ACTUAL NEGATIVE SETTLEMENT RESIDUES - SA to VIC - 7 July 2016.
Electricity Market outcomes have resulted in the accumulation of negative settlement residues that have exceeded the allowable negative residue threshold for the SA to VIC directional interconnector.
The negative residue constraint set NRM_SA1_VIC1 commenced operating from 0905 hrs on 7 July 2016.
This constraint set contains an equation with the following interconnectors on the LHS:
V-S-MNSP1
V-SA
The RHS of the constraint equation may be adjusted to manage residues.
