Collections of events that we see happening in the NEM, categorised in terms of the seasons in which they occur.
It’s taken a while to find the time – but today I’m posting this next analytical piece (Part 3) that seeks to understand what happened on Sunday 24th January 2021 with the NEM-wide SCADA Failure, which contributed to the price spike that occurred in QLD by virtue of what it did to the ‘Q>>NIL_CLWU_RGLC’ constraint equation.
A short article this afternoon to link through to the Preliminary Report published by the AEMO, looking into what happened in South Australia last Friday (12th March 2021).
Over 2,000 MW – or around 55% – of South Australia’s firm supply capacity was unavailable last Friday evening (March 12, 2021), along with virtually all of its large-scale renewable supply (a further 1,800 MW or so) but the lights…
Two months ago prices spiked in QLD on a Sunday afternoon when AEMO lost SCADA data feed. One month ago AEMO published a preliminary report. In the background we have been taking a look…
In what’s become a fairly regular occurrence the past couple months, the price spiked in QLD for a single dispatch interval as the sun was setting.
A different type of market notice today (speaking of potential curtailment of embedded generation in South Australia) points to the future … accelerated by Heywood repairs in this instance.
A shorter article – thinking more about the future, prompted by one of the factors that contributed to the price volatility seen in South Australia on Friday 12th March 2021
Prices have (finally!) subsided, so here’s an initial review of what I can see about what happened in South Australia on Friday evening 12th March 2021. Apologies for mistakes (it’s rushed, there will be some)…

Monday 22nd February 2021 saw QLD Scheduled Demand rise higher than it has on any other day so far this summer … 576MW below the all-time maximum.

Today AGL Energy announces a big impairment … with a big chunk related to long-term wind offtake agreements which AGL entered into between 2006 and 2012.
Quite a synergistic coincidence today that, at the same time as we are finalizing the release of the GSD2020, we see the AEMO publishes its Quarterly Energy Dynamics for Q4 2020.
Short article today observing higher Scheduled Demand in VIC – which appears to be in large part due to state-wide suppression of solar PV production with heavy cloud and rainfall.
Forecasts was that it would be hot across Victoria, and demand would be high, through Monday 25th January 2021. But the cool change arrived early.
Second article today, focusing on what happened late in the afternoon and into the evening in South Australia.
It was forecast it would be a hot day in the southern part of the NEM and it did not disappoint. The hot weather was one of the factors that contributed to price spikes … in Regulation FCAS, and then in QLD and later in South Australia.
