There is no grid that can be sustained on solar and batteries or wind and solar and batteries or wind and solar and pumped hydro and batteries. Possibly geothermal for base load could replace nuclear and natural gas plants, combined with renewal energy and battery storage.
Why not? Grid scale batteries will allow using solar/wind throughout the day and not only peak times, eliminating the duck curve problem. This is already only a few years away.
This only leaves "Dunkelflaute" as a concern, which can be solved with either hydrogen/gas etc. production and storage during peaks in the summer for example.
