All wind turbines are now installed at the Vineyard Wind 1 offshore wind farm, according to US media and the Oceantic Network, the offshore renewable energy industry organization.
Situated about 24 kilometers (15 miles) south of Nantucket, Massachusetts, the 806 MW project includes 62 GE Vernova Haliade-X 13 MW wind turbines, each featuring a 220-meter rotor and 107-meter blades.
Wind turbine installation began in September 2023, and Vineyard Wind 1, developed by Avangrid and Copenhagen Infrastructure Partners (CIP), started supplying power to the grid in early 2024.
The project encountered challenges during construction, such as issues with wind turbine blades and regulatory actions that temporarily halted activities.
In July 2024, a blade from a GE Vernova Haliade-X turbine failed due to a manufacturing defect, leading to inspections and a replacement program for blades from Gaspé, Canada. The incident triggered regulatory scrutiny and the adoption of enhanced inspection and monitoring systems for installed blades.
Vineyard Wind 1 was among five U.S. offshore wind farms affected by a stop-work order from the U.S. Department of the Interior’s Bureau of Ocean Energy Management in December 2025, suspending construction activities.
At the time of the order, the Vineyard Wind venture stated the project was 95% complete, with one turbine to be installed, blades on ten turbines to be replaced, and the remaining 18 turbines to be activated.
In a legal action following the construction pause, which sought a preliminary injunction, Vineyard Wind argued the stop-work order risked the completion plan, as a vital vessel, DEME’s jack-up vessel Sea Installer, was chartered under the project’s timeline with a March 31 completion date.
The announcement of the final turbine installation coincided with news that Revolution Wind, owned by Ørsted and Skyborn Renewables, began supplying power to the New England grid.
“U.S. offshore wind advances with the third U.S. project now providing much-needed electricity to the grid, lowering winter energy bills for millions of Americans,” Oceantic Network stated regarding updates on the projects.
“The growing 40-state supply chain supported installations across five projects simultaneously, creating over 12,000 jobs and driving $25 billion in American investments into shipyards, ports, and manufacturing centers. These milestones highlight offshore wind as a proven energy resource delivering reliability, affordability, and economic benefits.”
