Sunrun Inc. (RUN) announced back-to-back record energy dispatches from residential batteries to support California's electrical grid during a severe heat wave. Working alongside Tesla, home battery storage systems supplied 669 megawatts of peak power on October 5 and reached a new record of 745 megawatts on October 6. Triggered when wholesale electricity prices exceeded $200 per megawatt-hour, the combined dispatches provided enough electricity to power all households in San Francisco and San Jose during peak evening hours.

The record-setting events highlight how distributed residential clean energy systems can function as large-scale power plants to stabilize electrical infrastructure. By tapping into home batteries during periods of extreme strain, utility operators can reduce pressure on real-time power prices and lower blackout risks without relying solely on building costly new power plants. Sunrun currently has over 120,000 home batteries enrolled in grid support programs across California.

Looking ahead, residential battery capacity continues to grow rapidly, exceeding prior dispatch records of 539 megawatts in July 2025 and 580 megawatts in September 2026. Sunrun, Tesla, and Everyday Electric also plan to launch a Google-funded distributed power plant project with Pacific Gas and Electric in the San Jose region, targeting initial dispatches later this month.
