New Jersey power company Public Service Enterprise Group Inc (PSEG) will take seven to 10 days to restore power to all its customers after the tidal surge from monster storm Sandy badly damaged the electric transmission system and some switching stations, CEO Ralph Izzo said on Thursday.

"Probably the most significant damage we sustained was due to a tidal surge that was associated with Hurricane Sandy that hit the northern part of the territory, and uniquely did some damage to our transmission system and some of our switching stations," said Izzo, the chairman, president and CEO of PSEG, on the company's third-quarter conference call.
