Pacific Gas and Electric Company and General Motors have announced a collaboration to pilot the use of GM electric vehicles as on-demand power sources for homes in PG&E’s service area.

PG&E and GM will test vehicles with bidirectional charging technology that can help safely power the essential needs of a properly equipped home. EVs play a critical role in achieving California’s goals for reducing greenhouse gas emissions and already provide customers with many benefits. Bidirectional charging capabilities add even further value by improving electric resiliency and reliability.

PG&E and GM aim to test the pilot’s first vehicle-to-home capable EV and charger by summer 2022. The pilot will include the use of bidirectional hardware coupled with software-defined communications protocols that will enable power to flow from a charged EV into a customer’s home, automatically coordinating between the EV, home, and PG&E’s electric supply. The pilot will include multiple GM EVs.

Following lab testing, PG&E and GM plan to test vehicle-to-home interconnection allowing a small subset of customers’ homes to safely receive power from the EV when power stops flowing from the electric grid. Through this field demonstration, PG&E and GM aim to develop a user-friendly vehicle-to-home customer experience for this new technology. Both teams are working quickly to scale the pilot with the goal of opening larger customer trials by the end of 2022.
