The cause of the outage, which started at 1:40 p.m., was not immediately known, said Con Ed spokesman Allan Drury, but power was expected to be restored by 9 p.m.
Power had been restored to 200 customers by 4 p.m., said Drury.
City-wide, there were approximately 1,389 customers without power in scattered outages.
Today's high was forecast at 90 degrees by AccuWeather.com. Drury said heat was not a likely cause of the outages and that there were no energy reduction advisories in effect.
"We always encourage customers to use energy efficiently," he said.
