December 20, 2021 — The amount of offshore wind power in the Massachusetts pipeline is poised to roughly double with the selection Friday of projects from both Vineyard Wind and Mayflower Wind to cumulatively generate 1,600 megawatts of cleaner power for the Bay State by the end of this decade.
A group of utility executives working with assistance from the Baker administration was seeking 1,600 MW more of offshore wind power but got just two bids that each maxed out at 1,200 MW and came only from the two developers already under contract to deliver offshore wind power to Massachusetts. So instead of picking just one 1,200 MW project, the group selected Vineyard Wind’s roughly 1,200 MW Commonwealth Wind proposal and supplemented it with a 400 MW project offered by Mayflower Wind.
Both developers are already working on roughly 800 MW projects for Massachusetts. Vineyard Wind I, the first utility-scale offshore wind farm in the nation, is in the very early stages of construction and is due to come online by the end of 2023. Mayflower Wind’s initial 804 MW project just began its federal review process and is expected to be up and running in 2025.
“These projects will double the size of our current offshore wind procurements, they will deliver significant economic benefits to a number of coastal communities across the commonwealth, they include important provisions for diversity, equity and inclusion as well as benefits to environmental justice communities, and they invest significantly in the state while balancing protections with environmental resources including fisheries,” Energy and Environmental Affairs Secretary Kathleen Theoharides told the News Service on Friday.
