Two Cuomo administration officials confirmed the Long Island Power Authority appointment of Lawrence Waldman on Tuesday. The officials spoke to The Associated Press on the condition of anonymity because a formal announcement hadn't been made.
More than a million customers lost power after the October storm. Some remained in the dark for more than two weeks.
Waldman's appointment is meant to stabilize LIPA (LY'-puh) while the probe continues.
Waldman is a LIPA trustee and chairman of its board's finance and audit committee. He replaces Howard Steinberg, whose resignation in November followed those of LIPA's chief operating officer, a trustee and a vice president of customer service.
Cuomo also appointed RXR Realty president Michael Maturo as a LIPA trustee.
