Electricity use in Texas soared to a record high for the ninth time this year as extreme heat and the rapidly growing local economy tests the state’s grid.

Demand rose to more than 78.9 gigawatts during the hour ending at 5 p.m. Central time, according to the Electric Reliability Council of Texas, which operates the system. Ercot demand had previously set new highs eight times over five weeks, with the most recent peak of 78.4 gigawatts on July 12.
