We should be able to agree that 35 cents a kWh is pretty comparable to $2 an hour by L2 for most EVs on the road, meaning at least 6.6 kW OBC. After all, even if the commercial charger is 208V instead of 240V, 30Amps is a fairly typical amperage, giving 6.24 kW for a kwh cost of 200/6.24 = 32 cents a kWh. So if you are happy with the island per kWh charge, the L2 hourly rate should not bother you either.
The DCFC combined rate of 35 cents a kWh + $16 a hour does indeed sound expensive -- about twice as much as L2. OTOH it works out to a per mile charge not too different than what you pay for petrol. The big difference for most people though is that DCFC is a small fraction of their total miles while petrol cars pay that all the time.

On the island DCFC cost is $0.35 per kWh (plus parking fee's) which is reasonable seeing as we pay $0.10 / kWh as residential average rate.
Try the arithmetic again
Nothing wrong with the math. 5.8kWh on a 208V evse @ $0.35/hr is $2.03 . This should be charged in my opinion right now they are free causing the congestion problem. If your driving a phev c/w a 3kw charger this price will double with the proposed hourly chrge.
If I plug into a shared EVSE and another ev plugs in to the second head we will both be paying double as they are only rated at 6kWh total( not to many around but they are there, Chemainus for eg) .
I guess my beef is the DCFC charge of $16 PLUS the $0.35/kWh Plus parking.
