The large batteries from each school bus, ranging from 125 kWh to 250 kWh, may be aggregated at each site to provide the grid with much needed flexibility, and in the future, can also serve as emergency back-up.

V2G is often discussed for when the EV market gets more penetration, but buses really are the perfect asset for this-- school buses can charge during the afternoon when solar is most available and affordable and at night when wind then picks up. Given their larger batteries, too, you're looking at some real load management opportunity

Roger - interesting post, suprising how small the bus batteries are.  The larger Tesla Model 3 battery is 72 KWH and as an owner, it does not get drained daily.  Getting all of this un-used battery capacity into the market would address many issues.  There are technical issues, but I would expect that the market and behavioral issues will be tougher.   With EV2G solutions, EV's would improve the grid, not hurt it.

"Nuvve began using the microgrid’s 5 MWh lithium-ion battery, which historically focused on the management of campus energy peaks, to bid into wholesale energy markets in June 2020."

Roger, the power output of Nuuve's 5MWh battery is four orders of magnitude too feeble to remediate Southern California's energy shortfall in late summer afternoons - the addition of Bluebird bus batteries, notwithstanding.

The ineptitude of the shutdown of San Onofre is only outdone by that of trying to fix CPUC's mistake by borrowing electricity from school bus batteries. Has it really come to that?
