Puff piece on solar wind and battery
Harsh reality
That is to say in the last week renewables averaged 28% of energy usage, and 4 out of 7 nights the grid was fossil fuel powered to some enormous extent, 90% or more, due to the wind drought. So they'd need 2.4 GW*16h battery for one night, 38 GWh, and currently solar might give them 8 GWh per day, so they need 5 times as much solar, and a $50B battery, say $50000 per connection, amortised over 10 years. Alternatively for half that they could do it with nuclear.
WA is in the interesting position where they have no interconnectors back to the "National" grid, hence have to be self reliant.
Cheers
