Construction can continue on a multibillion-dollar offshore wind project designed to supply 350,000 homes with electricity across Connecticut and Rhode Island.

On Monday, a federal judge allowed work to resume on Revolution Wind exactly one month after the Trump administration abruptly issued a stop work order – even though the project was 80% finished.

Calling the delay “arbitrary and capricious,” U.S. District Judge Royce Lamberth blasted the U.S. Department of Interior for offering contradictory reasons for its order.

“There is no question in my mind of irreparable harm to the plaintiff,” said Lamberth, a Reagan appointee. “If Revolution Wind cannot meet benchmark deadlines, the entire project could collapse.”

Ørsted, the renewable energy project’s Danish developer, argued that it is $2.3 million per day. The company said in a statement that it will “resume impacted construction work as soon as possible, with safety as the top priority.”

“I haven’t had a chance to follow-up with Ørsted yet to see what the timing is, but it’s good news on behalf of the consumers and bringing down the price of electricity,” said Gov. Ned Lamont. “We had extensive conversations, negotiations over the weekend, but more importantly, the courts just lifted the stop-work injunction.”

Connecticut has also invested more than $300 million in State Pier upgrades to build wind turbines – three times more than the original cost estimate.

The Interior Department issued a stop work order on Aug. 22, citing unspecified national security concerns. The department later said it needed more time to review interference with military radar, fisheries studies and possible undersea drone attacks.

“There’s evidence that not a full review was completed under the Biden administration,” Interior Secretary Doug Burgum told CNN days after the pause. “There’s concerns about radar relative to undersea and that doesn't have to be a large Russian sub, but undersea drones.”

But the Bureau of Ocean Energy Management’s own review concluded the “impacts would be negligible and avoidable.” Planners already coordinated with the U.S. Navy to mitigate radar and electromagnetic emissions effects.

“It’s just kind of at [Trump’s] whim because he feels like it. There’s no thoughtful basis behind what they’re doing here, except they hate wind, and they want to make money for their fossil fuel cronies,” said Connecticut Attorney General William Tong. “BOEM … is contradicting itself from not just two years ago, when they fully vetted and approved this project, but they’re contradicting positions they're taking in other litigation.”

President Donald Trump is a vocal critic of wind power. He signed an executive order shortly after taking office ordering a review of all existing permits.

"We will drill, baby, drill,” Trump said during his inauguration speech.

The administration could appeal but indicated it would let Monday’s injunction stand while lawsuits filed by Connecticut, Rhode Island and Ørsted play out.

“As a result of the Court’s decision today, Revolution Wind will be able to resume construction as BOEM continues its investigation into possible impacts by the project to national security and prevention of other uses on the Outer Continental Shelf,” said Interior spokesperson Elizabeth Peace in a statement. “The Department of the Interior remains committed to ensuring that prior decisions are legally and factually sound.”

Lamont plans to hold a news conference about Revolution Wind with Rhode Island Gov. Dan McKee on Tuesday morning.

“If you want to talk about the birds and the fish and national security, we can do that,” Lamont said. “But in the meantime, let’s get back to work."
