ERCOT readiness efforts

The Electric Reliability Council of Texas (ERCOT)’s new winter readiness efforts required operators across the state to certify compliance of winter weather readiness for generation units and transmission systems by December 1, 2021. In our formal response to ERCOT on November 30, 2021, CPS Energy reported all transmission systems and 12 generation units (11 thermal units and 1 battery storage site) as fully compliant.

Last week, 8 units returned from planned outages. This week, two additional units, Braunig 1 and Spruce 1, have returned from planned outages and are in compliance with our winter readiness program, resulting in a total of 22 units that are now fully compliant with ERCOT’s Winter Weather Readiness Report (WWRR). Braunig -VHBCT8 will remain in a forced outage until early January 2022 to address items discovered during a planned inspection in mid-October 2021. When this unit returns to service, we will formally notify ERCOT and continue to share updates with our community.
