Smart meters and electricity storage
I had a small thought on this over the weekend. It's an idea that's been floated a few times - when we all have electric cars, these can be used to provide "surge" supply onto the grid, rather than using pumped storage hydro and similar. That way, it's all nicely distributed, and the end user picks up the tab for providing the infrastructure. The thing is, though, that if you've spent 15p/kWh (for example) charging your car, you don't want to sell that back to the grid at wholesale 4p/kWh (or whatever it is). That gives the supplier a huge incentive to draw electricity from you.
So, an export meter won't work.
What you want in this case is a meter that'll run backwards, to fully refund you for the electricity you're providing. Only they've got rid of all of these.
Not sure there are enough faces to palm over this whole project.
