Con Edison said there appears to be no power outage on the Upper East Side, despite reports on social media.
"No outages reported, but we had a voltage disturbance from a transmission line that went out. System okay," ConEd spokesman Mike Clendenin said.
Clendenin said people may have noticed a dip Friday afternoon.
The utility will continue to check for outages, but "so far nothing yet," Clendenin said.
There were a number of reports on social media of people stuck on elevators because of the possible outage.
