Eight hundred million dollars. That is what tariffs on steel and aluminum added to Dominion Energy’s Coastal Virginia Offshore Wind project. Dominion President Bob Blue shared the damage on a second-quarter earnings call. Two hundred and thirty million dollars … just in the latest quarter alone. That is on top of the five hundred and eighty million from the quarter before. The project is eighty-one percent complete. Thirty-one turbines are already spinning … producing more than four hundred and fifty megawatts. But the finish line just moved. Completion is now expected by the end of twenty twenty-seven. Weather delays. Vessel maintenance. And some particularly complicated turbines to install. Blue says the project will still save customers money. And Dominion expects to pocket more than five hundred million dollars in savings from grid upgrade cost shifts. The total price tag … eleven-point-six billion dollars. Now … if Dominion is feeling the squeeze in Virginia … Eversource up in New England is feeling something worse. The utility’s second-quarter profit dropped eighty-four percent. Net income fell to just fifty-three-point-seven million dollars. Why? A one-hundred-and-sixty-four-million-dollar charge tied to the offshore wind projects they already sold. South Fork Wind. Revolution Wind. Eversource got out of offshore wind back in twenty twenty-four … but the bills keep coming. Higher-than-expected payments to Global Infrastructure Partners are dragging down the bottom line. So one company builds through the pain. Another walks away … and still pays for it. But here is some good news. Over in Hamburg, Germany … Nordex just posted a quarter that would make any CEO smile. Sales up sixteen percent. EBITDA … more than doubled … to two hundred and twenty-four million euros. Margins hit ten-point-three percent. Net income … one hundred and eleven million euros. Up from thirty-one million a year ago. And orders? Up thirty-two percent. Three-point-one gigawatts of new turbine orders in just one quarter. Their total order book now stands at eighteen-point-four billion euros. Nordex CEO José Luis Blanco confirmed the full-year guidance. The onshore wind giant is not just surviving. It is thriving. Now … let us go to sea. Classification society ABS says floating offshore wind is about to create a brand-new problem. Not enough ships. A new report says demand for large anchor-handling vessels and multipurpose support vessels will surge as floating wind projects go from small demonstrations to full commercial scale. Here is the number that tells the story. A single one-gigawatt floating wind farm needs about one hundred and ninety-eight anchors … and nearly two hundred kilometers of mooring lines. That is far more than a single deepwater oil and gas platform. ABS says shortages in certain vessel classes could hit as early as twenty twenty-nine. Global floating wind capacity is expected to grow from about two hundred and seventy megawatts today … to fourteen gigawatts by twenty forty. The race for ships … has begun. And speaking of ships … Japan just finished building one. Mitsui O.S.K. Lines held a naming ceremony in Nagasaki for the Wind Whale. Japan’s first coastal deck carrier built specifically for offshore wind. One hundred and forty-nine meters long. A flush deck designed so that monopiles, towers, blades and nacelles can roll right on from the stern. It even has dynamic positioning … so it can transfer cargo directly to installation vessels at sea. Built in China by Taizhou Sanfu Ship Engineering … the Wind Whale will carry foundations from a factory in Okayama to construction sites around Japan. A country that once built ships for oil … now builds them for wind. And finally … back home in Iowa. The state Supreme Court ruled that the CEO of Global Fiberglass Solutions can be held personally liable for dumping thirteen hundred used wind turbine blades across the state. CEO Donald Lilly and another executive argued they were never in Iowa. The court disagreed. Lilly signed the contracts. Iowa Attorney General Brenna Bird put it plainly. They were hired to recycle used wind turbine blades. Instead … they dumped them. Four hundred blades piled up along Interstate 35 near Ellsworth alone. The lesson? You can build an industry on ...

