The Trump administration’s legal setbacks are good news for offshore wind and the grid

The Trump administration suffered a series of legal setbacks this week after judges allowed work to resume at several offshore wind farms under construction on the East Coast.

The Interior Ministry ordered the halt of five projects totaling 6 gigawatts of generating capacity in December, due to national security concerns. The injunctions will allow three projects to resume construction: Revolution Wind off Rhode Island, Empire Wind off New York, and Coastal Virginia Offshore Wind off — you guessed it — Virginia.

Both developers filed lawsuits shortly after the Trump administration issued the stop-work order, which was in effect for 90 days.

When the government announced the shutdown a few days before Christmas, the government cited concerns that wind farms might interfere with radar operations. It’s a legitimate concern, and one that the government and project developers have wrestled with throughout the siting and permitting process. Wind farms can be sited to minimize disruption to existing radar facilities, and the radar equipment itself can be upgraded to filter out noise generated by the rotation of turbine blades.

President Trump himself has made no secret that he is not a fan of offshore wind: “I’m not a fan of windmills,” he told oil company executives last week.

In early hearings, the justices were unimpressed with the government’s reasoning. In three separate courtrooms in Virginia and Washington, D.C., the Trump administration’s arguments were met with skepticism.

U.S. District Judge Carl Nichols, a Trump appointee, noted that the government failed to address many of plaintiff Equinor’s arguments in the lawsuit. Equinor, which is developing Empire Wind, claimed the Home Office order was “arbitrary and capricious”. “Your summary doesn’t even include an arbitrary word,” Nichols said, according to the Associated Press.

Nichols also questioned why the Trump administration was required to halt construction when its main national security concern appeared to be with operating the wind farm.

U.S. District Judge Jamar Walker, who heard the lawsuit brought by Dominion Energy, the developer of Coastal Virginia’s offshore wind power company, questioned the government along similar lines. He also said the Interior Department’s order was too broad when viewed in the context of the Virginia project.

Two projects remain in limbo as their lawsuits make their way through the courts. Ørsted, which is developing Sunrise Wind, is scheduled for a hearing on February 2, while the developers of Vineyard Wind 1 only filed their lawsuit on Thursday.

The East Coast could produce up to 110 gigawatts of offshore wind by 2050, according to a Department of Energy study published in 2024. That would provide a major boost to some of the most densely populated cities — and data center regions — in the country. The Northeast currently sees some of the highest electricity costs in the country, while the Mid-Atlantic grid operator has recently come under fire for high electricity prices in its territory. Offshore wind, as one of the cheapest forms of new generation energy, has the potential to slow or reverse this trend.

The potential becomes even greater when we look at it at the national level. Offshore wind could generate 13,500 terawatt-hours of electricity annually, which is three times what the United States currently consumes.
