#3Great job! Did a similar study for Germany about 7 years ago based on their published 30-minute production and demand data and arrived to very similar conclusions. It's not as good as in Australia because both wind and solar in Germany is less reliable, also good enough.

#45 hours of grid-scale storage seems like a lot.

#5Interesting, but the title should mention it's localized to Australia so as to avoid arm waving from either side

#65 hours of grid-scale storage seems like a lot.
On its own, it does seem like a lot.
Thinking about the nature of renewables where I live, it seems so small as to be not worth mentioning; January will often have a week to several weeks of heavy cloud cover and little wind. A mere 5 hours of capacity is a pittance.
Australia, on the other hand, could easily make more sense, as I imagine the outback to be sunnier year round and maybe windier.

It also doesn't sound like actually enough. They never have outages longer than 5 hours?
And even with fully renewable sources they would never have periods longer than 5 hours without much generation?

California, on most days, is generating slightly less power from solar (~10GW) than all of Australia from coal (per https://electricitymap.org). Texas has over 130GW of renewables in ERCOT’s interconnect queue. There are challenges to solve for, certainly, but broad strokes the decarbonization roadmap is well defined and within reach. Velocity is a function of capital and technology investment.

#10The averages don’t tell me much. We need to look at percentiles with intermittent sources of energy. 99% still means 3 full days of blackout every year. So it needs to be sufficient to cover an even higher percentile (in fact I don’t even think there is an acceptable number of hours of blackout in a year). I would be curious how they get to that with energies that pretty much go to zero the week there is no wind.
