Longtime opponents of the controversial Cape Wind project are again challenging the proposed offshore wind development in court, saying the state overstepped its authority when it brokered an agreement for the utility NStar to purchase power from the offshore wind project.
The Alliance to Protect Nantucket Sound — Cape Wind’s biggest detractor — the town of Barnstable, and three Cape Cod businesses filed suit in US District Court in Boston Tuesday, alleging that the state discriminated against out-of-state power companies by pressuring the Boston utility to buy power from Cape Wind. The suit alleges that NStar agreed to buy power from Cape Wind, rather than lower cost sources, to gain approval from Massachusetts regulators for its merger with Northeast Utilities, which was finalized in April 2012.
