Allen Hall 2025: Matt, welcome to the program. Greatly appreciate it. So Matt Sagala has not been on the Uptime Wind Energy podcast. Although he’s been asked for the last five or six years to be on, he has had other commitments. So now that he’s available to be on the podcast, we love having him here.
Uh, if you don’t know Matt Sagala, Matt Sagala is a, a real special talent in wind. Very knowledgeable about repairs. He’s a composites person, but he, you know, it’s one thing to know composites and understand what that looks like, but also to run organizations that repair blades and manage blades and take care of large quantities of blades and do it very efficiently, where the assets are actually working and operating efficiently is hard to do.
So, uh, [00:01:00] Matt is now with SkySpecs in a recent change from a, a large global wind operator, and he’s come over to SkySpecs as Director of Asset Management. So Matt, congratulations first. Appreciate
Matt Sigala: it. Appreciate it.
Allen Hall 2025: So that’s a, that’s a big title there. What does that all mean, Director of Asset Management at SkySpecs?
Matt Sigala: basically, it’s just the overview of your entire asset from the start of the inspections to the reviewing of, of the inspections, to creating the RFP, going out to blade budgets and repairs, uh, and then having the actual repair teams on site and us being able to help execute those repairs in a systematic way, um, without having to overload or, or burden your, your internal, uh, systems in-house.
Allen Hall 2025: Because as an operator, there’s a lot on your plate.
Matt Sigala: Yes.
Allen Hall 2025: And a lot of operators don’t necessarily have blade teams internally. You came from an organization- Yeah … that did have a really good, still does have a really good blade organization.
Matt Sigala: Oh, amazing, yeah.
Allen Hall 2025: Yeah. Uh, that was unique, but a lot of operators in the United States or globally just don’t have [00:02:00] that resource.
SkySpecs has developed that resource over the last couple of years of we’re blade experts, we have all the data coming in, but we can also help you downstream when it comes to maintaining and repairing blades, which is, is sort of a new feature for- Yeah … SkySpecs. Now that you’re there and you’re seeing all the data, all the, the,
the-
the,
data center, so to speak, of w- and you have access to blades globally, and you can put your fingers on it.
What are you seeing out there in terms of blade health and, and going forward?
Matt Sigala: There’s a lot of work. There’s definitely a lot of work upcoming and into the future. Um, and you know, I think a lot of it could be risk-based with, with inspections, annual inspections, semi-an-annual inspections. I think that’s always the first line of defense on any blade management c- campaign.
Um, and then, you know, coming behind that, I think that’s where our preferred vendor lists and, uh, you know, being comfortable with working with certain suppliers on certain type of repairs. Um, we feel that, you know, we have an edge on the industry, [00:03:00] uh, with the data set that we have in hand, plus being able to build a relationship with ISPs.
And not only build a relationship with them, but be able to continuously give them mindful insight to their repairs from a year now to two years now. Because we’re the only ones really seeing those inspections and the repairs after they’ve been in operation for more than a year. It’s very rare that a, an ISP, uh, even on my side of the house when I was working with EDF, of being able to see a repair from year to year.
Um, I think that’s, that’s, that’s pretty massive and- Yeah … a lot of value within that, so.
Allen Hall 2025: Oh, sure. Uh, you were one of the first ones when I met you years ago now, uh, that was a big proponent of more inspection. Yeah. That there are some blades in which you must inspect more.
Matt Sigala: Yes.
Allen Hall 2025: And here’s the reason why.
Matt Sigala: Yeah.
Allen Hall 2025: Because you had thought through it a little bit and you’d come up with a plan. So you always had a plan. That’s one thing about Sagales, he always has a plan. You can ask him any question, he’s got a plan in relationship to blades. And you were the, you were the one that has said, “Hey, uh, there are certain blade types out there that we have seen that, well, you need to do a [00:04:00] little more inspection, and there are some others that it’s totally fine.”
Yeah. A, a yearly inspection is, is, is fine. Well enough. And that SkySpecs data, now that you have access to it, is that also f- feeding back into your- Definitely … logic of that?
Matt Sigala: Yeah, yeah. How do you, how do you think about it? No, it’s, it’s, it’s opened my mind a lot kinda getting me out of just being in, like, the trenches of certain decisions and being able to see this whole data set as a whole now.
Uh, and holistically, it’s like, all right, m- there’s just certain things that I kinda need to adjust on my end. Um, definitely letting a lot of things just play out for, uh, this repair season and, and how things are running, and then kinda looking to make some changes into, into ’27. Um, but the data set, it’s, it’s amazing.
It’s, it’s almost over- overwhelming. Um, so just kinda going after- the low-hanging fruit as far as, like, the 62 twos, the 145s, and really understanding what those look like, uh, how we can help our customers
Allen Hall 2025: that’s a large part of the fleet in the States, but globally too. SkySpecs has made a lot of, uh, recent advancements into, uh, certain marketplaces outside the US.
Mm-hmm. I won’t go into the specifics there, [00:05:00] but e- essentially, like, SkySpecs is becoming definitely more of a global company than a US-based company. Uh, and seeing turbines from outside the US, so you see a, a GE or a Vestas turbine operating in Germany or in the UK, and you see the same turbine in the States.
