TRENTON - Utility crews are still working to restore electricity to close to 27,000 customers nearly a week after Hurricane Irene reached New Jersey.

The storm knocked out power to more than 1.5 million customers in the Garden State.

Jersey Central Power & Light says the majority of the remaining 26,000 customers will be restored by Saturday. The largest number of customers who will be out through Sunday are in the hardest-hit areas of Monmouth, Morris, Hunterdon, Sussex, Passaic and Warren counties.

PSE&G has restored service to more than 800,000 customers. The utility says that 300 outages remain. Many of the remaining outages are what the utility calls "isolated complex problems." Examples would be trees that knocked down power lines. Restoration in Middlesex, Somerset and Union counties is expected by Saturday at midnight.

Atlantic City Electric has 118 customers still without service.

The companies say outage numbers tend to fluctuate after a large storm because they often have to turn off power briefly to some customers as they make repairs.
