California’s largest electricity provider, PG&E, has been a major driver for California’s leading position among US states as an energy storage market. Along with other IOUs, Southern California Edison (SoCal Edison) and San Diego Gas & Electric (SDG&E), the utility’s adoption of battery energy storage system (BESS) technology has been instrumental in California’s overall position among the US states. Over the past five years since deployment began at scale, PG &E has brought online more than 2,300MW of energy storage resources and plans to add more than a gigawatt to that over the next year and a half to the end of 2025. The utility is saving millions of dollars by deploying large-scale BESS to solve capacity and voltage issues, saving millions compared to a traditional poles and wires upgrade. Nearly all of these resources are third-party-owned.
