The signal
Utilities are running pilots, especially with school buses and commercial fleets that park predictably. Few offer permanent rates that make participation clearly worthwhile.
Where it could lead
Fleets of EVs could act as a large distributed battery for the grid. Without payment models, that potential goes unused.
Evidence that would strengthen the case
- Utilities offer permanent, clearly profitable vehicle-to-grid rates
- Companies that bundle many vehicles and sell their power to the grid
- Fleet operators earn meaningful revenue
What could prevent it
- Payments too small to justify the hassle
- Battery warranty and wear concerns
- Home and grid batteries fill the need more simply
