Uptime 197
Allen Hall: Phil, did you see that in Australia during a tennis tournament that they had a deadly snake appear on the court?
Philip Totaro: Yes. I know.
Allen Hall: Rosemary’s not here to defend herself, but, oh my gosh, she swears to me that when you walk around Australia, you’re not going to be attacked by a poisonous snake, and yet There it is, headline news in the United States, poisonous snake at turn, at tennis tournament.
So it was like the world’s most deadliest snake, whatever that snake is. Joel, do you know what that snake is? The world’s deadliest snake?
Joel Saxum: It was the second most, and it was like a brown. Some kind of pit, Viper Brown something. I don’t remember what it was.
Allen Hall: And there it was right in the middle of this to tennis tournament just sitting there.
Philip Totaro: Allen, you must not watch tennis that often because when they used to have the tournament in Miami before they moved it into the Hard Rock Stadium they used to have like lizards in invading the tennis courts and stuff like that. So yeah it’s not uncommon for that sort of thing to happen.
But lizards are nice. Most most of the time they won’t kill you.
Allen Hall: But in Australia, they totally will. Yeah, and we were watching you guys watch the Mike Rowe show? I like Mike Rowe. Dirty Jobs, there you go. And he was milking dangerous spiders, poisonous spiders. And the whole time, you got these massive spiders, and on the whole, I’m just watching this thinking, That’s what’s in Australia.
That’s what’s in Australia. Oh my god, that’s what’s in Australia. I, can I get that out of my head? That’s a dangerous place. Even though Rosemary swears it’s nice. I’m sure that it is. And Matthew Stead From Ping says the same thing, we’re gonna have to go, Joel. I hate to say it, but I’m not gonna be the first one to step off the airplane.
I’m gonna have someone go ahead of me. So my
Joel Saxum: brother lives in Alaska, and he told me this one time, he said, You don’t have to be the fastest one, you just gotta be faster than your buddy.
Allen Hall: Australia has become a renewable energy center. Of course, Rosemary points out that they’re full of solar, and they have Essentially a renewable energy grid at this point.
But the wind industry is growing out there. There’s been a lot of movement out that way. And I hope Vestas installs a plant out there. And this episode we’re talking about the advancement of Vestas where they had a huge project announcement and expanding their factories in Colorado. So this is going to be interesting because.
As Phil has pointed out, Vestas is making a move and it is big, so stay tuned.
Vestas have received its largest order ever in the U. S. market, 1. 1 gigawatts of turbines, which is about 242 turbines of the V163 4. 5 megawatt machines. That that are going to be built in Colorado for Pattern Energy’s Sunzea Wind Project in New Mexico, so right next door to Colorado. The turbines won’t have very far to go.
It is the largest order onshore for Vestas ever. It includes all the supply, delivery, and commissioning of the turbines and a, as Vestas has proven out, a multi year service agreement. So everybody around Pattern and Vestas is super happy. You remember Vestas had put some money in about 40 million into the two factories in Colorado, one’s a blade factory, one’s in a cell factory to expand them for this particular product line.
So this is working out for Vestas quite lovely at the moment, Joel. It seems the 4. 5 is going to be a pretty useful machine as the repowering efforts and new projects are developed in the United States.
Joel Saxum: Yeah New Mexico is a fantastic place to put a lot of these out too, right? Because where this project is sited at is It’s very rural.
It’s wide open spaces. It’s just if you’re familiar with looking at West Texas, it’s an extension of West Texas, basically. So these are some big turbines, right? These are the ones that you see from even a long ways away and say, wow, that thing is freaking massive. They’re going to have an 80 or that 163 meter rotor on them.
They’re going to have an 80 meter blade or a 79 meter blade on them. So they’re going to be some big machines. But the whole project here is the interesting thing. Because Sun Zia has been, that idea of a project has been around for a long time and that was always focused on the transmission part of it, right?
It was bringing this power from this idea of this development over towards Phoenix, crossing to Arizona and to feed that southwestern portion of the United States. And to me, I guess it was, maybe I wasn’t thinking correctly or whatnot, and suddenly they were like, Hey, Sun Z is good to go. Also, 1.
order with it. Congrats to Vestas and Pattern, really, for putting this thing together and finally getting it across the finish
Allen Hall: line. Phil, this is a big project for Pattern, isn’t it? Yeah, it’s
Philip Totaro: part of a 3. 5 plus gigawatt project. They’re spending 11 billion dollars on the entire thing, including the transmission.
Also went under the radar last week after Vestas made their announcement was that GE also made their announcement that They’re also going to be supplying some turbines. I don’t, actually, it’s funny because I don’t know if it’s actually for the rest of it the remaining 2.
4 gigawatts or not but there are three phases of this project, so it’s potential that Pattern may also want to or has yet to announce and explore a relationship with Siemens Gamesa or Nordex on that. If that’s what they’re doing, but in the meantime, yeah this entire project is it’s gonna be probably the biggest a onshore multi phase project outside of China China, there are places in.
there are Various deserts there where they’re doing something similar, they’re setting up just massive arrays of turbines and solar panels and everything. Outside of China, this is going to be the biggest onshore project in the country, certainly the country and the rest of the world.
So
Joel Saxum: Allen, I want to ask you a question on this one. Now, of course we can, from the armchair, we can sit and say, okay, this is going to be a three, three and a half gigawatt project. That’s crazy, right? The largest single phase installation in the U S is about one gigawatt. So this is three times. Of course it’s multi phase.
But we know that you probably can’t turn to Vestas and say, Hey, we need 700 V1 63s in the next 18 months. They’re not going to be able to do it. So we know that you need to probably, like you said, Phil, get some GE turbines in there, get some Vestas turbines in there. There might even be some other suppliers thrown in there.
So we know that’s just a reality from the supply chain standpoint. But on an engineering side, what does that do for the project?
Allen Hall: Holy hell it’s gonna be a big, complicated project, right? Here’s my concern about this whole project is, you’re putting all your money on the table, and you’re spinning that wheel.
A lot of these turbines haven’t been that well examined, right? And, yeah, and New Mexico’s a tough place. That’s what worries me. A lot of lightning, a lot of everything in New Mexico. The winds are strong, right? That’s why they’re there. You gotta wonder if something were to be bad on the turbine, boy, it would just explode.
This is the Siemens energy problem, right?
Joel Saxum: Man, yeah, it’s a complicated geographically, right? Because you have mountain mountains to the south in Mexico you have mountains that subtend the middle of Or the western side of this project in the middle of New Mexico And then you have that hot weather going off to the plains like it’s a complicated weather area as well strong winds Of course, that’s fantastic for the wind industry.
We deal with that all the time But also the tendency for microbursts and hail and really strong convective storms in that area.
Allen Hall: Yeah, the weather there is not great. The winds are good, but the big storms hit that part of New Mexico and that worries me. There’s just a lot of unknowns here. I would feel a lot more comfortable if this ended up in Oklahoma or Kansas or even Iowa, some places that we have a better understanding of.
Something this big in New Mexico. I don’t know
Joel Saxum: if we’ve been there before. I do think that the size of this wind farm complex, we’ll call it, has the ability to literally fuel an entire town. You’re gonna If you’re gonna have 700 some odd massive turbines, the workforce that’s going to be needed, you’re gonna need a hundred people out there regularly working on the thing that’s gonna, that are gonna be permanent residents of this area, which is a very rural area.
New Mexico is challenged For rural development and and job. So this is, it’s going to be a boon to that corner.
