Here's a £50k London parking space: https://www.rightmove.co.uk/properties/136662200#/?channel=R...
While that's an extreme, I would expect the cost of any urban parking space with a low speed charger to be dominated by the land, then the charger one-off install price, and thereafter electricity use is a pretty trivial cost.
Sydney will also charge you 3,000 $AUS annually for central parking spaces: https://www.revenue.nsw.gov.au/taxes-duties-levies-royalties...
I'm in Washington where electricity is cheaper, so 29 cents per kWh is not much cheaper than Tesla's superchargers. The closest one to me is 31 cents in the middle of the day and goes as low as 20 cents per kWh at night. I pay 8 cents per kWh at home, which is where I charge (at much slower speeds) unless I'm on a road trip.
