Much of Midtown and the Upper West Side on Saturday night went dark after a power outage hit and cut power to the residents of Manhattan.

Saturday night’s power outage occurred on the 42nd anniversary of a New York blackout on July 13, 1977 during a heat wave.

Reuters reported that a blackout hit more than 40,000 people Saturday evening sending Manhattan into chaos when subway stations and restaurants went dark.

An apparent transformer explosion on the Upper West Side caused the blackout.

Reuters reported:

A Reuters witness in the area reported hearing an explosion at about 7 p.m. (2300 GMT), and a New York City Fire Department spokesman said firefighters were on the scene of a transformer fire. “Members are responding to reports of numerous stuck elevators that are occupied, but there are currently no patients reported,” the department said on Twitter. It said the outage extended from Fifth Avenue west to the Hudson River, and from the west 40s north to 72nd Street. The Con Edison utility said it was working to restore power to 42,000 customers and would provide updates as it got them.
