what everybody gets paid.

    So, like, solar power is gonna bid in at, like, you know, practically zero, um, or maybe negative prices actually if they’ve got power purchase agreements in place. And then, you know, wind a little bit more, and then coal, uh, you know, a, a bit [00:15:00] more than that, and then gas, the open cycle gas turbines, the peakers, they’re very expensive.

    They’re bidding in at 400, $400 a megawatt hour. If there’s enough batteries that that gas doesn’t need to bid in, then all of a sudden we don’t have the gas price that everybody has to pay. We have the battery price that everyone has to pay, and that is very, very cheap and will become cheaper as there’s more of them in the, in the system.

    So it’s like a threshold event. You, you know, um, even if you’re using only a tiny bit of gas, if you need any gas at all, even like, you know, one megawatt of gas, everybody gets paid the gas price. If you just get a little bit more battery in and you don’t need it anymore, bam, the price just falls. So that’s what we…

    We’ve passed that threshold now. 

    Allen Hall: Isn’t that where the UK is trying to get, is to get past that threshold where renewables are that last addition to the grid and kick off peaker plants and some expensive other- fuel sources. That’s I, I [00:16:00] think where everybody’s gone because they have the same system where the, the last one in is what sets the price for everybody.

    Rosemary Barnes: Yeah. The UK’s a little bit different because one, they’re connected to Europe, and two, they’ve got nuclear, so they do have that kind of base load. 

    Allen Hall: Let’s go down the rabbit hole just for a second. So if the peaker plants don’t come on, that means that the battery electricity supplying the grid is pretty low in price.

    It seems like they are losing money on their investment in the battery That they were hoping the price would be higher. Because if the peaker plants are still going on, that would be a $400 price and they’re gonna come in at, like, 350, so that would make sense. It, it helps pay off the battery investment.

    But if they’re dropping the price down from 400 to 100, it would seem like the battery investment may not be a, a wise decision. 

    Rosemary Barnes: For sure they’re making less money, but it was– they were making crazy profits for the first little, the first few, few years of, you know, grid-scale batteries. And even [00:17:00] home batteries, people were making a l- a lot of money off that, and it was crazy.

    Like, I’m on some, um, some Reddit subreddits about, uh, you know, people with home batteries and- 

    Allen Hall: Slash battery? 

    Rosemary Barnes: Matt probably is too. Matt’s a Beta G enthusiast, so I’m sure that he is just as excited as me. But anyway, so on one of these subreddits, you know, people used to talk about, “Oh, I made 100 bucks last night,” um, or, or whatever, you know, just a household.

    And now all the posts are complaining about there’s been no price spikes all year. You know, I thought that I was gonna make heaps of money off my battery, but people are really change- changing how they think of it. And now it’s like… And l- like I want– used to want to do this. I don’t have solar panels yet ’cause we need a new roof, and I’ve been waiting a few years to, one, live in a house that I own, and then two, get a freaking new roof.

    Um, and I thought I’m gonna just, like, cover it in solar panels, get a huge battery, and I’m gonna be an energy trader in my free time and make heaps of money, and now that is [00:18:00] not the strategy anymore. The strategy is to just reduce your bills to the m- the minimum that you can. Um, that’s basically, that’s basically it.

    So you are right that some of this arbitrage is, um, the opportunity’s over, and that it will be less, um, exciting for, uh, opportunity for people to put more, more batteries in. 

    Matthew Stead: Just to add to that, through the middle of the day quite often there’s, uh, negative pricing. So if you’ve got a battery, you’re being paid to charge through the middle of the day.

    So that actually takes away some of the pain from having a lower, a lower price, um, during the peak. 

    Rosemary Barnes: But the thing about negative prices is that you need coal power plants for them to be… Like, the only reason we have such pervasive negative prices is not because solar plants have PPAs that are, you know, make it worthwhile for them to generate even when the price is slightly negative.

    The real thing is that coal power plants don’t want to turn down below, I don’t know, yeah, like 20, 30% during the middle of the day. They have to be on if they want to make money in the evening, and that means that they bid in at, like, [00:19:00] negative 50, um, so that people– so that they can stay running. And that’s where the bulk of our negative prices come from.

    So

    As coal power plants close, those negative prices will go away. Um, and when they close, we should get some better evening price spikes again. So, you know, like nothing ever stays the same for long, which is why it is such a fascinating hobby to have, being interested in the electricity market, because it’s never the same from one year to another.

    You’ll never understand it, ’cause it’s never, it never stays the same long enough to really get your head around it. 

    Allen Hall: You need other hobbies. You really do. 

    Matthew Stead: A friend of mine works in trading, and, uh, he said, “As long as there’s volatility, there will be progress.” So much like what Rosie was saying is the more volatile it is, the more opportunity there is for people to come in, um, and change it.

    Allen Hall: I just don’t know how the battery thing plays out once that threshold is reached. When you have more batteries on the system and you knock down the price that [00:20:00] much, I think battery sales, industrial batteries really slow down because they’re all looking for that quick ROI And they’re not gonna get it.

    Rosemary Barnes: You have to wait for all of the coal to close before you would find out what’s the right amount of batteries to have in the, in the grid. 

    Allen Hall: Yeah, yeah, yeah. That, I totally agree there, yeah. 

    Yolanda Padron: You’d still get, like in extreme weather events and stuff, you’d still get a big price spike, right, for all these batteries.

    Allen Hall: Back to Matt’s point, more volatility. 

    Rosemary Barnes: If you want the market to respond, you need to give enough incentive to invest in assets so you’ll have enough when it’s needed. And because it’s really infrequent, then it has to be a super high price to, um, bring on enough investment. And will this system… The system has worked absolutely, you know, pretty well in Aus- Australia at least.

    Will it continue into the future with more variable prices and renewables? I, I don’t know, and the government is starting to do some things like, uh, you know, like a lot of [00:21:00] electricity markets have, um, not just energy markets but also capacity markets where you will pay a battery or a gas plant something to be on standby basically, um, so that if there is, um, if there’s a shortfall then they, then they have to respond.

    So in Western Australia they have that, but across the east of Australia th- they currently do not, do not have that. It’s energy only. 

    Allen Hall: Really? How do you not have capacity payments? 

    Rosemary Barnes: The majority of their profits are made in just a few hours a year when there are those price spikes, so that’s, that’s h- part of their business case.

    Allen Hall: I mean, there, there is arbitrage happening on the electricity grid. That’s not the best place to be arbitraging things because you will have players that won’t provide electricity just to drive up the price. 

    Rosemary Barnes: Uh, and it happens in Australia too, but, um, you know, because batteries are such a distributed resource, it, it will become harder and harder to do that when, you know, the, um, the ownership of these batteries is, you know, households as well as, um, yeah, as well as [00:22:00] big companies.

    Matthew Stead: So offshore wind, I was talking to an OEM a, a little while ago and, uh, talking about blade repairs for offshore wind, you know, floating, floating wind. Um, so specifically floating wind. The OEM was extremely concerned about floating wind, um, because it makes it very, very, very hard to change blades. So the story was that if you’ve got an offshore floating platform, you’re basically gonna have to tow the wind turbine back to port to change a, a blade.

    Rosemary Barnes: They see that as a, as a pro, not a con though. Yeah. That, that’s because it’s very hard to… Like, it’s not only floating offshore wind where it’s very hard to remove a, a blade out at sea, like fixed bottom offshore wind, that’s incredibly expensive to remove a blade. So floating is like, well, you can just tow it back to shore and then you can do it all in the port.

    I, I, you’re looking skeptical, Matt, and I’m also skeptical about how it actually plays out. I know that, um, what was it? The, [00:23:00] the one- An EOL project off the coast of Scotland. I can’t remember what it’s called now. Like what, the first big one, the big wind farm, a floating offshore wind farm 

    Allen Hall: HiWind Scotland 

    Rosemary Barnes: They had a, a problem.

    I don’t know if it was a serial issue or also, like it’s the first big wind farm, and there might have been like some operating condition they weren’t aware of that caused some problems. They had to tow back everything to port, and they stayed there for months and months. So like maybe, maybe close to a year or over a year, I’m not sure.

    It was a really long time. And so, um, yeah. But then, you know, like what’s the alternative? If that had happened out at sea, it would’ve been more expensive. If, it still would’ve been shut down, not doing anything, and you would’ve had like helicopters out there every single day bringing teams and, um, you know, huge vessels with cranes and yeah.

