Underground cables to connect substations

USA, Massachusetts, Falmouth: Developers presented plans on 16 March for an offshore wind farm in Massachusetts to include underground cables.

The joint venture between Shell and EDP Renewables to develop an 804 MW wind farm in Falmouth was presented to the Board of Selectman, Cape Cod Times reported.

Plans for the Mayflower Wind project show the energy generated from the wind turbines will travel through underground cables to an offshore substation on the Atlantic Coast Outer Continental Shelf to another substation onshore.

The onshore substation will be set in Falmouth because of the necessary path of the transmission route, according to Christopher Hardy, external outreach manager for Mayflower Wind.

“There would be three cables making their way from the wind farm, 48 km (26 nautical mi) off the coast of Nantucket,” Hardy said. “The cable route would go through Nantucket Sound all the way into Falmouth, making landfall onshore.”

John Harnett, who is overseeing the project, said that from there the power will travel through overhead lines to an interconnection switching station and then to a transmission system in Bourne, where the energy will interconnect with the electric grid.

It is still unclear where the landing spot in Falmouth will be located.

The development of the project will help the state continue on its way to meeting the goal set by Gov. Charlie Baker’s Energy Diversity Act of 2016. The act requires that electric distribution companies purchase 1,600 MW of power from offshore renewables by 2027, along with 1,200 MW of clean power. The project is expected to create 10,000 jobs in the region as well as eliminate 1.7 M t of carbon dioxide emissions annually.
