Just crunching a few numbers:
DC fast charger revenue = 5 users per 24hr (avg) = $25 * 365 = $9125 * 155 chargers = $1'414'375 annually.
This is existing units only. New units are still being installed.
(possible additional revenue from advertising on "42 LCD)
This is at $5 per charge which will begin on June 10.
None members will pay $8.
Level 2 chargers = 8hrs per 24hr (avg) = $8 * 365 = 2920 * 10'000 = $29'200'000 annually.
This is existing units only, new units are still being installed.
This is at $1 per hour.
Non members will pay $2 per hour.
TOTAL POSSIBLE REVENUE FROM EXISTING CHARGERS ALONE = $30'614'375 ANNUALLY
On top of this you still have to add sales as well as commercial equipment chargers.
This is total speculation but does not seem like an unreal estimate.
Considering I have seen places with as many as 10 L2 chargers and 2 Fast chargers and people were still constantly running outside to move in to a spot as soon as it opened I think my speculation may be conservative for the future.
Especially with the amount of new EV's coming out this year alone.
