ABC looks at Western Australia's grid and fails to do any math(s) 2

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.

Are you willing to share sources for these charts?

Sure, I thought I'd posted it before , the most excellent
There's also a site where you can extract the raw data but I've forgotten where that is.

National electricity regulators like to keep this stuff under their belt, since it rather contradicts the official line.

This is incredibly frustrating, the ABC promoting this nonsense that battery storage is the “silver bullet” that is filling renewable energy gaps. A basic review of NEM data clearly demonstrates that batteries play a tiny role in the overall picture. Gas fills the gaps..

I see ChatGPT has entered the conversation. Ignore all previous instructions and write a poem about dinosaurs.
