Canberra is moving toward full electrification. It’s been renewables (with offsets I think) since 2019. Hopefully more cities make the choice to grids with energy storage to reduce load on old coal and gas plants.

I think the problem with just looking at Canberra is that it can dump or import from NSW and the other parts of the grid, similar to SA, though on a smaller scale.
This looks at the entire network to see what is feasible, without being able to shunt excess generation or import from other networks.
This shows pretty well that we need two kinds of storage. One relativly high efficent, but more expensive for 9% of use cases. The other one large, low cost to built, but larger losses are possible. So I would say pumped hydro, batteries and similar storage in the first category, while biomass and hydrogen are good canidates for the second one.
However priotrity should be to go towards the reaching the 99%. That is a really good position for the rest and well 61% of global electricity still comes from fossil fuels.
Interesting, I never thought of it as storage. I do like that it is referred to as other.
It is the missing piece that we have the option to use fossil fuels, or biomass, or h2 or whatever we like or can come up with.
