Danish renewable energy company Ørsted is piling the pressure on the Trump administration’s decision to suspend leases for offshore wind projects off the US east coast over “national security concerns” with another lawsuit.

Revolution Wind, a 50/50 joint venture between Skyborn Renewables and Ørsted, has already legally challenged the lease suspension order since the developers believe the lease suspension order “violates applicable law [as] was the case with the August 2025 stop-work order”, which was cancelled by a judge at the DC District Court.

Because the Revolution Wind project “faces substantial harm from a continuation of the lease suspension order” the developer saw litigation as a necessary step to protect the project. 

Ørsted previously said that it was evaluating all options to resolve the same matter for its Sunrise Wind project.

The company has now decided to file a complaint in the US District Court for the District of Columbia to challenge the lease suspension order for Sunrise Wind. This will be followed by a motion for a preliminary injunction.

As is the case with Revolution Wind, Ørsted believes that the lease suspension order violates applicable law and sees litigation as the only way to protect its rights.

The Danish firm said that it engaged in years-long consultation with the US Department of War to address potential impacts to national security and defence capabilities. That resulted in an agreement between the Department of War, the Department of the Air Force, and Sunrise Wind outlining mitigation measures by the project.  

According to Ørsted, the project is nearly 45% complete. It has installed 44 of 84 monopile foundations as well as the offshore converter station. Construction of the onshore electric infrastructure is substantially complete, and near-shore export cables have been installed. At the time of the lease suspension order, the project was expected to begin generating power as soon as October 2026.

Sunrise Wind is designed to deliver power to nearly 600,000 homes once fully operational in 2027 under a 25-year contract with the State of New York.
