ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 29 September 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 1820 hrs on 29 September 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

Update to Market Notice 118421.

AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the Victorian region from 1030 hrs to 1430 hrs 28/09/2024.

Minimum regional demand is forecast to be 1420 MW at 1200 hrs, and the advisory threshold is:
- MSL1 - 1865 MW
- MSL2 - 1365 MW
- MSL3 - 865 MW

MSL events are forecast when forecast regional demand is less than the relevant MSL threshold. The forecast regional demand is below the MSL1 threshold.

Refer to NEM Data Dashboard to monitor demand levels: https://aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem

AEMO is seeking a market response.

An insufficient market response may require AEMO to take action or intervene to maintain power system security in Victoria. This may result in action such as the direction of scheduled production units, curtailment of non-scheduled production units, and/or a direction to maintain regional demand above required MSL threshold, in both Victoria and South Australia.
