Alert readers will have noticed I mentioned run-of-river hydro as equally benefited by batteries as wind.
Another Bass Strait cable would be needed - though now there are multiple benefits, not just the grim politics of reliable supply to TAS consumers.
Mechanical batteries are going through their own 'Moore's Law' of of innovation and cost falls, with no end in sight. If it took 3-5 years of engineering and tunnel boring to build a TAS pumped hydro, where will battery pricing be then?
Please note, the TAS proposal does not increase generating capacity.
