Plus answers to other pressing questions about the offshore wind project.
The blade that snapped off an offshore turbine at the Vineyard Wind project in Massachusetts on July 13 broke due to a manufacturing defect, according to GE Vernova, the turbine maker and installer.
During GE’s second quarter earnings call on Wednesday, CEO Scott Strazik and Vice President of Investor Relations Michael Lapides said there was no indication of a design flaw in the blade. Rather, the company has identified a “material deviation” at one of its factories in Gaspé, Canada.
“Because of that, we're going to use our existing data and re-inspect all of the blades that we have made for offshore wind,” Strazik told investors, adding that the factory has produced about 150 blades total.
Company executives shared more details about their findings at a public meeting in Nantucket on Wednesday night. Roger Martella, GE Vernova’s chief sustainability officer, said there were two issues at play. The first was the manufacturing issue — basically, the adhesives applied to the blade to hold it together did not do their job. The second was quality control. “The inspection that should have caught this did not,” he said. “So it’s a combination of the two factors.”
Two dozen turbines have been installed as part of the Vineyard Wind project so far, with 72 blades total. GE Vernova has not responded to requests for clarification about how many of them originated at the Gaspé facility.
The re-inspection process does not involve physically inspecting each blade, Martella explained. The company takes “incredibly detailed ultrasound pictures” of every blade it produces, he said, and will be reviewing the images as “a desktop exercise.” He likened the process to getting a second, more detailed opinion from a doctor on an MRI. When asked why the company did not catch the defect the first time these scans were inspected, Martella said answering that is part of the ongoing investigation. In the meantime, blade production at the factory is on pause.
GE also stressed that the incident at Vineyard Wind was unrelated to a blade failure at the Dogger Bank wind farm in the U.K. earlier this year, which was due to an installation error. Installation has resumed at Dogger Bank.
Tensions were high at Wednesday night’s meeting, where Nantucket residents again lined up to lambast Vineyard Wind. Select Board chair Brooke Mohr opened the meeting by saying that the incident has shown the inadequacy of the Good Neighbor Agreement, a settlement between the town and Vineyard Wind reached in 2020. Under the agreement, the company would contribute $4 million to a community fund and take steps to minimize visual impacts of the wind farm. In return, the town would “convey support” for the project to the community and to state and federal officials. Mohr said the town now intends to renegotiate these terms. “The Select Board is committed to holding vineyard wind and GE, the manufacturer of the turbine blades, accountable,” she said.
Town representatives are going to meet with Vineyard Wind next week to negotiate compensation for the costs it has incurred as a result of the accident.
Meanwhile, on the ground and in the water around Nantucket, crews from Vineyard Wind and GE continued to collect blade debris on Wednesday morning, for the ninth day straight. An initial environmental assessment of the blade debris published late Tuesday night began to answer key questions about the risks all that debris poses to people and marine life.
The report was commissioned by GE and conducted by Arcadis US, an engineering and environmental consultancy. It asserts that the primary risk to people is injury from the sharp edges of fiberglass fragments and that the debris “are considered inert, non-soluble, stable, and nontoxic.”
It also cautions, however, that further evaluation will be required to understand the risks posed by any blade materials that remain in the environment, such as assessing the potential for degradation. At the meeting in Nantucket on Wednesday night, one resident asked whether they should be worried about eating fish or shellfish that may have ingested pieces of the blade. Jim Nuss, one of the authors of the Arcadis report, said the firm had “not considered that yet,” and that it would be “one of the future looking activities.”
One particularly concerning question has been whether the debris could discharge dangerous per- and polyfluoroalkyl substances, also known as PFAS or “forever chemicals,” into the environment. Though there are no PFAS used in the blade construction itself, the firm did identify the chemicals in “aerodynamic add-ons,” small 6 inch by 8 inch pieces of plastic that are installed on the outside of the blade to improve its efficiency that are also commonly used on airplanes, it said.
According to the report, the total amount of PFAS on one blade equals 28.2 grams, or about 0.06 pounds. To put that in perspective, the chemical company Daikin once estimated it would release roughly 200 pounds of PFAS per day into the wastewater at one of its paper mills, according to federal filings obtained by the Environmental Defense Fund in 2018. It’s not yet clear how many of those plastic “add-ons” made it into the ocean.
A comprehensive list of all materials that make up the blades shows that more than half, by weight, is fiberglass. The other key ingredients include carbon fiber and PET foam, a common construction material. “There are 33 different materials involved in the production of a turbine blade, from the most basic common household adhesives to the more complex industrial materials used to build the blade,” the report says.
An introduction to the report notes that GE is creating an inventory of the debris collected to assess how much of the blade has been recovered. The company has also hired Resolve Marine, a marine salvage firm, to aid in dismantling the remainder of the blade that’s still attached to the turbine, though it didn’t offer a timeline for this work.

The Trump administration just did something surprising: It paved the way for a transmission line to a solar energy project.
On Friday, the Bureau of Land Management approved the Gen-Tie transmission line and associated facilities for the Sapphire Solar project, a solar farm sited on private lands in Riverside County, California, that will provide an estimated 117 megawatts to the Southern California Public Power Authority.
It is the first sign so far that some renewable energy requiring federal lands may be allowed to develop during the next four years, and is an about-face from the first weeks of Trump’s presidency.
BLM notably said the solar project’s transmission line will help “Unleash American Energy” (the bureau’s capitalization, not mine). And it said the move “aligns with” Trump’s executive order declaring a national energy emergency — which discussed only fossil fuels, nuclear, and hydropower — because it was “supporting the integrity of the electric grid while creating jobs and economic prosperity for Americans.”
