A Massachusetts judge has temporarily barred GE Vernova from leaving its service contract with Vineyard Wind, finding that the developer would face irreparable harm if the turbine supplier withdrew.

The dispute centers on competing financial claims. GE Vernova says Vineyard Wind owes more than $300 million. Vineyard Wind, in turn, says it is owed more than $800 million and links those costs to a blade failure in July 2024. That incident led to the removal and replacement of more than 60 blades across the 62-turbine project.

In the ruling, Judge Krupp rejected the view that Vineyard Wind could simply bring in replacement contractors to complete installation work and address issues involving a proprietary turbine design. The judge said it was “fanciful” to suggest that other contractors could do that work without GE Vernova’s specialized knowledge.

The decision puts focus on a key issue in offshore wind operations and maintenance: the relationship between a developer and a turbine manufacturer can remain critical after handover. It also highlights the importance of the contractual structure that governs ongoing service, troubleshooting, and asset management.

The next hearing is set for 1 May.
