CPS Energy, a utility in the United States that provides electricity and natural gas, has signed two storage capacity agreements (SCAs) with Eolian LP for the storage capacity of 350 megawatts (MW) of battery energy storage.
The agreements include two projects, “Ferdinand” and “Padua 2,” with storage capacities of 200 MW and 150 MW, respectively.
This agreement, along with a previous agreement for 50 MW of storage signed in 2023, brings CPS Energy’s total battery storage capacity under contract to 400 MW.

Located in South Bexar County, Texas, these projects are expected to be operational by mid-2026.
Aaron Zubaty, CEO of Eolian said, “Following on to the 50 MW Padua 1 project already under construction for CPS Energy, this additional 350 MW of  four-hour duration battery energy storage will provide new dispatchable capacity to the San Antonio area by mid-2026, representing the single largest buildout of standalone battery energy storage in ERCOT to date and proving that deployment of fast and flexible energy storage resources at critical grid locations can bridge the many years until new transmission can be constructed to further support load growth and alleviate systemwide congestion,”

The projects aim to meet the energy needs of the San Antonio community for 20 years.
Once operational, they will contribute at least $175,000 each year for five years to CPS Energy-sponsored activities and scholarships within the Greater San Antonio area.
