Business Development in Wind with Joel Saxum
Weather Guard Lightning Tech’s Chief Commercial Officer, Joel Saxum, gives his view of the state of the wind energy business from the perspective of a business development executive. The IRA bill is changing the way businesses are planning, working, and being acquired in the United States. Will that trend continue? And with the current lack of technicians, how do wind energy companies grow their businesses? This is an enlightening discussion sure to sparks conversations at the water cooler (or wind turbine).

Joel Saxum Interview
Allen Hall: I’m Allen Hall, and I’m here with my good friend, JoelSaxum, and on this special edition of the Uptime Wind Energy Podcast, we’re here to talk with Joel, who has recently joined Weather Guard Lightning Tech as our Chief Commercial Officer. And Joel has tremendous knowledge in the wind industry and what has happened over the last couple of years.
And today we get to pick Joel’s brain. And get a sense of where we have gone, where we are at, and where we are likely headed in the next year or two. So Joel, welcome to the program.
Joel Saxum: Welcome, I suppose, for the, I don’t know, the hundredth time or so, maybe? It’s, it’s close to that at this point. Yeah, so Allen and I were talking in the background off air, talking about, you know, what, what is actually happening out there right now.
It’d be nice to kind of drop a little bit of knowledge of. Of what, of course, I’m hearing in the, in the BD circles everybody seems to be connected somehow in this industry. And then also the general trends, all right? And we will touch on a couple of things here.
Allen Hall: So if we go back two years ago to ACP in San Antonio, which is really kind of the first real kickoff.
I know we had O& M previous to that. I think, I think that’s right, right? So we had O& M in San Diego. And, and at that point in the industry, everybody was just coming out of COVID. Those were really some of the first events, right? We had, if we all remember in San Antonio, we had COVID tests before we could walk into the building.
And what fun that was. And at that point in the, in the industry, it was like, everybody was just trying to come awake again. There was a little bit of discontinuity between organizations. You could feel that everybody’s just trying to feel the way around. And technician wise, it seemed, it did seem like there was a huge competition for technicians, like, like we have seen now.
And then as we progressed over the last year or two, it’s really, I think, changed dramatically in terms of the number of players in the marketplace. Even if you look at the number of drone companies that we saw a couple of years ago versus today, dramatically different. In, in terms of just sort of the knowledge base is still see the same key people around in terms of like the, the business development side, it has been a little bit of a rough road, right?
Even with the IRA bill has been a little bit of a rough road.
Joel Saxum: Yeah, absolutely. So, I mean, the IRA bill was designed to spur on projects, right? They say that we’ll, we’re going to get PTC back funds back the case, basically credits back basically back the same way they were. Before the IRA bill was passed, so, you know, every 10 years put X amount of dollars into your wind farms, get them up and running again, and you’ll re qualify for these credits, which I think are like 2.
8 cents per kilowatt hour or something right now. And then on the heels of that was also the ITC which is investment tax credits, which was a 30 percent tax break on things that qualify for it that are in the renewables industry, but built here in the U. S. So it was designed to spur these things on.
Now, to get the economic machine moving, it doesn’t happen overnight. That bill was passed last August, I think, Allen, if I’m correct. So we’re 14 months past it now. And if you look at some of the charts and graphs that the DOE’s put out, you’ll see a lot of little dots and pins put in maps all over the place in the U. S. based on who is taking advantage of it, right? Like who’s, who’s making products and, and starting manufacturing facilities. So we’ve even seen, I guess, like here up in my, my, my home state of Wisconsin the ship builder now, so that even that in it, it’s an offshore As fact, in Crowley building a vessel up here for offshore east coast us.
So that ITC idea in the bill, there has spurred on some, some movement. We’ve talked about some others on the podcast about, you know, a tower factory down in I think it was New Mexico. And some others taking advantage of it as well. You’re finally in the BD world, you’re finally starting to see that happen.
You’re starting to see things where people are going, Oh, well, this person’s now doing a repower because they weren’t quite sure before. I know of one operator where they have Ooh, I think eight or ten repowers that they plan on doing in the next three to four years that weren’t on the docket before the PTC.
