Issued by Australian Energy Market Operator Ltd at 1435 hrs on 30 December 2024
ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 30 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 1435 hrs on 30 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.

Forecast Minimum System Load MSL1 condition in the VIC region on 01/01/2025
AEMO ELECTRICITY MARKET NOTICE
Update to Market Notice 122490 - AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the VIC region on 01/01/2025.
Minimum System Load (MSL) conditions are forecast when regional demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
MSL1 - 1560 MW
MSL2 - 1060 MW
MSL3 - 560 MW
The regional demand is forecast to be below the MSL1 threshold for the following period:
From 1030 hrs to 1430 hrs 01/01/2025. Minimum regional demand is forecast to be 1264 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.
