Massachusetts Initiates Vineyard Wind Agreements, Securing 20-Year Rates

The State of Massachusetts secures 20-year fixed pricing for Vineyard Wind 1, projecting USD 1.4 billion savings.

Massachusetts has implemented long-term contracts for the Vineyard Wind 1 offshore wind farm, securing fixed electricity pricing for 20 years with expected customer savings of USD 1.4 billion (approximately EUR 1.2 billion) over that period, according to the state government.

Announced on April 27 by the Healey-Driscoll administration, these contracts are projected to deliver average savings of 1.4 USD cents per kWh on electricity bills. This comes after the project’s participation in wholesale electricity markets, further reducing costs.

The 806 MW Vineyard Wind, situated about 24 kilometers (15 miles) south of Nantucket, completed construction in March. The wind farm has been producing electricity since January 2024, following its late 2022 construction start and installation of the first GE Haliade-X wind turbines in 2023.

The state government reports that the offshore wind farm contributed to lower electricity prices during winter by providing power at reduced rates compared to other sources and supporting grid reliability during high demand periods.

Vineyard Wind 1 is anticipated to cut carbon emissions by over 1.6 million tonnes annually, creating nearly 4,000 jobs and generating USD 1.94 billion (approximately EUR 1.66 billion) in economic output, according to the administration.

This project, a 50-50 joint venture between Avangrid and Copenhagen Infrastructure Partners (CIP), faced several setbacks during construction and commissioning.

In 2024, a turbine blade defect led to halted operations, inspections, and the replacement of multiple blades, temporarily suspending power generation. Additionally, in December 2025, the US government issued a stop-work order affecting five offshore wind farms, including Vineyard Wind 1, which was nearing completion.

Recently, Vineyard Wind entered a legal dispute with turbine supplier GE Vernova. The developer filed a lawsuit to prevent the termination of its turbine supply and service contract amid disputes over payments and liability related to the blade issues. A US court has issued a preliminary injunction requiring GE Vernova to continue work on the project while the conflict is resolved.