Allen Hall: To Phil, does this make sense in terms of the proximity? Is that part of it, of the Vestas production plants being pretty close and the tower plants are right there in Pueblo, I’m assuming.
So they’re not very far from the border of New Mexico. Is it a. Closeness that’s playing into the, to the part of this transaction that, that the factory is right up the street. Part of it,
Philip Totaro: certainly. And keep in mind that Vestas obviously sold the tower manufacturing to CS Wind and CS Wind actually just released some new projections, financial projections based on presumably the fact that they’re getting, a lot of these and other of the Vestas turbine orders.
Vestas now has, I believe, something on the order of 3 to 3. 5 or 3. 6 gigawatts worth of V163 orders now globally. Which is great for that platform. Although, like you say part of it’s unproven, certainly the blade is a new blade. It’s based on their pre existing technology, but it’s not a product that’s been out there.
GE, my understanding is that they’re going to be using the 2. 8 127s and, 2. 3 to 2. 5, 116s. Nothing that hasn’t been previously experienced there again, the question is would a company like Pattern Energy take a punt on the Nordex N 155 or N 163 or are they gonna, I don’t know what happens with Siemens Gamesa, if they’re going to be prepared to start supplying turbines.
Now that we’re in 2024, happy new year, everybody we’re, are, is Siemens Gamesa going to start selling and supplying turbines again this year for delivery later this year and into next year, which is that project is going to be under construction for. They got a lot to, they got a lot to build.
Allen Hall: Phil, there’s two pieces to this that I’m trying to learn about. One is how fast is Vestas going to try to produce those turbines? Are they really going to try to ramp up these factories with the 40 million they’ve invested in? To then rapidly turn around these turbines, or they can try to spread it out.
One, two, Siemens is in trouble. If they’re not able to get into some of these bigger projects, particularly on shore, which is a strength for them or has been historically. Does Vestas, which is looking very aggressive at the moment, really push Siemens out of the U. S. market, or try to, and then shove their way into that broader North American, South American marketplace?
Philip Totaro: If that, if the latter happens, Allen, what happens is Nordex basically takes over the number three spot in terms of U. S. wind turbine OEMs. So that would be interesting, but Nordex doesn’t have necessarily as competitive of a product offering it’s it, look at whatever metric you want the, Megawatt hours produced, the capacity factors, the and some of it is, they’re unfortunately disadvantaged by not having access to the best project sites, so they can’t really shine.
There’s nothing necessarily inherently wrong with the N149 or the N155 or 163 product platform. It’s actually a pretty solid product. But again that’s part of the issue is they’ve never really They’ve never even if Vestas starts taking business away from Siemens, and orders away from Siemens Gamesa, does that necessarily allow somebody like Nordex to flourish, or does it open up?
Is it just gonna be a knockdown drag out between GE then, a bunch of other small players also want to domesticate production in the United States. Does this open the door for them if they’re willing to come in and spend money? That’s, it’s a complicated, that’s a very complicated thing.
The other aspect of this, going back to your earlier question, was Yes, the proximity for the Vestas factories plays into them getting the supply, but also with these 45 X manufacturing tax credits that are providing a domestic content bonus, shall we say for domestic sourcing of some of the components.
That’s going to do a lot of good things both for Vestas and for Pattern because they’re going to be getting a pretty you’re talking about what, about, 550, 000 per turbine if they domestically source all the components that they can under that, that tax credit program.
So that’s a pretty decent chunk of the cost of the
Allen Hall: turbine. I want to. Tie in the Nordex piece because they did sign that extension with Eris down in Brazil to make blades down there. I’m wondering if that’s their fallback position, is to crank up Eris to make blades if they want to start going after some Siemens projects.
Philip Totaro: They’re, they have enough orders in Brazil and in adjacent markets in South America that the Eris thing is good. The question is, will Eris come, cause Eris has been talking about wanting to come to the U. S., now that we have this proposed regulations for the 45 X manufacturing tax credit. I wonder if that doesn’t, I think we’re going to see, for instance, I was mentioning this before off air, like companies like NGC with making your boxes in China, anybody.
That G. E. Vestas, Siemens Gamesa, or Nordex is using that’s a foreign company is going to want or probably need to domesticate some of their production capacity in the U. S. So that these companies can take advantage of it, because one of the provisions of this is that you can’t just import foreign made goods and just assemble it.
That doesn’t qualify fully for That bonus, tax credit. So the question here is, does Ares, does this relationship that Nordex and Ares have in Brazil, does that then help facilitate the relocation of Ares to, set up a factory in the U S either
Joel Saxum: way. I think that there’s an interesting play here.
Like Phil, you’re talking, we’re talking about market share with Siemens and all these different things. In the last I don’t know, man, two weeks, up until the end of the year, it was like Vestas, watching LinkedIn, it was like Vestas had held all of their cards right until the end of the year, and they were like, Order for 400 gigawatts, order for 1.
1 400 megawatts, Boom. they do That, though. they Always announce, like, all their orders in bulk, at the end of every quarter, financial quarter. But this was actually, they they announced a total of 17 gigawatts, but it wasn’t all Firm Orders, it was something like 12.
Philip Totaro: 8 gigawatts of Firm Orders and then the rest of it was all preferred supplier and conditional orders. But it was still, it’s a huge order haul. And again with some degree of certainty, again, they haven’t finalized these 45x tax credit rules in the U. S.
And we don’t know what the profitability of some of these orders is for places in South Korea and throughout Europe with some of these offshore orders, but this is, it’s still a big deal. That’s a lot of orders to be able to announce in one quarter. And if you go back to November the CEO was basically hinting at the fact that they were going to drop all these orders, and it was going to be a big end of the year and
Joel Saxum: it turned out to be.
The interesting take from this whole thing that we’ve been talking about here for the last ten minutes is the fact that the IRA bill, as designed, A year and a half ago, is starting to do its job.
Allen Hall: Is it? Or the Treasury Department doing it?
Joel Saxum: To be, like, like Phil was saying, if you’re using an NGC type deer box or someone from China, there it’s, will force them to be competitive, it’ll force them to do some manufacturing in the United States.
That was the point of the IRA Bill in
Allen Hall: general. Yeah, I’m still a little dubious, because the time frame is too short. so if you’re Trying to build a factory in the United States and get up and running, that’s going to take two years minimum, especially for something that’s complicated as NGC.
So The chances of that happening, I think, are small. It’s going to be those that already have factories in place, like Vestas or GE, that could easily spool up something pretty quick.
Philip Totaro: Yes and no, because like I mentioned before, if they’re already qualified for the 48C manufacturing tax credit from a previous PTC authorization.
They can’t double dip on the 45X. This, the 45X and the IRA bill is intended to facilitate new build factories in the United States. The question though is, there these credits go until 2030. At the current rates that they have. And it, again, it works out to be about 120, 000 per megawatt for an onshore turbine, 140, 000 per megawatt for an fixed bottom offshore turbine, and 160, 000 per megawatt for a floating offshore turbine, however.
As Allen just mentioned, you’re talking about a scenario where it’s going to take, I’ll give them the benefit of the doubt and say 18 months, but you’re talking about a timeframe where you’re not even really able to pull the trigger because they took so much time to clarify these regulations and they’re still not even finalized yet.
