Nobody seems to be considering Demand (KW) costs when talking about SC pricing. For high usage equipment like SCs, demand charges can be a sizable component of electrical costs.
Demand charges can easily account for 1/4th or 1/3rd of the entire monthly bill that Tesla pays for even an urban SC. The busier an SC is then those costs are essentially spread out over more charging sessions, slower SCs see the opposite.
Just because you pay X per kWh at home doesn't mean that is what Tesla is paying to charge your car at your local SC. Flat customer charges and taxes can add another 10% on top of that. (not trying to argue one way or the other right now regarding the price increase, just sharing info)
