(Reuters) - U.S. offshore wind farm developer Cape Wind said on Monday that Massachusetts utility regulators approved a 15-year power purchase agreement with power company NSTAR to buy Cape Wind's energy, capacity and renewable energy credits.
NSTAR is a unit of New England power company Northeast Utilities.
The NSTAR purchase agreement approved by the Massachusetts Department of Public Utilities (DPU) covers 27.5 percent of Cape Wind's power, Cape Wind said in a release.