Now we’re losing opportunity and we’re losing momentum on being able to take advantage of the domestication of the. Manufacturing facilities. The other question is, if this only really runs out to 2030 and then starts ramping down, and by 2032, the 45x tax credits go away, How many companies are going to be able to secure enough of an order book to be able to justify the factory investment, because you’re talking about if you’re trying to do a, if you’re a gearbox vendor like NGC and you’re trying to domesticate production of everything that, that, GE is going to need from you and keep in mind that NGC is not their only vendor, but you’re going to you’re going to need at least.
like Three gigawatts worth of orders to be able to pull the trigger on what is going to end up being like a three hundred to four hundred million dollar factory, give or
Allen Hall: take. that’s the Problem. But if somebody is looking to put U. S. content, and I do know of a company that’s based in the United States that manufactures parts for wind energy.
That’d be Weathergard, Lightning Tech, we’re in Massachusetts and we make the thing here. That’s right. Someone Can actually pick up the phone and call us because we’re it. We’re probably one of the few that actually is a vast majority. I wouldn’t say a hundred percent, but it’s damn close to it. U. S.
content. We’re easy. I know we’re s only we’re small. But still. That’s a good plug. Come on, Phil. Does it include Intel
Philip Totaro: Store, too? we Provide digital services any anywhere in the world. Doesn’t that
Joel Saxum: count? Phil is manufacturing insights from the data.
Allen Hall: Hey, uptime listeners. We know how difficult it is to keep track of the wind industry.
That’s why we read P. E. S. Wind Magazine. PES Wind doesn’t summarize the news. It digs into the tough issues, and PES Wind is written by the experts. So you can get the in-depth info you need. Check out the wind industry’s leading trade publication, PES wind@pswind.com.
Joel Saxum: So one of the things I talk about on the podcast fairly regularly is offshore wind operations because it’s a mystery. if You’re, looking at an onshore wind farm, or if you’ve been in oil and gas, you’ve been in construction industry, you’ve seen people build highways, these are massive infrastructure projects, but you see what’s going on.
You see a dozer driving, or a surveyor out there, or some people moving drainage stuff around, you can see all of that. But when you get to offshore wind, you can’t see any of that. You see a couple of vessels on the surface driving around, but you cannot see anything that’s going on underneath them. And that’s where all the work is happening.
VideoRay is is a part of that solution. Now, they’re in PES Wind Magazine this, this quarter talking about off, offshore wind inspections. Now, They don’t just do inspections with their equipment on the operation side. They do it during development, during construction and during operations.
So think of what a VideoRay offers as a solution being a basically a drone that you see in the air. Again, I’m trying to relate it to something everybody’s seen except for much more expensive and something that swims and swims sub C. The, it’s not, I’m not going to say it’s trivial to build a drone.
But it’s not super difficult. The concepts are pretty easy. Flying in air and communications and positioning is fairly easy compared to sub C because when you go sub C, you cannot communicate very well. You cannot position very well. Cameras are hard to use because contrary to popular belief, not everything sub C looks like the great barrier reef that’s beautiful and blue and clear.
So there’s a lot of. Technology that goes into these kits that they send subsea. So in the industry, they’re called ROVs. We think about them as remotely operated vehicles and VideoRay makes a couple of different models, but they’re in the inspection class. So there’s a couple of different ones.
There’s like your hobbyist that looks like a, a drone that’s smaller than you have the inspection class ROVs, which is what VideoRay makes. That are like 20 to 40 pounds or so, about the size of, I don’t know, like a cooler? Like a Yeti cooler or something like that? And then you go to the next level of things, which is like an intervention and work class ROVs.
Work class ROVs can be the size of a truck. they’re Freaking huge. but These pieces of kit that they have, they can do all kinds of things. They can inspect things visually. They can inspect with sonar. They can put manipulators, little hands on them. They can grab things off the floor. Or off the seafloor.
They can test with NDT probes. So you can check the thickness of metal. You can check cathodic protection on things, which is basically the kind of metal blocks you put subsea to combat the seawater and alkaline steel interact, or metal interactions. So they can do a lot of things. if you’re On an SOV offshore or on any kind of construction vessel, these Little ROVs are out there.
They’re watching rock dumps to make sure that they’re laying in the right place. They’re watching cable inspection. They’re doing cable inspections. They’re watching cable hookups. Sometimes the work class ROVs down there and the inspection class is standing off just to watch what they’re doing.
They’re mapping things. They can map rock dumps, map the surface of the floor. They can do visual inspections. They can create. 3D models of monopiles and, all kinds of things subsea, so they’re very powerful tools. I think that VideoRay’s got about 4, 000 of them. When I was in oil and gas, VideoRay was a company that you thought of all the time.
Hey, we gotta get this inspection class over. Yeah, grab one of those VideoRay. Boom, throw that on board. That was something we always used. They’re using the defense space, oil and gas, civil construction, everything offshore. Inspecting nuclear plants, all kinds of cool stuff. so Think of them as a drone in the sky, but underwater.
However, they’re much more advanced. VideoRay’s Starting to use AI to do station keeping and model building and inspections. Because if you’re driving down a pipeline with a ROV, you’re just going pipe joint, oop, little bit of free span there. It’s very monotonous and very manual for the operator to do, but with AI, now you can Automate a lot of those tools. The last bit I would say here, and this is a, an idea because we’re always looking for what could be better in the wind industry. What’s innovation. What’s cool. If I was inspection company that had people mobilized around the world with drones, inspecting blades, cells, transition pieces offshore, which are part of regular tenders now.
I would also start to include inspecting subsea at the same time. And here’s the reason. You’re already there, you already have specialized employees out there, and the vessel is standing by while you fly with the drone. You might as well throw the ROV overboard and do the subsea portion of the inspection at the same time.
Now you can deliver the client value add. So you’ve got an inspection from the tip of the blade all the way to the seafloor. And you’re using the same people and the same vessel time. And that’s the big thing that costs offshore. So if you want to do that as an inspection company, call me,
Philip Totaro: I’ll walk you through.
So it sounds like there could be some acquisitions in the the in remote inspection space there should be. And if
Joel Saxum: this is the big thing to if you’re a company that has a platform, that’s looking at assets that, you have like sky specs is the nice horizons platform or. Everybody at Perceptual Robotics has their platform and ZiteView has their platform and Thread has their platform.
You should be putting in a module in that to manage that subsea data at the same time. And
Allen Hall: if you want to stay abreast of all the cool technology pieces in the wind industry in 2024, you better get the Q4 edition of PES Wind from 2023 because it is full of cool technology and it has a lot about what’s about to happen.
So you’re going to see a lot of technology in PES Wind in this latest edition. You’ll see it out in the field, come up in a couple of months when it warms up, up in the Northern Hemisphere. So check it out. You can go to PESWind. com. You can get a free, download and you can read about all the things we, we talk about in the podcast.
back in November The Department of Energy proposed a rule to speed up environmental reviews for some renewable energy projects. The proposal would have, or does expand exclusions that allow faster review of projects with minimal environmental impacts. Now, there’s a number of projects or project types that would apply it here to solar arrays, power line upgrades, batteries, flywheel storage systems, things that are pretty much neutral in the environment and have shown years of history of doing such.
Thank you very much. The one item that is not in that list is wind turbines. And I think basically anything over 200 feet tall applies where you have to get the environmental impact done, even though that has been accomplished at this point, Joel, hundreds of times in the United States. And there really hasn’t been any issue, but they the DOE kept, the environmental reviews the way that they have been historically for wind projects.
