[EventId:202502140905_NRM_VIC1_SA1_started] NEGRES CONSTRAINT NRM_VIC1_SA1 started operating from 14 February 2025 09:05
AEMO ELECTRICITY MARKET NOTICE
Issued by Australian Energy Market Operator Ltd at 0905 hrs on 14 February 2025
ACTUAL NEGATIVE SETTLEMENT RESIDUES - VIC to SA - 14 February 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 0905 hrs on 14 February 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.
This is an AEMO autogenerated Market Notice.
