Request for Proposals for Long-Term Contracts for Offshore Wind Energy Projects issued by Massachusetts Electric Distribution Companies in coordination with the Massachusetts Department of Energy Resources. This is Massachusetts' third offshore wind solicitation under Section 83C of Chapter 169 of the Acts of 2008, as amended by Chapter 188 of the Acts of 2016 and Section 21 of Chapter 227 of the Acts of 2018. The solicitation seeks reasonable proposals to enter into cost-effective long-term contracts for offshore wind energy generation and associated RECs, which may include associated transmission costs. The Distribution Companies are seeking to procure at least 400 MW and up to 1600 MW of offshore wind energy generation. Bidders may offer proposals from 200 MW up to approximately 1600 MW with no preferred bid size. The solicitation target is part of a procurement schedule to ensure the Distribution Companies enter into cost-effective contracts for Offshore Wind Energy Generation equal to an additional approximately 1600 MW of aggregate nameplate capacity not later than December 31, 2035. Key evaluation criteria include price competitiveness against a price cap, deliverability analysis, economic benefits to the Commonwealth (employment benefits, diversity, workforce development, supply chain, port investments, research and innovation), environmental and socioeconomic impacts from siting, ability to produce Clean Peak Energy Certificates (CPECs), and other qualitative factors. Phased projects must maintain the same nominal levelized price per MWh across all phases. All bids must include a commitment to enter into a Voluntary Agreement. The solicitation includes requirements for site control documentation and technical analysis to identify potential deliverability constraints.
