Planned outage of Moorabool - Cressy No 1 500 kV line in the VIC region on 19/06/2025
AEMO ELECTRICITY MARKET NOTICE
The Moorabool - Cressy No 1 500 kV line in the Victoria (VIC) region is planned to be out of service from 0600 hrs to 1700 hrs on 19/06/2025.
A credible contingency event during this planned outage could cause synchronous separation of the South Australia (SA) region from the rest of the NEM.

* 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.
