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?...

  • Judge Ends Pentagon Wind Freeze, RWE Exits US Offshore

    Judge Ends Pentagon Wind Freeze, RWE Exits US Offshore
    2026/08/10
    Allen covers a judge lifting the Pentagon’s wind freeze, RWE’s $1.22B US offshore exit, and TotalEnergies buying Shell’s European renewables. Sign up now for Uptime Tech News, our weekly newsletter on all things wind technology. This episode is sponsored by Weather Guard Lightning Tech. Learn more about Weather Guard’s StrikeTape Wind Turbine LPS retrofit. Follow the show on YouTube, Linkedin and visit Weather Guard on the web. 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. You know … there is an old saying. When one door closes … another one opens. Well this week in wind energy … a whole lot of doors were swinging. Let us start in Washington. For months … the Pentagon had quietly stopped reviewing wind energy project applications. More than a hundred and fifty onshore wind projects … stuck in limbo. The Defense Department claimed that drones in Ukraine had changed the game. Wind turbines … they said … could blind radar to incoming threats. So they hit the brakes. But on Thursday … a federal judge said … not so fast. Judge Karin Immergut … a Trump appointee no less … issued a preliminary injunction. Resume the reviews … she ordered. Follow the law Congress wrote. The law gives the Pentagon seventy-five days for a preliminary review. As of late July … not a single one had been completed since the halt began in May. When government lawyers were asked to name one project they had reviewed … they could not name a single one. The judge told them plainly. If you want to change the rules … go ask Congress. Now … while one arm of the government was being told to do its job … another arm was writing checks. German energy giant RWE … handed back its American offshore wind leases. New York. California. Louisiana. In return … the U.S. Department of the Interior cut RWE a check for one-point-two-two billion dollars. RWE is the fifth developer to walk away from American offshore wind under this administration. The company had spent more than a billion dollars on those leases. Years of planning. Investment. Partnership with federal agencies. But RWE said there is simply no path forward to permit these projects … for the foreseeable future. So where does the $1.22B go? Nine hundred million dollars into Louisiana LNG. Three hundred million into natural gas turbine reservations. Fifteen gas peaking projects across the country. A company that came to America to build wind farms … is now building gas plants instead. But here is the thing about RWE. They are not leaving the wind business. They are leaving American offshore wind. Globally … RWE operates eighteen offshore wind farms. Four more under construction. And nearly seven gigawatts secured in the United Kingdom’s latest auction. America said no. The rest of the world said … come on in. And speaking of Europe … TotalEnergies … the French oil major … just bought Shell’s entire onshore renewables business in Europe. Four gigawatts of solar and wind. Five hundred megawatts already running or under construction in Italy and the Netherlands. Three-and-a-half gigawatts more in the pipeline across Italy … the United Kingdom … and Spain. And in the same breath … TotalEnergies sold a fifty percent stake in a one-point-two gigawatt European portfolio to KKR … for an enterprise value of one-point-eight billion euros. Build it. Sell half. Keep operating it. That is the model. Now let us fly east … to India. GE Vernova just landed a hundred-and-sixty-three megawatt wind order from American developer Enfinity Global. Forty-three turbines. Three-point-eight megawatts each. Headed for the Fatehgarh wind farm in Rajasthan. Deliveries start late this year. And those turbines will be built at GE Vernova’s factory in Pune … which can turn out fifteen hundred megawatts a year. India is pushing for five hundred gigawatts of renewable energy. Meanwhile … up in Denmark … a Danish wind tower maker named Welcon is raising its voice. Swedish utility Vattenfall just won two offshore wind tenders in Denmark. But when asked whether they would use European-made turbines … Vattenfall would not say. Welcon’s chief executive Jens Risvig Pedersen said … and I quote … “It would be completely absurd not to buy European products for the two new Danish offshore wind farms. That would simply shut down the European industry.” The Danish trade union Dansk Metal agreed. Chinese turbines … they said … should not be financed with Danish taxpayer money. Vattenfall says it has not decided yet. But the debate is on. And finally … a milestone that happened so quietly … nobody noticed. The world just crossed three terawatts of installed solar power. It took ten years to build the first terawatt. Less than three years for the second. And not even two more years for the third. Seventy-four countries now...

