A blackout plunged New York City into darkness
On this day · 13 July 1977
Lightning, a fragile grid, and a sweltering night left eight million New Yorkers in the dark for roughly a day in 1977.
On the night of July 13, 1977, lightning struck Con Edison transmission equipment north of New York City. In a sweltering, humid summer, the strikes tripped circuit breakers and toppled power lines faster than operators could compensate.
Within about an hour the utility’s entire system collapsed, and the lights went out across all five boroughs. Unlike the orderly 1965 blackout, this one fell on a city strained by recession and heat, and the darkness turned chaotic.
Firefighters battled over 1,000 fires while looting swept several neighborhoods; roughly 4,000 people were arrested before order returned. A federal Department of Energy assessment later studied the economic and social damage in detail.
Power was not fully restored until the following day, after some 25 hours of darkness.
The failure exposed how brittle a dense city’s grid could be, and it pushed utilities and regulators toward tougher reliability standards for the years ahead.
