Offshore wind developer consortium Mayflower Wind has upped the stakes in the US state of Massachusetts’ third round request for proposals (RFP) with “multiple bids” of up to 1.2GW, sweetened by more than $80m in planned local investment, infrastructure, and jobs creation.

Coming on the heels of rival Vineyard Wind’s announcement of its like-sized 1.2GW Commonwealth Wind, the bids by Mayflower Wind add to its existing commitment to construct 804MW in the Atlantic waters off Nantucket, and features an arrangement to land power production at the grid connection previously used by the now-decommissioned coal-fired plant at Brayton Point.
