Issued by Australian Energy Market Operator Ltd at 0955 hrs on 21 February 2024
ACTUAL NEGATIVE SETTLEMENT RESIDUES - VIC to SA - 21 February 2024.
Electricity Market outcomes have resulted in the accumulation of negative settlement residues that have exceeded the allowable negative residue threshold for the VIC to SA directional interconnector.
The negative residue constraint set NRM_VIC1_SA1 commenced operating from 0955 hrs on 21 February 2024.
This constraint set contains an equation with the following interconnectors on the LHS:
V-S-MNSP1
V-SA
The RHS of the constraint equation may be adjusted to manage residues.

Update to system strength constraints in North Queensland
AEMO ELECTRICITY MARKET NOTICE
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