They’re not- No … performing the same, are they? No. It’s a completely different- Same turbine.
Matt Sigala: Yeah, different wind regimes, erosion characteristics, crack propagation rates, everything. Even we were seeing major, you know, differences from the West Coast to, to central Iowa with the same type of platform. So you can only imagine, you know, start going from a, a larger scale on, on the globe,
Allen Hall 2025: So you’re ac- because you have access to the data now, does that change the way you think about Blade management.
Matt Sigala: Yes. I-
Allen Hall 2025: in terms of when to, when to inspect, when to repair, or just leave it. Are you able to have clear definition of the variables that go into that equation?
Matt Sigala: Definitely so. and I think that’s the key to it. It’s, it’s, we- we’re really stepping away from that blanket approach of inspections where you [00:06:00] do have your baseline inspection, but after that you start getting into the granulars of, okay, you know, this site has X amount of the 622Ps or whatever they are, uh, we need to inspect more on, on a biannual or semi-annual inspection.
Um, and then we have, you know, certain turbines, like you said, that we, we touch once a year and it’s kind of just, just let it go. But, um, no, it’s, it’s very site specific, um, on-
Allen Hall 2025: That’s what I’m wondering … on- Is it how, how site specific is it? Very, very,
Matt Sigala: very site specific.
Allen Hall 2025: Really? Yeah. It’s- So like, uh, is Central Iowa is different than Central Kansas-
Matt Sigala: Eh
Allen Hall 2025: in a sense, or is it more broader spread than that? It can
Matt Sigala: get a little bit broader spread, but then we start looking into s- serial numbers for manufacturers, issues. Okay, are we seeing a certain batch that was released out and it’s in, you know, the northern part of Iowa or half the park? And so that’s what we’re really getting down to now is like serial batch issues and, and trying to track that across the region.
Allen Hall 2025: SkySpecs has been trying to use more AI over the last- Yes … six months to a year. Is that helping to sort through some of that data?
Matt Sigala: Yeah, it’s accelerating it. Uh, definitely it’s not like the, uh, [00:07:00] all end answer, but it’s definitely, it’s, it’s-
Allen Hall 2025: So you’re not just thumbing through Excel spreadsheets- Yeah, no
and looking at them one by one, you can actually use some, a little bit of
Matt Sigala: AI to- A little bit … to sort it. Yeah, Yeah, sort it out, get a high, high res summary, and then being able to kind of like pinpoint where we wanna go from there on it and, and dive in. But still, you know, AI hallucinates and, and does its thing.
Oh, sure. And so we, we just, we wanna tread carefully with it, but making sure it’s clean,
Allen Hall 2025: a sanity check, right? Yeah, exactly. While you’re there, a sanity check, like does that make sense? Exactly. Oh, okay. Exactly. Let’s, let’s scrape it again. Okay. So that’s a huge advantage, and I, I know on the repair vendor management side- Yeah
which has been a, an effort over the last year or two from SkySpecs, is to, uh, work with the ISPs and make sure that they’re doing the repairs properly and they’re vetted and they’re trained. Yes. That’s been a big effort in- internally in SkySpecs for a little while. Bringing you on really ramps that up in terms of the, the horsepower that SkySpecs can apply to that.
Yeah. Where are you going on that, uh, repair vendor management and the ISPs and the data that comes from, from [00:08:00] all of that side of the business, you know, opposite of the inspection side?
Matt Sigala: Yeah, so with RVM, you know, my end goal is, is to have a preferred vendor list of contractors within SkySpecs. And I’m more thinking of them as like a toolbox of not just it being a crescent wrench, it’s more of, okay, this ISP is good for bulk LEP installation.
This ISP is good for Vestas wrinkles, you know, within the max cord. And, and so I think that’s where what I’m trying to, to map out now is, is kind of put everyone within their right socket place of, uh, where they belong in the toolbox- Sh- sh- sh- … and how I can be able to utilize them. And then actually from there, um, seeing what the bandwidth is.
And I think that’s like the real catch is being able to get- The right teams on site quickly, you know, when, when you run into those situations, and safely.
Allen Hall 2025: Yeah, because it’s hard. If you call up an ISP and say, “Can you come fix my leading edge problem?” No. Pretty much the answer’s always yes. Yeah, yeah.
Right? But you need a little bit of a sanity check there. Can they really do it when they got twel- 12 crews out right now? They only have 13, [00:09:00] so probably can’t do it right now. Yeah,
Matt Sigala: exactly.
Allen Hall 2025: That’s where SkySpecs can help sort that out a bit.
Matt Sigala: Yeah, you know, on the QAQC side of things with, like, LEP where you- do
your 10 meters or 12 meters of, uh, LEP installation, and you’re trying to take a picture of 12 meters or, or 10 meters of, of LEP installation both, on both sides.
And so the reports are subpar. I think that they’re good enough, but what I’d like to start implementing is being able to have a, a post-installation inspection after the turbines have been running for three days to a week. Let’s refly, you know, the leading edges and get an idea of how the actual installation quality was.
