Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host, Alan Hall in the Queen city of Charlotte, North Carolina.

Rosemary Barnes in Australia and Joel Saxon in the great state of Texas. Just before we hopped online to record this podcast, Rosemary was telling us about a number of turbine problems on LinkedIn and. Rosemary wanted to comment on them. These are some of the larger turbines. Rosemary are newer turbines.

Uh, some of them onshore, some of ’em offshore

Rosemary Barnes: for the, yeah, for the most part. Um, yeah, both onshore and offshore. Some a little bit older, but the common thread is, um, [00:01:00] just like spectacular fail failures of multiple blades of one across multiple turbines of one, the one I saw most recently. Had blades smashed to pieces.

It had towers that had just like fallen apart. Like it was, um, like they weren’t bolted together. Like it was just blocks stacked on top of each other and they had, you know, just an angry baby had just topped them over. That’s what it looked like. And um, I think what’s really interesting is reading the comments in those and it just, without fail every single time, the first few comments are gonna be.

Um, justifying how that is just cool and normal, like either by the company itself or the turbine manufacturer itself saying, oh, you know, oh, this was just a prototype. So, you know, it doesn’t matter that it fell apart, like. Forgetting about the fact that, okay, it’s just a prototype, but it’s still an operational turbine that people would’ve been inside it to install it.

They’re inside it to maintain it. You know, people are inside those things. They’re not supposed to be able to just fall apart by the time that it gets to that point.

Joel Saxum: I, I, I think I’ve seen some of these same posts, Rosemary, and one of the ones that I saw recently [00:02:00] was not even, it wasn’t new, it wasn’t prototypes.

It was, it was like, there’s a picture, there’s three turbines with, or four turbines and there of the, of the dozen blades in the picture, nine of them are gone. It’s just a nelle hub with like little stubs on three turbines, and those are only like 850 kilowatt, one megawatt, 1.5 megawatt machines. They’re, they’re old.

Rosemary Barnes: Yeah. Yeah. And so I think a typhoon went through in that particular case and I made a comment, you know, like it’s either poor turbine design or it’s really poor site assessment. In either case, it’s a failure, right? Like you don’t put wind turbines that can’t withstand a typhoon in a place that gets typhoons.

Um, but you always, you always say people saying how this is actually great engineering. And I just thought this is just the classic example of that, um, that was written under this latest post, and I’ll just read it out. The pictures point to the designers of these turbines. Having done that, designing to a certain wind speed, having done that to a high degree of consistency, I note three failure types [00:03:00] in the pictures, blade snap, tower, buckling and bolt failure, pointing to all parts, having been designed to the same survival.

Wind speed looks like they did their job well. And it’s just like, oh, what, you look at this, at this path of like it’s Godzilla has run through this wind farm, and you’re like, oh yeah, that looks like a job done. Well, well done guys. It’s just like, if we can’t learn anything as an industry from these kinds of things, then, you know, how can we expect to have a, a bright future for the industry?

Like it? It’s one thing to fail, but if you look at a failure and say, that’s actually a success that is. Just the worst possible outcome we have. We have to be able to say what went wrong, what do we do to make sure this doesn’t happen again? You have to. You have to learn, otherwise you’re going backwards.

Allen Hall: Are you worried about unexpected blade root failures and the high cost of repairs? Meet eco Pitch by Onyx Insight. The standard in blade root monitoring. Onyx state-of-the-art sensor tracks blade root movement in real [00:04:00] time, delivering continuous data to keep your wind farm running smoothly and efficiently.

With Eco Pitch, you can catch problems early, saving hundreds of thousands of dollars. Field tested on over 3000 blades. It’s proven reliability at your fingertips. Choose eco Pitch for peace of mind. Contact Onyx Insight today. To schedule your demo of Eco Pitch and Experience the future of Blade Monitoring, there’s been a series of leadership transitions that is really changing the face of the wind industry.

Onyx Insight. The Macquarie Capital Back Condition monitoring specialist who’ve had in the podcast, um, has appointed Alexis Grennan as this new chief executive officer Alexis Bringss dearly 20 years of experience from Joel. Schneider Electric where he most recently served as CEO of the digital grid division, and his expertise in smart grid software solutions and energy management systems positioned him to lead [00:05:00] Onyx Insights expansion beyond its current 28,000 wind turbines under monitoring across 35 countries.

So obviously Onyx is a big provider of CMS systems. They are the sole provider of CMS systems on GE turbines at the minute. Onyx is making a lot of moves. They just acquired 11 I recently also. So they’re, uh, what it looks like right now. They wanna be the, the leader in CMS.

Joel Saxum: Yeah, I think it’s, if you go deeper into their history a bit.

You know, the couple of CMS solutions around gearbox was really where they started then. Then they got to the eco pitch thing, and then now the blevin. And I think if you’re sitting in that boardroom, you’re thinking they want to be the center hub for IO ot, IOT being sensors out in the field. Anything that comes in, they want to be able to amalgamate it and help people out in that direction.

Um, you know, a new, a new CEO that has, uh, 20 years at Schneider [00:06:00]with digital grid. That’s awesome. Right? Good hire there. I would think. Um, I, I do see this as a trend in wind. You’re seeing some more CEOs and senior leadership coming into organizations from outside of wind directly. Some of the bigger capital holders, you know, the Goldmans of the world and the Macquarie’s and that kind of things, if they have portfolio companies, you’re seeing people be placed in leadership roles that are coming from outside of wind and bringing expertise from, of course, usually energy, software, supply chain, these kind of things that we need, but some fresh blood at the leadership level.

I like to see that.

Allen Hall: Well, the addition of the grid coming into Onyx, is that an expansion plan? Because there is a lot of work going on expanding the grid and monitoring the grid and making the grid carry more energy than what it was originally designed for. And I’ve listened to a number of podcasts over the last month that talks specifically to it.

