Update - Possible intervention to manage power system security in SA region

Refer AEMO Electricity Market Notice 116802

The synchronous generating units currently expected to be synchronised in SA from 0900 hrs 26/05/2024 will be inadequate to maintain a secure operating state in SA .

AEMO estimates that, in the absence of sufficient market response by 1630 hrs 25/05/2024, 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.

AEMO ELECTRICITY MARKET NOTICE.

Direction - SA region 24/05/2024

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 trading intervals during the event to be intervention trading intervals, commencing from the interval ending 1605 hrs on 24/05/2024.

Intervention pricing does not apply to this AEMO intervention event.

RESERVE NOTICE MT PASA PUBLICATION 23 May 2024

The MTPASA result published on 23 May 2024 identifies no Low Reserve Conditions. Low Reserve Conditions previously identified between May 2025 and May 2026 in New South Wales are no longer forecast as unserved energy is no longer forecast above the Reliability Standard in this region and year.

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 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 116729 published on 21 May 2024.

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
