Ørsted’s U.S. offshore wind subsidiary Sunrise Wind LLC is taking legal action against the federal government after regulators ordered a suspension of its offshore wind lease late last year, escalating tensions between renewable developers and the current U.S. administration.

Sunrise Wind said it will file a complaint in the U.S. District Court for the District of Columbia challenging a lease suspension order issued on December 22, 2025, by the Department of the Interior’s Bureau of Ocean Energy Management (BOEM). The company also plans to seek a preliminary injunction to block the order while the case proceeds.

The developer argues that the suspension violates applicable law and places the Sunrise Wind project at risk of “substantial harm” if allowed to remain in force. While Sunrise Wind said it continues to seek a negotiated resolution with the administration, it described litigation as necessary to protect the project and its investments.

Sunrise Wind, a wholly owned subsidiary of Danish offshore wind major Ørsted, has already secured all required local, state, and federal permits after what it described as extensive multi-year environmental and regulatory reviews. As part of that process, the project underwent years of consultation with U.S. defense authorities to address potential national security and military aviation concerns.

Those discussions culminated in a formal mitigation agreement between Sunrise Wind, the Department of the Air Force, and defense authorities, clearing the project to proceed from construction through operations. Additional approvals were granted by agencies including the U.S. Coast Guard, U.S. Army Corps of Engineers, and National Marine Fisheries Service.

Construction of the project is now well advanced. Sunrise Wind said the offshore wind farm is nearly 45% complete, with 44 of 84 monopile foundations already installed along with the offshore converter station. Onshore electrical infrastructure is largely finished, and near-shore export cables have been laid.

Before the lease suspension order was issued, Sunrise Wind expected the project to begin generating electricity as early as October 2026. Once fully operational in 2027, the wind farm is contracted to supply power to nearly 600,000 homes under a 25-year agreement with the State of New York.

The company warned that delaying or derailing the project could have broader implications for grid reliability at a time of rising electricity demand. Industry experts, Sunrise Wind said, have flagged increased risks to system reliability if projects like Sunrise Wind fail to come online as planned.

The legal challenge comes amid growing uncertainty for the U.S. offshore wind sector, which has faced cost inflation, supply chain disruptions, and increasing political scrutiny. While New York remains one of the most aggressive offshore wind markets in the country, federal policy signals have become less predictable, particularly around permitting and lease enforcement.

Sunrise Wind also emphasized the project’s economic footprint, noting that it has already supported thousands of U.S. jobs across construction, operations, shipbuilding, and manufacturing. More than 1,000 union workers have logged over one million union work hours on the project to date, according to the company. Ørsted’s broader U.S. investments span grid upgrades, port infrastructure, and a domestic supply chain reaching more than 40 states.

The Sunrise Wind lawsuit follows a similar move earlier this month by Revolution Wind LLC, a separate offshore wind developer jointly owned by Ørsted and Global Infrastructure Partners’ Skyborn Renewables. Revolution Wind filed its own challenge in the same federal court on January 1, 2026, signaling a coordinated legal pushback from offshore wind developers against recent federal actions.
