The Trump administration has halted construction on a nearly complete offshore wind project near Rhode Island.

Danish wind farm developer Orsted says the Revolution Wind project is about 80 percent complete, with 45 out of its 65 turbines already installed.

Despite that progress — and the fact that the project had cleared years of federal and state reviews — the Bureau of Ocean Energy Management issued the order last week, saying the federal government needs to review the project and “address concerns related to the protection of national security interests of the United States.”

It did not specify what the national security concerns are.

Rhode Island Gov. Dan McKee criticized the stop-work order and said he and Connecticut Gov. Ned Lamont “will pursue every avenue to reverse the decision to halt work on Revolution Wind” in a post on X.

Construction on Revolution Wind began in 2023, and the project was expected to be fully operational next year. Orsted says it is evaluating the financial impact of stopping construction and is considering legal action.

Revolution Wind was expected to be Rhode Island and Connecticut’s first commercial-scale offshore wind farm, capable of powering more than 350,000 homes.
