Sunrun Inc. said in a press release on June 24, 2026, that its deal with Renew Home and Tesla Inc. will aggregate home batteries, smart thermostats, and vehicle-to-grid systems into a virtual power plant. The companies say this network can supply flexible capacity to hyperscale data centers and utilities.
Framework and Capacity
The press release states the companies offer 16.8 gigawatts of flexible capacity across the nation’s largest data-center markets. This resource draws dispatchable power from hundreds of thousands of home battery systems operated by Sunrun and Tesla, plus flexible peak capacity from more than 8 million smart thermostats and devices managed by Renew Home.
Sunrun and its partners describe the combined assets as the largest distributed power plant in the U.S., capable of injecting net new electrons from home batteries paired with rooftop solar and shifting household load during peak hours. They call the offering capacity-as-a-solution, emphasizing that it can be deployed in months rather than years to free transmission headroom, ease congestion on distribution networks, and extend the duration and depth of available capacity. Offtakers require no additional hardware, software, interconnection, water, or land. The resource can support peak shaving, local grid assistance, and fast-response ancillary services.
Markets, Deployment, and Partner Roles
The framework targets hyperscalers and utilities facing surging electricity demand from data centers and AI growth, while aiming to lower household energy costs and reward participating customers. Capacity is allocated on a first-come, first-served basis, offering a turnkey solution for large technology customers and utilities. One account described the combined fleet as providing enough capacity to support the demands of 17 major data centers during peak times.
In the PJM Interconnection region, the partners report more than 300 megawatts ready for immediate use in Virginia, with plans to reach at least 500 megawatts in the state by 2030. They have pledged capacity into PJM’s proposed Reliability Backstop Process, which could prompt PJM to immediately release over a gigawatt of capacity. The companies plan to expand the program nationwide by 2030.
Sunrun positions itself as America’s largest provider of home battery storage, rooftop solar, and home-to-grid power plants, offering customers a no-upfront-cost subscription model. Tesla contributes residential battery systems and electric vehicle-related grid resources, while Renew Home manages smart thermostats and devices.
By packaging distributed household assets into an offtake-ready resource, the partners argue the framework offers hyperscalers and utilities a faster route than building new generation or waiting out long interconnection lead times. The speed at which this capacity becomes market-recognized will depend on commercial uptake and regulatory outcomes such as the PJM review.
