Vineyard Wind 1 Completes Construction, All 62 Offshore Wind Turbines Providing Affordable Power to Massachusetts

BOSTON - The completion of Vineyard Wind 1 marks the largest offshore wind project to be completed in the United States, providing up to 800 megawatts of power to Massachusetts that reduces carbon emissions, protects wildlife, and addresses the rising demand for energy. The 62-turbine project will generate enough electricity to power more than 400,000 homes across the Commonwealth.

"The completion of Vineyard Wind 1 is a long time coming. Massachusetts has had sights set on offshore wind energy for decades, and now we can celebrate that clean, reliable power reaching homes and business across the Commonwealth," said Amber Hewett, senior director of offshore wind energy at the National Wildlife Federation. "We were reminded how much strain the New England power grid endures during this cold, expensive winter - exactly when the wind offshore blows strongest - and why we need affordable, reliable energy that also protects wildlife and communities from harmful emissions. Following years of public input, environmental impact studies, military consultation, construction and operation planning, permitting, and installation, Massachusetts ratepayers will finally reap the full benefits of this commercial-scale offshore wind project."

The completion of Vineyard Wind 1 was delayed on December 22, 2025 when the Trump Administration issued a stop-work order on all offshore wind projects currently under construction citing unspecified national security concerns from the Department of Defense. The developers of all five projects, including Vineyard Wind 1, which was 95% complete at the time, filed lawsuits challenging these alleged concerns, pointing towards their years-long engagement with the Pentagon throughout the development process - some dating back to the first Trump Administration.

Vineyard Wind 1 sued on January 15, with a hearing held on January 23 in the District Court of Massachusetts. Judge Brian E. Murphy issued a stay from the bench, allowing the project to resume construction.
