Vineyard Wind said Sept. 16 that it submitted two proposals to build an offshore wind project off the coast of Massachusetts.
The project, named Commonwealth Wind, is another joint venture between Avangrid Inc. subsidiary Avangrid Renewables LLC and Copenhagen Infrastructure Partners K/S of Denmark. Iberdrola SA is Avangrid’s parent company.
One Vineyard Wind proposal calls for an 800-MW offshore farm, while another calls for 1,200 MW of capacity.
Massachusetts released a request for proposal in May seeking up to 1,600 MW of offshore wind generation to help meet its goal of 4,000 MW of offshore wind by 2027. Electric distribution utility subsidiaries of Unitil Corp., National Grid PLC and Eversource Energy sought the proposals in coordination with the Massachusetts Department of Energy Resources.
In November 2020, the state approved contracts for 804 MW of power from the Mayflower Wind Offshore Project. It is a joint venture of Royal Dutch Shell PLC subsidiary Shell New Energies US LLC and EDP – Energias de Portugal SA subsidiary EDPR Offshore North America LLC. Previously, the state approved contracts for power from the 800-MW Vineyard Offshore Wind Project, which is proceeding with construction after reaching financial close for $2.3 billion in senior debt.
Commonwealth Wind would be developed just south of the Vineyard Wind and the Vineyard Wind South (Park City Wind Offshore) project. President Joe Biden’s administration opened a review of Park City Wind in June.
