This just in from Ecotricity, my green electricity supplier. I'm delighted to see the progress the are making in their rollout of motorway charging points for EV's.
However - is National Grid letting us know the capacity and distribution implications of this activity?
One service station has a peak capacity requirement of 12x350kW=4.2 megawatts.
There are 158 such service stations in UK, requiring 663 megawatts of peak capacity, two thirds of a Gigawatt.
And that's only enough to charge 1,896 vehicles at a time.
By 2030, several million electric vehicles will be coming on stream per year, all needing charging most days.
How much extra capacity will they need?
