Apart from a distraction early this morning, I’ve invested some hours today in review of the 2023 ESOO. Here’s 7 initial observations that jumped out at me.
Here’s my view on whether Figure 2 should have preceded Figure 1 (with respect to projections of unserved energy … USE) in the 2023 ESOO.
One observation about the 2023 ESOO is that EFOR (equivalent forced outage rate) for coal and large gas units is a large and growing challenge.
One observation about the 2023 ESOO is that AEMO is has highlighted the set of constraints modelled is only ‘System Normal’.
One observation about the 2023 ESOO is that AEMO is now modelling (more accurately) the high temperature degradation on wind farm performance.

An article today referencing the VEPC paper ‘No longer lost in transmission’ (about extended VNI-West, and the authors proposed alternative ‘Plan B’) and the AEMO’s initial response.
After having had an extended break abroad, the coverage from last week’s AEW event provided a unique opportunity to check back in with the energy market from an outsider’s perspective.
Worth a short note that (on the first official day of winter … though in temperature terms it started some weeks ago) they have published a Media Release ‘AEMO forecasts improved winter 2023 for Australia’s energy system, risks remain’ that…
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.
A short article to note that the AEMO released it’s QED for Q1 2023 this morning, and a list of the early media coverage.
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.

Our fourth article looking forward to this Friday afternoon (3rd February 2023) in the Queensland region, where successive AEMO STPASA forecast data is showing considerable variability about what peak demand might be for the QLD region (it *might*, if predictions turn into reality, smash the prior all-time record). Dan Lee looks into how the demand forecast has been evolving and what to watch for this Friday afternoon.
