Possible intervention to manage power system security in South Australia (SA) Region
AEMO ELECTRICITY MARKET NOTICE
Possible intervention to manage power system security in South Australia (SA) Region
The synchronous generating units expected to be synchronised in SA from 2300 hrs 22/06/2021 to 1700 hrs 23/06/2021 in Pre-dispatch published at 1430 hrs 22/06/2021 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 1700 hrs 22/06/2021, 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.

RESERVE NOTICE MT PASA PUBLICATION 22 June 2021
The MTPASA result published on 22 June 2021 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 87204 published on 15th June 2021.
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