It, it is a definite growth area. [00:07:00] You think this could indicate a move into other areas besides just the basic wind? CMS. Solutions.

Joel Saxum: Well, let’s think about it this way. So in wind, when you have wind specific companies, you’re starting to see intenders or you have been seen intenders for the last few years, even just the most basics inspections.

Okay? We’re inspecting blades. Use your RFP. Now those blades say, and blades plus BOP. So we want you to do the transmission lines. And then you’re seeing some of ’em that are BOP plus substations. So all the sub, all the way back to the edge of the wind farm where connects to the grid. Um, so companies are adjusting, like you’ve seen Skys specs adjust to that.

You, you know, whether it’s partnerships or expanding things internally and other companies as well, even down to the ISPs starting to do more and more and more because they’re being asked to. This makes sense because, uh, at the end of the day, if you’re working for a subset of customers, there’s only so much budget in.

Of turbine work and if you wanna expand your company and grow, you need to expand in other [00:08:00] areas. So why not just keep it going down the line of connection to the grid, inter, inter wind farm issues, those kind of things out of the wind farm. So I, I don’t know if that’s ON’S plan, but I can see that. I think that from a strategic standpoint, it makes sense.

Allen Hall: Well, as Schneider is involved in all kinds of aspects of the grid worldwide, so I would assume bringing in a new CEO would open up maybe some horizons to Onyx and maybe there’s adjacent businesses that they should be in because they have a lot of technology and they’re pretty smart group. They may want to expand outwin just a tiny bit just to, to test the waters, see what they could do there.

Well, going to solar seems like an obvious choice, but there could be other areas that they may want to look at, at least in the short term to see if they can add value.

Joel Saxum: Yeah. Grid infrastructure. Right. I think that that’s a, we talk about it regularly that our, our entire global grid is aging quickly. It’s aging fast, and with the changes coming [00:09:00] on board with.

You know, different generation types, all the batter, different types of battery storage, and you know, like our, our conversations with Joe Chicon over at Podge about, uh, frequencies on the grid and all these different changes and load changing and AI data centers coming up and on and off and on. Um, it’s really highlighting the need for a future digital grid, uh, and upgrades to it.

So Onyx is probably, you know, in the wind world that we see, they’re probably sitting pretty. In a pretty good spot as compared to most companies to be able to engage in that and bringing on someone from the digital grid side of Schneider. Smart move in my my opinion, I dunno. Rosie, what are your, what are your thoughts on that

Rosemary Barnes: in general?

I think it’s really good to move people around to similar industries or a little bit different, different roles. Uh, I think that that’s a, um, a real way to drive innovation forward by bringing in different perspectives. I know that I. I found myself appearing more innovative when I lived in Denmark. You know, just purely [00:10:00] because I had seen and experienced and done things in a different, a different way, solved similar problems in a different way.

Um, just, just through what I, you know, the kinds of engineers I worked with earlier in my career. It was different to the way that a lot of Danish people had been taught to approach problems. And it just, you know, when you bring in a few slightly different people, it really expands the um. Amount of options that you have on the table for solving new problems as they come up.

And all of these kinds of industries are doing stuff that hasn’t been done before, right? So I think you do want to have as many different options that you, as you can come up with to, um, end up with the good solutions and you’ll get more options if you don’t choose people that are all from the exact same background.

So I think in general, that, um, it’s always good to, to shake things up

Allen Hall: in this quarter’s PES Win magazine, there’s a lot of great articles that you. Need to read. And the way to do that is go to PS wind.com and download your free edition. [00:11:00] And we wanna talk about an article in the magazine this quarter, Joel, which is Hybrid Breaks Ya Breaks.

Why you would use ’em, why they’re, this is a little bit different than what we typically see on like a GE machine. Uh, Siemens GAA uses these quite a bit, which are sort of a passive and an active, so they’re a break. So there’s a hydraulic cylinders and there’s some active pads that close, but there’s also some static pads and they’re using slip rings instead of a, a bearing surface to rotate the jaw.

So if, if that makes sense. You to do an active system, uh, you can really put stress on your, on your ball bearings and probably flatten them over time if you keep squeezing enough. With this system, it’s a little more control, a little more precise. So you’re, I, I think the, the argument they’re making is that it, uh, simplifies the system, so there’s some complexities to it, but overall.

It costs less, [00:12:00] and that’s what we should be doing in engineering, right? Trying to figure out ways that maybe just cost a bit more for a component, but less overall.

Joel Saxum: Is it a direct retrofit? Like is this a, Hey, we’ve, we’ve had, we’ve had a component fail, so we want to put a new system in. Or is it like aix, swap it out now as a CapEx cost?

Or is it like during Repower, when are they putting this on?

Allen Hall: It’s from Donor Wind Solutions, uh, and they’re doing, doing it as part of OEM work, right? It, it does take a little bit of finite element analysis because of the way it loads up the, the yaw system. So you want to make sure that it doesn’t overload it if you’re gonna use it, but it’s one of those things in wind like, uh.

Try to choose a simpler system on a smaller turbine. As you get larger and larger, your approach probably changes. And this is what Ner is pointing out.

Joel Saxum: I’ve noticed that actually, if you’re, if you’ve frequented any wind conferences, technology shows, exhibitions, you will know where NER is because everything on their booth is lime green.[00:13:00]

Um, I love that. I think it’s a great approach, uh, which everybody knows. It’s, it’s like seeing the Dema, the Dema ships or the SVA ships in a port. You’re like, you know what? That one is right away. Uh, but del nor, but that’s what Nert does, right? They, they are. They have parts that are direct replacements.

Great. This is the part we’ve made it a little bit better, but it’s a direct replacement. But they also are re-engineering things, making them better, uh, for the long haul, uh, from a operations standpoint. ’cause I’ve seen some of their pitch, they have different kind of pitch systems and stuff as well that they are, are retrofits for, for, uh, specific machines that have trouble with them.

