Pretty much... I don't think any of the third party companies are making money yet.. they are mostly reliant on grants from Fed Govt Arena and some State Govts.
They have to (typically) rent the site.
The install of those 350kW chargers is $100k+ ($40k + for 50kW), plus maintenance when people stretch cables or vandalism.
And on top of the wholesale price, you also need to cover demand charges (basically max draw out of a unit) - so an operator's worst case scenario is 2 cars arriving at a lightly used station at the same time.
As above Tesla is currently 51c/kWh.
In the past 12 months they've gone 42-52-47-51.
Chargefox is 32/40c/kWh (lower rate with roadside membership). Evie is 40/60c/kWh (higher rate for 350kW) and some of the lightly used Tas stations are even higher.
tbh they should just build i.e. 70-75 kw charging stations. its more than fast enough for most people traveling...
tritium has finally released their 75kw charger and i hope we will see a few of those at decent electricity prices.
