AEMO ELECTRICITY MARKET NOTICE
Issued by Australian Energy Market Operator Ltd at 1310 hrs on 8 March 2025
ACTUAL NEGATIVE SETTLEMENT RESIDUES - VIC to SA - 8 March 2025.
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 1310 hrs on 8 March 2025.
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.
