Allen Hall: And welcome back to the Uptown Wind Energy Podcast.

I’m here with Rosemary Barnes, Joel Saxon, and Phil Ro. Uh, crazy week. Again, I don’t know how else to describe it. The, I was just telling our producer this morning that there’s so much news coming out where it seemed like to be a little bit of a lull after the US House bill, but it’s picked right back up again.

And one of the more exciting things that’s happened is A owns closed a $62 million series B. Uh, led by Activate Capital and S two G with, uh, revenue growing at Aeros by about 300% in 2024, and they are getting a lot of requests from [00:01:00] operators in the United States and elsewhere to fix their wind turbine blades.

They have been working pretty closely with GE Renova and NextEra. Over the last, what Joel say two years, maybe a little bit longer on a number of problems.

Joel Saxum: Yeah. A couple years they’ve been doing, uh, bespoke solutions for both of them. They’ve also been doing their, you know, standard things that they’re rolling out to the rest of the market.

But I think this is a good thing. In one article that I was reading, there is like a tier one operator starting to adopt it, right? So. Everybody was kind of approaching that robotic thing, like, yeah, it looks like it’s the future and, you know, but a little trepid, right? Dipping a toe in or dipping a finger into the water, trying it out.

But now it seems like, hey, we got an LEP campaign, coones, we’ve got this robotics problem we wanna solve, collar owns. So they’re starting to get more and more adoption and, and that shows, right, 300%, uh, revenue growth in 2024. So that’s, that’s huge, right? To, to hit that kind of number. So now it’s up to, uh, scaling up.

Uh, the only thing that can cap that number is the amount of robots that they can put outta the [00:02:00] factory over there in Riga.

Allen Hall: And we visited their facility in the United States about a year ago. It was just outside of Dallas, near Lake Dallas of all places. And it is a decent sized facility, but at the time we, when we walked around out back, you just noticed a whole bunch of, uh, parking lot spaces with trailers and capabilities for robots and thought, wow, that there’s a lot of robot, uh, sitting in the parking lot.

And, uh. But then they had, when I asked they, they said, oh, they had a ton of crews already out in the field working. So they do have the ability to get to a number of turbine sites. I, I guess maybe still not enough from what I hear, there’s, the demand has gone through the roof.

Joel Saxum: Well, it’s, it’s a really interesting, or really cool, I guess, opportunity for technicians.

So that’s one of the things that robotics does is it addresses the technician shortage. You got a technician shortage, great, let’s use robots. Then we can start, uh, having that force multiplier, right? Because you could run robots on two turbines from one control van. You can do a lot of stuff there. But as a technician, [00:03:00] what a great opportunity.

If you know blades, if you know in the field, you don’t even have to know that stuff. Not even go work with robotics and AI and like the future of cool things. And I know that a Rowan’s part of their growth and their plans here, they got the $62 million. Of course, we don’t know all the plans they are gonna do with that, but I do know that they’re making a push to hire locally to get local talent, to get local back office to expand their presence in the states.

’cause it’s a, it’s a, it’s a huge market here, right? So they’ve brought on some, some more, uh, horsepower locally from the states, whereas before they were having to bring a lot of technicians over from, from Europe. They’ve started to crack into that and use more local stuff to be able to do things faster and more efficiently, which is, uh, you know, that’s better for all the, all their customers as well.

Allen Hall: Well, I think one key about this announcement is when opportunity presented itself, I. Rowans went after it. And that opportunity was with GE Renova on some tip mast additions. And there was a lot of [00:04:00] blaze that needed some more weight in the tip, and the robot could do it faster. I think at the time, uh, GE was planning on doing it with technicians on ropes, and then, uh, aeros demonstrated they could do it faster, more consistently with robotics, and that was the opening that they needed.

I don’t remember how many, uh, blades they have done that, uh, addition to, but it’s gotta be in the thousands at this point.

Joel Saxum: I’d say this about that Arons team. I mean, you, you and I know Dyna crews very well, the CEO, we know the CTO, we know the sales team. Some of the operations people, they are not shy on grabbing an opportunity and running with it.

And, and I’ll also, this the, one of the, one of, in the, in the wind industry, one of the best companies I’ve seen. Run with primary market research, right? Where someone says, here’s a problem, can you help us solve it? Boom. They’re on it, creating a solution tomorrow. Um, and not a lot of people do that very well.

So [00:05:00] I think that’s been part of their, their prowess in, in the scale that they’ve done. And what of course, and oversubscribed funding round means you’re doing something right. And I, and I think that that shows.

Allen Hall: Over in the uk, Siemens Energy’s UK Vice President warns that allocation round seven, which is upcoming, must award a record six gigawatts of offshore wind capacity to maintain the trajectory towards the 43 to 50 gigawatt goal by 2030.

Target that the UK has set up for itself and there are, the UK is at about 15 gigawatts at the minute, and. So the, the push from Siemens is we have a factory in haul. We make blades and make turbines. We we’re really good in offshore work, but we really need to go. Uh, and that’s driven by governments putting out, uh, awards and driving the industry forward.

And, and Siemens UK vice president is saying, now’s the time. Now is a time that they really need to show progress. I think that’s [00:06:00] generally true. If you do look at, and if you, Joel, I don’t know if you saw this, or maybe Phil, you saw this this week. Uh, the UK put out a map of where all the wind farms are and where all the permanent or the rare earth magnets were located and when those farms are gonna come offline in an effort to potentially recycle those rare earth magnets.

So you have this nice little. A year by year map of the decommissioning of one cype decommission when they could reuse those rare earth magnets. And you can see all the wind farms in the uk. There are a lot of wind farms right now in, mostly on the west coast. Well, some of the west coast, a decent amount on the East coast, but there’s still a lot of onshore wind, which I didn’t realize, uh, that.

UK government effort is really paying dividends, I think, but the rate’s not enough. I guess that’s the problem. The rate is not enough to keep up where their goals are. Phil is, are they gonna be able to do that even if they [00:07:00]do have a, an allocation round of, you know, upwards of six, seven gigawatts coming up.

Phil Totaro: That’s the challenge. They have about, uh, 11,000 onshore turbines, um, in the UK at this point, according to, to our data, uh, and offshore, I forget what the turbine count is, but it, they’re, they’re up there in the, you know, 28 to 30 gigawatts now, um, that’s operational or under construction, um, which is fantastic.

