“Sunrun’s groundbreaking program with PG&E reveals that distributed energy crops may also help communities keep away from the excessive price of including extra poles and wires to accommodate load growth,” stated Sunrun CEO Mary Powell. “We noticed time and time once more that our clients’ batteries delivered location-specific load reduction with excessive precision and constant efficiency.”
Sunrun’s Native PeakShift Energy distributed energy plant is a part of PG&E’s Seasonal Aggregation of Versatile Vitality (SAVE) program. The distributed energy plant reportedly dispatched greater than 50 occasions from July by October 2025, when native demand neared system capability, totaling greater than 1,200 dispatching hours. Sunrun clients with photo voltaic and programs who’re close to constrained energy traces and substations in PG&E’s service space have been enrolled in this system.
“With the ability to present power to my native neighborhood simply makes a whole lot of sense,” stated Sunrun buyer Tom Weldon, whose San Jose residence sits close to a constrained energy line. “When warmth waves arrive, we all know that our batteries are going to assist out when the grid is careworn. It’s one thing I really feel actually good about.”
A post-season program analysis report by Demand Facet Analytics discovered that Sunrun’s battery groupings carefully adopted PG&E’s dispatching directions and stored electrical masses beneath the working limits at the entire energy traces and substations. Every location obtained totally different directions based mostly on machine studying, forecasted climate and each day distribution system load forecasts.
PG&E expanded Sunrun’s program from 600 clients to greater than 1,000 throughout the enrollment interval. Sunrun clients enrolled in Native PeakShift Energy obtained $150 per battery for sharing their saved photo voltaic power with their communities, whereas Sunrun was compensated for coordinating the battery dispatches. Sunrun has greater than 217,000 residential battery programs throughout the nation.
