The are they are eye wateringly expensive. So expensive that no commercial interest wanted anything to do it when renewables are so cheap. Even the LNP plan was based around the state building them because the private sector wouldn't touch it.

And even if you somehow manage to get them built - they have the same problem that coal does.. maybe worse. They can't really be throttled. So now you've got the same problem - too much electricity during the day. What should we do with all the renewables?

Grid scale storage is an easier and cheaper solution compared to nuclear and it actually addresses the downside of renewables.

With wind and solar very low for:

• four-hour periods being "Very common (nighttime/low wind days)"
• One to four days - Occurs a few times per year
• 8days + Rare- every 7 years or so

For the current Australian grid, which uses roughly 20-25 GW on average, that would require roughly 4,200 GWh of storage—about 12 times more than currently planned for several days back up. Thas roughly 1,000 times larger than any single battery project currently being built in Australia.

Batteries last for several years. Ditto for solar panels, Inverters and batteries, Nuclear is 50-100 years

The longest significant "wind drought" recorded recently lasted 8 days (May 20-27, 2024). Snowy Hydro is (350 GWh)
Nuclear is cheaper by far
