Vineyard Wind, a 50:50 joint venture between Avangrid and Copenhagen Infrastructure Partners (CIP), and GE Vernova have reached an agreement to resolve all outstanding litigation related to the Vineyard Wind offshore wind project in Massachusetts.
Under the settlement, GE Vernova has withdrawn its notice of termination and both parties have agreed to dismiss all pending legal claims. The companies said the settlement terms, which end the commercial litigation between the project developer and turbine supplier, are confidential.
The dispute followed GE Vernova’s February 2026 notice of termination of its contracts with Vineyard Wind. The turbine supplier had cited withheld payments as the reason for termination, but Vineyard Wind argued that it was entitled to withhold around USD 308 million based on contractual claims related to delays and issues with blades on GE Vernova's turbines at the offshore wind farm.
A Massachusetts Superior Court granted Vineyard Wind a preliminary injunction in April preventing GE Vernova from terminating its role on the project and requiring it to continue performing under the turbine supply and service agreements while the dispute continued. The court later denied GE Vernova’s appeal of the injunction.
The 806 MW Vineyard Wind 1 offshore wind farm is located approximately 24 kilometres south of Nantucket, Massachusetts. The project comprises 62 GE Vernova Haliade-X 13 MW turbines, all of which were in place in March 2026.
In their statement, issued on 16 September, Vineyard Wind and GE Vernova said the project is now capable of producing power from all turbines and is supplying electricity to more than 400,000 homes and businesses in Massachusetts and New England.
The companies also said Vineyard Wind 1 has created nearly 4,000 jobs and generated USD 1.94 billion in economic output to date. According to the statement, the project is expected to reduce carbon emissions by more than 1.6 million tonnes annually.
