Construction on Vineyard Wind 1 and Revolution Wind has been paused as of Monday. —Jennette Barnes CAI

Updated Jan. 6

The administration of President Donald Trump halted work on all large-scale offshore wind projects under construction, effectively torpedoing any progress in this sector of the renewable energy industry. It is the latest battle in Trump’s declaration of war on offshore wind, which began on his first day in office.

The suspension was issued Monday, Dec. 22, on two fully permitted projects visible off the coast of Martha’s Vineyard — Vineyard Wind 1, which is already largely up and running, and Revolution Wind, which is close to completion. Both projects are likely to be suspended for at least the next three months.

The pause, made effective immediately, is attributed to publicly undisclosed national security concerns identified in classified reports by the Department of Defense, which the administration now refers to as the Department of War. Trump’s suspension not only potentially forces stakeholders to continue to battle the federal government in court, but also further delays benefits promised to the Island, including jobs and funds for onshore energy projects.

Revolution Wind, 12 miles off of Aquinnah, and Vineyard Wind 1, 15 miles south of the Island, were both nearly completed, and the latter was already delivering power to the grid. But now, this halt places the array of turbines off the coast of Island at the center of what has become a titanic struggle, fought repeatedly in the courts, between supporters of renewable energy and the Trump administration, which has always opposed wind. 

The Vineyard Wind 1 offshore wind farm, which survived most of the year unscathed by a bombardment of stop-work orders and the threat of permit reconsiderations seen by other projects by the federal government, is now in the line of fire. Meanwhile, Revolution Wind was here not too long ago; the 65-turbine project was forced to halt construction in late August, and was only allowed to resume a month later when a federal judge granted a stay and injunction on the order.

“The prime duty of the United States government is to protect the American people,” Secretary of the Interior Doug Burgum said in the release Monday. “Today’s action addresses emerging national security risks, including the rapid evolution of the relevant adversary technologies, and the vulnerabilities created by large-scale offshore wind projects with proximity near our East Coast population centers. The Trump administration will always prioritize the security of the American people.”

Burgum also posted on his X account, “Due to national security concerns identified by @DeptofWar, @Interior is PAUSING leases for 5 expensive, unreliable, heavily subsidized offshore wind farms! ONE natural gas pipeline supplies as much energy as these 5 projects COMBINED. @POTUS is bringing common sense back to energy policy & putting security FIRST!”

Gov. Maura Healey fired back on the announcement, establishing battle lines between the Trump administration and a liberal establishment that believes in the benefits of renewable energy for jobs, the environment, and lower electricity rates. 

“Energy costs are already too high. It makes absolutely no sense for the Trump Administration to halt construction on a project that is bringing more affordable energy to our region. This puts people out of work during the holidays,” said Healey in a statement. 

Healey added, “Vineyard Wind has been producing power for a year, bringing down costs for residents and businesses, while creating nearly 4,000 jobs right here in Massachusetts. Donald Trump should be embracing an all-of-the-above approach to American energy, not shutting down critical sources like wind. It is dangerous to halt construction in the middle of a project, and I will stand up against this unlawful action by the Trump Administration to protect Massachusetts’ ratepayers and workers. We are working closely with impacted states and developers to ensure the projects are completed and continue to provide affordable power to our communities.”

There was no timeline for the suspension specified by the federal government, but Ørsted, part owner of the Revolution Wind project, said they received orders from the Department of the Interior’s Bureau of Ocean Energy Management (BOEM) to suspend all activities on the outer continental shelf for 90 days, a timeline that Ørsted officials also said was subject to an extension. Vineyard Wind 1 officials didn’t respond for comment.

A press release from the Interior said that the pause will allow federal agencies to “work with leaseholders and state partners to assess the possibility of mitigating the national security risks posed by these projects.”

Ørsted also owns Sunrise Wind, another wind farm south of the Vineyard and paused by the federal government. Empire Wind 1, a project off the coast of New York by the Norwegian energy company Equinor, was also included and, like Revolution Wind, was already issued a stop-work order this year, lifted a month later. Coastal Virginia Offshore Wind, by U.S.-based Dominion Energy off the coast of Virginia, was also suspended Dec. 22.

“Revolution Wind LLC and Sunrise Wind LLC are complying with the respective orders and are taking appropriate steps to suspend related activities in a manner that prevents impacts on health, safety, and the environment,” a press release from Ørsted said. “Ørsted is evaluating all options to resolve the matter expeditiously, together with its partners. This includes engagement with BOEM and other permitting agencies as well as the evaluation of potential legal proceedings.”

Ørsted officials also noted that both projects were set to deliver power in 2026. Revolution Wind was expected to generate power as soon as January to Rhode Island and Connecticut.

ISO–New England, a nonprofit corporation that manages the grid for the six New England states, said Vineyard Wind 1 and Revolution Wind are included in near-term and future models for electricity demand, and are especially important in the winter, when ocean winds are strongest and steadiest, and output from offshore wind is the highest. The nonprofit forecasts enough power for the current season, but added that “canceling or delaying these projects will increase costs and risks to reliability in our region.”

