In Germany when there is a surplus of power, they pay you to use (or store) it.

Once for importing, and once for exporting.
Now that should encourage people to install batteries thus solving the intermittancy problem!

It hasn't a hope of solving that problem, or even making a noticeable difference. A little basic maths will show you how unrealistic such an idea is.