Um, but yeah, uh, this one to me, I’m not an expert on jaw brakes. Of course, that’s not my thing. Uh, but I do know that whenever you have to deal with that YA system, whether it be the gearing, the brakes, or the, you know, like the, the pucks and the GE go bad all the time. Like it’s an undertaking, uh, down to the point where people have developed UPT tower machining processes to fix, uh, issues with the YA system and whatnot.

So, um, if they’re, if, if someone is putting this [00:14:00] much engineering effort into fixing a problem, it’s definitely a problem.

Allen Hall: Yeah. Even think about the problem though, you have so much weight. Up into the cell and you’re trying to pivot all the time, and the wind is trying to move into the cell whether you want it to or not.

The YA system kind of takes all the abuse. So designing a system to last is really the key here. Without breaking things, I mean how many turbines have we seen where the YA gear teeth have been damaged or broken off? Because the brake system is not really de-stressing those teeth. It matters a lot. So as we get more and more efficient with wind turbines, we gonna be thinking about all the different components that go into a wind turbine and making them more efficient, making ’em last longer, making them cost less.

So if you haven’t downloaded the latest PES wind. Magazine do it. You can read this article from Donor. Just visit PS wind.com. As Wind Energy Professionals, staying informed is crucial, and let’s face it difficult. That’s why the Uptime [00:15:00] podcast recommends PES Wind Magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future.

Whether you’re an industry veteran or new. Wind, PES Wind has the high quality content you need. Don’t miss out. Visit PES wind.com today. Well in the US when a wind company wants to put some turbines on your farm, uh, the operator just talks to the, each farmer individually and negotiates a deal. Now a lot of those deals are very similar, but you may find from neighbor to neighbors, slight differences and farmers are getting.

Smarter over time. Clearly. Uh, a professor or assistant professor up at Purdue University in Purdue is in Indiana, kind of central part of the United States, explains that landowners can be paid up to $10,000 per acre annually [00:16:00]to lease to wind energy companies. And that’s a great amount of money. We’ll take that, but, and the turbines only occupy maybe one to three acres, and so you can continue to farm your several hundred acre parcel.

Uh, but. This professor notes that the farmers are starting to consider other factors than just the money, including the visual impact community relationships, which is the big one I think lately. And political beliefs about renewable energy, which jolt talks about all the time in Wisconsin. Uh. The advice from the professor is have an attorney to review the lease and to make sure that the wind operator is going to restore the land to its original condition once they stop using the turbines.

And I think that makes a ton of sense. So you’re seeing a slight shift in the way that landowners are coming to agreement with some of the operators. It is about the money, a large part of it, but they’re also trying to navigate the neighborhood situation where they don’t make their neighbors upset. You can imagine a lot of them have been there for generations and they don’t [00:17:00] want to really make the neighbors mad at ’em.

Uh, so you’re seeing a lot different types of leases coming about now than maybe you saw five years ago even. And that has evolved, uh, quite a bit. But the money is still good. I think most people, at least in the United States, most farmers will. Like to have that additional revenue. It just makes the farm much more profitable over time.

But that same situation doesn’t exist worldwide. And Rosie, are you seeing something different in Australia? It does seem like there’s a little more spreading of the wealth in, in terms of revenue.

Rosemary Barnes: I actually listened to a good podcast episode on this recently. Uh, it was the switched on, not the Bloomberg switched on, but the renew economy switched on.

Um, and they interviewed a now retired farmer who had, had one of the very early wind farms, um, in Australia, put on his farm. And I mean, his story was o overall very positive. It it, the [00:18:00] time when they started talking about it was during a very severe and prolonged drought in Australia and he had actually been trying to sell off land, um, just to keep the.

You know, keep the lights on, um, and was unable to sell. Like just there’s no buyers at any price at that time. And then, so the wind farm came and he, he also mentioned how important it’s to get, um, lawyers, good lawyers advising on the contract because he mentioned that he was getting paid every year before construction as well.

And that it ended up taking 10 or 14 years, I can’t remember the exact amount of time, but a long time. Between starting to talk about it and actually having the wind farm built. And if he hadn’t have had that, he said he wouldn’t have been able to make it. So, um, that was one thing. But yeah, so and so overall it was very positive for him.

He was eventually able to sell his farm and, and retire, um, nicely with a profitable farm. He also mentioned that he was able to do a lot of upgrades on the farm with the money, the revenue that was coming from the wind turbines. So when we went to sell, it had all new fences and, you know, stuff like that [00:19:00] that made it very attractive and easy to sell.

Um, but he also mentioned a few things that were just really bad, and he sounded really angry in that episode, um, where, uh, he, he said at that time it was like the wind developer knew everything and the farmers knew nothing, and they tried to keep it that way. Like he had a brother on a neighboring property was also in discussions about wind turbines, and they were forbidden from talking to each other.

I think that that’s a lesson that’s been learned over the last 10, 20 years in Australia, is that. It’s really worth it to put a bit of effort upfront in, um, listening to what people’s concerns are and then doing something about it. Uh, I think there’s been so much emphasis on like listening and talking and listening.

That’s not the important part. The important part is then understanding what the issues are and then, um, you know, removing those, those barriers. And, you know, money is a big part of that.

Joel Saxum: I spent. A eight plus years dealing with these issues in the field with landowners on, on oil and gas [00:20:00] projects, right?

So there’s stages of oil and gas projects from exploration to production and all these different things, and they, and everybody gets different lease payments and, and access payments along the way. And, and if you, you know, if someone has locked up your land in the seventies, you may only be getting five bucks.

And if someone has this, they’re getting more. It’s, and it, what ended up happening is, is. You need to, you need to, and we’re in the, we’re in the same space of wind because those same people, those same professionals, landmen and permit agents and stuff that worked in oil and gas work in wind and solar as well.

It’s the same companies. It’s the same ideas.

