OCI Energy Secures Construction Financing From ING for 120 MW Alamo City Battery Storage Project

Why It Matters

Large‑scale storage like Alamo City enhances grid reliability and reduces reliance on costly peaker plants, a vital step as Texas faces rising demand and more renewable integration. The project also showcases a successful public‑private partnership model for future energy infrastructure.

Key Takeaways

• 120 MW/480 MWh BESS powers 30,000 homes for four hours
• OCI Energy finances; CPS Energy will operate the system
• LG Energy Solution provides battery cells; ING funds construction
• Project enhances grid reliability during Texas peak‑load events
• Commercial operation slated for 2027, expanding Texas storage capacity

Pulse Analysis

The Alamo City Battery Energy Storage System marks a significant step in Texas’ transition toward a more flexible grid. With a 120‑megawatt power rating and 480 megawatt‑hours of stored energy, the facility can shift surplus generation from off‑peak periods to the evening surge that typically strains the San Antonio network. By delivering up to four hours of power for roughly 30,000 homes, the BESS mitigates peak‑load stress, curtails the need for expensive peaker plants, and bolsters resilience against heat‑driven demand spikes that have become routine in the Lone Star State.

OCI Energy is shouldering development and long‑term financing, while CPS Energy will own the dispatch schedule under a storage agreement. Construction funding comes from ING, and the battery modules are supplied by LG Energy Solution Vertech, a leader in lithium‑ion technology. Elgin Power Solutions handles engineering, procurement, and construction, ensuring the project meets the accelerated timeline that targets commercial operation in 2027. The collaboration blends global capital, cutting‑edge chemistry, and local utility expertise to create a reliable, grid‑scale asset that aligns with Texas’ renewable integration goals.

The Alamo City BESS joins a wave of large‑scale storage projects across the United States, from Enbridge’s $1.2 billion Cowboy venture in Wyoming to California’s expanding battery farms. As utilities confront rising electricity demand and stricter reliability standards, such installations become essential for balancing intermittent solar and wind output. Analysts expect storage capacity in the U.S. to exceed 30 gigawatts by 2030, and projects like this provide a template for public‑private partnerships that can accelerate that growth while delivering tangible benefits to ratepayers.

Deal Summary

OCI Energy’s 120 MW Alamo City Battery Energy Storage System in Bexar County, Texas, has broken ground, with ING providing construction financing. The project, owned by OCI Energy and operated by CPS Energy, will deliver 480 MWh of storage capacity to support the San Antonio grid, with LG Energy Solution Vertech supplying battery technology and Elgin Power Solutions as EPC contractor.
