Temperatures in Houston this week will feel as hot as 112 F (44 C). The combination of heat and humidity will drive up energy demand to more than 74,900 megawatts (MW) on Monday and almost 75,000 MW on Tuesday. The all-time high is 73,473 MW on July 19, 2018. Grid operator, ERCOT, may encourage conservation but don’t expect rates to rise with the temperature.