And I think the wind industry has got to scratch their head about this because that was an opportunity to make the process simpler, and they decided not to do it. So they gave it to solar on some level, and they gave it to power lines, fine, just power lines. However, come on, let’s, what has wind energy done to deserve the this they should have been able to use the history of wind projects being cited and installed.
And they have years of data, 20 plus years really of data. Why would they not? Shorten the time period these environmental
Joel Saxum: reviews happen to me. It seems like there’s an easy way to do this, right? if you Have a categorization that you fall under certain citing rules and design rules, operational rules, if you fit in that box, you shouldn’t have to go for this extra.
different kind of DOE big play. I think that if you’re going to have intense rules, or if you want to really regulate something and it’s on say BLM land, like Bureau of Land Management, federal land or something of that sort, I can understand that’s public land that has public interest to it.
but if Private entities are building on private land, for the good of the environment or the, for the good of the public, I don’t see why there should be. Long queue lines and intense rules for that.
Allen Hall: Phil, does this make sense with everything else that’s happening in the DOE and the Treasury Department trying to speed up wind industry development and installation of wind turbines?
This is one of the roadblocks. Every time, for every project, this is one of the roadblocks. It just eats up a bunch of time.
Philip Totaro: And remember back to my infamous rant last year about, how all these projects based on that study that was done by, Columbia University, there’s, 45 states that have some kind of regulation on or restriction on wind and solar development.
And the fact that we’ve never had cohesive and unified federal policy that allows for a consistent permitting application review process, we’ve never had, with the exception of rules that have been established for, what’s done on public lands. but Again, that’s not a streamlined process like we’re talking about.
the fact that they Would streamline the process for other things but not wind, I really don’t get it. we’re Now six or approaching seven percent probably by the end of 2023 now of the domestic electricity production and generation in the United States. We’re still, at this point, bigger than solar, although they’re catching up quick, but what do we have to do?
Allen Hall: Yeah, I don’t know, I don’t understand why the DOE is not having this discussion internally or why someone over there didn’t say, hey. What about wind? It’s a political issue. That’s what, okay, that’s what I wanted to get to. The
Joel Saxum: problem is it’s a political issue because they’re visible and it’s a partisan issue.
Solar panels are visible? Yeah, it’s not a technical argument anymore. It’s a political argument and that’s the
Allen Hall: problem. So do you think it was left open because there’s a pushback because of the size of the turbines and some, at some point we can have another Ted Kennedy situation where a senator can just essentially stop it.
in their Backyard. is that what This is about? Because this is getting to be a little ridiculous. and if, but that Shouldn’t, that doesn’t prohibit states from blocking projects on their own, right? They totally can. And why wouldn’t they, right? But in, in places like, Texas, Oklahoma, Kansas, Iowa, Illinois, Indiana, where there is a process in place at the state level, what, and have, they have historical data that shows they can develop these projects without all these environmental reviews, then what are we doing?
It’s confusing to
Joel Saxum: me. It even goes farther than environmental reviews as well, because I read an article today that stated Avangrid was going to buy PNM and they backed out of it because PNM. Did not get regulatory approval of, for the acquisition.
Allen Hall: So is that what they anticipate that the feds would object to the acquisition?
And so they were just hedging their bets that it’s just going to take, or they just felt like it’s going to be a long time for the reviews to
Philip Totaro: go through. It’s already been, they’ve been working on this for four years or five years already. So
Allen Hall: is, does that mean that the Fed, at the federal level, it’s taking too long?
it’s been four or five Years and they haven’t gotten all the paperwork through that they needed to? Is that what that, what this all indicates? I
Philip Totaro: think there’s probably a backroom, there was a backroom discussion that was basically like, this isn’t gonna happen, so they pulled the plug.
Joel Saxum: And it’s, there’s articles, from June April, June, July of this year that are like, We, this is going to be, this is going to happen.
This is going to be fantastic. Merger is going to go through and then
Allen Hall: you go. What’s the objection here. It’s just the size of the project of the exchange. And the resulting company, is that what it is, or is it bigger than that? That’s some of these acquisitions and mergers, how they’re not getting through the SEC.
Joel Saxum: The article today was Reuters. Eberdrola’s Avangrid, so Avangrid terminates 8. 3 billion deal to buy PNM resources. They terminated it today. And there’s no reason given. It’s, it says, because it could not get all the necessary regulatory approvals to close the deal by December 31st. Wow. Delays it from the federal.
Probably FERC and someone else. A regulatory, what else would regulatory be in that SEC maybe? Sure,
Allen Hall: that would have to be a part of the review process, right? Just because of the size of the transaction and who’s involved and it’s an energy
Joel Saxum: transaction. The deal worth 4. 3 billion excluding debt was unanimously approved by PNM’s board in 2020 and was expected to create a renewable energy operator with a combined market value topping 20 billion.
There’s
Allen Hall: going to be a lot of transactions happening in the next 24 months from what I can tell. And if there’s going to be a regulatory hurdle, then a lot of them are going to be stuck. And that’s, this is not the time for that to happen. What would be the concern? I don’t. There’s been so many other transactions across the world at the moment in renewable energy, why that one?
Again, is it politics, Phil? yeah, part Of it, but that’s, was gonna be my point, is I could see them putting a kibosh on a deal if it was like a Chinese parent company was coming in and trying to buy something, but this is a Spanish company that’s a huge utility and basically the biggest, owner operator of renewable energy in the world.
Philip Totaro: So I don’t get it. They
Allen Hall: backed out a couple of offshore wind projects in the state of Massachusetts.
Philip Totaro: But they just released that report about how many jobs they created. everybody Should be excited. They created more union jobs than expected.
Allen Hall: There is a big discussion about that in the state of Massachusetts because it has maybe created some union jobs but it’s squished some non union jobs and there’s Port and the people around the port aren’t super happy because a lot of people coming from the outside that area More to come there.
I’m sure and I and you know the thing think same things happen in New York It’s going to happen in New Jersey is going to happen up and down the east coast of United States is they try to show jobs because this is, hey, welcome to 2024. There’s going to be 10 plus months of this as good paying union jobs.
How many times are you going to hear that in the next 10 months? That’s just part of it, right? That everybody’s trying to show their credentials that they have created union jobs for these offshore wind projects, whether they. Have or not, unclear. That’s going to do it for this week’s Uptime Wind Energy Podcast.

Welcome to Uptime Spotlight, shining Light on Wind. Energy’s brightest innovators. This is the Progress Powering tomorrow.
Allen Hall: Nicholas, welcome back to the show.
Nicholas Gaudern: Thanks, Allen. Always a pleasure.
Allen Hall: Well, there’s a lot of new products coming outta PowerCurve. And PowerCurve is the aerodynamic leader in add-ons and making your turbines perform at higher efficiency with less loss. Uh, so basically taking that standard OEM blade and making it work the way it was intended to work.
Nicholas Gaudern: Yes. We
Allen Hall: like to
Nicholas Gaudern: think so. Yeah.
Allen Hall: And there’s a, there’s a lot of new technology that you’ve been working on in the lab that you haven’t been able to explore to the, introduce to the world, so to speak. Yeah. And we’ve seen some of it from the inside of, you know, you’re working behind the scenes or working really hard to get this done, but now that technology has been released to the world, and we’re gonna introduce it today, some new trailing edge.
[00:01:00] Components. Yeah. That really, really reduce the noise. But they, they look a little bit odd. Yes. There’s a lot of ADON dams going on with
Nicholas Gaudern: Yeah.
Allen Hall: With these. So what, what do you call these new trailing edge parts?
