Speaker: [00:00:00] The Uptime Wind Energy Podcast, brought to you by StrikeTape. Protecting thousands of wind turbines from lightning damage worldwide. Visit striketape.com. And now, your hosts.

Allen Hall 2025: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall, and I’m here with Matthew Stead, who is back in Australia, but not at home.

He’s up in Queensland. Or actually, not even on– in Queensland, technically. He’s on an island off the coast of Queensland. Where are you at, Matthew?

Matthew Stead: Uh, Moreton Island. It’s, uh, like a resort island off, uh, off of Brisbane, so beautiful outside.

Allen Hall 2025: Well, you need a little bit of resort time because you’ve been to two conferences, and you spent a good bit of time in Austria after that.

So you were at WindEurope in Madrid, and then following that, you went right over to Scotland for Blades Europe. So I wanna hear your thoughts. We’ll start with, uh, WindEurope and what was going on at that conference. It did sound like there was a pretty [00:01:00] good attendance, and some people that I have talked to about it really en-enjoyed being in Madrid.

It’s just

Matthew Stead: a bigger city. Um, first time I’d ever been to Madrid, and, uh, yeah, the show was amazing, actually. I was, I was a bit blown away by, uh, I think the OEMs were back out in force. You know, so like the Vestas, Siemens were, um, really– and Nordexes and so forth were really back out in force, so that was really good to see.

Um, the, some of the larger operators had really, really strong presence as well. So you could see that, you know, Iberdrola, Res, um, those sorts of companies were, um, really, you know, putting a big effort in and meeting their customers and, um, really showing, uh, the world who they were. So that was really, um, you know, really good to see.

There were so many people seriously. Um, the queues for food at lunch were, were, um, one of the major problems. Um, so, um, yeah, it was really a lot of people, so that was really exciting. Um, and I mean, for me, I was [00:02:00]trying to catch up with, with partners and friends and, yeah, it was, it was jam, jam-packed just meeting people in the industry.

Um, probably a few other things. So s- you know, SkySpecs and Aerones had a really strong, um, presence there. So, um, SkySpecs and Aerones were, were doing really well. Um, maybe one of the, um, surprises for me, and I know this has been a topic on a few other previous episodes, was there was a lot of interest in bird and bat detection.

I, I, I think there had to be, like, five companies that were, were– had really big setups, and it was a really, really big topic around cameras and so forth. So, um, that was a, a big topic. And, um, then there, there was a really, really strong, you know, supply chain, you know, from, from vessels to cables to, you know, repairs.

Allen Hall 2025: What was the ratio of offshore companies to onshore companies? I’m always curious.

Matthew Stead: You’re looking through the, the list. Um- I would, I’m only guessing it [00:03:00] was probably about 40% had an offshore focus of some kind. So it was definitely a strong offshore focus. Um, obviously, you know, a lot of onshore, offshore combined companies.

But yeah, definitely the word offshore kept on popping up a lot.

Allen Hall 2025: Because Spain is mostly onshore. Like, um, like 99% onshore, right? I think it’s a couple of small projects going offshore. Does it look like the onshore business is gonna pick up, uh, just in terms of the activity on the floor in Madrid?

Matthew Stead: Uh, yeah.

Um, I, I think, you know, like I said, you know, those big operators like the REZAs and the Iberdrolas and, and the OEMs, I, I think it’s just a given that, um, you know, things are buoyant. Um, well, they appear to be definitely very buoyant. Uh, I think we’ve heard, you know, some of the positive, um, financial news from a few of the OEMs recently.

So yeah, yeah, it seems like o- onshore is, is maturing further, further, further. And so you went straight

Allen Hall 2025: from Madrid, right, to [00:04:00] Edinburgh, Scotland. That was a change in weather, I would assume. Uh, probably about a 20 degree Celsius difference. 25 down to 15, yes. Whoa. Okay. Yeah, that’s a good bit. Uh, but the Edinburgh conference, that’s the first time that Blades Europe has been to Edinburgh.

I, at least I don’t remember them being there before. That tends to be a more technical conference than Wind Europe. Uh, the, the Blades conference is obviously focused on blades, and all the relevant experts in Europe do tend to show up there. What were some of the hot topics at Blades Europe this year?

Matthew Stead: Yeah, I think it was, um, an interesting conference. Um, I, I’d been to Blades USA, so I was able to contrast, um, Blades USA a little bit. I think probably the differences here were, yeah, there was definitely some strong, strong, uh, experts there, like you say. Um, you know, Birgit, um, our friend was, was in attendance and a few of her colleagues from Statkraft.

Um, I think, and or, uh, actually ORE Catapult, the, the [00:05:00] UK research, um, offshore renewable energy research, um, they did some great presentations. I really, um, they really shared some really good insights. So, um, ORE Catapult were talking about life extension and, um, you know, looking at the, the fatigue on blades and, uh, how they’re, how they’re going to perform and life extension.

So some great stuff from ORE Catapult there. Probably another key topic that came up was around, uh, sort of related to life extension, but also recycling. The, there was a really good session on the new IEC standard. Um, um, to, you know, full disclosure, I was actually on the panel. So I, I thought it was a great panel.

But, um, the new IEC standard for blade operations and maintenance, um, is really well a-advanced now in its development. Um, very strong risk focus, you know. So depending on the risk then drives your, your blade O&M program. [00:06:00] Um, so that was a, a great talk as well. Uh, and then maybe finally, um, something close to my heart, um, I think the, the, you know, the maturity of CMS companies.

There actually, there were five blade CMS companies there, which is probably the biggest turnout I’ve seen around blade CMS, um, ever. And so it was good to see that sort of, um, interest and growth, um, and the need for, for blade CMS. Uh, and, um, obviously the last one, lightning. So lightning always an issue.

Lots of discussions around lightning, um, you know, through Greece and a few of the, the, the Balkan go- Balkan states. On the blade recycling front, there’s a

Allen Hall 2025: company in Scotland called ReBlade that is involved in some of the recycling efforts. Did they give a presentation of, of what they’re up to at the moment?

Matthew Stead: Uh, yes, I think they did. Um, they’re talking about setting up a, a site in a, a [00:07:00] couple of sites, and I think Inverness was the, the location where they’re, where they’re setting up a site. The, um, the port is supportive, so they’re working through those, those, those challenges. You know, getting a site, getting transport and access to the blades.

Um, working out when, when the, when the blades will come to them. You know, the storage of blades. Um, the, the end, end uses for those blades. Getting all that supply chain, um, lined up was, you know, yeah, it was, that was quite thorough and quite, um, yeah, inspiring.

Allen Hall 2025: And on the CMS side, what are operators trying to monitor?

‘Cause usually have something in mind that they’re going after.

Matthew Stead: For better or for worse, there’s still some serial, um, failure modes. Um, and so the industry is looking at very particular, you know, challenges that, um, certain make and model have. Um, so root insert failures was definitely one of those, um, one of those topics.

