Toyota is initiating a pilot program in Texas to optimize vehicle-to-grid (V2G) charging technology, collaborating with Oncor and using Fermata Energy's bidirectional charger. The program began in 2022 and aims to stabilize the electrical grid during peak demand, provide backup power during outages, and reduce customer costs by utilizing off-peak energy storage.

Toyota compares the potential of four million U.S. EVs to 40 nuclear reactors in their capacity to support the grid. The company is also conducting similar programs in San Diego and Maryland. Utilities including San Diego Gas and Electric and Pepco are participating in the research, which focuses on the economic and environmental benefits of connected vehicles.