    So like it’s, maintenance at sea is never good. 

    Allen Hall: But the whole point of the HiWind project was to get some of these problems figured out, and one of them was just towing it back to port and [00:24:00] doing major repairs or component exchanges make sense. I think it’s a, it’s a lesson well learned, and we’ve moved on.

    I guess the question is, does offshore, floating offshore in particular, have much of a future if Norway’s not willing to do it? 

    Matthew Stead: I think it’s a good comparison with, um, data centers in space. 

    Rosemary Barnes: You know where else they’re planning to put data centers? Not just space and offshore, also like, um, underwater ones, like on the deep ocean floor, um, on the moon somewhat.

    Like there’s an actual company that is apparently developing a, a data center on the moon 

    Allen Hall: As wind energy professionals, staying informed is crucial, and let’s face it, difficult. That’s why the Uptime podcast recommends PES Wind magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future.

    Whether you’re an industry veteran or new to wind, PES Wind has the high-quality content you need. Don’t [00:25:00] miss out. Visit peswind.com today. Well, in this quarter’s PES Wind magazine, there are a number of great articles, and if you haven’t downloaded your copy, you should do that at peswind.com. There’s a good article from Global Blade Services USA, and it’s talking about the technician problem and how it’s not gonna, it solve itself, obviously.

    But Global Blade Service is putting some numbers to it. And Rosemary, this is really directed at you. Blades represent roughly 20% of the total, total turbine capital cost and are the leading driver of unplanned downtime. 

    Rosemary Barnes: Yeah, 40% of O&M. 

    Allen Hall: Right, and 75% of all blade repairs are already handled outside OEM warranty.

    That number seems really high, but maybe after the warranty expires? 

    Rosemary Barnes: Do you say 30% of, of repairs are repaired under warranty? That’s, uh, unexpectedly high from my point of view. [00:26:00] But, you know, how would I know? No one’s getting in touch with me if, you know, they’ve got a problem with their blades and it just got fixed under warranty.

    Then they’re not paying a consultant to come sort it out. I only, I’m, I’m only there when the warranty is nearly up or it’s already over. 

    Allen Hall: So they, they’re saying that the, the ratio’s even gonna grow more towards out of warranty repairs. But the problem is having technicians. And the deeper problem is developing all those technicians in time as that need grows.

    Uh, reaching full structural repair competency takes a rope access technician eight to 10 years. A basket technician is five to seven, and a factory technician is four to five years, meaning the workforce, uh, the industry needs for the next decade has to start training now. I, I think we’re seeing this in full force.

    I- the issue is keeping good people in the industry as it fluctuates up and [00:27:00] down all the time and is very seasonal. Because there are really good rope technicians out there who know what they are doing, and it does take a, a minimum of three years to be competent. And then to be that lead person, it takes four or five solid.

    And to be, uh, the, the relied-upon person, especially for some of the more complicated repairs, it’s gonna be six, seven, eight years before you’re there. It’s just an exposure thing. Are we in a technician crisis? 

    Rosemary Barnes: Crisis is maybe a little bit inflammatory, but, uh, we’re in a technician challenge 

    Matthew Stead: But it’s a pretty, it’s a pretty basic topic, Allen, isn’t it?

    Like, um, you know, there’s more and more wind turbines, there have to be more and more technicians. It takes time to train. So, you know, it’s, it’s just, it’s pretty much basic maths and, um, you know, it’s like te- you know, tradies to build houses. Um, you know, unless you’ve got the tradies, you can’t build houses in a cheap way.

    Yolanda Padron: Part of the issue is that, you know, say there’s [00:28:00] 10 technicians that are available in the area, right? Then you … maybe they work under two different companies, and then one company goes bankrupt, so then they all work with the same company. Another company pops up, or someone gets kicked off site from the OEM side, and then a month later they’re back with the third party.

    And then it’s just really difficult to keep track of kind of who’s still there and who’s not, because some people have the certifications and maybe they’re not really, really great at what they do, or other people have a lot of training and a lot of experience, and it’s just difficult to track exactly, you know, where they are now.

    I know that the, the strategy here oftentimes is you’ll find one person that you like and you kind of follow him around, or follow them around whatever company they’re, they’re with at the moment, and then just use that company. 

    Matthew Stead: The other point I was going to make is that there’s also the seasonality, isn’t there?

    So you know, if you’ve got a great, a great technician, when it’s cold, they can’t earn cash from [00:29:00] repairing blades. 

    Rosemary Barnes: Aren’t they hired as, like, seasonal workers in America and they just don’t get paid for part of the year? That’s not how it’s done here. I mean, I guess we don’t have the climate where you have to, like, totally shut down, so they’re not, like, sitting around getting paid for nothing.

    But, like, that’s a really unim- unappealing feature of the of the, um, field, isn’t it? If you’re deciding what you wanna, what kinda job you wanna do, you want one where you can get paid for 12 months out of the year, not just, I don’t know, like eight or whatever it is. 

    Matthew Stead: I know there’s been a lot of discussion between, like, Australian US repair companies of, like, shipping technicians down here during the Northern Hemisphere winter and vice versa, and it gives, you know, chance of exploring the world.

    But, you know, if you’ve got kids and family, you’re not gonna necessarily wanna do that either. 

    Rosemary Barnes: It’s such a tiring job, though. I don’t… Like, there’s, um, I think it’s fine if people do it for, like, a hard 10 years and then, um, yeah, move on to… Because you obviously learn a lot as a technician, so y- you know, like, there’s a lot of office jobs that you would be really good at [00:30:00] because you had that physical experience.

    But yeah, like, I, I do think that there’s heaps of young people that are traveling the world being wind turbine technicians. 

    Yolanda Padron: At least in Texas, I know a lot of rural areas where they don’t necessarily have a lot of opportunities to get higher education, and so going to be a technician is a good route for them to then go into a larger part of the industry, um, to, to kinda get a head start there.

    Um, and they get a lot of really valuable skills, and oftentimes, like you said, Rosie, they’ll, they’ll get picked up by, um, by the owners or the OEMs or someone, um, because of their experience there. But it, but it is quite a bit of, of hard work and, and physical, physical labor. I climbed one tower and I was sore for two weeks, so really, really not my cup of tea.

    Rosemary Barnes: I’m always, like, so excited to, to be climbing towers ’cause I only do it, like, you know, sometimes no times in a year, sometimes twice a year. Um, yeah, so, like, I’m really excited to go climb, and it’s really cool the first day, and then the second day it’s like, “Oh, this harness is [00:31:00] so heavy. Am I really putting this on again?

    Oh my God.” Yeah, so it’s, uh, it’s ob- obviously you get used to it if you, um, if you do climb a lot. The last, uh, last site that I was at, a lot of the technicians were just climbing the ladders so that they wouldn’t have to, you know, go to the gym afterwards. So there’s a lift there, but they use the ladder because then they get their cardio for the day.

    So, you know, they’ve obviously got some surplus energy. 

    Allen Hall: I think it is kind of a myth outside the US, uh, uh, seasonal workers, uh, at least in Europe, I haven’t seen a lot of seasonal workers. It doesn’t mean they don’t exist, of course. But in the United States, there’s a lot of seasonal workers from construction and all kinds of other industries.

    People figure it out And it, it’s a lot more common than I think y- being an engineer you think it is, but there are a lot of seasonal workers. So being a, a wind technician is not a bad job. 

    Rosemary Barnes: I guess they’re just getting [00:32:00] paid extra for the time that they’re working and they just know they’re used to budgeting to cover the few months off.

    Allen Hall: They have a winter job. They’ll, they have employment. They already have it lined up where when it gets cold outside, they have someplace else to go. Back into construction for a few months. They’re maybe driving a truck or doing other things that, that bring in income. They have it pretty well figured out.

    When– At least the technicians I’ve talked to seem to have a, a plan about it, and they’re not sitting by the television for six months. That’s not what’s happening. It, that there’s a lot of employment opportunities here in the States, and so they, they’re pretty nimble.

    Siemens Gamesa Warns Europe, Shell Sells Offshore Wind

    2026/06/15 | 2 mins.
    Allen covers Siemens Gamesa’s warning that Europe is 40 GW short on offshore wind, Shell’s plan to sell its offshore wind farms, Maine’s multi-state bidding round, and Egypt’s grid financing deal.

