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.

Comparable outages have been felt around much of the East Coast and Midwest including in the states of Virginia and New Jersey. In Philadelphia and Cleveland, power went out for thousands of customers after severe thunderstorms late last week, and has yet to be restored as the region faces high temperatures.
