In a rare move for the winter, Consolidated Edison is asking some Manhattan residents to conserve energy.
The affected area runs from West 153rd Street on the north to West 131st Street on the south, and Riverside Drive on the west to Broadway on the east.
In Midtown the affected area extends from West 52nd Street on the north to West 39th Street on the south, and Broadway on the west to Fifth Avenue on the east.
Over 10,000 customers are affected by these restrictions.
Con Ed made the request after three feeder cables went down in parts of West Harlem when melted snow and salt got into the electric system.
Residents are being asked to avoid using washing machines, dryers and dishwashers.
They should also shut off their lights where possible.
Con Ed says even a normal level of electric use could overwhelm the system and lead to outages.
The company says the request to conserve energy is temporary and will last until the feeders are fixed.
