AEMO ELECTRICITY MARKET NOTICE

Actual LOR2 South Australia Region
Refer AEMO Electricity Market Notice 54624
An actual LOR2 condition has been declared for the South Australia region from 1630 hrs until further notice during a planned outage of Heywood No1 500 kV bus in the Victoria region
If a credible contingency event occurs in this period the South Australia region would separate from the rest of the NEM and is likely to result in interruptions to power supplies.
There are sufficient capacity reserves in the South Australia region to meet electricity demand but it may not be possible to bring the required additional capacity into service in time to avoid automatic under-frequency load shedding causing power interruptions.
