If they can get Comcast for this purpose they probably spend less than $100 a month + whatever maintenance contract they have to manage the entire setup.
Even assuming it costs $200/mo for business class internet (cost is typically closer to $100/mo for business DSL/cable-modem service), install costs are usually minimal to free. This setup will support dozens of customers concurrently.
Now let's say you want to install 4 L2 stations. Chargepoint stations cost ~$7k for their new dual-plug stations. Installation cost to trench and run electricity can typically cost about $10k. Yeah, so now you're up to ~$25k just for the install. Let's say they have a 20% utilization factor (probably generous) - you might deliver about 50-60 kWh / day or about 1500 kWh/month. At a cheap $0.10/kWh that's $150/mo, but could be 2x that. If you are paying demand charges
, you will probably incur about 10-15 kW of demand charges
/month - that might cost another $100-400 / mo depending on your utility and demand charges
The installation cost is the cost of 10 years of internet service and the utility costs are 2-5x more and you will only be able to serve up to 4 customers at a time.
Now try to run the numbers for a couple QC stations - install costs are 4x higher per plug (unless you can get a free charger from Nissan
in which case it's pretty reasonable they estimate $13k for a QC station - I'll take two!) and if you have to pay demand charges
those could easily be over 5-10x more per month.
It's easy to see why building a viable business is very difficult when coupled with the fact that it seems that too many people too short sighted to see that public charging is going to cost a lot more than home charging just like the cost of a Pepsi or coffee at home costs a fraction of what you pay at a restaurant and yet the restaurant business seems to move quite a few "overpriced" beverages.
