AI overview

This Request for Proposals (RFP) seeks long-term contracts for offshore wind energy projects under Section 83C of the Green Communities Act in Massachusetts. It represents the second solicitation round (83C II) and is issued jointly by the state's electric distribution companies (National Grid, Eversource, and Unitil) in coordination with the Massachusetts Department of Energy Resources. The goal is to procure utility-scale offshore wind energy to advance the Commonwealth's renewable energy targets, reduce greenhouse gas emissions, and foster economic development.

The RFP package includes the main solicitation document (originally published May 23, 2019 and revised August 7, 2019), bidder response forms, a Cost and Price Proposal Detail (CPPD) form, bid fee submittal form, and an economic development summary sheet. Two draft Power Purchase Agreements are provided: one for National Grid and a separate version for Eversource and Unitil. Bidder conferences and response deadlines were established during the solicitation period, though specific dates are not listed on this resource page.

Key requirements include demonstrating technical and financial capability to develop, construct, and operate an offshore wind project of significant scale. Bidders must also submit detailed plans for in-state economic benefits, including job creation, supply chain investment, and community engagement. The evaluation process considers price, project viability, economic development impact, and environmental benefits. The RFP is supported by a DPU order and updated utility standards of conduct to ensure a fair and transparent procurement process.
