Allen Hall: Welcome to the Uptime Wind Energy Podcast. I’m your host, Allen Hall here with Nikki Briggs, who is in North Carolina this week, and Yolanda Padron who is back from the exciting wedding and weekend in Mexico. Welcome back, Yolanda. Yolanda Padron: Thank you. Excited to be here, Allen Hall: uh, this week there’s a, there’s a lot going on and we’re gonna touch upon some of it. Uh, Rosemary is over in China this week and Matthew is actually at Wind Europe in Madrid. And so this is gonna be an American focused episode mostly, but it’s gonna have global implications. One of the key items is PPA prices in the United States and with the on sunsetting of the [00:01:00] IRA Bills, uh, tax credits, and the whole infrastructure there with the one big beautiful bill when it crushed the IRA bill. PPA Prices needed to come up well. That’s happening, right? So developers, uh, can’t live without some money to compensate for the roughly 26, 26 7 20 $7 in PPA prices that were compensated by the tax credits. But, uh, when purchase price agreements have hit the highest level since they begin tracking it at Wood Mac. The average wind PPA now stands at $79 and 40 cents per megawatt hour up 24% from just one year ago now, Yolanda, you and I were talking before we started recording today about how low some of those PPA prices were two years ago, three years ago. Some of them were almost single digits. Yolanda Padron: Yeah, yeah. Some of them were pretty low. I [00:02:00] remember 16, $19 EPA prices and then a couple years ago we were looking at those and thinking, oh no, I can’t believe we, we kept those prices and they’re so low and everything’s changed so much, and the prices grown so much, and that was two years ago and now it’s, it’s, it’s, it’s almost four times as much as, as what we had originally thought, which is. Not super great for those older projects, Allen Hall: obviously, uh, when they, if they do repower, the extent they’re gonna have to renegotiate the PPAs. Right. The, the landscape has changed quite a bit. So the, the question really is now are they gonna be able to renegotiate new PPAs when the existing PPA hopefully ends? You can’t, you can’t run turbines for free and will they repower. Or will they just try to extend the lifetime? I think it’s a lot of operators trying to figure that out right now. And that’s in light of installations. So Whim Mac also says that US wind installations are [00:03:00] on track to nearly double in 2026, uh, building towards 48 gigawatts of new capacity through 2030, which all makes sense, right? That the, the. Uh, everybody’s trying to get all their assets in the ground so they, they qualify for the, the tax credits. So there’s a big push. So 2026 and 2027 are gonna be pretty busy years. Uh, but the, the negotiations are still going on and we’re talking to operators. Nikki and I have been talking to operators this past week or the last couple of weeks, honestly. There is all kinds of negotiations going on for turbines right now and who can get turbines? Can they get ’em in time? Can they get ’em planted fast enough? Nikki, it is causing a lot of operators to spend a great deal of time doing planning that they otherwise wouldn’t have been working on two years ago. Nikki Briggs: Definitely. I mean, it seems kind of weird to me because it’s like a weird spot. It’s like, um, you know, we want more power and we need to do all these projects, [00:04:00] but then. The permitting process is just like a brick wall or something, you know? Um, like it just takes them so much more to get through, um, and get it moving. Allen Hall: Well, I, I think if you have an existing site, you’re gonna repower it. I mean, that’s probably the easiest thing to do if, if you can pull it off. The, the question is how big of a turbine are you gonna purchase? A lot of those turbines that are gonna get repowered are probably 1.5. To two megawatt machines. They’re going to move up to five or six megawatt machines, generally speaking. So they’re reducing the amount of turbines that are gonna be on site. But the, the amount of power that...

  • WindEurope Demands Action, Siemens Gamesa Closes In on Break-Even

    WindEurope Demands Action, Siemens Gamesa Closes In on Break-Even

And subscribe to Rosemary’s “Engineering with Rosie” YouTube channel here. Have a question we can answer on the show? Email us! Good Monday, everyone. This past week… some big things happened in Madrid. Fifteen thousand wind energy people from every corner of the world walked into the same room. They came to talk. They came to listen. They came to ask for help. And they came to warn. The WindEurope Annual Event opened on Tuesday, the twenty-first of April, with six hundred twenty exhibitors and four hundred speakers across three days. Spain’s Prime Minister Pedro Sanchez gave the opening address. Fourteen national ministers stood on the stages, alongside European Commission Executive Vice President Teresa Ribera and European Commissioner for Energy Dan Jorgensen. And the message coming out of Madrid… was a single piece of paper. They called it the Madrid Call to Action. Ten points. Ten things European governments need to do… right now. Fast-track permitting, and treat wind as overriding public interest. Award at least eighty percent of wind auction bids… no more artificial scarcity. Repower aging wind farms and triple their output with fewer turbines. Multiply EU grid funding by five. Zero VAT on heat pumps and electric vehicles. And permanently cut taxes on electricity… because homegrown power should be the cheapest power. The framing was simple. From crisis… to confidence… in a decade. But while the speeches were polite… the panels were not. On Thursday afternoon, Vestas chief executive Henrik Andersen took the microphone, and he did not mince words. Andersen called it mission impossible. He told politicians to stop submitting wish lists for new auctions. He pointed at Denmark’s recent failed offshore auction… an auction that no developer would even bid on. And he pointed at countries trying to build a three-dimensional CSRD into the next tender. Then he delivered the line that quieted the room. If we don’t get this under control… we’ll be sitting here in five years… begging to keep the lights on. Now… while the warnings were echoing through Madrid… something quieter was happening on a balance sheet in Munich. Siemens Energy released preliminary second-quarter results on Wednesday, and then raised their full-year outlook. Group orders for the quarter came in at seventeen point seven billion euros… up almost thirty percent year on year. Net income for the full year is now expected to be around four billion euros, with Grid Technologies orders alone up forty-one percent. And the wind unit… Siemens Gamesa… their losses narrowed to forty-four million euros. A year ago, that number was two hundred forty-nine million. Still in the red. Still operating at a margin of negative one point seven percent. But the trend is clear. The Spanish wind unit is closing in on break-even. After years of crisis… after billions of euros in impairments… Siemens Gamesa is healing. Now back to Madrid. Because last Thursday, WindEurope published a different kind of paper. Not about money. Not about megawatts. About sabotage. Across Europe’s seas, energy infrastructure has become a target. Cables, substations, offshore platforms… spread across thousands of square kilometers of open ocean… difficult to protect. WindEurope Chief Executive Tinne Van Der Straeten said it plainly. The physical security of Europe’s wind turbines must be treated as an integral part of energy security… not as an afterthought. The policy paper calls for civilian protection, not military. Risk-based and proportionate, with clear cost allocation between government and industry. Wind farms now generate twenty percent of Europe’s electricity, and the North Sea countries have pledged three hundred gigawatts of offshore wind by twenty fifty. That is a lot of critical infrastructure… sitting in the open ocean. But here is where Madrid got uncomfortable. Vestas’ senior vice president stood on a panel Wednesday afternoon and offered a reality check. The EU has set a goal of twenty-two gigawatts of new wind installation every year through twenty thirty. What is the reality? The EU installed fifteen gigawatts in twenty twenty-five. Sixteen the year before. There is a gap… between political will, goals, and promises… and the reality we see in the market. The Madrid Call to Action wants to close that gap. The paper exists. The politicians have been told. Now… we wait. And while the speeches were happening in Madrid… a...

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 ...
