The Uptime Wind Energy Podcast brought to you by Strike Tape, protecting thousands of wind turbines from lightning damage worldwide. Visit strike tape.com. And now your hosts, Allen Hall, Rosemary Barnes, Joel Saxum and Yolanda Padron. Welcome to the Uptime Wind Energy
Allen Hall: Podcast. I’m your host, Allen Hall. I’m here with Yolanda Padron and Joel Saxum.
Rosemary Barnes is on holiday. We’re here to talk about the TPI composites, uh, bankruptcy hearings, and there’s been so much happening there behind the scenes. It’s hard to keep track of, but we’ve done a deep dive and wanted to give everybody at least a highlight of what has happened over the last couple of months.
So, uh, if you do own vessels or GE turbines, you understand what the situation is. As we all know, TPI composites, gee, was the world’s largest independent of wind blade manufacturing. Uh, they [00:01:00] were, it, they built blades for renova, Vestas, Nordex. They built blades for almost everybody, uh, names that basically power the global energy transition.
And then, uh, if, and a lot of people don’t know this, but back in December of 2023, uh, TPI struck a deal that is drawing some fire. Right now, TPI swapped $436 million in preferred stock for. $393 million in secure debt held by Oak Tree Capital and by August of last year, just a couple of months ago, TPI filed for Chapter 11.
Now the Blade Makers assets are being carved up and sold, and two of wind energy’s biggest players are stepping in to keep production running while the bankruptcy plays out. Now, Joel and Yolanda, I, I think the bankruptcy of. TPI sort of came to the industry as a little bit of a shock. Obviously [00:02:00] the, the price had fallen quite a bit.
Uh, if you’ve watched the stock price of TPI composites had been dropping for a while and didn’t have a lot of of market value. However, uh, GE and Vestas both have manufacturing facilities basically with uh, TPI composites and, and needs them to produce those blades. So the filing of the bankruptcy, I’m sure was a nervous point for Vestus and GE being really the, the two main ones.
Joel Saxum: Well, I think we talked about this a little bit off air. Is it, it shouldn’t just be Vestus and GE nervous about this now. It should be every operator that’s in either in development or still has blades under warranty. Uh, so, and this is a not a US problem, this is a global problem. ’cause TPI is a global company that serves, uh, global industry all over the place, right?
We know that a large percentage of their throughput was GE and Vestas, but also Siemens ESAs in there, you name it, right? The, any major operator’s gonna have some blades built [00:03:00] by TPI or op major, OEM. So. There isn’t gonna be much of a, uh, dark corner of the wind industry that this issue doesn’t touch. So I think they, the, one of the issues here is, um, we’ve, we’ve, we’ve heard about some issues going on with TPI, but it was almost like a, ah, they’re not, they’ll, they’ll be okay.
They, so, so something will happen. I mean, Yolanda, you had said. What was it that you said ear earlier? Like, uh, the kind of the, the, the feeling about it.
Yolanda Padron: They’ll take care of it. You know, OEMs will take care of it and we’ll be fine.
Joel Saxum: Someone’s gonna support this thing.
Yolanda Padron: Yeah. I, I think teams, you’re, you’re definitely right.
Teams really do need to at least think of a, of a plan B or a plan C to have when the dust settles so you’re not scrambling.
Allen Hall: Yeah. And it hasn’t really played out that way. Uh, Vestas has stepped in a little bit and GE has stepped in. Not in terms of acquiring any of the major assets, but I think the first question is what is Oaktree Capital’s, [00:04:00] uh, role in all this?
And that is being played out right now in front of the bankruptcy court. Uh, so when you go to bankruptcy, there’s obviously a lot of oversight that happens there, uh, and. When TPI composites entered bankruptcy, the accreditors committee had a bunch of questions about that transaction. Uh, they pointed to a December, 2023 refin refinancing deal with Oaktree and in which creditors were really suspicious of basically saying that TPI was already insolvent in 2023 and Oaktree exchanged equity for secure debt jumping ahead of everybody else in line to get paid.
So because they Oaktree has secured debt, they’re first in line to get paid. If, uh, weather Guard was involved selling parts to TPI, which thank goodness we weren’t, we would be unsecured. They wouldn’t have to pay us. So Oaktree would get paid first and everybody else is unsecured, gets paid [00:05:00] later. Uh, that’s okay.
I mean, that’s the way they, uh, they structured it. But this has led to a problem, right? So that oak tree. Uh, was supposed to release about $20 million in funding to keep the factories open, and that, that happened just a couple of weeks ago, and Oaktree refused to do it. So the amount of cash flow to keep the factories open was a real issue.
TPI was in front of the court saying, we’re in trouble. We’re gonna become insolvent. We don’t have cash flow to keep the doors open. So the blade factories nearly shut down a couple of weeks ago. However, there was a, the settlement, uh, just after that, uh, in regards to Oaktree about when the payouts happen, what Oaktree will receive, and which basically it’s, most of whatever’s gonna happen here.
So whatever, uh, TPI decides to sell or can sell, Oaktree is gonna be the recipient of those funds for most of it. I think the
Joel Saxum: difficult thing here for. The [00:06:00] general listener, me included, is understanding that this is a very complicated legal process that’s governed and it’s global, right? So it’s governed in certain court systems in different places.
And because there is also the idea of like say in the, in the United States, the SEC Securities Exchanges Commission, that kind of regulates these. Publicly traded companies. There’s a lot of lights and there’s a lot of lawyers and there’s a lot of jargon involved in this thing. And, but basically what what we’re saying is, is the way the process works when you have a, uh, a bankruptcy and insolvency, if a company has debt to certain people, there may be a list of a hundred people.
There may be a list of two, doesn’t matter. There’s certain classes of debt, right? And Oaktree has secured debt, which means. If they get paid first, if there’s anything, right? If this bankruptcy goes and, and gets, sell this, sell that, sell this, whatever’s left, goes to the secured debt and then it goes to unsecured debt.
And [00:07:00] there’s sometimes there can be different classes of unsecured debt as well. And, but if there’s not, some of it just goes by like date or value or everybody gets a percentage, it just kind of all depends on how it works out in the specific court system that the stuff takes care of. But that person.
