California's Record-Breaking VPP Test: 100,000 Homes Power the Grid
2025-08-10
California's largest electric utilities, in partnership with Tesla and a leading solar installer, conducted a groundbreaking test of virtual power plant (VPP) technology. Over 100,000 homes contributed power from their residential batteries, delivering 535 megawatts to the state grid during peak demand—equivalent to a large hydroelectric dam. This success demonstrates the potential of VPPs to address the challenges of data center growth, heatwave blackouts, and reliance on fossil fuels. While enrollment complexities remain, VPPs are poised for rapid expansion, offering a cost-effective and cleaner energy solution for California and beyond.
