Pricing event reports
AEMO prepares and publishes reports on significant price events to support market transparency, by highlighting unusual pricing outcomes in the NEM and providing information on the factors that contributed to these outcomes. Pricing event reports are brief and are posted within four business days of the event.
The reports explain:
- The factors contributing to the abnormal pricing outcomes.
- Whether outcomes were consistent with dispatch offers and power system conditions.
- The performance of pre-dispatch in forecasting the abnormal outcomes.
The reports are produced when the:
- Maximum daily spot price (trading interval price) in any region is more than $2,000/MWh (AEMO may also publish a brief report if the maximum daily spot price in any region is between $500/MWh and $2,000/MWh).
- Minimum daily spot price for any region is less than -$100/MWh.
- Maximum daily sum of Frequency Control Ancillary Services (FCAS) half hourly averaged prices:
- In Tasmania exceeds $3,000/MWh.
- In all other regions in the NEM exceeds $150/MWh.
The document Factors Contributing to Differences between Dispatch and Pre-dispatch Outcomes explains the factors that can contribute to forecasting differences between dispatch and pre-dispatch outcomes.Pricing reports September 2016
