The Cape Wind Project

The size and location of Cape Wind would make it a major threat to the safety of air and sea travel in and around Nantucket Sound. Further, it would devastate commercial fishing in the Sound, desecrate a national treasure and sacred Tribal lands, and threaten endangered birds and marine mammals. All this AND Cape Wind would impose a $3 billion electric rate hike on Massachusetts ratepayers.Cape Wind is a private developer seeking to build an industrial scale offshore wind power plant on Horseshoe Shoal in Nantucket Sound. The for-profit developer chose this location without public input, based solely on technical criteria to maximize profit.

Covering 25 square miles, an area the size of Manhattan, the plant would consist of 130 wind turbines, each standing 440' tall - significantly larger than the Statue of Liberty (305') and the Cape Cod Canal bridges (275'). The diameter of the massive blades would be 364 feet. Imagine a rotating football field.
There would be a total of 68,000 gallons of oil in the complex: 40,000 gallons of electric insulating oil and 2,000 gallons of diesel and other oils from the Electrical Service Platform and up to 200 gallons of turbine and other lubricating oils from the gearboxes of each of the 130 wind turbine generators.

At night the project would look like LaGuardia Airport, complete with flashing red and amber lights, urbanizing the night-time sky.

There will be two different kinds of lighting:

  1. FAA Lighting at the top of the masts Single flashing red lights on 50 perimeter turbines and 8 turbines adjacent to the ESP. Syncronized flashing at 20 per minute -- one second on, two seconds off.
  2. USCG Lighting– Marine Navigational: Two synchronized flashing amber lights on the ESP (Electrical Service Platform) and on each turbine about 35 feet above the water surface.







The map below shows location of the proposed project, which would be in federal waters (shaded yellow), surrounded by state waters. This yellow area in the middle of Nantucket Sound is sometimes referred to as the "doughnut hole."




 The plant would also include a 10-story electrical service platform (ESP), 1/2 acre in size, holding 40,000 gallons of transformer oil and 1000 gallons of diesel fuel, with a helicopter pad on top.
