Simple question- How much battery capacity is needed?, page-27

So in the worst single week ever 'other' needed to provide 18.6% of power based on his assumptions, not the actual AEMO path with their level of wind, solar etc etc. The average over the 3 year period was less than 4%

So the alternatives are:
1) Factor in additional generation capacity
2) Factor in more storage via batteries or hydro
3) Include green hydrogen as an additional renewable source or other renewables such as biomass to cover a proportion of 'other'.

All types off power generation need to cater for the highest demand / worst case scenario i.e you always have greater than 100% capacity.
That model had 118% capacity based on increasing wind generation by X5, rooftop solar by X2.9 & utility solar by X4 based on 2022 levels.

The aim is not to get to 100% renewables all the time, the aim is to achieve net zero emissions.

So the gap is easily bridged.
