June 30, 2026, is the revised target deadline for Massachusetts and developers to finalize power offtake contracts for the state’s fourth major offshore wind procurement. These ongoing contract negotiations—which involve major projects like SouthCoast Wind—have faced repeated delays.
.
The Massachusetts Department of Energy Resources (DOER) and project developers are targeting June 30, 2026, for contract execution, with formal filing with the Department of Public Utilities (DPU) expected to follow by late August.
.
In June 2023, SouthCoast Wind (then known as Mayflower Wind) filed to terminate all nine of its existing power purchase agreements (PPAs) with Massachusetts utilities. SouthCoast walked away from its 2019 (800 MW) and 2021 (400 MW) contract wins.
.
After winning the 2024 bid, final execution of the power contracts with utilities has faced a series of rolling delays:
.
Delay #1 (March 2025)
Delay #2 (June 2025)
Delay #3 (December 2025)
Delay #4 (Current Status): Unknown
.
In late 2025, the Bureau of Ocean Energy Management (BOEM) requested a revocation and remand of SouthCoast Wind's Construction and Operations Plan (COP).

Massachusetts residents face some of the highest electricity prices in the country.
