On October 21, 2021, the Public Utility Commission of Texas (PUCT) approved a rule that creates requirements for power companies to better prepare for winter weather. The rule stems from the Texas Legislature’s passage of Senate Bill 3 (S.B. 3) in response to the devastation caused to the energy grid by Winter Storm Uri.
S.B. 3, effective June 8, 2021, is a multi-pronged law that attempts to make the Texas energy system more resilient to the effects of extreme winter weather events.

The new rule, codified as 16 Texas Administrative Code §25.55, requires electric generators and transmission service providers (TSPs) (collectively, generation entities) to implement the winter weather readiness recommendations identified in the 2012 Quanta Technology Report on Extreme Weather Preparedness Best Practices and the FERC/NERC 2011 Report on Outages and Curtailments During the Southwest Cold Weather Event on February 1-5, 2011. The rule also requires affected entities to fix any known, acute issues that arose from winter weather conditions during the 2020-2021 winter weather season. The deadline for implementation of many components of the new rule is December 1, 2021. Continue Reading
