Both France and Germany are net electricity exporters on an annual basis.
But when France sends surplus nuclear electricity to its neighbors that's supposed to be a plus for nuclear technology. When Germany sends surplus renewable electricity to its neighbors that's supposed to be a minus for renewable technology. Both nuclear and renewable generation are rigid in their own ways; neither is as flexible as gas powered generation, but of course neither has the substantial fuel costs or emissions of gas powered generation either.
