But this was not the first time that a major power outage hit the city on exactly the same date. In 1977, at the beginning of a sweltering heat wave, a 25-hour blackout ruined the city.
During the blackout decades ago, people didn't help drive traffic and accelerate it, as they did on Saturday. At that time, the fury of a crime broke out as people filled the dark streets, looted and set fire to the shops.
Within a day, there were nearly 3,000 arrests, a study commissioned by the Electric Energy Systems division and the Energy State Department.
"In the areas most affected by looting and vandalism, the large amount of waste, garbage and spoiled food required the addition of 82 sanitary trucks and 4,000 workers to deal with the cleaning operation," says the study.
Then, the system collapsed for several reasons
The 1977 blackout was caused by a combination of events.
The thunderstorms that rained on the city that night triggered malfunctions in the Con Edison system, which eventually darkened. The Con Edison system has collapsed from a combination of natural events, equipment malfunctions, questionable system features and operational errors, according to the Federal Energy Regulatory Commission.
That blackout had an estimated cost of $ 350 million, according to the study.
