Also last week, AEMO informed the market of the availability of a report outlining 18 discrete incidents, over a period of just under 3 years, that included SCADA failure in some way. The report also discusses what has been done to rectify.
Here’s where to find AEMO’s preliminary report on the loss of SCADA on 22nd April 2023 in Victoria that led to that region being suspended for more than 24 hours.
In an event (that seems) similar to 17th March 2023, a glitch in SCADA leads to the suspension of the market in the Victorian region on Saturday afternoon/evening 22nd April 2023.
On 6th April 2023 the AEMO published this preliminary report into the brief market suspension that occurred in NSW on 17th March 2023.

A short back-dated article, to link in AEMO’s final report on this incident.
It’s now seven months since the SCADA outage on Sunday 24th January 2021 – and we’re finally able to complete and publish this (quite long) article exploring some of the implications for units on the LHS of the ‘Q>>NIL_CLWU_RGLC’ constraint equation
More time has elapsed since ‘Part 3’ on 24th March – today I’m posting a shorter piece (Part 4) that explains how RHS of the ‘Q>>NIL_CLWU_RGLC’ constraint equation drove down output and led to the price spike on Sunday 24th January 2021.
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.
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…
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.
