"will drive up the cost of electricity bills and contradicts everything the administration has told us. It wastes years of state investment in renewable energy designed to diversify our energy supply and lower costs for families and businesses,” said Gov. Ned Lamont in a statement Saturday.

“This arbitrary decision defies all logic and reason. Revolution Wind’s project was already well underway and employed hundreds of skilled tradesmen and women. This is a major setback for a critical project in Connecticut, and I will fight it.” - Sen. Richard Blumenthal