Or before the IRA bill and the PTC, new PTC funds were there and these fund farms aren’t the 10 year old ones. They’re 17, 18, 19 year old wind farms that they may even put all new technology on, right? Take the whole nacelle off and put a new nacelle on. So with that will come a ton of work, right? So from cranes to.
It go all the way down to the people that support on the ground getting mats and cribbing and bearings major corrective exchange smart people that do that new gearboxes you know, unfortunately, some of those components will have to come from overseas. But we’ll be all, you know, U. S.
labor installing all of those here and, and hopefully as the ITC credits kick off and we build more things here in country more and more of those components get built here as well.
Allen Hall: Does that, shift in the industry in terms of hardware translate this year, next year? I, I, cause I, I feel like we’re still three, four, five years out.
On the effects of it, just because of the time it takes to build a factory, to build a ship, to… Make a tower factory it it’s slow.
Joel Saxum: I think full swing to feel the real economic impact of it Will be we will be so far removed from the bill passing that you’ll just feel like it’s normal again, right? Like you say like two three years down the road It could be things kicking off and that were really actually tied to the the IRA bill But at that point in time you won’t even really feel it because it’ll just be this is how we do business now because that’s The IRA bills in place for it’ll be in place for a long time So the, the smaller components, the lighter things are happening now, but it’ll take it, but it’ll take a little bit for the major components stuff.
Yeah.
Allen Hall: Right. Even though there’s a lot of talk about offshore wind, because that’s where a lot of the, the auction money obviously is big numbers, make headlines and some of the contracts and the PPAs that are bouncing around there make the news. But the vast majority of, of wind in America is, is onshore and that’s where the action is at the moment.
Right?
Joel Saxum: Yeah, absolutely. That’s actually when I was taking notes for, to, to chat with you today, that was one of the things I put on there. It’s like my second bullet point and focus. The focus in news is offshore wind in the U S it’s this pretty shiny new glittery thing that’s in everybody’s face, but don’t forget onshore, right?
We’ve got 70, 000 plus turbines in the U S. And that is where 99. 99 percent of the action is happening commercially in the, in the United States. That’s where all the, all the companies are working, all the service companies, all the ISPs most all of the parts. Like I said, there is, there is some stuff happening offshore, but the bulk of the economic wind engines here in the States is still securely in the onshore world.
Allen Hall: And that drives all the way down to companies that do crane work and the heavy lift, replacing generators and all those companies you don’t really hear about. I know we put out a recent post asking the industry, Hey, identify these key players in the U. S. industry, U. S. wind industry that are actually based in the United States.
And that list got really short, right? The number of feed, the feedback on that was extremely limited and I know better. I know there’s a lot more players in it, but they don’t. Interact like sort of we do, and they don’t say, Hey, we’re doing this project in Colorado. You just don’t hear anything about it, which is.
Very odd, I think, especially in light of the IRA bill, that you would want to make a little more noise.
Joel Saxum: I think the existing, the existing people in the market, right? Your, you know, your, your Barnharts, your IEAs, DWT, Blattner, all these big companies, the Pearce and, and, and TAKKION. They’re so flush with work right now that they really don’t have to be out chasing stuff, right?
While I don’t want to take this away from this, the, from other people as well, it seems to me that We almost have a little bit of a problem in this industry, and it’s not specific to the wind industry. It is specific to any… industry. If you watch innovation cycles, say in the in the late nineties, early two thousands, it seemed like everybody was starting up a, if you were out in California, right?
Everybody’s starting up this dot com boom. Everybody’s got a little company doing something on the internet. Well, there’s a few of them that rose to the top and a lot of them that got either acquired or just passed by because either their product was not good, didn’t have customer support or whatever.
Innovation cycle happens in all industries. Right, that innovation cycle happened in the auto industry in 1920, 30, 40. How many auto manufacturers were there that just aren’t around anymore and they’ve all either consolidated or, you know, the products went off and that happens in, in, in almost every industry that grows right now, we’re in that in the U S where you see a lot of places you see, you know, every Tom, Nick and Harry starting up a company that, Oh, we do this.
