Update this evening, at the peak of demand between 6 and 7 and the sun off duty. The wind edged up to 10% of installed capacity to provide 740MW that was 2.5% of demand. Coal and gas kicked in 82% and hydro 15%.
At 9pm wind has improved to reach 3.6% of demand but Victoria is still in the red, draining 5.7MW from the grid, not a huge amount of power I suppose as long as the coal clunkers keep going to provide it.
Interesting wind today, after roaring winds on the weekend and into Monday a decline started on Monday and after a meandering downhill run the supply bottomed at 3pm this afternoon at 3.2% of installed capacity and 250MW. That was 1% of the demand, surely close to a record!
In Victoria, the new wind leader for installed capacity (2.77GW) the contribution was negative after 12.15 (-5.6MW at 2pm) and it was still negative at 7pm.
Tasmania, the battery of the nation, was being charged at 2.00 but has since turned around and is delivering to Victoria that is the usual state of affairs.
Trouble in the solar paradise of Queensland as well.
As Paul McArdle of WattClarity says: “the NEM* is becoming increasingly dependent on the weather“
Saturday week ago in Queensland was cold enough to break records. Brisbane “only” made it up to 17.9C (64F). It hasn’t been that cold there in May for 40 years. At the same time a band of cloud covered the populated slice of the state.
The cloud cover meant all the large solar “farms” in Queensland — with a total rated capacity of 1.7GW — produced only 79MW as an aggregate average daily output.
