I have never been a fan of the parallel universe theory in physics but I can see that it is a real thing in climate and energy matters. Check out the contrast:
This picture will change, right now at 9.30 both Victoria and SA, the wind-leaders are importing power. This picture tells the story and shows the flow of power between the states. Those are live displays and they will change, especially when more solar power comes on line.
Sure enough at 9.50 SA is exporting as solar kicks in. But RE enthusiasts don’t want to get carried away, without coal power SA would have gone black overnight and they would be looking at a cold start if they wanted a hot breakfast. Gas is still providing almost as much local generation as wind.
At breakfast time on the east coast when there was hardly any solar, and none in SA (later sunrise), SA was importing 20% of its demand (coal power from Victoria) while gas provided more than half of the local generation. The wind was a tick above average (CP 32% compared with 29%) and of course the situation is worse when the wind is below average, which is half the time, not to mention periods of almost dead calm.
Imagine the situation in SA and Victoria when Yallourn goes off line. In Victoria at the moment the wind is almost down to drought level and coal accounts for 70% of local generation.
Tasmania, the battery of the nation, has been in deficit this morning with next to no wind.
