Only two dispatch intervals (thus far?) of extreme pricing tonight for QLD and NSW (Wed 2nd June 2021). Here’s the first one…
solar PV; wind farm output
An unfortunately timed significant slump in output across all Wind and Large Solar plant in NSW was another of the factors contributing to the price volatility seen in NSW last week.
Third day in a row we see volatility in NSW (and QLD) … and this afternoon AEMO contracts, and then dispatches, Reserve Trader in NSW
Second day in a row the price spikes in the NSW region … higher and longer than yesterday. Low aggregate production from Wind and Large Solar across NSW today was clearly one other factor that contributed.
