The solicitation invites qualified developers to submit confidential and public proposals for offshore wind generation projects that will deliver clean energy to Massachusetts ratepayers. The RFP schedule included a Bidders Conference on October 5, 2023 and a deadline for submission of questions of October 17, 2023.

The original proposal submission deadline of January 31, 2024 was extended to March 27, 2024 at 12:00 noon EDT. Following proposal evaluation, the Evaluation Team selected projects and commenced negotiations on September 6, 2024.
