Con Edison has asked thousands of customers in parts of the Bronx and Upper Manhattan to conserve energy while crews repair equipment in the area.
The utility has reduced voltage by 8% in the affected areas to protect equipment and maintain service while repairs are underway.
In the Bronx, approximately 39,600 customers are affected in an area that includes parts or all of Riverdale, Marble Hill, Kingsbridge and Van Cortlandt Park. The affected area stretches from the Westchester County line to the Harlem River and from the Hudson River to Sedgwick Avenue and the Bronx River.
In Manhattan, approximately 75,200 customers are affected in Inwood, Hudson Heights and Washington Heights. The area stretches from West 155th Street north to the Harlem River and from the Hudson River east to the Harlem River.
Con Edison has asked customers in the affected neighborhoods to avoid using energy-intensive appliances, including washers, dryers and microwaves, until repairs are complete.
Customers have also been asked to limit unnecessary air conditioning use. Those with two air conditioners should use only one and set it to the highest comfortable temperature.
The utility has also asked customers to avoid charging electric vehicles in the affected neighborhoods unless necessary while repairs are underway.
Con Edison said the equipment problems are not affecting the rest of its system.
