The Australian Energy Regulator (AER) is required to publish a report on significant price outcomes in the National Electricity Market (NEM).
This is the first report published under the revised Significant price reporting guidelines (Guideline) outcome criteria. Instead of the fixed $5,000/MWh price to determine a significant price outcome, the AER will now take a principles-based approach to select the significant price outcomes each quarter and report on a minimum of four days.
This report includes events that occurred in South Australia and Tasmania during January to March 2026 on:
- 12 January
- 26 - 27 January
- 17 February
- 3 March
The AER must consider whether the following factors contributed to the significant price outcomes:
- available capacity
- network availability
- offer, bidding and rebidding behaviour in respect of the relevant market.
The AER may consider the following matters:
- broader and ongoing market trends that may be contributing to the significant price outcomes
- any events and behaviours that may be detrimental to effective competition or efficient market operation
- any other matter which the AER considers relevant.
