Sunrun Inc. (NASDAQ:RUN) and Tesla, Inc. (NASDAQ:TSLA) supplied a record 745 megawatts of electricity to California's power grid on October 6 using networked home batteries. The dispatch surpassed the prior record of 669 megawatts set just one day earlier and significantly topped a previous peak of 580 megawatts reached in September. Over 120,000 residential battery systems operated by Sunrun are currently enrolled to help support the state's electric grid.

The record output occurred during evening peak demand periods of a heat wave, when day-ahead power prices surpassed $200 per megawatt-hour. The performance highlights the growing operational impact of virtual power plants, which aggregate individual home battery systems to reinforce grid stability during high demand. Sunrun projects that its distributed power plant operations will generate roughly $40 million in GAAP revenue and over $10 million in operating margin for 2026.

Looking ahead, Sunrun plans to expand its grid initiatives alongside Tesla and Everyday Electric by enrolling nearly 21,000 additional devices in a Google-funded virtual power plant with PG&E, scheduled to begin dispatching this month. Investors are also monitoring company financials after Sunrun lowered its 2026 cash generation forecast to between $200 million and $375 million in August. Sunrun is scheduled to report its third-quarter earnings on November 4.
