AEMO ELECTRICITY MARKET NOTICE
Issued by Australian Energy Market Operator Ltd at 1535 hrs on 21 December 2024
ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 21 December 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 1535 hrs on 21 December 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.

AEMO ELECTRICITY MARKET NOTICE
Forecast Minimum System Load MSL2 condition in the VIC Region on 22/12/2024
Update to Market Notice 122341 - AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the VIC on 22/12/2024.
Minimum System Load (MSL) conditions are forecast when regional demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
- MSL1 - 1825 MW
- MSL2 - 1325 MW
- MSL3 - 825 MW
The regional demand is forecast to be below the MSL2 threshold for the following period[s]:
- From 1230 hrs 22/12/2024 to 1300 hrs 22/12/2024. Minimum regional demand is forecast to be 1314 MW at 1300 hrs.
Forecast regional demand (DEMAND50) is published in Short Term and Pre-Dispatch PASA region solution reports available on Market Data NEMWEB: https://aemo.com.au/en/energy-systems/electricity/national-electricity-market-nem/data-nem/market-data-nemweb .
