Danish renewables giant Orsted, the world’s largest developer of offshore wind farms, said on Friday that it had launched legal action against the Trump administration over the suspension of its $5 billion Revolution Wind project.
Shares of the Copenhagen-listed company rose more than 4% on the news, putting the stock among the top performers of the pan-European Stoxx 600 index.
Orsted said in a statement that it would seek a court injunction against the U.S. government’s decision to halt its Revolution Wind project, located about 15 miles south of the Rhode Island coast.
“As was the case with the August 2025 stop-work order, the Revolution Wind Project … faces substantial harm from a continuation of the lease suspension order. As a result, litigation is a necessary step to protect the rights of the Project,” Orsted said.
“Revolution Wind has spent and committed billions of dollars in reliance upon, and has met the requests of, a thorough review process,” the company added.
The pro-fossil fuel Trump administration suspended leases on Dec. 22 for five large offshore wind projects, including Revolution Wind, citing national security concerns identified by the Pentagon.
The move marked the latest in a string of blows against offshore wind developers, with U.S. President Donald Trump having previously described wind turbines as “ugly” and an economic and environmental “disaster.”
Revolution Wind is a 50/50 joint venture between Orsted and Global Infrastructure Partners’ Skyborn Renewables. In a filing last year, Orsted and Skyborn Renewables said they had already spent approximately $5 billion on the project.