    The wind industry got a warning this week… and it came from the top.

    Siemens Gamesa, the world’s largest maker of offshore wind turbines, says governments in Europe may be running out of time. The company’s chief executive sounded the alarm Thursday. Europe is currently forty gigawatts short of its one-hundred-and-twenty gigawatt offshore target for twenty thirty. Sixteen gigawatts of projects in Germany alone are at risk of delay, tangled up in lengthy permitting and grid connection backlogs. The plants are running full today. But without new orders soon, factories could go dark for contracts starting in twenty twenty-eight.

    “It is not yet an existential threat,” said Siemens Gamesa chief Vinod Philip, “but it could become one.” He stopped short of predicting shutdowns. But he said the company would likely have to downsize resources if governments fail to act quickly. Europe’s offshore supply chain has already committed fourteen billion euros to meet the twenty thirty targets. That is roughly sixteen billion dollars… with no guarantee the orders will follow.

    Meanwhile… one of the world’s biggest oil companies is quietly walking away from wind. Shell is preparing to sell its offshore wind farms in a deal that could fetch more than one billion dollars. The company has hired advisers to run the process, which could launch before the year is out, with a sale expected sometime in twenty twenty-seven.

    Shell once dreamed of becoming the world’s largest electricity producer. That vision died when its current chief executive took over in early twenty twenty-three and shifted the focus back to fossil fuels and shareholder returns. Since then, Shell has been unwinding its green power portfolio piece by piece. It sold its European onshore renewables arm. It sold Indian renewable company Sprng Energy, which it had bought just years earlier for one-point-five-five billion dollars. And it walked away from planned offshore wind farms in Scotland. When this latest sale closes, Shell will have little wind left in its portfolio.

    But where one door closes… another opens. Up in the northernmost corner of Maine, a region that has sat on one of the best wind resources in the country for years, a long-awaited breakthrough may finally be at hand. The Maine Public Utilities Commission is closing its latest round of bidding for wind and solar generation in Aroostook County, plus the new transmission lines needed to move that power south to the rest of New England. The target: at least twelve hundred megawatts. Enough to power hundreds of thousands of homes.

    Maine is not going it alone this time. Connecticut, Massachusetts, Rhode Island, and Vermont are sharing the cost of the new transmission infrastructure. The previous attempt in twenty twenty-one fell apart. Costs rose. Deals could not be finalized. Landowners fought the proposed one-hundred-forty-mile power line. This time, officials say things are different. The multi-state partnership changes the math. And northern Maine’s wind resource has not gone anywhere. Dozens of energy companies have signed up to compete, from local developers to major multinationals. If everything goes to plan, the best-case scenario puts new turbines spinning in the twenty thirties.

    And half a world away… Egypt is making a major investment to keep pace with its own renewable ambitions. The Egyptian prime minister this week witnessed the signing of a financing agreement worth sixty billion Egyptian pounds, earmarked for the national electricity transmission network. That money will go toward upgrading the grid so it can absorb the solar and wind power Egypt plans to add in the coming years. The target: forty-five percent of national electricity from renewable sources by twenty twenty-eight. The electricity minister said modernizing the grid is a “continuous and evolving process,” and that implementation timelines are being compressed to meet that twenty twenty-eight deadline.

    The wind is shifting. The question is… who moves with it.

    And that’s the state of the wind industry for the 15th of June 2026. Join us for the Uptime Wind Energy podcast tomorrow.

    Gulf Wind Scales Uptower Repairs, Sheds Storm Loads

    Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow

    Allen Hall : David, welcome back to the program. 

    David King: Yeah, I’m so glad to be here. A lot’s happened since the last time I was on, so, uh, this is gonna be great. 

    Allen Hall : It’s been about a year. Mm-hmm. And last year we were at OM&S in Nashville, and you were talking about root fusion, and this is the insert fix uptower for the blade inserts, right?

    So we’re having a lot of blade bolt issues, and the inserts are starting to pull out or become loose, and the blades are moving around. A lot of our operators in the States are trying to solve that problem, and they don’t wanna remove the blades and bring anything down tower. They would like to fix it uptower.

    That’s where your solution came in. How’s that going? 

    David King: Yeah, so I mean, it, it’s really been a five-year journey for us. I mean, we’ve been doing this- I remember that, yeah … for a [00:01:00] very long time. You know, it started like any process does, with a problem statement. Sure. And we’ve been working through from problem statement, you know, going through process development, going through structural development, going through pilots.

    Uh, we did a, a huge pilot deployments about three years ago, where those were being monitored. Um, we’re now in a position where we’re in serial deployment, and that’s what’s really exciting. You know, we’re doing about 200 blades a year, uh, of, of serial deployment. We’ve, we’ve done that now, uh, we’re going into our second year of that.

    Nice. So we’re extremely excited by that. That comes with its own sets of challenges as you scale up. How do you maintain quality? We even touched a little bit on a few of these things last year. Um, but yeah, we’re really excited to be doing that. Uh, we’re trying to keep it, you know, again, process-driven.

    How do you simplify a process that allows you to scale up appropriately, train people appropriately? A- a- and that’s what we’re really excited about this year, is being able to bring this, uh, so that we’re not, um, you know, basically supply constrained, ’cause there is a lot of demand for this, and still able to maintain a very high level of, of quality as we, [00:02:00] we scale up.

    Allen Hall : Yeah, and that’s the key to all sort of repairs in the wind industry. You like to do it once and be done with the life of the turbine. Now, so you’re going uptower. You’re drilling some holes up along the blade, injecting those with a resin system, curing it, basically reinforcing what is already there That all makes sense to me.

    Engineering-wise, that makes sense to me. But a- again, it goes back to the technicians and the training and the deployment of it. Are you starting to train technicians, bring them in, show them how to use the, use the machines and, and get them out in the field so they are ready to go? It, it… ‘Cause it seems like you’re at that threshold now.

    David King: No, absolutely. So we, we believe in people first, right? Yeah. People at the end of the day make things happen. And so, you know, the best ways to do that is give people the right tools to be successful, and where that comes from is training. That’s a huge part of it. We have a, a certified training program that we run.

    Uh, it started out as an internal program we were running. It basically has five levels to it. Uh, we’ve now extended that to, uh, enabling, uh, you know, basically [00:03:00] preferred partners to be able to take part in that training, uh, to be able to utilize modular kits, pumps and equipment, to be able to, you know, go out and meet that demand that’s out there, but do so in a way that’s, uh, controlled.

    Yeah. And so really that comes back to that certified training program. And really, you know, level one is about a lot of your basic safety, procedural base type, uh, you know, making sure people are competent, uh, they’re not gonna get themselves hurt. Right. They’ve got the right personality traits about focus, uh, you know, detail focus and things like that.

    Yeah. Uh, level two to that program is, is really about, um, basically getting people to a stage in which they can be a, uh, team member. Uh, they’re able to be on a team and contribute to that team in an effective manner, be in the field. 

    Allen Hall : That’s really important. A lot of- 

    David King: Absolutely … 

    Allen Hall : companies miss that aspect of being a team member instead of an individual.

    Yeah, you have to work with other people. Yeah. It’s, it’s critical. 

    David King: It’s massively important. Personalities clash. You’ve got to be able to work through that sort of thing. And so that level one to level two is really kind of taking your green horn hat off and putting, “Okay, I, I, I can be on this team and I’m, I’m a, a contributing [00:04:00] member.”

    And then at level three, that’s your team leads. Those are people that are leading teams. They’re leaders. They’re up and coming. They’ve got a career path, career trajectory. Level four is our mentors. That’s the people that are going out there and that are basically qualified to now actually mentor other people in the field.

    Allen Hall : Yeah. 

    David King: And then your level five is train the trainer. How do you grow more trainers so that you’re not constrained on that training factor? And that, that’s kind of how we, we typically run training. 

    Allen Hall : Uh, and Gulf Wind has the ability to do that. I mean, I’ve been to your facilities, they’re impressive, and that’s one of the limitations for a lot of companies.

    They don’t have the facilities to train people, and they don’t have the resources you do. That opens up a lot of opportunities. Obviously, you’re in the composite repair business. You have crews out fixing wind turbine blades. Some of the more complex ones is what I hear. I mean, I hear it secondarily, but I assume that’s what’s happening.

