TL;DR
The Mobility House and Wallbox successfully installed the first residential bidirectional EV charger in San Diego, enabling vehicle-to-grid services. This development marks a significant milestone in US V2G adoption and grid strengthening efforts.
The Mobility House and Wallbox have completed the first residential bidirectional EV charging system in San Diego County, a key step toward wider Vehicle-to-Grid (V2G) integration in the US. This milestone allows EVs to supply power back to the home and grid, strengthening energy resilience amid grid strain, according to officials.
On this week, The Mobility House and Wallbox installed a Kia EV9 connected to a Quasar 2 bidirectional charger at a home in San Diego County. This setup represents the first residential bidirectional charger interconnected in the county, paving the way for broader adoption of V2G technology in US homes.
Russell Vare, VP of Vehicle-Grid Integration at The Mobility House North America, confirmed that this project achieved interconnection approval with the utility, a necessary step for V2G operation. The system can now export power, enabling EVs to act as energy assets for the grid and the home.
During the announcement at ACT Expo ’26, Dylan Gasperik, North America’s director of marketing communications for The Mobility House, emphasized the significance of this milestone for EV owners and utilities, noting that it opens new revenue streams and enhances grid stability.
Why It Matters
This development matters because it demonstrates the practical viability of V2G technology in residential settings, which could significantly enhance grid resilience and reduce energy costs. As EV adoption rises, integrating vehicle batteries into the grid offers a way to balance supply and demand, especially during peak periods or outages.
Industry experts, including Vare, highlight that this project signals progress toward mainstream V2G deployment, which could transform how energy is managed and distributed across the US, especially amid increasing grid stress and renewable integration challenges.

Background
V2G technology has been under development for several years, with pilot programs and utility partnerships testing its potential. Prior to this, most V2G efforts focused on fleet or commercial applications, with residential integration remaining limited. The recent installation in San Diego marks a shift toward consumer-level adoption, supported by regulatory approvals and technological advancements in bidirectional chargers.
The project aligns with broader efforts to modernize the grid and incorporate renewable energy sources, which require flexible, distributed storage solutions like V2G-enabled EVs. The ACT Expo ’26 serves as a platform to showcase these innovations and promote policy and industry support.
“This is an important milestone in the commercialization of vehicle-to-everything services for electric vehicle drivers. We have accomplished interconnection approval and enabled the system to export power, realizing the full value of V2G.”
— Russell Vare, VP of Vehicle-Grid Integration, The Mobility House
“This installation demonstrates that residential V2G is now feasible and scalable, offering new opportunities for EV owners to participate in grid support and revenue generation.”