Oh, we do that. On the, at the same time, if you start a company and you don’t have the, you know, the HSE stuff in place and the quality things in place, like you’re going to run into a lot of teething pains, you’re going to hurt, you’re going to feel a lot of pain for a long time. And you can start to see some of these people doing that at the same time of this wicked shortage of labor and even greater shortage of good and trained educated labor that knows what they’re doing, where you don’t have to go and teach everybody everything all the time.
So you have companies that are starting up that might have one or two good smart people in them, and then they brought along a bunch of friends to try to start this thing, and they’re either… And getting in, getting contracts, screwing them up. Other people have to come in and kind of rescue them or there’s quality issues or HSE issues.
And, and so the, the large companies, the OEMs, the big asset owners that are, you know, need all these, these services are getting, Quite bent out of shape about the quality that they’re getting. So while we’re sitting here going, there’s so much work, so much work, so much work, which is true. And everybody’s like, well, I’m sorry to company I’ll do this.
I’ll do that. But then you go to the, the, the people that are using the services and they’re not happy with the results. So you have a kind of a. A weird thing going on there where now, even though there’s all kinds of work to be had, these smaller companies are going like, where is it at? Whereas the big companies are just flush with it.
They’re soaking it in and they’re looking at high need people. So you’re starting to see, I think you’ll see more consolidation of companies. I think you’ll see Tachyon and Pierce and these big guys buying up some of the smaller ones or some of the smaller ones joining together. Just simply because the people that are hiring them are looking for…
strategic suppliers, because they don’t want to deal with this rash of massive issues in the field. They want to deal with one person that can take care of all their problems. So they want to deal with one person, whether it’s, Hey, I got a blade issue, or I need an inspection done, or I have a main bearing that’s, you know, gone, or I have an oil leak or whatever.
They don’t want to have to, I got to call this contractor, got to call this one. I got to call that one and figure this out. It’s that, that’s getting dialed back. You’re starting to see it in RFQs too. I just looked at one the other day that was like, Yeah. You can have sub suppliers, but we don’t want to manage them and we’d rather you not like there was points for not using sub suppliers in it.
And, and, and to me that makes, it makes sense. But that will drive some consolidation because people need resources. If you’re. A, I don’t know, Allen Energy, and you need all of a sudden your biggest client comes you says, Hey, I need someone to change out pitch rams. Well, you don’t have that capability.
Well, I don’t know. Let’s go look for a company that does and scoop them up.
Allen Hall: Yeah. It does seem like that in the United States at the moment, there is a lot of moving and shaking that is below the radar. That you hear about it at conferences, you run into people and say, Hey, did you know that this company is going to maybe acquired by that company that they’re looking to, to, to join up in Europe.
It seems like most of those transactions have already happened that unless you bring something really unique to the marketplace that has not been seen before, that it just doesn’t seem to, to move anybody. And maybe that’s just a different sort of business environment. U. S. versus Europe, but it does seem like the Europeans have shaken this whole system down a little bit and have found the companies are going to be around a while and then focused.
And I agree with you. In the United States, we’re still in that shakedown period. We’re trying to figure out who’s here for the long term and who’s just testing the water a little bit. And does that then force like the operators to be a little more leery of what’s happening? Of, do they, do they do a lot more vetting of these companies?
Are they looking for insurance products to come along with it? Are they monitoring the sites closely when repair work is going on? What are they doing?
Joel Saxum: Well, I think you’re a hundred percent correct on this, the, the acquisition portion, Europe versus America. American, right, America right now is… Grow, grow, grow as fast as you can.
We’re grabbing companies because you need resources. Well, whereas in Europe, it’s more We’ll grab a, we’ll grab a country, company strategically. Strategically being like maybe we’re looking to sell our group and we need to add in some capabilities or something like that. Whereas in the U S it’s just a revenue chase, right?
Everybody like this work is going to be here. I have a shot at it. If I don’t go grab people, I’m not going to get it. So we’re, we’re just not as we’re not as mature. The industry isn’t as mature here as it is there. But back to your, your question about what are the asset owners, the OEMs doing from what I’ve seen, the tender processes are getting more difficult.
