75574RESERVE NOTICE05/05/2020 11:53:54 AM
RESERVE NOTICE MT PASA PUBLICATION 05 May 2020
The MTPASA result published on 05 May 2020 identifies no Low Reserve Conditions.
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 75488 published on 28 April 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

Update - Possible intervention to manage power system security in South Australia (SA) Region
AEMO ELECTRICITY MARKET NOTICE
Update - Possible intervention to manage power system security in South Australia (SA) Region
Refer AEMO Electricity Market Notice 75567
The synchronous generating units expected to be synchronised in SA from 2330 hrs 05/05/2020 to 0400 hrs 06/05/2020 in Pre-dispatch published at 1630 hrs 04/05/2020 are inadequate to maintain sufficient system strength in SA and hence a secure operating state.
AEMO currently estimates that, in the absence of sufficient market response by 1500 hrs 05/05/2020, AEMO may need to intervene by issuing a direction requiring one or more SA synchronous generating unit(s) to operate or remain synchronised to maintain power system security in SA.
