Forecast Minimum System Load (MSL1) condition in the VIC region on 03/11/2024
AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the VIC region on 03/11/2024.
Minimum System Load (MSL) conditions are forecast when regional demand is less than the relevant MSL threshold. The advisory MSL thresholds are:
o MSL1 - 1770 MW
o MSL2 - 1270 MW
o MSL3 - 770 MW
The regional demand is forecast to be below the MSL1 threshold for the following period:
From 1100 hrs to 1400 hrs 03/11/2024. Minimum regional demand is forecast to be 1424 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 .

ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 2 November 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 1220 hrs on 2 November 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.
