These capabilities give Sunrun a dispatchable capacity of 650 MW of peak power—enough to supply 480,000 homes—making it a critical player in preventing blackouts and stabilizing the grid during peak demand events.
“Not only is Sunrun providing Americans with reliable and affordable energy, we are scaling our generation business and helping stabilize the electricity grid while we do it,” said Mary Powell, CEO of Sunrun.
Sunrun’s distributed power plants have supported grids in California, New York, Massachusetts, and Puerto Rico this summer, including a single-day dispatch of over 340 MW during a prolonged June heatwave. In Puerto Rico, more than 37,000 home batteries have been activated to help the island avoid evening blackouts.
With more than 3.2 GWh of networked storage capacity installed across 195,000 solar-plus-storage systems, Sunrun’s residential network rivals the scale of mid-sized utility plants, but with faster deployment timelines and local resilience benefits.
By combining grid service contracts, advanced battery management, and mass-market solar deployment, Sunrun is positioning residential customers as an integrated part of America’s clean energy infrastructure.