    What are, are the areas that you get called in on to do composite repairs? 

    David King: We, we really do anything that stops somebody else. Okay. So we wanna be there when there’s a problem where you’re like, “I don’t know where to go next. Uh, this is a big [00:05:00] problem. We’re unsure. Maybe there’s a new technology at play.

    Maybe it’s, uh, a carbon spar cap. Maybe it’s something, uh…” You know, obviously the root stuff that’s very complicated. Sure. And, uh, it’s just gonna require a little bit more engineering. It’s gonna require a little bit more rigor, and that- that’s where we say, look, we, we can, whether it means testing something, verifying something, training somebody on a process, developing a process- Yeah

    or just doing something complicated, that’s where we excel. 

    Allen Hall : Well, that- that’s what I hear from the road is, uh, Gulf Winds here and I think, “Uh-oh. You must have a really serious problem because you’re calling in the experts to do the, the difficult things.” Carbon pultrusions, carbon fabric in, in blades today is such a massive problem because it’s not, it’s not fiberglass.

    It’s just a lot more to deal with, and some of the loading issues we’re finding and, boy, it’s just all over the place. They need Gulf Winds Technology to, to come on site to give them a hand. Now, a- as part of the growth of the business, and you guys have been growing. Every year I, I see they’re just… it’s just a little bit bigger, a little more [00:06:00] people.

    I walked on LinkedIn and hiring some engineers and some people to work over the summertime. That’s all great. What’s the structure look like now? How are you trying to organize yourself as a business? 

    David King: Yeah, so we really break down into three different structures. We have our service division, and that’s, um, putting people out there to solve problems in the field.

    As simple as it gets, right? It’s like you’ve got a problem, we’ve got the right people with the right solutions, and they’re gonna go deliver, uh, a result. Um, and then we’ve got an engineering division. That’s about developing problems. It also has a lot to do with IP. You know, things like root fusion, that’s a pat- protected technology.

    Sure. All of our technology, we do a lot of investments in, in, you know, patent protection and IP work, and so that sits inside that engineering division. Uh, it’s how we, we have the smarts of the company kinda sat in there. Uh, it also is what allows us to really get into some of these, uh, kinda juicy problem statements that are a little bit prickly maybe.

    Uh, and we love getting into those and solving them. Yeah. And then the third and final thing is the composite side of things, and that’s the, the manufacturing. That’s that 30,000 square [00:07:00] foot composite manufacturing facility where we wanna be the best in vacuum infusion. We wanna be the best in prepreg, the best in pultrusions, complex assemblies, and be trying to de- uh, just deliver really high-quality composites to the industry.

    Allen Hall : Yeah, and you have the equipment to do a lot of testing. And I think a, a lot of operators don’t realize what you have And the knowledge that’s sitting there, when I run into operators across the country that have complicated issues, particularly if they have carbon, I mean, oh my gosh, you, you need to be calling experts here.

    And if they have issues they haven’t really sussed out, they don’t know, they don’t understand the engineering that went into that blade, they need to be talking to you guys about Why is this blade designed the way it is? How should I approach this? Do I need to be turning my turbines off until I figure out a solution?

    A lot of times there’s not a lot of resources there because the, the designs are more complex than ever. But on the, on the same hand, I would say they’re not doing a lot of testing of their own materials. [00:08:00]

    David King: Yeah, and there’s a huge space for that. And which is crazy. Absolutely. Yeah. It’s, it’s, uh, it’s definitely a gap.

    It is. And we see it as a gap that needs to be filled. Yes. And so that’s where, you know, we, we say you’ve gotta give the engineers the tools to be successful. Sure. And so what are those tools? You know, that could be anything from what does an aerodynamicist need? They might need a metrology scanner. Right.

    So we do 70 million plus point scans of full blades. We’ve done now a full blade scan and, uh, I think we did it in about an hour, which was a, a new record of how quickly you could get 70 million points on a blade. Wow. And then that allowed- Uptower 

    Allen Hall : or 

    David King: downtower? It was downtower. Okay. Okay. It was outside in the field, but it was downtower.

    Okay. It’s still impressive. So that was a little, little, little bit easier than uptower. Sure. Maybe that’s next. Um- Yeah. But, um, no, and then so what can you do with that? Well, then you can go, uh, really analyze, you know, the performance of that blade. Maybe you can go do something in a wind tunnel with it.

    So coming back to that toolkit- Yep … an aerodynamicist needs a wind tunnel. We have aerodynamicists, so we have a wind tunnel. Then going on to, like, a structural engineer. What does a structural engineer need? Well, they need their FE tools. They need some good first principle approaches to, to structures.

    But they also need test equipment. Right. They need to be [00:09:00] able to develop and characterize materials both in static and fatigue. And so we’ve made a lot of investment in those sort of test equipment, uh, so that we can, we can put numbers to things. You know, I think the wind industry needs more data. Less speculation and more data-driven decisions, and the, where that starts is really building up that test base.

    And we, we believe in this thing called the testing pyramid, and what it is is, like, you’ve gotta characterize the material. That’s where you’re gonna have thousands of samples. Right. That’s your tensile, double lap shear testing, all the basics. Then you do your subcomponents. Add some geometry into that, that- Add some shape.

    Exactly. Maybe that’s hundreds of samples. And then you’re gonna go on top of that to, like, your full component. And look, we don’t have a blade test stand yet, but- Right … that’s kind of that, that space. And then the final top of that pyramid is go do it in the field, get results- Run it … and then run that back into your design cycles.

    And I think the more we can do that as an industry, the more successful we’re gonna be as an industry. 

    Allen Hall : Yeah, and I think a lot of operators don’t think they have to participate in that, and they’re sadly mistaken. And the fact that the industry has grown as fast as it has means [00:10:00] there’s some holes in some of the engineering that maybe they didn’t consider the, the site assessment properly or they didn’t understand some of the manufacturing variability.

    Now you own this product, you’re gonna have to do some of the homework that maybe the OEM should have done. It’s your site. You own it. And a lot of times I think, uh, as an owner/operator, they don’t realize there’s resources. Like, okay, well maybe do some mechanical testing. Maybe the repairs I had last summer aren’t working out the way that I think.

    Maybe I need to look at some materials 

    David King: and see if- And we want you to own your data. Well, that’s exactly it, right? That’s really what it comes down to is like you wanna own the data, know your blades, know your products, whether it’s, you know… I know you’re very, uh, you know, uh, specialized in lighting, really know your stuff.

    Everybody’s gotta take that same approach. Know your stuff- You need to know it … or go find the experts that know it- Right … and work with them. Yeah. 

    Allen Hall : Well, at, at this point in the industry’s growth, you realize who’s all percolated towards the top, right? You, you, you see the companies like Goldwind that have the expertise in-house and, and have established themselves as a [00:11:00] knowledge center, as a resource for the US and globally, and there’s only a couple of those spread around the world in that- We as an industry need to be utilizing you more to help us solve problems.

    Because if I don’t tell Gulf Wind what’s going on, Gulf Wind can’t help come to a solution. 

    David King: And we find that really, like, just the more you know, you start finding all sorts of new opportunities. Yeah. ‘Cause we almost learn what you don’t know, in a way. You kind of realize that, like, there’s so much more out there.

    Yeah. And that’s where it gets really exciting. That’s where it’s like you can get these novel solutions, people who take creative approaches. Um, and, and I really think that’s what’s gonna take this industry forward, especially now when, you know, there are some headwinds for wind. And all that means is we’ve gotta get sharper, and we’ve gotta be, uh, more agile.

    And I think it’s actually almost times like this that create some of the best, uh, behaviors in an industry to, uh, take it forward into the future really. 

    Allen Hall : Yeah. Wind’s not gonna go anywhere, but it’s being stressed a little bit. And in those stress points, we need to take the time to reflect and to make the industry [00:12:00] stronger.

    But in order to do that, we need to be relying upon the sources that we have. There are global sources. There are so many resources to touch into. I think you guys are, are doing amazing things. Obviously, being down in your facility, seeing the wind tunnel, just blown away by that. Seeing the mechanical testing, seeing the, the 3D printing of air foils and all that work you’re doing, plus the ability to scan blades, do large scale studies.

