Connecticut Attorney General George Jepsen says he’s still not totally thrilled with the performance of the state’s largest utility following the freak October snowstorm of 2011, or how the company responded to the state evaluation.

Still, Jepsen says he’s closing his investigation into Connecticut Light & Power after CL&P’s parent company, Northeast Utilities, agreed to donate $2.5 million to Operation Fuel, a nonprofit which provides heating assistance and financial help for energy-saving initiatives.
