This Post details the daily wind power generation data for the AEMO coverage area in Australia. For the background information, refer to the Introductory Post at this link.
Each image is shown here at a smaller size to fit on the page alongside the data for that day. If you click on each image, it will open on a new page and at a larger size so you can better see the detail.
Note also that on some days, there will be a scale change for the main wind power image, and that even though images may look similar in shape for the power generation black line on the graph when compared to other days, that scale (the total power shown on the left hand vertical axis) has been changed to show the graph at a larger size to better fit the image for that graph.
Tuesday 14 June 2022
On this day, the site I use for data collection added seven new wind plants to the existing plants here in Australia. Those new wind plants are:
Bango 999 Wind Farm – 85MW in New South Wales – code BANGOWF2
Kennedy Energy Park Wind Units 1-12 – 43MW in Queensland – code KEPWF1
Lincoln Gap Wind Farm – 86MW in South Australia – code LGAPWF2
Port Augusta Renewable Energy Park – 210MW in South Australia – code PAREPW1
Diapur Wind Farm, Units 1-2 – 8MW in Victoria – code DIAPURWF1
Murra Warra Wind Farm Stage 2 – 209MW in Victoria – code MUWAWF2
Stockyard Hill Wind Farm – 531MW in Victoria – code STOCKYD1
This adds a further 1267MW to the total Nameplate for wind plants here in Australia, for a new Nameplate total of 9854MW, and the data from this day to the next change will reflect the increase in that Nameplate number.
Total Wind Power Generation
This image shows the total power generated across the whole day by every wind plant in this vast AEMO coverage area for Australia.
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.
Note that the shape of this wind power load curve does not follow the shape of the main load curve for total power generation, and that is seen in the image below, the solid black line across the top of the image for that graph. Wind power generates its power only when the wind is blowing, hence it does not follow the actual power generation Load Curve, which is also the the exact same shaped curve as for actual power consumption.
For this data, I have added the times for the daily minimum, and the daily maximum, to show how they do not correlate with the actual times of minimum power consumption (around 4AM each day) and maximum power consumption, the evening Peak. (at around 6.40PM in Winter and earlier during the Summer Months.)
Daily Minimum – 2112MW (12.01AM)
Daily Maximum – 6207MW (11.15PM)
Average Wind Generation – 4189MW
Total Generated Power – 100.53GWH
Percentage Supplied By Wind Power At The Low Point For The Day – 8.9%
Percentage Supplied By Wind Power At Peak Power For The Day – 5072MW of 31595MW – 6.00PM – 16.05% (Mid afternoon Peak with maximum rooftop solar added was 28725MW at 11.30AM)
Average Percentage Of Overall Total Power Generation – %
Daily Operational Capacity Factor – 42.51%
Wind Power Generation Versus Total Power Generation
This image shows the total power generated from all the wind plants in this AEMO coverage area, and compares it to the overall total generated power from every source of power generation, which is the black line at the top of the graph. Wind power is the green coloured area, along the bottom of this graph.
While the green colour in this image looks to be a different shape to the graph above, keep in mind here that the scale is completely different, and that green coloured Wind total is the same as for the image shown above, only with the scale changed so it can fit onto the graph.
- Finding Wind Power Average – On the graph, there are 25 hourly time points, starting with midnight and finishing with midnight. I have added the total at each of those hourly time points together, and divided the resultant total by 25 to give an average in MegaWatts. (MW)
- For total power in GWH, multiply the average daily power by 24, and then divide by 1000.
- For the Capacity Factor, that is calculated by dividing the average wind generation by the current Nameplate and then multiplying that by 100 to give a percentage.
Comments For This Day
As I mentioned above, there were seven new Wind Plants added to the data from today. There was an increase in Nameplate of a quite large 1267MW. Still, even with that increase, and good wind conditions, the high for this day was still lower than the highest ever recorded wind Peak. The average for this day was 4189MW, and that gave wind generation a daily operational Capacity Factor of 42.5%, and that was twelve percent higher than the year round average. Wind generation climbed steadily across the day and was in that rising phase when the usual time of the evening Peak of maximum power consumption came around, and at that time, wind was delivering 16% of all the generated power from every source. With that fairly steady rise across the whole day, that meant there was a huge difference between the low for the day and the high, and for this day that gap was a very large 4095MW.
