Pumped Hydro Energy Storage

In public policy, there are many dog’s breakfasts presented as considered initiatives. Rarely, though, are we served up such a self-contradictory, irrational and generally talentless a dish as the new β€œenergy intervention” announced by South Australia’s Labor government on March 14.

Aimed at side-stepping conservative attacks over recent power cuts, the government’s plan makes some provision for storage back-up to underpin wind and solar. But mainly, the $550 million scheme consists of large-scale concessions to fossil fuel interests β€” in this case, the gas industry.

One outcome of last year's inquiry into the Morwell Mine fire in Victoria's Latrobe Valley was the discovery that the default plan for β€œrehabilitating” the mine would be to let it fill with water naturally, perhaps to become a recreational lake. The hitch: it would take more than a hundred years to fill naturally and the water quality would be terrible due to pollution from coal seams.