They’re asking for again, more references, more, more track record. Like if you don’t have a track record, you might as well not even, I mean, it’s tough to get in on some of these because you’re competing against some good competition, right? If you’re looking for a major OEM or a major asset owner, and you’re a drone company, like XYZ Drone Company isn’t going to get it.
It’s going to be a Zeitview, a SkySpecs, a Thread, like someone, someone that’s there and, and is established now because that industry is there. If you’re a a blade repair company but you’ve only been around a year, unless you know someone in high places, good luck because they, these large companies have been burned so bad so many times that people just aren’t willing to stick their neck out.
Because what ends up happening there, and I’ll go, let me, let me shift gears a little bit, what ends up happening within that, that large company, that asset owner, that OEM, is when they bring on a subcontractor that doesn’t fulfill their needs. It creates strain within their own organization, let alone not getting their product done.
So the blade repairs may not get done, may not get done to quality, but you’re also putting a lot of stress on your internal people. So if you’ve got a site manager that has to manage one person on site or one or two subcontractors, that’s not too bad. But when that one guy on site has to, or guy or gal on site has to manage five different subcontractors and he’s got to be in their operations because they’re not that good at what they’re doing.
And. helping them rig up their platforms or whatever. And he’s just like, why am I paying for you guys to be out here when I have to tell you how to do your job? That happens way more than it should in the wind industry. So what happens is, is these site managers and site supervisors and things, they start getting overloaded.
They start quitting. They start looking because they’re, they’re, then they’re yelling up the chain. Hey, I don’t have enough resources here to manage all these people. And then the people up there, the upper guys that are given the contracts like, Oh, well, you shouldn’t be any problem. You got 30 guys out there that are doing your blade repairs.
Yeah. And I got to manage all of them, you know, so you’re, you’re starting to see, like, I, I, I’ve talked with people, I’ve seen resumes come across from, from OEMs. Hey, like I’m, I’ve just had enough, like I’m done here, you know, like look at what GE just did not too long ago, taking it from all site people to go into hubs.
The, how their job, how all of those people’s jobs changed immediately. And they may have said, well, you were in charge of this wind farm or you were on this one. Now you’re on these four. Man, it’s overloaded. A lot of a lot of people in the field talking about how the managers are struggling a bit with having to deal with just too much.
Allen Hall: Yeah. And that, I guess sort of gets into the next question, which is about technicians, right? So everybody’s getting strained. There seems to be a real lack of technicians, particularly technicians with experience, and we know how tough the industry can be. It’s sort of a young person’s game at the minute, because if you’re fixing blades or out in the middle of West Texas working on stuff, it’s not particularly easy to do, and the industry, I think because it has Doesn’t have a lot of exposure.
That’s a hard time recruiting new talent. And from a business development standpoint, that that’s a real limiting factor on your rate of growth.
Joel Saxum: Yeah, absolutely. I mean, you’re, you’re, you, you, you run businesses two ways usually, right? Demand. On the business side drives demand on the operation side or demand on the operation side drives demand on the business side and you can go either way, right?
You, you pick your poison, however, signing contracts where you don’t have people in them is or don’t have people for them at that point in time. is almost always going to have quality issues, whether it’s quality, whether it’s HSE in the field, whether it’s quality of the work, the repair, the whatever, the communication, like so many times I’ve heard of, Oh yeah, well we got, I just, I need 20 people and you’re just grabbing them.
Here’s a truck head to Saskatchewan. You’re a commissioner now on a, on this project and they’re like, okay. They don’t know how to communicate within the organization, or even have their fuel card work while they’re traveling. That happens all the time. And it’s a black eye on the industry. So, again, this is a conversation I had with Chris this morning, Chris Gagnon.
You know, we’ve talked about on the podcast before about how do we get more people trained? How do we get, you know, there’s, and there’s people opening training facilities. You had Rob Renewables open up their facility in Chicago and, and a bunch of, you know, I know blade repair companies opening GWO training sites and stuff.
