Australian Daily Wind Power Generation Data – Friday 17 June 2022

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.

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 – 319MW (4.00PM)

Daily Maximum – 1302MW (11.59PM)

Average Wind Generation – 709MW

Total Generated Power – 17.01GWHGWH

Percentage Supplied By Wind Power At The Low Point For The Day – 1.2%

Percentage Supplied By Wind Power At Peak Power For The Day – 487MW of 29035MW – 6.05PM – 1.68%  (Mid afternoon Peak with maximum rooftop solar added was 26575MW at 12.30PM)

Average Percentage Of Overall Total Power Generation – %

Daily Operational Capacity Factor – 7.20%

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.


  1. 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)
  2. For total power in GWH, multiply the average daily power by 24, and then divide by 1000.
  3. 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

Barely two days back new wind plants were added to the data from the grid, and this increased the total Nameplate for wind power to the highest it has ever been, a total of 9854MW from 76 wind plants, and on this day, wind generation recorded the second lowest Capacity Factor for the day in its history. The average power generation per hour for this day was 709MW, for a total power generation of 17GWH for the whole day also close to the lowest ever, considering that lower total generated power was back when the Nameplate was considerably lower than it is now. That 17GWH of total generated power from wind amounted to just 2.7% of all the generated power from every source. Look at that lower graph there, where wind power is the green colour at the bottom of the graph, and there are places where you need to squint very hard to see it rise above that zero line. At the usual time of the evening Peak of maximum power consumption, wind was just off its low point for the day, and at that time wind was supplying just 487MW of power (from that Nameplate of 9854MW) and that almost negligible total amounted to 1.7% of all the generated power from every source. As this is now Winter, both versions of solar power had long ago gone back to zero, so here we have those three renewables of choice, and all they can deliver is that 487MW, and the difference between that supply from renewables ans that Peak power consumption total was 28,548MW ….. TWENTY EIGHT THOUSAND SIX HUNDRED MEGAWATTS difference, and they tell us that renewables is the technology of the future, and that we can do without coal fired power. Oh, with wind generation so pitiful, the gap between the high and the low was just 983MW.
