Just before 9am Saturday, ERCOT's reserve electrical capacity was just 89 megawatts. ERCOT electricity usage may set a winter record this weekend due to a 5-day long stretch of extremely low temps across the state.
Weekend low temperatures in the single digits, and in some cases below zero, are expected to contribute to record high electricity use in parts of Texas. Especially in the part of West Texas that is served by ERCOT.