You know what Siemens is saying is that. Based upon what’s happened in previous allocation rounds, um, specifically they didn’t have enough capacity to serve the entire demand. Um, basically what they were willing to allocate at, at a particular price point. Uh, and so it left the project developers and independent power producers is left with, well either, you know, we’ve gotta go find a corporate power offtake, which really for uh, [00:08:00] an offshore wind farm is gonna be much.

More challenging to do, uh, than, than onshore because of the, the size and scale of these things. Of course. Um, so, you know, they are still largely dependent on the government, you know, facilitating this offtake through, you know, national Grid and, and the other grid operators to be able to have. That allocation of power and then, you know, more utility contracts get signed, um, that way.

And, and that’s how people get fed. How

Joel Saxum: many years, Phil, did they have that? Uh, like on there was an onshore moratorium against more new onshore wind. How many years did that last?

Phil Totaro: I wanna say it was like eight. Uh, if memory serves to, just to clarify this, so the head of moratorium in Lower England, which is basically, you know, not Wales, not Scotland, not Northern Ireland or, uh, you know, any of the outer banks areas.

Um, but just lower [00:09:00] England, they’ve removed that. At least in principle. And so far there’s only been one proposed project from Kubico, uh, that was actually had been proposed from like, whatever, 15, 20 years ago. And now they’re like, Hey, great, we can actually do our project now. Uh, you know, like everybody’s just kind of waiting for whatever the mechanism is gonna be.

Um, and where the demand is is gonna come from the, you know, everybody keeps talking about things like AI and data centers and. Et cetera. And, and yet their, their pipeline for project proposals in, uh, you know, the lower England, again, so to speak, is, is, uh, a little bit thin by comparison. They’re really trying to focus more on offshore wind for.

You know, power that’s gonna be fed into London and the surrounding areas. And Scotland is still going strong with, uh, you know, with onshore wind and of course whatever, whatever offshore they’ve got up there. Um, [00:10:00] but they’re building a lot of interconnectors as well with Ireland, with France, um, and I think one with Norway, if memory serves or is it Denmark?

One of those. Um, but they’re, they’ve got, you know, power links going all over the place now to be able to, to, you know, feed and balance power with Europe.

Joel Saxum: Yeah, I think the, I think the interesting thing here is, um, I mean, from Siemens energy point of view and from, I mean, you name it, if it’s Vestas or GE or whoever of their offshore wind needs some wins.

Uh, no pun, no pun intended. Like, we, we need some good news. We need one of these auctions to go well as a, as a group. Um, just to reinstall confidence that offshore wind is the, the way of the future, right? So we have some movements, right? You’ve seen Japan open up their EEZ, that’s fantastic. Um, we saw some of the projects in the states get moving again, great news.

Um, but you see still this kind of lukewarm temperature towards offshore wind. So it would be great to [00:11:00] see this thing go fantastically so that, uh, we get. Kind of the, the winds back in our sails pushing

Allen Hall: offshore wind forward. We’re gonna take a quick break here, but when we come back, we’re gonna talk about Canada getting into offshore wind and what that means as wind energy professionals staying informed is crucial.

And let’s face it difficult. I. That’s why the Uptime podcast recommends PES Wind Magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future. Whether you’re an industry veteran or new to wind, PES Wind has the high quality content you need.

Don’t miss out. Visit p ps win.com today. Well, up in Canada, Canada’s uh, bill. 49 C 49, uh, establishes a joint federal provincial management of offshore renewable energy development with Newfoundland and Labrador, uh, targeting up to $1 trillion in renewable energy investment by [00:12:00] 2041. Trillion’s a big number, Joel.

Uh, the, the regulatory framework addresses jurisdictional complexities that have historically complicated offshore development and is creating some streamlined programing. Permitting that, uh, mirror successful offshore, uh, petroleum models. Now, I, this is really Canada taking advantage of what has happened off the east coast of the United States in that, uh, if progress is gonna slow off the Atlantic, then Massachusetts, New York, New Hampshire, Maine, all those East coast states can be fed and are currently fed.

Um, by Hydro Quebec and others, uh, to provide power. So if they, if Canada does decide to build offshore wind up in Newfoundland, it’s pretty easy to get the power to Canada and to the United States. That could be a huge win. And the cost of doing business in Canada is lower than it is in the United States at the moment.

Joel Saxum: There’s a fundamental trouble there. So, Newfoundland Labrador, [00:13:00] amazing wind resources, like I’ve spent some time up there, right. Um. The other side of it is, uh, about 90, I think it’s like, it’s really high. It’s like 98% of their power is renewable already. It’s, they have a lot of hydro, they have a ton of hydro resources and a lack of, uh, heavy industry or load.

Right. So it’s not, if you look at the population of Newfoundland, like most of it’s in St. John’s Labrador. Labrador City Lab City’s got some population, but the population of those two areas, and I I, the island of Newfoundland and Labrador mainland is so small that there’s not that much demand. Right. I think they’re total, I can’t even say what their total numbers are, but I know they’re low.

Right. And there’s not a lot of heavy industry there. There’s not a lot of things there that are going to take advantage of this wind resource they have. So you’re either gonna be looking at green hydrogen of some sort. Or you’re gonna be exporting. So whether you’re exporting back to the [00:14:00] mainland or you’re HVDC exporting down to the states, and that’s the route I would go simply because even when you start passing back to the mainland, so you’re gonna New Brunswick and that, like, there’s no load there either.

Like there’s no load until you hit Halifax. Right? So there’s, there’s just a lack of, there’s there, they have the abundance of wind resource and a lack of off take. So. Put it in a cable and ship it down to the states where we need it anyways. And, uh, triage it that way, that’s the way I would look at it.

I’m, I’m super happy up for, for them.

Rosemary Barnes: But Quebec’s already connected to the US right? They’re, yeah. So if they are, their grids already very renewable, but it’s hydro, which is dispatchable. And so if they can replace more of their own, um, you know, local generation, even if they can’t connect all of that, um, you know, new, the new projects, if they can’t get capacity to connect it all to the us you know, directly, they could at least reduce the amount of their hydro that they have to use [00:15:00] themselves and then allow them to sell it to the US when, um, yeah, when prices are high.

So it seems like it would still be, still be a win. And it also seems like it would be a whole lot easier to develop those wind farms than to go slightly south and you know, the troubles that the US is having developing. Developing those regions for offshore wind seems like this would be an easier solution.

I don’t see a whole lot of like the, you know, the northeast of the us. So many people live there and they just seem like really set on categorically eliminating every single, um, sensible idea that they could have for. Generating electricity into the future and not just assuming that they want to decarbonize, even forgetting about that, they’re still, like, they, they won’t, they, they won’t build anything basically.