Allen Hall: Yeah. Same groups.

Joel Saxum: Yeah, same groups. Um, they, they need to distinguish and make sure they’re taking care of participating landowners and non-participating landowners. And the non-participating landowners, just like we’re talking about here, they’re just as important as the participating ones because they’re the ones you’re gonna piss off.

Uh, so, so you’re starting to see some payments going directly to them as well. Like if you’re within X amount of feet of a turbine, even if you’re not on your land, you are starting to get a little bit of a payment [00:21:00] in some areas, in some spots. Um, but one thing I wanna flag is, at the beginning of this, we talked about a lawyer, bringing a lawyer in and having them look at certain things.

I would say this and maybe the wind industry developers are gonna hate me for this. But there’s a legal, legal concentration called, um, a, a favored Nations clause or a most favored Nations clause. If you are a part of anything of this sort, make sure any, any signing, any contract for wind, uh, non-participating.

Participating. Make sure you have a clause like this in your contract because it will basically State wind Farm goes in a hundred turbines. If they’re offering you five bucks an acre and they’re offering your neighbor a thousand, you get a thousand too. It makes, it makes everybody equal in the playing field.

It doesn’t give anybody, uh, you know, better terms and conditions. Once one person gets a term and condition, that’s good, everybody gets it. That has that most favored nations clause in their contract. So have a lawyer institute that if you’re gonna be a part of one of these.

Allen Hall: Yeah. The other thing that was pointed out in the [00:22:00] article was, uh, a lack of increasing payments adjusted to inflation.

So some of the farmers are pushing back because inflation is relatively high. So if you got $10,000. Per acre per year in 2035, he may want to see something more like $15,000 per acre per year because of inflation. That to me makes a lot of sense, but I know a lot of leases don’t work like that. They’re just.

Fixed price. It’s today’s price and it stays that way until the end of the lease. It’s just simpler to do. There’s a lot less math to do. But Joel, as you see more, uh, farmers getting advice, taking advice, do you see this evolving into a more of a standard contract where they. Do have the favored nation.

They do have inflationary increases based on cost of living or some federal standard so that you’re, instead of having to negotiate every contract completely separate, you’re getting [00:23:00] something a little more universal, including helping the neighbors.

Joel Saxum: Yeah. The tough thing there is that a lot of wind.

Okay, so we’re like, I’m just gonna pick the United States example. You’re in different states, you’re in different counties, you’re in different areas, right? So if you go to Minnesota and you talk to someone in Minnesota about their mineral rights, they more than likely don’t know what you’re talking about.

Yeah, because that’s not a thing up there for most of Minnesota. Some of Minnesota is right, the Iron Range and whatnot, but if you talk to someone in Texas about mineral rights, that’s just as important or of more important than their actual real property surface rights. So they know and, and they have to build contracts around certain things the same way oil and gas contracts were like at oil and gas contracts at, you know, early days were easy.

It was X amount per acre. That’s it. Uh, now you have people buying strata and leasing strata out of, uh, subsurface things, and you have. Payments tied to payments tied to production, right? And I haven’t seen a whole lot of wind payments tied to production. I don’t know if that exists or solar, um, [00:24:00]that that can be a, you know, a shared upside or shared downside type thing.

Um, if someone’s gonna pay me $15,000 an acre, I’m just taking the cash. I don’t care what your production is ’cause that’s a great rate. So, so, um, you, you know, I think that. Using these organizations that have been doing this for a long time, that is a smart way to go if you’re an operator, uh, that know how to navigate the town halls and that know how to do these things professionally because there is actually just like you have to have a real estate license.

There is a professional landman license, uh, of, to do this kind of stuff. Uh, so there’s schooling, there’s certifications, all this. Again, I’m just talking in the United States here. Um, but, uh, I don’t know if I see a across the board. Federal type contract. ’cause it’s just too many municipalities, too much, too much going on.

Allen Hall: Well, we’ve been looking at a lot of wind farms the last couple of months on the lightning side and realizing, you know, how [00:25:00] dedicated the wind farm installations are to putting ’em on ridge lines, even if it’s a, a. A hundred feet higher. So that tends to spread out the wind farms. Unlike in some parts of Kansas where there isn’t a lot of variation in the, uh, in the surface in other places.

We’re just looking at Oklahoma, uh, where the turbines are specifically falling ridge lines. So you’re gonna end up crossing a lot of property lines when you do that, I assume. And you and I have been on a number of sites where. We’re going from one turbine to another and we’re crossing three or four different property owners and not that far of a distance.

Fences and gates. Right? The fences and gates. Bet. So even if you don’t have a turbine on your property, you may have a road on your property. And the how they navigate that. So if, if, if, if whoever’s. Taking on those contracts and negotiating on those contracts has a load of work to do. It’s going to be,

Joel Saxum: and like I like, I think I go back a little bit like it’s gonna be dependent on where you are, because a contract in Kansas is gonna look a lot different than a contract in Wyoming versus a contract in Texas just simply [00:26:00] because of local laws, access rights, these kind of things.

I’d say, I mean, however, one of the, that’s one of the things that’s cool to touch on is some of these farmers and ranchers, like when I was in oil and gas stations in Wyoming, they loved when the exploration crews came ’cause they would get money for roads. And they’d be like, oh, these old two tracks. Make that into a road that can take an 18 wheeler down then, then you can have access.

And they’re happy, happier than hell. This week’s Wind Farm of the Week is the Alta Complex owned by TerraGen out in California. So at one point in time, of course if you’re a part of wind lore in the United States. You know that this was the biggest wind farm in the United States at 1,550 megawatts. It was also the third largest onshore project worldwide.

Now there’s been a couple of the Sun Zia projects and stuff have been a bit bigger, but this thing is massive. Uh, spreads across about 9,000 acres and holds, hosts almost 600 turbine. Uh, so it started in 2010. Multiple phases of construction, uh, ended in 2014 and financed with almost $3 billion. [00:27:00]Uh, and it’s in that Tehachapi Pass area.

