Vineyard Wind and GE Vernova have reached a settlement ending their legal dispute over a $4.5 billion offshore wind project located south of Martha’s Vineyard. The companies announced Wednesday that they have resolved all outstanding litigation amicably and agreed to dismiss all pending claims related to the disagreement.

The conflict began earlier this year after GE Vernova sought to terminate its contracts with Vineyard Wind for turbine construction and maintenance, citing more than $300 million in unpaid bills. In response, Vineyard Wind sued to prevent GE Vernova from withdrawing from the project, arguing that the company’s specialized technology and expertise were critical to the wind farm’s operation and that losing its turbine supplier would cause “irreparable harm.”

The dispute, which was filed in Suffolk Superior Court, also involved claims regarding a turbine blade failure in July 2024. The incident resulted in debris scattering into the ocean and washing ashore on Nantucket beaches. Vineyard Wind alleged that GE Vernova owed over $850 million in damages due to the blade defect and related costs, which it said offset GE Vernova’s claims for unpaid bills. A court judge barred GE Vernova’s subsidiary from leaving the project and denied the company’s request to move the case to arbitration.

Details of the settlement remain confidential, with neither party disclosing whether any financial terms were agreed upon or clarifying GE Vernova’s ongoing role in the maintenance of the wind farm.

The 62-turbine, 800-megawatt project began generating power in 2024. Prior to a halt ordered by the Trump administration in December, Vineyard Wind had sold enough electricity to power about 50,000 homes. According to the companies, all turbines at the farm are now operational and capable of producing energy sufficient for more than 400,000 homes and businesses. They also reported that the project has created nearly 4,000 jobs and generated $1.94 billion in economic output.
