Vineyard Wind

Vineyard Wind 1 is an offshore wind energy project located about 24 km (15 mi) south off the coast of Martha's Vineyard, Massachusetts, United States. Vineyard Wind 1 features 62 fixed-bottom wind turbines, with a combined nameplate capacity of 804MW. At peak production, this provides energy equivalent of powering 400,000 homes. The turbines used are manufactured by GE Offshore Wind, each capable of generating up to 13MW. The $4 billion project was developed by Copenhagen Infrastructure Partners in partnership with Iberdrola and aims to contribute substantially to Massachusetts' renewable energy targets while reducing carbon emissions. The Massachusetts Department of Public Utilities approved the project in 2019, and construction began in November 2021. Power from the first turbine started flowing into the ISO New England grid in January 2024. The onshore cable landing sites is an onshore substation in Hyannis village, positioned next to the existing Eversource substation.

Construction of the wind farm was completed when the final wind turbine was installed on March 13, 2026. The wind farm was originally expected to be completed by the end of 2025. However construction was paused in late December 2025 due to a Trump administration order to pause all offshore wind leases to review "national security risks". A preliminary court injunction in January 2026 allowed construction to resume while the lawsuit proceeds.