Every, you know, you can’t, um, take advantage of the inland wind. They don’t want more nuclear. They don’t want more gas. They don’t want, uh, yeah, the, the, they don’t want offshore wind. [00:16:00] I, I don’t know. There’s, there’s a finite number of options that you can. That you can choose from to, um, figure out your new, you know, what your future electricity mix is gonna be.

Um, it seems like it might be easier to, uh, you know, build a project in Canada, but they don’t seem so, so, uh, you know, bothered by every single option that you could come up with to generate electricity. They seem quite happy to, you know, generate cheap green energy and, um, sell it at a premium to the us so.

Maybe that’s a, a win-win for everybody. I mean, it’s a, it’s a win-win except for in probably the, the cost of electricity that, um, you’ll pay in, in New York, obviously it would be cheaper to just directly build the offshore wind and connect it right into the grid there, rather than having to go across the border via HVDC, but

Allen Hall: I don’t know.

I, I, yeah, I’m really wondering about the economics of that Rosemary. Just because things are cheaper in Canada. Well, yeah, it was about 30% less than what it costs in America to do things. [00:17:00] So just during that 30% number, if you could install wind at a 30% lower cost, you could then spend some money on building a cable or two.

To me, that’s, that would, it would start to pencil out. You have to start thinking. America’s not gonna move. They’re

Joel Saxum: attached to Canada permanently. One, one of the things that we’ve said that there’s an issue with the United States, okay, we talked Jones Act and Vessels and these kind of things, but one of the, you know, the crux of the Jones Act is people and the fact that along that, like East Coast of the United States, while it is a maritime or a marine environment, it is not a maritime society, right?

You don’t hit. A lot of big ocean going like, like when you’re in Denmark, a lot of people have worked on boats. They’ve worked offshore, they’ve done these things. You don’t run into that along the East Coast of the United States. However, when you go to PEI and Cape Breton and Nova Scotia and Newfoundland, PE, like those people, they’ve.

They’ve lived with the [00:18:00] ocean, right? That’s, that’s their bread and butter. They’ve been on fishing boats. They know there’s a lot of mariners up there. So I think that if you’re looking for the ability to ramp up and scale up a, uh, a workforce, it might be easier to do it there as well. So there’s some advantages to doing things in Canada.

Allen Hall: Do you think that, uh, they’ll find. Operators willing to take that risk or who have put down deposits on turbines that they can’t put into the United States that’ll just say, Hey, we can move up to Canada and do it there.

Joel Saxum: Well, I think there’s, there’s a couple of trouble troubling things there. If you wanna operate in Newfoundland Labrador, offshore wind, you better have your wits about you when it comes to o and m, ’cause that is an unforgiving environment.

I mean, you’re literally, you’re combating, uh, icebergs, right? The Titanic sunk off the coast of Newfoundland. So just so we’re all clear that their icebergs are a real thing up there. Really nasty. You’re in the North Atlantic now. You’re, you’re not in Kansas anymore, right? It’s, it’s [00:19:00] nasty up there. It ain’t Australia, I’ll tell you that.

So making sure that you, you’ve got your o and m budget squared away and everything is great. The other, the other economic thing. I don’t know what kind of, now they’ve said they’ve streamlined some permitting and some other things here in this bill that Canada put up. Great. To export renewable energy from Canada to Mexico or to Mexico, from Canada to the United States.

You got, you got to have your, the, the, uh, economics. Correct. Because one of the things we always talk about in the o and m world is how much better the PPAs are in Canada. Right where you’re gonna see, you’re gonna see in Michigan a 60, $70 PPA, you go across the border in Canada and that is a a hundred dollars PPA or $110 PPA.

Right. So if you have a hundred, if you can, if you can build a, yeah, if you can build a wind farm, and, and I’m, I’m just looking at the map right now, I’m going clo a little bit closer. If you can build a wind, wind farm off shore in Nova Scotia, which is a couple hundred miles from Maine. Right. Not a big deal.[00:20:00]

You better hope that you can get more for that power coming into the United States than Nova Scotia would allow you in an offtake PPA agreement, because you’re gonna have to beat that to send it elsewhere.

Rosemary Barnes: But did you know that there’s a plan to connect the um, yeah, connect Canada? I, I think connect Labrador.

It might be from somewhere in that region anyway, to the, to the UK to. Island, maybe

Joel Saxum: that, I mean, that makes sense.

Rosemary Barnes: Yeah. I mean it’s long, I think it’s four or 5,000 kilometers, um, cable, something like that. Um, may maybe it goes ahead. Maybe it doesn’t. It, yeah. It, it’s long, it’s unprecedented. There’s a whole lot of technical challenges to solve, and I.

But you know, like as far as some of these, uh, really big interconnections, I mean, there’s always a political challenge that, you know, I just mentioned between, um, Canada and the US Probably wasn’t the slam dunk that you would’ve thought it was a couple of months ago. But some of the other big ones that are planned, like from Australia, they plan to connect the north of Australia to Singapore via Indonesia.

I mean, we’re not countries that are, you know, extremely, uh, close [00:21:00]on our, um, you know, international relations. Then the other big one is X links between Morocco and the uk. And again, like these aren’t countries that we’re not like at war or anything, or worried about imminent war. I mean, we’re, we’re friendly but not extremely like-minded.

You know, between, um, Ireland and, uh, and Canada. I mean, that’s, as you know, that, that’s more closely aligned in terms of, you know, culture and, uh, history than any of those other pairings. So I do think it has that benefit.

Phil Totaro: The challenge with this is that we actually ended up canceling a lot of the grant money for some of those HVDC lines we were gonna put.

To expand the capacity between the US and Quebec. Uh, so they’re gonna build, you know, additional pipeline there to be able to, to offtake some of that power. But we’re not gonna be able to accept it if we don’t have the matching HBDC [00:22:00] capacity to be able to offtake the power down here. So that’s still a technical challenge to be overcome potentially in another three and a half years.

Allen Hall: When we come back from the break, we’ll talk about vest’s newest. Onshore turbine, a masses 7.2 megawatt machine. Don’t let blade damage catch you off guard. OGs. Ping sensors detect issues before they become expensive, time consuming problems from ice buildup and lightning strikes to pitch misalignment and internal blade cracks.

