That might be true for net flows, but it seems that German production does not meet demand at nights very often, as per these statistics: https://www.energy-cha

I do think that situation will get worse with increased PV installations, as they don't produce during nights. Grid storage is going to be needed. Of course it's an open market and the German expensive production such as gas turbines will not produce if cheaper power can be imported.
