OCI Energy secures $130 million for Alamo City battery project

The project represents a strategic addition to the ERCOT market, boasting a 480-megawatt-hour capacity capable of sustaining 30,000 homes for four hours during peak demand. This discharge capability positions the asset among a small group of long-duration storage systems in Texas, which are increasingly vital for maintaining grid reliability during supply fluctuations.

This financing round follows the project's construction debt closure in 2025 and an official groundbreaking ceremony last month. The transaction is notable as one of Greenprint Capital’s first deals utilizing the technology-neutral Clean Electricity Investment Credit, signaling a shift in how dispatchable energy resources are capitalized. The site is being built with technology from LG Energy Solution Vertech, with Elgin Power Solutions serving as the engineering, procurement, and construction contractor. Once operational, the facility will serve CPS Energy under a long-term capacity agreement.
