[EventId:202501021315_NRM_NSW1_VIC1_started] NEGRES CONSTRAINT NRM_NSW1_VIC1 started operating from 02 January 2025 13:15
Issued by Australian Energy Market Operator Ltd at 1315 hrs on 2 January 2025
ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 2 January 2025.
Electricity Market outcomes have resulted in the accumulation of negative settlement residues that have exceeded the allowable negative residue threshold for the NSW to VIC directional interconnector.
The negative residue constraint set NRM_NSW1_VIC1 commenced operating from 1315 hrs on 2 January 2025.
This constraint set contains an equation with the following interconnectors on the LHS:
VIC1-NSW1
The RHS of the constraint equation may be adjusted to manage residues.
This is an AEMO autogenerated Market Notice.

Cancellation of a Non-Credible Contingency Event: Guybal Munjan - Chalumbin 857 275kV line line and Guybal Munjan - Chalumbin 858 275kV line line in QLD1 due to Lightning.
Cancellation of reclassification of a Non-Credible Contingency Event as a Credible Contingency Event due to Lightning. AEMO considers the simultaneous trip of the following circuits is no longer reasonably possible. There is no longer any lightning activity in the vicinity of the following lines. Accordingly its classification has reverted to a non-credible contingency event.
Region: QLD1
Lines: Guybal Munjan - Chalumbin 857 275kV line and Guybal Munjan - Chalumbin 858 275kV line

Cancellation: Reclassification of non-credible contingency event due to existence of widespread abnormal condition/s - NEM regions.
AEMO considers the occurrence of a non-credible contingency event due to the widespread abnormal conditions advised in AEMO Electricity Market Notice 122691 (Severe Space Weather) is no longer reasonably possible and accordingly its classification has reverted to non-credible.
