California has a quiet grid savior sitting right in people's garages and commercial buildings, and Sacramento is actively trying to break it.
The Demand Side Grid Support (DSGS) program is arguably the most successful virtual power plant initiative in the United States. Run by the California Energy Commission, it brings together thousands of residential and commercial backup batteries—like Tesla Powerwalls—to feed power back into the grid during extreme heatwaves and emergencies. During peak testing, it delivered over 539 megawatts of average output. That is the equivalent of a massive peaker power plant, built out of decentralized consumer hardware.
Yet, state budget battles have threatened its future, pushing proposals to wind it down or shuffle participants into fragmented utility frameworks. That is a mistake. If Sacramento wants to keep lights on and avoid a resurgence of rolling blackouts without relying entirely on dirty fossil fuels, saving the DSGS program isn't optional. It is mandatory.
The Real Value of Virtual Power Plants
Let's look past the political posturing. Building traditional natural gas peaker plants takes years, costs billions, and dirties the air in fence-line communities. Virtual power plants do the exact opposite. They aggregate thousands of small, clean storage systems already installed by homes and businesses.
When wholesale electricity prices spike or grid operators sound emergency alerts, these systems discharge stored solar energy back onto the lines. It happens seamlessly. According to a study by The Brattle Group, keeping the DSGS framework running could yield up to $206 million in net system savings.
Why would anyone kill a program with those metrics? Bureaucratic siloing. State leaders have debated shifting oversight to the California Public Utilities Commission or transitioning participants into legacy utility-run demand response frameworks like the Emergency Load Reduction Program. Clean energy advocates and market experts have pushed back hard, noting that moving these resources risks higher administrative costs, lower enrollment caps, and frustrating delays.
Who Actually Benefits from the Program
Critics often frame home solar and battery subsidies as hand-outs to wealthy homeowners. Data tells a completely different story for this specific initiative.
Research conducted by University of California, Santa Barbara highlighted that DSGS participation is remarkably strong across the Central Valley and the Inland Empire. In fact, participation rates on a per-capita basis skew heavily toward lower-income solar adopters. Communities in the lowest income quintile average over seven DSGS sites per thousand residents.
People aren't just helping the grid; they are getting paid for it. Participants earn performance-based financial incentives that help offset the steep costs of living and electricity in California. Dismantling this program strips away a direct financial lifeline for everyday households trying to cope with high utility bills.
What Needs to Happen Next
Lawmakers must lock in multi-year funding to keep the DSGS program active and stable. Pushing short-term fixes or forcing sudden administrative handoffs creates market uncertainty for aggregators and hardware providers alike.
Sacramento needs to protect what works. Stop tinkering with a framework that is actively keeping the lights on. Extend the funding, secure the rules, and let the state's virtual power plants scale up.
