They export cheap wind-generated power to Norway when the wind is blowing, and import it back for a higher price when it isn't.

Norway has a lot of hydro which they used the revenues from North Sea oil to install. (Their geography and population density also helps.)

Technically, from your own numbers... Denmarks intermittent renewables (wind + solar) is 43%. Germany is 34%. Biofuel & Hydro are not intermittent.

I don't know, that's pretty impressive. Maybe they have international connectors with other countries? I think Germany buys Nuclear power from France? or maybe they have a super stable kind of wind.

Germany is a net-exporter of electricity to France. Especially in summer when nuclear reactors have to be shut down, because the water temperature in the streams they use already is too high or when the tide is too low, or in winter when the rivers freeze.
