Fun fact: Across all 10 major @Tesla Virtual Power Plant events in California in 2026, Powerwall owners have now collectively sent 5 GWh of electricity from their home batteries back to the grid during periods of peak demand. That's enough energy to power ~1.2 million U.S. homes for 3 hours. For those who don't know what a virtual power plant is, it's basically a network of distributed energy sources such as homes with solar and battery systems, working together as a single power plant. The combined energy of these sources is used to support the electrical grid. Participants can give the VPP program permission to use their energy (battery) as a resource during high demand events and then they get paid for the energy they sent back to the grid (such as $2/kWh in California).
