Nearly half of all residential storage capacity installed in the U.S. last year came from one company: Sunrun. SEIA's inaugural U.S. Energy Storage Market Outlook report shows the sector added 3.1 GWh in 2025. Sunrun's reported 1.5 GWh represents approximately 48% of that total. “Our deliberate and decisive pivot to provide Americans with energy independence is why Sunrun leads the residential energy storage sector.” — Sunrun CEO Mary Powell.

A new report shows that Sunrun’s first-of-its-kind distributed power plant with PG&E successfully supplied targeted power to neighborhoods with highly-constrained electric grids When power lines and substations are nearing capacity, utilities have to add more distribution infrastructure. This collaboration shows that home batteries can come to the rescue by dispatching critical energy exactly when and where it’s needed. More than 1,000 Sunrun customers’ storage-plus-solar systems exported energy over last summer and fall to alleviate overloaded substations and power lines, with the goal of helping PG&E avoid or defer distribution upgrades while generating net savings for all utility customers. “Working with partners like Sunrun is a win for our customers, our electric grid and California as a whole. This program shows how customers can help improve local grid reliability as we support the state’s growing need for energy,” said Patti Poppe, CEO of PG&E Corporation. Read more: bit.ly/40rkjuK

Winter Storm Fern left hundreds of thousands of homes without power after impacting many parts of the country with ice and freezing temperatures, causing energy generation and distribution to go offline. CEO Mary Powell joined @LizClaman to discuss how Sunrun’s products and services are designed to meet moments like these, providing homeowners with energy independence, reliability, and security, all while sending critical energy back to the grid. “We are bringing independence to Americans [and] we are helping to build a grid that can be more energy independent,” Mary said. “There is nothing more reliable than the kind of distributed power plant that we’re building.”

Brattle experts assessed #VPP performance during an event called by Sunrun, Tesla, and other aggregators in California earlier this week, finding that residential batteries provided over 500 MW of capacity to the California power system during the event. bit.ly/3JfAqpS
