Pricing Event Reports

AEMO prepares and publishes reports on significant price events. The publishing of the reports supports AEMO’s commitment to market transparency by highlighting unusual pricing outcomes in the NEM, and by providing information on the factors that contributed to these outcomes. The pricing event reports are brief and posted within 4 business days of the event.

The reports are produced when the:

  • maximum daily spot price (trading interval price) in any region is more than $500/MWh;
  • minimum daily spot price for any region is less than -$100/MWh;
  • maximum daily sum of Frequency Control Ancillary Services half hourly averaged prices
    ­      - in Tasmania exceeds $3,000/MWh
    ­      - in all other regions in the NEM exceeds $70/MWh

The reports also explain:

  • the factors contributing to the abnormal pricing outcomes
  • whether outcomes were consistent with dispatch offers and power system conditions; and
  • the performance of Pre-dispatch in forecasting the abnormal outcomes
     

The document Factors Contributing to Differences between Dispatch and Pre-dispatch Outcomes explains the various factors that can contribute to forecasting differences between Dispatch and Pre-dispatch outcomes.
