All five developers with offshore wind farms under construction in the US are contesting the suspension order issued by the US Department of the Interior (DOI) in December 2025. Vineyard Wind, owned equally by Avangrid and Copenhagen Infrastructure Partners, announced on January 15 that it had filed for a temporary restraining order and preliminary injunction.
Vineyard Wind seeks to resume work on the 806 MW Vineyard Wind 1 offshore wind farm through a complaint filed in the US District Court for the District of Massachusetts. The company argues that the stop-work order could cause irreparable harm to the project.
“Vineyard Wind continues to work with the Bureau of Ocean Energy Management, the Bureau of Safety and Environmental Enforcement, and other relevant stakeholders and authorities in the Administration to understand the matters raised in the Order. 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 to the communities who will benefit from this critical source of new power for the New England region,” the developer remarked on January 15.
Vineyard Wind 1 began producing electricity from its first wind turbines in February 2024 and became the largest operating wind farm in the US by June 2024, with over 136 MW connected to the Massachusetts grid.
According to the stop-work order issued to Vineyard Wind on December 22, 2025, the DOI’s Bureau of Ocean Energy Management (BOEM) permits activities related to the wind farm’s already operating turbines to continue.
“[Given] that this project is partially generating power, you may continue any activities from those wind turbines that are necessary for the current level of power generation,” the suspension order for Vineyard Wind 1 states.
The legal action follows other complaints by offshore wind developers in US federal court seeking preliminary injunctions. Ørsted and Skyborn Renewables’ 704 MW Revolution Wind and Equinor’s 810 MW Empire Wind 1 have been cleared to resume construction. Meanwhile, Ørsted has filed for an injunction for its 924 MW Sunrise Wind project, and Dominion Energy is seeking to restart its 2.6 GW Coastal Virginia Offshore Wind (CVOW) project, with a hearing scheduled for January 16, according to US media.
