The secret is to get in first and make the comment, 'Us Port supporters are used to a Power outage we have been experiencing one since about June'. If you don't you will leave yourself open to all sorts of snide Power jokes.
On a more serious note it is a matter of national concern that a cataclysmic weather event 300 km north of Adelaide can take out a whole state. Image if a terrorist decided to target a couple of strategic pylons, they could black out the nation.
From what I could gather from the ABC last night a cyclonic wind took out power pylons at five different locations across south Australia. This resulted in a serious imbalance in the South Australian power network and the automated system did what it was supposed to do- shut down. This is known as islanding and South Australia was isolated from the National Grid. There was no problem with either of the two interconnectors. Once the areas of damage were identified and isolated South Australian Power Networks under direction from Electronet were able to restore power. The reason it took so long was that the power had to be switched on in stages as flicking the switch would have resulted in a surge and the auto shut down would have re occurred.
At our house we were without power for eight hours. There was little or no petrol, people were trapped car parks and many supermarkets were affected. As expected the Seaford train and trams stopped running. I would not be buying any perishables from a supermarket unless they can show they have auxiliary power.
Full marks to ABC 891 for keeping us up to speed during the night. Full marks to emergency services, the police and the majority of motorists who used common sense at intersections etc.
Latest info is that 22 power transmission points were affected around the Port Augusta area and that Adelaide was subjected to over 80,000 lightning strikes. What sort of wind bends a power plyon to the ground ? That has to be cyclonic.
The 000 network is unavailable in some areas.
The wind has eased down south where I am but is expected to pick up again tonight.
