ALBANY, N.Y. (AP) — New York Gov. Andrew Cuomo on Tuesday ordered an investigation into how utility companies prepared for and reacted to Superstorm Sandy, which knocked out power to more than 2 million customers and left some without electricity for two weeks and counting.

Cuomo ordered the probe under the state’s powerful Moreland Commission law that provides for subpoenas and other action. He previously had threatened to hold public hearings on his concerns and has repeatedly criticized the utilities for what he considers slow progress restoring power to customers from Long Island to the Hudson Valley.