Um, and that was actually one of the, the, the [00:08:00] roundtable discussions at, uh, Blades Europe. Some other, um, monitoring around, you know, lightning and- lightning damage and what’s happening with the LPS. That was also, uh, another big topic for, for monitoring. And then a few other sort of general, more, more general, um, you know, natural frequencies of blades and seeing if the natural frequencies are changing, indicating a change in stiffness, which relates to potential damage.

So yeah, there was– it was quite a mix of the types of, um, CMS that was discussed.

Allen Hall 2025: Has the digital twin finally died? Anybody talk about that?

Matthew Stead: There’s actually a current call-out for a new research project in Europe around digital twins. So, um, yeah, one of the larger, one of the larger operators is, is putting, pulling together a team to talk about digital twins, so-

Allen Hall 2025: I, I think this is one of the more difficult things to do, but just because you’re dealing with a variety of blades and blade factories and unique issues that pop up that are…[00:09:00]

You, you really can’t model until after they happen. And after they happen, everybody knows about them anyway. So what’s the point of the digital twin if you can’t detect things early? It, it, it is a great concept, but hard to implement.

Matthew Stead: Yeah. And why? Why would you do it? I mean, you, you’re only gonna do it if there’s a benefit, and what is the benefit?

So, but I think, uh, actually at Blades Europe, digital twins was not really a topic. And maybe one thing I forgot to say is that the, um, Wind Power Lab did a, a good, um, presentation on carbon blades as well, so.

Allen Hall 2025: The, the carbon blades are, is a very good discussion, just because the trend has been lately to scrap blades and bring new ones on site.

And the carbon can be difficult to repair, or it takes a long time to repair, and you just don’t have the manpower or woman power to go out and fix it. So the, the fastest option is to build a new blade. But it does leave a lot of blade waste, which is where the industry is not going. Uh, recyclable blades, which is [00:10:00] in process at the moment, will make that easier, but you just don’t wanna be recycling blades.

You like to be able to repair them. Composites are repairable. And it’s, it is so odd that they, they wanna continue on that pathway, but we’ll see. We’ll see. You don’t really learn the lesson until you do it.

Matthew Stead: Um, however, you know, the, the presentation on carbon blades was, um, you know, highlighted a lot of the challenges, but also highlighted some of the positives and the, you know, how they do help.

Um, and so there was a lot of support for carbon blades, but there’s a lot of unknowns and, um, and there was a lot of discussion around how do you even test if the LPS is working. Uh, it’s just impossible. So, you know, traditional methods on carbon blades, yeah, it just don’t work. So, um, but there was a lot of support that the carbon does bring benefit.

But yeah, I agree with you. There’s a lot of challenges there.

Allen Hall 2025: That’s one of the things we learned years ago back in the late ’80s, early ’90s when we, at least in, in the [00:11:00] States, started building a number of carbon fiber aircraft. And the repair situation and dealing with repairs in, in remote locations became difficult.

And you’ve learned how much training it took to keep an industry running, and you’re starting from zero for a lot of places that all he had worked on was aluminum. It, it’s a completely different world. You’re, you’re training tens of thousands of technicians around the world. You weren’t planning to go do that, and now you are.

So it just, it adds to the cost.

Matthew Stead: It also ties into the OEM, um, you know, providing, you know, details on how to repair those blades because they’re not, they’re not just a standard item, so-

Allen Hall 2025: No, you, you don’t wanna be grinding into a protrusion if you can avoid it. It- you’re just never gonna get it back into that original form because protrusions are in some part magic.

And taking a grinder to them is not gonna… It’s breaking the magic. All the magic will be leaving that protrusion when you do that. Yeah, very [00:12:00]difficult. Delamination and bond line failures in blades are difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production.

CIC NDT are specialists to detect these critical flaws before they become expensive burdens. Their nondestructive test technology penetrates deep into blade materials to find voids and cracks traditional inspections completely miss. CIC NDT maps every critical defect, delivers actionable reports, and provides support to get your blades back in service.

So visit cicndt.com because catching blade problems early will save you millions.

Well, as we know, the wind industry has long been dominated by a handful of European and American turbine makers, uh, particularly in the, quote-unquote, “West.” Uh, but that landscape may be [00:13:00] shifting. Suzlon, the Indian turbine giant that nearly collapsed under about a $1.5 billion of debt just a few years ago, is back.

The company has unveiled a new turbine platform aimed squarely at Europe, and says it will build its first factory on the continent if it wins enough orders. Vice Chairman Girish Tanti, uh, delivered the announcement at the WindEurope conference in Madrid, where Matthew was Signaling that Suzlon believes its time has come.

And since you were there, Matthew, did you hear any news on the floor, any discussion on the show floor about Suzlon entering Europe?

Matthew Stead: Well, actually, yes. So, um, um, there was actually a good, uh, contingent of Suzlon people at, uh, Blades Europe. So, uh, they attended, uh, Wind Europe and then Blades Europe. Um, and I, you know, I was able to have a bit of discussion with them.

I think, I think, uh, they were quite optimistic about, um, [00:14:00] you know, moving back or moving into, into Europe in terms of manufacturing. Um, however, there was an element of skepticism. Am I allowed to say that? So they, uh, were, they were not completely, um, convinced that it’s gonna happen, but, uh, they were certainly excited by that.

It was definitely a, a clear possibility, but not a given.

Allen Hall 2025: Well, they have a, a new platform called the Blue Sky platform, um, which will have, I think, two turbines here, a 5 megawatt and a 6.3 megawatt, which is squarely aimed at Europe and also the United States, for that matter. And building a factory, though, doesn’t make a lot of sense if the cost driver for a factory in Europe is the European employees, which it tends to be when you hear the discussions about the cost structure, it’s about the employees.

I’m not sure why Suzlon would make blades or nacelles in Europe unless they could avoid tariffs or taxation, because India is a very [00:15:00] cost, uh, driven, uh, manufacturing facilities writing country. So why would you wanna go build another expensive factory, probably in the realm of a couple hundred million pounds, uh, if you’re gonna go do it?

It probably doesn’t make any sense to do that as well as just selling turbines into Europe. It seems like the easier path.

Matthew Stead: Yeah. And then you’ve got all the, like, the quality control challenges and, you know, you get the cultural challenges. So yeah, to be honest, I don’t qu- I don’t quite understand the logic behind that either.

Um, maybe there’s, there’s some things that we don’t know about behind the scenes in terms of tariffs and other, other incentives that we don’t know about.

Allen Hall 2025: Would you see operators taking, uh, a Suzlon presentation and maybe even writing plans for developing with Suzlon turbines in the next couple of years?

Is that a, a feeling that Europeans would, would do that, or is Vestas mainly and Siemens Gamesa so strong in Europe that it doesn’t make any sense unless [00:16:00] you’re in sort of the periphery countries of Europe?

Matthew Stead: I mean, my first exposure to a wind turbine was a Suzlon turbine in Australia, and there are many, many, many Suzlon turbines in Australia.