And that stuff is great. However, that gets the safety check boxes that doesn’t give people the technical skills they need. Technical skills they need, need to be taught at community colleges or in, you know, internal programs of that sort. And they’re having a hard time getting people just into those programs.
Those schools are. So when we’re sitting there going like we have a shortage of labor an even greater shortage of good trained labor that knows what they’re doing, retaining the techs is even harder once you have them in your company. So once we have a good tech in your company. This is from, from, from us or from me to the industry, treat them well, pay them on time.
Don’t make them hunt money. We see that stuff on LinkedIn. Oh, such and such. We’re hunting money from them. They won’t pay my invoices, you know? So get, that would be to me, if you’re going to scale and grow a company in the wind industry, specifically in the U. S., figure out the HR portion of your company as, and have a plan and have stuff in place before you start trying to scale up.
Because. You, you’ll, you’ll, you’ll be paying or stealing from Peter to pay Paul the whole time going why do we have this attrition rate? Why are these people leaving? Well, if you don’t have a good setup for them and you’re not treating them right it’s just not going to happen for you.
Allen Hall: Explain to me a little bit of valuations while we’re sort of talking topic of people and people turn it to valuations of companies.
And I do think there’s going to be a lot of mergers and acquisitions over the next 12 months based upon the noise we’re hearing. How does, how does that work? Because it does seem like the number of technicians you have in your stable is a part of the valuation process. So I take a technician times, you know, I have a hundred technicians are each valued at X.
I have a 10 engineers are each valued at Y that sort of, plus all the equipment I own, I guess, that in turns into a valuation, but there’s just, that doesn’t always align with what I’m seeing in some of these numbers on acquisitions.
Joel Saxum: Yeah, the tough thing here is, okay, so diving back and this is the base of the technician problem.
Every company operates, not technician problem, the technician conundrum, I’ll call it. Every company operates differently, right? So since wind is, especially, especially blade, blade repair. is such a seasonal market. Unless you’re a big company and you can send people to Brazil or Australia or whatever in the wintertime, you’re up here, you have a shoulder season.
You go up, you get busy as hell and then you kind of slack off. So what ends up happening is, instead of hiring employees, a lot of these companies hire contractors. Well, no intelligent contractor is going to sign an exclusive contract as a contractor unless they’re getting paid the whole year. And no company really wants to do that.
So the majority of these people are free agents month after month after month. So if I’m a blade technician, I might be working for, you know, company Y this week and company A next week. And I might have jumped because a dollar, I may have jumped because I didn’t like the guy I was working with. But either way, you can’t really count on that valuation wise, right?
Unless it was a stable of employees. What I’ve seen valuation wise in the wind industry. Is because there’s so many moving parts like that in different companies and to, to levelize it, to equalize it, you’re of course taking in the standard stuff or your debt, your, your your, your debt ratios, the team you have, those things don’t really turn into, or the team doesn’t really turn into dollars until you get to the end, but I’m seeing a Test.
Depending on who you are, a nine to 14 or a 10 to 15 times EBITDA as a valuation and good faith valuations or good faith additions in the wind industry, I’m starting to see go away when I talk to people. And the reason being is because the market is so volatile. You never know who’s going to get these contracts.
People are jumping around here, jumping around there. That your good faith, good faith being like, Oh, we did 5 million EBITDA this year. Next year we plan on doing seven. So we want to be valued at seven. That’s starting to raise people’s eyebrows a little bit. Still getting good multipliers for EBITDA.
You know, some industries it’s can be two and three ebitda, two ti two or three times ebitda. Tech industries I’ve seen 20 times ebitda, but the renewables and wind is still trading really well. So those that, that, you know, 10 to 15, 12 probably average multiplier for EBITDA is what people are shooting at ebitda, being earnings before income tax and depreciation and amortization.
So basically what’s your revenue minus your operating expenses?
Allen Hall: No. Does that then drive those EBITDA multipliers having looked at that at other industries anything above 10 is sort of a sweet number if you’re selling. If you’re, if you’re getting a multiple of 10 plus on your EBITDA, does that change the way you do business today?
Or should it change the way you do business today? To have that possible merger or acquisition occur so that you can make the magic happen.
