Demand Side Grid Support (DSGS)
A virtual power plant program with an indeterminate future set a record in 2025 for the capacity the plant contributed to California's electricity grid.
The 2025 California legislative session ended in disappointment for virtual power plant proponents, as several VPP-related bills were vetoed and funding fell through for an existing program.
Clean energy advocates are urging California lawmakers to restore funding to a fast-growing distributed energy program that has shown its ability to support the grid during a test run.
An aggregation of more than 100,000 residential batteries provided an average 535 MW of support to California’s electricity grid during a test to prepare for the hot summer period ahead.
As the growth in battery capacity is accelerating, the new milestone is one-quarter of the way to the state’s projected need of 52 GW of battery storage capacity by 2045.