And they’re all, they’re all still working. They’re all still reliable. So I mean, from a reputation and reliability and, um Yeah, history point of view, I can’t see why not. I mean, you know, uh, the operators will see that, you know, they’ve proven themselves. They’re not new kids on the block. Um, and so why wouldn’t an operator think about it?

Allen Hall 2025: Well,

Matthew Stead: in

Allen Hall 2025: this quarter’s PES Wind magazine, which you can download for free at peswind.com, there is a nice article from Muelhen Wind Services, and that is a growing company. A lot going on there. Our friends at AC883 just joined Muelhen a f- few months ago, and is being part of that conglomerate. And, and we know that obviously building wind farm used to mean [00:17:00]consulting with dozens of contractors, and this is where Mue- Muelhen has really s- stepped into the breach here.

So from blade repair at one company and heavy lift cranes at another company, all that had to be managed separately. You’re calling s- different companies all the time. And watching asset managers and site supervisors do this, uh, it is a thankless job. Well, Muelhen’s trying to change that a little bit, uh, and they’re saying that that model no longer works, and I totally agree with them.

It’s insane. Uh, but so Muelhen has consolidated six specialist firms under its one brand, and covering everything from port pre-assembly to long-term operations and maintenance across Europe, the US and Canada, uh, and Asia-Pacific. Its CEO, Søren Hoffer, uh, puts it plainly, “The next phase of wind will not be won by turbine size alone.

It will be decided by the supply chain’s ability to execute.” Boy, [00:18:00]couldn’t say truer words. Uh, I’ve worked with Muelhen or my company, Weather Guard Lightning Tech, has worked with Muelhen on a couple of projects over the years, and we’ve always had, uh, great service from them, and we have talked to a number of operators that love them, that love using Muelhen.

So it’s not a surprise that they’re trying to grow and expand and make life easier for the operators.

Matthew Stead: Sounds like a brilliant move, really. I mean, you know, pulling all these sort of things together is, is a real challenge, isn’t it? I mean, coordinating all these subcontractors, um, getting to turn up at the right time, and yeah, I mean, it just sounds like a brilliant move, and I think that we need more, more, more efficient service companies to service the growing fleet.

So the more they can get organized, the better.

Allen Hall 2025: Yeah, the scale matters here, and the expertise matters. As we’ve have a couple hundred thousand turbines that are [00:19:00] operating in the, quote-unquote, “West,” it does make sense to have a larger player that has seen most of those turbines and has some experience with them.

It’s always the scary scenario when you’re working with a new company. Have they been on this turbine before? Do they know what they’re doing? Do they know- Lockout tagout. Even simple things like that come to the forefront. And the, the trouble is on some of these smaller companies that are in that business is that, uh, you just don’t get the level of service, you don’t get the level of response, you don’t have the horsepower if something were to, to go wrong on site.

They don’t have the cash to, to bring in a second crane or another crew to get this job done. It, it does become scale at some point. And, uh, for a long time in the wind industry, particularly United States, it, it has been a lot of, quote-unquote, “mom-and-pop operations,” and those are slowly getting acquired by the likes of Muehlhan.

I, I, I think this is inevitable at some point. Uh, from the asset owner’s, uh, desktop watching this go on, [00:20:00] how do you see, you know, a large operator interfacing with Muehlhan? Are they gonna do just one-stop shopping at this point? They’re, they’re not gonna have three or four different companies to work with, that they’re just gonna lock into, uh, Muehlhan?

‘Cause, uh, that’s what I see.

Matthew Stead: Yeah. I, I think, you know, from the, the WOMA Conference in, in Melbourne, we saw a bit of a, bit of a shift towards, um, outsourcing, at least in Australia Pacific region. And I mean, if, if you’re gonna outsource, um, you’re, you’re probably gonna join up with a, a Muehlhan, um, equivalent.

So, you know, that way it just takes some of the risk out of, out of it, so it, it sort of makes sense. Um, the other observation I’ve heard is that, you know, because of the seasonality of blade repairs, it’s really hard to keep hold of, um, blade techs. And so if you’re a global company, you’ve got at least some opportunity of using the ses- seasonality and keeping hold of the good techs and, um, you know, so, you know, you know, summer in, in North, North, uh, America, and then, you know, summer in [00:21:00] Australia.

So it, it, it allows these company, allows these companies to keep hold of their good people.

Allen Hall 2025: Yeah. And that, that’s always been the yearly problem, right? That you have a, a crew of a couple good crews in the summertime, and you come back the next summer and it’s a whole different group of people and yeah, that, that, that’s trouble for the industry.

Well, a- and it’s good. It’s fi- it’s finally good to see this happening, and I know, uh, we’ve talked about it internally here at Weather Guard of who to work with and who to partner with. We like working with companies that have scale, and I think we’re finally there. So it’s really interesting to see this article from Johan in PES Wind.

So if you, if you haven’t read the article, you should go visit peswind.com and take a look. There’s a lot of great content in this quarter’s issue, and y- you don’t wanna miss it. So go to peswind.com today. 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 [00:22:00] 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 miss out. Visit peswind.com today. So when, when the energy prices spike like they’re happening right now, uh, the Iran war being one of the main drivers, and obviously gasoline prices have jumped quite a bit, here’s what happens.

The China’s clean energy sector goes to work, and they’re racing to make connections and make sales. As electricity prices jump up, gas prices jump up, everybody wants to try to find a cheaper way to provide energy to their countries or locales. Uh, China’s there to offer it. So it’s solar panels, batteries, EVs, and even wind turbines are, are looking for homes out of China.

Uh, for European wind professionals, [00:23:00] the most important part comes from Mingyang, right? So they were unable to get a production facility in Scotland, but they haven’t given up yet. They are still searching for a home somewhere in Europe. And as of today, I don’t think they’ve found it. They’re s- I think they’re still looking for some country to host them.

But how long is that gonna go on, Matthew? I, I think with the domination of Vestas and Siemens Gamesa in Europe and Suzlon trying to make an entry, will Mingyang and other Chinese manufacturers eventually find a home?

Matthew Stead: It’s interesting. I think, uh, if you look at the airline industry, you’ve always had premium providers, and you’ve always had low-end providers, and I think there’s always a place for all of them.

And so I re- I reckon they’ll find, I think they’ll find their place in, in the market and just, you know, it might just take a while. But they’ve got the strength, haven’t they? They’ve got the product. They’ve got the strength. So it’s just a matter [00:24:00] of time.

Allen Hall 2025: Yeah. I, I, I d- I do think eventually it will happen.

But Vestas and, and Siemens Gamesa have done a pretty good job of controlling it, and wind Europe, honestly. Wind Europe has not been a proponent of a Chinese manufacturer in Europe, so that generally will help slow down any business plans they would have But at the same time, there’s a lot of opportunities around the world that’s not necessarily in Europe, right?

South America has strong ties with China. They’re– And Chinese companies are, are starting production in China. There’s a lot th- things happening there. You’re gonna see that in Africa and other places. So it doesn’t necessarily have to happen in Europe, which is, I think Europeans and Americans think, “Well, we can’t have China in those locales.”