    I remember one was on CMS at the time, thinking, “All right. Somebody’s, somebody’s actually doing the right thing. There’s a study happening so we can understand what’s happening in CMS.” Like, those things need to happen as an industry to grow. 

    David King: Oh, absolutely. And I know you and I were at WOMA- Yes … quite recently.

    Yeah. And we heard about that LEP study. Yes. And what a prime example- … of people going out there, getting real life data. Yes. And then, uh, making it accessible so that people can make smart decisions, and again, drive the cost of energy down and make wind successful. It’s, it’s amazing. 

    Allen Hall : It, uh- Yeah. Yeah, yeah.

    But the transfer of knowledge is the key, right? And you guys are involved [00:13:00] in looking at some, what LEP will do to improve a blade, but also what leading edge damage will do to erode performance. Those are some of the things that a lot of operators don’t understand. Like, is that blade being in that damaged form even affecting my AEP?

    It depends on the turbine, I think, a lot of times. But you better be asking the question at least. Talk to somebody who knows. 

    David King: Yeah. ‘Cause it, it’s really interesting. I mean, you know, I think it so much drives back to that business case for the operator, and they all have their own approaches. And, and really- Yeah

    you know, most people are repairing LEP when it becomes structural. That’s the- That’s right … that’s the predominant approach. And, you know, I understand that approach very… You know, I, I get it from an operator’s point of view. Um, but yeah, there’s definitely, uh, other things you could do to try and make a, a data-based business decision.

    Um- Sure. 

    Allen Hall : Sure. Now, what are some of the cool new things that Gulf Wind is working on, that you haven’t announced to the world yet, but you’d like to announce? I know you’ve been working on things. I’ve seen all the white papers being published. There’s some things- Back behind the scenes, what’s new? 

    David King: Yeah. I mean, so, you know, you take something like Roof [00:14:00] Fusion, right?

    Right. Which is a long process to develop. So we, knowing that everything that, uh, you have as an idea is gonna take almost maybe three, four, five years to actually bring to market- Sure … we’re always starting on this constant cycle of development. Right. And so the things- You know 

    Allen Hall : it’s gonna be five years.

    David King: Exactly. Yeah. And so, you know, I mean, it’s like the patents on this stuff take three, four, five years to work out. Yeah. And so it- it’s a very important part of the entire process. Yeah. But to, to answer your question, we do have some exciting things both in the aero side, uh, side of the world. Uh, we have been doing a lot of development work around, uh, basically, uh, passive load shedding, so the ability for a turbine, or actually any structure, to be able to react to the wind in a passive manner.

    Uh, so you don’t need any sort of mechanicals. You don’t need anything, uh, that’s going to break in the field, and the structure itself is able to actually react to the load that’s coming onto it and change its aerodynamic, uh, profile and change its load that it’s experiencing. So you get these… Uh, that’s a very interesting new technology.

    Yes. Uh, it’s something that we’ve been working on for about three or four years now. It’s now, uh, [00:15:00] getting demonstrated, uh, which we’re very excited about. Uh, we also have some technologies, uh, around new connection types between metal and composites. So this is, uh, something that’s, uh, probably got a lot of, um, application in aerospace, but I think it’s also gonna find its way into wind.

    And this is just a new way of really trying to fix some of the problematic joints that we’ve been dealing with now for the last few years, but looking forward, not looking backward. Yeah. Right. Sure. Not being retroactive. Right. But how do we do that next generation of roof pushing design, for example? And we’ve got a really exciting method for that, that, uh, is been tested now.

    We have test results for it, and they look extremely good. Uh, we also are making some major CapEx investments this year into- Sure … new manufacturing equipment. So we have, um, some… I, I would say some, some pretty advanced, um, automation we’re trying to bring to composite manufacturing- Okay … around pre-preg carbon fibers and things like that, which is gonna be very, very exciting I think.

    Uh, I hope it finds its way into the wind industry. It’ll probably start in other industries. Sure. Maybe kind of this, uh, [00:16:00] subsea, you know, and, uh, and air, uh, space first- Sure … you know, around UAVs, ROVs- Sure … that sort of thing. But I think it’s also gonna have applications in wind, and we’re really, really excited about that.

    Well, 

    Allen Hall : that’s good because it, it does seem like wind is downstream of a lot of aerospace things ’cause it does, definitely costs money to develop those, and aerospace is a place where that can happen. However- If you work out all the kinks and you solve all the manufacturing issues, it is directly applicable to wind.

    David King: And it’s massive volume. The beautiful thing about wind is that the volume, when you get something right and you do it right, you get to deploy technology. Yeah. Yes. You, you get to take it off the shelf- Right … and put it in the world and make it happen, which is, there’s nothing more exciting as an engineer.

    Allen Hall : Well, I mean, in, in terms of blade manufacturing, how many times have we talked about automating that so we have less things like wrinkles and some ply issues, overlaps, those kind of things where automation would help, but we just haven’t really refined it enough to i- implement it at a large scale in a blade factory.

    David King: Exactly. And it’s always usually too bespoke, you know? It is. It’s like you solve the problem for the, the 40-meter blade, and now- Right … there’s a [00:17:00] 45-meter blade, and we need all new CapEx. Right. And then it doesn’t, uh, doesn’t scale well. 

    Allen Hall : That doesn’t scale at all. No. Right. So that’s why they haven’t done it, is because they know the next generation of blade is coming.

    It’s another 10 meters longer, and that’s not gonna fit in this building, and doesn’t make sense- We’re in trouble … to buy the equipment. 

    David King: Yeah, exactly. 

    Allen Hall : Right. So it, it, it’s a- Yeah … it’s a constant evolving industry. Now, I, I had looked at your load shedding patent application or patent. Maybe it came out as a patent.

    David King: Yep. 

    Allen Hall : Mm-hmm. Okay. I wanna understand that a little bit since I’m here talking to you now. The load shedding piece was because, uh, you’re in Louisiana, that’s where hurricanes- Come up … every once in a while, if people haven’t read the papers. But the load shedding technology makes sense because now you can deploy wind turbines in places that you otherwise may not do it because of the risk of typhoons, hurricanes, even tornadoes on some level, some odd wind situations.

    You wanna explain what that technology is? Yeah. 

    David King: Really what it’s doing is it’s trying to decouple the, uh, turbine’s ability to protect itself from its requirement to maintain power and maintain [00:18:00] control. So if you have something that relies on electrical hydraulics or anything like that- Yeah … it’s gonna be extremely susceptible to failing, uh, when- Yes

    there’s a grid outage or when you have a battery that fails or, you know, most airplanes require, like, dual redundancy or triple- Triple … triple redundancy because of that very reason, and we just can’t afford to do that in wind. No. And so the innovation then that gets required is you have to have something that’s passive, something where the structure itself has been designed in a way where the laminate is designed in a way where it’s going to not react progressively like a linear fashion as you apply load, right?

    It keeps bending and bending and bending. Right, right, right. But it’s gonna have quite a sudden reaction to a very particular load case. And so that’s what we’ve been able to do is- 

    Allen Hall : Okay … 

    David King: basically construct that laminate in a way where when it, the right load is applied, in this case, that’s the, the hurricane load or the extreme load- Right

    we can shed that load, uh, completely by the structure simply reacting to the load, and that’s very exciting for wind. It has a lot of other applications ’cause- Sure it does … basically allowing you to hinge composites. We now can- Right … with [00:19:00] composites almost in an origami fashion, hinge them any way we want, which is really, really exciting.

    Nice. And we’re excited to bring that now to other areas besides just wind and, and wind will be a key one as well. 

    Allen Hall : Sure it will. Yeah. Wow, okay. That’s cool. I mean, that’s why I follow Gulf Wind Technology on LinkedIn to see all the cool things that are coming out because, uh, if, if you’re thinking about- What’s new, what’s next.

    There’s probably three or four places, honestly, in the world that I rely upon, DTE being one, Fraunhofer being another, and then Gulf Wind Technology. Like, okay, let’s… So they tram for it here. I… Let’s, let’s see what’s going on this week. That’s amazing. And I, I know that as you guys get more experience out in the field and people will start to recognize the name, it’s just only gonna grow to something even bigger.

    So that, that’s fantastic. I know you, you spend a lot of time making 

    David King: this business go. We’re de- definitely very excited about it. Yeah. But with, with growth comes, you know, a, a discipline. Right. You have to be very disciplined. Yes. And so that’s something, you know, we’ve gotta be very focused on. Yeah. That’s where things like that certified training program are important.