Uh, ’cause I- in my opinion, you know, anything within the LEP that there’s a defect, it’s gonna pop up within that first two weeks of operation. Yeah. I think that’s something where we can capitalize on making the ISPs get back on that blade, fix it before they get offsite, and have prevent remob and, and such.
Allen Hall 2025: Ooh, that’s a good idea. Yeah. Because a lot of times they’re demobed, they’re down at the next wind farm- Yep … or maybe in another state, and it’s, like, too late to get them back there to, to touch up. To touch
Matt Sigala: up.
Allen Hall 2025: Exactly. To do [00:10:00] minor work usually. Yeah. Uh, it’s usually m- not major stuff. It tends to be minor stuff, but to catch it- Yeah
is really important. So the Horizon system that, uh, an existing SkySpecs,
uh,
customer uses is, there’s a lot to it, right? Yeah, yeah. So there’s, there’s many branches to this tree. One of them is repair vendor management. Uh, obviously another one’s inspection and the, and one of those growth branches is solar.
Matt Sigala: Yes.
Allen Hall 2025: Uh, what is the movement on solar within SkySpecs and repair vendor management? Is that something you guys are working on? Uh, and what, what is the plan for solar? Yes.
Matt Sigala: It’s the, the same approach as RVM, um, where, you know, solar-wise, we, we still wanna be able to, you know, step in and then be that middleman of being able to inspect, be able to get your asset back up and running with, our preferred vendors, you know, and, uh, just have a more smoother, systematic approach to, to the, the maintenance side of the solar s- side of things.
I think [00:11:00] we’re, the blades, we got an early start on it from 2016, 2017 timeframe, so we’re, you know, well 10 years into this. Uh, and I think we’re at the point where, like, solar starts n- need to catch up, and I think SkySpecs has a, a big headstart on that.
Allen Hall 2025: Yeah. Just even on the inspection side, although, uh, solar inspections have been happening for quite a while- Yeah
the, the quality has varied quite a bit.
Matt Sigala: Yeah. The, the amount of data, uh, that I’ve, I’ve been learning is it’s, it’s- … 2, 3X compared to, to, you know, what we’re pulling off off blades. Um, and so- Oh,
Allen Hall 2025: sure …
Matt Sigala: there’s t- tons more, you know, solar data that needs to be captured and, uh, processed.
Allen Hall 2025: Thermal imaging.
Matt Sigala: Thermal imaging.
A bunch of
Allen Hall 2025: that, right,
Matt Sigala: inverters. Top of the panel, bottom of the panel. Right. Yeah. Um, so that’s where I’m seeing a lot more, uh, data management is needed on that side too. And, and
Allen Hall 2025: the, the vendor management of, of that tends to be a little more of l- the Wild West, in my opinion. Yes. ‘Cause the ISPs and wind, there’s a competency to it, and there’s a lot of training- Yeah
to do those things. To be a composite repair technician, you generally have to take- Some training, be out in, in the real world working for a couple of years- Yep … before you become competent at it. Solar doesn’t tend to be that way.
Matt Sigala: No, [00:12:00] no. They’re very, they’re very John Wayne, I guess, like you said, the Wild West- Yeah
of, of, of, of it. But, um- Yeah, it has to
Allen Hall 2025: move fast.
Matt Sigala: It does, and I think that’s where, you know, SkySpecs can really help step in, uh, and be that technical bridge between the financials and the technical, and being able to safely execute, you know, uh, replacements, repairs, et cetera on, uh, on the, the solar side of things.
Allen Hall 2025: Let me ask you a couple questions- Okay … about carbon fiber. Okay. Because I would be remiss to, to let you go without talking- … about carbon fiber, because it comes up a lot in discussions we have at Weather Guard- Yeah, definitely … with operators, be like, “I’ve got these carbon fiber blades. I don’t really have a good track record of repairing them.”
Matt Sigala: Yes.
Allen Hall 2025: Or, the repair is complex and I really can’t find an ISP that knows what to do there. What are some of those repair inspection issues with carbon blades that may differ from your standard fiberglass blades that we’re all used to?
Matt Sigala: Uh, it really depends on where the carbon’s at. So if, you know, we’re talking about a spar cap, um, you know, with unidirectional fibers being- A pultrusion Pultrusion.
[00:13:00] Um, you know, the, the repairs are, are becoming more and more trickier, uh, mostly when you start in- introducing oil ingestion to a lot of these turbines that have carbon. you know, we’re, we’re having to take a lot more steps in, in the repair process, in making sure that we’re executing the repair properly.
And then another thing that w- you know, with the carbon that will– seems to be an issue, uh, on the procurement side is being able to order, uh, you know, the right GSM UD directional prepreg carbon and, and being able to get that in the, into the field, um, just because it requires freezers and, and everything else.
There’s, there’s a couple more steps to, to the prepregs. But, Carbon loves lightning.
Allen Hall 2025: It does.
Matt Sigala: It’s, it’s unfortunate. Yeah. But, you know, it’s, it’s, it’s, uh, a, a whole different repair process, to be honest.
Allen Hall 2025: Well, that’s what I’m hearing- Yeah … is that a lot of operators don’t want to touch it, especially if it’s in a pultrusion form.
