- Sunrun (RUN, Financial) dispatched over 340 megawatts of power on June 24, 2025, across multiple states during a heat wave.
- The company operates nearly a gigawatt of total battery capacity, equivalent to a nuclear power plant's peak power.
- Sunrun activated more than 5,600 batteries in Puerto Rico within an hour to assist during power shortages.
Sunrun Inc. (RUN) successfully dispatched more than 340 megawatts of peak power on the evening of June 24, 2025, to support the power grids in states including California, New York, Massachusetts, Rhode Island, and Puerto Rico. The dispatch came as a response to an urgent need for energy during a severe heat wave affecting the East Coast, which has overstressed the traditional power infrastructure.
With its position as the world's largest distributed battery power plant operator, Sunrun boasts nearly a gigawatt of total battery capacity. During the critical evening hours in California, Sunrun's battery fleet dispatched 325 megawatts of power from 7 p.m. to 9 p.m., managing to ease the demand peak when solar generation dips.
In Puerto Rico, Sunrun demonstrated rapid deployment capabilities by activating over 5,600 batteries in less than an hour. This swift response helped stabilize the island's power supply during generation shortfalls caused by the soaring temperatures.
Sunrun's subscription-based model enhances its ability to quickly deploy and manage decentralized battery systems. This allows Sunrun to act effectively as a virtual power plant, providing a strategic advantage in responding to grid challenges posed by extreme weather conditions.
Mary Powell, CEO of Sunrun, stated, "Home storage paired with solar is a reliable and controllable resource that can provide on-demand power to the grid to prevent blackouts and reduce energy prices for all households. We must fully embrace these technologies if we're to achieve energy security for America."
Sunrun continues to prove its grid-scale impact, establishing itself as a critical infrastructure provider capable of rapid power deployment, surpassing the timelines required for traditional power plants. With grid congestion and extreme weather events on the rise, Sunrun's innovations in distributed power plant solutions are poised to play a critical role in the future of energy resilience and sustainability.
