The utility has completed ERCOT winter preparedness requirements to meet energy demand.  

December 15, 2023 (SAN ANTONIO) – As part of the Electric Reliability Council of Texas (ERCOT) winter readiness efforts, utilities across the state are required to certify that winter preparedness activities have been completed by December 1, 2023. CPS Energy submitted the required Declaration of Preparedness for winter weatherization to ERCOT for the utility’s transmission systems and power plants.  

As part of the declaration, CPS Energy notified ERCOT of four power plants that are offline for planned winter maintenance. Three units are scheduled to return to service on or before December 15, 2023, with one remaining unit expected to return by early January.  Power plant planned maintenance outages are necessary to prepare for reliable operations.  

Compliance certifications were completed in addition to weatherization efforts for the utility’s power plants. Weatherization activities protect critical power plant equipment from freezing temperatures. CPS Energy installed more than 100 temporary and permanent enclosures to safeguard essential equipment and added other measures such as the placement of supplementary heaters, protective barriers, thicker insulation, emergency backup generators, and other protections totaling more than $20 million since February 2022.