Yes. If it is a hand layup carbon fiber structure, uh, from the OEM, that’s a little different than if I had this preformed,
uh, all unidirectional-[00:14:00]
Plank … y- Yeah,
this
kind of brick- Yeah … uh, of, of carbon. That’s hard to kinda grind into and get the layers back like you want to. Is it really repairable? I- and, and it’s in a sense, like is it repairable uptower or is it a downtower thing?
Matt Sigala: Um, no. The majority of the repairs… So I like to think of it if you got your… You break your blade into three sections. You got your max chord, your midspan, and your tip. Yeah. Uh, midspan tip, we, we can get away with uptower carbon fiber repairs.
Allen Hall 2025: Okay.
Matt Sigala: they do require aviation skillset as far as- Yeah … um, hot bonders being able- Okay
to pull your vacuums. And, and it’s… The big thing with the carbon prepreg is that you have to get above 80 C, and you’re more into the 140 C, 160 C, and you’re letting it heat soak for, for quite some time. Yeah. And that’s where you need those aviation style hot bonders and being able to get up there because alternately, it’s, it’s you’re having to soak the carbon at 80 C for six hours or eight hours, a little bit longer to, to get that full, full cook.
Um, and so that’s why right now I think there’s only a [00:15:00] very few qualified vendors out there, um, to do the carbon fiber repairs. it’s, it’s something that’s trainable. It’s not black magic. Um- No … it’s, it just takes time. It’s a different technician skillset. You go from reading layers and seeing your biaxials and UDs when you’re, when you’re grinding, to the carbon fiber, it’s all one layer.
It’s all black. Uh, so you, you’re, you’re more using y- uh, micrometer, and you’re, you’re taking your GSM of what your glass you’re gonna replace it with. You’re micing it. Okay, this is four thousandths or whatever, and then you ki- okay, now I’m like at 16 thousandths, X amount of layers, and now let’s go back.
And so it’s, it’s, it just takes time. It’s a process. It takes
Allen Hall 2025: a lot more time-
Matt Sigala: Yeah …
Allen Hall 2025: for sure. A lot. It- does that then lend itself to more training and qualification verification on, on the skillsets that’s out on site? Which is one of the things that repair vendor management at SkySpecs does, right?
Definitely. You, you’re, you’re- clocking each technician of what their skill set is. So if you see a guy out there that only has fiberglass repair, but they’re [00:16:00] working on a pultrusion repair, that’s sort of a red flag- Red flag,
Matt Sigala: yeah …
Allen Hall 2025: in SkySpecs,
Matt Sigala: right? Definitely. Yeah, definitely. Or not try- Well, understand the process, where they’re coming from.
Did it, was it an approved re- repair plan? Um, and a lot of these sites too, like I said, where, you know, they can’t get prepregded carbon, so we’re, they’re using, you know, GSM 600 UD fiberglass on- Right … some of these repairs.
Allen Hall 2025: Yeah.
Matt Sigala: Um, which is not ideal. Not perfect. Yeah.
Um, but, uh, if, if you gotta get the turbine up in operation, it’s understandable.
Allen Hall 2025: Oh, sure. Yeah. So what are the other big things that you’re seeing out there today? ‘Cause there’s a lot of work going on. There’s a lot of repower work going. A
Matt Sigala: lot of repower work. the whole 80/20, uh, right now, that’s kinda what I’m trying to understand is, uh-
which companies are out there actually, uh, replacing blades, or is it just a gearbox generator, uh, repower, you know, where, where is the money need to be spent. Um, and then trying to understand, too, like the, uh, LEP, um, installations, VD- VG installations, uh, being able to get those on top of, uh, the repowers I think is, is a massive win.
Allen Hall 2025: [00:17:00] Yeah. I, I, we have seen a lot more, uh, leading edge repair over the last two years, uh, mostly c- because of the, the changes in the law. Also, VG’s going on. Mm-hmm. Which you didn’t necessarily see, especially like three or four years ago. Yeah. You would occasionally see it because operators know they get some more power.
Matt Sigala: Yeah.
Allen Hall 2025: Are, you’re seeing more of that just to get to that 80 percentile threshold- Threshold … on, on, on the starting the tax credits over again Are you guys involved in, on some of the advice, uh- Yes … how to go do that? Because I know a lot of operators, like VGs make sense to me, but I don’t know anything about them.
I’m not an aerodynamicist. Yeah. Just, Matt, does this make sense to go do? Is, is that some of the conversations you’ve been involved with?
Matt Sigala: Yeah, we’re getting there. Like I said, I’ve only been here for a month now, but, but- Oh, come
Allen Hall 2025: on …
Matt Sigala: yeah, the con- 30
Allen Hall 2025: days is plenty.
Matt Sigala: The, uh, the conversations are definitely there.
and that’s something that we’re actually looking at in- in house and how we can partner up with, you know, s- certain assets out there that, that can, you know, feed a little bit more data into us. It’s creating like a, an aero packet of being able to- Mm … [00:18:00] install leading edge protection and then apply a VG, and then get yourself out of that neutral area and get you actually making the additional 1.4% energy or, you know- It’s a lot of money.
