Vineyard Wind 1, the 800 MW offshore wind farm off Massachusetts, reached full commercial operation on 29 October 2026, following years of construction delays, regulatory challenges and a turbine blade failure.
The milestone was confirmed by project spokesperson Craig Gilvarg in a statement to WBUR. The $4.5 billion development comprises 62 wind turbines located approximately 15 miles off the Massachusetts coast, with enough generating capacity to supply around 400,000 homes.
The announcement follows the full commissioning of the 704 MW Revolution Wind project, which supplies electricity to Rhode Island and Connecticut. Both offshore wind farms are now commercially operational, adding substantial generating capacity to New England’s electricity grid.
Vineyard Wind 1 was selected by Massachusetts in 2018, but its development encountered several major setbacks. Federal permitting delays began in 2019 before construction received approval under the Biden administration in 2021.
The project suffered another setback in 2024 when a turbine blade failed, releasing debris into the ocean and onto beaches around Nantucket. The incident prompted a federal investigation and delayed construction activities.
In December 2025, the Trump administration suspended work on Vineyard Wind 1 and four other offshore wind projects, citing national security concerns. The project was subsequently allowed to resume full activities following a federal court decision on 27 January 2026.
Offshore construction was completed in March 2026, with the remaining turbines undergoing commissioning before full commercial operation began in October. Approximately 3,500 people were employed during the project’s development and construction.
The completion comes as the wider US offshore wind industry continues to face political and regulatory uncertainty. Federal restrictions have affected other developments, while proposed permitting reforms remain under consideration in Congress.
With Vineyard Wind 1 and Revolution Wind now operating commercially, New England has two additional large-scale offshore wind projects contributing to its regional electricity supply.
