Update - Possible intervention to manage power system security in SA region
Update - Possible intervention to manage power system security in SA region
Refer AEMO Electricity Market Notice 112377
The synchronous generating units currently expected to be synchronised in SA from 0630 hrs 16/12/2023 will be inadequate to maintain a secure operating state in SA .
AEMO estimates that, in the absence of sufficient market response by 1445 hrs 15/12/2023, 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.

Issued by Australian Energy Market Operator Ltd at 1235 hrs on 15 December 2023
ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 15 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 1235 hrs on 15 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.

Possible intervention to manage power system security in South Australia (SA) Region
Possible intervention to manage power system security in South Australia (SA) Region
The synchronous generating units currently expected to be synchronised in SA from 0700 hrs 16/12/2023 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.
