South Australian blackouts due to over-reliance on wind and solar were predicted 2 years ago

February 13, 2017

I see that in South Australia some people have been complaining about the “record” heat with temperatures of 44ºC. Of course they take this as “evidence” of global warming. Never mind that some 120 years ago without any urban heat effects and without any industrialisation, the temperature reached 48-49ºC. It wasn’t global warming then.

In any event, South Australians and their elected representatives must get used to the fact that they have only themselves – and their political correctness – to blame. Winning greenie points seems to take precedence over common sense.

The SA blackouts caused by unreliable solar and wind were predicted two years ago in the journal Transactions of the Royal Society of South Australia, and every MP in the Parliament was told.

The Telegraph: 

100,000 SA customers blacked out because of reliance on unreliable wind and solar power in our network – more than a third of SA’s generation capacity.

IT is hard to disagree with the blunt assessment of Business SA that South Australia has been caught on electricity planning like a frog in boiling water. The story goes, with mixed results in scientific experiments, that a frog suddenly put into hot water will jump out but if heated slowly it will not figure out the danger.

The state was warned of the electricity-shortage crisis – and consequent blackouts – yet ignored the warnings, according to Business SA executive Anthony Penney.

“The most frustrating aspect of this most recent event is that it was anticipated by many businesses and other energy industry experts well in advance but, like the frog in boiling water, nothing happened in time,” he says.

This week the SA frog boiled. About 100,000 customers were blacked out because of the reliance on unreliable wind and solar power in our network – more than a third of SA’s generation capacity. ……….

Ben Heard, a doctoral researcher at the University of Adelaide also runs environmental non-Government organisation Bright New World – which supports the use of nuclear – explains the problem. He says the SA blackouts caused by unreliable solar and wind were predicted two years ago in the journal Transactions of the Royal Society of South Australia, and every MP in the Parliament was told.

“Back when wind generation was providing only 28 per cent of SA’s electricity supply, we flagged the risk presented by low supply in extreme heat conditions,’’ he says. Mr Heard said it was well known that extreme heat conditions in SA were accompanied by very little wind. “Our expectation at the time was that this would make it impossible to retire other generators from the market because of the security risk. Instead, the generators were allowed to retire, we took the risk, and we have started paying the price.”
