V2G (Vehicle-to-Grid)
Technology that allows EVs to discharge energy back to the utility grid, potentially earning revenue and providing grid services. Extends V2H beyond the home to the broader grid.
Why It Matters
V2G could transform parked EVs into a massive distributed battery fleet. If millions of EVs participate, the grid could access hundreds of GWh of flexible storage at peak demand.
