I added the discounted membership cost, again it's still pretty heavily marked up over the cost of that power being charged to the stations (which is way lower than you PG&E peak residential rates).
edit: You can head to the business BEV calculator and calculate for 200 cars doing full charges daily between 6am and 10pm (200 mile charges), every day of the month, the total monthly cost for power divided by the number of charges gets you to ~$10.50/charge power cost. So they're marking it up 80% in the cheapest case. If you only charge during peak hours (4-9pm) you could come out slightly ahead of the cost of energy assuming you paid for the membership.

Fast DC providers like Tesla and Electrify America attempt to offset this by colocating batteries at the station to shave utility demand. https://www.youtube.com/watch?v=JqqOM9nzz-A https://www.youtube.com/watch?v=JqqOM9nzz-A https://www.osti.gov/pages/servlets/purl/1543251 https://www.osti.gov/pages/servlets/purl/1543251

- thatfrenchguy 5y agoIf you ask PGE for 350kw, you'll see quickly how much more they'll charge you in demand charges :)
