Sunrun’s Distributed Power Plant Sets U.S. Record After Fivefold Growth in Customer Participation
Rapid Expansion Transforms Sunrun Into a Major Energy Player
Sunrun, already America’s leading provider of home battery storage and solar, has just made history—turning its distributed power plant network into the nation’s largest after quintupling customer participation in 2025. The company dispatched nearly 18 gigawatt-hours of energy from home batteries to grids across the country, helping to power 15 million homes for an hour and providing a peak output of 416 megawatts, rivaling many fossil-fuel peaker plants.
Customer Participation Surges Past 100,000, Unlocking Grid Resilience Benefits
Participation in Sunrun’s programs soared from about 20,000 customers in 2024 to more than 106,000 in 2025. More than 1,300 successful dispatches supported local grids during periods of extreme demand or risk, with at least one program dispatching every day through the year.
| Metric | 2024 | 2025 |
|---|---|---|
| Customer Participation | 20,000 | 106,000 |
| Dispatches | - | 1,300+ |
| Energy Dispatched (GWh) | - | 18 |
| Peak Capacity (MW) | - | 416 |
Flexibility and Reliability: Sunrun Outpaces Conventional Power Plants
This massive jump in scale arrived just as U.S. power grids were facing surging demand. From heatwaves in Texas—where Sunrun partnered with TXU Energy and executed over 200 dispatches through extreme weather—to California, where Sunrun’s network could power over half of San Francisco during peak usage, these distributed solutions are increasingly critical. On the East Coast, in Maryland, Sunrun helped pioneer vehicle-to-grid technology, showing that EV batteries can help keep the lights on. In Puerto Rico, more than 30,000 local customers repeatedly avoided blackouts when traditional plants failed.
Direct Customer Impact: Over $17 Million Earned in 2025
Beyond the resilience benefits, Sunrun customers are being compensated for supplying power when it’s needed most. Utilities pay Sunrun for grid support, and those payments—over $17 million in total last year—get shared with participating households. That means more homeowners now have an incentive to help strengthen the nation’s grid while controlling their energy bills.
Scaling Toward the Future: 10 Gigawatt-Hours Targeted by 2028
As power demand accelerates—driven by datacenters, AI, electrification, and extreme weather—Sunrun aims to expand its dispatchable battery capacity to 10 gigawatt-hours by 2028. With 217,000 home batteries already deployed, Sunrun is positioned to play an ever-larger role in shaping how America responds to the energy challenges ahead.
| Key Regions | Program Highlights |
|---|---|
| Texas | 200+ dispatches with TXU Energy during heatwaves; new partnerships with NRG Energy and Tesla Electric |
| California | Largest U.S. distributed power plant; supplied half of San Francisco during peak |
| Maryland | First EV vehicle-to-grid project with Ford & Baltimore G&E |
| Puerto Rico | 30,000+ homes stayed powered up during outages |
| Northeast | Largest plant in New York; support across MA and RI during heatwaves |
Looking Ahead: Sunrun’s Role as a Grid Solutions Leader
The U.S. electricity system is at a crossroads, with demand set to rise 25% by 2030 according to forecasts. Sunrun’s rapid scale-up demonstrates not just technology leadership, but a model for community-driven energy resilience—and puts the company at the center of the nation’s efforts to keep up with accelerating power needs.
Investors and consumers alike may want to keep an eye on further grid partnership announcements and state-level policy changes, as Sunrun’s network could become a core pillar for the next wave of American energy innovation.
