A Memorandum of Understanding (MOU) was signed yesterday, May 26, 2025, by Texas-based OCI Energy LLC (OCI Energy), CPS Energy, and LG Energy Solutions’ U.S. energy storage division, LG Energy Solution Vertech, to commemorate their partnership on the Alamo City Battery Energy Storage System (Alamo City BESS) project. In a ceremony held in Seoul, South Korea, the home base of OCI Energy and LG Energy Solution Vertech’s parent companies, the partnership was officially announced. It is a major step forward in grid strengthening infrastructure that will improve energy security and dependability for San Antonio, Texas, businesses and residents.
According to the MOU, OCI Energy, the project developer, will get the battery energy storage system and energy management technologies from LG Energy Solution Vertech. As the off-taker, CPS Energy would agree to buy energy storage capacity through a deal that would be arranged with OCI Energy. This would strengthen CPS Energy’s position as a pioneer in Texas’s integration of sustainable energy. OCI Energy would be in charge of the project’s conception, funding, building, management, upkeep, and ownership.
“This collaboration reflects our shared commitment to energy innovation and affordability,” stated Sabah Bayatli, President of OCI Energy. “The Alamo City BESS project demonstrates the strength of international partnerships in delivering critical energy infrastructure that will provide CPS Energy customers with greater energy security. We are proud to work alongside CPS Energy and LG Energy Solution Vertech to realize this vision for a stronger, safer grid that provides more affordable power, while supporting local economic development.”
“We are proud to support San Antonio’s energy transition through this strategic collaboration,” stated Jaehong Park, President and CEO of LG Energy Solution Vertech. “This project integrates our advanced lithium-ion batteries with comprehensive solutions—including system integration, control software, and long-term services. The deployment of our BESS marks a key milestone in stabilizing the Texas power grid, and we remain committed to advancing grid reliability as we expand our efforts across Texas.”
“Our community is growing at an exponential rate, and we have been focused on our Vision 2027 strategy to meet this growth,” stated Rudy D. Garza, President & CEO of CPS Energy. “I’m proud of our team for delivering on our commitment to increase energy capacity for our growing community. Every megawatt that we can provide our customers counts.”
Upon execution of the relevant agreements, the project is expected to reach commercial operation in 2027.
