On December 22, citing security concerns, the U.S. Department of the Interior (DOI) announced that it was pausing leases for all offshore wind projects currently under construction. The stop-work order blocks further construction of Vineyard Wind 1, Revolution Wind, Coastal Virginia Offshore Wind, Sunrise Wind, and Empire Wind 1. All five projects had obtained leases during the Biden administration. Vineyard Wind 1 is already partially operational, with nearly half of the project’s 62 turbines generating electricity. Both Empire Wind and Revolution Wind were the subject of prior stop-work orders, but following negotiations with the Trump administration in the case of Empire Wind and litigation in the case of Revolution Wind, both projects had resumed construction. Currently, only two small wind farms in U.S. coastal waters are fully operational – Block Island Wind off the coast of Rhode Island with five turbines and South Fork Wind off the coast of New York with twelve turbines.
In announcing the work stoppage, Secretary of the Interior Doug Burgum claimed that “recently completed classified reports” by the Department of Defense (DOD) identified possible radar interference as a potential security risk. Project proponents have noted that the project permitting process included review and approval by the DOD.
This latest stop work order will likely be challenged. Earlier this month, a federal court in Massachusetts ruled that the administration’s ban on the review of offshore wind permits, a policy announced when President Trump took office, was illegal. There, the court determined that in the absence of a clearly articulated rationale beyond the President’s personal contempt for wind turbines, the offshore ban was arbitrary and capricious and a violation of the Administrative Procedures Act (APA). While the DOI’s new stop work order cites emerging national security concerns, a federal court may ultimately need to determine whether it, too, violates the APA. In the meantime, approximately $25 billion worth of projects and an estimated 10,000 jobs face an uncertain future.
