Some 10,000 Con Edison customers were sweating it out without power as of 6 p.m. Sunday, an outage map provided by the power company showed.
The number was a fraction of that just an hour before, but swathes of Brooklyn began losing electricity just after 5 p.m. — when the heat index reached a blistering 102, according to the National Weather Service, and The Post measured 113 degrees in Times Square.
Just before midnight, Con Edison CEO John McAvoy said in a news conference that all 73,000 customers affected by the outage in Midtown Manhattan and the Upper West Side had power restored. At its peak, the outage affected an area from 71st Street south to 42nd Street and east from the West Side Highway to Fifth Avenue.
New York Gov. Andrew Cuomo added that although service was restored some traffic lights remained out and New Yorkers should stay indoors for their safety.
Police officers were directing traffic at other major thoroughfares. The New York Fire Department said it received reports of people stuck in elevators on the Upper West Side and subway passengers stuck on trains.
Saturday marked the 42nd anniversary of the 1977 blackout, which affected much of the city for 48 hours and resulted in widespread looting, arson and other criminal activities.
An extensive blackout struck Manhattan on Saturday night as power was lost in Midtown, Hells Kitchen and the Upper West Side.
Street lights were reported knocked out on Columbus Ave. on the Upper West Side, and a power outage was also reported in Rockefeller Center around 7 p.m.
ELLWOOD CITY — Power has been restored to a large section of the borough that lost electricity early Friday.
Mark Linville, supervisor of the Ellwood City Electric Department, said a circuit tripped, knocking out power to customers in the Ewing Park area and south side of the community. Power to most was returned within 45 to 90 minutes, he said Friday.
“Everyone is back now,” Linville said.
He said they are not entirely certain what caused the circuit trip, but believe it could be connected to a problem reported at Lincoln High School on Crescent Avenue, which still was without power at 11 a.m. as crews worked on its situation. Inmetco, which is not served by the municipal power company but shares a Penn Power line, also reported an outage. The Ellwood City Medical Center did not lose power because it is on a separate grid, Linville said.
