OCI Holdings, the green energy and chemical conglomerate best known for producing polysilicon for solar panels, is expanding its footprint in the North American power grid.
The company said Wednesday that its Houston-based subsidiary, OCI Energy, has broken ground on a major utility-scale battery storage project in Bexar County, Texas, amid a broader corporate push into the North American renewable energy market.
The project, dubbed Alamo City, is being developed in partnership with San Antonio’s municipal utility, CPS Energy. Spanning a 140,000-square-meter site, the facility will boast an output capacity of 120 megawatts and a storage capacity of 480 megawatt-hours, making it one of the more significant grid-balancing installations in the region.
Scheduled to begin commercial operations in 2027, the installation is engineered to discharge up to four hours of continuous backup electricity during peak demand periods — enough to supply roughly 30,000 households in the San Antonio metropolitan area.
