Now making it 5 out of the past 6 years, we return to the analysis of electricity (spot and futures) pricing patterns for Q2 periods across the NEM regions … and also in Western Australia. We see a number of ways in which Q2 2021 was ‘anything but boring’!
It was volatile this morning well past that’s become ‘normal’ and the volatility has returned (as I expected it would) this evening. Here’s the snapshot of the 17:20 dispatch interval…
Spot prices spiked across mainland regions this evening – firstly at 17:55 (above $1,000/MWh). and then at 18:00 (up towards $15,000/MWh). Here’s a first look.
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…
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.
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)…
The price has spiked in South Australia this evening (Fri 12th March 2021). Here’s Part 1…
A longer-term trend of the incidence of negative prices across each region of the NEM … and, most interestingly, the pattern by time of day.

Guest author Allan O’Neil puts together an in-depth explainer about system strength and looks at the current approach to system strength management in South Australia, its impacts and the imminent installation of synchronous condensers on the SA grid.
Several conversations this week prompted me to update the long-term view of how spot prices have trended over time (in particular because average prices in 2020 were quite different than recent years).
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.
Following several different warnings of high temperatures forecast for the lead-in to Tuesday 26th January 2021 (whatever you want to call that day) I’ve taken a quick look at what it’s currently forecast to mean for the NEM…
Some brief notes about the impact that South Australia’s ‘Stay at Home’ order might have on demand in the region.
On Thursday 22nd October, the AEMO also released a short document titled ‘Operational management of low demand in South Australia’.

Hot on the heels of a new record low point for Scheduled Demand (a week ago) in VIC, today sees Scheduled Demand in SA plunge to 315MW in the 11:50 dispatch interval on Sunday 13th September 2020.
