This continuing Series of Posts will detail the daily data for wind generation from all the Industrial Wind Plants on the major Australian Grid. This Series continues the data collection for all Australian wind power which was started on 1 October 2018. The original Series was started to show a definitive and accurate Capacity Factor Percentage for all the Australian wind plants on the main Australian power grid, and this new Series will continue to add to both of those Long Term Capacity Factor averages, shown directly under the Table below.

For an Introduction to this Series, and an explanation for the table, and the background, go to the following Post at the highlighted link. This introductory Post also shows the permanent link to all Posts in this Series.

Australian Weekly Wind Power Generation Data – Introduction And Permanent Link To All Data Post

The total Nameplate for all these wind plants changes as each new wind plant comes on line delivering power to the grid. That current Nameplate is 9854MW, and this is from the current total of 76 wind plants.

Comments for this week.

Wednesday – In perhaps one of the oddest things I have seen in the four years of collecting and detailing this wind generation data, the power generated across the whole day of Wednesday was exactly the same as it was for the day before, despite the Load Curves for power generation being totally different. The only difference for the day was that there was a slightly lower overall total power generation/consumption from every source for the day, and because of that, the percentage of power delivered to the grid by wind generation was ever so marginally higher.

Saturday – This was just another one of those events with the now relatively usual passage of those Large High Pressure weather systems across that area where there is the largest concentration of wind plants, in the South East of South Australia, and Central Western Victoria. In that area alone there is two thirds of all the total Nameplate for wind power here in Australia, and the total Nameplate in that area comes in at 6388MW. With that large weather system just sitting directly over that area, wind generation collapsed almost totally. The power delivered at the low point was just 192MW, from that Nameplate of 6388MW, a truly pitiful amount of power, and that meant that ALL of those wind plants in that area were only operating at a Capacity Factor of 3%, and they were all under 300MW total power delivery for nearly five hours. I’ll keep pointing it out when situations like this happen, and it’s relatively frequent in nature, because when it does happen, what does the Country do at times like this if wind generation is all there is to fall back on.

Sunday – Once again, with the High Pressure weather system hovering over that same area, there was yet again the collapse of wind generation, and this time it was more widespread because while the day before, that system hovered over that one area, this time it expanded further North taking in the wind Plants also in New South Wales. So when that total Nameplate of 9854MW is taken into account, total wind generation was lower than 1000MW for a full nine hours, and that was with the Capacity Factor lower than 10% for those nine hours. In that area where the greatest concentration of wind plants are, the low point was down at 230MW and those 51 wind plants with a Nameplate of that 6388MW were only operating at 3.6%. That nine hours of extremely low power delivery was during the day from 9AM until 6PM, those hours of large overall Country wide power consumption.

Weekly Update – As you can (now) easily see from the weekly totals for every day, now shown in the one place, there were only three days when wind was operating at a Capacity Factor higher than the year round average, and those two really low days meant that the average for the week was only 25.4%, and that was five percent lower than that year round average. That resulted in a marginal lowering of both long term averages for that Capacity Factor percentage, and again, notice how close those two percentages are.