  • Blade Breaks at He Dreiht, Suzlon Posts Record Quarter

Protecting thousands of wind turbines from lightning damage worldwide. Visit striketape.com. And now your hosts Allen Hall: Welcome to the “Uptime Wind Energy” podcast. I’m your host, Allen Hall, and I’m here with Matthew Stead, Yolanda Padron, and Rosemary Barnes. And to lead off this week, s- there’s been some trouble in the North Sea. On July 22nd, a blade failed on one of the turbines at EnBW’s 960-megawatt He Dreiht offshore wind farm. Uh, EnBW spokesperson said there were no injuries, thank goodness, and that the authorities were notified immediately, which is generally the case in Europe. They’re very safety conscious, of course. But the machine was a Vestas V236, which is a– that 15-megawatt offshore turbine that Vestas is offering. And He Dreiht is where the platform [00:01:00] has made its debut. So Vestas and EnBW are working together on an investigation, an RCA, a- along, uh, looking at the environmental impact because parts of the blade landed in the water. And the, the images I saw online were like a sheer web that was being pulled in onto a ship, so big pieces of blade. Uh, there’s gonna be 64 of these turbines going into that wind farm, but this is probably a little bit of a weird thing because it does seem like that the wind farm is under construction when the blade broke, which is not the first time this has happened, right? That we’ve seen blade breaks at, uh, Vineyard Wind and at Dogger Bank on the GE side. Is this just a construction issue, Yolanda, you think? Or is it some sort of, uh, vibration that’s happening during construction that’s putting extra stress on the blades? Yolanda Padron: We were talking about it a little bit offline and how it might be a loading [00:02:00] issue because it’s not, uh, it’s not in the optimal operating, uh, conditions, right? Uh, but this is– It’s– I don’t like that it’s becoming a trend more than an anomaly from what we’ve seen on this podcast. Uh, Matt, I know you work a lot in solutions, right? What, what would you recommend people start doing? Matthew Stead: Yeah. I think, um, more and more there’s ways of just checking out, you know, pre-construction, um, you know, some of the vibration modes, some of the unusual, um, wind loading when it’s in standstill, you know, different yaw angles and so forth. So there, there’s more and more ways of, um, checking out what the blade is doing when it’s in those unusual, um, sort of pre-con, pre-operation phases. So, um, you know, for instance, um, we do know that there is some sort of sometimes edgewise or flatwise vibration, which, um, you know, maybe is not normal, um, and maybe could be, be [00:03:00] thought about in a bit more detail. Um, certainly I know there are some research organizations which are looking into this and also, you know, things like blade twists. Um, so what is actually happening in terms of the, um, the twisting of the blade along, along its axis. Allen Hall: I think the last time this happened, I remember going back and looking at patents about how to protect the blades during this construction phase. So you wanna prevent the blade from generating lift from sideways winds pretty much. So the designs that I saw were like putting like a, a netting across the blade to disrupt the airflow so that it wouldn’t generate lift. But I haven’t really seen that implemented. Maybe it is being implemented, but these loads are a little odd, right? I, I, I’m wondering if there’s any IEC certification test that looks into them, uh, just because it’s, it’s happened a couple of times now, more than a handful. Matthew Stead: We, we saw, um, we saw that picture of some blades on the ground. [00:04:00] You remember they were in storage. Um, there was a, a strong wind that came across them when they were in storage, and there was some, some flutter and, you know, some, some damage it caused, uh, even when they were on the ground. Um, yeah, I think just thinking out loud, you know how on some, you know, wind stacks and, or, you know, turbine stacks and, um, you know, poles, you know, exhaust stacks. Sorry, that’s the word I’m looking for. Exhaust stacks. They have the, the spiral around it. You know, it’s for around vortex shedding. So maybe it’s an opportunity for, for Rosie to ...

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow Allen Hall: Jon, welcome back to the program. Jon Zalar: Thanks for having me. Allen Hall: Uh, last time I saw you, we were in Melbourne- Yep … at WOMA 2026, and that was a huge event. We know we’re gonna do it again next year in March three, the 3rd through the 5th, so you’re invited back, of course- I can’t wait … if you can make it. Yeah. Yeah. It’s gonna be, it’s gonna be a good time. A lot is happening in the blade world and in the wind turbine world more broadly. A lot of things we’re hearing right now are related to blade bolt connection, pitch bearing inserts still. A lot of that still happening in the United States. What is the current status of, uh, the blade connection issues in the US? I, Jon Zalar: I feel like it’s a growing [00:01:00] issue, not super, super fast, but it seems to be getting a little worse. There’s, you know, more bolts breaking at that joint. Um, pitch bearing cracks are, seem to be pretty common. There’s different solutions for it, and then, you know, the root inserts are another thing that we’ve talked about before that seem to be happening more and more, or maybe more and more people are finding them ’cause they’re looking. Allen Hall: What are the first indications that you have a blade bolt or some sort of joint issue at the root of a blade? What can you see? Jon Zalar: A bolt laying in the hub bouncing around. Um, you know, from like a– looking at it from, like, the sensors on the turbine, it’s really hard to tell unless it gets really bad. Uh, some of the OEMs have some analytics developed to kinda start to indicate if there is a aero change because there’s missing bolts or root inserts are coming out, and they’re using that as a way to go figure out which ones to go inspect first. Allen Hall: Really? Yeah. You think [00:02:00] the SCADA data will give you some indication that you have a, basically a little bit of a loose blade? Jon Zalar: Yeah. I, I, I think because the number of turbines and the number of data points you have, I think there is a pretty good analytic out there right now. Allen Hall: Wow. All right. I think a lot of our operators have not taken advantage of that. Is, is that just b- based on the high-speed data, SCADA data, or is it low-speed data you could see that same effect? Jon Zalar: I believe it’s on the low-speed data as well, but I bet the high-speed data was used to kinda develop it. Allen Hall: Wow. All right. So that’s a huge help to operators. Yeah. So what are you looking for if you’re looking through SCADA data, what would be the couple of markers there that say, “Hey, maybe we ought to go look up at the– in the hub”? Jon Zalar: I don’t know exactly what they’re using, but they would basically look for maybe an imbalance or looking for certain components that are being overworked. Allen Hall: Oh, sure. Okay. Jon Zalar: Yeah. Allen Hall: So your pitch actuator may be getting a little bit overworked. It would seem like one of the places- I think that, yeah … that would get loaded, right? Jon Zalar: Mm-hmm. Allen Hall: Okay. [00:03:00] And any vibration monitoring going on? Because it, it, uh, in some cases you’re– I’m hearing, like, millimeter gaps- Jon Zalar: Correct. Yeah … Allen Hall: between the blade and the pitch bearing. Jon Zalar: So probably a combination of the ALC sensors, at least on a GE turbine, looking at that. But the PCH box also is looking at the tower vibration, so it could be a combination of all three. I don’t know the exact- Okay … details, but between all of that, I think there are some analytics that kinda say, “Hey, go take a look.” And then I think there’s some other companies that have- tools that go monitor it. Allen Hall: Mm-hmm. Jon Zalar: Dial indicators remotely or even, you know, people going up there with dial indicators to go kind of rotate the rotor and kind of see if there is gapping between the blade and the pitch bearing. Allen Hall: Is that a safe situation in your– from the gapping? I’ve heard this where they’ve basically took shims and they’re trying to measure this gap or some sort of dial indication. Is that a smart thing to do? Is it even reliable to do it that way?...
