What Mayflower Wind does
Mayflower Wind, operating under the trade name SouthCoast Wind, is a US-based offshore wind energy development company headquartered in Boston, Massachusetts. The company holds a federal offshore lease area located over 30 miles south of Martha's Vineyard and 20 miles south of Nantucket, with technical potential to generate more than 2,400 megawatts of clean energy. Its primary development, SouthCoast Wind Project 1, has been awarded power purchase agreements by the Commonwealth of Massachusetts and the State of Rhode Island to deliver 1,287 megawatts of clean electricity under long-term contracts, and in October 2024 received unanimous major permit approvals from the Massachusetts Energy Facilities Siting Board. Commercial operation is targeted for the end of the 2020s.
The company is legally organized as SouthCoast Wind Energy LLC, a private limited liability company wholly sponsored by OW Ocean Winds, an established global offshore wind developer that provides financial backing, development expertise, and operational resources. Its core technology stack comprises conventional offshore wind generation assets, including utility-scale turbines, subsea transmission infrastructure, onshore substations, and dedicated port operations and maintenance facilities, anchored by a Fall River, Massachusetts operations office. The company maintains a headcount of 11-50 employees in the current development phase and projects 15,000 direct full-time equivalent jobs at full 2,400 MW buildout.
Revenue mechanics are anchored exclusively by government-administered long-term power purchase agreements with Massachusetts and Rhode Island utilities, structured as multi-year subscription-style offtake contracts with pricing negotiated through competitive procurement and subject to regulatory approval. Pricing terms are not publicly disclosed. The company is pre-revenue, with contracted offtake revenues contingent on reaching commercial operations, and there are no indications of diversification into commercial, industrial, or merchant market channels. Customer concentration is therefore binary: two state-government counterparties representing 100% of contracted capacity.