Yeah, it is. In
the- end, it’s, you know, times these massive fleets, it can add up pretty quickly.
Allen Hall 2025: What’s your feeling on instrumentation of blades today? Are, are there blades that you, yes, you must be putting some sort of instrumentation on it. I’m thinking about, uh, root inserts is a big problem. Yeah. There’s some cracks on certain blades that seem to be almost ubiquitous.
And then, uh, there’s, there’s some blades that, you know, just seem to keep turning. Are, are you thinking about how SkySpecs gets data into the system? Are you starting to recommend, like, “Hey, uh, we definitely need to put some sensors out there to monitor this crack and just to watch it grow instead of yearly may not be enough”?
Or, or is the drone inspection enough? Or you’re, are, are you thinking about vibration sensors? How, what are you thinking about in terms of blades? Yeah, there’s
Matt Sigala: definitely, definitely a need for, for sensors on certain [00:19:00]turbines. Um, I think at some point the visual inspections aren’t, aren’t enough, even on, uh, you know, quarterly.
Um, I’d still feel that a, a visual inspection, uh, you know, 30, 40% of the story. Uh, and then after that, you know, you’re kinda having to either internal inspections or getting hands-on inspection type situation. But, um, it’s more the financials of going out and having to reinspect the blade. If you’re continuously inspecting the blade, it’s, it’s almost easier to have the sensors on.
Uh, but it’s- The lack of data to put those sensors on to actually have, you know, good feedback is, it’s-
Allen Hall 2025: Well, that- that’s one of the things I was thinking about SkySpecs not long ago is because you touch so many blades- Yeah … it, it may make sense that SkySpecs maybe runs a couple of test sites. Like, we’re gonna put sensors on some of these blades to see how this crack progresses, because I’ve seen it in Illinois, in Kansas, in Oklahoma.
If I, me, SkySpecs, have a data set that says, “This is how it progresses,” that could make sense. Yeah. Because you, what you would hate to see is, like, every [00:20:00] operator be doing the same thing over and over and over again. Exactly. Trying to learn the same lesson, where SkySpecs can be a focal point in that. Yeah.
Matt Sigala: No, I think that’s, that’s, uh, something that we, we could be working towards. Um, it’s definitely, you know, not in, in the making right now, but, um, some of this, you know, data keeps coming towards us. It’s, it’s something that we wanna, you know, stay sticky with, so.
Allen Hall 2025: Yeah. And, uh, let’s, let’s go back to the, the repair vendor management side.
Mm-hmm. Uh, I know talking to you before the move to SkySpecs that you had tracked Every technician in terms of their efficiency, the quality of the work, how they… And beyond that, like- Yeah … how they work with others. Do they show up on time?
Matt Sigala: Yeah.
Allen Hall 2025: Is that part of the thought process coming into the larger scale Horizon SkySpecs system is we need to be measuring things than just did they finish the turbine and move on?
Matt Sigala: Exactly.
Allen Hall 2025: Is, is, is that gonna be, you see more of that, you think-
Sigala: Yeah …
Allen Hall 2025: over the next couple of
Matt Sigala: years? I think it’s, it’s gonna be very, you know, ad hoc with each individual customer on, on what type of, you know, data they wanna track, but it’s literally [00:21:00] just a switch within Horizon to turn that on if, if, uh-
Allen Hall 2025: Wow, I, I, if I’m an operator, I’m 100% turning that on.
Matt Sigala: Yeah. No, and I think it’s more of, uh, it helps the ISPs because the technicians know that their names are actually tied to it rather than them just going in there and doing a report, and we kinda get to see who they are at the end of it, so.
Allen Hall 2025: Yeah.
Matt Sigala: Um- ‘
Allen Hall 2025: Cause there’s a big boon to technicians. Oh, massive. If you’re a good technician, man, you can get a lot of street credibility because you’ve demonstrated it time and time again, and you have a- Yeah
a, a whole data set that says, “Hey, I know what I’m doing.” Mm-hmm. “You should be hiring me.”
Matt Sigala: Yeah.
Allen Hall 2025: That’s extremely valuable.
Matt Sigala: That’s something I, I push to the technicians even when I was on the other side of the house where, you know, doing interviews for hiring technicians. W- we’d ask, like, “Do you have a, a, a portfolio?
Like, you’re asking for X amount of money, like, you should have something to show for.” Some pictures. Pictures, previous repairs, you know. Start, s- definitely recommending to the technicians to-
Allen Hall 2025: Yeah …
Matt Sigala: you know, build a portfolio for yourself ’cause it’s, it speaks more than a resume at times. It’s a
Allen Hall 2025: profession.
Matt Sigala: It is, yeah. You
Allen Hall 2025: need to treat it as a profession. Yeah. It’s a
Matt Sigala: skill- It’s not
Allen Hall 2025: just a job …
Matt Sigala: yeah, a skilled trade, so.
Allen Hall 2025: It, [00:22:00] it, it really is, especially now as- Yeah … as we get into more carbon and complex blade designs, and everything’s just getting more advanced than ever. Yeah. You’d have to have that skill set.
