California drops funding for its biggest VPP

California has cut off funding for its biggest virtual power plant. State budget language finalized last week carries no new money for the Demand Side Grid Support program, according to Canary Media, and the Newsom administration has blocked an effort to keep it funded through next year. Described by Canary Media as one of the biggest virtual power plants in the country, the program is the state's most successful demand-side grid resource — and now has no revenue path from Sacramento.

The absence of new authorization does not shut the program down tomorrow; it means Sacramento is no longer paying for the load reductions that make it a resource at all. Without that payment stream, the participating customers and aggregators have little reason to stand by for grid emergencies.

The budget decision is a policy-capital event, and virtual power plants are the cheapest form of peak capacity a grid can buy — California just told its largest such resource that success in shifting demand isn't enough to justify continued funding. Success did not buy durability.

As this publication has argued, the buildout is gated by consent before capital, and this is consent withdrawn by the state budget rather than by ratepayers. The likely consequence is that aggregators and their customers who expected state payments will see that revenue path close, and grid operators will lose a tool for peak shaving that renewable-heavy grids depend on.

The decision draws a line between infrastructure and programs: a transmission line or a battery is capital spending, protected by rate base and long-term cost recovery, while a virtual power plant is a budget line, subject to the politics of the year. The market will price that distinction.

Virtual power plants in California are discretionary spending, not infrastructure. Capital flows to revenue certainty, so the next dollar of demand-side investment is more likely to land in markets with explicit capacity payments or behind-the-meter economics than in a program that lives or dies on the governor's next budget — a cost the state will pay at the peak of the next heat wave.
