We have the problem of stable high-pressure polar air masses potentially parking over the country. Whenever that happens, we get 2 weeks of dead calm, coinciding with the coldest weather that occurs in the country. At the time of the year when there is no solar.
That's where inter-country interconnects, storage and gas come in, which can only be reasoned about through simulations.
These weather systems are quite big indeed. It's cold and calm in the neighboring Scandinavian countries as well and typically in Central Europe too.