Fine. But it isn’t like China doesn’t have other opportunities to, to sell turbines or solar panels or batteries. There are plenty places on the planet where

Matthew Stead: people that

Allen Hall 2025: need

Matthew Stead: lower cost energy, and they’re gonna find them. Um, I did attend a, a panel [00:25:00] discussion on Türkiye, um, and the growth, and there was a lot of growth in Türkiye around onshore and offshore.

And so maybe Mingyang, that might be a, a place, um, for them to, to start, you know, on the doorstep of, of Europe. The stepping stone, so to speak. Stepping country.

Allen Hall 2025: Is there risk in that, uh, uh, if, uh, uh, Mingyang decided to put a plant in Türkiye? Is, does that come with some political aspect? Because I, I, I don’t remember.

Türkiye t-tends to play, uh, uh, k- kind of like Switzerland in, in terms of working with different, uh, political systems over time. Yeah.

Matthew Stead: I, I’ve had a bit more to do with a few, a few, um, sort of organizations in Türkiye recently and, um, you know, it’s highly professional, highly, you know, logical, and so I, I can’t see why it’d be a challenge.

So I think, yeah, that stepping stone into Europe might be a, a logical way to go. Well, maybe

Allen Hall 2025: we’ll see that in the next [00:26:00] couple of months. I don’t know. There’s gonna be a lot to happen there. There’s so much money being spent in Europe on renewables, wind, solar, battery, all the above, that there’s plenty of opportunity, and every company that has a product that’s gonna be trying to sell it in Europe right now.

It’s a smart move. Absolutely.

Matthew Stead: I think the other thing that we’ll probably be talking about a little bit more is EV trucks or, you know, electric trucks.

Allen Hall 2025: You think so?

Matthew Stead: I reckon we’ll be talking more and more about electric trucks.

Allen Hall 2025: Does Europe even have a, a le- a real true EV tractor-trailer, large truck?

What do they call… I guess they call it a lorry.

Matthew Stead: I don’t think yet. But that’s why I’m saying I think this is a topic that’s gonna raise itself. Um, I’ve, I’ve seen some numbers recently which says that it’s a bit of a no-brainer to go from diesel to, um, to battery now.

Allen Hall 2025: So is Tesla gonna be the, the winner there just because of their, I don’t even what they call it, the Tesla truck?

Is that what they call that now?

Matthew Stead: Not the Cybertruck, the, the truck truck.

Allen Hall 2025: Electric semi-truck. There you go. [00:27:00] Thank you, producer Claire.

Matthew Stead: I think you’ve gotta watch, you know, you’ve gotta watch BYD and a few of the other, the other, um, other companies.

Allen Hall 2025: Do they have something as large as what, uh, Tesla is offering today?

Because Tesla is offering a true semi or tractor-trailer

Matthew Stead: I, I, I must admit I’m not a, a huge expert on the topic, but I’m sure Rosemary is.

Allen Hall 2025: She drives the big rigs? Is that what she’s doing?

Matthew Stead: But I think we– Yeah, I think, I think it’s an in-interesting thing to watch because, um, certainly fuel prices in Australia are definitely pushing, um, this idea of, um, electric trucks.

Allen Hall 2025: Yeah, diesel prices are really high in the States. I- if they’re high in the States, I can’t even imagine what they are in Europe or Australia. They must be through the roof. So if you have a diesel vehicle, although they run forever and are pretty efficient, the price of fuel is insane right now.

Matthew Stead: And, you know, if you, if you take that a step further into mining, so Twiggy Forest, um, and Fortescue, you know, switching to [00:28:00] electric, uh, trucks and electric mining, yeah, it makes sense.

Allen Hall 2025: Does the math work out on that? Uh, obviously Fortescue is taking, uh, really a pretty significant risk in that they’re developing their own electricity generation sites via wind and solar and battery, the whole thing, and they’re converting some of their larger vehicles to electric. Does that hold a big risk, or is this just a financial no-brainer, particularly when diesel prices are so high?

Matthew Stead: Yeah, I think it’s a financial no-brainer. Uh, and that’s why partly I think we’ll be talking about trucks because, you know, once the finances make sense, um, there’ll be a faster transition. And I think, you know, Fortescue is not a silly company.

Allen Hall 2025: Fortescue is willing to dabble, right? So they’re willing to, to see where the technology is and spend a little bit of money and possibly it works out, right?

I think there’s– you have to take a little bit of risk if you’re in that business because you are spending so much money on fuel. [00:29:00] You can spend a couple million dollars playing in different areas to pick an eventual winner. Obviously, they’re gonna– Well, it’s not obvious at the moment, but it, it seems obvious to us being on the electricity side.

Electricity is gonna be the answer. Renewable energy is gonna be the easy way to do it, the lowest cost way to do it. There you go. Go do it. Well, American Clean Power’s event, uh, which is in Houston this year, will be happening June 1st through the 4th at the convention center downtown in Houston. It’s gonna be warm, everybody, so if you’re traveling from a cooler country like Denmark to Houston, bring something cool to wear.

It will be warm in June. It, it– Houston is just a very warm place, and it’s quite humid, so it’ll, it’ll be a, a unique environment. However, it does sound like there’s gonna be a, a, an– A number of interesting companies and a lot of people that are attending that event this year, and one of them is gonna be Matthew and EOLOGIX-PING with Weather Guard Lightning Tech will [00:30:00] both be down at the event in a booth and seeing everybody and, and, and meeting a whole bunch of, of, uh, new people that are getting into the industry, which is, to me, is always the fun part.

Like, we just meet so many really fun people. Uh, and Matthew, you know, we had a discussion internally about that, like, uh, our, our new, uh, chief commercial officer, Nikki Briggs, has been commenting. We’ve been talking to so many operators around the world, and after every, uh, little meeting briefing that we have, we do a post-briefing, and she goes, “They were so nice.”

And I s- yes, Nikki, the wind industry people are fantastic to work with. Like, they’re all focused on doing something positive, and they’re trying to, to do it the best that they can. And there’s a lot of constraints to it, and they’re making a number of hard decisions. But when we all come together at American Clean Power here in the States, hey, we can kinda commiserate and [00:31:00] talk about what’s happening and catch up.

And I feel like we need a little bit of catch-up time in this industry, particularly here in the United States.

Matthew Stead: Yeah. Yeah. I, I think, um, I, I definitely agree. And I, I found, you know, previously I used to work in the construction industry and work with engineers and, you know, transport, blah, blah, blah, blah, blah.

And actually, I found that the renewable industry, there’s a lot of really open people, really happy to have a discussion, um, not the big egos, so I completely agree. And, um, I’m thinking back, um, I first met people in the wind industry in, you know, around 2012, 2013, and, you know, I still know a number of those people and really appreciate catching up with them.

Um, so actually, Berend van der Pol was probably one of the first, and, uh, Birgit Junker was, um, maybe one of the second, so yeah. And I’m definitely looking forward to ACP.

