ERCOT electricity demand and production in February 2021

Texas has suffered major disruptions to its electricity supply due to storm Uri sweeping the United States from February 14, 2021. The state's largest independent system operator, the Electric Reliability Council of Texas (ERCOT) was unable to deliver electricity to over four million customers, as extreme cold temperatures resulted in many power plants having to be shut off. ERCOT manages roughly 90 percent of Texas' electric load, serving 26 million customers. Between February 15 and 17, the difference between day-ahead forecasts for electricity demand and electricity generation was particularly pronounced.
