Ten wind turbines in the planned Cape Wind offshore project will be relocated after it transpired that a rock outcropping meant that Massachusetts state boundaries extend further off the mainland than previously thought. The new boundary put some of the Cape Wind project within state lands, which would have added a layer of complexity to an already complicated application. The project developers will also shift an additional 20 turbines in response to comments over potential impacts to commercial fishing, navigation and archaeological sites. As a result of the two changes, the 130 turbine, 468 MW project will leave a smaller footprint. The project -- first proposed nearly three years ago -- has faced intense opposition from landowners, especially in the Horseshoe Shoals region of Nantucket Sound just south of Cape Cod. The winds in Nantucket Sound are some of the best on the East Coast, making it a favourite wind surfing destination and the relatively shallow waters on Horseshoe Shoal, in the middle of the sound, make it a desirable site for wind turbines.