Allen Hall 2025: If you’re, if you’re down in Houston at American Clean Power, definitely stop by a- and say hi to everybody from [00:32:00]EOLOGIX-PING and Weather Guard Lightning Tech, and hey, learn about all the things that are going on because both companies have new products that’ll, were gonna be announced at the site.

Uh, we’re already getting inundated with requests on the Weather Guard side. It’s insane. We’re telling people, like, “Slow down, slow down, slow down. We’ll, we’ll, we’ll talk to you about it when we get to Houston.” But, uh, expect a very attentive audience this year, which is exciting.

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

Allen Hall 2025: Well, Rosemary, welcome back to the show.

Rosemary Barnes: Thanks, Allen. Great to be here. For, it’s been a while since we did one of these one-on-one episodes, like a, yeah, a proper, proper guest. 

Allen Hall 2025: Well, this is kind of a celebratory episode because your company, Pardalote Consulting, has been awarded, uh, some funding from the Australian Capital Territory’s government for the Energy Innovation Fund.

Rosemary Barnes: It’s a really good program that the ACT government has to try and get energy innovation In the state. It’s not a state actually, it’s technically a territory. Little more than just Canberra, the city. Uh, but there are actually quite a few, like, really interesting energy-related companies here, partly ’cause of the, the fund I think helps, but also just tracing back like, [00:01:00] uh, y- you know, in the 20-teens, Australia had a really conservative government that hated renewable energy, and the ACT government had a commitment at that time to 100%, um, 100% renewable electricity for the, the government.

And that was one of the only programs that was resulting in a lot of, um, you know, clean energy projects being built, and one of the conditions that they put on that, uh, for people that would win PPAs with the ACT was that you had to have your headquarters in Canberra. So we’ve actually got quite a few, quite a few really cool, innovative companies out of here.

Um, like Neoen’s headquarters here. Windlab, uh, yeah, was, was founded here and still has a lot of people here. Pardalote obviously, and you know, a few other companies as well. So despite it being a small city of like, I don’t know, maybe it’s up to 400,000 or something people by now, um, yeah, there is actually quite a lot going on here for energy.

Allen Hall 2025: And the Energy Innovation Fund is funded by the wind and solar operators in the area, and your particular [00:02:00] effort has really global consequences. You’re focusing on two areas involving how wind turbines survive Australia, but more, uh, of relevance is to just really tough conditions which exist not just in Australia but around the world.

What two areas are you going to focus on?

Rosemary Barnes: Yeah. So the two focus areas are leading edge erosion and high temperature fatigue, which we can probably get into the definitions of those in a minute. But basically my, um– what led me to wanna have a project like this was that when I moved back to Australia in 2021, I– and I started working in O&M, uh, I noticed that the wind turbines that I would look at, the blades that I would look at here behaved really differently to the ones that I worked with overseas.

You know, es- especially with leading edge erosion, like often I would be doing a condition assessment of a, you know, a new wind farm. Um, might only have been operating for, you know, two years. That’s a pretty common time for people to get in and do a condition assessment [00:03:00] because their warranty period is about to end and they wanna, you know, make sure that everything is okay.

Um, and I would just notice that often, like 90, 100% of blades would already have bad erosion after just a couple of years, which is super-duper fast. And then there are some tools available to check, um, like what kind of erosion are you likely to experience on your site. Like is it a higher severity erosion site or a, a low severity one?

Um, and you basically, you know, the status quo globally is to just look at the annual rainfall, um, and the tip speed. And if you’ve got, you know, high for both of those, that’s a bad erosion site. And if you’ve got low for both of those, it’s a, a low erosion site. But when I plotted out the wind farms that I knew had really bad erosion problems onto, you know, a chart with those two axes, I just saw a random distribution of dots.

You know? Like, this was not– uh, this had no predictive value for Australian wind farms. And so that led me to believe that, okay, um, you know, things are a bit [00:04:00] different here. Makes sense, you know, most of the knowledge that we have about how wind turbines operate, it’s been developed and validated mostly in Northern Europe.

You know? Like it’s, it’s Denmark and the surrounding countries that had, like, the bulk of the early wind energy. First few decades of knowledge were, you know, were mostly there. Of course, there were some other, um, places that had wind turbines, but, you know, most of the The OEMs have been operating for decades, came from Denmark.

And I know when I lived in Denmark, the rain there is very different to the rain in Australia. So in Denmark, it’s basically always raining, right? Like, it’s just… Like, even if it’s not raining, you’re still gonna get wet when you go outside ’cause it’s just, like, the air has this just amazing ability to just hold onto moisture.

Um, but it’s very, very gentle. But, you know, over an entire year of most days having gentle rain, that adds up to a lot. Whereas in Australia, and especially if you go, like, north to Queensland, it rarely rains. It’s mostly just dry, and when it [00:05:00] does rain, it’s like a tap turns on, and I, I swear you will get bruised from the rain droplets hitting your skin.

You know, they just have so much energy in them. So I think that that i- you know, when you look at just the overall rainfall, you really hide something important about how erosion, um, can progress. Then, um, there’s other places in Australia that have very different characteristics. Again, they don’t have that kind of really intense rain but, you know, some of those sites are also having really bad erosion.

And so it just occurred to me, I did a lot of research, you know, into what’s going on and, you know, the academics are studying erosion a whole lot, and they’ve got, you know, a lot of standardized tests and, you know, products are developed according to these standardized tests. But the standardized tests don’t actually resemble reality, and especially they don’t resemble reality in Australia.

And so my client started asking me, “Okay, you know, the products that we have are, are terrible. We have to replace them every couple of years. It’s, um, causing big problems with also [00:06:00] the amount of energy that you’re losing.” One of the types of, um, leading-edge erosion or leading-edge problems that we have in Australia is that the, the coatings tend to peel off and make these, like, big flakes which will just massively disrupt the airflow, can cause y- you know, at least a few percent AEP loss, and maybe up to five.

And even worse than the AEP loss is the revenue loss because it affects it most at, you know, lower wind speeds. Um, you get a bigger hit than at rated wind speeds. So there’s a variety of problems going on with leading edges in Australia, which mean that I, I basically… My clients would ask, “What product should we put on to prevent having to, you know, constantly replace this?”

‘Cause it costs, like- you know, 30, $40,000 per turbine to replace the protection, not to mention, you know, one or two days of downtime. It’s expensive, and I basically, I didn’t have a good answer for them. What, what product should they put on? I don’t know. No, we, we don’t know. One, we don’t know what the [00:07:00] specific, um, characteristics are that are…

what the specific local environment, local conditions are that are accelerating leading-edge erosion, one. And two, all of the products tend to be tested around this, you know, there’s this protocol that academics have come up with, and they’ve kind of like assumed that this is representative of how things behave in the field, and it’s– I don’t think it’s particularly true anyway, but it’s especially not true in Australia.

There are a few companies that are testing to different standards. Um, definitely applaud them. But without knowing wha- what are the conditions truly like in Australia, uh, it’s really hard to advise, like, what kind of tests should you be demanding from a product you’re considering to be sure that you’re gonna put it on and not gonna be replacing it again in two years.

