Battery Energy Storage System (BESS) |
The Alamo City BESS project in Texas marks a major milestone in energy storage and US-Korea clean energy collaboration.
Texas Battery Storage Capacity to Expand with 120MW BESS
OCI Energy, CPS Energy, and LG Energy Solution Vertech will jointly develop the Alamo City Battery Energy Storage System (BESS). The 120MW/480MWh facility, located in Bexar County, Texas, will supply backup power during peak demand periods.
Under the deal, LGES Vertech will deliver the BESS units and energy management systems to OCI Energy, the project developer. CPS Energy, the municipal utility serving San Antonio, will purchase the storage capacity through a long-term offtake agreement.
This collaboration increases CPS Energy's battery storage portfolio to 520MW, ensuring greater grid reliability across south-central Texas.
BESS Project Aligns with Vision 2027 Energy Plan
The Alamo City BESS project is scheduled to begin operation by late 2026. It will play a crucial role in Vision 2027, CPS Energy’s roadmap to a balanced, reliable, and sustainable energy mix.
Vision 2027 includes plans for 1,710MW of natural gas, 500MW of firming capacity, 84MW of wind, and 730MW of solar. The addition of this battery storage system helps CPS diversify and decarbonize its energy infrastructure.
As a result, this project strengthens both energy resilience and cross-border cooperation between the US and South Korea in the energy transition.
The Metalnomist Commentary
The Alamo City BESS is more than a storage project—it’s a blueprint for municipal utilities navigating the clean energy transition. With players like OCI, CPS, and LGES joining forces, we’re seeing the integration of international technology with local grid needs. Expect similar regional collaborations to follow as US battery storage demand accelerates through 2030.
