PG&E and General Motors collaborate

PG&E and General Motors are collaborating on a pilot project to reimagine the use of electric vehicles as backup power sources for customers

SAN FRANCISCO, California and DETROIT, Michigan. – Pacific Gas and Electric Company (PG&E) and General Motors (GM) today announced a groundbreaking collaboration to pilot the use of GM electric vehicles (EVs) as on-demand power sources for homes in the service from PG&E.

PG&E and GM will test vehicles with state-of-the-art bi-directional charging technology that can help safely power the essential needs of a properly equipped home. Electric vehicles play a critical role in meeting California’s greenhouse gas emission reduction targets and are already delivering many benefits to customers. Bi-directional charging capabilities add even more value by improving electrical resiliency and reliability.

“We are really excited about this innovative collaboration with GM. Imagine a future where everyone drives an electric vehicle and that electric vehicle serves as a back-up power option in the home and, more broadly, as a resource for the grid. Not only is this a huge step forward for electrical reliability and climate resilience, but it’s another benefit of clean electric vehicles, which are so important in our collective fight against climate change,” said Patti Poppe. , CEO of PG&E Corporation.

By the end of 2025, GM will have more than one million units of electric vehicle capacity in North America to meet growing demand. The company’s Ultium platform, a combined EV architecture and propulsion system, enables large-scale EVs for all lifestyles and price points.

“GM’s collaboration with PG&E further expands our electrification strategy, demonstrating that our electric vehicles are reliable sources of mobile power. Our teams are working to rapidly evolve this driver and bring two-way charging technology to our customers,” said Mary Barra, GM President and CEO.

How the pilot will work

PG&E and GM aim to test the pilot’s first vehicle-to-home compatible EV and charger by summer 2022. The pilot will include the use of bi-directional hardware coupled with software-defined communication protocols that will enable the energy to move from a charged EV to a customer’s home, automatically coordinating between the EV, the home, and PG&E’s power supply. The pilot project will include several GM electric vehicles.

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

Supporting Electric Vehicle Adoption in California

Increasing the adoption of electric vehicles can play a critical role in supporting California’s emissions reduction goals, as transportation is the largest source of greenhouse gas emissions in the state, contributing almost 40%. Passenger vehicles alone account for nearly 29% of the state’s total emissions. By 2035, 100% of California sales of new passenger cars and trucks will be zero tailpipe emissions.

One in five electric vehicles nationwide are on the road in PG&E’s northern and central California service area, where customers are often early adopters of new clean energy technologies. The electricity that powers electric vehicles in California comes from one of the cleanest energy mixes in the country. PG&E estimates that 93% of its customers’ electricity in 2021 came from greenhouse gas-free resources.

PG&E supports the adoption of electric vehicles by its customers. Through its electric vehicle charging infrastructure programs, PG&E helps reduce one of the biggest barriers to electric vehicle adoption: the lack of available places to charge. PG&E helps increase access to electric vehicle chargers for light-, medium-, and heavy-duty vehicle customers through its EV Charge Network, EV Fleet, and EV Fast Charge programs.

Additionally, PG&E offers electric rate plans tailored to EV drivers and provides tools such as PG&E’s Electric Vehicle Savings Calculator and Fleet Calculator ( and to help customers understand the costs when deciding to use an electric vehicle.
