CPS Energy Initiates Proposal for Expanding Battery Storage Capacity by 500 MW

CPS Energy, a public utility based in San Antonio, is taking a significant step in energy resource management by issuing a Request for Proposal (RFP) aimed at acquiring an additional 500 megawatts (MW) of battery storage capacity. This initiative marks an important component of the utility's Vision 2027 Generation Plan, which is designed to provide affordable, reliable, and sustainable energy solutions for the rapidly growing community in San Antonio.

The proclamation was made on December 15, 2025, with Rudy D. Garza, the President and CEO of CPS Energy, emphasizing the utility's commitment to modernizing its energy portfolio. Garza highlighted, "This request to add more battery storage to our generation portfolio continues to fulfill our promise to deliver on the utility's Vision 2027 Generation Plan." This strategic move is part of an ongoing effort to keep pace with the increasing demand for energy resulting from community growth.

Once the RFP is completed, CPS Energy anticipates reaching a collective battery storage capacity of over 1,000 MW, building upon the already operational or contracted storage facilities. To date, the utility has successfully deployed 50 MW of storage capacity under the same vision plan, with a further 470 MW anticipated to be operational by 2026. This progressive strategy aligns closely with the utility's commitment to the City of San Antonio's Climate Action and Adaptation Plan (CAAP), which aspires for carbon neutrality by the year 2050.

The RFP process is expected to play a crucial role in diversifying CAMPS Energy’s generation resources while ensuring they meet environmental and social commitments. With a proposal submission deadline set for January 30, 2026, at 11:45 PM Central Time, organizations and contractors interested in participating in this opportunity must prepare their submissions through the Power Advocate Portal.

This initiative is not just about increasing capacity; it embodies CPS Energy's dedication to transforming its energy landscape and promoting sustainability within the community. By enhancing their battery storage capabilities, the utility is poised to efficiently adapt to energy fluctuations and supply-demand challenges, ultimately benefitting its customers.

CPS Energy, founded in 1860, holds the distinction of being the largest public power provider in the United States, serving more than 970,000 electric and 390,000 natural gas customers across San Antonio and several surrounding counties. The ongoing advancements in their energy strategy showcase the utility's commitment to ensuring low energy bills while contributing to economic growth and educational investments within the region. As the utility continues on this path, it underscores a broader vision of sustainable development that balances community needs with climate responsibilities.
