Well, solar and wind are only usable when it is sunny or windy. The only way to make solar or wind power sustainable is to have ways to store the energy, like hydroplants or hydro pump stations. Right now, they are sabotaging the economy to build sustainable sources.

If you add storage to the network you can store the surplus renewable generation for later dispatch, Europe's largest just went online: https://archive.is/p9qsS

Their math is a bit off though... 300MW is not enough for 3.1 million households. That's 97W per household for like 2 hours.

To my understanding the use of nuclear would be to reduce the ammount of spread out battery stations that'd have to cover the base load when cloudy / at night.

There'd also be less overbuilding of solar as you have to build for winter weather and day length instead of summer if solar is supposed to cover everything

Covering winter with renewables would use longer term storage than batteries, for example hydrogen.
