Issued by Australian Energy Market Operator Ltd at 0830 hrs on 12 November 2024

ACTUAL NEGATIVE SETTLEMENT RESIDUES - QLD to NSW - 12 November 2024.

Electricity Market outcomes have resulted in the accumulation of negative settlement residues that have exceeded the allowable negative residue threshold for the QLD to NSW directional interconnector.

The negative residue constraint set NRM_QLD1_NSW1 commenced operating from 0830 hrs on 12 November 2024.

This constraint set contains an equation with the following interconnectors on the LHS:
N-Q-MNSP1
NSW1-QLD1

The RHS of the constraint equation may be adjusted to manage residues.
