General Motors Co. in Detroit and San Francisco’s Pacific Gas and Electric Co. 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 cutting-edge bidirectional charging technology that can help safely power the essential needs of a properly equipped home. Bidirectional charging capabilities add even further value by improving electric resiliency and reliability.

“We are really excited about this innovative collaboration with GM. Imagine a future where everyone is driving an electric vehicle — and where that EV serves as a backup power option at home and more broadly as a resource for the grid,” says Patti Pope, CEO of the PG&E. “Not only is this a huge advancement for electric reliability and climate resiliency, it’s yet another advantage of clean-powered EVs, which are so important in our collective battle against climate change.”

By the end of 2025, GM will have more than 1 million units of EV capacity in North America to respond to growing demand. The company’s Ultium Platform, a combined EV architecture and propulsion system, enables EVs at scale for every lifestyle and price point.

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, the companies 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, the aim is 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.

“GM’s collaboration with PG&E further expands our electrification strategy, demonstrating our EVs as reliable mobile sources of power,” says Marry Barra, chair and CEO of GM. “Our teams are working to rapidly scale this pilot and bring bidirectional charging technology to our
