Con Edison crews – working around the clock – have restored electricity to more than 225,000 customers since Hurricane Sandy's departure.

The hurricane is the worst natural disaster to strike Con Edison's customers.

Safety for customers, Con Edison employees, and contractors is the No. 1 priority. Crews still face hundreds of wires down in New York City and Westchester County, where more than 600 roads are closed. Trees also block access to wires and equipment throughout the system and hundreds of vaults are flooded.

The company expects to make significant progress restoring electricity over the next two days due to Wednesday's damage assessment and field work planning. Additional crews from around the country continue arriving from as far away as California to assist New Yorkers. Cargo planes are unloading their equipment and will be assigned throughout the area.

Con Edison restored power on Wednesday to customers served by two underground electrical networks that were taken out of service Monday night as the floodwaters from Hurricane Sandy were surging.

One network is in lower Manhattan and serves 2,000 customers. The customers are in an area bordered by Vesey Street on the north; West Street; Broadway and State Street on the east; and the Battery's southern tip.

The second area is Con Edison's Brighton Beach network, serving about 28,200 customers and includes Coney Island, Seagate, Brighton Beach, Manhattan Beach, and Sheepshead Bay.

The utility noted that although it has restored power to the networks, some buildings may still be without electricity due to basement flooding or damage to local equipment.

As of 4:30 a.m. yesterday, Con Edison reported approximately 676,000 customers out of service. That included 227,000 in Manhattan, 103,000 in Queens, 59,000 in Brooklyn, 83,000 in Staten Island and 36,000 in the Bronx. In Westchester County, the company reported 166,000 customers out of service.
