Consolidated Edison (Con Ed) said its costs related to Hurricane Sandy damage and recovery could climb as high as US$450 million. The utility said it used its experience with Hurricane Irene in August 2011 — previously the largest storm in the company's history — as a basis for the estimates, but said Sandy caused five times as many outages as Irene.

A record storm surge across the Northeast, including in New York City, caused flooding and widespread damage to much of Con Edison's underground electrical equipment. In areas with overhead power lines, workers had to contend with more than 100,000 downed wires, blocked roads and flooding.
