The real exciting feature would be vehicle to grid ability to buffer the grid. If the utility could benefit from this, they could contribute to the purchase price by whatever amount their operating savings would be.
Having 300 buses with 200 kWh batteries means 60 MWh available. Would be a huge benefit to supplement peak production which occurs around 6pm.

As noted in my post above that is what Dominion Energy did. They paid the additional cost for a pilot program with 50 buses. For that ~$500K invested they are getting about 11 MWh of battery storage.