That is the top. Um, in this case, Oaktree Capital, right? Based out of la but offices all over the world, they got about $200 billion in real estate equity and debt assets or, uh, I guess valuation. I wouldn’t say assets. Um, they are the debtor in possession, so they’re the one that’s kind of like top of the heap.
They’re kind of controlling how the. The restructuring and or sale goes alongside the court system.
Allen Hall: And the trouble is, is that when you have unsecured and secured debt, everybody that’s unsecured wants to get paid. So any material supplier that has been for in selling product to TPI over the years [00:08:00] usually has a 30, 60, 90, maybe 120 days of, of after they deliver the product to they get paid.
In that timeframe, if bankruptcy happens, all that product that’s sitting on the floor at TPI, you sort of lost it. You know, you can’t get it back and you’re not gonna get paid for it for if, if, if ever, what do you do? And so you start, you know, you start filing claims, but those, those claims most likely will never get paid.
Or if they will, they’re going to get pennies on the dollar.
Joel Saxum: Yeah. And I would imagine like, so, you know, when we, when we sit here and say from the weather guard hat, right? We put a. They go to a client, net 15, net 30, we expect to get paid in that amount of time. That’s kind of how our, basically US forwarding credit to someone else.
That’s how it works. And if you work within the wind industry, you know that the OEMs, because they are the OEMs, they have a heavier hand. Sometimes they’re net 90, net one 20. Um, once they, once they’re cool with your invoice. So you could see that some of these people that have, [00:09:00] uh, and TPI falls within that OEM category, right?
Um, you can see that they more than likely will have had longer, more favorable terms for themselves with some of these sub-suppliers. And the sub-suppliers are, think about TPI blades. It is composites, it is fabric, it’s resins, it’s all of those supply companies. Um, and you know, there may be, uh, some other.
Dead in there that you’re not, we’re not sure of. We saw some stuff with some OEMs, maybe they have some exchange agreements you paid up front for some blades or something of that sort. You didn’t get ’em. I don’t know. But there is also, and this is the one that kind of hits home to some of our listeners, um, not only some of our listeners are those supply chain companies that support them, um, but a lot of them are ISPs.
Right? So we were just talking to someone who, you know, just a couple weeks ago that had done some inspection work, uh, for, for TPI that. They’re not gonna get paid for it. Um, we have seen on the creditors list of some ISPs that we know they’re not gonna get paid, and those are people out [00:10:00] doing warranty repairs and those kind of things over a course of time.
And they may have had a net 30, net 60, net 90 days payment, but I’m sure that stuff is well and long gone. They probably have invoices due for a year now. Uh, but it, this, the, the, this downfall of TPI, what’s going on with them, it affects a lot of people in the wind industry. Um. Be being, having been on the short end once in my career of an unsecured debt, uh, when a, when the client or the, uh, um, purchaser of services, but went into bankruptcy and losing a whole bunch of cash, and there’s nothing you can do about it, um, except for.
Be mad and stew over it and learn from your mistakes. Uh, that’s a tough place to be.

Join us February 17th and 18th at Melbourne’s Poolman on the park for Wind energy o and m Australia [00:11:00] 2026, where you’ll connect with the experts solving real problems in maintenance asset management. And OEM relations. Walk away with practical strategies to cut costs and boost uptime that you can use the moment you’re back on site.
Register now at W OM a 2020 six.com. Wind Energy o and m Australia is created by wind professionals for wind professionals because this industry needs solutions, not speeches,
Allen Hall: the problem. With TPI has been keeping the doors open and they went in front of the court and said, we have a liquidity problem.
Uh, Vestus bought those two factories, those two LLCs for $10 million each. That was the agreement During that transaction, TPI asked for another $55 million, uh, and it’s in the transcripts. You can go listen to this dental, listen to it, but obviously the vest representatives were. No [00:12:00] way. We’re not doing that.
We are in good faith. De decided to buy, uh, these two pieces. So 10 million bucks a, a factory is. Pretty decent price, but they are still in a liquidity challenge. So GE Renova and Vestus, uh, don’t want the Blades manufacturing to stop. They have customers who need blades and so they need these TPI factories to keep running.
GE Renova is providing emergency financing. Uh, through what the court calls, uh, Erna, G-E-R-N-A, it’s a liquidity agreement. Uh, they also signed a long lead materials agreement to keep raw materials moving into the plants. Vestas provided cash advances to keep production going at the Mexico facilities also.
So for now, everything continues to be running, but essentially GE and Vestas are pro paying for the materials. To keep the production line going and there’s this, there’s on the back end of this TPI is essentially. Gonna charge, um, [00:13:00] GE vest less for the blades when they roll off the line because they advanced some those funds.
So, TPI as an organization is still trying to continue to produce blades and trying to honor their commitments as much as they can, but they need cash and the, the place they’re going to go get it or have been getting it from as Vestas in GE Renova. So you
Joel Saxum: one would expect that either Vestas or GE Renova would eventually just say like, we’ve got to buy you.
Is that a reality? Because it doesn’t seem like it from the court documents and stuff. It seems like they’re, they’re kind of, they don’t want to get their hands into back or back into, in GEs case, this blade manufacturing, uh, faculties, right? They’re okay right now providing cash for you guys to keep your operation running and providing us with the things we need.
But we don’t actually want to take it over. That’s what it feels
Allen Hall: like. Uh, well, Vestus did, right? So Vestus took over two factories in Mexico. GE has not done [00:14:00] that yet, and there’s no indication from the proceedings that I read on all the documents that GE has made any move to do that. Vestus definitely stepped in and wants to keep the two factories running, uh, with the issues with ge, Renova and LM at the minute, and there was a lot of layoffs at LM just before the new year.
It’s a question of what GE will do, and it doesn’t seem like as of right now, GE is going to buy factories. Now that being said, uh, TPI composites has deadlines to meet and some auctions to run. Uh, the remaining assets, the non vestus. Portion and the, the Turkish operations, which were sold way earlier, uh, all of the remaining assets go up for bid on January 26th.
