Where I am in London there're 7.7kW chargers built into some lamposts. It's about 30-40p per kWh depending on when you start. There's also a couple of other providers with roadside chargers in random residential roads. I think they've got the scaling about right for the current demand but if everyone in the area had an electric car it wouldn't work.
I can go 290 miles at £0.016/mile when charging at home. At the (expensive) motorway services it's then £0.15/mile to rapid-charge. The unleaded at that services is £1.60/l so at 42 mpg (guess) it's about £0.17/mile. The EV version of my car is more expensive than petrol but it's not 2x. A petrol car is more expensive to run and fuel (in the UK, at least).

- sokoloff 3y agoThanks. Is that energy and delivery-of-energy combined for 7.5p/kWh? (Here we are charged separately for each of those tasks and, for me, the delivery of energy is over 59% of the total bill. Any alternate supplier is competing only for the supply of energy.)
- sitkack 3y agoDid your powerlines get privatized?
- sokoloff 3y agoThis probably explains it better than I can: https://www.mass.gov/info-details/what-do-i-need-to-know-about-my-electric-supply-options-in-massachusetts https://www.mass.gov/info-details/what-do-i-need-to-know-abo... As far as I know, the distribution has for a very, very long time been managed by a private, regulated monopoly utility.
- nsteel 3y agoThat's the energy only. The delivery of it is fixed charge which doesn't come into this analysis since it's unavoidable in either case.
- sokoloff 3y agoWhen you're computing your total cost per mile to compare against petrol or against a commercial fast-charging alternative, it does come into the analysis (assuming it's a per-kWh cost rather than a per-month fee).
- nsteel 3y agoThat assumption is incorrect. I said > fixed charge I pay the same fixed (daily) standing charge regardless of how much electricity I use. This is normal here. To include it in the calculations makes no sense.

- Dylan16807 3y agoAssuming a fixed cost is per kWh makes no sense and I'm quite confused that someone upvoted it.
- sokoloff 3y agoWe have competitive supply here. The charge for distribution is fixed with regard to which energy supplier you choose, but is not fixed with regard to energy consumption. I asked, because if I chose Octopus supply, my energy supply price per kWh would vary according to the supplier but the price per kWh for distribution would not. (And Octopus would naturally only quote the price that they are charging for the part of the total picture that they're involved with.) Being the total (excellent!) rate, I'm a little surprised that Octopus customers aren't running LiFePO4 battery banks to power their daytime usage from the nighttime tariff.
