If you like a hot dinner, or hot coffee on the way to work, don’t depend on wind and solar power. This evening the sun was gone across SE Australia by dinnertime and the wind was down to 2% of the power supply with the windmills delivering 7% of their capacity. I define 10% and under as a wind drought.
This was the story told by the NemWatch widget – live display. Tell your friends and relations to check the widget morning and evening to see how much or how little green for wind is visible.
Below is a display from the AEMO data dashboard. This is the fuel mix and another display, the dispatch overview, shows the flows between the states and the prices, all updated at five-minute intervals.
The chart below from Aneroid Energy indicates the state of the wind supply over 24 hours, expressed as a % of the installed capacity.
The whole of the NEM (the SE Australian grid) was below 10% after breakfast, including NSW where the wind was up to average yesterday and went slowly downhill today.
Victoria has been in drought since breakfast.
SA and Tasmania have been in drought since noon yesterday, and Tasmania hit zero just before lunch and registered -1.4% all afternoon. At 8 it was up to 3%.
