Possible intervention to manage power system security in SA Region
Possible intervention to manage power system security in SA Region
The synchronous generating units currently expected to be synchronised in SA from 0030 hrs 23/02/2024 will be inadequate to maintain a secure operating state in SA.
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.

Direction - SA region 21/02/2024
Direction - SA region 21/02/2024
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 1635 hrs on 21/02/2024.
Intervention pricing does not apply to this AEMO intervention event.

The synchronous generating units currently expected to be synchronised in SA from 0700 hrs 22/02/2024 will be inadequate to maintain a secure operating state in SA .
AEMO estimates that, in the absence of sufficient market response by 1630 hrs 21/02/2024, 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.

Update to system strength constraints in North Queensland
Refer to market notice 110677
AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
Due to commissioning of new feeder 8905 (H13 Ross - H39 Woree) 275kV line in Far North Queensland, the system normal system strength equations for low North Queensland demands and all Karreya stations out of service conditions have been revised.
A revision to the constraint equations will be implemented at 1400 hrs on Tuesday 20th February 2024.
The new system strength combinations have now published in a limits advice document on AEMO's website. For more information refer to the new limits advice: https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/system-operations/congestion-information-resource/limits-advice
This advice contains all the combinations for Queensland for system normal cases.
Below constraint equations in the Q-NIL set will be modified:
- Q_NIL_STRGTH_KBWF
- Q_NIL_STRGTH_KBWF_I
- Q_NIL_STRGTH_HAUSF
- Q_NIL_STRGTH_HAUSF_I
- Q_NIL_STRGTH_MEWF