Nicholas Gaudern: So, so what you have in your hand here? This is the Silence edge, uh, serration. So this is our new trailing Edge Serration products.
Now, most people, when they think of training restorations, they are thinking of triangles.
Allen Hall: Exactly.
Nicholas Gaudern: These Dino tails. Dino Tails, that’s the Siemens, Siemens name for them. Pretty, pretty standard. You see ’em on a lot of turbines now. Sure. And they work, you know, they do do a job. They do a job. They reduce noise.
But like with lots of things in, in aerodynamics, there’s lots of different ways that you can solve a problem and some are better than others. So we’ve worked for a long, long time in the wind tunnel, uh, in the CFD simulations, and we’ve come up with this pretty unique shape. We think,
Allen Hall: well, the, the, the shape is unique and if you, if you look at it, there’s actually different heights to the, the triangle, so to speak.
To mix the air from the pressure and the [00:02:00] suction side to reduce the, the level of noise coming off the blade
Nicholas Gaudern: e Exactly. So we have, uh, we have an asymmetry to the part. We have these different tooth lengths. We have, uh, a lot of changes in thickness going on across the part. So it may be a little bit difficult to see on the camera, but these are quite sculpted 3D components.
They’re not, they’re not flat stock white triangles. No, no. There’s a lot of thickness detail going on here. We’ve paid a lot of attention to the edges. We’ve paid a lot of attention to these gaps between the teeth as well. So all of this is about trying to figure out what is the best way to reduce noise.
And something that not a lot of people will, will admit, but it’s true, is that as an industry we don’t really understand the fundamentals of how serrations work.
Allen Hall: It’s a complicated
Nicholas Gaudern: problem. It’s a really complicated thing. Problem, yeah. Yes. So trying to simulate it in CFD is an absolute nightmare. The, the mesh sizes required, the physics models required are really, really difficult.
So what we found is that you’re probably better off spending [00:03:00] most of your time and money in the wind tunnel. Yes. So, so we go to DTU, they have this wonderful, uh, air acoustic wind tunnel, the pool of core tunnel. It’s one the best tunnels in the industry for doing this kind of work. It
Allen Hall: is
Nicholas Gaudern: because you can measure acoustics and aerodynamics at the same time.
So this allows us to do a lot of very cost effective iteration for this kind of design work. So we know what’s important. You know, we’ve, we’ve studied all the different parameters of serrations lengths, aspect ratios, angles, thicknesses, all this kind of stuff. And it’s about bringing them together into a, into a coherent product.
So this is, this is a result of a lot of design of experiments, a lot of iteration, and combining wind tunnel and CFD to kind of get the best of both of those tools. So,
Allen Hall: so what’s the. Noise reduction compared to those standard triangular trailing aerations. Yeah.
Nicholas Gaudern: So there’s lots of different ways of, of thinking about noise reduction, but I think probably the most useful is the O-A-S-P-L.
So this is the overall sound pressure level. Right. Is kind of what [00:04:00]typically you’ll be measuring in an IEC test.
Allen Hall: Right.
Nicholas Gaudern: And that’s measured in decibels, but a way to decibels because it’s important that we’re waiting to what the human ear can actually hear. Right. Perceive. Exactly. So that’s the numbers we report.
For the field test we’ve recently completed with Silent Edge, we’re seeing up to five decibels of O-A-S-P-L noise reduction.
Allen Hall: Okay. So what’s that mean in terms of what I hear on the ground?
Nicholas Gaudern: So that is an absolutely huge reduction. It’s multiple times of reduction because you know, decibels on a log scale,
Allen Hall: right?
Nicholas Gaudern: So five DB is is enormous. It’s
Allen Hall: a lot. Yeah.
Nicholas Gaudern: And what’s really interesting is that if you have a turbine that’s running in a noise mode, just one decibel reduction. Of power, sound, sound, power level might be three or 4% P loss. I mean, that, that’s, that’s huge. Think about that loss. So if you need to reduce noise by five decibels to get within a regulation, imagine how much a EP you have to throw away by basically turning down the [00:05:00] turbine to do that.
Allen Hall: That’s right.
Nicholas Gaudern: So that’s really what the, the business case for these kind of products is. It means you can escape noise modes because as soon as you use a noise mode. You are throwing away energy.
Allen Hall: You’re throwing well you’re throwing away profits.
Nicholas Gaudern: Exactly.
Allen Hall: So you’re just losing money to reduce the noise.
Now you can operate at peak.
Nicholas Gaudern: Yep.
Allen Hall: Power output without the creating the noise where you have that risk. Right. So, and particularly in a lot of countries now, there are noise regulations. Yes. And they are very well monitored.
Nicholas Gaudern: Yep.
Allen Hall: We’re seeing it more and more where, uh, government agencies are coming out and checking.
Yes. ’cause they have a complaint and so you get a complaint. Oh, that’s fine. Or someone can complain. Yeah. You know, you need to be making your numbers.
Nicholas Gaudern: Yep. And, and the industry needs to be good neighbors, you know? It
Allen Hall: certainly does.
Nicholas Gaudern: Uh, we have to make sure that people are, you know, approving and comfortable with having wind turbines in their backyard.
Sure. And noise is a big part of that.
Allen Hall: It is.
Nicholas Gaudern: So yeah. Ap sure. That’s really important. Being a good [00:06:00] neighbor also important.
Allen Hall: Right.
Nicholas Gaudern: Meeting the regulations. Obviously you have to meet the regulations. So this product, um, has been through a really long development cycle, and we’re now putting the final touches to the, to the tooling.
So this is available now.
Allen Hall: Oh, wow.
Nicholas Gaudern: Okay. Great. Um, and we’re hoping that in the next uh, few months we’ll be getting even more turbines equipped out in the field with, with the technology.
Allen Hall: So, oh, sure. There’s a, you think about the number of turbines that are in service, hundreds of thousands total worldwide.
A lot of them have no noise reduction at all.
Nicholas Gaudern: No. No.
Allen Hall: And they have a lot of complaints from the neighbors.
Nicholas Gaudern: Exactly.
Allen Hall: Trying to expand wind into new areas, uh, is hard because the, the experience of the previous Yes. Neighbor
Nicholas Gaudern: Yep.
Allen Hall: Grows into future neighbors. So fixing the turbines you have out in sight today helps you get the next site.
I know we don’t always think about that, but that’s exactly how it works. Yeah, of course. Uh, we need to be conscientious of the people of the turbines we have in service right now. So that we can continue to grow wind [00:07:00] globally and more regulations on noise are gonna come unless we start taking care of the problem ourselves.
Nicholas Gaudern: Yep. And another really important thing with Serrations is that you have to design them so that they don’t impact the loads on the rest of the turbine.
Allen Hall: Right. And people forget about that.
Nicholas Gaudern: Yes.
Allen Hall: Can you just, can’t just throw up any device up there. And think, well, my blade’s gonna be happy with it. It may not be happy with that device.
Nicholas Gaudern: You have to really carefully understand what the existing blade aerodynamic signature is.
Allen Hall: Sure.
Nicholas Gaudern: How is that blade performing? What is the lift distribution across the span? Yeah.
Allen Hall: Right. Yeah.
Nicholas Gaudern: So what we do, and we, we’ve talked about it before we go and laser scan blades. We build CAD models, we build CFD models so we can actually understand how much lift a blade can take and what’s the benefit or the penalty of doing so.