OGs Ping has you covered. Their cutting edge sensors are easy to install, giving you the power to stop damage before it’s too late. Visit eLog ping.com and take control of your turbine’s health today. Well, Vestas has achieved its first commercial installation of its V 1 72, 7 0.2 megawatt turbine in Germany.

Joel, this is awesome. Which marks the latest evolution of, uh, the Inventus platform. They’re looking towards medium and low wind sites, [00:23:00]which I think makes a ton of sense.

But they’re also, uh, I think the hub height’s like 175 meters because they’re having issues in Europe. Right, right. It’s 175 meters. Uh, but the rotor, Joel is 172. Right. So. The rotor diameter and the hub height, you know, it’s, it’s, they’re approaching one another. Uh, 7.2 would be a big term in the United States.

GE is only offering what a 6.1 at the moment is kind of where they stopped. This one makes sense

Joel Saxum: that they’re putting it in Germany though, because Germany classically, right, they’re a little bit more land constrained for turbine locations, right. It’s not like the United States where you drive across Iowa and you’re just like, boom, boom.

There’s a hundred turbines there and a hundred turbines there. Um, they’ve gotta pay a little bit more attention to, they’ve got a lot of little smaller towns in places and different local laws. Uh, so you’d see smaller, I imp smaller wind farms. And I think what you’ll start to see here is, is [00:24:00] as those wind farms have that interconnect and they’re good to go, but they’re getting aged out, you’ll see one of these turbines replace, you know, 2, 3, 4 of the old ones.

Uh, is, is what I could see in some of those European. Places as well.

Allen Hall: Is there a broader market for a seven megawatt machine? I think so. Um, I guess I’m asking is there’s a lot of low wind areas that tends to be what’s left. All the prime locations with medium high wind are already taking. So if you want to hit somewhere and put a lot of turbines up, you have to be low to medium.

Speed is, it’s a question of the hub height. The 175 meter hub height is. Big.

Phil Totaro: Yeah. And the, the challenge with that is that, uh, I think Rosie mentioned it last week or two weeks ago, about when people build wind farms, they interconnect them to the closest, uh, available transmission. Certainly, you know, that’s what they’ve done in Australia.

That’s what we did in the United States as well. Um, and. [00:25:00] You’re necessarily going to build out everything you can in what we used to call kind of IEC class one winds. That’s the highest, you know, average wind speed about 10 meters a second. Once you’ve kind of fully penetrated those sites that are in close proximity to transmission, you start stepping down, you know, your average wind speed, and then that’s why you need to increase the, the power density.

And basically for a given, you know, nameplate capacity of the turbine, you’re, you’re making a bigger and bigger rotor all the time and a higher and higher hub height. Um, so where is the market for this besides, you know, Scandinavia and Germany and a few places in eastern Europe? Australia is the big market.

Chile, Argentina. If Brazil decides to come back as a market, that will be a market for these as well. Um, it’s basically places where they still have wide open country and they’re not gonna be land constrained. Now, theoretically, in the United States, we’re not land constrained, but. We, uh, you know, you’re only gonna [00:26:00] be able to put these in specific places where you don’t have FAA interference or, you know, you, a lot of counties and townships now have, you know, tip clearances from, you know, adjacent dwellings that are gonna preclude you from using anything this big in this market.

It’s one of the challenges that a company like Weg, who also has a seven megawatt turbine, they’re trying to sell it in the United States and, you know, it hasn’t been, unfortunately for them going. Uh, very fast because there’s only a handful of sites where they can kind of put that thing and, and repower those, um, you know, these type of smaller projects with something this, you know, this massive.

Rosemary Barnes: Yeah. And I think that equation is changing a bit recently. Like, um, like you said, you know, you start out in high wind speed sites that are near transmission and then kind of go down. I think what counts as near transmission is sort of. Changing because it’s harder. I think everybody around the world is finding it hard to build out even small bits of new transmission that they [00:27:00] need now compared to what we thought that it would be like a few years ago.

So I know in Australia our grid operator is explicitly, um, trying to move away from having to rely on that. So that means, yeah, building out more renewables in or close to urban areas. And, um, yeah, part of that, especially for wind, is gonna mean accepting a, a lower quality resource, which is, you know, the cost of energy from the, a lower, a lower speed wind site is gonna be higher than an equivalent, you know, higher speed one.

Um, Australia is definitely, like, when I talk to developers, onshore developers, they definitely are largely thinking bigger, bigger, bigger turbines for onshore still. So there’s an appetite for it. Um, I do question, you know, to what extent it makes sense.

Allen Hall: And the question I always have is, how many turbines do you have to sell early on to make the project profitable?

Rosemary Barnes: Oh, I don’t think the early sales are [00:28:00] gonna make it profitable or not, but, um, definitely most of the. OEMs like to have a large initial customer or a few before they start developing something.

Something that’s quite new. Unless they’re, you know, like really certain that it’s gonna be their new workhorse platform. Um, you know, if it’s a bit niche, they definitely want some, um, advanced sales to cover the cost of development. At the very least.

Joel Saxum: I think, I think Phil, one time, a long time ago you said it would be roughly cost like a billion dollars when you go from a brand new turbine model.

Now this is Inventus platform, so this platform has been done before.

Phil Totaro: That was for offshore. We, we have run numbers in the past on, um, exactly this kind of profitability question, like how many units do you have to produce of each make and model for the OEMs, which is actually why when, when Siemens Gmaa merged, their numbers looked so.

Weird that we were like, this can’t be true. But it’s exactly predicted [00:29:00]why they ran into the profitability problems that they did even prior to trying to sell the, the four megawatt platform. Um, we kind of held back from publicly announcing that because we thought we were wrong and I should have, you know, insisted that we do it because it, it would’ve really shed a lot of light on, on what was really going on over there.

But anyway, in the meantime, it’s, it’s roughly for like a. Two to 2.53 megawatt turbine. It was about 350 units as you go scale up nameplate capacity, it starts coming down. Um. You know, in, in the number of units you need to sell, but it’s still roughly around, um, let’s say, you know, six to 800 megawatts worth of capacity needs to be sold just to break even.

Um, and that’s assuming, ’cause again, back in the day when we did the calculation, they were still having like a 12% margin. They’re not getting that anymore. It’s maybe like two to 5% now. So let’s say conservatively, it’s probably [00:30:00] about 1.2 gigawatts worth of capacity needs to be sold for them to just.

