Revolution Wind LLC has filed a supplemental complaint in the U.S. District Court for the District of Columbia challenging a lease suspension order issued on Dec. 22, 2025 by the Department of the Interior’s Bureau of Ocean Energy Management (BOEM), the company said.
The developer, a 50/50 joint venture between Global Infrastructure Partners’ Skyborn Renewables and Ørsted, said it plans to follow the filing with a motion for a preliminary injunction. Revolution Wind added that it continues to seek a constructive resolution with the administration and other stakeholders regarding the 704-megawatt (MW) offshore wind project.
The company said it believes the lease suspension order violates applicable law and warned that, as with a stop-work order issued in August 2025, a continuation of the action could cause substantial harm to the project.
“Litigation is therefore a necessary step to protect the rights of the project,” Revolution Wind said in a statement.
Revolution Wind said it secured all required federal and state permits in 2023 after regulatory reviews that began more than nine years earlier. As part of the process, the project engaged in years of consultations with the U.S. Department of Defense’s Military Aviation and Installation Assurance Siting Clearinghouse to address potential national security and defence impacts.
Those consultations resulted in a formal mitigation agreement between the Department of War, the Department of the Air Force and Revolution Wind, the company said.
The developer said it has spent and committed billions of dollars in reliance on the permitting process, which also involved approvals from agencies including the U.S. Coast Guard, the U.S. Army Corps of Engineers and the National Marine Fisheries Service.
Construction of the project is at an advanced stage, with Revolution Wind saying it is about 87% complete. All offshore foundations have been installed, along with 58 of 65 turbines. Export cable installation is complete and both offshore substations are in place.
At the time of the lease suspension order, the project was expected to begin generating power as early as January 2026 and is still targeting readiness to deliver electricity in 2026, the company said.
Revolution Wind is designed to supply power to more than 350,000 homes under 20-year power purchase agreements with utilities in Connecticut and Rhode Island. The company said the project would help support growing electricity demand in the U.S. northeast, including from data centres and artificial intelligence, and cited warnings from grid operator ISO New England that halting the project could increase power prices and weaken reliability.
The developer said the project has supported thousands of U.S. jobs across construction, operations, shipbuilding and manufacturing, including more than 1,000 union jobs representing about 2 million union work hours.
Revolution Wind is part of Ørsted’s broader investment in U.S. energy generation, grid upgrades, port infrastructure and a supply chain spanning more than 40 states.
Separately, Sunrise Wind LLC, a wholly owned Ørsted subsidiary that also received a lease suspension order on Dec. 22, said it continues to assess options to resolve the matter, including engagement with relevant agencies and potential legal action.
