AEMO ELECTRICITY MARKET NOTICE
Issued by Australian Energy Market Operator Ltd at 1435 hrs on 19 January 2024
ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 19 January 2024.
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 1435 hrs on 19 January 2024.
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.

Possible intervention to manage power system security in South Australia (SA) Region
AEMO ELECTRICITY MARKET NOTICE
Possible intervention to manage power system security in South Australia (SA) Region
The synchronous generating units currently expected to be synchronised in SA from 0130 hrs 20/01/2024 will be inadequate to maintain sufficient system strength in SA and hence a secure operating state.
AEMO may need to intervene by issuing a direction requiring one or more SA synchronous generating unit(s) to operate or remain synchronised to maintain power system security in SA.