“The Bureau of Land Management supports American Energy Dominance that prioritizes needs of American families and businesses,” BLM California State Director Joe Stout said in a statement provided via press release.
Another executive order Trump issued on his first day back in office paused solar and wind project permitting for at least 60 days, leading to a halt on government activities required to construct and operate renewable energy projects. It’s unclear whether these actions to move Sapphire’s transmission line through agency review means the federal permitting pipes are finally unstuck for the solar industry, or if this is an exception to the rule — especially because the pause Trump ordered has yet to hit the expiration date he set on the calendar.
For those keeping score, that’s three more than wanted to preserve them last year.
Those who drew hope from the letter 18 House Republicans sent to Speaker Mike Johnson last August calling for the preservation of energy tax credits under the Inflation Reduction Act must be jubilant this morning. On Sunday, 21 House Republicans sent a similar letter to House Ways and Means Chairman Jason Smith. Those with sharp eyes will have noticed: That’s three more people than signed the letter last time, indicating that this is a coalition with teeth.
As Heatmap reported in the aftermath of November’s election, four of the original signatories were out of a job as of January, meaning that the new letter features a total of seven new recruits. So who are they?
The new letter is different from the old one in a few key ways. First, it mentions neither the Inflation Reduction Act nor its slightly older cousin, the Infrastructure Investment and Jobs Act, by name. Instead, it emphasizes “the importance of prioritizing energy affordability for American families and keeping on our current path to energy dominance amid efforts to repeal or reform current energy tax credits.” The letter also advocates for an “all-of-the-above” approach to energy development that has long been popular among conservatives but has seemed to fall out of vogue under Trump 2.0.
Lastly, while the new letter repeats the previous version’s emphasis on policy stability for businesses, it adds a new plea on behalf of ratepayers. “As our conference works to make energy prices more affordable, tax reforms that would raise energy costs for hard working Americans would be contrary to this goal,” it reads. “Further, affordable and abundant energy will be critical as the President works to onshore domestic manufacturing, supply chains, and good paying jobs, particularly in Republican run states due to their business-friendly environments. Pro-energy growth policies will directly support these objectives.”
As my colleagues Robinson Meyer and Emily Pontecorvo have written, tariffs on Canadian fuel would raise energy prices in markets across the U.S. That includes some particularly swingy states, e.g. Michigan, which perhaps explains Rep. James’ seeming about-face.
Republicans’ House majority currently stands at all of four votes, so although 21 members might not be huge on the scale of the full House, they still represent a significant problem for Speaker Johnson.
Editor’s note: This story has been updated to reflect the fact that Rep. James did not unseat Democrat Carl Marlinga in 2022 as the district had been newly created following the 2020 census.
Three companies are joining forces to add at least a gigawatt of new generation by 2029. The question is whether they can actually do it.
Two of the biggest electricity markets in the country — the 13-state PJM Interconnection, which spans the Mid-Atlantic and the Midwest, and ERCOT, which covers nearly all of Texas — want more natural gas. Both are projecting immense increases in electricity demand thanks to data centers and electrification. And both have had bouts of market weirdness and dysfunction, with ERCOT experiencing spiky prices and even blackouts during extreme weather and PJM making enormous payouts largely to gas and coal operators to lock in their “capacity,” i.e. their ability to provide power when most needed.
Now a trio of companies, including the independent power producer NRG, the turbine manufacturer GE Vernova, and a subsidiary of the construction firm Kiewit Corporation, are teaming up with a plan to bring gas-powered plants to PJM and ERCOT, the companies announced today.
The three companies said that the new joint venture “will work to advance four projects totaling over 5 gigawatts” of natural gas combined cycle plants to the two power markets, with over a gigawatt coming by 2029. The companies said that they could eventually build 10 to 15 gigawatts “and expand to other areas across the U.S.”
So far, PJM and Texas’ call for new gas has been more widely heard than answered. The power producer Calpine said last year that it would look into developing more gas in PJM, but actual investment announcements have been scarce, although at least one gas plant scheduled to close has said it would stay open.
So far, across the country, planned new additions to the grid are still overwhelmingly solar and battery storage, according to the Energy Information Administration, whose data shows some 63 gigawatts of planned capacity scheduled to be added this year, with more than half being solar and over 80% being storage.
Texas established a fund in 2023 to provide low-cost loans to new gas plants, but has had trouble finding viable projects. Engie pulled an 885 megawatt project from the program earlier this week, citing “equipment procurement constraints” and delays.
But PJM is working actively with a friendly administration in Washington to bring more natural gas to its grid. The Federal Energy Regulatory Commission recently blessed a PJM plan to accelerate interconnection approvals for large generators — largely natural gas — so that it can bring them online more quickly.
But many developers and large power consumers are less than optimistic about the ability to bring new natural gas onto the grid at a pace that will keep up with demand growth, and are instead looking at “behind-the-meter” approaches to meet rising energy needs, especially from data centers. The asset manager Fortress said earlier this year that it had acquired 850 megawatts of generation capacity from APR Energy and formed a new company, fittingly named New APR Energy, which said this week that it was “deploying four mobile gas turbines providing 100MW+ of dedicated behind-the-meter power to a major U.S.-based AI hyperscaler.”
And all gas developers, whether they’re building on the grid or behind-the-meter, have to get their hands on turbines, which are in short supply. The NRG consortium called this out specifically, noting that it had secured the rights to two 7HA gas turbines by 2029. These kinds of announcements of agreements for specific turbines have become standard for companies showing their seriousness about gas development. When Chevron announced a joint venture with GE Vernova for co-located gas plants for data centers, it also noted that it had a reservation agreement for seven 7HA turbines. But until these turbines are made and installed, these announcements may all just be spin.