So, uh, it has, it actually still does have some capacity for expansion. Uh, but we wanted to share this one because, uh, just the size and scale of this thing, uh, being that it’s so big, uh, and as well. Long-term power purchase agreement signed with Southern California Edison. Uh, the output averages enough power to, to power about 450,000 homes annually, uh, which is just massive.

Uh, it’s created over 3000 jobs. And I think this one, the economic story might be the, the, the, the feather in the cap, uh, is it in his injects over $1 billion into the regional economy, which is just massive. So, uh, kudos to the wind industry for making this one happen. Uh, but looking ahead, uh, it is a bigger part of that Tehachapi wind resource area when it has the expan or has expansion potential of up to 10 gigawatts.

Uh, as California continues to grow out, its renewable grid. So this week’s wind farm, the Ulta Wind [00:28:00] Complex, so owned by TerraGen out there in California, the Wind Farm of the week.

Allen Hall: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Rosemary Barnes, Yolanda Padron, and Matthew Stead. Fraunhofer has published peer-reviewed feasibility research in wind energy science. And Rosemary, I don’t know if you read wind energy science, but there’s a lot of good information there about wind turbines and mechanical aspects.

Not much on the electrical side, but a lot about mechanical. Uh, in, in, in wind energy science, uh, they had a discussion or an article about repairing damaged pultruded CFRP spar cap planks while the blade stays on the turbine. Using finite element analysis on a 81.6-meter [00:01:00] blade from a seven-megawatt offshore turbine, the researchers found that a shear web window cut out as short as one meter drops buckling resistance from 20.7 times critical load to four times critical load, a reduction of over 80%.

The fix? Temporary external clamping frames with a pre-tensioned span-wise rod to carry gravity loads, combined with internal push rod assemblies and external stringers profiles to restore buckling resistance, all installed and removed uptower. Wow. I know we’ve discussed the carbon pultrusion repair situation and how critical that is or h- how difficult it is.

I didn’t realize it was that difficult, Rosemary, that if you actually try to replace a one-meter section of a carbon pultrusion, you’re re- reducing the, the, what, the, the buckling resistance by 80%? [00:02:00] Holy moly.

Rosemary Barnes: I don’t think that’s even 100% pultrusion specific, right? They’re talking about cutting a, a window in the shear web.

Allen Hall: Yes.

Rosemary Barnes: So that could be for any kind of repair you might have to do that, including if you need to repair, like sometimes you need to repair the, the shear web. Um, and even though, like, they’re not doing a lot of heavy lifting, um, that’s kind of a structural pun, um, they’re still super important. If they’re not there, then you’re gonna have big problems pretty immediately.

The way that it works with repairs is that there’s certain kinds of damage that you know that you can just do uptower. The technicians know they can do it. They don’t need to call an engineer. The engineer doesn’t call- need to call the expert engineer. But when you need to do something a bit unusual, like a whole meter of web removed, then you’re gonna need to get an engineer to, um, dial in the, y- the, to rerun the design codes basically, um, but with this weak structure now to see is this okay and is it okay, you know, uh, [00:03:00] obviously a turbine that is just, um, idle or it’s not even idle, it’s just fixed in place while they’re repairing it, that has different loads on it to one that’s operating.

So, you know, they’ll run that and make sure that it’s safe, um, before they do the repair. So what I really like about Fraunhofer is that they in some ways, like- Maybe it’s not cutting-edge science or engineering because they are largely repeating what is already well known in industry. But the problem is that industry doesn’t tell everybody else.

And so it is, like, such a vital role to then go and illustrate, um, to everybody else what, what’s happening in industry. And they, they are… Like, there is this problem with wind energy where academia and industry are not, um, talking too much, and a lot of the academic stuff just doesn’t relate at all to what’s happening in the industry.

But Fraunhofer do, like, 90, 90% of the time seem to get it at pretty right.

Allen Hall: When a carbon protrusion is [00:04:00] used, that really localizes where the load is versus in, in some of the more fiberglass designs that I’ve seen, the shell is actually taking some of the load. It’s not all in the shear web, so to speak. So doesn’t that sort of focus the loads into one location a little bit more when you move to carbon?

Isn’t that the point?

Rosemary Barnes: Yeah. Well, the carbon fiber is, is a lot, lot, lot stiffer than, um, fiberglass, and it’s, it’s a lot stronger. So yeah, you are designing… I, I mean, always the spar caps have been the main load carriers, the, um, you know, the main laminate, the bit between the shear webs or over the shear webs.

Um, but it’s, yeah, it probably is, um uh, e- exacerbated or the increased effect when you add carbon fiber. But the, the thing about carbon fiber is it’s so susceptible to small damages or small deviations, so like a tiny little bit of fiber waviness, like if your fibers aren’t perfectly straight, then you can easily get a, a crack.

And [00:05:00] carbon fiber can also be a lot less forgiving than fiberglass. It is not uncommon that it will just break, and you didn’t even know there was anything wrong. So that damage intolerance is what led to people moving away from carbon fiber fabric and into pultrusions, because they’re made with perfectly straight fibers.

Um, but it, it raises some, uh, problems of its own because y- yeah, like how do you repair that? You can’t, um, you can’t get the fibers as straight again unless you repair a whole plank, um, because like they look like, like two-by-fours or something. You know, like they look like little fence palings, basically.

Black, black fence palings. Um, and so yeah, you, you’d have to repair, replace a whole one, and then you’ve got like a big chunk of structure that’s missing there, so that’s pretty hard to do uptower. I, I don’t know anybody that does those uptower, actually. Um, m- maybe they can now with this reinforcement method, but I would still not enjoy being in a blade that was missing a, a [00:06:00] pultrusion and up in the air.

