I think 8 cents is too much of a generalization...

Here is the commercial rate sheet from PGE...

Basic charge $30 or $40 (single or 3 phase) - how many chargers are there? DC Fast charger?

Transmission charge: $0.91 per kW of monthly on-peak demand...That could be $20 if there are a few Level 2's or $60 if there is DC Fast charging involved

Distribution charges: $2.65 + $1.95 of monthly on-peak demand...So about $40-45 for a few Level 2 stations or about $100 if DC Fast charging is there

Energy and System usage charges: 6 or 7 cents per kwh total depending if on peak or off peak

There are other rate schedules that add other components, looks like a few percent...

Summarizing above - some rough numbers: For a few L2 stations, it would cost $30 + $20 + $40 + 6 cents per kwh + a few percent for fees/programs

If they dispense 500 kwh per month, that would be $120 plus fees (call it $140 for 500 kwh). That works out to be 28 cents per kwh. Of course, these are rough numbers.

If there are DC Fast chargers involved, it would cost $40 + $60 + $100 + 6 cents per kwh + a few percent for fees/programs.

If they dispensed 1,000 kwh, that would be $260 plus fees (call it $280 for 1,000 kwh). That works out to be about the same 28 cents per kwh (higher fixed fees but more throughput).

To the cost of the energy bill, don't forget to add:

* insurance

* back end network

* customer help line

* billing

* maintenance

* administrative costs

* revenue share with host

* credit card fees

* PROFIT

Looks like they charged you roughly 11 cents / kwh above and beyond their energy costs for all of those items above including profit.....

I did all of this to show you that they are not raking in as much money as you assumed...It's a tough business.....
