Actual LOR2 South Australia Region - 8/11/2016
AEMO ELECTRICITY MARKET NOTICE
Actual LOR2 South Australia Region - 8/11/2016
An actual LOR2 condition has been declared for the South Australia region from 0600 hrs and is forecast to continue until further notice during the following planned outages detailed below:
[1] Heywood No.2 500 kV busbar from 0600 hrs 08/11/2016 to 1600 hrs 09/11/2016.
[2] Heywood to Mortlake 500 kV transmission line from 0600 hrs to 1600 hrs daily on 08/11/2016 and 09/11/2016.
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.

Change to FCAS Regulation constraint equations for managing time error
AEMO ELECTRICITY MARKET NOTICE
Change to FCAS Regulation constraint equations for managing time error
AEMO is changing the way the FCAS constraint equations work for automatically increasing the regulation when the time error exceeds 1.5s in the Mainland. Currently the regulation is required from all NEM regions when there is a Mainland (NSW, Qld, SA and Victoria) time error.
The change to be made is to set the FCAS regulation requirements for Mainland regions only when there is a Mainland time error exceedance.
The FCAS requirements from all NEM regions of 120 MW lower regulation and 130 MW raise regulation has not changed.
The calculation for the regulation is detailed in SO_OP3715, section 19.
This change will take effect at 1700 hrs on 25 October 2016.

AEMO ELECTRICITY MARKET NOTICE
Actual LOR2 South Australia Region - Thursday, 20 October 2016
An actual LOR2 condition has been declared for the South Australia region from 2050 hrs and is forecast to continue until further notice during a planned outage of Heywood to South East No.2 275 kV transmission line between the Victoria and South Australia regions.
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.