Joel Saxum: Yeah. If you’re, if you’re above 10, you’re looking at a company that has on staff engineers. You’re looking at a company that has a good, good support all around, right?
So if you’re. Two guys running a company and you got six blade techs out there. Like you’re not at 10 multiple even a company, but if you are a company that has a dedicated back office person for travel, a dedicated fleet manager an actual engineering group, engineering staff that can support you through operations, if you have processes in place, if you’re ISO approved, if you have, you know, you’re, you’re in an HSE system, that’s been, if you’ve been vetted by, if you have an MSA with Siemens and Vestas, like those kinds of companies are in that 10 to 12.
EBITDA range, but that’s a company that can, that someone looks at and goes, well, they did 10 million in revenue or 20 million in revenue this year, and we believe we can get more and more and more. Well, then that’s someone that’s going to get a high EBITDA. But if someone’s just grabbing you to grab people, it’s not going to be that high.
Allen Hall: Do service agreements. Influence that eat about the service agreements, increase the multiplier. So if you have an agreement with G. E. or Siemens to do work for the next two years, does that really then help propel you into a more stable bracket than maybe a company that’s sort of looking for work month to month?
Joel Saxum: Absolutely. 100%. And, and. It’s not something that you can put a metric to. It’s not like, Oh, you have an at one MSA, you get one time X multiplier extra it. That’s a valuation thing. That’s where you have these big companies, these, you know, Boston consulting group and stuff like that, that you’ll hire. If you’re trying to sell, come on and say, and do a valuation.
And they’ll be able to tell the market, this is why we’re at a 12 or this is why we’re at an 11. And we have. And MSA good through 2026 with GE to do all of their, I don’t know, foundations or whatever your company does. Those, those MS, those master service agreements or ongoing agreements definitely play into the EBITDA multiplier sale.
Allen Hall: So looking at the existing landscape in terms of the business development side, what are real three key areas over the next six to 12 months that companies should be focused on?
Joel Saxum: I think your big one right now, okay, it’s fall. We know that tenders are coming out soon. It’s the beginning of October. So tenders will be out in the next two months for people who are on the ball.
If you’re a company that once worked on this spring, please don’t wait until January or February to put your tender out. But you’ll see tenders for everything, right? For whether it’s major correctives, whether it’s blade work, whatnot. Everybody’s getting their ducks in a row to start off next spring. And the spring season in the U. S., depending on where you are, Texas to… Montana starts in either end of February or May, somewhere in there, right? So everybody’s getting their ducks in a row right now to do tenders. So everybody that’s in the BD world is sharpening pencils, getting a proposal, templates ready, ready to rock to, to receive all these things.
And there’ll be anything from inspections to full blade repairs and, and whatnot. BD people busy with tenders in the next few months. So that’s the big one right now on the docket. You will also. Everybody else that’s chasing work is going, is going to be chasing people doing repowers because no matter what sector you fit into in the wind industry in the US, somehow your product or service more than likely is impacted by repowers.
Whether it’s bolt tensioning or cable sales or our buddies at 3S Lift selling lifts or, or ourselves. The selling strike tape, you know, I mean, it’s, it’s the, the, when those things are coming down, it’s some of the best opportunity to, to upgrade retrofit, get everything ready to, to go for the next 10 years for that wind farm.
So, you know, the, you’re starting to also see, here’s another one that’s kind of popping up, general contractor rep representatives for repowers. That’s the person to, to talk to if you know who those people are at, at these companies and you’re trying to speak with someone doing a repower, that’s a good one to chase.
So tender season is upon us. Also people that are chasing things are chasing getting ready for repower season and repowers can start earlier, right? Because if you’re, you can do crane work, you can start plucking stuff as long as, as long as things are ready to go. You’re not, usually not waiting for resins and epoxies to dry in certain temperatures or anything like that, so.
They’ll, they’re cycling all the time, but again the wind industry is kind of used to a slow winter fuel operation wise. So repowers tend to follow that same path.
Allen Hall: Okay. That’s really interesting. If I was going to choose number three, it’s getting yourself some technicians. Right now.
