California’s statewide Demand Side Grid Support (DSGS) distributed storage program is projected to nearly double in capacity by 2028 and could provide up to $206 million in net cost savings to Californians, according to a new report from The Brattle Group and commissioned by Sunrun and Tesla Energy.
The Brattle Group report estimates that from 2025 to 2028, the benefits of DSGS significantly outweigh the costs of the program, providing net system cost savings between $28 million and $206 million. Those savings will benefit all grid-connected customers in California. Participants will also benefit from direct compensation for the power they share with the power system.
As part of its research, The Brattle Group reviewed a recent battery dispatch demonstration event in July that delivered over 500 megawatts to the grid – roughly half the peak electricity demand of San Francisco. “There was a visible reduction in net load, with the average reduction of 539 megawatts representing roughly 1.9% of CAISO’s net peak demand during the event,” the report explained.
