Depending the utility, what harms remote charging rates is something called Demand Based tariffs.
For our utility, it's $200 a month + $17.32 per kW peak + 0.08 per kWh IIRC.
So to run a 100kW single charger in Southern California it will cost $1373 a month for the first car that uses it. So if the charger gets a 1000 customers in a month, no problem, $1.37 a customer for overhead fees then sell the electricity at a profit. If 100 customers use it, you've got a problem. $13.70 per transaction overhead.
The same thing would happen with two 50kW chargers that could be used concurrently.
And this does not include cost of capital or operational costs like maintenance, advertising, business license, taxes, etc.
So only very busy charger can make money in a Demand Tariff region, which is spreading like the plague.
This is why you see few remote location DCFCs by private companies, and why you see 1 or 2 chargers, not 12 like Tesla.
To make EVs remote charging viable we need a Congress and States who actually want EVs. Not just talk, ACTION. Eliminate Demand Based mandatory tariffs for EV chargers. Make it a choice.
This is one of the many reasons I say California is the most Anti-EV state in the country. I can't put a bigger than 4 kW single charger at work now. If I do, I get pushed into Demand tariffs, and my electric bill doubles because I have "cycling high draw equipment" like 4 AC units and a 10hp rotary air compressor. By law of averages, they will all come on at the same time at some point since the compressor is not optional, and the ACs are used to stabilize a 68-72°F laboratory, 24/7/365. Yes, they are heatpumps that run all night and day in cycles with 12 thermostat locations. I am so close to the Punish Barrier (20kW Demand), that I would go over if I pulled 7 kW continuous EVSE loading.
Either our government is inept, uninformed, uncaring, or just plain hypocrites, allowing a monopoly to do this to EV chargers in an area with over 25,000,000 autos, perhaps more EVs than any other US utility is Anti-Environmental Activity. Not neutral. It stopped the California Corridors we paid for. Since H2 stations and L2 chargers don't suffer this brutality, they built those instead and pocketed the rest in 'studies and committees'.
