Sunrun’s grid services business is exploding as more homeowners pair batteries with rooftop solar. (PV Magazine)
VPP participation jumped 400% annually, with 106K+ homes now enrolled in Sunrun’s VPP programs nationwide.
Battery attachment rates hit 70% among new customers in Q3, up 60% in the last year, pushing Sunrun’s aggregated storage fleet to 3.7 GWh across 17 programs.
Between the lines: By linking tens of thousands of home batteries, Sunrun is building a distributed VPP capable of supporting utilities during demand peaks—an increasingly valuable grid resource as data centers drive load growth.
