    Australian Daily Wind Power Generation Data – Monday 13 June 2022


    June 14, 2022 - PA Pundits

     

      By Anton Lang ~

      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 8587MW, and this is from the current total of 69 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 – 402MW (11.50AM)

      Daily Maximum – 1920MW (11.59PM)

      Average Wind Generation – 952MW

      Total Generated Power – 22.84GWH

      Percentage Supplied By Wind Power At The Low Point For The Day – 1.6%

      Percentage Supplied By Wind Power At Peak Power For The Day – 821MW of 29485MW – 6.45PM – 2.78% (Mid afternoon Peak with maximum rooftop solar added was 25515MW at 12.00PM)

      Average Percentage Of Overall Total Power Generation – %

      Daily Operational Capacity Factor – 11.09%

      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

      As you can see from the graphs for today, (especially, the lower one where the green colour indicating wind generation barely shows above that zero line) well this day highlights the major problem with wind generation. After almost two weeks of high wind generation with just three or low days, and with last week especially, the highest wind generation has been for a full week, well, wind generation was so low today, barely a quarter of what it was on the day before, and the average for this day of just 952MW (from a total Nameplate of 8587MW) and that very low average across the full 24 hour period gave wind generation a daily operational Capacity Factor of 11%, and that was almost twenty percent lower than the year round average. Wind hovered around its low for the day and was rising a little when the usual time for the evening Peak of maximum power consumption came around, and at that time, wind was delivering only 2.8% of all the generated power from every source. With wind generation so low for the day, that meant there was a relatively substantial difference between the low for the day and the high, and here on this day, that gap was 1518MW.
