Guest author, Josh Stabler of Energy Edge, provides a look into the ‘contagion of scarcity’ events impacting the market since mid-May 2021.
Saturday evening 25th July 2021 saw the instantaneous production from wind farms across the NEM surge past 6,000MW for the first time and set a new ‘all-time’ record that’s substantially higher than the previous record (set only a few days beforehand).

Quick notes about the winter evening peak in demand on Monday 5th July 2021

Some SMS alerts notified me of some volatile dispatch intervals this evening in mainland regions. So I took a quick look…
A short review, as it happens, on a day where renewable production reached 10,000MW in aggregate across the NEM.
Some quick reflections on a day that saw spot prices in QLD down below $0/MWh for most of the period seeing strong daylight hours, hence strong injections from rooftop PV systems.
Yesterday evening (Tue 9th June 2020) saw an example of ‘dunkelflaute’ across the NEM. It’s a phenomenon we will see increasingly as the transition progresses, so it’s something we should be seeking to understand, and address, with real world solutions and not rose coloured glasses.