Allen Hall 2025: Because that’s really the trouble in Australia is when you get offered products They have been tested generally in somewhere in Europe and maybe in the United States, and then when they go to [00:08:00] Australia, it’s really unknown as to how those products will do, which is a huge risk for the Australian wind market as to what to choose, how to choose, is it– what’s real in terms of test data.

So now you’re gonna go out and do what? Are you gonna put sensors out by the wind farms? Are you gonna try to do more of a statistical summary of the actual environment around wind farms using existing data? What’s the approach here?

Rosemary Barnes: It’s all of the above, but the part that is supported by the grant is that we’re gonna have enough money to be able to buy some scientific-grade sensors and put them on, um, a sample of Australian wind farms.

So we’re gonna be looking at a lot more characteristics about the rain than simply is it raining now, you know, how many millimeters per hour. We’re also gonna be investigating, you know, every kind of characteristic of, of that, um, of that rain, um, including, yeah, like the, the energy that’s in it, for example.

A, a bunch of stuff. I won’t get into every single [00:09:00] parameter. Um, and you know, other things as well, like measuring UV, solar radiation, um, particles, because, you know, in Australia we have a lot of dirt roads, which I know is very common in wind farms around the world, but Australian dirt roa- roads are always dry and dusty, like 99% of the time, so that’s one of the things that y- you know, maybe that’s causing a difference.

Um, so basically putting sensors all over a bunch of wind turbines and then monitoring the erosion, um, a combination of some real-time monitoring and also looking at inspection, um, drone inspection images annually. We also have a- an option where we’ll just be using SCADA data and inspection images, so that’s like a lower cost version where we can combine that with the findings from the scientific-grade instrumented turbines to build up a picture of what types of conditions lead to accelerated erosion.[00:10:00]

Allen Hall 2025: So the SCADA data will, will have some information inside of it, you think, that, uh, will correlate to the weather outside?

Rosemary Barnes: It has some Additionally, we can look up, um, you know, just the weather data, like how many millimeters fell during which 15-minute interval throughout the day, what was the temperature.

SCADA will tell us also what the temperature was, um, what the speed of the turbine was, so you can calculate the tip speed, ’cause that’s an important thing. Um, yeah, so it’s, it’s two, it’s two tiers of data collection. The scientific grade sensors, as you can imagine, are, are really expensive and y- you know, the, the grant project has contributed a, a lot of funding, um, but it’s not enough to put those, yeah, put a little mini lab on top of every turbine across Australia, obviously.

So that we’re using s- doing selectively, and then we can increase the number of wind farms that are included in the study by just doing this, um, cheaper version of the SCADA [00:11:00] plus, uh, weather data that’s available.

Allen Hall 2025: So what are some of the risks on the temperature side for all the high-temperature regions of Australia that have wind turbines?

Clearly it’s generally warmer in Australia than it is in, in Scandinavia and Northern Europe. What kind of temperatures are we talking about on the ground?

Rosemary Barnes: Uh, well, temperatures here can get pretty close to 50 degrees. Um, and if you’ve ever been inside a wind turbine blade on a, even a mildly hot day, you’ll know that the temperature inside a wind turbine, and especially inside the blade, is much hotter than what it is, uh, what the ambient temperature is.

So this project is one– I’ve actually been talking about this project for, yeah, like over 10 years now. Ever since I started, I moved to Denmark, started working for a wind turbine manufacturer, I had done– I had just finished doing my PhD on composite materials, structural design, and analysis. So, um, yeah, very, very familiar with, [00:12:00] you know, how composite materials work and, in particular, the effect that temperature has on them.

I mean, like most materials, when composites get warmer, they get softer, and that is really important for a w- a wind turbine blade. You know, if it gets, um, less stiff, then you’re gonna get a lot more strain, and that is going to affect your fatigue behavior. Y- you know, fatigue is just the application of a little bit of, a small amount of strain.

It’s not gonna cause damage, but when you apply it millions, tens of millions of times, like you do in a, o- over a wind turbine’s operate, um, operating lifetime, then that builds up. And, you know, wind turbine blades are a very fatigue-driven design. Um, it’s one of the most important things to consider when you’re designing a wind turbine blade.

And so when I got to Denmark and I learned how materials are qualified and how the qualification is treated in the certification process, I just realized it’s not particularly conservative, and also that some of the assumptions that are made that [00:13:00] wo- again, they worked really well in more moderate climates where wind turbines have had most of their developmental history.

You know, it’s not such a big deal there if you test at room temperature. Your wind turbine blade is spending most of its operating lifetime at room temperature or below. It’s, it’s rarely, you know, above 30 degrees in Denmark and most of Northern Europe and, you know, also a lot of, um, a lot of America, not, not all of it But, um, in Australia it has just extended periods above that temperature and even exceeding the temperature where, you know, wind turbines have an operating limit and after that they will shut down.

But the operating limits are based on ambient temperature. It’s not based on what’s the temperature in the laminate, which is what really matters for blade lifetime. So anyway, I’ve been obsessed, like honestly obsessed about this issue for 10 years. Talked about it with anybody who would listen . But then when I started working in O&M in [00:14:00] Australia and I started seeing some wind farms with an abnormal number of cracks early…

again, early in their lifetime, you know, I think one of the wind farms I was looking at was maybe three years old or four at the time. I think it was three actually, and had a lot of cracks, and I looked at a few years in a row and it was more and more cracks every year and I’m like, “Oof, this really looks like end of life fatigue behavior.”

A- actually it’s not, y- you know, there’s this concept of a bathtub curve where, um, when you’re looking at failures in components, in, in anything, not just in, um, wind turbine blades, but you know, like you’d start– it’s called a bathtub because, you know, when it starts operating, you’ll get quite a lot of failures.

Anything big, any manufacturing defects or anything are gonna cause failures quite fast, and that kind of drops off over time as all of those, uh, get addressed. And then you have, you know, the bulk of your operating life, it’s like pretty low level, pretty, pretty constant for a long time and then as you get towards the end of the [00:15:00] life, you start to see failure rates rise up again.

That’s your fatigue failures, your end of life fatigue failures. And so when I saw the same types of cracks more and more each year, I’m like, “This looks like, you know, the foot end of the bathtub, not the head end.” And, uh, it made me worried and I’ve now seen that across a few wind farms in Australia at, um, hotter places.

There’s a few blade types that are more prone to it than others, but at this point it’s still a suspicion that that’s what’s going on. I mean, a suspicion backed by a lot of, a lot of theory and knowledge of how the certification process works. But this project now we’ve got some funding to actually go put some sensors onto wind turbines, actually learn what the temperatures are in the blades throughout the whole laminate, um, not just the, you know, on the outside surface or not just the ambient temperature, but actually, you know, develop a temperature gradient across the whole, um, the whole laminate in the blade shell.

