A few months ago I read that there are applications to connect more battery capacity to the German grid than the country's peak usage. If all of that is approved, Germany could run 100% on battery powered (at least for a few minutes). I can see why... If battery operators can buy power at below-zero prices now and then, profit should not be a problem.
