The MTPASA result published on 24 October 2024 identifies no Low Reserve Conditions.

Reliability risks in South Australia are forecast above the reliability standard due to transmission outages and reclassifications. As these outages and reclassifications are not considered as part of a reliability incident as per NER 3.9.3C, AEMO is not declaring Low Reserve Conditions at this time.

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 119186 published on 15 October 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
