Err, no, it's an actual system we built here to service an actual town to soak excess energy from midday solar and buffer an actual real town from blackouts.
The battery banks in Adelaide an elsewhere are real - you can kick them.
You can price these against gas peaker turbine plants, and then compare the robustness of mini distributed storage nodes against larger single point of failure fossil fuel gas plants.
I understand the Western Power link provided looks like media hype, it was put together years back at the start of the project with minal updates in the interim.
It's well out of date now that the Walpole project has been completed and is up and running for a few months now.
The point you appear to miss is that it works and can be easily distributed across a nation cheaply and robustly.
Single massive peaker plants Vs. many smaller battery parks and pumped hydro nodes.
It depends upon the population distributions, topologies, power grid, etc.
Adelaide is a state capital with massive battery banks and large amounts of renewable energy, they have long periods of self suffiency and export excess power to neighbouring states.
This is dull power infrastructure engineering reality, not woo woo imaginary hype.