And if no outside buyer steps in, which is very possible, Oak Tree Capital can use its debt as currency to take ownership of from what is called a credit bid. [00:15:00] From there, uh, the secure lender could convert that debt into equity and, and so basically what happens is Oak Tree Capital. Would be the holder of the company for whatever remains.
But you would think that GE Viva, uh, would want to have some piece of this to keep the blade factories running, but there’s no indication of that. No one from GE has said anything. None of the filings indicate that GE wants to go ahead and or ge. Viva wants to go ahead and buy the factories. Nothing like that has happened.
So there may be, uh, some more financial transactions at play here, but as of right now, everything that remains for TPI composites is gonna be in the auction block. Someone could walk up and for several million dollars, obviously, uh, acquire it and
Joel Saxum: in theory run it. So, I mean, Alan, you and I talked about this this morning a little bit.
We have seen more [00:16:00] layoffs at lm. Right. We saw more people depart and it sounds like that building is basically a ghost town over in Denmark. GE is basically scuttling LM down to nothing, and they will more than likely either sell off whatever LM has or discontinue whatever that business model is, if that’s where they’re going, blade wise, wind wise.
At the same time, they’ve also said, we’re not building any more g offshore turbines.
Allen Hall: What are they
Joel Saxum: doing? I don’t see them having the, the, the, the thirst to go scoop up or put any money into TPI, but it’s like a catch 22. ’cause they need them to fulfill the orders and stuff that they have. Right now what we’re staring at is basically oak tree composites.
Allen Hall: There’s no chance of that. The oak tree doesn’t know how to run that business. They’re gonna have to hire somebody to go do that. Even if they did, you still got factories in Iowa, a bunch in Mexico, other [00:17:00] places. You have all these assets kind of spread all over the place. It’s not like running an automotive dealership on the corner, you’re, you’re running a major operation with thousands of employees and producing these massively complex blades.
There’s only a handful of companies that would be even possible that we could acquire that and run it with any competency at all right now.
Joel Saxum: So does oak tree being, being that oak tree is the debtor in possession and if, if possible with, or if possible, if it, if it rolls this way with the plan toggle, right.
Where they would basically, the cell would convert them into equity holdings and they would own it. Are they the gatekeepers to who can bid? Like do they control ge? You can bid vest as you can bid? Or does the court control that?
Allen Hall: The court controls all of that. So it’s all part of the chapter 11 proceedings.
Anybody can walk up and put a bid in. And now whether it qualifies or not is, is a good question, but anybody can walk up and, [00:18:00] and make a claim for what remains. There’s, there is a process that will happen there, but who else would it be? Nordex? I don’t think so. Is is Vesta gonna buy more? I don’t think so.
So the concern is obviously for TPI, what is it gonna look like going forward? If you have purchased Vestus turbines or GE Renova turbines, are you gonna have the blades that you have purchased in time? Great questions to ask. I think on the other side is if you do own GE Renova or Vestus turbines and they’re made by TPI, where the technical aspects lie, what do you do where, what should you be thinking about if you’re a large operator of some of these turbines?
How I should be planning for the future here? What are you thinking about?
Joel Saxum: So let’s divide it into two categories. One of them is turbine blades on order supply chain, supply [00:19:00] chain, and the other one’s being turbine blades already in production or received order.
Yolanda Padron: I’m not sure that we can fully look at them separately though, right?
Because if you have them, if, if they’re yours and they’re under a service agreement or something. Eventually you might be in the queue for a replacement that you need, right? That your OEM would be on the hook for.
Joel Saxum: That raises another question there then does. I don’t, ’cause I don’t know this. Maybe you do.
Alan does a bankruptcy qualify as a force majeure event?
Allen Hall: Not in terms of like lightning would be, but, but in terms, yeah, sure.
Joel Saxum: Yeah. But can they claim force majeure and be like, uh, out of our control? So now the turbine supply agreements are, you know, basically have to be rewritten. Timelines have to be rewritten.
Yolanda, to your point, if we have a blade that we need for production, am I not responsible for LDS anymore because the blade manufacturer went into, uh, bankruptcy?
Yolanda Padron: I think it’d be more of [00:20:00] either Now you’re not just. In the queue for TPI Blades. But you’re in the queue for whatever we can retrofit there, right?
That they could put in.
Joel Saxum: Yeah. The alternative is you need a whole set though, right? So if we say like, I need a blade from TPI, or I need an entire set of LM blades, now you’re triple the cost. Who has to pay for that?
Yolanda Padron: I really would hope that it, they wouldn’t go this route, but I think some OEMs would just hit liquidated damages.
And stop.
Allen Hall: That’s what I think too. I mean, we’ve seen that happen with some of the OEMs. Is that the, uh, LDS and that’s it. There is nothing going forward. They’re, they’re fine doing that. That’s the only play that they have. I, I am deeply concerned what GE Renova is about to do in the wind business because of their gas turbine and everything else are so profitable.
And they just announced that the wind business in 2026 is not likely to make any. Positive cash flow. [00:21:00] It, the, the discussion inside of GE Renova, at least at the sort of the boardroom level, must be really tense because in, in theory, they could buy TPIs assets in the factories and run them, but they just went through essentially a liquidation process with lm.
Do they want to run another company, especially when they’re bleeding cash in that particular business? I think the answer GE historically has been no. If we’re not number one or number two, we’re getting the heck outta that business. That was the Jack Welsh of running ge, and anybody that worked for GE knew that loud and clear because they said it all the time.
Those same people that grew up in that GE culture are now in the boardroom, and what are they likely to do? They’re likely to follow that advice. Because it’s just what they know. It’s, it’s, it’s, it’s the school they went to. Are they gonna change their mind and say, A longer term play is wind [00:22:00] and we wanna stay in it and we’re willing to lose a couple hundred million dollars a year for the next couple of years, and now we’re gonna run a Blade Factory with several thousand employees down in Mexico.
I just don’t see it. Uh, not that I could be totally wrong about that. Probably am. Uh, today, sitting at the beginning of January of 2026, I don’t think GE Renova wants to be in the blade manufacturing business if they can at all avoid it.