The national security concerns in the classified reports aren’t spelled out, but the press release references previous unclassified reports that say the movement of the turbine blades and reflective towers cause radar interference called “clutter,” which can obscure objects and create false ones within the wind projects.

Officials from Ørsted said that as part of a review of their two projects, they “consulted closely and directly with the U.S. Department of Defense Military Aviation and Installation Assurance Siting Clearinghouse to evaluate and address potential impacts to national security and defense capabilities from construction and operation.”

They’ve also already fought a stop-work order that cited the “protection of national security interests.” This was previously used by the federal government to halt construction on Revolution Wind on Aug. 22, though the developer, who took the matter to court, said the claim lacked any evidentiary basis. An injunction was granted on that order by a federal judge a month later, and construction resumed.

Kate Sinding Daly, senior vice president for law and policy at the Conservation Law Foundation, said that the basis for these new pauses is “some newly uncovered national security concerns” that are in classified reports, and so the process to challenge them is much more complex. “It’s another sneaky tactic,” she said.

She also said that litigation is inevitable, and hopes that developers and states take the matter to court, as was successfully done before. It also remains unclear whether or not Vineyard Wind 1 can continue to send power to the grid, but Sinding Daly said that should the developers decide to go to court, that is what will need clarity.

Fred Khedouri, who is the owner of Martha Rose Fisheries and member of the zoning board of appeals and Land Bank commissioner in Chilmark, previously worked in the White House under Ronald Reagan as associate director for natural resources, energy, and science at the Office of Management and Budget and said national security is the hardest thing to challenge. He added that he has experienced radar interference out on the water. “And while it is scary and definitely a hazard to navigating through the wind farms in fog or at night, it’s hard to see how it would be much of a problem to military vessels or aircraft, which have very sophisticated radars,” he said. He added, however, that “phantom targets” could make it harder to find a vessel that is deemed a threat. 

The pause comes less than a week after a federal judge overturned a January decision by the Trump administration prohibiting the issuance of offshore wind approvals by federal agencies. The ruling, officially entered into the court Thursday, didn’t guarantee the authorization of new projects, but said the agencies have to go through the approval process. It affirmed the rights of states and developers, and potentially created a path for new wind projects to move forward. The judge ruled in favor of a lawsuit by the attorneys general from Massachusetts and several other states that challenged the current administration.

“This is a desperate rerun of the Trump administration’s failed attempt to kill offshore wind — an effort the courts have already rejected,” Sinding Daly said.

Petitions calling for the immediate suspension of all offshore wind projects in the Northeast pending a federal reassessment, also at the end of August, similarly cited concerns of “unprecedented national security risks.” The petitions, filed with eight federal agencies, were led by Green Oceans, which has a local arm based on Martha’s Vineyard, and included the Wampanoag Tribe of Gay Head (Aquinnah). 

The suspension of work on Vineyard Wind 1 also delays the promise of jobs and funds for the Island. Based on a community benefits agreement between the developer of Vineyard Wind 1 and Island nonprofit Vineyard Power, 100 percent of staff at the operations and maintenance facility on Beach Road in Tisbury are to be sourced from Martha’s Vineyard. This is a responsibility of the nonprofit to facilitate, but is required to occur only within five years of the commercial operation date of the project, as stated in an addendum to the agreement, which was estimated to be at the end of this year. Now, that date is up in the air.

Part of the agreement, which generally exchanges on-Island benefits for support of the project, is $7.5 million allocated to the Island over 15 years for energy resiliency and affordability. Though the Island initially received $500,000 from the RAP within 60 days of financial close of the Vineyard Wind project, which occurred on Sept. 15, 2021, more funds to the project won’t come until right after the project reaches commercial operation, which is now unknown.

This renewable energy sector also created an unlikely alliance between the Trump administration and the whales. Representatives of ACK for Whales, a group based in Nantucket that’s been involved in lawsuits against offshore wind projects, said they’re pleased with the announcement.

“Our organization has been primarily focused upon the harm these projects inflict upon our ocean and upon animals like the North Atlantic right whale,” Val Oliver, president of the group, said. “However, there are many other negative impacts from these projects as well. We have long cited the very real threat from radar interference caused by these enormous offshore wind turbines. Not only does this pose a danger to fishermen and others on the water, but this obviously also poses a massive national security threat. It is very satisfying that this threat is finally being recognized and acted upon.”

  1. Electricity in Mass. is more than 30 cents per kWh. Where is the benefit from Vineyard Wind? I will believe my electric bill before I believe the nonsense from Governor Healy.

    “under my plan … electricity rates would necessarily skyrocket.”
    Barack Obama – 2008

    Obama and Biden kept that promise to the American people. I wish they hadn’t.

