Actual LOR2 South Australia Region - 06 Sept 2016

AEMO ELECTRICITY MARKET NOTICE

Actual LOR2 South Australia Region - 06 Sept 2016

Refer AEMO Electricity Market Notice 54686

An Actual LOR2 condition is declared for the South Australia region from 0710 hrs until further notice due to the planned outage of the Heywood No.2 500 kV busbar.

If a credible contingency event occurs during 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.
