ACTUAL NEGATIVE SETTLEMENT RESIDUES - NSW to VIC - 2 October 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 1110 hrs on 2 October 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.

Update to system normal constraint equation in NSW for transient voltage stability in south-west NSW
Refer to market notice 92840.
Transgrid has advised AEMO of an update to the transient voltage stability limit in south-west NSW for loss of Darlington Point to Wagga (63) 330 kV line. The limit will include terms for the Darlington Point and Riverina BESS.
The following constraint equation will be updated with the above changes at 1100 hrs Friday 20th September 2024.
N::N_NIL_63
For full details on the formulation, the new constraint equation has now been loaded into AEMO's pre-production systems.

At 1446 hrs the Gordon - Chapel St No 1 and No 2 220 kV lines were returned to service.
This non-credible contingency event was caused by lightning. There is no longer any lightning activity in the vicinity of the following lines. Accordingly its classification has reverted to a non-credible contingency event.
