Dunkelflaute is extremely rare if you have a sufficiently large grid [0]. That's the beauty of european collaboration, you can have german and spanish renewable jump in for each other, norwegian pumped hydro in the super rare case that neither have wind or sun, and french nuclear, should that happen while the storage is empty and you don't feel like reducing steel production for the day (which is btw also a totally valid way to balance the grid). 0: https://de.wikipedia.org/wiki/Dunkelflaute https://de.wikipedia.org/wiki/Dunkelflaute