Yolanda Padron: I think it’s important for owners to start thinking a lot more about educating their internal teams on what they can.
So if it’s through, if you know people within your OEM that you can trust and that can help you. Learn how to self-service some of your blades. That would be great if it’s through ISPs that you can trust. If it’s a hodgepodge of items. I think it’s really important for owners right now to start building that up because it will take a while.
I. And, and the risk [00:23:00] is there.

Trump’s Destruction of Renewable Energy Benefits His Support Base, and That’s All that Matters
The death sentence that Trump has imposed on renewable energy in America is good for two groups: a) Big Oil and b) the MAGA crowd that rejects science and wants nothing more than to own the libs, aka “libtards.”
The unforeseen problem for the common American is that solar and wind are by far the least expensive sources of energy, so that the ratepayers in the U.S. are soon going to be shucking out huge amounts of extra cash each month.
Of course, this doesn’t account for the increases in the effects of climate change that, though they are devastating our planet, won’t be affecting the folks in Oklahoma too badly for the next few years while Trump does his best to profit by turning our Earth into a wasteland.

[00:00:00] The Uptime Wind Energy Podcast brought to you by Strike Tape protecting thousands of wind turbines from lightning damage worldwide. Visit strike tape.com and now your hosts. Welcome to the Uptime Winner Energy podcast. I’m your host, Alan Hall. I’m here with Yolanda Pone, Rosemary Barnes, and the Blade Whisperer, Morton Hamburg.
And we’re all in Melbourne at the Pullman on the park. We just finished up Woma 2026. Massive event. Over 200 people, two days, and a ton of knowledge. Rosemary, what did you think? Yeah, I mean it was a, a really good event. It was really nice ’cause we had event organization, um, taken care of by an external company this time.
So that saved us some headaches, I think. Um. But yeah, it was, it was really good. It was different than last year, and I think next year will be different again because yeah, we don’t need to talk about the same topics every single year. But, um, yeah, I got really great [00:01:00] feedback. So that’s shows we’re doing something right?
Yeah, a lot of the, the sessions were based upon feedback from Australian industry and, uh, so we did AI rotating bits, the, the drive train blades. Uh, we had a. Master class on lightning to start off. Uh, a number of discussions about BOP and electrical, BOP. All those were really good. Mm-hmm. Uh, the, the content was there, the expertise was there.
We had worldwide representation. Morton, you, you talked about blades a good bit and what the Danish and Worldwide experience was. You know, talked about the American experience on Blades. That opened up a lot of discussions because I’m never really sure where Australia is in the, uh, operations side, because a lot of it is full service agreements still.
But it does seem like from last year to this year. There’s more onboarding of the technical expertise internally at the operators. Martin, [00:02:00] you saw, uh, a good bit of it. This is your first time mm-hmm. At this conference. What were your impressions of the, the content and the approach, which is a little bit different than any other conference?
I see an industry that really wants to learn, uh, Australia, they really want to learn how to do this. Uh, and they’re willing to listen to us, uh, whether you live in Australia, in the US or in Europe. You know, they want to lean on our experiences, but they wanna, you know, they want to take it out to their wind farms and they ga then gain their own knowledge with it, which I think is really amicable.
You know, something that, you know, we should actually try and think about how we can copy that in Europe and the US. Because they, they are, they’re listening to us and they’re taking in our input, and then they try and go out. They go out and then they, they try and implement it. Um, so I think really that is something, uh, I’ve learned, you know, and, and really, um, yeah, really impressed by, from this conference.
Yeah. Yolanda, you were on several panels over the, the two days. What were your impressions of the conference and what were your thoughts [00:03:00] on the Australia marketplace? I think the conference itself is very refreshing or I think we all feel that way being on the, on the circuit sometimes going on a lot of different conferences.
It was really sweet to see everybody be very collaborative, as Morton was saying. Um, and it was, it was just really great about everybody. Yes, they were really willing to listen to us, but they were also really willing to share with each other, which is nice. Uh, I did hear about a few trials that we’re doing in other places.
From other people, just kind of, everybody wants to learn from each other and everybody wants to, to make sure they’re in as best a spot as they can. Yeah, and the, the, probably the noisiest part of the conferences were at the coffees and the lunch. Uh, the, the collaboration was really good. A lot of noise in the hallways.
Uh, just people getting together and then talking about problems, talking about solutions, trying to connect up with someone they may have seen [00:04:00]somewhere else in the part of the world that they were here. It’s a different kind of conference. And Rosemary, I know when, uh, you came up to with a suggestion like, Hey.
If there’s not gonna be any sales talks, we’re not gonna sit and watch a 30 minute presentation about what you do. We’re gonna talk about solutions. That did play a a different dynamic because. It allowed people to ingest at their own rate and, and not just sit through another presentation. Yeah. It was made it more engaging, I think.
Yeah, and I mean, anyway, the approach that I take for sales for my company that I think works best is not to do the hard sell. It’s to talk about smart things. Um, and if you are talking about describing a problem or a solution that somebody in the audience has that problem or solution, then they’re gonna seek you out afterwards.
And so. There’s plenty of sales happening in an event like this, but you’re just not like, you know, subjecting people to sales. It’s more presenting them with the information that they need. And then I, I think also the size of the conference really [00:05:00] helps ’cause yeah, about 200 people. Any, everybody is here for the same technical kind.
Content. So it’s like if you just randomly start talking to somebody while you’re waiting for a coffee or whatever, you have gonna have heaps to talk about with them, with ev every single other person there. And so I think that that’s why, yeah, there was so much talking happening and you know, we had social events, um, the first two evenings and so.
Mo like I was surprised actually. So many people stayed. Most people, maybe everybody stayed for those events and so just so much talking and yeah, we did try to have quite long breaks, um, and quite a lot of them and, you know, good enough food and coffee to keep people here. And I think that that’s as important as, you know, just sitting and listening.
