Update to system normal constraint equation in NSW for transient voltage stability in south-west NSW
AEMO ELECTRICITY MARKET NOTICE
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.
For further details on these constraint equation please contact ben.blake@aemo.com.au

Planned outage of Tailem Bend - South East 275 kV transmission line in the South Australia region beginning on 20/09/2024
AEMO ELECTRICITY MARKET NOTICE
The Tailem Bend - South East No 1 275 kV line in the South Australian (SA) region is planned to be out of service from 2100 hrs on 20/09/2024 to 0530 hrs on 21/09/2024.
A credible contingency event during this planned outage could cause synchronous separation of the SA region from the rest of the NEM.
During this planned outage:
- Power transfer will be restricted across the VIC - SA interconnector (Heywood interconnector); and
- Post contingent FCAS will be sourced within SA following Separation event.
Refer AEMO Network Outage Schedule (NOS) for further details.
