Pretty disgraceful of the federal government to use this event as political point scoring against renewables:

Don't be silly, it is obvious the extra weight of the electricity from wind turbines exceeded the safe working load of the transmission lines. Turnbull is one of the foremost politicians with an intimate knowledge of the physics of the modern world, and has the ability to get any number of half wit voters to believe any old crap. Until they wake up.

Not sure I agree with you there. I think South Australia imports a lot of its electricity when the wind is not blowing and was probably importing a lot when the powerlines linking Adelaide to the rest of the Australian states in the National Electricity Market got blown over. Existing generation probably could not cope.

They probably should not have shut the coal plant before they have some decent storage or a DC link to Tasmania.

Must be interesting starting a grid on mostly wind power.

See this website http://reneweconomy.com.au/nem-watch for more information on the generation mix for All Australian states (except NT which is all gas anyway).

Here's another good one that tells you the last 24 hours generation for each power plant including wind farms. http://energy.anero.id.au/wind-energy
Keep a watch on the solar section. There are 12 solar power plants currently under construction in Australia in addition to the four currently in operation.

Nope, can't accept any of that. It was all the wind generators generating so much wind it blew over the pylons. Turnbullshit for PM. Or Barnaby Joyce, he has got it right, it's the renewables wot dun it, innit?


(Why are these ignorant twits allowed to talk such absolute rubbish?)

I would suggest that market forces were in fact responsible for the black out. The transmission towers were clearly not up to the job and had not been sufficiently over specced or maintained as a penny pinching measure due to pressure from the bean counters to maximise profitability. This could be reflected in the built design, workmanship and the quality of the tower components.

They may have been designed to survive a notional hundred year storm only hundred year storms are becoming less notional and coming along more and more frequently. This has implications for overhead transmission systems globally.
