83E Timeline

The Massachusetts Electric Distribution Companies (EDCs), acting through Maclean Energy, have issued the Section 83E II Request for Proposals (RFP) to procure long-term offshore wind energy generation for the Commonwealth. Issued on July 31, 2025, this solicitation is the second competitive procurement round conducted under Section 83E of the Massachusetts General Laws, which authorizes the EDCs to enter into long-term contracts for offshore wind energy. The selected projects will deliver renewable energy to Massachusetts ratepayers and contribute to the state's clean energy goals. This RFP follows the earlier Section 83C procurement framework and is part of Massachusetts' broader 83C/83E solicitation series, which also includes the 83C III, 83C IV, and 83E II solicitations documented on the Maclean Energy website.

Bidders must submit both confidential and public versions of their proposals. A bidders conference was conducted on August 14, 2025, and the deadline for submission of questions was August 21, 2025. The due date for submission of confidential and public proposals is September 10, 2025 at 12:00 (noon) ET. All schedule changes are posted on the Distribution Companies' website at macleanenergy.com, and the Evaluation Team reserves the right to revise the schedule as necessary, including the right to establish a schedule different from that set forth in the RFP.

The procurement schedule, as revised, calls for selection of projects and commencement of negotiations on December 19, 2025. Execution of long-term contracts and the Memorandum of Understanding with the Massachusetts Department of Energy Resources (DOER) is anticipated by May 15, 2026, and submission of the executed long-term contracts to the Department of Public Utilities (DPU) for approval is scheduled at a date to be determined. On March 27, 2026, the EDCs filed a notice with the DPU regarding a change in the anticipated contract execution date, and the revised schedule reflects this extension.

Bidders and interested parties should monitor the Maclean Energy website for responses to bidders' questions (issued in batches), bidder conference materials, notices of intent to bid, and any further schedule revisions. The RFP website hosts dedicated pages for the timeline, documents, bidder conference, Q&A, and submitted bids. Proposals will be evaluated by the Evaluation Team representing the EDCs, and selected projects will move into contract negotiation, with long-term contracts requiring DOER memorandum and DPU approval.