Matt Sigala: Yeah. And I think it takes at least a minimum of three years to become a, a good blade repair technician or any type of technician in general. Like, you know, first year you’re learning. Second year is imposter syndrome, and third year you’re finally kinda getting into the groove of things and, and making some decisions.
So, um, and mostly, you know, hanging on a 5/16 cable, you know, 180 feet off the ground. Um, it, it takes a lotta, lotta training and development with those technicians, and just finding the right mindset right off the bat. It’s, like, the first thing that we look for.
Allen Hall 2025: So what are the things that operators should know going into this repair season and in towards, you know, inspection season, which will start in a couple of months?
What should they be thinking about going forward here based on what you know now, now you’ve been on the data side of it?
Matt Sigala: There’s a lot of work coming. There’s a lot of work to be distributed out there, uh, across all of our, our customers. Um, [00:23:00] but there’s a, a massive lack of quality, uh, within the ISPs. Um, and like, like I said, I think it’s not due to the It’s like, I think majority of it’s due to the rapid expansion of, you know, the volume needed for, for repair teams, and it’s constantly growing each year.
And, um, you know, these owners are being pushed a little bit harder to, to spin up these teams to, to get out there. Um, biggest thing is just, you know, taking care of the little steps, you know, making sure all your lines are drawn out on the blade. Like, that’s the stuff that I really see- … our engineers, you know, on, on the q- uh, quality side two or three.
Um, marking is just, you know, minimal stuff to where it doesn’t paint the full picture of the repair on the blade report, and so that’s why we’re raising the flags. Um, it’s not that they’re just going out generally and doing bad repairs. It’s just, like, the little steps in between. I think that’s what we’re kinda, like, focusing on.
other than that, just being safe. You know, these, these guys are, are, are, uh, like I said, hanging up on the, on those ropes or cables and, um, you know, making sure that, you know, they get home safe is, is w- our [00:24:00] biggest thing at the end of the day, too. It’s not only just getting the repairs done, but having the ROI, but it’s making sure that those technicians can, can have a, a safe job to come and go to and, uh, you know, be there, so.
Allen Hall 2025: Well, it’s, I’m sure SkySpecs is thrilled to have you. At least everybody I’ve talked to at SkySpecs is thrilled to have you there, and it’s like y- you’re plugging in this really knowledgeable person into this massive data set. And when you combine those two, you know, it’s, it’s squared. It’s not double, you know?
Yeah. It, it’s, it’s gonna really help SkySpecs out a lot, and I’m super happy for you. I think this is the right s- position for you to be, and eventually, like, you just gain so much knowledge. You-
Matt Sigala: Definitely.
Allen Hall 2025: You’re just one of those guys that you, you just think, “Man, Matt knows so much.” And if you haven’t talked to Matt Sagala, or you haven’t talked to SkySpecs, or maybe you are in SkySpecs, you’re in the Horizon system, and you just haven’t turned on the repair vendor management, now is the time to do that.
Matt Sigala: Definitely.
Allen Hall 2025: Matt is a powerhouse here. He can help you, and the, and the whole team at SkySpecs. There’s a lot of people behind the scenes- Oh, [00:25:00] tons … that are- Yeah … are making this thing go. How do they get ahold of you, Matt? Do they go to LinkedIn or-
Matt Sigala: LinkedIn, yeah. Um, or I can, you know, drop my, my email address with you, and you can put it up there.
But, uh, yeah, don’t hesitate. Reach out, or if you see me around- … um, you know, give me a call. Grab
Allen Hall 2025: him.
Matt Sigala: Yeah. Grab
Allen Hall 2025: me. If you see Matt, grab him. Yes, Matt, it’s so great to have you on the podcast. We’ve been trying so long to do this, so it’s, it’s great to have you here.
Matt Sigala: Likewise. No, this was fun. Greatly appreciate it.

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow.
Allen Hall: Lars, welcome back to the podcast.
Lars Bendsen: Thank you so much, Allen.
Allen Hall: A lot has happened since I talked to you last. I saw some of the announcements on LinkedIn. I was really excited for you. So AC883 has news.
Lars Bendsen: We have news. It was about a month ago now, but yes, things have been going very well.
Allen Hall: Muehlhan has acquired AC883, which is a company you started how many years ago?
Lars Bendsen: I started AC883 12 years ago. From my dining room table, basically.
Allen Hall: Wow. And it’s grown to quite the business over time.
Lars Bendsen: Yes, we have been expanding, especially the last five years after my son came in. He has been the main driver, so we’ve been expanding like crazy the last five years. And, well, getting older. Now we are at a point where we should extend, spend more. And then when Muehlhan, one of the biggest companies in the wind industry, looked our way, it was an easy decision to make. Very easy.
Allen Hall: Muehlhan is well known for being a leader in the ISP world in Europe, and a little bit in America. They’re still making a presence here. That’s why they wanted to talk to you, I’m sure, because AC883 has a nice Canadian market. People trust you and rely upon you, because you bring the quality people over, plus you have all the resources to get to parts that you can’t acquire in Canada and the United States. You know who to call. It’s part of that Danish connection. And that makes a lot of sense, because I do think as we see the industry mature, those quality companies like AC883 are very valuable. They see them as being a huge resource to the industry.
