France has an amazingly developed grid, with a lot of nuclear. But I think there's a risk of seeing grid make ups as "one size fits all". Norway and Sweden do well with huge amounts of hydro storage, but few countries have the geography for that level of hydro. Similarly, the UK has an abundance of offshore wind (especially in Scotland), so further developing that (rather than focusing heavily on nuclear because it works in France) is by no means a bad idea.

Hydro is great for long term storage, but the potential is too small and sparse on the globe to be a scalable solution.
