San Antonio, Wednesday, 20 May 2026.
OCI Holdings has initiated a 480-megawatt-hour battery facility in Texas. Launching in 2027, this strategic investment stabilizes grid volatility while capturing up to 40% in US tax incentives.

Fortifying the Texas Grid

On May 19, 2026, OCI Energy, the U.S. renewable energy subsidiary of South Korean firm OCI Holdings, hosted a groundbreaking ceremony for the Alamo City Energy Storage System (ESS) in Bexar County, Texas [1][3][4]. Spanning approximately 140,000 square meters [1][4][5], the utility-scale facility is designed with a power output of 120 megawatts (MW) and a total storage capacity of 480 megawatt-hours (MWh) [1][2][3]. This development marks a concerted effort by OCI Holdings to expand its direct operation of energy storage assets to secure long-term revenue streams, shifting away from a historical model of selling projects immediately upon completion [1][4][5].

Strategic Partnerships and Financial Incentives

To guarantee the project’s long-term commercial viability, OCI Energy has signed a 20-year storage capacity agreement with local utility provider CPS Energy [1][3][4]. While OCI Energy developed, financed, and will retain ownership of the Alamo City facility, CPS Energy will be responsible for its day-to-day operation [2]. CPS Energy, the largest regional energy company in the United States, supplies electricity and natural gas to roughly 1.28 million households in Texas and has maintained a collaborative partnership with OCI Holdings since 2012 [4][5][6]. Rudy D. Garza, the chief executive of CPS Energy, noted that such energy storage projects provide the flexibility required to integrate diverse energy resources and ensure reliable power for the community during critical periods [3].

Broader Corporate Strategy and Market Impact

The Texas facility is just one component of OCI Energy’s aggressive expansion across the North American renewable sector. The subsidiary currently manages a robust pipeline of 31 projects centered in Texas, representing a combined capacity of 7 gigawatts (GW)—comprising 3.9 GW of solar power and 3.1 GW of energy storage systems [4][5]. In a complementary move to optimize its portfolio, OCI Energy recently accelerated the securitization of its renewable assets, selling a 50 percent stake in the 500 MW Ra-Saye project to Israeli energy firm Arava Power on May 14, 2026, with plans to co-develop and operate that facility ahead of its targeted 2028 commercial launch [4].