Allen Hall: The offshore versus onshore equation, it, it would make more sense onshore to actually drop the blade, I assume. Offshore adds difficulty, but it sounds like with all the rigging a- and assembly that you would have to do offshore, it, it probably is gonna be close in terms of total cost to do an uptower repair versus a downtower repair I would think.

It, it– Wouldn’t you think it’d be roughly right?

Rosemary Barnes: Yeah, like in, in offshore, there’s always more motivation to do complicated, um, expe-expensive uh, things that will save you from having to do something even more expensive, like bringing, um, a whole blade back. Uh, yeah, going out, getting the vessel with the crane, bringing the blade down, and taking it in is just incredibly expensive.

So you can spend a lot of time faffing around reinforcing a blade uptower before you, um, you know, would come out behind. But you know what? While we’re on topic of carbon pultrusions, I think it, like it, um, it’s almost bypassing the, the biggest risk with them ’cause [00:07:00] what I see is the– Like it’s one thing when you know you’ve got damage that you need to repair, but far more common, I think, is that you don’t even know that you’ve got damage.

It’s very hard to, to see what’s going on in there. Um, I mean, people aren’t just going up periodically and doing ultrasounds, ul-ultrasound scans of their entire blade. But even if they were, it’s still not that easy to find all of the, the little damages in, in pultrusions. So, um, yeah, that’s something…

‘Cause it’s not such an old technology. It’s been around for, I, I don’t know, like not even 10 years these have been, being used consistently, probably more like five, um, that there’s been a lot of them out there. And I just, yeah, I, uh, maybe I’m overreacting because all I see is broken blades in my career, but, um, you know, I am a little bit worried that we’re gonna start to see as, you know, fatigue builds up, that we might start to see some more like sudden breakages in these blades.

Allen Hall: If Fraunhofer’s working on it, there must be a reason for the [00:08:00] analysis and all the engineering time that they spent on it, that it’s a concern. I don’t know how you would do it offshore, honestly, because of all the wind loads. That you would have this damaged blade, and yes, you would have all the engineering calculations, but I would just see the safety people being very concerned about it.

Because if it does go free, you have a couple of people up there minimum, and who knows what’s below.

Rosemary Barnes: But even the amount of time in between knowing that you have to, um, replace a pultrusion and actually getting up there to do it, like I’d be surprised that it didn’t break in that, in that time because it is such a big, a big, a big thing.

Um, so yeah. Uh, but super interesting work and I do, I, I do really, really appreciate that the Fraunhofer exists to, you know, do this sort of stuff and, um, give us the information w-we need to get a better understanding.

Allen Hall: Delamination and bondline failures in blades are [00:09:00]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

UK government has deployed 15 million pounds, uh, which is about $20 million, uh, through Innovate UK in a coordinated push to move offshore wind technology from prototype stage into commercial supply chains. The package has three components: a 10 million [00:10:00] pound offshore wind innovation program, open competition for high potential businesses, a five million pound wind innovation hub to align industry, government, and research, and a 12 million pound effort for phase one of a large structures innovation center on the Isle of Wight, with Vestas already signed as its first industry partner for sustainable blade development.

So the, the large structure innovation center is a composite center which is gonna be doing some advanced technology work on blade design. And I think there’s no better place to do that at the moment than in the UK. But it does open the door to a number of UK firms, and even outside the UK firms, to get involved in the UK offshore and somewhat on the onshore side.

This has massive potential, I think, within the UK and outside the UK, Matthew.

Matthew Stead: I, I know from my own firsthand experience that, um, uh, actually getting into the wind space is, like, really [00:11:00] hard. So for this sort of, um, incubator and support around, um, you know, setting up businesses, I, I think this is a really, really good thing for the UK government to be doing.

Um, ’cause, yeah, how do, how do you build up a future industry if you, if you don’t have the new businesses coming through? So I, I think it’s a, it’s a, it’s a great thing that the UK government’s doing. And yeah, and how do you get small companies working with the larger OEMs? How do you get the innovation?

Yeah, it’s, yeah, I think that’s probably, you know, got five gold stars for the UK government.

Allen Hall: What are the areas that they should be focused on over the next couple of years? Obviously, blades is, is a massive one. I’m sure Vestas is gonna be deeply involved with that. Are there some other areas in technologies that the UK should be orienting its supply chains towards?

Matthew Stead: I’m personally 100% biased towards blades ’cause w- we know that, you know, um, if we look at the failures and we look at the failure rate, you know, where is the greatest growth in failure rates? It’s blades. Um, [00:12:00]you know, why, why are we still having failures? Why haven’t we learned? You know, where is the knowledge exchange?

Um, so I- I’m biased, but I think it’s, it’s, it’s, it’s needed in, in the blade space. Yeah, as what, you know, Rosie and you were talking about before, um, you know, knowing more about, um, what’s going on, how it can be repaired, how it can be dealt with, I think is super, super critical.

Allen Hall: Well, Vineyard Wind has its 62 turbines in the water south of Martha’s Vineyard, but the project is delivering only partial power while GE Vernova works through its outstanding repairs.

Now, the financial pressure is breaking into public view on two fronts. Boston landlord BP Hancock LLC is suing Vineyard Offshore, uh, the Avangrid and BP joint venture, for nearly $1.2 million in back rent at its John Hancock Tower offices. Uh, separately, GE Vernova wants out of its turbine supply contract, claiming Vineyard Wind owes [00:13:00] it over $300 million.

Vineyard Wind fires back that it is actually owed more than 800 million from GE Vernova, so that, that saga will continue for a while. But it is a little odd that the rent is not being paid by Vineyard Wind at, at, in the John Hancock Tower. And if you’re familiar… That’s downtown Boston. If you’re familiar with downtown Boston, that, the John Hancock Tower is one of those iconic buildings you see in pretty much every downtown photo of Boston.