  • AC883 Joins Muehlhan Wind Service

    AC883 Joins Muehlhan Wind Service
    2026/08/13
    Lars Bendsen, founder and CEO at AC883, joins to discuss the Muehlhan Wind Service acquisition and Canada’s aging turbine fleet. The Uptime Wind Energy Podcast is brought to you by Weather Guard Lightning Tech, creators of the StrikeTape Ultra LPS retrofit. Subscribe to Uptime’s Substack newsletter. And check out Rosemary’s “Engineering with Rosie” Youtube channel. Have a question we can answer on the show? Email us! Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow. Allen Hall: Lars, welcome back to the podcast. Lars Bendsen: Thank you so much, Allen. Allen Hall: A lot has happened since I talked to you last. I saw some of the announcements on LinkedIn. I was really excited for you. So AC883 has news. Lars Bendsen: We have news. It was about a month ago now, but yes, things have been going very well. Allen Hall: Muehlhan has acquired AC883, which is a company you started how many years ago? Lars Bendsen: I started AC883 12 years ago. From my dining room table, basically. Allen Hall: Wow. And it’s grown to quite the business over time. Lars Bendsen: Yes, we have been expanding, especially the last five years after my son came in. He has been the main driver, so we’ve been expanding like crazy the last five years. And, well, getting older. Now we are at a point where we should extend, spend more. And then when Muehlhan, one of the biggest companies in the wind industry, looked our way, it was an easy decision to make. Very easy. Allen Hall: Muehlhan is well known for being a leader in the ISP world in Europe, and a little bit in America. They’re still making a presence here. That’s why they wanted to talk to you, I’m sure, because AC883 has a nice Canadian market. People trust you and rely upon you, because you bring the quality people over, plus you have all the resources to get to parts that you can’t acquire in Canada and the United States. You know who to call. It’s part of that Danish connection. And that makes a lot of sense, because I do think as we see the industry mature, those quality companies like AC883 are very valuable. They see them as being a huge resource to the industry. Lars Bendsen: As I said, it makes us really proud that a big company is looking our way, and it’s been a very smooth transition. As you were talking about earlier, the industry is maturing, meaning also big is getting bigger, and you need more horsepower, you need more muscle. And we also needed that, because we’re expanding and there’s only so much we can do. And we’re all getting older, so at a certain time you have to do something. Allen Hall: Sure, but it comes at a point where you’ve proven yourself time and time again. How many times have you grown an industry in your lifetime? You’ve done it many, many times. That’s why AC883 has always been the relied-upon source for so many things. Now Muehlhan brings a lot of advantages and a lot of horsepower to the organization. Because as you have gotten larger, you realize there’s a lot of back office things that need to happen. Safety, gear, equipment. It’s not just putting technicians on ropes out on site. There’s all the management of that. That’s where size matters. Lars Bendsen: Size matters, and also the whole health and safety perspective. You’re putting more staff behind the scenes than actually in front of the scenes. So it’s also extremely expensive. And now we’re expanding our offering, because under the Muehlhan umbrella we can do everything, including main component changes, which we didn’t do before. We decided before that anything we need a crane for, we do not do. Allen Hall: Right, I remember that. Lars Bendsen: Because it’s a completely different animal from a health and safety perspective, equipment, et cetera. And now in Canada, the company we’re going to be merging with, that’s what they do. They’re really strong in lifting and really strong in installation of turbines, complete wind farms. Where we are strong on the O&M side. And our primary customer is the asset owners. Allen Hall: Asset owners love you. Lars Bendsen: We hope so. We think so. Allen Hall: I know they do. Lars Bendsen: Where the other company is more focused on the OEM side. So there’s actually a really good mix in that. And we don’t step on each other’s toes, because we are focused on the O&M part and they’re focused on installation of turbines. So it’s a perfect match in so many ways. Allen Hall: And particularly in Canada, because the Canadian market is poised to put a lot of turbines up in the next couple of years. But at the same time, there’s an older fleet there, and spare parts is an issue. Some of the blades and the repairs are a little more complicated just because of the age of the turbine. And there are a lot of spares and components that you have access to and can bring into the Canadian market. You keep those turbines that ...
