The president of the company developing the Cape Wind project said today that he hoped that the controversial offshore wind farm could begin generating power within a year, now that the company has received a favorable decision in the state’s highest court. “Today is a really big day for Cape Wind, but it’s an even bigger day for clean energy in Massachusetts,” said Jim Gordon, whose company hopes to build a field of whirling wind turbines in Nantucket Sound. “This moves the project forward.” Gordon commented after the Massachusetts Supreme Judicial Court gave its blessing to a novel power purchase agreement between Cape Wind and National Grid that was approved by the state Department of Public Utilities.