There must be a lot happening at the moment at Vineyard that they’re not able to pay the rent, or they’re trying to shuffle some money around or, or seek more financing. Sounds like they’re in a refinancing phase, honestly. Yeah,

Yolanda Padron: I know that at, at times there’s– it’s really common for, for an asset manager to think, you know, “Oh, we have X amount of money,” and then all of a sudden you– it’s all of the, the additional [00:14:00] repairs or the additional operational costs stack up to a bit more than they thought they were gonna have, and then maybe they don’t even have enough money to go do trash removal or anything.

And that happens, and it’s more often than, than we’d like to admit. Um, but this is on a bigger scale, right? Like, this is a project that we’ve talked a lot about, everyone’s talked a lot about, and it has a lot of eyes on it. And so for it to, to be so behind on rent on such an iconic place and such an important place and such an important part of the country, backed by a very important company, it’s really, it’s really interesting to, to think about kind of what they’re thinking.

‘Cause in, in my mind, right, like, if I was the people backing them, I would think, “Okay, well, the f- first thing’s first, like, let’s not give them any additional reason to hate us right now.” Right? Or like, you know, the public opinion is really big on these kind of things. Um, so I, I don’t, I don’t know what the, what [00:15:00] the exact plan is here.

Allen Hall: Well, I wonder if this is part of the, the negotiation with GE Vernova, that, uh, the, the payments and the, the power which leads to payments, uh, hasn’t been at it- its desired output from Vineyard Wind and is this an effort to, uh, shore up their legal case with GE Vernova to say, “Hey, look, uh, Avangrid’s not gonna throw a bunch of money in, even for rent.

This project needs to stand on its own two feet, and it can, but GE Vernova needs to be involved with it and get the turbines up and running to the level at which they were contracted to do”? Is this part of that play? ‘Cause it just feels like it. You know Avon Grid has the money to pay the rent. That’s not even a question.

It’s, but it’s why they are not doing it is probably the bigger question at the moment. Is, is it just all legal maneuvering at the minute?

Matthew Stead: I, I wonder if it’s a bit like, uh, you get the utility billing, you get the [00:16:00] electricity billing, you put it in the, the drawer over there, and then you forget about it, and then you forget to pay it, and-

Allen Hall: It’s a million dollars

Matthew Stead: $1 million out of, uh, 600 or whatever billions, you know? Maybe it was, maybe it was just a simple oversight.

Allen Hall: It could totally be oversight, but it’s, it seems like with the amount of attention that Vineyard Wind and GE Vernova are, are getting, and they are literally within a stone’s throw of one another, they can s- I’m– You could probably see the GE Vernova building from the John Hancock Tower, that, uh, you, you think that some of this would get settled, but it’s not.

It’s still going on. It’s, it’s crazy. It– With, and with Avon Grid and BP still being involved with it somewhat, uh, there’s something happening behind the scenes that has not poked its head up yet. It’s coming, though. This is all coming to a head pretty quickly. The– Massachusetts needs Vineyard Wind to run.

They really do, and it’s, it is a little surprising at [00:17:00] times that the state of Massachusetts is standing on the sidelines in this.

Matthew Stead: As wind energy professionals, staying informed is crucial, and let’s face it, difficult. That’s why the

Allen Hall: Uptime Podcast recommends PES Wind Magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future.

Whether you’re an industry veteran or new to wind, PES Wind has the high-quality content you need. Don’t miss out. Visit peswind.com today. In this quarter’s PES Wind, there’s a lot of good articles in there. If you don’t have a copy, you can go to peswind.com and download one. A interesting article from Safe Lifting, which is a European-based lifting company that does basically bespoke engineering on lifts, and they’ve been making a push that’s saying that the next wave of projects depends on bigger [00:18:00] turbines, of course, which means bigger lifts, but they need to have some standardization to them.

Uh, things like spreader beams and rigging systems that are pre-built and pre-validated, uh, just reduce the overall engineering time it takes to do these lifts. Uh, and rental equipment models are a lot lower cost than buying OEM-specific or site-specific lift equipment, trying to keep the capital costs down.

That’s one of the big pushes in the wind industry is lowering the overall cost of installation. It does make sense, but it– as we were talking off-air a minute ago, a lot of lifts for basically the same kind of turbine are different. The, the connection points are different. There’s a lot of engineering that goes on there, and as the turbine sizes reach 15 megawatts plus, and the cells are massive, blades are massive.[00:19:00]

But it does seem like in a lot of other aspects of wind, there is some standardization, an IEC spec or some sort of overall guidance document for the industry that like, let’s put the lift points here, here, here, and here and lift with the right equipment. And Matthew, we just haven’t done it in lifting, even in smaller turbines, same thing.

Matthew Stead: Oh, it’s crazy. Um, I was, I was thinking about it, and, you know, my, my suggestion would be that, you know, when I buy 100 turbines, I should get, um, a blade lifting kit. It’s like when you buy a car, you, you get a, you get a kit to change the tire, don’t you? So I would’ve thought it would be just fundamental. Um, but, but, but we know that the wind industry is not always logical.

Um, so what is, what might be considered normal in a car is not normal for a wind turbine. Um, but yeah, uh, you know, this sounds like a perfect way of going to have more of a sort of standardized and, you know, not, not wait for the OEMs, but actually lead this and, and [00:20:00] drive this standardization. So yeah, thumbs up from me.

Yolanda Padron: I think this is really cool. Uh, I really hope that if we can standardize the way that we do that, we can make sure that the teams are trained in, like, the standard ways of, of lifting. I know that, um, I’ve, I’ve seen a few cases where someone didn’t know, there hadn’t- been exposed to a particular blade type and they were in char- you know, in charge of, of lifting it to, to, to do a blade replacement and then, um, they accidentally ended up damaging the blade and so you had this bad crack that they kind of painted over because it was a little bit embarrassing for them at the time.

