Vineyard Wind, a joint venture between Iberdrola’s US arm Avangrid and Copenhagen Infrastructure Partners, has sued the Trump administration to fight the suspension order issued last month.

The company filed for a temporary restraining order and a preliminary injunction in the US District Court for the District of Massachusetts, challenging the suspension order issued by the US Department of the Interior’s Bureau of Ocean Energy Management (BOEM) on December 22, 2025. 

“Vineyard Wind continues to work with BOEM, BSEE, and other relevant stakeholders and authorities in the administration to understand the matters raised in the order,” the company explained.

However, Vineyard Wind believes the order violates applicable law and, if not promptly enjoined, will lead to immediate and irreparable harm to the project and the communities that will benefit from this source of new power for the New England region.

The 62-turbine project has been under construction since 2021, and at the time of the stop-work order, was 95% complete and already generating power for the New England grid. The company said it has spent $4.5bn on the project and is losing about $2m per day during the shutdown.

If the halt remains in place, Vineyard Wind also stated that it will be unable to complete construction before it loses access to an installation vessel that is under contract with the company until March 31, 2026.

“The inability to timely complete construction of the project in turn jeopardises the revenues and financing necessary for the project to remain viable,” the company said in its complaint to the court.

The Interior halted five offshore wind projects under construction – Vineyard Wind 1, Revolution Wind, Coastal Virginia Offshore Wind, Sunrise Wind, and Empire Wind 1.

The projects are worth over $10bn in combined investment and have enough capacity to power over two million homes. So far, Revolution Wind and Empire Wind have been given permits to restart construction after winning their cases in court.
