GM Plans 130,000-EV V2G Network and 1.5MW Sodium-Ion Storage
GM•General Motors plans to deploy over 250,000 bidirectional EVs with home backup and eventual V2G feed-in, aiming for a 130,000-vehicle network participating in grid services by 2030. The company will also develop 1.5MW/7.2MWh sodium-ion and second-life battery storage systems projected to save $3 million.
1. V2G Strategy and Fleet Deployment
General Motors is equipping more than 250,000 EVs with bidirectional charging to enable home backup power and future vehicle-to-grid feed-in programs. The automaker plans to standardize this capability across models like the Chevrolet Equinox EV and Cadillac Escalade IQ, targeting 130,000 vehicles in grid services by 2030 and 52,000 active in balancing schemes.
2. Stationary Storage and Second-Life Batteries
GM is collaborating with Peak Energy on stationary sodium-ion battery systems optimized for long cycle life and lower costs, and with Redwood Materials to repurpose EV battery packs for 1.5MW/7.2MWh installations. The first deployment at a Michigan facility is expected to deliver over $3 million in electricity savings over its lifetime.
3. Utility Partnerships and Software Integration
To advance grid integration, GM is working with Pacific Gas & Electric and DTE Energy on pilot V2G projects in Northern California and the Midwest. The company is also developing a unified software platform in its mobile app to manage vehicle charging, home energy systems, and grid interactions through a single interface.