Break even. And, uh, you need, you know, really to turn a, a serious profit to get, you know, executives interested. Probably about two gigawatts worth of sales. So this week’s Wind Farm of the Week is

Joel Saxum: the Coyote Wind Farm. This is an EDF Wind Farm in Scurry County, Texas. So it’s 243 megawatts. And we’re, we’re switching gears and gonna talk about the SGRE.

4.5 megawatt, 1 45 turbine. On this one there’s 59 turbines. So they’re big turbines, right? Big turbines in the United States. More power with less footprint. An interesting thing here is, uh, at the time this thing was put in, that was some of the first, uh, installations of the SGRE 1 45. Uh, in the states and Masar, uh, owns 50% of this thing with, uh, EDF.

So you have 50% EDF, 50% masar. EDF runs the wind farm of course, for them. Uh, but Masar money coming from overseas, coming from the Middle East. Um, so, and that was [00:31:00] one of their first to four raise into the United States as well. Um, this wind farm can generate, uh, enough power to sufficiently supply about 65,000 households, which is really interesting.

Uh, and again, we always wanna focus on community engagement. Here we’re talking Wind Farm of the Week. Uh, what they did when they built this wind farm, uh, was to make sure that they engage with the local stakeholders they had meeting after meeting, after meeting edfs and the team out there, uh, talking with the locals, and they got, uh, everybody to buy into this one locally.

And there’s a really cool, and what I wanna focus on here is there’s a really cool, uh, YouTube video. So if you’re on YouTube, uh, spending some time at work or, or at home. Uh, just look at the Coyote Wind Project, uh, from EDF and they have a video there about how they showcase this thing locally, uh, and how they work with the local government.

So the Wind Farm of the week this week is the Coyote Wind Farm from EDF.

Allen Hall: Thanks for that Joel and Rosemary, Phil and Joel and I, we’ll be back next week from the Uptime Wind Energy Podcast. [00:32:00] Everybody keep their heads up. There’s a lot happening in wind at the moment. Uh, it’s gonna change, it’s gonna get better.

We just need to focus on profitability. That’s what we really need to do right now. And I, I, I get everybody is frustrated and they should be, uh, but not everything’s locked in, in the United States. Things are headed. At least it smells like things gonna be headed in a little bit of a better space over the next couple of weeks.

So let’s see what happens and we’ll see you here. Next week on the Uptime Wind Energy Podcast.

North Carolina needs more certainty before committing to an expensive new gas plant

Published

on

Despite massive uncertainty across the economy, Duke Energy is plowing ahead with its plan to build new fossil gas-fired power plants to serve data center, manufacturing, and other large customer load that may not even show up. Duke has asked the NC Utilities Commission for permission to build a combined-cycle (CC) gas plant in Person County, North Carolina, at the site of Duke’s Roxboro coal plant.

SACE has argued against the need for this gas power plant in the Certificate of Public Need and Necessity (CPCN) docket, submitting testimony to the Commission on Monday, June 9, 2025. Here’s a summary of that testimony (prepared by Synapse Energy Economics, Inc.), which explains what this all means for Duke’s billpayers, and how Duke can make changes within its control to protect customers and reduce pollution. These recommendations include:

  • Not approving this new gas power plant because the risks that it will increase bills are too high. Instead, Duke should improve the processes that are holding back lower-cost renewables and storage, then use renewables and storage to meet new load.
  • Instead of approving this specific gas plant, the Commission should order Duke to use an all-source procurement process to determine a portfolio of flexible assets that can meet the utility’s needs based on real-world costs.
  • In the event the Commission approves this gas plant, it should protect customers from high bills due to volatile gas prices by instituting a fuel cost sharing mechanism for the fuel costs spent to run this plant.

Duke Doesn’t Need this Risky Gas Power Plant

Duke’s claim that it needs this fossil gas power plant is based on outdated analysis. In this CPCN docket, Duke relies on its 2023 Carbon Plan Integrated Resource Plan (CPIRP) modeling and the CPIRP supplemental update and analysis filed in January 2024. The world has changed dramatically since then, and it is important that the Commission review the latest information before approving expenditures that will impact customer bills for decades.

Duke’s load forecast – once based on steady, predictable growth – is now subject to significant uncertainty as 1) data center developers look around the country for the best deal and the fastest interconnection to the grid and 2) manufacturers announce projects and then pull back as political uncertainty changes the economics of those projects. Under Duke’s current rate structure, prospective companies and site developers do not need to commit much money to become part of Duke’s load forecast. They have very little “skin in the game,” and Duke currently does not have policies in place to change this. If the Commission allows Duke to build an expensive fossil gas plant for load that doesn’t materialize, Duke’s remaining customers will be on the hook to pay for it.

Duke’s own load forecast updates since 2023 show that there are wild swings in its predictions. In the Spring of 2023, Duke anticipated 8 new large load projects during its 10-year planning forecast period, requiring an average of 169 MW each. Then for Fall 2023 (the supplemental update filed in January 2024), Duke anticipated 35 projects requiring an average of 111 MW each. In Summer 2024, Duke changed its forecast again, projecting 39 projects requiring an average of only 103 MW. And in May 2025, Duke filed an update showing a reduction in the number of projects back down to 35 but a dramatic increase in average need – back up to 169 MW. Duke’s forecasts will continue to show swings up and down – both in the number of projects and megawatts – until Duke has policies in place that require more commitment from the companies that knock on its door requesting service. Duke also has not published information regarding the location of these loads – the latest forecast applies to all of Duke Energy in both North and South Carolina.

It is also important to know that that this gas plant isn’t needed to meet growing load from existing customers or to replace retiring coal plants (according to Duke’s own testimony). This gas plant is being justified by new manufacturing and data centers claiming they will be operating somewhere in Duke Energy Progress or Duke Energy Carolinas territory in North or South Carolina.

Even if the load shows up, this plant won’t be needed for long

Even Duke admits that it doesn’t “need” this fossil gas power plant for very long. These kinds of power plants, combined-cycle plants, are typically used about 80% of the time, i.e. they are “baseload” power plants. But even absent federal carbon regulations, Duke expects this power plant’s usage to decline significantly throughout its 35-year lifetime (from 80% in 2030 decreasing to 46% by 2040 and only 13% by 2050 onwards). As cheaper renewables and storage with zero fuel costs are brought online, they will displace this plant. Duke is proposing to build a giant power plant that will very quickly run less and less – but Duke’s customers will continue to pay for it until 2065—15 years past a state law requiring Duke’s generation fleet to be carbon neutral. This represents a significant change in how power plants are built and run, and this is not in the best interest of Duke’s billpayers. To add insult to injury, Duke hasn’t even procured all of the equipment needed to build this plant, so the costs could skyrocket even more than they already have since last year’s carbon plan proceeding.

