CPS Energy to bolster its clean-energy use with 400 megawatts of battery power

CPS Energy, San Antonio's city-owned utility, has inked a deal for additional 120 megawatts of battery storage capacity, which it hailed as a major step as it transitions to clean energy. Under the deal, OCI Energy will develop a new battery storage project called Alamo City ESS LLC in South Bexar County. The site will allow CPS Energy to power more than 100,000 homes when extreme hot or cold temperatures drive high demand, officials with the utility said.