Well, that was part of the trouble, some of the conference that you and I have been at, it’s just like six hours of sitting down listening to sort of a droning mm-hmm. Presenter trying to sell you something. Here we were. It was back and forth. A lot more panel talk with experts from around the world and then.[00:06:00]
Break because you just can’t absorb all that without having a little bit of a brain rest, some coffee and just trying to get to the next session. I, I think that made it, uh, a, a, a more of a takeaway than I would say a lot of other conferences are, where there’s spender booze, and. Brochures and samples being handed out and all that.
We didn’t have any of that. No vendor booze, no, uh, upfront sales going on and even into the workshop. So there was specific, uh, topics provided by people that. Provide services mostly, uh, speaking about what they do, but more on a case study, uh, side. And Rosie, you and I sat in on one that was about, uh, birds and bats, birds and bats in Australia.
That one was really good. Yeah, that was great. I learned, I learned a lot. Your mind was blown, but Totally. Yeah. It is crazy how much, how much you have to manage, um, bird and wildlife deaths related to wind farms in Australia. Like compared to, I mean, ’cause you see. Dead birds all the time, right? Cars hit [00:07:00] birds, birds hit buildings, power lines kill birds, and no one cares about those birds.
But if a bird is injured near a wind farm, then you know, everybody has to stop. We have to make sure that you can do a positive id. If you’re not sure, send it away for a DNA analysis. Keep the bird in a freezer for a year and make sure that it’s logged by the, you know, appropriate people. It’s, it’s really a lot.
And I mean, on the one hand, like I’m a real bird lover, so I am, I’m glad that birds are being taken seriously, but on the other hand, I. I think that it is maybe a little bit over the top, like I don’t see extra birds being saved because of that level of, of watching throughout the entire life of the wind farm.
It feels more like something for the pre-study and the first couple of years of operation, and then you can chill after that if everything’s under control. But I, I guess it’s quite a political issue because people do. Do worry about, about beds and bats? Mm-hmm. Yeah, I thought the output of that was more technology, a little or a little more technology.
Not a lot of technology in today’s world [00:08:00] because we could definitely monitor for where birds are and where bats are and, uh, you know. Slow down the turbines or whatever we’re gonna do. Yeah. And they are doing that in, in sites where there is a problem. But, um, yeah, the sites we’re talking about with that monitoring, that’s not sites that have a big, big problem at sites that are just Yeah, a few, a few birds dying every year.
Um, yeah. So it’s interesting. And some of the blade issues in Australia, or a little unique, I thought, uh, the leading edge erosion. Being a big one. Uh, I’ve seen a lot of leading edge erosion over the last couple of weeks from Australia. It is Texas Times two in some cases. And, uh, the discussion that was had about leading edge erosion, we had ETT junker from Stack Raft and, and video form all the way from Sweden, uh, talking to us live, which was really nice actually.
Uh, the, the amount of knowledge that the Global Blade group. Brought to the discussion and just [00:09:00] opening up some eyes about what matters in leading edge erosion. It’s not so much the leading edge erosion in terms of a EP, although there is some a EP loss. It’s more about structural damage and if you let the structure go too far.
And Martin, you’ve seen a lot of this, and I think we had a discussion about this on the podcast of, Hey, pay attention to the structural damage. Yeah, that’s where, that’s where your money is. I mean, if you go, if you get into structural damage, then your repair costs and your downtime will multiply. That is just a known fact.
So it’s really about keeping it, uh, coding related because then you can, you can, you can move really fast. You can get it the blade up to speed and you won’t have the same problems. You won’t have to spend so much time rebuilding the blade. So that’s really what you need to get to. I do think that one of the things that might stand out in Australia that we’re going to learn about.
Is the effect of hail, because we talked a lot about it in Europe, that, you know, what is the effect of, of hail on leading edge erosion? We’ve never really been able to nail it down, but down here I heard from an, [00:10:00] from an operator that they, they, uh, referenced mangoes this year in terms of hail size. It was, it was, it was incredible.
So if you think about that hitting a leading edge, then, uh, well maybe we don’t really need to, we don’t really get to the point where, so coding related, maybe we will be structural from the beginning, but. Then at least it can be less a structural. Um, but that also means that we need to think differently in terms of leading edge, uh, protection and what kinds of solutions that are there.
Maybe some of the traditional ones we have in Europe, maybe they just don’t work, want, they, they won’t work in some part of Australia. Australia is so big, so we can’t just say. Northern Territory is the same as as, uh, uh, um, yeah. Victoria or uh, or Queensland. Or Queensland or West Australia. I think that what we’re probably going to learn is that there will be different solutions fitting different parts of Australia, and that will be one of the key challenges.
Um, yeah. And Blades in Australia sometimes do. Arrive without leading edge protection from the OEMs. [00:11:00] Yeah, I’m sure some of the sites that I’ve been reviewing recently that the, the asset manager swears it’s got leading edge protection and even I saw some blades on the ground and. I don’t, I don’t see any leading edge protection.
I can’t feel any leading edge protection. Like maybe it’s a magical one that’s, you know, invisible and, um, yeah, it doesn’t even feel different, but I suspect that some people are getting blades that should have been protected that aren’t. Um, so why? Yeah, it’s interesting. I think before we, we rule it out.
Then there are some coatings that really look like the original coating. Mm. So we, we, I know that for some of the European base that what they come out of a factory, you can’t really see the difference, but they’re multilayer coating, uh, on the blades. What you can do is that you can check your, uh, your rotor certificate sometimes will be there.
You can check your, uh, your blade sheet, uh, that you get from manufacturer. If you get it. Um, if you get it, then it will, it will be there. But, um, yeah, I, I mean, it can be difficult to say, to see from the outset and there’s no [00:12:00]documentation then. Yeah, I mean. If I can’t see any leading edge erosion protection, and I don’t know if it’s there or not, I don’t think I will go so far and then start installing something on something that is essentially a new blade.
I would probably still put it into operation because most LEP products that can be installed up tower. So I don’t think that that necessarily is, is something we should, shouldn’t still start doing just because we suspect there isn’t the LEP. But one thing that I think is gonna be really good is, um, you know, after the sessions and you know, I’ve been talking a lot.
With my clients about, um, leading edge erosion. People are now aware that it’s coming. I think the most important thing is to plan for it. It’s not right to get to the point where you’ve got half a dozen blades with, you know, just the full leading edge, just fully missing holes through your laminate, and then your rest of your blades have all got laminate damage.