Renewables are flexible, would protect customers, and would reduce pollution

Duke’s model only chose a gas plant to meet this capacity need because of limits Duke imposed on the model. Duke claims it cannot interconnect renewables and storage fast enough to meet this capacity need, but the reasons it cannot interconnect those resources faster are all within Duke’s control. As Synapse recommends, Duke needs to update its processes that are holding back renewables and storage from serving customers with low-cost and low-risk resources. These processes include interconnection and transmission planning.

SACE has been advocating for improvements to these processes for years, and Duke has made changes to both its interconnection process and transmission planning. Duke was one of the first utilities in the Southeast to implement cluster studies in its interconnection process, and it is in the midst of the first scenario-based transmission planning exercise in the region. But is there evidence that these updates have helped if Duke continues to limit solar and storage in its future resource modeling? Given the much quicker interconnection process recently demonstrated in Texas, this raises the question of how hard Duke is really trying to streamline renewables interconnection.

Modular, flexible resources such as wind, solar, and energy storage can be adjusted in quantity based on market conditions. As our testimony from Synapse states, “This modularity, combined with the fact that solar and wind have zero exposure to fuel price volatility once they are constructed, makes these resources particularly valuable in the face of trade tariff uncertainty.”

The bottom line is that the Commission needs a lot more certainty about load growth and costs before committing Duke’s billpayers to any type of large fossil gas power plant. We simply do not have that now.

Ultimate Guide To Understanding Every Type Of Solar Panel

Published

on

Are you thinking of switching to solar but feeling overwhelmed by the wide range of panel options available in the market? 

You’re not alone, as many others feel the same way. 

In a sun-drenched country like Australia, where electricity prices seem to climb every year, more households are turning to solar as a smart, sustainable solution.  

The reason for this energy transition is apparent: harnessing clean, renewable energy gives you energy freedom, saves you costs on electricity bills, and reduces your reliance on fossil fuels, lowering your carbon footprint.   

Moreover, solar panels are not only good for the planet; they’re an investment for your future!  

But with so many types of solar panels, how do you know which one is right for you? 

  • Which panels perform best in Australia’s diverse climate?
  • What type suits your roof, your budget, and your energy needs?
  • And most importantly, are they really worth the cost? 

Well, in this comprehensive guide, we’ll explain the above questions and everything you need to know about solar panels in Australia.  

From solar panel types to benefits and efficiencies, this ultimate guide on all types of solar panels in Australia will help you find the most suitable panels for your home and financial needs. 

So, tag along to learn more details!  

What Are Solar Panels? | Breaking Down the Power of the Sun!

Let’s begin by addressing a very basic question: What is a solar panel, and how does it work? 

A solar panel is a device that converts sunlight into electricity using photovoltaic (PV) cells. Instead of burning fossil fuel, these different types of solar panels generate clean, renewable energy with Australia’s abundant sunlight.

How Solar Panels Work: A Simple Breakdown!

At the core of every solar panel, there is a set of photovoltaic (PV) cells. These cells are responsible for converting sunlight into usable electricity.  

When sunlight hits these cells, it excites electrons within the silicon-based material, creating an electric current. This current is then captured and converted into alternating current (AC) through an inverter, making it suitable for household or commercial use.  

However, solar panels cannot store energy for later use. Therefore, you might need to add battery storage to keep your home illuminated at night or during low-light hours. 

Are They Worth It for Australians?

Solar panels are generally a smart investment for most Australians due to the country’s high solar exposure, government incentives, and rising electricity costs.  

With abundant sunshine, households in most Australian cities can generate a significant portion of their electricity needs from solar. This energy switch can be a significant key to reducing power bills while enhancing grid stability. 

For example,  a 6.6 kW solar system can save households $1,000–$2,500 per year, depending on usage and feed-in tariffs. They can reduce your power bills by up to 70% 

Moreover, the federal Small-scale Renewable Energy Scheme (SRES), energy-saving schemes and various state rebates and incentives significantly reduce the upfront cost of solar systems.

So, with all these long-term savings, generous incentives, and positive environmental impact, solar panels offer a sustainable solution, making them a worthwhile financial and environmental investment for all.  

What Are the Most Popular Types of Solar Panels Available in Australia?

types of solar panels

Australia’s strong solar market offers various solar panel options tailored to different needs, budgets, and property types. Homeowners can access high-quality solar technologies from both local and international manufacturers, creating a global bond.  

However, instead of making a blind choice, it’s wise to understand the different types of panels, as each has different efficiency, durability, and cost advantages.  

So, before moving further, let’s have a glimpse at the most popular types of solar panels currently available in Australia:  

Monocrystalline Solar Panels: Premium Efficiency and Longevity

Monocrystalline solar panels are the most efficient type of solar panel. They are made from a single, pure crystal structure, which allows electrons to move more freely, resulting in higher efficiency.   

These panels are easily recognizable by their dark black color and rounded edges. While they are more than other types, their high efficiency and longevity make them a great investment. 

What are the Pros? 

  • High performance in low-light and high-temperature conditions. 
  • Sleek, modern look. 
  • Lower long-term cost per watt. 
  • Best for homeowners with limited roof space.  
  • Incredible longevity and efficiency.  

Talking about Cons: 

  • Monocrystalline panels are expensive. 
  • The manufacturing process results in silicon waste. 

Polycrystalline Solar Panels: Reliable and Cost-Effective

Polycrystalline solar panels are made from multiple crystal structures, which gives them a blue hue with a speckled look.  

They are less efficient than monocrystalline panels but are also less expensive. These panels are great for those with ample roof space and a tighter budget.  

What are the Pros? 

  • More affordable than Monocrystalline panels. 
  • Leaves less waste during production. 
  • Offer decent performance for residential use. 
  • Easier manufacturing process.

Talking about Cons: 

  • Less efficient. 
  • Require more space than Monocrystalline panels. 
  • Lower the aesthetic appeal of homes. 

Thin-Film Solar Panels: Lightweight and Versatile

Thin-film solar panels are the most affordable but least efficient type, with energy efficiency ranging from 7% to 18%. They are made by layering photovoltaic materials onto a surface.  

These panels are flexible, lightweight, and ideal for industrial and commercial use in Australian landscapes. 

