Your thermostat, EV charger, or home battery could be earning you money. That’s the pitch behind virtual power plants, or VPPs—programs where utilities pay households for the right to dial back their electricity use during peak demand. The numbers are real: Seth Frader-Thompson, CEO of EnergyHub, says smart thermostat programs typically offer a $50 to $150 signup bonus plus $25 to $50 annually, while home battery and EV programs can yield hundreds or even thousands of dollars per year. More than 500 VPP programs already operate in the US, with roughly 4 million smart-thermostat households enrolled as of last year.
The mechanics are less dramatic than the name suggests. In most cases, the utility isn’t pulling power from your battery back into the grid—it’s simply throttling your consumption. Your thermostat might get adjusted a few degrees during a heat wave, or your EV charging might slow down for an hour. Frader-Thompson puts the scale in perspective: one home’s reduction is trivial, but ‘when you put it together at the scale of hundreds of thousands, or millions, it has a pretty profound impact,’ equivalent to firing up an entire power plant.
Not everyone is convinced the programs are ready for prime time. Severin Borenstein, faculty director of UC Berkeley’s Energy Institute at Haas, warns that poorly implemented VPPs could end up paying customers for energy they weren’t going to use anyway—costs that get passed on to non-participants. Still, he sees genuine potential: done right, VPPs could help utilities avoid expensive grid upgrades or emergency conservation measures. The industry is also pushing toward true bidirectional power, where your EV or home battery actually sends electricity back to the grid, though most consumer programs haven’t reached that point yet.
Signing up is often buried in unexpected places. Your utility’s website may not even use the term ‘virtual power plant’—you might need to search for ‘demand response,’ ‘peak rewards,’ or ‘managed charging’ instead. Frader-Thompson notes that most people actually discover these programs through their device manufacturer, whether that’s a smart thermostat app, an EV automaker, or a battery company. Eligibility is annoyingly specific too: your exact device model, utility territory, and rate plan all matter. Programs cluster in California, Texas, New England, and parts of the mid-Atlantic, where grids are stressed and policies are supportive. The Google-sized twist here is that tech giants are now investing in VPPs to help power their data centers, which could accelerate adoption far beyond what utility marketing alone would achieve—though whether that expansion comes with better consumer terms or just more aggressive enrollment targets remains an open question.
