fair point bastjose. I'm only familiar with the Hunter region plants. Liddell has dams. very large dams. and running 2 coal plants off their water supply.

moreover AGL is planning to construct dams from the old coal pits for pumped hydro.

there are many coal pits, great gaping ulcers int eh crust of the earth. these could provide enough water storage if they're near enough.

but yeh, I get your argument. some sites might not be so suitable.
