There is nuclear next door in France. Just use that as baseload. Also you could build a bigger interconnect to Norway and dump excess power in pumped storage.

Many of the problems with energy in Europe are to do with insufficient capacity in international connections. Add interconnects to the east and you can sell excess wind and solar to Poland, Ukraine, and Russia, etc. Improve the connections to Spain and you can buy Spanish solar in the early evening when your own has stopped producing. Above all: stop trying to solve each country's problems alone, stop thinking that borders between countries are a problem.
