The cause of the outage was unclear, McAvoy said, adding "it does not appear related to excessive load". The blackout also affected a number of Broadway productions including "Harry Potter and the Cursed Child", "Hadestown", "Lion King", "Ain't Too Proud", "To Kill a Mockingbird", and "The Cher Show", which were all canceled. The lights of nearby Radio City Music Hall were dark.
Performers of shows such as "Hadestown" and "Hamilton" took their shows outside and began performing in the streets of NY in an attempt to appease the disappointed masses.
Street lights and traffic lights have been put out of action.
Police officers and civilians worked together to direct traffic while firetrucks and ambulances screamed down side streets.
Saturday's outage occurred on the 42nd anniversary of a NY blackout that crippled the city during a heat wave on July 13, 1977. Power was not restored until the next day.
Memories of rioting, looting and violence during the 1977 blackout spooked some tourists visiting the city, including Dave and Dara Campbell, of Gilbert, Arizona. At first she thought something happened at Trump International Hotel and Tower, she said.
"We are responding to extensive outages on the west side of Manhattan", said Con Ed spokesman Michael Clendenin told the New York Daily News.
Fox News foreign desk director Greg Headen was settling in for a movie at an AMC theater on the Upper West Side when the power went out and staff members called for everyone to evacuate.
Power utility ConEdison reported that tens of thousands of people were without power, and many subways have gone dark. "It sounds like it is addressable in a reasonable amount of time".
"We were stuck for about 75 minutes", said O'Malley, 57.
