Con Edison announced last Monday that the cause of a blackout affecting more than 70,000 residents in Manhattan on Saturday, July 13 was due to a malfunction at the West 65th Street substation.

The outage, which occurred at 6:47 p.m., affected customers from West 30th Street to West 72nd Street between Fifth Avenue and the Hudson River. The six electrical networks that were affected were back in service shortly before midnight on Sunday.

Con Edison said that their inspection of equipment and review of the system data found that the relay protection system at the substation didn’t operate as designed. The relay protection system is designed to detect electric faults and directs circuit breakers to isolate and de-energize the faults but in the case of the outage, the systems did not isolate a faulted 13,000-volt distribution cable at West End Avenue and West 64th Street.

The utility had initially ruled out the 13,000-volt cable fault as the cause, believing that it was unrelated to the transmission disturbance.

“The rodent somehow managed to make its way into a substation in Lancaster, a Buffalo suburb, Sunday, knocking out three substations, New York State Electric and Gas said,” the News wrote. Fortunately, for the residents in the area, power was restored three hours later.

But with the threat of more extreme wintry weather ahead this weekend, Town & Village turned to Con Ed to ask about the possibility of such a thing occurring in a certain Manhattan neighborhood that has not only a power plant but an abundance of Eastern Greys scurrying about.
