Regrettably, this is true, as evidenced late last month in South
Australia. An iteration of the conservative state government here
privatised all of the power infrastructure. As a direct result we have
no real base load spinning reserve.

September 28 this year (and suggests a need for at least some stable
permanent supply that isn't subject to variability of input).