The types include: 

  • Cadmium Telluride (CdTe) Panels 

Cadmium telluride is the most common thin-film panel, constituting about 5% of solar panel sales. These panels can achieve an efficiency rating of 9% to 15%. 

They are made from cheaper, toxic materials such as cadmium telluride and cadmium sulphide, which can pose environmental and health risks. 

  • Amorphous Silicon (A-Si) Panels 

Amorphous silicon panels use a different technology that makes them very flexible. Instead of using crystalline silicon wafers, these panels use a thin silicon strip with a rubber-like texture. 

These panels are incredibly lightweight, versatile, non-toxic, and cheap, but have a low efficiency rating of about 7%. 

  • Copper Indium Gallium Selenide (CIGS) Panels 

CIGS panels are the most efficient thin-film panels available. They are composed of copper, gallium, indium, and selenide layers placed on a base of steel, glass, plastic, and other materials. 

These panels can be installed where standard panels cannot fit. They have a high enough efficiency rating of 12% to 15%.  

Bifacial Solar Panel: Power from Every Angle!

Bifacial solar panels can generate power from both sides, capturing sunlight that hits the front of the panel and light that reflects onto the back. It’s like double the sides, double the Power! 

This can increase energy production by up to 30%. They are ideal for ground-mounted solar systems or buildings with reflective roofing.  

Concentrated PV Cell (CVP)

Concentrated PV cells are the most efficient type of solar panel available today. They use lenses or curved mirrors to focus sunlight onto a small area of high-efficiency solar cells.   

However, they require direct sunlight and a cooling system to function effectively. They are more suitable for large-scale commercial projects in sunny locations.   

Solar Panel Types by Efficiency and Longevity: A Detailed Comparison

Type Efficiency Lifespan Perfect for
Monocrystalline 18–22% 25+ years Homeowners with limited roof space or those prioritizing efficiency and longevity.
Polycrystalline 15–17% 20–25 years Budget-conscious users with ample roof space.
Thin-Film 10–13% 10–20 years Large buildings, factories, and unconventional surfaces like car roofs or windows.

5 Factors to Look for While Installing a Solar Panel in Australia

Choosing the right panel is just half the job, where installation quality and system design play a huge role in overall performance. 

So, here we’ve listed what to consider before installing a solar panel on your property:

1. Sun Exposure and Roof Orientation

Proper sun exposure is a significant factor for maximizing energy production. In Australia, a north-facing roof typically captures the most sunlight.  

Also, ensure your roof is free of large trees, chimneys, or other shading.

2. Solar Panel Efficiency

Higher solar panel efficiency means more power, which ultimately leads to faster return on investment (ROI). This is especially important if your roof area is limited or you live in a rented property.

3. Durability and Warranty

Look for panels that offer 25-year performance warranties and 10–15-year product warranties.  

These warranties can provide long-term peace of mind and potentially save you significant repair or replacement costs.  

4. Installer Credentials

Once you decide to install solar, choose Clean Energy Council (CEC) accredited installers.  

They’ll help make sure your system follows Australian rules and let you know about rebate eligibility criteria.  

5. Proper Installation and Aftercare

Lastly, the installer will mount the solar panels on your roof and connect them to a solar inverter.  

After the installation, the system will need to be inspected by a certified electrician. Then, a monitoring app will track how much electricity your system produces and how much you use.

Some Other Hidden Factors That Might Impact Your Solar Setup!

While planning a solar installation, most people focus on the obvious elements like panel type, system size, and cost.  

However, beyond these core considerations, there are several lesser-known factors that can quietly influence the efficiency, longevity, and overall success of your solar setup.   

This includes: 

  • Hail Rating of the Panel 

This rating indicates how well solar panels can withstand hail impacts. Panels are typically tested by firing ice balls at them to simulate hail.  

A higher hail rating means better durability in hail-prone areas, reducing the risk of cracks and performance loss. Crystalline panels can handle hail hitting speeds up to 50 mph, while thin-film panels are thinner and less resistant. 

  • Temperature Tolerance of the Panel 

Solar panels become less efficient at high temperatures. Temperature tolerance, often measured as a temperature coefficient, tells you how much performance drops per degree above 25°C.  

Lower coefficients mean better performance in hot climates. So, here are the temperature coefficients for different panel types: 

    • Monocrystalline: -0.3% to -0.4% / °C  
    • Polycrystalline:  -0.4% to -0.5% / °C 
    • Thin-film: -0.2% to -0.3% / °C 
  • Fire Rating of the Solar Panel 

Solar panels and mounting systems must meet fire safety standards. The fire rating is usually classified in Class A, B, or C, reflecting the system’s resistance to fire spread and ignition.  

Class A is the most fire-resistant, which is crucial in wildfire-prone regions like Australia. 

  • Light-Induced Degradation (LID) 

LID (Light-Induced Degradation) is a common issue in crystalline solar panels, where they lose about 1–3% of their performance during the first few hours or days of sun exposure.  

It happens when sunlight reacts with tiny amounts of oxygen left in the silicon during manufacturing.  

This reaction slightly disrupts the silicon structure, reducing the panel’s efficiency. 

How to Choose the Right Solar Panels for Your Property?

Every home has different setups, so the solar panel installation process also varies from home to home. Here’s a stepwise checklist to help tailor the perfect setup: 

Step 1: Assess Your Energy Needs 

Before choosing solar panels, look at how much electricity your home uses. Check your electricity bills to calculate your average daily usage in kWh 

If you’re planning to expand or add things like an electric vehicle or a home addition, consider how that might increase your energy needs in the future. 

Step 2: Evaluate Roof Size and Position 

In Australia, your roof’s position and condition matter greatly for solar energy generation. Therefore, while installing the panel, you should consider: 

  • Roof orientation, as south-facing roofs typically capture the most sunlight.
  • Proper tilt and shading for minimal shading from trees, chimneys, or nearby buildings.
  • Larger roofs offer more installation space, while older roofs may need repairs, so check the roof size and condition first. 

However, if you have limited space, go for high-efficiency monocrystalline panels, and Polycrystalline might be a better value for plenty of space. 

Step 3: Set a Budget 

Solar Power System prices vary widely from place to place. But with our 440W Tier-1 Panels and 5kW Wi-Fi Inverter in a 6.6kW Solar Power System, you can enjoy the benefits of solar power without a hefty price tag. 

