About 93% of those still without power across New York State live in the Hudson Valley. A full review as to why it's taking so long for power to be restored is underway.

On Tuesday, Gov. Andrew Cuomo directed the New York State Department of Public Service to conduct a full review into power failures after Winter Storm Riley.

Four days after Winter Storm Riley, 74,790 customers remain without power, 93% are located in Dutchess, Putnam, Sullivan and Westchester counties, officials say.

"The widespread power failures after Winter Storm Riley are dangerous and completely unacceptable, and we will hold these utilities accountable for their failure to quickly restore power to New Yorkers," Cuomo said.

The Department of Public Service will review the utility preparations and response to this storm, specifically targeting those utilities that serve Dutchess, Putnam, Westchester and Sullivan counties.

"This is a severe and prolonged outage, with many thousands of New Yorkers still out, hundreds of impassable roads, and failures of coordination and communications," Public Service Commission Chair John B. Rhodes said. "We will undertake a thorough and intense review, because this response and restoration has not met the expectations of New Yorkers."

According to the governor's office, utility companies have not met the State's expectations and a full-scale review will examine operational failures throughout the restoration process.