  2. You know the baby is having a tantrum when they have to come up with a BS excuse like this “classified” one But– let me address a comment from Mr Burgum : “ONE natural gas pipeline supplies as much energy as these 5 projects COMBINED.” — I was skeptical…so I looked up a proposed pipeline in New England that is under permitting review..
    It’s the “project Maple” natural gas pipeline. It is difficult for me to find the exact route of this pipeline, but there is strong local opposition to it in Salem and Weymouth. (Sometimes these things leak and blow up) . This project, which is completely owned by a foreign company, would deliver 750,000 cubic feet of gas per day– an average home in MA. uses the equivalent of about 324 cubic ft. per day Or enough to power 2,314 homes.
    Vineyard wind one alone will produce enough power for 400,000 homes.(72 times more) I don’t mean to put Mr. Burgum on the spot, but I would ask that if we are going to have a rational discussion about an important topic, it would be nice if we could at least get somewhat close to the facts.

    1. Fake stats. Project Maple will produce 750 MILLION cubic feet per day. Split between Ramapo 500 MILLION cubic feet and 250 MILLION at Salem MA.
      The average house consumes about 160 cubic feet although a bit higher in MA due to colder weather. Or about 771,605 additional homes at 324 cubic feet/day.Facts matter.

      1. It seems you are correct about the volume of the project maple pipeline. My apologies. I’m not sure how I got that number– can’t find the source I used, but, you are correct and facts do matter. But the 5 wind projects that are halted will provide power for more than 771,605 homes.
        Thanks for the correction.

  3. This pause should be viewed as prudence, not sabotage.

    For years, offshore wind has been presented to Island communities as an unquestionable good, while legitimate concerns — about fisheries, marine ecosystems, navigation, and now national security — were often brushed aside. The Department of the Interior’s action acknowledges what many here have long argued: projects of this scale deserve reassessment as conditions, technologies, and risks evolve.

    Environmental review does not end once steel is in the water. Fishermen have raised unresolved questions about habitat disruption, altered migration patterns, and access to traditional fishing grounds. Marine scientists continue to debate cumulative impacts on sensitive species, including the North Atlantic right whale. Those concerns do not disappear simply because construction timelines advance.
    Radar interference, now cited as a national security issue, also has practical implications for maritime safety. It affects vessels operating near turbine fields — including fishing boats — and compounds risks in increasingly crowded waters.

    Energy security is not measured only in megawatts. It includes reliability, resilience, ecological stewardship, and protection of critical systems. Projects that rely on heavy subsidies, produce intermittent power, and introduce unresolved environmental and security risks warrant scrutiny — even late in the process.

    A temporary pause to reassess is not anti-renewable. It is responsible governance.

  4. Trump’s attempts to block the Offshore Wind projects have failed in court several times before. They will fail in court once again. The Department of Defense had signed off on these projects years ago and the laws of physics have not changed since that time.

  5. trump has had a career in the casino industry—which includes real estate transactions, sleazy business deals, seedy business elements, and mobster-type relationships, working in a town where prostitution is legal.
    Should we be surprised when he treats the American public the same way? The public exists for his amusement and to make him rich. The tech and oil billionaires have invested in nuclear. They will do everything in their power to destroy solar and wind energy because it will destroy their potential for making billions $ more.

  6. Don’s rebuttal doesn’t actually disprove the claim he’s responding to — it substitutes an unrelated example and mismatched units.

    He compares Vineyard Wind’s electric output to a small, distribution-scale gas pipeline proposal and then measures that pipeline against average residential gas use.

    That is not what Burgum’s statement refers to. Large interstate natural-gas pipelines operate at vastly higher capacities and are designed to supply multiple power plants continuously, not just a few thousand homes.

    More importantly, Don compares finished electric generation from wind to raw fuel volume used for home heating. Those are not equivalent measures. Gas pipelines deliver thermal energy that is converted — with losses — into electricity at power plants or used directly for industrial and heating loads. Using household consumption figures to refute a grid-scale energy claim is the wrong frame.

    That does not mean Burgum’s statement is precise or well-explained. But Don’s arithmetic does not demonstrate that it is false. To evaluate the claim honestly requires comparable infrastructure, comparable scale, and comparable units — not a selectively chosen pipeline and residential averages.

  7. I agree with Duncan’s framing, and one distinction that often gets lost is the difference between offshore siting and wind technology itself.

    I think onshore wind is treated very differently for a reason. Texas alone has roughly 19,000–20,000 operational onshore turbines, many located near or within the orbit of military installations. If land-based wind turbines posed an inherent radar or surveillance risk, Texas would already be the test case — and it isn’t. The Department of Defense routinely addresses onshore projects through siting rules, setbacks, and radar modeling, and turbines are adjusted or approved accordingly.

    That points to two important conclusions. First, wind turbines themselves are not a categorical national-security threat. Second, the concerns being raised now are primarily about offshore placement near coastal waters, naval activity, and other sensitive infrastructure, not about wind generation as a concept.

    Keeping that distinction clear helps prevent the debate from collapsing into absolutes. It allows policymakers and the public to evaluate projects based on location, scale, and context rather than treating all wind development as inherently risky or inherently benign, which ultimately leads to better decisions.

  8. I’m surprised that there is no wind farms outside the White House and the capitol
    Talk about an endless supply of wind and hot air
    One Hakeem Jeffries marathon speech or Trump press conference generates enough wind to charge a thousand electric school buses
