Ten months ago our local 50kw chargeplace cost 15p/KwHr.
But it was abused by people hogging the chargers. One of the chargers always had a taxi plugged into it. Turns out a local taxi company was charging their fleet and not using the chargers on their premises.
They spoiled it for everyone. Now it costs 60p/KwHr and an overstay fine of £40.
It could be cheap, but always someone spoils it for everyone.
