The rule change is officially labelled as ‘temporary’ and has an end date of June 30th, 2025. During this period, it is expected that longer-term changes to the APC and associated mechanisms will be considered by the AEMC’s Reliability Panel.
Dan is a Market Analyst, who joined Global-Roam in June 2013.
He departed (and returned) for a couple of brief stints overseas, before rejoining the team permanently in late 2019. Alongside his work at Global-Roam, he has undertaken short-term contract roles as an analyst and researcher in various areas of the energy sector. Dan graduated from the Master of Sustainable Energy program at the University of Queensland in 2024.
Wednesday 28th January saw demand across the NEM jump to unprecedented levels, setting a new record of 34,843MW at 16:00 NEM time. On Thursday 29th January, we saw the demand increase still further, leading to prices that stayed high for much of the day (to the point where the Cumulative Price Threshold was reached in VIC and SA and price caps were imposed), and a relatively small amount of involuntary load shedding occurring in VIC and SA.
It’s not a surprise to me to see that someone (the AER in this case) has released an Issues Paper canvassing options for changing the way Semi-Scheduled generators interact with the dispatch process. Not a surprise, as our prior analysis suggests the current approach is not sustainable or scalable.
Following on from Friday’s article (which considered the AER Issues Paper) this article delves into more detail of those extremes of ‘Aggregate Raw Off-Target’ across all Semi-Scheduled units that have been recorded over the past 10 years. There’s a clear clustering of cases in 2019 – what does it mean?
Thanks for covering this Dan. Just noting that the Reliability Panel has completed the 2022 Reliability Standard and Settings Review and recommended an APC of $500/MWh for the period 1 July 2025 to 30 June 2028 (along with recommended changes to the MPC and CPT).
The Reliability Panel will now need to submit a rule change request to the AEMC in order to implement the recommended changes to the settings. The AEMC would consider any proposed changes through the usual rule change process, allowing further opportunities for stakeholder input and consultation.