Joel Saxum: Yeah, yeah, absolutely the tough thing with that is okay, so I’m gonna give you here’s a theory for you Allen This is one of the theories I like or it’s not theory an idea. So when I was an oil and gas we used to operate this way.
I hired Allen Hall as a technician I would pay Allen Hall. I don’t know 70, 000 a year You would get, you’d get, you’d get, so you’d get 70, 000 a year. Okay. And you get that salary year round. So every two weeks you’d get your paycheck deposited. However, for that 70, 000, you owe me 200 days. So 200 days, because because we work in the field remote, it’s, you know, six, seven days a week on site, 200 days during the busy season or 180 days, or however you want to structure the contract.
You may, you may eat, you may eat through real, real fast in the summer, like between April and, and September, man, you might be at 180 days already. Well, that’s good for you. You made your salary. Now, every day that you work extra after that, then I give you, or every hour you work extra after that, then I give you what your hourly rate would be.
So there’s a possibility of a technician that’s working into Christmas. Or November making a really good year. But what that also does is that gives the, that maintains that employee. So you’re, you’re keeping him or her and you’re keeping them happy. They’ve got to, they’re not having to struggle to go, where am I going to go next?
Where am I going to go next? Cause you’re getting a paycheck every two weeks. So they work for you. They’re going to be more loyal to you. They have the possibility of making a bunch of money. And then the other side, the backside. Upside to the company is if you have a group of good people that you do this for and say you are slow, well, then you guys got to come into the office and you got to do training and or, and, or you’ve got to get kit ready.
You’ve got to test PPE. You’ve got to training is the big one. I always, I always like to do. But that’s how we used to do things in the oil and gas world because you’d have people because the jobs were cyclical and you might be out for three months at a crack and then home for a month. Well, you didn’t lose that person.
All the efforts you put into training them and, and getting them up to speed on your processes and how your company works. You didn’t lose that person. They’re there for you when, when you’re ready to go back out to the field. So it keeps them happy and it keeps you able to grow. So that’s, that’s a theory.
That’s how I, that’s, that’s how I used to pay people.
Allen Hall: That’s innovative for wind right now. I think a lot of it is just the hours you work, we’ll pay you and what you’re not working, we don’t pay you and we’ll see you next season, maybe. And I think that really hurts the industry more than you think.
Joel Saxum: Yeah.
Absolutely. So if it was me and I had a company and say, I say, I’m going to go blade repair company. If I had 10 blade teams, that means I’ve got 30 people, 25 people, the 10 leads on the teams. I would set this up. I’d say, Hey, the last three years you made an ad, you made 70 grand, 80 grand, 90 grand, whatever.
So I’m going to give you an average of this much, and that’s going to be your salary. And if you can do that for those key people, keep them around. Then it tends to actually trickle down to because the next guy in line likes working with this guy and he’s like, Hey man, if I do good, I can get that as well.
I can get a steady salary in the wind industry. That’s the kind of stuff we need because right now, like you said, You shouldn’t be going and finding technicians. That’s a BD job as well. Like everybody is a, everybody’s a recruiter in the wind industry, whether you’re client facing or not. So like, so you, you’ve got to be out there pounding the ground and what, and what it is is it’s, it’s attrition.
Like right now there’s no, you know, everybody’s left or getting close to, right, it’s October. So you, you don’t know, you may think you’ve got, you know, Joe and Jessica and Sarah and John for next spring, but you don’t know. Unless you secure them somehow.
Allen Hall: Yeah, it’s the industry. It’s such a fluctuation. I know we like to think of ourselves as being fully established and running full steam.
There are some weak spots and there’s some really good really good growth spots that I’ve seen over the last couple of months where I’m really have been impressed by the companies and the people. That they have assembled, and it’s, it’s sort of an inflection point, I think, in the U. S. industry, and it, Joel, it’s been really good to pick your brain on this, because we don’t get to talk a lot about business development and actually what’s actually happening on the street like this, and I think there’s a lot of, of interested listeners to this, and I’m really glad we had the time to spend together, so everybody this is gonna conclude this episode of the Uptime Wind Energy Podcast.

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.
