The 2016 update to the states's Clean Energy and Climate Plan had a goal of reducing 1990 baseline greenhouse gas emissions levels by 25% by 2020.
[15] On December 14, 2018, the U.S. Bureau of Ocean Energy Management (BOEM) opened bids for leases on three parcels, each 13,000 acres, located in federal waters south of Martha's Vineyard and Nantucket.
[17] In April 2019, Vineyard Wind was awarded a contract to supply 800 MW of power to Massachusetts utilities at a price of 8.9 cents/kWh and will also spend $15 million on battery systems for energy storage.
[18] They plan to install 84 turbines, with their power line running between the Vineyard and Nantucket to Covell Beach in Centerville, and from there via land to the grid.
[22] Commonwealth Wind (lease area OCS-A 0534)[23] was selected for development in 2021, and signed agreements with all three major Massachusetts electric utilities - Eversource, National Grid, and Unitil.
[25] A Mayflower Wind cable is expected to come ashore at the site of the former coal-powered Brayton Point Power Station,[26] which already has transmission infrastructure.
The Park City Wind project[27] would supply power to Connecticut but land cables in Barnstable on Cape Cod.
The joint venture between Eversource and Ørsted proposed a new design called Revolution Wind 2, to supply clean electricity to Rhode Island Energy.
[30] The New Bedford Marine Commerce Terminal is the first hub in the country designed for the deployment of offshore wind farms.
[31] The terminal is managed by the Massachusetts Clean Energy Center which supports the fabrication and implementation of offshore wind projects and the transportation of large scale marine cargo.
The center offers testing for blades up to 90 meters long and different prototyping methods in order to support the production and installation of land and offshore wind turbines.
[37] In June 2017, Massachusetts utilities issued the first RFP under the energy diversification law signed by Baker in August 2016,[38] and the following month, five major bids were submitted.
[42] In May 2021, the U.S. Department of the Interior announced that a record of decision had been issued giving final federal approval for the Vineyard Wind project.
[53] In 2009, the Massachusetts Department of Energy Resources (DOER) contracted Navigant Consulting to determine new locations of potential wind turbine sites throughout the state.
[55] To meet renewable power minimums and with state approval, Massachusetts utilities agreed to pay for 40% of the output of the proposed King Pine wind farm in Aroostook County, Maine developed by Longroad Energy.