Lars Bendsen: As I said, it makes us really proud that a big company is looking our way, and it’s been a very smooth transition. As you were talking about earlier, the industry is maturing, meaning also big is getting bigger, and you need more horsepower, you need more muscle. And we also needed that, because we’re expanding and there’s only so much we can do. And we’re all getting older, so at a certain time you have to do something.
Allen Hall: Sure, but it comes at a point where you’ve proven yourself time and time again. How many times have you grown an industry in your lifetime? You’ve done it many, many times. That’s why AC883 has always been the relied-upon source for so many things. Now Muehlhan brings a lot of advantages and a lot of horsepower to the organization. Because as you have gotten larger, you realize there’s a lot of back office things that need to happen. Safety, gear, equipment. It’s not just putting technicians on ropes out on site. There’s all the management of that. That’s where size matters.
Lars Bendsen: Size matters, and also the whole health and safety perspective. You’re putting more staff behind the scenes than actually in front of the scenes. So it’s also extremely expensive. And now we’re expanding our offering, because under the Muehlhan umbrella we can do everything, including main component changes, which we didn’t do before. We decided before that anything we need a crane for, we do not do.
Allen Hall: Right, I remember that.
Lars Bendsen: Because it’s a completely different animal from a health and safety perspective, equipment, et cetera. And now in Canada, the company we’re going to be merging with, that’s what they do. They’re really strong in lifting and really strong in installation of turbines, complete wind farms. Where we are strong on the O&M side. And our primary customer is the asset owners.
Allen Hall: Asset owners love you.
Lars Bendsen: We hope so. We think so.
Allen Hall: I know they do.
Lars Bendsen: Where the other company is more focused on the OEM side. So there’s actually a really good mix in that. And we don’t step on each other’s toes, because we are focused on the O&M part and they’re focused on installation of turbines. So it’s a perfect match in so many ways.
Allen Hall: And particularly in Canada, because the Canadian market is poised to put a lot of turbines up in the next couple of years. But at the same time, there’s an older fleet there, and spare parts is an issue. Some of the blades and the repairs are a little more complicated just because of the age of the turbine. And there are a lot of spares and components that you have access to and can bring into the Canadian market. You keep those turbines that are 15, 20 years old running.
Lars Bendsen: Yes, we’re in a sweet spot in that respect, where the turbines are getting older but they’re not too old. So we need to keep them alive. And also, many owners still have the high PPA, which also means they want to do it. So there is a growing market for the O&M component, no doubt about it. But also, whatever happens in the US, leave that aside, they have a lot of good stuff happening in Canada on the offshore side, on the East Coast.
Allen Hall: Oh, yes.
Lars Bendsen: Nova Scotia. There are four big projects going out to bid, I think, within a year or so, and a lot of new projects coming up. So no doubt about it, Canada is a growing market. Where my impression is, and I have to be careful not to say too much, maybe the US is more a stagnating market. It’s maybe not growing as fast as it used to be. Of course, I don’t know enough to be smart about saying it. I’m just saying my impression is it’s more a flat market.
Allen Hall: Today.
Lars Bendsen: Today, today.
Allen Hall: But tomorrow it’s something else.
Lars Bendsen: That’s the charm of the unpredictability.
Allen Hall: Exactly. Welcome to wind, right? It’s unpredictable. Well, I think that’s good, because the Canadian market is one of those pieces that a lot of Americans don’t pay attention to, because it’s not the same scale.
Lars Bendsen: Not yet. But also from the European side, every time we have talked to European vendors or customers, it’s “yeah, be in America.” Yes, but I’m talking Canada. Canada has not even been on the radar. They’re talking about it as of late, but they had not talked about anything else before. So now it’s coming on the radar. And I know the Muehlhan people are smart people. They might be seeing that too.
Allen Hall: Oh, I would imagine, yes.
Lars Bendsen: So I have no doubt that it makes sense. The other thing that’s critical, of course, the US is big as well, but Canada is area-wise extremely big.
Allen Hall: Same width as America, roughly. That’s a big territory.
Lars Bendsen: But that also means it’s further between the turbines. That means you can travel like crazy to meet very few clients. And that’s why the one company is in western Canada and we are in eastern Canada. That makes sense. There are many reasons why you have to be local in your area.
Allen Hall: Part of that is what’s happening in the United States at the moment, but it’s also on the part of Canada to react to it in a positive way. Like, if America’s not going to do it, well, we’re here. We have great wind resources in Canada. And that’s what the Canadian government is saying to itself, I think. They’re realizing the opportunity to go after that wind resource is now. And not only that, because of the way America has situated itself, they can sell a lot of that power that’s going to be generated in Canada right down to the East Coast of the United States.
Lars Bendsen: Yes. Well, the whole AI, the whole data center stuff. It takes seven to eight years to build a power plant. Normally they put a wind farm up in two years. You can’t avoid it, whether you want to or not. I think the Canadians are a little bit optimistic right now, to say, “If you don’t want to do it, we will do it.” And I think we are very happy, and we will see by the end of 2028 who’s happy where. But it’s all good.