So these serrations are designed by default to be load neutral. They won’t increase lift. They won’t reduce lift. That’s what
Allen Hall: it should
Nicholas Gaudern: be. That’s where you should start,
Allen Hall: right?
Nicholas Gaudern: And maybe there’s some scope to do something else [00:08:00] on certain turbines, but you shouldn’t, you shouldn’t guess. You, you need to calculate, you need to simulate, you need to think very carefully about that.
So that’s what we do with these, uh, with these serrations, we go through this very careful aerodynamic design process to make sure that they reduce noise and that’s it. They don’t increase loads, they don’t reduce AP by killing lift. And that’s, that’s an important aspect.
Allen Hall: Well, that’s the goal.
Nicholas Gaudern: Yes,
Allen Hall: exactly.
I don’t necessarily want to increase power. I don’t wanna put more load in my blade, but people do that. I’ve seen that happen and man, they regret it.
Nicholas Gaudern: Yeah, regret it. There’s, there’s some pretty wild claims out there as well about observations can and can’t do. And uh, like with lots of things, it’s important to just do the simulations, speak to some experts and, um.
Yeah, maybe take the, the less exciting path, you know, sometimes,
Allen Hall: well, no. Yeah. Well, less exciting path where I don’t have a broken blade.
Nicholas Gaudern: Yeah, exactly.
Allen Hall: Yeah. That’s a lot less exciting. It’s, it’s definitely more profitable. Now, the Dragon Scale Vortex generator has been [00:09:00] around about a year or so.
Nicholas Gaudern: Yep, yep.
Allen Hall: And the thing about these devices, and they’re so unique, interesting to think about because you typically think of a vortex generator as this being this little bit of a fence.
Where you are tripping the air and making it fall back down onto the blade.
Nicholas Gaudern: Yep.
Allen Hall: A really, it works.
Nicholas Gaudern: It works.
Allen Hall: But it’s it’s
Nicholas Gaudern: been around a long time.
Allen Hall: Yeah. Yeah. It, it does, it does do this thing. And they, they were, they came outta the aviation business. We use ’em on airplanes to keep air flow over the control surfaces so we can continue to fly even in close to stall conditions.
All that makes sense. And airplanes are not a wind turbine.
Nicholas Gaudern: Yes.
Allen Hall: So there’s different things happening there. So although they work great on on aircraft, they’re not necessarily the most efficient thing for a wind turbine where you’re trying to generate power and revenue from the rotation of the blades.
Nicholas Gaudern: Exactly.
Allen Hall: So this is a completely different way of thinking about getting the airflow back onto the blade where it produces [00:10:00] revenue.
Nicholas Gaudern: And what’s really nice is to actually see this together with silent edge, because historically, and maybe not even historically. Serrations VGs, they’re triangles. They work, they do a job.
But that doesn’t mean you can’t do it in a different way. In a better way.
Allen Hall: Right.
Nicholas Gaudern: And that’s the same principles from applying with Silence Edge and Dragon Scale. We want to work the flow in the most efficient way possible.
Allen Hall: Right. You’re trying to get to an
outcome.
Nicholas Gaudern: Yeah, exactly.
Allen Hall: Efficiently.
Nicholas Gaudern: We want to, we want to target very specific things on the blade, and that’s where you can see there’s a few different styles of Dragon Scale that we have on the table here.
We have some that are two fins. We have some that are three fins. We have different sizes, and this is because they’re tailored to different parts of the blade. So these three Fin Dragon scales, their focus is ultimate lift. We are creating a really powerful vortex through this combination of three air foils, if you imagine, um, the inside of a Turbo fan.
You have these cascading air force. [00:11:00] You look at the leading edge slacks on an aircraft. You look at the front wing of a Formula one car. It’s that kind of concept.
Allen Hall: It’s like that,
Nicholas Gaudern: and it’s these air force that are cooperating with each other.
Allen Hall: Right.
Nicholas Gaudern: To end up with a more beneficial result. ‘
Allen Hall: cause an air force by itself does a function, but when you combine airflows together in the right way
Nicholas Gaudern: Exactly.
Allen Hall: You can really control airflow efficiently, less losses. More of what you want out the backside. Yeah, exactly. It’s, it’s the backside you’re trying to work on, on a VG or, or dragon scales. You’re trying to create this flow which gets the airflow back onto the blade to create power. We,
Nicholas Gaudern: we want as much attached flow as possible and down exactly down in the roots of a blade.
We have to have really thick aerofoils, you know, blades about round. They’re basically cylinders.
Allen Hall: Yeah.
Nicholas Gaudern: And that, that’s essential, right? We have to have the blade take a lot of load into the root aerodynamically. They’re horrible.
Allen Hall: Yeah.
Nicholas Gaudern: So this is where these, uh, these powerful Dragon Scale VGs come into play because what they do is they’re [00:12:00] reenergizing the flow over the aerofoils, and they’re ensuring that that flow remains attached for much, much longer than if those bgs weren’t there.
So down in the root, you’ll get significant boosts to the lift that those sections can generate. And what’s more lift? It goes to more torque, it goes to more power, goes to more a EP. So these dragon scale VGs in the root are there to boost, lift, and boost EP out on the tip of the blade. Things are actually a little bit different because it’s way different.
You shouldn’t really have stall there to begin with if your blade’s been designed well.
Allen Hall: But if you have leading edge erosion exactly. Or some other things that are happening, you can have real aerodynamic problems.
Nicholas Gaudern: So yeah, as soon as you have erosion, uh, maybe your stall margin is not as big as you thought it was.
You’re starting to get some significant losses of lift Yes out towards the tip of the blade. So that’s where these, uh, TwoFin uh, variants come in. So it’s still a dragon scale vg, it’s still the same concept of these cascading error foils. Yeah, but these are [00:13:00] designed for basically ultimate lift to drag ratio.
Mm-hmm. So we don’t really want more maximum lift outta the tip. We kind of have enough, but what we do want is to keep stable attached flow and we want to do it for the less, uh, least drag penalty possible. So basically we want to get rid of as much parasitic drag as we can. These two fin dragon scales, we are seeing 25 plus percent improvements in lift to drag ratio.
Compared to a standard triangle vg. I mean that’s huge.
Allen Hall: That that is really
Nicholas Gaudern: huge.
Allen Hall: That’s huge, right? Because people have seen these, uh, triangular VGs in a lot of places. And one thing I’m noticing more recently is that those VGs, because they’re so draggy, they tend to flutter and they tend to break in just off.
Nicholas Gaudern: Interesting.
Allen Hall: So you’re having this failure mode because this thing is just blocking the air, getting the air to trip.
Nicholas Gaudern: Yeah.
Allen Hall: It’s not efficient. It does have its downsides ’cause it is. D definitely drag. Just face it, it’s it, is it a draggy [00:14:00] 1940s technology? That’s what it is. Where with the dragon scales, now we’re doing things a lot more efficiently and thinking about how do I get the airflow that the blade designer originally wanted?
Nicholas Gaudern: Yes,
Allen Hall: because the blade designer, they’re really intelligent people. They’re, they’re sitting designing blades. But the reality is what you design is on an ideal airflow, and what you have out in service are totally different things. As, as it turns out, the shape of the airflow is not what you think it is because it comes out of the tool and there’s a lot of touching with by humans that are grinding on the leading edges and doing the things that have to be done to manufacture it.
So you don’t really have an ideal blade when it comes out of the
Nicholas Gaudern: No. You
Allen Hall: never do factory. No, you never do.
Nicholas Gaudern: And it’s not polished either.
