Alamo City Battery Energy Storage Project Begins Construction

On May 19, 2026, OCI Energy and CPS Energy celebrated the groundbreaking of the Alamo City Battery Energy Storage Project in southeastern Bexar County. This project is poised to be one of the largest standalone battery energy storage initiatives in the region, designed to bolster the power supply reliability for the San Antonio area during times of high electricity usage.

The Alamo City BESS will consist of a 120 MW / 480 MWh facility capable of powering approximately 30,000 homes for up to four hours. This innovative energy storage system aims to deliver crucial support to the electric grid during peak demand periods, thereby enhancing the overall efficiency and economics of electricity distribution.

A Progressive Step for San Antonio

"This project represents a significant step forward toward realizing a more resilient, reliable energy system that San Antonians can be truly proud of," stated Sabah Bayatli, President of OCI Energy, during the groundbreaking ceremony. He emphasized that this marked the transition from the planning phase to actual construction, reflecting years of coordination and hard work.

The collaborative effort behind the project includes ING, which provides construction financing, LG Energy Solution Vertech, which is supplying the battery technology, and Elgin Power Solutions, acting as the Engineering, Procurement, and Construction contractor. This teamwork not only involves substantial investment but also paves the way for durable infrastructure supporting Texas's energy system during high-demand periods.

Enhancing Grid Resilience

Rudy Garza, President and CEO of CPS Energy, highlighted the crucial role of energy storage in preparing for the future. "Projects like Alamo City BESS give us the flexibility to meet growing demand, integrate diverse energy resources, and ensure our community has reliable power when it matters most," Garza said.

The Alamo City BESS aims to change how and when electricity is supplied, thereby optimizing operations during peak loads. By providing additional flexibility and control, the project is expected to improve overall grid reliability.

Construction Timeline

Once operational, the facility is anticipated to commence commercial operations in 2027, effectively enhancing power availability during critical times. This timeline reflects the commitment of OCI Energy and its partners to swiftly bring this necessary infrastructure to life for the San Antonio community.

The groundbreaking of the Alamo City Battery Energy Storage Project represents a forward-thinking approach to energy resilience, addressing not only current needs but also future demands as energy consumption continues to rise. As communities face growing challenges related to power supply and reliability, projects like Alamo City BESS will play a pivotal role in shaping a sustainable energy future.