    Yes. It’s where [00:20:00] how we patent things is very important. Yes. How we, uh, you know, kind of set up company structure is very important. So I know we touched on a few of those subjects today. Yeah. But those are really just about trying to be able to maintain quality as we grow. A- and that’s really important to our customers, it’s important to us, and it’s how we maintain the brand.

    Allen Hall : We gotta get back down to Louisiana. I’m really curious to see what’s happening inside the buildings and see where you’re at, because, uh, I know there’s great things happening there. And I really appreciate the time. Thank you for coming over to Australia. I thought your, your talks and your, your presentation and being on panels in Australia was really insightful to a lot of Australians, because you’re just bringing a different viewpoint into that marketplace.

    And, and that’s what Gulf Wind does. So I, I appreciate all that effort. And, uh, yeah, we should connect up this summer. Come down and check out what’s going on. 

    David King: Absolutely. If you’re willing to brave the heat- Oh, no. … you are always welcome. And our aim is that every time you come to that factory, hopefully it’s like a, a whole new world.

    We wanna surprise you with something new, because, uh, that’s the only way we can demonstrate progress. 

    Allen Hall : Oh, that’s a deal. 

    David King: So. 

    Allen Hall : Okay, great. Well, thank you, 

    David King: Dave. Great to see [00:21:00] you. Thanks 

    Allen Hall : for being on the 

    David King: podcast. Thank you very much.

    Allen Hall: 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

    Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Rosemary Barnes, Matthew Stead, and Yolanda Padron. And three out of the four of us, everyone except Rosie, went to Houston this past week. Matthew, you were on the floor. Yolanda, you were on the floor this week. What did you think?

    Matthew Stead: I think there was a few sort of common themes that I picked up. One, the obvious one which keeps coming up every time is insurance and lightning, and insurance, and all those sort of things. probably the other point that I observed was really strong supply chain. they had everyone, all the people, e- even people, building boxes.

    And [00:01:00] so they had boxes, transportation, cranes, really strong, supply chain. also really strong on the batteries, like the CATL batteries, et cetera, et cetera, and solar. I think that seems to be getting a bit more, a bit more, mature and more obvious. obviously blades, lots of people talk to us about blades, maybe ’cause we talk about blades.

    But, lightning root issues, blade bolts, those sorts of things, leading edge erosion, robotic repair, et cetera, et cetera. a bit about, add-ons like PowerCurve, were fairly visible, so that was good. but there was a lot of secret meetings in rooms away from the actual event.

    so that was one observation. and the other observation was perhaps not so many operators that actually [00:02:00] work on a day-to-day basis. That was my subjective impression 

    Rosemary Barnes: Speaking of secret meetings in rooms, what were you guys doing around the time of ACP? 

    Matthew Stead: So the Australian American Chamber of Commerce organized a special event, with two Australian companies to launch a new product, which monitors lightning and then transmits the results using satellite communications.

    So it was very open, but invitation only, Rose. 

    Rosemary Barnes: I, actually, I- the comments, ’cause people are always, after our first go organizing wind O&M event in Australia, I would hear about it from people who didn’t, just chatting at, on, different wind farm sites. They didn’t know I was involved, and they’re like, “Oh, yeah, there’s a secret event now.”

    And it’s we did our very best to publicize this, the most that we could. It was not intended to be secret. So yeah, I’m just wondering if, people are gonna think the same if [00:03:00] they, they missed out on, your event. But how was it re- received? Do, we need more events in the US? 

    Matthew Stead: Yes, absolutely.

    And I, I don’t have my pin on here, but, yeah, I do have a pin from the Australian American Chamber of Commerce Texas division, 

    Rosemary Barnes: How was the event for you, Yolanda? 

    Yolanda Padron: It was good. It was good. the showroom was the, or the exhibit floor was a little bit em- more empty than I thought it would be, but it was good.

    It was good to, to see people, to catch up with everybody. There were some really good chats happening everywhere. and I got … I don’t know about you guys, but I saw a lot more people not from the US that wanted to come in and understand the market better than I did other years, which was nice to see.

    Matthew Stead: Was there any new technology on the floor this year? I thought there was a new robot company, but it was actually solar cleaning. 

    Yolanda Padron: I saw some rebranding from some companies, moving from former ties to [00:04:00] OEMs just m- moving into their own little companies and stuff. in a very interesting, PR move, a, an insurance company was raffling a motorcycle, which was really, funny for us to see.

    Allen Hall: Not very safe, is it? 

    Yolanda Padron: Was 

    Rosemary Barnes: it at least an l- an electric 

    Yolanda Padron: motorbike? 

    Allen Hall: Rosemary, you’re in America. 

    Yolanda Padron: I don’t know very much about bikes, but it was big and scary for me. did I put my name in there? Yes. We’ll see how that turns out, but 

    Rosemary Barnes: I’m always trying to win Lego sets at, events and, try to sweet talk the, the stall managers or s- stall minders into “Oh, if somebody wins and they don’t show up, could I have it?”

    yeah, so far unsuccessfully. Although I do have, actually you can see I’ve, I’ve got a Le- a L- Lego, in inverted commas, not Lego TM, wind turbine that we’ve just started making. So that’s a, [00:05:00] or a tower for a… that we have created. I have succeeded in getting some sort of Lego for my podcast background.

    Allen Hall: Are you gonna buy the Sagrada Família Lego set that just appeared? 

    Rosemary Barnes: I haven’t. I’m not like the hugest Lego fan. I wouldn’t call myself an, what is it? AF- AFOL, adult fan of Lego? Is that what, There’s a, there’s an acronym. I’m not one. None of us are apparently. 

    Allen Hall: Oh, I don’t know. I think we’ll buy that one.

    Allen, does it take 200 years to make? Probably. I think there’s around 10,000 pieces. that’s what I re- recall. It, there’s a lot of pieces. It’s built in sections. I watched had a little discussion about it. It is really complex, but we may purchase one and put it in the lobby of our shop because that cathedral is protected by strike tape, some of the ornamental features at the top.

    So we’ll, probably build one, but it’ll, it will take a year

    [00:06:00] Delamination and bondline failures in blades are difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. CIC NDT are specialists to detect these critical flaws before they become expensive burdens. Their nondestructive test technology penetrates deep into blade materials to find voids and cracks traditional inspections completely miss.

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

    Let’s talk about American Clean Power’s, first quarter 2026 market report. So the American Clean Power Association’s first quarter 2026 market report shows United States developers brought 6.4 gigawatts [00:07:00] of new clean power online in Q1, but overall capacity was down 17% year over year, the weakest quarter since 2023.

    Onshore wind took the hardest hit with less than 500 megawatts installed, the slowest pace since about 2018. the Department of Defense delayed approximately, 165 projects totaling 30 gigawatts and $54 billion of investment. Ken Young, the CEO of Apex Clean Energy, put it plainly, quote, “This DoD thing is real.

    They found a button to hit, and we got punched in the face.” Unquote. Developers won a preliminary injunction in Massachusetts federal court, but the Interior Department has pledged to appeal in regards to offshore wind. Is this gonna be a permanent setback, Matthew? You think this is gonna continue on, or will this eventually get wrapped up and wind will be back on track?

    Matthew Stead: If I wanted cheap power, I would be building wind, [00:08:00]battery, and solar. So I think, if people want cheap power, it, will definitely come back. That’s my view. 

    Allen Hall: Yolanda, you see some of the development. You’re close to it in Austin, Texas. What are you seeing on the ground there? I think there’s repowering going on, but is there much in terms of new development?

    Yolanda Padron: There’s repowering. I think new development slowed down a little bit than this time last year, but it’s still going on, both for wind, solar, and battery, which is good. on the ground level in some of these very rural towns, this is a very important source of income for a lot of those people, regardless of political affiliation.

    so it’s important for some of these people to get these on their, in their land. 

    Allen Hall: Does American Clean Power have a plan to try to address this situation? Are there any lawsuits in place or any legal action on the docket? 

    Yolanda Padron: Not that I know of. I, know there was a, there was that lawsuit end of last year, for offshore.[00:09:00]

    but from American Clean Power itself, I don’t know of anything off the top of my head. Do you guys know? 