Um, and [00:16:00] then we’re going to be doing a bunch of modeling basically to look at what is the effect of these different temperatures that blades are really seeing and how much would we expect to… that to decrease a lifetime. And then we should also be able to say, you know, if you have this issue in your wind farm, you might be able to change your operation a little bit and extend your lifetime a lot.

Because this one, it’s real– like, in contrast to leading edge erosion, leading edge erosion is just, it’s, you know, every wind turbine has it to a certain extent, and it, it’s always there, but it’s a relatively minor cost to fix it. You know, like it sounds like a lot, like 30, $40,000 per wind turbine, but, um, you know, compared to if you’ve got to replace every blade across your fleet because they’re all, you know, at the end of their life after five years, you know, that’s obviously shocking.

And, you know, that’s a bad example, but even in a y- you know, like a less extreme example, maybe [00:17:00] after 15 years you have to do a, you know, a f- a fleet-wide campaign to strengthen blades or something. It’s, you know, m- many millions of dollars for that, and so it c- could make sense to be able to learn, okay, what, what hours of operation should we be avoiding?

Additionally, because when it’s super-duper hot in Australia, usually you’ve got heaps of solar power and the electricity price is not that high. So I, I think that there– and I don’t, obviously, before we’ve done the project, I don’t know what the threshold is. But in both cases, we will be aiming to improve the knowledge of how you can operate to avoid these periods of accelerated damage.

Allen Hall 2025: Do you think you’re seeing more fatigue-like damage due to the blades operating when it’s hot or not operating when it’s hot, with maybe less airflow around the blade and maybe less cooling going on is just a temperature soak At rest? [00:18:00]

Rosemary Barnes: Yeah. It’s interesting because the temperature is higher if it’s not rotating, um, because you get a whole lot of, um, convective heat, heat transfer when the turbine is operating.

So your temperatures are not gonna get as hot when operating as when they’re standing still. However, if it’s standing still, they’re only very lightly loaded. Like, yes, they’re gonna get, um, blown by, by gusts and, um, have a little bit of bending, but it’s, it’s very, very small compared to, uh, if it is y- you know, operational loads.

Uh, assuming that you’re not in the middle of a s- a storm. But yeah, a storm probably doesn’t come with 50 degrees temperatures.

Allen Hall 2025: And what part of the blade is susceptible to these higher temperatures? Is it the resin? Is it the fiberglass or carbon fiber? Or is it the, the glue, the bond joints? What part are you focused on?

Rosemary Barnes: The resin is the main part that I’m focused on. It gl- it could be an issue for glue too, actually. I haven’t even looked into what the, um, yeah, temperature assumptions are with, with glue, with [00:19:00] bond lines. But the failures that I’m seeing in the field are not, are not bond line issues. It’s, it’s, um, a laminate problem.

Allen Hall 2025: What about balsa and foam inside of the blade? Are they affected by the temperatures or are they pretty temperature stable?

Rosemary Barnes: I don’t think they’re affected at these kinds of temperatures, no. They, they don’t really do much actually. The, the core materials, like it, it is very important that they’re, that they’re there, but their job is really to keep the fiberglass separated from its- itself to make it stiffer.

So, um, yeah, that’s, that’s unlikely to be a, a major source of problems.

Allen Hall 2025: So this study is gonna work over about three years, and you have a number of wind farms that are participating. Are you looking for more wind farms to participate in Australia?

Rosemary Barnes: Yeah. Yeah, definitely. I mean, we can, um, have as many as, as people want to join.

We’ve got quite a good selection so far. Definitely can always welcome more. A, a bit limited in how many can get the really, um, good sensor [00:20:00]package, because the grant funding is a, you know, a certain amount, and that’s paying the bulk of those sensors. So, um, those spots are limited. So if anybody wants to really zone in on what is specifically causing erosion on their site, you know, if you know that you have got leading edge protection that is not good enough and you have to replace it soon, but you don’t know what to replace it with, then, you know, that would be the kind of wind farm that might want to consider, yeah, joining this and, um, you know, getting these sensors on their, um…

We’re putting them on top of the nacelles, most of them. Um, yeah, so that would be a good match then. Um, and then, yeah, for the ones that are doing the SCADA data and, um, weather data- There’s not such a, a hard limit on how many we can have join like that. So yeah, we can have more, more like that.

Allen Hall 2025: In the temperature fatigue effort, i- is that still looking for participants or are there particular wind turbine types or manufacturers that you’re [00:21:00] looking for to participate?

Rosemary Barnes: Yeah, I think, um, I, I mean yes, we can have more of those. That’s a simpler, a, a simpler issue as well. The sensors are not so expensive and, um, it’s, yeah, it’s a, it’s a simpler project to join that one. We only need, you know, a couple of turbines per site, so it won’t be such a, uh, an involved process to get everything up on into the turbines.

And in terms of who might like to join that, I would say anybody that is in a really hot area where, you know, where they see a lot of days over 30 degrees, and if they see any days, you know, getting into the high 40s, then I would say that that’s worthwhile. Or even I have seen this issue in some milder sites, um, yeah, depending on the, on the blade type as well.

It is more common with polyester resins. They have a, a lower op- uh, maximum operating temperature than epoxy resins. But then also just anybody that has noticed just, hey, [00:22:00] we’ve got a lot of cracks, and it seems like we’re getting more and more cracks every year, which to be honest, can be hard to keep track of if you’re…

If you’ve got a full service agreement, uh, you know, an OEM managing your wind farm The early signs of this are gonna be category one and category two cracks. They’re not in exactly the same location. It’s, you know, it’s a tricky one. Normally, if you’re looking at a serial issue, then you’re going to have, uh, well, you know, your ideal pattern for a serial issue is the exact same thing happening over and over again.

And so it is harder to pull this out. It also really would be very rare for it to be happening in the first two years or three years, whatever your serial defect liability period is. So it’s quite hard. But, um, another group of wind farms that might like to consider it is if you know that in, you know, a certain number of years you have to renegotiate your service agreement or, you know, it ends and you might have to take over yourself, then this’ll be a really good way for you to [00:23:00] understand, you know, have I got a ticking time bomb here?

Um, because it’s not something that you’re gonna be aware of if you haven’t been, you know, doing some really, really in-depth shadow, shadow monitoring of your blades, you know, running your own inspections and looking at every single damage, not just category three, four, five, but lower ones. So yeah, I mean, there’s a, a wide variety of people that, that could be interested in joining.

Allen Hall 2025: Are you expecting a number of manufacturers that make leading-edge protection or involved in resin creation, some– there’s a number of resin companies and a variety of resins that are used globally, sort of interchangeably at times. Are you expecting some of those companies to participate in this effort just to learn about the Australian environment?

Rosemary Barnes: I think it would be a good opportunity to test out some products and see how they behave in the Australian context. I think that that would be a really good selling point, but I, I have to say that most of the companies doing that sort of thing that wanna enter Australia, they don’t [00:24:00] really consider…

Like, from the perspective of wind farm owners in Australia, if you can’t show us wind farms in Australia where this has worked and, you know, show us a before or after, you know, the old LEP lasted Two years and our LEP is going on four years now with no damage. It, you know, unless you’ve got a before and after like that, you can tell us however many turbines that you’ve got installed around the world, but, um, we don’t consider it validated, y- you know?

