Thanks. 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.)

Did your powerlines get privatized?

This probably explains it better than I can: 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.

That'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.

When 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).

That 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.

Assuming a fixed cost is per kWh makes no sense and I'm quite confused that someone upvoted it.

We 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.)

Some Octopus energy customers have batteries and do this but it's a hefty investment.
