Bay State Offshore Wind Transmission System
The Bay State Offshore Wind Transmission System will collect energy from multiple offshore wind farms and deliver it to shore. The Massachusetts system will initially consist of two independent, radial, generator lead lines originating in the waters south of Martha’s Vineyard, connecting to the existing grid near Massachusetts southern coast.
Each radial line will include an offshore collection platform with a DC VSC converter station, approximately 50 miles of undersea cable, and an onshore converter station. The initial system will be designed to transmit 2000 MW of power, with each converter station pairing sized to transmit 1000 MW. This system can be developed in phases and can be sized appropriately to market demand.
The first phases of the Bay State Offshore Wind Transmission System will be designed so each converter station pairing will be independent of the others. As DC networking technology advances, the offshore platforms could be connected to create an offshore network.
