New York City Power Restored Hours After Outage
NEW YORK—A power outage struck the heart of Manhattan on July 13, the anniversary of a 1977 blackout—stranding passengers on subways, gridlocking drivers that had to navigate the streets without traffic lights, and bringing the curtain down on Broadway shows.The outage, which stretched 30 blocks from Times Square to the Upper West Side, left around 73,000 customers without power for about four hours.

Con Edison CEO John McAvoy said a problem at a substation caused the 6:47 p.m. power failure. Electricity was restored to customers and businesses affected by the outage by around midnight, according to a statement from the utility.
McAvoy said the exact cause of the blackout would not be known until an investigation is completed.
The outage stymied subway service throughout the city, affecting nearly every line. New York City's Emergency Management Department said the A, C, D, E, F, M, 1, 2, 3, 4, 5, 6 and 7 trains had resumed running in both directions by around 2 a.m. Sunday.
