AEMO ELECTRICITY MARKET NOTICE
Issued by Australian Energy Market Operator Ltd at 1110 hrs on 28 September 2021
ACTUAL NEGATIVE SETTLEMENT RESIDUES - QLD to NSW - 28 September 2021.
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 1110 hrs on 28 September 2021.
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.
