And then you have Western Australia (specifically s.w. WA) where solar installation exceeds fossil fuel generation: https://www.abc.net.au/news/2019-12-01/rise-of-rooftop-solar-power-jeopardi= sing-wa-energy-grid/11731452 https://www.abc.net.au/news/2019-12-08/authorities-look-to-control-house-ro= oftop-solar-power-in-wa/11773436 Excess solar input with low demand means the spinning generator has insufficient load to maintain minimum output. As noted in one of the articles, they used to worry about excess demand. Now they worry about insufficient demand. S.
