Last week, the long-embattled Cape Wind project got a break: Utility NStar(NST) agreed to buy 27.5 percent of the proposed offshore wind project's output. Together with a previous power purchase agreement with National Grid (NGG), this gives Cape Wind a buyer for 77.5 percent of the project's total projected output. Jim Gordon, Cape Wind's President speaking at Offshore Wind Power USA in Boston, called the NStar deal the "starting gun" for Cape Wind's financing round.
