April 13, 2026 — Vineyard Wind has completed construction of the 62-turbine wind farm southwest of Nantucket, but the future of the project appears to be very much in jeopardy.
Vineyard Wind is suing GE Renewables, the manufacturer of its turbines, to block the company from backing out of the project. Without its partner, Vineyard Wind stated in its lawsuit that the entire $4.5 billion offshore wind project is imperiled.
“GER (GE Renewables) walking away threatens the project’s very survival,” Vineyard Wind’s attorneys wrote in a filing submitted this week to the Suffolk Superior Court. The project’s failure would “leave behind a dormant wind farm graveyard. There is no viable replacement.”
The lawsuit was prompted by GE Renewables (GER) sending a termination notice to Vineyard Wind on February 27, claiming the offshore wind developer had failed to cover more than $300 million in unpaid bills. Terminating those agreements would leave Vineyard Wind unable to operate and maintain its turbines, which run on GE Renewables’ proprietary designs, technology, and software, according to the legal filing.
“Only GER is able to perform the remaining work necessary to bring the performance of the GER turbines up to the capacity and reliability standards required for Vineyard Wind to supply power to Massachusetts consumers,” the offshore wind developer stated in the lawsuit. “Even if it were doable, however, it will be virtually impossible to find a turbine supplier that would be willing to take GER’s place.”
