Overview
- The three companies announced the coordinated virtual power plant on June 24, 2026, saying it would aggregate millions of existing home batteries, smart thermostats and other connected devices to offer more than 16 gigawatts of flexible capacity.
- Company statements say the pooled resource draws on hundreds of thousands of residential battery systems from Sunrun and Tesla plus more than 8 million smart devices managed by Renew Home, which they describe as the largest distributed power plant in the U.S.
- The partnership says more than 300 megawatts of capacity are ready now in Virginia’s Data Center Alley, with at least 500 megawatts expected there by 2030 and multiple additional gigawatts buildable nationwide.
- The firms have committed capacity to PJM’s proposed Reliability Backstop Process, which they say could unlock more than 1 gigawatt immediately if PJM accepts the offer, but that outcome remains subject to regulatory approval.
- Sunrun stock jumped about 16% on the announcement and the companies are marketing capacity to hyperscalers via a central sign-up process, while their claims depend on customer enrollment, commercial contracts and pending regulatory clearances.
