Re: Electric car grants

Electric charging for the masses needs a MASSIVE upgrade of the entire grid.

The whole system - local distribution networks, HV transmission lines, and most critical of all, generating plant. In the UK thanks to the tree huggers, National Grid have to count wind power as part of the total capacity to keep the lights on in a "derated" plant scenario. Put simply, we don't actually have enough depatchable capacity to keep the lights on if there's a particularly cold winter, and we have any generating or transmission problems at the peak demand periods.

And that's with current levels of demand. As a rough guide, each electric vehicle uses about the same power annually as an average UK house. You're not going to need much of the road fleet to be EVs before they are dramatically exacerbating the problems of lack of reliable generating plant.
