2024 Consultation on Forecasting Accuracy Report Methodology

AEMO is consulting on the methodology for its Forecasting Accuracy Report

This is the one used for the assessment of AEMO’s longer-term electricity demand and supply forecasts.

The forecasts are used in many reliability and planning processes, including:

  • Medium Term Projected Assessment of System Adequacy (MT PASA),
  • The Electricity Statement of Opportunities (ESOO) and the associated reliability forecast used for the Retailer Reliability Obligation (RRO), and
  • The Integrated System Plan (ISP).

This twitter (X) post alerted us to the current status of the consultation following record demand in QLD, lack of reserve projections in some regions and even a projected possibility of load shedding requiring the use of the Reliability and Emergency Reserve Trader “RERT” to be raised.

The AER’s forecasting best practice guidelines require AEMO to consult on this methodology at least once every 4 years. This means the next opportunity for material revisions might not be until 2028. The last consultation was in 2020.
