NYC utility: Some power outages due to superstorm Sandy could last up to a week

NEW YORK (AP) - New York City's utility company says it could be anywhere from several days to a week before residents who lost power during the superstorm get their lights back.

Consolidated Edison says it's dealing with several different issues -- downed overhead lines, a planned shutdown of underground networks and an unexpected explosion at a substation that darkened a large part of lower Manhattan.

Senior Vice President John Miksad says the planned outage should take three to four days to restore, while the explosion and the downed lines could take up to a week.

The company said 670,000 customers are without power in New York City and Westchester. A customer is an individual meter, so the number of actual people affected is likely higher.
