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.

Sunday 24th November 2019

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 6702MW, and this is from the current total of 55 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 – 503MW (11.15AM)

Daily Maximum – 1437MW (6.10PM)

Average Wind Generation – 995MW

Total Generated Power – 23.88GWH

Percentage Supplied By Wind Power At The Low Point For The Day – 2.20%

Percentage Supplied By Wind Power At Peak Power For The Day – 1079MW of 23300MW – 6.45PMPM – 4.63%

Average Percentage Of Overall Total Power Generation – 4.7%

Daily Operational Capacity Factor – 14.85%

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.

Notes

  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.

Weekly UPDATE

Generated wind power total as a Percentage of overall total generated power from every source for this last week – 7.4%

Generated wind power total as a Percentage of overall total generated power from every source for the last year (52 weeks) – 8.1%

Capacity Factor for wind power generation for the last week (7 days) – 25.19%

Capacity Factor for wind power generation for the last year (52 weeks) – 29.50%

Capacity Factor for wind power generation for the longer term (60 Weeks) – 29.59%

Comments For This Day

There is one important thing I would like to point out here. Note that the peak power consumption on this day (the Sunday, on the weekend) is back at the evening time of 6.45, when for every weekday, that peak was as it usually is in the warmer Months, closer to Midday and the early afternoon. At that same early afternoon time on this Sunday, total power generation, which equates almost exactly to actual power consumption was only 22000MW. This is on a Sunday, when all the schools, all the industries and nearly all places of work are closed. The vast proportion of the population are at home on this day, and not at work or at school. On those working week days, just for this week alone the total power generation/consumption at that same time (early afternoon) ranged between 26000MW and (almost) 31000MW. That’s a difference of between 4000MW and 7000MW. On this day, (Sunday) with residential power consumption at its highest because everyone is at home, power consumption is at its lowest for the week. During week days, when that residential consumption is actually a lot lower, overall power consumption is a huge amount higher, and this just proves again that power consumption is largest in the NON residential sector.

Wind power was again low, not much better than half the year round average, and on the day of the lowest power consumption, wind power only delivered 4.7% of all the power needed to run the Country. With wind power having a lower than average week, note that for those weekly figures, wind power only delivered 7.4% of the power.

The weekly operational Capacity Factor for wind power only came in at a little over 25% for the week. That slightly lowered the figure for both the year and longer term average for that Capacity Factor, still just below that 30% figure I have always used.