That’s not the time to start thinking about it because one, it’s a lot more expensive for each repair than it would’ve been, but also. No one’s got the budget to, to get through all of that in one season. So I do really [00:13:00] like that, you know, some of the sites that have been operating for five years or so are starting to see pitting.
They can start to plan that into their budget now and have a strategy for how they’re going to approach it. Um, yeah. And hopefully avoid getting over to the point where they’ve missing just the full leading edge of some of their blades. Yeah. But to Morton’s earlier point, I think it’s also important for people to stop the damage once it happens too.
If, if it’s something that. You get a site or for what, whatever reason, half of your site does look like terrible and there’s holes in the blade and stuff. You need to, you need to patch it up in some sort of way and not just wait for the perfect product to come along to, to help you with that. Some of the hot topics this week were the handover.
From, uh, development into production and the lack of documentation during the transfer. Uh, the discussion from Tilt was that you need to make sure it is all there, uh, because once you sign off. You probably can’t go back and get it. And [00:14:00] some of the frustration around that and the, the amount of data flow from the full service provider to the operator seemed to be a, a really hot topic.
And, and, uh, we did a little, uh, surveyed a about that. Just the amount of, um, I don’t know how to describe it. I mean, it was bordering on anger maybe is a way. Describe it. Uh, that they feel that operators feel like they don’t have enough insight to run the turbines and the operations as well as they can, and that they should have more insight into what they have operating and why it is not operat.
A certain way or where did the blades come from? Are there issues with those blades? Just the transparency WA was lacking. And we had Dan Meyer, who is from the States, he’s from Colorado, he was an xge person talking about contracts, uh, the turbine supply agreement and what should be in there, the full service [00:15:00] agreement, what should be in there.
Those are very interesting. I thought a lot of, uh, operators are very attentive to that, just to give themselves an advantage of what you can. Put on paper to help yourself out and what you should think about. And if you have a existing wind farm from a certain OEM and you’re gonna buy another wind farm from ’em, you ought to be taking the lessons learned.
And I, I thought that was a, a very important discussion. The second one was on repairs. And what you see from the field, and I know Yolanda’s been looking at a lot of repairs. Well, all of you have been looking at repairs in Australia. What’s your feeling on sort of the repairs and the quality of repairs and the amount of data that comes along with it?
Are we at a place that we should be, or do we need a little more detail as to what’s happening out there? It’s one of the big challenges with the full service agreements is that, you know, if everything’s running smoothly, then repairs are getting done, but the information isn’t. Usually getting passed on.
And so it’s seems fine and it seems like really good actually. Probably if you’re an [00:16:00] asset manager and everything’s just being repaired without you ever knowing about it, perfect. But then at some point when something does happen, you’ve got no history and especially like even before handover. You need to know all of the repairs that have happened for, you know, for or exchanges for any components because you know, you’re worried about, um, serial defects, for example.
You need every single one. ’cause the threshold is quite high to, you know, ever reach a serial defect. So you wanna know if there were five before there was a handover. Include that in your population. Um, yeah, so that’s probably the biggest problem with repairs is that they’re just not being. Um, the reports aren’t being handed over.
You know, one of the things that Jeremy Hanks from C-I-C-N-D-T, and he’s an NDT expert and has, has seen about everything was saying, is that you really need to understand what’s happening deep inside the blade, particularly for inserts or, uh, at the root, uh, even up in, with some, some Cory interactions happening or splicing that It’s hard to [00:17:00] see that hard to just take a drone inspection and go, okay, I know what’s happening.
You need a little more technology in there at times, especially if you have a serial defect. Why do you have a serial defect? Do you need to be, uh, uh, scanning the, the blade a little more deeply, which hasn’t really happened too much in Australia, and I think there’s some issues I’ve seen where it may come into use.
Yeah, I think it, it, it’ll be coming soon. I know some people are bringing stuff in. I’ve got emails sitting in my inbox I need to chase up, but I’m, I’m really going to, to get more into that. Yeah. And John Zalar brought up a very similar, uh, note during his presentation. Go visit your turbines. Yeah, several people said that.
Um, actually Liz said that too. Love it. And, um, let’s this, yeah, you just gotta go have a look. Oh, Barend, I think said bar said it too. Go on site. Have a look at the lunchroom. If the lunch room’s tidy, then you know, win turbine’s gonna be tidy too. And I don’t know about that ’cause I’ve seen some tidy lunchroom that were associated with some, you know, uh, less well performing assets, but it’s, you know, it’s [00:18:00] a good start.
What are we gonna hope for in 2027? What should we. Be talking about it. What do you think we’ll be talking about a year from now? Well, a few people, quite a few people mentioned to me that they were here, they’re new in the industry, and they heard this was the event to go to. Um, and so I, I was always asking them was it okay?
’cause we pitch it quite technical and I definitely don’t wanna reduce. How technical it is. One thing I thought of was maybe we start with a two to five minute introduction, maybe prerecorded about the, the topic, just to know, like for example, um, we had some sessions on rotating equipment. Um, I’m a Blades person.
I don’t know that much about rotating equipment, so maybe, you know, we just explain this is where the pitch bearings are. They do this and you know, there’s the main bearing and it, you know, it does this and just a few minutes like that to orient people. Think that could be good. Last, uh, this year we did a, a masterclass on lightning, a half day masterclass.
Maybe we change that topic every year. Maybe next year it’s blade design, [00:19:00] certification, manufacturing. Um, and then, you know, the next year, whatever, open to suggestions. I mean, in general, we’re open to suggestions, right? Like people write in and, and tell us what you’d wanna see. Um, absolutely. I think we could focus more on technologies might be an, an area like.
It’s a bit, it’s a bit hard ’cause it gets salesy, but Yeah. I think one thing that could actually be interesting and that, uh, there was one guy came up with an older turbine on the LPS system. Mm. Where he wanted to look for a solution and some of the wind farms are getting older and it’s older technology.
