[EventId:202312081450_NRM_NSW1_VIC1_started] NEGRES CONSTRAINT NRM_NSW1_VIC1 started operating from 08 December 2023 14:50
Issued by Australian Energy Market Operator Ltd at 1450 hrs on 8 December 2023
ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 8 December 2023.
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 1450 hrs on 8 December 2023.
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.
Possible intervention to manage power system security in SA Region
Possible intervention to manage power system security in SA Region
The synchronous generating units currently expected to be synchronised in SA from 0930 hrs 09/12/2023 will be inadequate to maintain a secure operating state in SA.
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.
