Tesla and Sunrun’s virtual power plant dispatch record 580 MW to California grid

Sunrun and Tesla pulled a record 580 megawatts of power from home batteries onto California’s grid during a heat wave on September 9, the largest residential distributed power plant event ever recorded.

The dispatch pooled more than 140,000 home batteries across the state and ran for a three-hour window in the evening, when the grid was straining under air-conditioning load.
