March 17, 2022: General Motors and Ford are to pilot the use of their electric vehicles as on-demand power sources for homes served by the Pacific Gas & Electric (PG&E) utility in California, PG&E announced on March 11.

PG&E and Ford will test the F-150 Lightning light-duty truck’s ‘Intelligent Backup Power’ bidirectional charging technology in the spring. Initial testing will involve a small number of homes.

The GM pilot will take place in the summer — including the use of bidirectional hardware coupled with software to enable power to flow from a charged EV into a home — “automatically coordinating between the EV, home and PG&E’s electric supply”, GM said.

After lab testing, PG&E and GM plan to test vehicle-to-home interconnection by allowing a small number of customers’ homes to receive power from the EV when power stops flowing from the grid. The goal is to extend to larger customer tries by the end of the year.

‘Multiple EVs’

GM CEO Mary Barra said the pilot program, using multiple GM EVs, further expands its electrification strategy, “demonstrating our EVs are reliable mobile sources of power. Our teams are working to rapidly scale this pilot and bring bidirectional charging technology to our customers.”

By the end of 2025, GM says it plans to have more than one million units of EV capacity in North America to respond to growing demand, using the company’s Ultium battery technology developed with joint venture partner LG Energy Solution.

According to the sustainable development scenario of the International Energy Agency’s Global EV Outlook 2020, released in June that year, the cumulative total of 16,000GWh of energy expected to be stored in EV batteries globally in 2030 “could actively provide energy to the grid at suitable times via V2G solutions”.
