The punishing heat dome that has settled over Texas is putting unprecedented strain on the state’s electricity system, leaving officials scrambling to keep the lights on and the air conditioners cranking.

The oppressive heat has endured for days, and it may get worse before the heat dome lifts. Some forecasts show temperatures soaring past 100 degrees in all three major metropolitan areas — Houston, Dallas and Austin — at once in the coming days. Tens of millions of people in Texas and nearby states have been under extreme heat advisories since June 14.