Allen Hall: It’s not polished. Right. So
Nicholas Gaudern: when you go to the wind tunnel, you have a perfect profile. Yes. And it’s polished. And it works basically. It
Allen Hall: works great. It
Nicholas Gaudern: works great.
Allen Hall: The theoretical and the actual match.
Yeah. In reality they do. I think a lot of operators are not [00:15:00] connected with that reality of, Hey, that Blade should be producing this amount of revenue for me, and it’s not. And you hear that discussion all the time, particularly in the us. It should be producing this amount of power. I’m doing all the calculations.
We are not producing that power. Why? The blade length’s saying, but the power’s not coming out of it. Well take a look at your leading edge, take a look at your yard full of shape and realize you’re going to have to do something like dragon scales to get that E energy. Exactly. Revenue back.
Nicholas Gaudern: You need to do a full aerodynamic health check.
Basically you do. And see what are all the possibilities to improve my blade performance. And some of it is down to the fundamental shape of the blade,
Allen Hall: right?
Nicholas Gaudern: But some of it is down to blade condition. Yes. Blade Blade manufacturing quality.
Allen Hall: Yes.
Nicholas Gaudern: Uh, what kind of paint did they put on it? What day of the week was it made?
And all these things can be compensated for by VGs and you’ll get more revenue out at the end.
Allen Hall: You say? ’cause what happens? The, the, the scenario which is hard to visualize unless [00:16:00] you’re an A and emesis, is that there comes on the suction side, and it should be, in a ideal sense, rolling all the way to the back edge of the blade and coming off.
What happens is though, is that. When you get leading edge erosion is that the air flow actually separates. Yeah.
Nicholas Gaudern: It
Allen Hall: doesn’t
Nicholas Gaudern: always make it, yeah.
Allen Hall: Doesn’t make it to the back edge. Yeah. And so you can see that, especially if, if there’s dirt in the air, you can look on dirty blades, you can see where that separation line is, and a lot of operators have sky specs, images or Zeit view images, and then go back and look at the blades.
It takes two minutes to go. I have
Nicholas Gaudern: particularly down in the root, you’ll see it.
Allen Hall: Oh, in the root all the time. You, you
Nicholas Gaudern: see it really clearly that that separation line
Allen Hall: all the time, you really see that separation line. I’m seeing it more and more up towards the tip. Interesting. That’s where the lightning protection, yeah.
Systems sit.
Nicholas Gaudern: Yeah.
Allen Hall: I see a lot of airflow that is not front to back on the suc. Well, you
Nicholas Gaudern: have a lot of three dimensional flow out there.
Allen Hall: You do towards the tip you do. And you realize how much power you’re losing there. And I think operators are just throwing away money.
Nicholas Gaudern: Yeah, exactly.
Allen Hall: So you could [00:17:00] put dragon skills on it very efficiently, very quickly.
Get that revenue back into your system and it’s gonna stay. So even if leading edge erosion happens, the dragon scales are gonna compensate for it. It’s gonna get the airflow back where it should be.
Nicholas Gaudern: Exactly. And the nice thing about this is, you know, we are building on well over a decade of upgrading turbines with aerodynamic components.
Oh yes. So this technology stands on the foundations of all of that work. In terms of the materials, the work instructions. Um, the fatigue calculate, you know, everything
Allen Hall: Yes.
Nicholas Gaudern: Is built on thousands of installations that we’ve done. Yes. So, although it’s a new technology aerodynamically, it’s not really new in lots of sensors.
Allen Hall: Well, I look at it this way. If you turn on Formula One today and look at what the new generation of cars running around as you look at the, that front. Yes. Uh. Fin. Yeah. What do I call it? Air foil shape in the front. It’s super complicated.
Nicholas Gaudern: The sculpting of the [00:18:00] surfaces is really impressive,
Allen Hall: right? There’s a lot of thought going into those surfaces versus you turn on a Formula One race or go on YouTube and look at a Formula One race from the 1980s.
Yeah, it’s basically a piece.
Nicholas Gaudern: Yeah.
Allen Hall: To provide down downforce. That’s it. The aerodynamics wasn’t really there, so we come a long way and a lot of that technology that happens in Formula One that happens in aviation eventually rolls down into. Yeah. Wind.
Nicholas Gaudern: Exactly
Allen Hall: right. So we, we, although we are not designing Formula One style blaze today, we’re taking that same knowledge and information and we’re applying that back in.
Nicholas Gaudern: Yeah. We’re
Allen Hall: secondarily we,
Nicholas Gaudern: which is a right thing to do. We’re taking, taking inspiration from all these different aerodynamic fields and, you know, picking the best
Allen Hall: Yes.
Nicholas Gaudern: From what’s available and just allowing ourselves to be a little bit more creative.
Allen Hall: Yes.
Nicholas Gaudern: And thinking outside the box a bit. There’s so many ways to do this as we’ve been saying.
And the import. And the
Allen Hall: data’s there.
Nicholas Gaudern: The data’s there. Exactly.
Allen Hall: The data’s there because you’ve been at the DTU Yep. Uh, wind Tunnel, which also has the acoustic piece to it. Yeah. So you have measured data from a reliable source. [00:19:00] You have field data, and you know, you put all these together, you’re gonna get that improvement back.
You’re gonna get your invest back, you’ll be more profitable.
Nicholas Gaudern: So Dragon Scale, focus on the AP. And that a EP will, uh, vary depending on the turbine.
Allen Hall: Sure.
Nicholas Gaudern: But we’ll assess the turbine and, and decide the best configuration, and then say silent edge. That’s the focus on the noise reduction. And we’re seeing up to five decibels OASP on the field.
It’s, which
Allen Hall: is crazy.
Nicholas Gaudern: It’s even more That’s really good that we were hoping for, you know?
Allen Hall: Yeah.
Nicholas Gaudern: So we, we know this is gonna be a, a great product.
Allen Hall: It looks very interesting.
Nicholas Gaudern: It does.
Allen Hall: It does it. It looks complicated and you think air airflow is complicated. It’s a compressible fluid. It’s not easy to, to just assume it’s gonna do what you think it is.
Yeah. You need to get into the tunnel. You need to replicate, you need to do all that work, which is expensive in time consuming. That’s why you go to someone like Power. Curver knows what they’re doing in the wind tunnel, knows how to measure those things and know when they’re getting nonsense. Out of their computer.
I
Nicholas Gaudern: mean, you, you’ll pay thousands and thousands of [00:20:00] Euros dollars a day to run a wind tunnel.
Allen Hall: You will.
Nicholas Gaudern: You’ve gotta Absolutely. You’ve gotta turn up with your plan in hand, that’s for sure.
Allen Hall: Oh, oh yeah, yeah, yeah. And I think there’s a lot of assumptions because it, aerodynamics is hard. You know, you watch these blade spin around, you don’t realize how complicated these devices are.
They are complicated. Those air force shapes we are running today have been through a lot of history, a lot of history to get to where we are now. Now we’re just gonna take him into the next generation. This, we’re bringing ’em into the two thousands. In sort of a
Nicholas Gaudern: sense, what I’m hoping to see is, you know, with the OEMs, some OEMs do it already, but it’s important to think about these components when you’re designing new blades as well, you should because then that will allow you a much bigger design space to work in.
And
Allen Hall: a lot less customer complaints.
Nicholas Gaudern: Yes.
Allen Hall: Where’s my power?
Nicholas Gaudern: Exactly. You know, these products, particularly the VGs, are really important tools for PowerCurve robustness. And some OEMs have known this for a long, long time.