It’s not validated for Australian conditions yet. And I do have this same discussion over and over again with, you know, not just leading edge protection, but all kinds of, um, you know, manufacturers of whatever doodads that you put on to improve a, a wind turbine. It’s so different to Australia. Things break so fast.

And I’m talking everything, you know, like vortex generators fall off and, um, yeah, like, uh, you know, bits of lightning protection systems fall off, seals just [00:25:00] crumble and disintegrate. Um, and it, you know, we’re very wary of, of new products. So I, I do– I mean, I’m thinking of it more from my client’s point of view than from the product manufacturer’s point of view.

But one thing that I wanna get out of this pro- project is to be able to answer one of the most common questions that I get is, which is, what leading edge protection should I be putting on my turbine? And for now, I don’t know. I, I know a range of products that don’t work in Australia, and not much more than that.

So, um, yeah. And it’s also, you know, Australia’s a very varied place with lots of different kinds of climate too. So it’s not gonna be like, you know, the product that works in Queensland is the same one that’s gonna work in Tasmania, which is the same one that’s gonna work in Western Australia. You know, um, so it, this project is gonna really pull out what are the site specific issues you’ve got at your site and what kinds of, um, you know, tests would we need to see a product um, perform in order to know that this [00:26:00] is gonna last on your site.

Allen Hall 2025: W- what is the outcome of this project or these two projects? Are they gonna be reports or, uh, a, a continual monitoring system that’s designed for the Australian environment? How do you see this going?

Rosemary Barnes: Yeah, so one part of it is, um, developing a way to identify periods of accelerated damage and to know not to operate during that time.

So we call it protective operation. Uh, so that would, uh, help you if, yeah, you’re trying to extend the life of something or increase the amount of time before you have to repair, then y- you know, that would be useful to have that knowledge. And it will be as simple as just an alert saying, “Hey, accelerated damage conditions.

Consider, you know, if you wanna keep on operating.” And, you know, if the price of electricity is super high at that time, they may want to push through, and if it’s low, they probably won’t want to. So that’s one thing. Um, especially, you know, as wind turbines get to their, near the end of their life. I’ve got some clients whose wind farms only have, you know, [00:27:00] maybe five years operation left.

They just simply don’t wanna repair their leading edge protection again. They just, they, they don’t wanna do that. So they would be happy to, you know, reduce operation a bit and have their turbine limp through to the end of the period. Y- you know, you want everything to wear out at once. You don’t want brand-new leading edge protection on a turbine that’s going to come down in a couple of years.

Um, so, you know, that’s, that’s one part of it. And then the other thing is, you know, turbines earlier in their lifetime, how can we optimize the maintenance schedule with leading edge erosion? Um, so, you know, like it’s a lot cheaper to, uh, replace the LEP if you get– catch it early, but then you don’t wanna be catching it too early and replacing it, you know, constantly when you, you don’t need to.

So, um, yeah, it, this, having this knowledge will enable a site-by-site operations and maintenance strategy with respect to leading edge protection. We also have some sites who are having trouble. They’ve got a full service agreement, and the OEM is [00:28:00] responsible for, um, doing the leading edge erosion repairs and protection replacement, but the owner is on the hook for paying for it.

At the other end, we’ve got people with full service agreements where technically the, um, manufacturer is supposed to be doing the leading edge protection and paying for it, but they argue about what, when does it need to be done. Because, you know, um, the operator might think if there’s no structural risk, then we don’t need to be replacing it.

And in the meantime, you’ve got turbines spinning around for years and years and years with, you know, these huge flakes of leading edge protection s- you know, causing the flow at the tip of the turbine to, to detach and to stall, and horrible aerodynamics, huge losses in power generation and revenue. And they’re having a big fight about, you know, is this necessary to do or not?

And then, you know, they’re just gonna put the exact same product on again ’cause the [00:29:00] OEMs are re- all really, really wedded to their own particular brand. It’s like, “Well, last time we had this product and it was factory applied, it lasted one year before it s- it was worse than, you know, if it wasn’t there at all.

Uh, we don’t really want you to put that one on again.” And so, you know, having the information that they need to be able to, you know, really bring data to these discussions and, you know, makes a, yeah, data not drama. That’s a, a good approach I think, um, for any kind of negotiation and especially in the case of leading edge erosion.

And then for the high temperature fatigue part of the problem, aside from, you know, just wanting to know are your blades aging, should you be looking at remediation action or changing the operation, the other really big key thing is, uh, you might need to have a fight with y- your OEM about if this turbine has been designed and operated correctly.

And so then having the data from this, um, project is going to give you the information that you need to come into that [00:30:00] argument with, again, the data not the drama. Um, and to, you know, in- increase your chances of succeeding in that kind of really tricky negotiation.

Allen Hall 2025: So if you’re an OEM or a manufacturer of equipment, an ISP, an operator, pretty much all aspects of wind operations, you probably ought to be getting a hold of Pardalote Consulting and Rosemary to talk about the opportunity to participate in this study.

How do people get ahold of you to, to do that?

Rosemary Barnes: People can go to our website, pardaloteconsulting.com, and get in touch via the contact form there, or you can, uh, look me up on LinkedIn, Rosemary Barnes. That’s probably the easiest, fastest way to get ahold of me personally.

Allen Hall 2025: Well, Rosemary, congratulations on the Energy Innovation Fund Awards and the new three-year effort.

If you are interested in participating with Pardalote Consulting and working with Rosemary and her team [00:31:00] in Australia, reach out to her on LinkedIn and get that process started, because this report and the data from all this analysis that’ll happen over the next couple of years will be important to the wind industry.

So you need to spend some time and get ahold of Rosemary and get this process started now. So Rosemary, congratulations. Uh, thanks for being back on the podcast, and looking forward to, uh, the next couple of years. It sh- should be exciting.

Rosemary Barnes: Thanks so much, Allen.

Artificial Stupidity?

We all understand that there are ultra-conservatives living all around us, but does anyone truly believe that our schoolteachers are ruining our society by teaching children the truth about U.S. and world history? Science? Current events?

Slavery and Jim Crow laws were bad.  Fascism is bad.  Our scientists are telling us that CO2 emissions are causing world temperatures to rise, destroying our planet’s capacity to support life.

Whom do these concepts upset?

No Such Thing as a “Dumb Question”

There is nothing dumb about the question posed at left.  Democracies fail, falling into “banana republics” constantly.  The rate at which democracies become tyrannies is so great that some of them never make the news. Can you tell me anything about the governments of Eritrea or Chad?

What makes the situation in the United States is, yes, that it’s happening here in the United States, the very last place anyone would have suspected it.

You might have thought that Americans wouldn’t have voted for their nation to become Russia or North Korea.

You would have been wrong.
