Stop These Things
Thanks to its ludicrous attempt to run on sunshine and breezes, South Australia has just experienced yet another Statewide blackout. SA’s vapid Premier, Jay Weatherill and what passes for media in this Country ran straight to the periphery, blaming everything except the bleeding obvious (see this piece of infantile doodling from wind cult central – the ABC).
STT’s SA operatives tell us the blackout occurred during a blustery spring storm (heavy rain, lightning and surging, gusty wind). The power supply went down across the entire State at precisely the same time (a little after 3:30pm). It took more than 5 hours to restore power to a few parts of the State, and many regions remained powerless for much longer than that.
True it was that lines were damaged in the mid-North around Port Augusta, but that doesn’t explain why the whole State’s supply went down. Grids are designed with with a level of redundancy, and to avoid complete collapses by isolating damaged sections, in order to keep the balance up and running.
For those truly interested in the cause, what appears in the graph above – care of Aneroid Energy – gives a clue as to the culprit.
SA’s 18 wind farms have a combined (notional) capacity of 1,580MW.
On 28 September (aka ‘Black Wednesday’), as the wind picked up, output surges by around 900MW, from a trifling 300MW (or 19% of installed capacity) to around 1,200MW.
As we explain below, electricity grids were never designed to tolerate that kind of chaos, but it’s what occurs in the hour before the collapse that matters. Read article
