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…
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.
Today (Sunday 14th February 2021) ‘Scheduled Demand’ dropped down again in South Australia – almost setting a new record for ‘lowest point since the start of the NEM (excl System Black)’
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’.
Records continue to tumble in the off-season, with the rise of rooftop PV. Both South Australia and Whole-of-NEM hit new low points Sun 11th October 2020.
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.
Out of curiosity, and driven by questions received from several people, I’ve invested a bit of time today to delve further into the record low level of Scheduled Demand seen in the Victorian region (and perhaps also across the whole of the NEM) on Saturday 29th August 2020.
AEMO also published something else today which (whilst not as publicised as the ESOO) will be of keen interest to many stakeholders in South Australia…
This 8th case study in this series presents tabular results for all Semi-Scheduled DUIDs which were operational at the time of the SA System Black event.
After publishing three Case Studies on Saturday, this 4th Case Study in a long series is much more complex – with 8 different Semi-Scheduled Wind Farm units across VIC and SA exhibiting significant deviations from Target. This Case study looks at April 2016, which is also 3 years after the first 3 case studies.
