More than half of Public Service Electric and Gas customers in Teaneck were without electricity after an original company estimate said service would be restored by late Saturday night.
According to an updated work schedule available on Gov. Chris Christie's office website Sunday morning, 9,141 of the town's 15,892 customers were out.
PSE&G says in the document it estimated to have 4,113 customers back Sunday and 4,571 Monday.
The updated information differed from data posted on PSE&G's website earlier Saturday showing 8,019 customers out. A PSE&G spokesman did not immediately respond to a message seeking details Sunday morning.
A spokesman for the NJ Board of Public Utilities told Patch that the restoration expectations were projections and subject to change due to "unforseen circumstances."
More power was restored in Teaneck on Friday and Saturday, including to many Cedar Lane businesses and a section of Teaneck Road.
In a statement Saturday night, PSE&G said it had restored power to "many neighborhoods" but occasionally needed to shut down circuits to make further repairs.
"The significant progress we’ve made on the transmission system means we’re now increasingly focusing our efforts on our distribution system. This means that our work will be more visible in your neighborhood," the company said.
Teaneck was one of 14 Bergen County towns where the PSE&G said utility crews were focused over the weekend.
PSE&G was also running a mobile customer service center at the Paramus Park Mall from 8 a.m to 9 p.m., offering water, ice and charging stations.
The company asked residents to report any outages by calling 1-800-436-7734.