So maybe having some, uh, uh, some sessions on that. Because the older turbines, they are vastly different from what we, what we see in the majority with wind farms today. But the maintenance of those are just as important. And if you do that correctly, they’re much easier to lifetime extent than it will likely be for some of the nuance.
But, you know, let. Knock on wood. Um, but, but I think that’s something that could be really interesting and really relevant for the industry and something [00:20:00] that we don’t talk enough about. Yeah. Yeah, that’s true because I, I’m working on a lot of old wind turbines now, and that has been, um, quite a challenge for me because they’re design and built in a way that’s quite different to when, you know, I was poking, designing and building, uh, wind turbine components.
So that’s a good one. Other people mentioned end of life. Mm-hmm. Not just like end of life, like the life is over, but how do you decide when the life end of life is going to be? ’cause you know, like you have a planned life and then you might like to extend, but then you discover you’ve got a serial issue.
Are you gonna fix it? Or you know, how are you gonna fix it? Those are all very interesting questions that, um, can occur. And then also, yeah, what to do with the. The stuff at the end of the Wind Farm lifetime, we could make a half day around those kinds of sessions. I think recycling could actually be good to, to also touch upon and, and I think, yeah, Australia is more on the front of that because of, of your high focus on, on nature and sustainability.
So looking at, well, what do we do with these blades? Or what do we do with the towers of foundation once, uh, [00:21:00] once we do need to decommission them, you know, what is, what are we going to do in Australia about that? Or what is Australia going to do about that? But, you know, what can we bring to the, to the table that that can help drive that discussion?
I think maybe too, helping people sort of templates for their formats on, on how to successfully shadow, monitor, maybe showing them a bit mute, more of, uh. Like cases and stuff, so to get them going a bit more. ’cause we heard a lot of people too say, oh, we’re, we’re teetering on whether we should self operate or whether we continue our FSA, but we, we we’re kind of, we don’t know what we’re doing.
Yeah. In, in not those words. Right. But just providing a bit more of a guidance too. On that side, we say shadow monitoring and I think we all know what it means. If you’ve seen it done, if you haven’t seen it done before. It seems daunting. Mm-hmm. What do you mean shadow monitoring? You mean you got a crack into the SCADA system?
Does that mean I’ve gotta, uh, put CMS out there? Do I do, do I have to be out [00:22:00] on site all the time? The answer that is no to all of those. But there are some fundamental things you do need to do to get to the shadow monitoring that feels good. And the easy one is if there’s drone inspections happening because your FSA, you find out who’s doing the drone inspections and you pay ’em for a second set of drone inspections, just so you have a validation of it, you can see it.
Those are really inexpensive ways to shadow monitor. Uh, but I, I do think we say a lot of terms like that in Australia because we’ve seen it done elsewhere that. Doesn’t really translate. And I, if I, I’m always kind of looking at Rosemary, like, does it, this make sense? What I’m saying makes sense, Rosemary, because it’s hard to tell because so many operators are in sort of a building mode.
I, I see it as. When I talked to them a few years ago, they’re completely FSA, they had really small staffs. Now the staffs are growing much larger, which makes me feel like they’re gonna transition out an FSA. Do we need to provide a little more, uh, insight into how that is done deeper. [00:23:00] Like, these are the tools you, you will need.
This is the kind of people you need to have on staff. This is how you’re gonna organize it, and this is the re these are the resources that you should go after. Mm. Does that make a little si more sense? Yeah. That might be a good. Uh, idea for getting somebody who’s, you know, working for a company that is shadow monitoring overseas and bring them in and they can talk through what that, what that means exactly.
And that goes back to the discussion we were having earlier today by having operators talk about how they’re running their operations. Mm. And I know the last year we tried to have everybody do that and, and they were standoffish. I get it. Because you don’t want to disclose things that your company doesn’t want out in public.
And year two, it felt like there’s a little more. Openness about that. Yeah, there was a few people were quite open about, um, yeah, talking about challenges and some successes as well. I think we’ll have more successes next year ’cause we’ve got more, more things going on. But yeah, definitely would encourage any operators to think about what’s a you A case study that you could give about?
Yeah, it could just be a problem that’s unsolved and I bet you’ll find people that wanna help you [00:24:00] solve that problem. Or it could be something that you struggled with and then you’re doing a better job and Yeah, I mean the. Some operators think that they’re in competition with each other and some think that they’re not really, and the answer is somewhere, somewhere in the middle.
There are, you know, some at least small amounts of competition. But, you know, I just, I just really think that. We’re fighting against each other, trying to win within the wind industry. Then, you know, in 10, 20 years time, especially in Australia, there won’t be any new wind. It’ll just be wind and solar everywhere and, and the energy transition stalled because everyone knows that’s not gonna get us all the way to, you know, a hundred percent renewables.
So, um, I do think that we need to, first of all, fight for wind energy to improve. The status quo is not good enough to take us through the next 20 years. So we do need to collaborate to get better. And then, yeah, I don’t know, once we’re, once we’re one, wind has won, then we can go back to fighting amongst ourselves, I guess.
Is Australia that [00:25:00] laboratory? Yeah, I think I, I say it all the time. I think Australia is the perfect place because I, I do think we’re a little bit more naturally collaborative. For some reason, I don’t know why, it’s not really like a, a cultural thing, but seems to be the case in Australian wind. Um, and also our, our problems are harder than, uh, than what’s being faced elsewhere.
I mean, America has some specific problems right now that are, you know, worse, but in general, operating environment is very harsh Here. We’re so spread out. Everything is so expensive. Cranes are so expensive. Repairs are so expensive. Spares spare. Yeah, spares are crazy expensive. You know, I look every now and then and do reports for people about, you know, what, what’s the average cost for and times for repairs and you know, you get an American values and it’s like, okay, well at a minimum times by five Australia and you know, so.
It, there’s a lot more bang for buck. And the other thing is we just do not have enough, um, enough people, enough. Uh, we’ve got some really smart people. We need a lot more [00:26:00] people that are as smart as that. And you can’t just get that immediately. Like there has been a lot of good transfer over from related industries.
