RESERVE NOTICE MT PASA 22 April 2025
The MTPASA results published on 22 April 2025 identifies no Low Reserve Conditions.
MT PASA provides early information to the market on potential reliability issues, enabling the market to respond proactively and potentially avoid the need for AEMO intervention.
For further information, please refer to:
https://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data/Market-Management-System-MMS/Projected-Assessment-of-System-Adequacy
This notice supersedes Market Notice 126543 published on 15 April 2025.
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
