Cape Wind is nearing construction to become America’s first offshore wind farm.
Cape Wind will produce 75% of the electricity used on Cape Cod and the Islands of Martha’s Vineyard and Nantucket in average conditions, with zero pollutant emissions, zero waste discharge, and zero water consumption.
Cape Wind will help launch the American offshore wind industry and produce significant economic, environmental, and energy benefits for Massachusetts, the region, and the nation.
Cape Wind will consist of 130 Siemens 3.6-megawatt offshore wind turbines with a capacity of 468 megawatts. The project will be located in Federal waters off the coast of Cape Cod, Massachusetts, on Horseshoe Shoal in Nantucket Sound, the most technically optimal offshore wind power site in the United States.
Cape Wind’s monopile foundations are individually designed and will be driven deep into the seabed to support the wind turbines. Transition pieces will be fitted onto the monopiles. The wind turbine towers will be bolted onto the transition pieces. Intra array submarine cables will be jet plowed six feet into the seabed and will feed into an Electric Service Platform (ESP) near the center of the wind farm array. From the ESP, export submarine cables will be submerged and make landfall in West Yarmouth, where buried cables will continue to the interconnect point, the Barnstable Substation.
Cape Wind’s Operations Headquarters will be based along Falmouth Harbor on Cape Cod.
