Power outages were reported throughout Long Island and New York City on Sunday as the region dealt with sweltering heat.
The Long Island Power Authority reported more than 1,500 customers were without power Sunday evening, with more than 50 active outages in Nassau and Suffolk counties. By midnight, the number without power had been reduced to around 400.
A LIPA spokeswoman said there was no indication the outages were heat related and the utility generally had lines up within the hour.
"We have not received word that we have to tell customers to not run their ACs [air conditioners]," the spokeswoman said.
Con Edison officials said they "set an all-time peak usage record for a Sunday," hitting 11,283 megawatts at 6 p.m. The previous Sunday record was 10,866 megawatts on Aug. 14, 2005.
In New York City and Westchester County, Con Ed reported more than 500 customers without power as of 6:30 p.m., with 50 active outages.
"When it's this hot, there's invariably going to be some strain on the electrical system," said Con Ed spokesman Bob McGee.
In Staten Island, power was mostly restored to the 61,000 customers left powerless on Saturday due to a manhole fire Friday night, McGee said, but the company was still advising customers to "use energy wisely."
