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.