And then, you know, a year later it’s like, well, okay, well, maybe next time ask someone, um, if you if you don’t know the, the exact lifting protocols or, or if you mess up, you know, let someone know. Um, but, but [00:21:00] yeah, the, you know, a lot of these, these smaller and, and larger structural cracks that, that come from, from lifting errors would be avoided if everybody was doing the same thing or the same two iterations of Of lifting standards, which is really exciting

Matthew Stead: Y- y- if you’ve got a wind farm, y- y- you’re guaranteed you’re gonna have to drop a blade at some point, aren’t you?

Allen Hall: And a gearbox

Matthew Stead: and a generator It’s, it’s pretty much a given. So like, like I said before, I reckon it should just be part of the standard kit that you buy, is you, you, you buy a substation, but you also buy a lifting, a lifting kit as well.

Allen Hall: It’s one of the more, uh, dangerous parts of wind is lifting, clearly, and we’ve seen that over time.

And, uh, having standardized equipment, back to Yolanda’s point, does make a lot of sense because if you’re out there doing this quite often and you have different rigging for every different OEM, you can get crosswise, and things happen. And if we had some standardization there, that would make a tremendous [00:22:00] amount of sense.

That’s why, uh, Safe Lifting wrote this article on PES Wind. So if, if you wanna read this article, just visit peswind.com. When engineers plan an offshore wind farm, they try to account for everything, including seabirds. And at the Horns Rev wind farm in the Danish North Sea, the layout was meant to leave birds a clear way through, but the birds had, uh, ideas of their own.

After 26 years of patient monitoring, researchers found that the turbines did not simply chase wildlife away. Instead, they reshuffled the entire neighborhood in the sky, turning some species into avoiders and others into opportunists. So this has been a big discussion in the wind industry for a long time, particularly for offshore wind projects, of what to do with the birds.

And the early assumption was that, hey, let’s just give them a pathway where they can fly [00:23:00] through, and birds have made up their minds. Some are taking that path. Others are avoiding it because of the change in the which, uh, species are hanging out where. This is a remarkable outcome, and it’s been going on long enough that there’s, uh, some statistical relevance to it now.

Do we need to get some bird psychologists involved in these offshore projects on how we think of how birds behave? Because I think to the engineering community, you know, like, you, you put a road there for you to fly through, bird, and then you decide not to. This is at a different level than engineering.

Yolanda Padron: I think it’s great to do as much as you can do, right? It’s amazing that they did all of this work. It is kind of funny. I mean, it’s, it’s sad. I’ve… I’m, I’m gonna get into trouble on LinkedIn or something by someone. I, I mean, it’s, it’s sad, of course, if, if birds get hit, right? But it’s, it’s, we can’t control everything.

You [00:24:00] know, as much planning that went into this, it’s

And what’s the next step here?

Matthew Stead: Well, first of all, 26 years? Is that correct? Yeah, 26 years. I mean, m- I, my- the thought that came to mind is that sometimes engineers don’t understand the natural environment. Sorry, just, just take that as a, as a observation. But, you know, I- it just reminds me of when, um, when civil engineers lay out paths and pavement, you know, they put a path in, but then people walk around it.

People do whatever they wanna do. And so, you know, I, I don’t think we can actually design out some of these things because we just will never understand the bird, we’ll never understand the human. Um, so yeah, I think put a little bit of effort in. I think going back to what Yolanda said, just put a, a bit of effort in.

But yeah, actually, there are some things in this world we can’t control.

Yolanda Padron: Yeah, I mean, [00:25:00] there’s, there’s of course endangered species. There’s of course, you know, a lot of, a lot of monitoring companies out there that do a really good job. Depending on what you need and depending on, you know… You can tailor your site needs around w- what’s gonna happen, right?

Or, you know, if you know that you’re in the migratory pattern of a particular species- There’s, I know there’s a lot of very smart people hard at work to make sure that your site is tailored to fit what needs to, what needs to happen there. And it’s great. I think it’s a great, it’s great to know, you know, that, that people in this industry care about birds.

I know I once had to go through extra check at TSA because the, the person there said, you know, “Oh, you work in wind? Save the birds.” And then he sent me through this, like, a lot, because he, he thought I was killing birds every day. Um, so I mean, you know, [00:26:00] we’re not killing birds out here, and it’s great, and it’s lovely to see all the hard work that goes into this.

But it, but it also, it’s, it’s important to note that the plans aren’t gonna be 100% foolproof, and that’s okay. You can just try your best.

Allen Hall: What’s the one bird you would assume as an engineer would not care if the wind turbines were there or not? The bird you see absolutely everywhere around the sea.

Matthew Stead: Seagull.

Allen Hall: Seagull. They do not care. They love wind turbines. They’ll use them as perches. I’m sure that, uh, yeah, a lot of, uh, technicians had to deal with seagulls, uh, hanging around the wind turbines. That has to be a thing. So it just depends on the species, for sure. Which is unique, right? E- every species has its own separate personality and things that it likes to do.

Uh, so in some of the wind turbines, I’m sure the seagulls are probably an annoyance, but they’re gonna let them be. And s- and some other species just don’t wanna be around the wind turbines, so even if you put a pathway through them, they’re just not gonna be [00:27:00] there. That’s an interesting finding.

Matthew Stead: It’s like onshore as well.

I mean, cows and sheep love to stand in the shade of a wind turbine, so they like to hang around. They scratch themselves on the, on the, the stair. You know, they, they rub themselves on the bolt covers. You know, they try and eat stuff. Goats, goats are particularly bad.

Allen Hall: Goats are really aggressive on wind farms for finding wires.

Absolutely. An- anything to eat.

Yolanda Padron: Raccoons.

Allen Hall: Yes. Raccoons.

Yolanda Padron: Snakes.

Allen Hall: The snakes do hide out in the shade. That is one thing you gotta be careful about is, uh, especially in Texas, of kicking over a rock and finding a snake, so make a lot of noise when you’re walking in Texas. That’s the plan.
