HARTFORD, Conn. (AP) — Connecticut Attorney General George Jepsen released documents on Tuesday that he said demonstrates that the state’s biggest utility knew it could not keep a promise to restore nearly all electricity following an October 2011 snow storm that cut power to hundreds of thousands of customers for up to 11 days.

Jepsen is asking the Public Utilities Regulatory Authority to cut CL&P’s request for $175 million in higher rates over six years.
