The heatwave currently blanketing two-thirds of the United States with record-setting temperatures is straining the nation’s power system.
On Monday, Con Edison, New York City’s power provider, urged residents to conserve electricity. It reduced power voltage to the borough of Brooklyn by 8 percent as it made repairs; it did the same to areas in the boroughs of Staten Island and Queens yesterday. Thousands also lost power as the grid could not handle the strain.
