Construction of Vineyard Wind 1 Completed

All wind turbines have been installed at the Vineyard Wind 1 offshore wind farm, according to US media and Oceantic Network, the country’s offshore renewable energy industry organisation.

Located approximately 24 kilometres (15 miles) south of Nantucket, Massachusetts, the 806 MW project features 62 GE Vernova Haliade-X 13 MW wind turbines, each equipped with a 220-metre rotor and 107-metre blades.

Wind turbine installation commenced in September 2023, and Vineyard Wind 1, developed by a joint venture between Avangrid and Copenhagen Infrastructure Partners (CIP), began delivering power to the grid in early 2024.

During construction, Vineyard Wind 1 faced several challenges, including issues related to wind turbine blades and regulatory actions that temporarily halted project activities.

In July 2024, a blade from one of GE Vernova’s Haliade-X turbines broke due to a manufacturing deviation, prompting inspections and a programme to remove and replace blades manufactured at the company’s facility in Gaspé, Canada, after additional units were found to have insufficient bonding. The incident led to regulatory scrutiny and the implementation of mitigation measures, including enhanced inspections and monitoring systems for installed blades.

The project was also one of the five offshore wind farms under construction in the US affected by a stop-work order issued by the US Department of the Interior’s Bureau of Ocean Energy Management (BOEM) in December 2025, which temporarily suspended construction activities.
