As I sipped coffee and poked through the news early Monday morning, I saw the warning from the Electric Reliability Council of Texas (ERCOT): prepare for rolling blackouts. It wasn’t unexpected. Temperatures have been breaking records left and right across Texas, with Austin’s Camp Mabry sizzling in at 110 °F the day before, beating a record set in 1917 by 5 °F, and San Antonio searing in at 106 °F, beating a previous record by 3 °F set in 2020.

Similar temperatures are expected today, but as a working weekday, electricity consumption is generally higher, so—with everything else being the same—there’s more demand on the grid.
