The deadline for companies to finish up contracts covering part of the state’s slow-to-start wind power plans has blown by once more without any deals in place and will again be pushed, this time to the end of the year.

The June 30 deadline to execute wind energy contracts comes following a 2023 request for proposal from the Healey Administration for the state’s “fourth and largest offshore wind solicitation.”

According to a spokesperson for DOER, the companies who bid on the project are facing federal headwinds.

“While the utilities and developers continue their hard work to memorialize the bids in binding contracts, the uncertainty created by the changing federal landscape makes it difficult to finalize contracts,” Lauren Diggin said on behalf of DOER.

This is at least the fourth time the companies behind the proposed project — Unitil, National Grid, and Eversource Energy — have indicated they will need more time to complete contract negotiations. The original deadline was on Aug. 14, 2024. When that passed, the deadline was moved to the following November, and then January. On March 31 it was pushed to June.

The companies’ most recent letter, dated June 30, says that things have grown a complicated since March.

“Due to ongoing uncertainty caused by federal level activities, the counterparties have not yet completed their contract negotiation,” they wrote, setting new dates of December 31 to finish negotiations and February 25 to file with the DPU.

Despite the delay, Diggin said the Bay State remains committed to the idea of wind power.

“Massachusetts is committed to an all-of-the-above approach to energy, including offshore wind. Offshore wind produced locally in Massachusetts will help lower costs, create thousands of jobs, and move us toward energy independence,” she told the Herald.
