AEMO ELECTRICITY MARKET NOTICE
Direction - SA Region - 14/09/2021
In accordance with section 116 of the National Electricity Law, AEMO has issued a direction to a participant in the SA region. For the purposes of the National Electricity Rules this is a direction under clause 4.8.9(a).
The direction was necessary to maintain the power system in a secure operating state.
AEMO may issue or revoke additional directions in order to meet the current requirement, unless sufficient market response is provided. A further market notice will be issued when all directions related to this requirement have been cancelled.
The issue of the direction commences an AEMO intervention event. AEMO declares all dispatch intervals during the event to be intervention dispatch intervals, commencing from the interval ending 1635 hrs on 14/09/2021.

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 currently expected to be synchronised in SA from 0930 hrs 15/09/2021 to 1500 hrs 15/09/2021 will be inadequate to maintain sufficient system strength in SA and hence a secure operating state.
AEMO estimates that, in the absence of sufficient market response by 1630 hrs 14/09/2021, 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.

90467RESERVE NOTICE14/09/2021 11:37:46 AM
RESERVE NOTICE MT PASA PUBLICATION 14 September 2021
The MTPASA result published on 14 September 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 90261 published on 7 September 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
https://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Planning-and-forecasting/Reliability-Standard-Implementation-Guidelines
