Tesla, Sunrun, and Renew Home announced a 16 GW virtual power plant initiative to supply distributed renewable energy capacity to data centers.
Three of the largest U.S. residential VPP providers—Sunrun, Renew Home, and Tesla—have announced an agreement to deliver a combined 16 gigawatts of flexible capacity to hyperscalers and utilities. The three companies are developing distributed VPPs in regions where new data centers may strain grid capacity.
The partners' framework, called "capacity-as-a-solution," allows data centers to pay for VPP capacity from nearby distributed energy resources. When the grid experiences stress, utilities can activate these resources rather than requiring the data center to curtail its operations. "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," Sunrun CEO Mary Powell said in the announcement.
This builds on momentum that began last September, when VPP provider Voltus partnered with data center developer Cloverleaf Infrastructure to establish a "bring your own capacity" framework. Under this model, data centers finance the flexibility potential of surrounding communities while Voltus sells that distributed capacity to hyperscalers seeking local grid capacity demonstrations. In May, Voltus announced its first major deal under this framework: a 100-MW VPP contract with Google. The Sunrun, Renew Home, and Tesla effort represents a significant scaling of this concept to 16 GW.
The three companies plan to aggregate capacity from demand-side and energy-exporting devices—including home battery systems operated by Sunrun and Tesla, as well as smart thermostats operated by Renew Home—creating what they characterize as the largest distributed power plant in the country, though spanning multiple utilities and service territories. Capacity will be allocated on a "first-come, first-served" basis, with no customers yet announced.
Ben Brown, Renew Home CEO, told Latitude Media that "a substantial portion" of the 16 GW is already operational and dispatchable, with additional capacity coming online over the next six to twelve months. The framework combines existing distributed energy resources "with a long-term strategy to accelerate deployment of new flexible capacity across participating platforms."
According to the companies' VPP capacity explorer, available capacity includes 4.7 GW in California, 1.7 GW in Texas, 684 MW in Illinois, and 219 MW in Ohio. In Virginia, they have more than 300 MW readily available, expected to reach 500 MW by 2030. Virginia, home to one of the world's highest concentrations of data centers, has been actively encouraging grid utilization through regulatory measures. Earlier this year, the state signed into law a bill directing state energy regulators and utilities Dominion Energy and Appalachian Power to develop methods for quantifying and reducing grid waste, including through distributed energy resources.
The three companies have also committed to providing capacity to PJM's proposed Reliability Backstop Process, which aims to procure 14.9 GW of new power for large loads by 2031. According to the announcement, they could unlock over one gigawatt of capacity in the region immediately. PJM's framework, released in mid-April, includes capacity from demand response and distributed energy resources as eligible options for servicing new loads, positioning VPPs and DERs as a potential turning point for broader deployment across the industry.
