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 7728MW, and this is from the current total of 64 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 – 413MW (11.55PM)

Daily Maximum – 1252MW (12.35AM)

Average Wind Generation – 800MW

Total Generated Power – 19.20GWH

Percentage Supplied By Wind Power At The Low Point For The Day – 1.8%

Percentage Supplied By Wind Power At Peak Power For The Day – 571MW of 28600MW – 6.20PM – 2.00%

Average Percentage Of Overall Total Power Generation – 2.8%

Daily Operational Capacity Factor – 10.35%

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.

Comments For This Day

Again, as you can plainly see on that uppermost graph, after the large falling away of wind power generation of the day before, it just continued its slide again on this day, dropping progressively across the day to its minimum of just 400MW. That 400MW is from a Nameplate of 7728MW, so that’s 7300MW of wind towers (around 4200 individual wind towers) standing there in their fields, totally motionless, doing nothing, generating nothing, contributing nothing, delivering no power at all to the grid, 7300MW. This is a horrendous waste of money. Not only are they not contributing, but the actual thing they were supposed to replace, fossil fuelled power plants, are in fact actually having to make up that power they are not delivering, so on the part of wind power, it is in fact a DOUBLE failure.

That average for the day of just 800MW is close to the lowest wind generation average there has been here in Australia. That daily average gave wind generation a daily operational Capacity Factor of just 10.35%, so, averaged across the whole day, only one in ten of those wind towers was actually delivering any power, borne out by the fact that wind generation made up only 2.8% of power delivery across the whole day, 800MW from a total average requirement across the day of 28,600MW. At the most critical point for power delivery across the day, the evening peak power time at around 6PM to 6.30PM, wind generation delivered only 2% of what was required.

The day before this one I included the graph for ALL the wind power in the State of Victoria, and that showed that for 12 long hours all those 23 wind plants in that State with a Nameplate of 2774MW delivered ZERO power to the grid in that State, and in fact sucked power from the grid for those 12 hours.

Well on this day, the following day, it was the turn of the State of South Australia to have zero power for twelve hours, and that is shown with the graph at right (again, click on the image to open it on a new page and at a larger size so you can better see the detail) and wind generation rolled along the zero line for all the time from Midday onwards. The small time it did poke its head above that zero line, (just) well that cancelled out all the power they too were sucking FROM the grid. This State has a Nameplate for wind of 2142MW from its total of 22 wind plants, and around 1200 individual wind towers, all of them motionless. It fell away from its already low of 470MW at 2AM, dropping like a stone to zero at Midday.

And with that large high just hovering over that area where all those wind plants are located, the same will apply for tomorrow as well, low to zero power generation from a source of power that has cost an astronomical amount of money. And they want to keep building more of them, and shutting off the only power supply that actually delivers power when they can’t.
