What happened
Sunrun and Voltus announced a multi-year arrangement intended to aggregate residential solar-plus-storage resources in PJM and MISO and use them as flexible capacity connected to growing data-center demand.
What this means for homeowners
The deal illustrates a broader shift in battery economics: a home battery may provide backup and bill savings while also earning value as part of a larger grid-services portfolio. Homeowners still need to understand who controls dispatch and how participation affects backup reserves.
Key points
- The arrangement targets residential storage resources in PJM and MISO regions.
- Aggregated batteries can reduce demand or provide capacity when the grid is constrained.
- Customer contracts should clearly explain dispatch rights, compensation and reserve settings.
