Update triggered by a comment from Yarpos. Longterm windwatchers Paul Miskelly and Anton Lang have pointed out that the wind practically disappears every time there is a high pressure system over SE Aust. This has only just recently become clear to me because I have not watched the weather patterns for years since the time when it was a daily concern on the farm.
When you get the relationship it is plain that the phenomenon of extended periods with next to no wind should have been common knowledge among meteorologist for ever. Maybe so well known that nobody even talked about it, like we don’t talk much about the sunrise and sunset until they become important for some reason or other. So where was the BOM when windpower got the blessing of government by way of subsidies and RE mandates? And who were the people who might have done due diligence by consulting BOM records?
Back to the topic of the original post….
You could not make it up but The Guardian and UTS academics can!
In the real world we are just experiencing the ninth (9th) episode this month when the performance of the windmills in SE Australia fell below 10% of capacity for several hours. The longest spell was 33 hours on the 5th and 6th.
This is South Australia this evening, negative a few hours ago and still zero.
Victoria is zero. New South Wales is doing better at 3% of capacity. The blades are moving in Queensland and Tasmania, 20% of capacity but they contribute next to nothing in MW. The total at present from the wind is 370MW towards a demand of 28.5GW, that is 1.3%!
This is the source, a 24 hour display, not a screen shot so it will change. Saturday update. SA is getting more wind today but not Victoria at present.