  • For 6.6 kW System: 

Original Price starts from $3,690.00 

Cyanergy’s VIC Offer Price starts from $890.00 

  • For 10.12kW System 

Original Price starts from $5,770.00 

Cyanergy’s VIC Offer Price starts from $2,970.00 

  • For 13kW System 

Original Price starts from $7,130.00 

Cyanergy’s VIC Offer Price starts from $4,330.00

Step 4: Find a Trustworthy Installer & Factor in Rebates 

Federal STC rebates and various state-based incentives can save you thousands off your upfront cost, so look for a certified, experienced installer who can help you claim them.

So, Which Solar Panel Type Should You Use?

Honestly, there is no specific answer to this question. The panel type and effectiveness depend on several factors, including your installation location, budget, and aesthetic preferences.  

However, here we’ve shared a quick guide based on different situations to make your purchase decision easier:  

Different Scenarios Recommended Type
Limited roof space or rental property Monocrystalline
Tight budget with big roof space Polycrystalline
Flexible portable solutions Thin film
Need long-term high output Monocrystalline
Off-grid or rural installations Thin-Film or Hybrid

Wind Turbine Monitoring: Fibersail’s Predictive Maintenance Could Save Operators Billions

Wind Turbine Monitoring: Fibersail’s Predictive Maintenance Could Save Operators Billions

Wind turbine blade failures represent the largest ongoing expenditures facing wind energy operators, with over $5-6 billion spent annually on unplanned repairs. What if wind turbine monitoring detected blade damage before it becomes catastrophic – and could give operators a clear strategy to prevent failure?

That’s what Fibersail, based in Portugal, with offices in the Netherlands, has developed with its innovative fiber optic sensing system.

Fibersail CEO Carlos Oliveira joined us to discuss why they developed this new turbine monitoring system, what they learned along the way, and how it’s working for wind farms around the world.

You can listen to the interview here or read the highlights below.

The Future of wind turbine Monitoring

As the wind industry continues to scale and turbines grow larger, the need for advanced monitoring systems has increased as well. Fibersail’s fiber optic technology represents a fundamental shift from reactive maintenance to predictive maintenance, potentially saving the industry billions while improving the reliability of renewable energy generation.

Wind Turbine Monitoring is a Billion-Dollar Problem

Most operators face the same stark reality: traditional monitoring systems simply aren’t equipped to handle today’s massive turbine blades. As Oliveira put it, “We are building bigger and bigger blades, using old technology. It does not work.”

Where turbines once showed problems after 5-8 years of operation, today’s operators routinely see major blade issues within the first year or two of operation—sometimes even during the warranty period. This dramatic change has led to some major companies recognizing billions in losses due to blade-related issues. It’s conceivable – realistic, even – that if this trend continues, it could put the entire wind industry at risk.

Why Go Beyond Traditional SCADA Systems?

Most wind turbines today rely on SCADA (Supervisory Control and Data Acquisition) systems for monitoring, but they weren’t designed to detect the structural issues that lead to blade failures. Fibersail’s fundamentally different approach brings advanced sensing technology directly to the blade structure.

The company’s fiber optic technology provides real-time data about blade behavior that simply isn’t available through conventional monitoring systems.

The Shape-Sensing Revolution

Fibersail’s innovation is its unique “shape sensing” technology. The concept originated from measuring sailboat sails and has evolved to monitor wind turbine blades—essentially treating each blade as a “rooted sail.”

Here’s how it works:

  • Fiber optic sensors are installed directly inside the blade, running from root to tip
  • The system monitors the blade’s shape in real-time, detecting minute changes that indicate structural issues
  • Dual validation occurs by monitoring both shape changes and frequency variations
  • All complexity is encapsulated in a robust system that field technicians can easily install

A Pragmatic Implementation Strategy

Ideally, a sensing system that is built into the blade would be an OEM integration, but Fibersail knew that would delay market entry, possibly for years, while operators and quite possibly the industry – ran out of money and out of business.

Rather than waiting for OEM integration, then, Fibersail began working directly with wind farm operators—the ones who face the immediate financial impact of blade failures.

“The owner-operators are the ones who have the problem to solve,” Oliveira explained. And by working directly with wind farming operations, Fibersail is better able to gather real-world data to prove how the sensing system saves blades, and money. The strategy is paying off.

The company is currently collecting field data from multiple installations, with promising early damage detection and damage propagation projects underway. This real-world validation is crucial, Oliveira emphasized, saying, “Nothing is as valued as the data from the field.”

installation data from Fibersail

From Data to Actionable Intelligence

Perhaps most importantly, the data Fibersail provides is not just graphs and charts, but actionable intelligence. Oliveira calls the solution “elegantly simple.” When the Fibersail system detects a problem or potential damage propagation, it sends an email alert to operators, allowing them to prioritize their limited maintenance resources effectively, and to focus on turbines that need immediate attention, while allowing others to wait for scheduled maintenance.

Blade Manufacturing: Variations Happen

Unfortunately, in working with wind farm operators, Fibersail has seen firsthand the frustrating reality of blade manufacturing variability. While blades are theoretically identical when they leave the factory, manufacturing tolerances mean each blade is slightly different. Add a few years of operation, repairs, and patches, and operators end up with what Oliveira colorfully describes as “Frankenstein turbines.”

This variability makes traditional numerical models inadequate for predicting real-world blade behavior – and it highlights the need for actual sensing technology.

Overcoming Installation Challenges

One of the biggest hurdles in the industry is navigating warranty restrictions and service agreements that can prevent operators from installing aftermarket monitoring systems. Fibersail positions itself as a solution provider for the entire industry, not just for the owners and operators, but also working with manufacturers and developers.

The company aims to create three-way partnerships between Fibersail, the customer, and the OEM when possible. The entities are more likely to work together when they see how the technology benefits all parties, by reducing costs and improving reliability – always a key to navigating warranty issues.

Oliveira noted that Fibersail understands its customers need to comply with strict cybersecurity requirements, which is simply a necessity in today’s complicated energy industry.

Tailored Solutions at Scale

Fibersail offers a modular product line that can be customized based on customer equipment, site conditions, and other operationall factors, including –

  • Basic load sensors for customers needing fundamental load data
  • Shape sensors for early damage detection
  • Hotspot sensors for comprehensive damage monitoring
  • Integrated systems combining multiple sensing technologies

Because of the company’s flexible offerings, customers can start with a basic monitoring system and add complexity as needed.

Expanding into Offshore

While Fibersail is currently focused on onshore installations, the company is expanding to offshore applications, with the first Fibersail offshore installation in the Netherlands planned for this summer. In the more challenging offshore environment, the company expects that the return on investment will be even greater.
