Sunrun Dispatches a Record Amount of Energy to California’s Grid During a Historic Event
Sunrun (NASDAQ:RUN), California's largest distributed power plant operator, achieved a record-breaking energy dispatch of 360 megawatts to the state's grid during a scheduled test event. The analysis by The Brattle Group confirmed that Sunrun's fleet of home batteries contributed over two-thirds of the total 535 megawatts delivered during the July 29 event between 7-9 PM.
This marks Sunrun's second significant grid contribution this summer, following a 325-megawatt dispatch on June 24. The company's network of over 100,000 residential batteries demonstrated consistent performance, effectively reducing peak demand. Participating customers can earn up to $150 per battery per dispatching season, while Sunrun receives compensation for managing the dispatches.

Insights
Sunrun demonstrates market leadership in virtual power plants, delivering 360MW to California's grid, validating its distributed energy revenue model.
Sunrun has achieved a significant operational milestone by contributing 360 megawatts (over two-thirds of the total 535MW) during a coordinated battery discharge event in California. This two-hour test on July 29 effectively created a virtual power plant equivalent to powering half of San Francisco, according to The Brattle Group's analysis.
What makes this achievement particularly noteworthy is the reliability demonstrated by Sunrun's network of distributed home batteries. The Brattle Group confirmed consistent performance without fluctuations or attrition—essentially proving these residential systems can function with the dependability of traditional power plants.
This marks Sunrun's second major dispatch this summer, following a 325MW contribution on June 24, establishing a pattern of reliable service. The successful test validates Sunrun's grid services business model, where both the company and participating customers receive compensation (customers earning up to $150 per battery per season).
The dispatch occurred during evening hours (7-9pm), precisely when grid demand peaks and electricity generation typically becomes most valuable. By reliably serving this critical "net peak" period, Sunrun is positioning its distributed energy resources as a legitimate alternative to building new centralized generation capacity.
This demonstration proves Sunrun has successfully scaled its virtual power plant capabilities to utility-grade performance levels, creating a new revenue stream beyond equipment sales while addressing California's growing grid stability challenges.
A new analysis confirms Sunrun’s leading position as the largest operator in California’s statewide distributed power plant, delivering 360 megawatts to the state’s grid on a record-setting night
SAN FRANCISCO, Aug. 04, 2025 (GLOBE NEWSWIRE) -- A new analysis by The Brattle Group found that Sunrun’s (Nasdaq: RUN) fleet of home batteries across California was the largest contributor to a historic distributed power plant dispatch event that delivered an average of 535 megawatts to the grid—enough to power more than half of the city of San Francisco.
Multiple distributed power plant aggregators, of which Sunrun is the largest, discharged home batteries in coordination with the California Energy Commission, the California Independent System Operator, and local utilities during a scheduled test event between 7 and 9 p.m. on Tuesday, July 29. The goal of the event was to prepare for anticipated need-based dispatches during heat waves in August and September.
The Brattle Group found that the output from more than 100,000 residential batteries resulted in “a visible reduction in net load” across the statewide grid when output typically is most valuable to the system.
“Performance was consistent across the event, without major fluctuations or any attrition,” said Ryan Hledik, Principal at The Brattle Group. “Events like these demonstrate to system operators that residential batteries provide dependable, planning-grade performance at scale.”
“Residential batteries—and other sources of distributed flexibility—can serve CAISO’s net peak, reduce the need to invest in new generation capacity, and relieve strain on the system associated with the evening load ramp,” Hledik said.
Sunrun’s home batteries supplied more than two-thirds of the total energy dispatched during the event—averaging more than 360 megawatts over the two hours—and have the capability to deliver this critical energy every day. Sunrun’s batteries acted in the same way as a traditional power plant and decisively knocked down the state’s evening peak demand for electricity.
“This customer-led solution is a win-win for households and the grid,” said Sunrun CEO Mary Powell. “Distributed home batteries are a powerful and flexible resource that reliably delivers power to the grid at a moment's notice, benefiting all households by preventing blackouts, alleviating peak demand, and reducing extreme price spikes."
This is the second time this summer that Sunrun’s fleet of home batteries helped reduce California’s peak energy demand. On June 24, Sunrun’s statewide distributed power plant dispatched 325 megawatts of peak power from 7 to 9 p.m. Participating Sunrun customers are compensated up to