Allen Hall: Yep.
Nicholas Gaudern: And you’ll see VGs on most of their blades. Mm-hmm. Others not so much. And that’s a design choice.
It’s a design philosophy. Um, and I think it may not [00:21:00] be the right one, you know?
Allen Hall: Well, I think the operators are asking to get the most out of their turbines. Yeah. Why shouldn’t they? They should be asking for that.
Nicholas Gaudern: I think for a, for a long time, and it’s not just in wind devices, like these have been considered, you know, band-aids fixes when you’ve, you’ve messed something up.
But I feel that’s a really negative way to think about products like this. They’re doing something that the kind of raw air fall shape on its own cannot achieve. Sure. Oh no. Right. You know, you might be able to mold some interesting stuff. Uh, as part of the blade, it’s very difficult to, to recreate the kind of aerodynamic effects that these products, uh, have.
Allen Hall: Right.
Nicholas Gaudern: So they shouldn’t be considered bandaids or fixes. No. They should be considered opportunities. And ways that you can maximize performance and unlock areas of the design space that previously weren’t accessible to.
Allen Hall: Sure. Every possible component that deals with fluid air is moving this way.
Nicholas Gaudern: Yes.
Allen Hall: Jet engines, you look at jet engine, how much more is going into those jet engines today in terms of this kind of [00:22:00] technology?
Yeah. All the race colors, doesn’t matter what class, where it is, is all looking at this anything to do with aircraft, it’s all over this.
Nicholas Gaudern: Yeah,
Allen Hall: exactly. Or, or doing this today. It’s just wind that’s behind
Nicholas Gaudern: wind. Wind is
Allen Hall: significantly
Nicholas Gaudern: behind. No,
Allen Hall: it’s not magic. It’s proven technology. It’s
Nicholas Gaudern: just good engineering.
Allen Hall: Well, it’s good engineering and if you call PowerCurve, they’re gonna help you under to to, to understand what you have today and what you could have tomorrow.
Nicholas Gaudern: Yes.
Allen Hall: And how this, these devices will improve your revenue stream.
Nicholas Gaudern: Exactly. You know, we will look at your blades, we’ll give you some good advice and maybe that advice will be that.
You know, a certain product isn’t right for your blade. Right. That’s fine.
Allen Hall: That’s an answer.
Nicholas Gaudern: That’s an answer.
Allen Hall: Yeah, it is.
Nicholas Gaudern: But let’s, let’s look at the blade. Let’s see what’s possible, and let’s just have a, have a proper conversation about it over some real data, some real
Allen Hall: facts. Right. I think that’s the key, and a lot of operators are afraid to talk about aerodynamics is it’s, it’s a difficult area to, to start the conversation on, right?
Yeah. But I think at the end of the day, when I work with PowerCurve, and I’ve worked with you guys for a [00:23:00] number of years, the answers I get back are intelligent and they’re not. Super complicated. This is what you’re gonna see. This is the improvement. And then we can, this is how we’re going to show you can get that improvement.
It’s not magic,
Nicholas Gaudern: no
Allen Hall: power crews backing up with data, which I think is the key, right? Because you’re the, you do hear a lot of noise in this industry about magical products that’ll do all these things. Particularly aerodynamic ones. Yes. PowerCurves, the ones really bringing the data.
Nicholas Gaudern: Yeah. And we have, we have the track record now.
We have like we do 17, 1800 turbines. Should be over 2000 very soon with our products on. Yeah. So we have a lot, we have a lot of data to draw on to know that we’re doing a good thing.
Allen Hall: Well, and speaking of that, because one of the questions that always pops up is, well, we have put these new VGs or trailing edges on, are they gonna stay on?
How durable are they?
Nicholas Gaudern: Yeah. And that’s a, that’s a really important question to ask was it doesn’t matter how fancy aerodynamic product is, if it falls off the blade.
Allen Hall: Right.
Nicholas Gaudern: So, you know, we’ve spent a lot of, uh, time and effort looking at how we should be fixing these products on. [00:24:00] So we use a, uh, a wet adhesive.
We specify a plexus adhesive to put our products in place. Really good adhesive. It’s a great adhesive and it means that they are not going anywhere. Basically. It’s a very, uh, forgiving adhesive. Uh, and it’s a very high spec. So we, we don’t use, uh, sided tape. We might have some of our products for some initial tack to help, you know, get the clear, the clear outta the line exactly.
But in terms of the bond itself, that is with a, a proper structural adhesive. So one thing that we are really proud of is that we haven’t got any, uh, reported failures of our panels over all the installations we’ve made. And that’s a combination of materials, but also geometry, work, instructions, adhesive.
It’s, it’s the full package. So it’s something that, um, yes, say we’re very proud of. And I think it’s, it’s a big part of what we do at PowerCurve, making sure the product is the right shape. Sure. But also making sure it stays on the blade.
Allen Hall: Well, you see it [00:25:00] from OEMs who have all kinds of aerodynamic treatments on there, and they’ll double set a tape to the blade, and then those parts are on the ground.
Nicholas Gaudern: Yeah. And double-sided tape. You can get some really nice spec tape. Sure.
Allen Hall: You,
Nicholas Gaudern: yeah. But it’s not
a
Allen Hall: 20 year device.
Nicholas Gaudern: No. And the installation tolerance required on surface prep is really, really high. So it’s possible. It’s just harder. I think it’s riskier,
Allen Hall: it’s risky.
Nicholas Gaudern: So, you know, I think for us, the adhesive is, is the way to go.
And, and it’s been proven out by the, by the track record.
Allen Hall: And some of the things we’ve seen over in Australia is when trailing ulcerations have come off, it’s been a safety concern. So now you got
Nicholas Gaudern: absolutely
Allen Hall: government officials involved in safety because parts are coming up. Turbine.
Nicholas Gaudern: Yeah.
Allen Hall: You
Nicholas Gaudern: can’t have these components flying, flying through the air.
That’s, that’s not safe.
Allen Hall: That’s because PowerCurve has done the homework.
Nicholas Gaudern: Yes.
Allen Hall: And has the track record. That’s why you wanna choose PowerCurve. So how do people get a hold of PowerCurve? How do they get a hold of you, Nicholas, to start the process?
Nicholas Gaudern: So, um, you’re welcome to reach out to us in lots of different ways.
We’re on LinkedIn. Uh, we have our website, [00:26:00] PowerCurve, dk, um, so yeah, LinkedIn websites. There’ll probably some links on this podcast as well to get in touch. But, um, yeah, whatever way works best for you.
Allen Hall: Yeah, it’s gonna be a busy season. So if you’re interested in doing anything with PowerCurve this year, you need to get on the website, get ahold of Nicholas.
And get started, uh, because now’s the time to maximize your revenue.
Nicholas Gaudern: Thanks a lot and great to talk to you,
Allen Hall: Nicholas. Thanks so much for being back on the podcast.

Sharia Law
Does Sharia Law pose an actual threat to Americans? Are we on a path to chopping off the hands of shoplifters? Passing laws that concern what people can and cannot eat? Polygamy? Forcing women to wear the hijab?
Maybe.
Or maybe this congressman is a loudmouth asshole whose constituents are morons.

Another Thought on Tucker Carlson
Carlson’s about-face on Trump is huge, as it signals that public intellectuals who wish to be taken seriously at this point cannot support the president, as his mental condition deteriorates and his criminality becomes ever more brazen.
