The MTPASA result published on 19 November 2024 identifies Low Reserve Conditions as annual unserved energy exceeds the Reliability Standard between:
-- November 2024 - November 2025 in New South Wales and Victoria

AEMO declares Low Reserve Conditions in accordance with clause 4.8.4 of the National Electricity Rules (NER) for the following region(s) and periods:
-- November 2024 and January - March 2025 in Victoria
-- November 2024 - February 2025 in New South Wales
when forecast demand exceeds supply under some circumstances.

Please note MTPASA informs the market of potential reliability issues to allow the market to respond in the first instance, potentially avoiding the need for any AEMO intervention.

For further information, please refer to:

This notice supersedes Market Notice 120282 published on 12 November 2024.


Background

As part of a broader process of implementing the reliability standard, AEMO runs the Medium Term Projected Assessment of System Adequacy (MTPASA) process weekly to forecast expected unserved energy levels over a two year period. If the expected annual unserved energy exceeds the maximum level specified by the Reliability Standard, a Low Reserve Condition is identified.

For more information about how AEMO implements the reliability standard, please view the Reliability Standard Implementation Guidelines (RSIG) available on AEMO's website at https://www.aemo.com.au/Electricity/National
