Tesla, residential clean energy provider Sunrun, and Google-backed home energy management company Renew Home have announced a partnership to aggregate millions of home energy devices into the largest distributed power plant in the United States, capable of delivering more than 16GW of flexible energy capacity to hyperscalers and utilities.

As reported by ESG Today, the initiative combines hundreds of thousands of home battery systems operated by Tesla and Sunrun with more than eight million smart thermostats and connected devices managed by Renew Home. The platform will deliver power to the grid from home batteries paired with solar generation while simultaneously shifting household load during peak demand hours, spanning multiple states without requiring additional hardware, software, interconnection, water, or land usage.

Mary Powell, CEO of Sunrun, said: "When data centers are asked to throttle down operations during the most expensive and stressful hours of the day, we can activate our distributed power plants to help provide them the power they need while also protecting American families from footing the bill for costly new infrastructure."

Colby Hastings, Senior Director of Residential Energy at Tesla, said: "America's grid faces mounting pressure from data centers, electrification, and manufacturing growth that no single infrastructure solution can solve fast enough. A huge piece of the answer is already in place — in the batteries, thermostats, and electric vehicles inside millions of American homes, waiting to be put to work."

More than 300MW of capacity is available for immediate deployment in Virginia, with a target of at least 500MW in that state by 2030. The companies said they are capable of deploying multiple gigawatts of additional capacity nationally and encouraged hyperscalers to engage early, as available capacity will be allocated on a first-come, first-served basis.

The companies have also committed capacity to PJM's proposed Reliability Backstop Process, which could immediately unlock more than 1GW, with further capacity deployable for peak shaving, locational grid relief, and ancillary services. The capacity-as-a-solution framework can be deployed in months by creating additional headroom on the existing electricity grid, freeing up transmission capacity and easing congestion on distribution infrastructure.

Residential participants will benefit through lower electricity bills, rewards, and maintained power during outages, aligning household financial incentives with grid resilience outcomes.