    Allen Hall: I haven’t seen much of a roadmap from American Clean Power on this particular issue on the onshore wind. I haven’t seen much e-except but for a couple of summary pieces explaining what is happening on the ground, but n-no action to push back.

    And maybe there’s some lobbying going on with Congress people and, senators, but you think we would hear about some of it. I haven’t heard anything, and I’m watching pretty close. it is a little confounding because it does seem like this could be broken with one court case. Maybe not. Maybe it’s more difficult than that.

    Yolanda Padron: I don’t know. There’s always a lot of, yeah, there’s always a lot of lobbying going on by, not just by American Clean Power, but by a lot of these larger owners, right? A lot of them have some sort of office in DC

    and people coming in and out and going to meetings [00:10:00] with everybody, So I don’t know. I’m also very curious to see what goes behind the scenes for that political side of things. 

    Allen Hall: just as a quick aside, one of the discussions I was having during the week was about AI data centers and the push for power.

    If gas turbines aren’t available for a couple of years and they’re gonna… the administration’s gonna push back on renewables, AI data centers are gonna have a hard time getting the power they need. I know the administration wants them to, be powered by natural gas, but that’s not possible right now. I don’t see how this ends easily.

    Rosemary Barnes: It seems like e- everybody’s looking into any single way that you can power a data center. There are people making serious plans to do it. There’s obviously, we’ve talked about space-based data centers before. then there was a podcast I listened to this week. Allen, you actually suggested it to me, but it’s one that comes up for me anyway, Catalyst podcast about, [00:11:00] data centers on ships.

    It, actually isn’t just purely about data centers on ships. It’s about, this company, and they have a ship that’s designed to fairly passively capture energy from waves of a ship out on the o- open ocean. They’ve actually designed the shape of the hull so that it is, will actually capture energy.

    They choose the location of their factories very carefully, put it in the ocean where there’s already enough energy, and it just, phew, off it goes, just powers itself off to the, I think it was somewhere in the South Pacific, where there’s nice big fetches of, of water and power whatever, including data centers.

    But I think each ship was about a megawatt or something like that, so you’ll need a lot of them. And then wasn’t there one that you were, you wanted to bring up today, Allen, an, underwater data center? 

    Allen Hall: The one that I think you’re talking about is Penthalassa, which has recently come out of the dark mode, and they have been working on this, in at least a couple of years from far as I can tell, [00:12:00] trying to develop data centers that…

    using a, system driven by not necessarily the waves. It’s not the waves, Rosemary. I think it’s more to do with the pressure, of the ocean. It’s, something to that effect, which is really interesting. but, China has, like in many things, working offshore and trying to get data centers up and running.

    they’ve commissioned the first undersea data center powered directly by offshore wind. The Shanghai Lingang project, built by a subsidiary of China Communications Construction, CCC, began operations off Shanghai’s eastern coast in May. Planned capacity is 24 megawatts, and the core design transmits offshore wind power directly to submerged data modules via subsea photoelectric composite cables.

    I’m not sure what that is, but I’ll have to dig into that deeper. And by bypassing grid routing entirely. Seawater obviously will serve as the cooling medium [00:13:00] through circulating pipes in the heat exchangers, reducing electricity consumption by about 20%. one of the local v- university professors estimates that this kind of data center model could save about 50 billion kilowatt hours annually across China’s data center fleet, equivaling, equivalent to not burning 15 million metric tons of coal per year, and that would be nice.

    Is there a future in offshore data centers that use the ocean to cool themselves and Plug ’em into wind turbines offshore, just get the electricity straight from the wind. Does this have growth futures, 

    Matthew Stead: particularly in China? I love it. I think it’s absolutely fantastic, and it just means you don’t have to send them into space, because that’s a silly idea.

    The other point, do you remember a couple of years ago they were going to build, hydrogen electrolyzers, offshore n- next to wind turbines? So all they do is [00:14:00] just scrap the electrolyzer and then put in the data center. It’s just perfect. 

    Rosemary Barnes: But that’s what this, ship one that I was, I listened to the podcast of, that’s their, thing.

    It’s just power for whatever. whatever, obviously it has to be something that’s capable of, operating on a ship environment. You’re not gonna be doing probably precision manufacturing or anything out there. But, apparently failure rates for, data center stuff is not…

    They’re not expecting it to be higher. Higher in some types of failures will be higher, and some will be lower, but, they think that overall it’s so much, so much cheaper. But yeah, they did also talk about doing, yeah, I don’t know, hydrogen. Is anybody, is anyone still talking about hydrogen anymore?

    I feel like we’re finally, not n- not doing that. 

    Allen Hall: Rosie, I think you killed it. I’ve seen more news reports about it, where they’re not proceeding and there’s been some funding challenges, and those things are happening. Like any new technology, it’s, hard. The beginning is hard. 

    Rosemary Barnes: But, you know that, already hyd- making [00:15:00]hydrogen the way that we make it today is something like 2% of the world’s, emissions.

    So it’s okay, we do need heaps of clean hydrogen for that 2%. So I’m definitely not against, some hydrogen projects happening, ’cause we’ve gotta… That’s the, same size as y- you know, nearly as much as aviation, for example. so not insignificant. 

    Matthew Stead: Yeah, someone actually came up to us and s- I had a bit of a discussion about that, Rosie.

    We’ve got a bit of information to share with you about that- 

    Rosemary Barnes: Oh, yeah … 

    Matthew Stead: that will dispute some of your claims. we’ll share that with you 

    Rosemary Barnes: offline. They’re not my claims. I’m merely reporting what people who are working on it say. But I, was saying to Allen, ’cause we had a big chat offline about contrails and how challenging it is to just alter an aircraft’s path to reduce them, I need to, Engineering with Rosie video on this and get an expert on and ask them all of Allen’s very informed questions.

    maybe I’ll get you on as a co- co-interviewer. I’m actually keen on viewer input, listener input. we’ve got a, Pardalote actually has a training course [00:16:00]coming up. I’ve been trying to organize this training so that I and my employees can learn more about blade repairs. So we have a course coming up, organizing it in collaboration with Direct Wind Services.

    We’ve got a great, blade repair guy who’s gonna be taking the course- It’s gonna start out with an optional day that I’ll be running about blade design, manufacturing, certification, those sorts of things. And then three days on blade repair. So we’ll go through the theory, also, hands-on stuff.

    So we’ll be doing grinding, we’ll be doing layups, infusions, all that sort of thing for three days in Ballarat. but the extra cool part is that I’m gonna be using this opportunity to make a video about wind turbine blade repairs, ’cause, one, I’ve been si- trying, I’ve wanted to make a video on this ever since I started my YouTube channel, six years ago.

    So this is the opportunity that I can take to, talk about what kinds of repairs are actually done. I think people will be really surprised to see, even in, when they’re brand new out of the factory, they still gotta do, dozens of repairs on a [00:17:00] blade before it’s ready to go out.

    And people will also probably be surprised at, the extent of, repair that you can do and get a blade back up to its original design intent. So I would ask, anyone listening to this that has questions about those sorts of topics, let me know, and I’ll try my best to include that in the video.

    ‘Cause I think it’s a topic that’s not, super well understood. 

    Matthew Stead: Can I come along as well? 

    Rosemary Barnes: Nice, nice segue into me advertising. So this is our first one. We’ve got, we’ve got a few spots. I think that they’re gonna very easily fill, but we are planning to run them periodically. So yeah, you can get in touch and, let me know.

    yeah. Anybody. You, Matt, I’ll send you over the, the information. 

    Yolanda Padron: That’s a really good idea, Rosie, ’cause I feel like a lot of people, you either have, a really robust, understanding of blades and a really good background on it, or you’re starting fresh. And when you’re starting fresh, it’s really difficult to know what exactly you’re [00:18:00] doing.

    Or you know in theory, not until you go into the nitty-gritty or until you watch Rosie’s videos, do you then get a better understanding of everything that’s going on. 

    Rosemary Barnes: Yeah. It’s, a fascinating topic. obviously that’s what I spend 90, 90%-plus of my time working on. yeah.

    Blade damage and blade repairs. But there’s so much, there’s so much information that would be better off if it was shared, if everybody, knew a bit more about what, what was possible, what was normal, what’s best practice. Then I think that the, O&M for blades would go a lot more smoothly.

