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It's well out of date now that the Walpole project has been completed and is up and running for a few months now.

Yes, for one town that’s a solution, but not one for the whole of a nation.
