California's Battery Storage Surges, Saving Millions and Powering Grid
California's battery storage capacity has surged, with the Demand Side Grid Support (DSGS) program enrolling 700 MW of battery capacity, equivalent to a large public storage facility. This capacity is projected to double by 2028. Meanwhile, residential batteries are expected to reach nearly 4 GW by the mid-2020s, matching multiple storage units near me in power. Globally, China is considering a nearly 1 TWh vehicle-to-grid network.
California's advancements are notable. On July 29, 2025, the state conducted the world's largest virtual power plant test, with over 100,000 distributed batteries providing 539 MW for two hours. This test demonstrated the potential of battery storage to support the grid. On June 27, 2024, residential batteries provided nearly 70% of enrolled capacity during a peak grid emergency, showcasing their reliability.
The DSGS program is expected to produce net savings of up to $206 million between 2025 and 2028 by replacing expensive gas peaker plants. This highlights the economic benefits of battery storage. Globally, tapping U.S. passenger vehicles could provide about 30 TWh of mobile storage, nearly three days of backup power, indicating vast untapped potential.
California's battery storage capacity continues to grow, with significant projects like the DSGS program and residential battery installations. These advancements, along with global initiatives like China's vehicle-to-grid network, demonstrate the increasing role of battery storage in supporting grids worldwide. The economic and reliability benefits of these storage units near me are becoming increasingly clear.