    Allen Hall: We had Matt Sagala on the podcast this past week, and one of the items he was talking about, some of the basic fundamentals of repairs, the little checkpoints that need to be in place when you’re looking at a repair, and the photographs that come in a repair report and some of the details, how they get skipped.

    And there should be more emphasis on some of the basics, and making sure that the photos show the different layers that have been ground, where each of the plies are. [00:19:00] Something simple like that, which in a lot of good blade reports. You don’t necessarily see in all of them and Rosie, if you’re training people up and showing them what the fundamentals are, that’d be really helpful in getting that information out where you can access- where it’s accessible, like on YouTube.

    Rosemary Barnes: I’m always giving that, that feedback back, “Can you please at least show, an image of what it looked like before you started repairing?” Nobody ever does that, and it’s y- we have the inspection, the drone image, but, you don’t have… you had, you were right there. You had the opportunity to take the , photo from every, angle, because you wanna be able to recognize what does this damage look like the next time that we see it.

    What’s it gonna look like in a drone image? And, yeah, be able to… sometimes you get in there and you think that you’re just gonna be repairing a couple of layers, and it turns out to a huge, thing. like I’ve seen repair , repairs come in that, hundreds of thousands or more, to do just one repair that was totally unexpected by the person who was paying the bill.[00:20:00]

    the more information that you take about that repair, then the more possible it is for engineers like me to be able to, a- at least predict, okay, you’ve, you’re likely to have a big repair here, and plan for it. 

    Allen Hall: Trying to find someone doing blade repair correctly on YouTube is hard to find.

    It really is. I s- you see people with grinders and things, and yeah, they’re working hard and they’re doing a job. But someone to actually walk through from beginning to end, and made it, and explained it as they did it, would be helpful to the industry. Tremendously helpful. 

    Yolanda Padron: Just to make sure that your budget’s right, for the year.

    if you’re on the owner’s side, and then you think, “Oh, okay. Sure. this AI-based drone inspection told me that I need to tackle all of these, and I know that these are gonna cost me, I don’t know, X amount of dollars,” you can, take a, human pass through those images and make sure that, your expectations and your reality is, closer, just by [00:21:00] looking at Rosie’s videos.

    So that’ll be, really exciting. 

    Allen Hall: Rosemary, how do people join in on your blade repair fun? 

    Rosemary Barnes: for, first of all, get in touch if you wanna do the course, especially in Australia. we could definitely organize one. In, the US coming up, piggyback off a- another event or somewhere else.

    But also get in touch with me at pardaloteconsulting.com, and you can, yeah, send me a message through the contact form and let me know that you’re interested. Maybe spell pardalote, 

    Yolanda Padron: though, for people. 

    Rosemary Barnes: Pardaloteconsulting.com. P-A-R-D-A-L-O-T-E and then consulting. 

    Allen Hall: As wind energy professionals, staying informed is crucial, and let’s face it, difficult.

    That’s why the Uptime Podcast recommends PES Wind Magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future. Whether you’re an industry veteran or new to wind, PES Wind has the high-quality [00:22:00] content you need. Don’t miss out.

    Visit peswind.com today. in this quarter’s PES Wind magazine, which you can get at peswind.com, there’s an article from Minerva Energy, ABJ Renewables, and Concept X where they have developed a product called WindView, which is an advanced inspection system using high-res optical capture with thermographic analysis for a full subsurface, inspection from rotor to tip.

    the system detects defects as small as three to four millimeters, which is quite small, and a- analyzes the blade structures up to about 15 centimeters, which is quite deep, so that it does seem like a pretty useful inspection tool. as we all know, just the generic, visual drone inspection can give you an idea of what’s happening on the surface, but a lot of the structural issues are deeper [00:23:00]inside the blade, so thermal inspection combined with optical inspection can give insights into some places that otherwise go unseen.

    And Rosemary, as a blade expert, and Yolanda too, there’s a lot that happens inside of blades, and having a- an additional tool to inspect blades and to get more understanding of what’s happening underneath the paint service could be really useful. 

    Rosemary Barnes: Yeah, I’m always trying to recommend th- this. I haven’t got any clients that have actually used thermal imaging, to look for damages, but especially in, areas where you suspect that there are r- some repairs that haven’t been done correctly or you’re looking for early signs of a serial defect.

    Y- like one of the weird things with the full service agreement, actually it’s probably true with, yeah, any kind of turbine sale, is there’s this serial defect liability period, and you’ve got to hit usually, a crazy high, stupid high number, like 20%, 30% of all your blades have to have the [00:24:00] same damage within it might be a two or three-year period, not, very long.

    It’s better when it’s more like 20% in five years. That’s, enough time to actually catch things. But so one of the things that you’ve got to do is like you really want to catch things early in order to be able to, y- make a claim on that. And so this is one of the tools that people would have to catch things earlier, like it’s not yet visible, with a crack on the surface that– Or even, like even small cracks on the surface will fly under the radar as well because, they won’t be flagged in the inspection reports.

    So if you’ve got a few of something that’s looks like it might be the same, it, and you’re still within your defect, your serial defect liability period, it’s definitely worth doing something, the, some kind of NDT, and this, is one of the good options it’s actually worth spending a whole lot of money to, to try and get that in because, like the numbers are, millions and millions of dollars, maybe tens, maybe hundreds, depending on, the extent of the problem.

    So yeah, it’s always good [00:25:00] to be well aware of what your deadlines are and what tools are available, and this is one of the good ones. 

    Allen Hall: Yolanda, you think it’ll open up access to carbon pultrusion inspections on blades without actually cracking the blade open? 

    Yolanda Padron: Hopefully, yeah. in, internal inspections you can only go so far, right?

    And Rosie, you have a lot more experience with this in action than I do. but yeah, so I, I think it’d be really interesting to see just what, what people can get done without actually happing- having to go and carving everything out, and without having to already start a s- a, a repair that maybe you don’t have the budget to do.

    Allen Hall: If its speed is fast enough, I- thermal imaging can be slow at times, but from what I’ve seen, the, cameras have really improved over the last couple of years. If they have this down where you could really inspect blades quickly, it would be a tremendous help to have insights into [00:26:00] depth of damage, especially with c- I think carbon pultrusions are the one that we just don’t have a lot of oversight with, and it’s very difficult to inspect.

    And so if you could actually see damage to the pultrusion ahead of time, that would be a, major advantage. I, can’t imagine the insurance companies wouldn’t love this system. S- 

    Matthew Stead: it’s interesting. Yeah, I’ve got a question. GE Vernova has a patent around some of this, technology. They’ve had it obviously for many years.

    But, I know one of the challenges with the GE Vernova approach was that through the day, if you’ve got ambient temperatures, it was a bit hard to pick up, the actual damage. So at least for the GE, solution, it had to be done at dusk or, when the sun wasn’t out. So I don’t know the answer to that, but is that one of the technical challenges around, when it can actually be taken?

    Do you need to take it when the sun’s not out? 

    Allen Hall: Yeah, I wonder that too I’ve– The way I’ve seen it is they try to catch it at sunrise or sunset where there’s [00:27:00] a thermal gradient on the blade. However, the thermal imaging cameras is, are, cameras are so much better than they used to be. it may be possible to just do it during the daytime.

    Rosemary Barnes: I think the different companies are approaching it in different ways and, I’m sure that some of them can do it, like especially under direct sunlight, then that can be actually a really good way to get some, some heating. And then g- it relies– Mostly it’s relying on the fact that different materials heat up at different rates.

    So as long as you’ve got some sort of change in, in temperature happening, then you should be able to see. Yeah, like obviously if there’s a big, crack or a delamination, there’s some air there that’s gonna heat up differently than the composite around it. 

    Allen Hall: Oh, sure. Yeah. 

    Rosemary Barnes: Yeah. I think also like when cracks propagate, they are actually generating some heat at that site and you, can catch that too.

    But, I’m, actually not on top of it enough to know how much it’s one or the other. I think it’s mostly about, when a blade heats up, air will heat up differently to, to composite and you’ll be able to see it. that’s my limited [00:28:00] understanding anyway. Something worth more of a deep dive.

    I’m actually looking forward to some, hopefully some clients getting over the line to, doing some more of the, taking advantage of some of the NDT tests that are, available because it can just help you do such a better job of, management and huge risk redus- reductions too.
