South Australia has built unreliable generators on one third of all homes in the state. They are expensive, encased in glass, and all fail at the same time, usually for breakfast, and definitely for dinner. They randomly fail when clouds roll in, but consistently fail all night long. When they do work, they all work together, producing an excess of energy when no one need an excess. In order to pretend that this surge is useful, a billion dollars of working infrastructure has to switch off, scale down, spin its wheels, and toss money out the window.
A few weeks ago, the State Energy Minister of SA, Dan van Holst Pellekaan, warned that the state is only a few years away from reaching “net negative demand” which is a fancy-pants way of describing the moment that solar power makes more energy than the whole state can use. His reassuring comment was “The grid blowing up is not the right term, but it simply will not work.”
With 250,000 unreliable generators in the state the midday excess is now so large it threatens to break things, drive up voltages, drive out reliable generators and generally muck up what was a finely […]
