76456RESERVE NOTICE28/07/2020 01:13:25 PM

RESERVE NOTICE MT PASA PUBLICATION 28 July 2020

The MTPASA result published on 28 July 2020 identifies no Low Reserve Conditions. This week's MTPASA includes updates for new committed generation found in the most recently published Generation Information page. This includes the addition of scheduled capacity from Temporary Generation South.

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

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 76392 published on 21 July 2020.

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
