ALBANY, N.Y. (AP) — The utility companies Consolidated Edison and Long Island Power Authority confirmed Wednesday they received subpoenas from the state attorney general and were cooperating with his investigation into their preparation for and response to Superstorm Sandy.

An official familiar with the investigation said Attorney General Eric Schneiderman seeks plans and performance records on restoring power, communicating with customers without power and other aspects of the utilities’ responses to the storm. The official wasn’t authorized to speak during the investigation and requested anonymity.
