^ While I agree that such expensive DCFC charging won't be used much by locals, as part of a road trip expense it is less of an issue, considering the other expenses of travel. If using lodging (hotels/camping) with destination charging, one starts out with a full battery each day. For shorter trips, say an out and back from home with one or two DCFC stops enroute, home charging covers a lot of the miles on both ends of the trip.
Nevertheless, I'd much rather see a flat 30¢/kWh, or something simple like that. By way of comparison, the residential rate for DMEA is about 11¢/kWh.

...And the cars which will impose the highest demand charges will pay the least per kWh
A technical note: that's not really how demand charges work. They are usually set by the highest power draw in any fifteen minute period in a month. So, if at any time the station draws the full 125 kW for fifteen minutes, that would set the demand charge at the maximum for the month. The actual DMEA proposed EV charge station tariff for three-phase stations of 50 kW or more:
Access Fee = $150.00/month
Energy Charge = $0.17000/kWh
Member Demand Charge = $2.00/kW
Idle Service Charge per month = $75.00/month
[I believe that this rate was formally adopted by the DMEA board in October.]
So, if the ChargePoint station drew 125 kW at some point in the month, the demand charge would be $250 for that month. It wouldn't matter how many times that threshold was reached. (It might actually be somewhat higher if the stations deliver 125 kW but they draw somewhat more than that.)