A lot of people that spoke so that, you know, they used to work for thermal power plants and, um, railway, a guy that spoke to a guy had come in from railway. Um. That’s, that’s really good. But it will take some years to get them up to speed. And so in the meantime, we just need to use technology as much as we can to be able to, you know, make the people that good people that we do have, you know, make them go a lot further, um, increase what they can do.
’cause yeah, I don’t think there’s a single, um, asset owner where they couldn’t, you know, double the number of asset managers they had and, you know, ev everyone could use twice as many I think. Yeah, I agree. Yeah. I think something that we really focused on this year is kind of removing the stones that are in people’s path or like helping at least like to, to say like, don’t trip over there.
Don’t trip over here. And I think part of that, like, like you mentioned, is that. [00:27:00] The, the collaborative manner that everyone seemed to have and just, I think 50% of our time that we were in those rooms was just people asking questions to experts, to anybody they really wanted to. Um, and it, it just, everybody getting the same answers, which is really just a really different way to, to do things, I think.
But more than, I mean, we, we we’re still. We’re still struggling with quality in Australia. That’s still a major issue on, on a lot of the components. So until we have that solved, we don’t really know how much of an influence the other factors they really have because it just overshadows everything. And yes, it will be accelerated by extreme weather conditions, but.
What will, how will it work if, if the components are actually fit, uh, fit for purpose in the sense that we don’t have wrinkles in the laminates, that we don’t have, uh, bond lines that are detaching. Mm-hmm. Maybe some of it is because of, uh, mango size hails hitting the blades. Maybe it’s because of extreme temperatures.
Maybe it’s [00:28:00] because of, uh, uh, yeah. At extreme topography, you know, creating, uh, wind conditions that the blades are not designed for. We don’t really know that. We don’t really know for sure. Uh, we just assume, um, Australia has some problems with, not problems, but some challenges with remoteness. We don’t, with, uh, with getting new, new spares that much is absolutely true.
We can’t do anything about that. We just have to, uh, find a way to, to mitigate that. Mm-hmm. But I think we should really be focused on getting quality, uh, getting the quality in, in order. You know, one thing that’s interesting about that, um, so yeah, Australia should be focused more on quality than anybody else, but in, in, in the industry, yeah.
Uh, entire world should be more focused on quality, but also Australia. Yeah. But Australia, probably more than anyone considering how hard it is to, you know, make up for poor quality here. Um. At the same time, Australia for some reason, loves to be the first one with a new technology, loves to have the biggest [00:29:00] turbine.
Um, and the, the latest thing and the newest thing, and I thought it was interesting. I mean, this was operations and maintenance, um, conference, so not really talking about new designs and manufacturing too much, but at least three or four people said, uh. Uh, I would be using less carbon fiber in blades. I would not be, not be going bigger and bigger and bigger.
If I was buying turbines for a new wind farm, I would have, you know, small glass blades and just more of them. So I think that that was really interesting to hear. So many people say it, and I wasn’t even one of them, even though, you know, I would definitely. Say that. I mean, you know, in terms of business, I guess it’s really good to get a lot of, a lot of big blades, but, um, because they just, people, I don’t think people understand that, that bigger blades just have dramatically more quality problems than the smaller ones.
Um, were really kind of exceeded the sweet spot for the current manufacturing methods and materials. I don’t know if you would agree, but it’s, it’s. Possible, but [00:30:00] it’s, it, you know, it’s not like a blade that’s twice as long, doesn’t have twice as many defects. It probably has a hundred times as many defects.
It’s just, uh, it’s really, really challenging to make those big blades, high quality, and no one is doing it all that well right now. I would, however, I got an interesting hypothetical and they’re. Congrats to her for, for putting out that out. But there was an operator that said to me at the conference, so what would you choose hypothetically?
A 70 meter glass fiber blade or a 50 meter carbon fiber blade, so a blade with carbon fiber reinforcement. And I did have to think quite a while about it because there was, it was she say, longer blades, more problems, but carbon blade. Also a lot of new problems. So, so what is it? So I, I ended up saying, well, glass fiber, I would probably go for a longer glass fiber blade, even though it will have some, some different challenges.
It’s easier to repair. Yeah, that’s true. So we can overcome some of the challenges that are, we can also repair carbon. We have done it in air, air, uh, aeronautics for many, many years. But wind is a different beast because we don’t have, uh, [00:31:00] perfect laboratory conditions to repair in. So that would just be a, a really extreme challenge.
So that’s, that’s why I, I would have gone for carbon if, for glass fiber, if, if I, if I could in that hypothe hypothetical. Also makes more energy, the 70 meter compared to it’s a win-win situation.
Well, it’s great to see all of you. Australia. I thought it was a really good conference. And thanks to all our sponsors, uh, til being the primary sponsor for this conference. Uh, we are starting to ramp up for 2027. Hopefully all of you can attend next year. And, uh, Rosie, it’s good to see you in person. Oh, it’s, uh, it’s, it’s exciting when we are actually on the same continent.
Uh, it doesn’t happen very often. And Morton, it’s great to see you too, Yolanda. I see you every day pretty much. So she’s part of our team, so I, it’s great to see you out. This is actually the first time, me and Rosie, we have seen each other. We’ve, we’ve known each other for years. Yeah. Yeah. The first time we actually, uh, been, been, yeah.
Within, uh, yeah. [00:32:00] Same room. Yep. And same continent. Yeah. Yeah. So that’s been awesome. And also it’s my first time meeting Yolanda in person too. So yeah, that’s our first time. And same. So thanks so much for everybody that attended, uh, woma 2026. We’ll see you at Woma 2027 and uh, check us out next week for the Uptime Wind Energy Podcast.

What Can Stop Climate Change?
I looked through a few of the many thousands of responses to the question above on social media and have concluded:
If you ask uneducated people who know essentially nothing about global warming, you’ll find that nothing can stop it, because it’s been going on since the origin of the planet. Others say that God controls the planet’s temperature.
If you ask climate scientists who work in laboratories around the globe who have been studying this subject for decades, you’ll find that there are two key answers: a) decarbonization of our transportation and energy sectors and b) halting the destruction of our rain forests.
As always, we have a choice to make: ignorance or science.
