A new pilot in Arizona is giving homeowners the chance to turn their electric vehicles (EVs) into standby power sources for the grid—making it the first U.S. residential program of its kind. Partnering with local utility Salt River Project (SRP), participants install bidirectional chargers that not only fill up their cars but also feed stored electricity back into the grid when demand peaks. By tapping into the growing fleet of EVs as a distributed energy resource, the initiative hopes to bolster grid stability during times of high usage or instability.
Over the course of a yearlong trial, homeowners will earn financial incentives for taking part and sharing their charging and discharging data. SRP will track how effectively these vehicles support the grid, with an eye toward broader rollout of vehicle-to-grid (V2G) technology nationwide. If successful, the program could pave the way for cleaner energy solutions and new income opportunities for EV owners.
