And that is not solar generated power.
Why not? We are about to get 3 hours of free electricity during the middle of the day because of the abundance of solar power. As thermal power stations close and we build more solar, this will become even more pronounced.

You tell me how a dam full of water stores solar & wind generated electricity like a battery?
That's what Snowy Hydro claim.
It's just farcical.
Quote:Snowy 2.0 is designed to "firm" or stabilize these regional renewable energy sources by storing excess power when the wind is blowing or the sun is shining, and releasing it when demand is high.
Quote:Snowy 2.0 does not use conventional chemical batteries; it is a pumped hydro energy storage project that functions as a "giant water battery". It stores energy by pumping water between two reservoirs (Tantangara and Talbingo) through a 27-km tunnel, creating 350 GWh of storage to dispatch power when needed.
Absolute garbage - it's stored water - it doesn't store energy.
It also evaporates during the day especially in summer.
What happens in a snowy winter in the Snowy?

The energy is only created when the water is released onto the turbines.
It's just fanciful playing with words.
You're really good at that as well.
