DOER and the Distribution Companies have made a joint Informational Filing at the DPU to notify the Department that they are extending the Bid Submission Date and subsequent solicitation schedule dates for the 83E Round 2 solicitation. Bids are now due on October 8, 2026 at 12:00pm EDT. This extension is intended to allow for additional time for bidders to develop their bids. The Evaluation Team has reviewed the bidder questions, and considered the quantity and content, as well as continued requests past the deadlines in making this determination. The Evaluation Team will continue to respond to questions received prior to the August 20, 2026 deadline and plans to publish the responses by September 10, 2026. DOER and the Distribution Companies believe that revising the solicitation schedule for the Section 83E Round II RFP to account for this ongoing process is crucial to encouraging the development of the strongest, most cost-effective bids for the benefit of Massachusetts ratepayers.