Allen Hall: Right.
Lars Bendsen: It’s all good. But again, by that time, well, only now I’m retired officially, so…
Allen Hall: What does that mean? What does retired officially mean?
Lars Bendsen: I don’t know. But I’m retired in the respect that Muehlhan bought the company, and Jannik, my son, who’s been running my company—
Allen Hall: Jannik is awesome.
Lars Bendsen: —he’s been running my company anyhow the last three years. So there’s no change in personnel, same person, people know the same him. Same place, same locations. Nothing has changed at all. Same reasons as before. We just have more horsepower and more offerings to do, and we’re very happy, because we needed that too. Just the whole thing about main component routines. Now we can do it. We couldn’t do that before.
Allen Hall: There’s a lot of need for that.
Lars Bendsen: As you said, the aging fleet, they need to do main components. We need to lift a whole rotor down, different stuff. So that’s good.
Allen Hall: Isn’t that exciting, though?
Lars Bendsen: It’s very exciting. Especially for our team. And I’m so proud and happy sitting on the sideline and following it. It’s amazing.
Allen Hall: Well, you’re not going to sit there and let them do main component exchanges without going and watching that, right? You’re going to have to go at least take a look at that.
Lars Bendsen: I can’t go on site, so I can sit from the highway and look at it.
Allen Hall: They’ll give you a hard hat, don’t worry.
Lars Bendsen: Oh, I won’t do it.
Allen Hall: Safety glasses and steel-toe shoes.
Lars Bendsen: Maybe, maybe, maybe. But I’m happy. And Muehlhan is truly good people, a good company. And they have bought out, I don’t know the number of companies they have bought the last couple of years, not only in wind but also in the industrial division. They have a huge industrial company. So I think it’s something like, don’t hold me to it, 40 to 50 companies over the last couple of years. So they’re growing like crazy. And you only do that if you’re good people.
Allen Hall: That’s true. The only way to survive is with good people.
Lars Bendsen: Or people just say, “No, thank you.” Because people are not desperate to sell. And we were not desperate. We saw it as a great opportunity, and we are honored that they did it. And I think we can take the market share if we want to.
Allen Hall: I think Muehlhan, in terms of its reputation, is well known. I’ve talked to large European operators, and who do they use? Muehlhan. That’s who they use. So you hear that name pop up quite a bit, and rightly so. We’ve worked with them. Weather Guard has worked with Muehlhan in the past, and the results have been good, so we’re really grateful.
Lars Bendsen: It also looks like there will be more presence of Muehlhan, so to speak, because before it was more the individual companies that had been a part of the Muehlhan group. They’ll be branded as Muehlhan. So it’s the same companies, but there might be bigger visibility, is my guess. I don’t know, again, I’m out, I don’t know the strategy plans. But that’s my two cents, that there’s going to be a bigger visual presence as well.
Allen Hall: But in terms of contact points at AC883, Muehlhan now, you’re still able to call Jannik, you’re still able to call Jacob, Bent, and Sydney, and the whole crew is still there.
Lars Bendsen: The whole crew. No changes. Same numbers, same emails. The email signature has changed, but the same email address, same telephone number. Even I have my same phone number and my same email address. So if you’re desperate, I’m happy to pick up the phone and forward it to someone else. So it’s all in good order. I’m very happy and proud that we can do that and hand it over.
Allen Hall: Well, it’s amazing. And congratulations. But I wanted to have you back on the podcast because we’ve had you on so many times before, and because you’re such an industry insider, so to speak. You know where things happen, and why they’re happening, and the history of some of these wind events. So I use you as that resource, but you’re also a great friend, and I appreciate that. We met just randomly several years ago. Like, who is this Lars guy? And you realized immediately, super knowledgeable, smart on his feet, good salesperson, all those things you need to have in the wind industry to be successful. That’s the package.
Lars Bendsen: Well, people dealing with people.
Allen Hall: Yes. People dealing with people. Thank you so much for being on the podcast. We’re going to have to have you back on. We have to pull you out of retirement to comment on the state of the wind industry.
Lars Bendsen: Would love to do that.
Allen Hall: All right, I would love to have you back on.

Marxism
I would be shocked to learn that more than a tiny fraction of 1% of Americans voters consider themselves Marxists. The Republicans are hoping that propaganda like this will be effective, but that’s hard to imagine.
The typical progressive in the U.S. hopes to see this country refashion itself in the manner of the social democracies that are sprinkled all around the globe.

Woke Celebrity Far Out Number Trump Supporters
Glenn Close is what Donald Trump would call a “woke celebrity.” Yet what he’s deliberately ignoring is that he has virtually zero support from the entertainment industry.
Sure, you can find an occasional Clint Eastwood or James Woods. But for every one of them, you’ll find perhaps a dozen intelligent and kind people like Close who deeply resents Trump’s attempts to steal democracy from the American people and the rest of the civilized world.
I’m no expert on political demographics, but is strikes me that someone like, say Jodie Foster, who could read at age three and graduated from Yale magna cum laude, probably sees life differently from the MAGA base of carrot farmers, truck drivers, and appliance repairmen.
