Forecast Lack Of Reserve Level 2 (LOR2) in South Australia Region - 10 to 12 August 2016
Refer to AEMO Market Notice 54624
Forecast Lack Of Reserve Level 2 (LOR2) in South Australia Region - from 0700 hrs on 10/08/2016 to 1700 hrs on 12/08/2016
AEMO declares Forecast LOR2 conditions for the South Australia region during the planned outage of Heywood No.1 500 kV busbar in Victoria region, from 0700 hrs on 10/08/2016 to 1700 hrs on 12/08/2016.
On the occurrence of a credible contingency during this planned outage, South Australia region could separate from the rest of the NEM and is likely to result in interruptions to power supplies in South Australia.
There are sufficient capacity reserves in the South Australia region to meet electricity demand but following the next credible contingency it may not be possible to bring the required additional capacity into service in time to avoid automatic under-frequency load shedding causing interruptions to power supplies in South Australia.

Updates to Victorian system normal stability constraint equations
The Victorian system normal constraint equations that determine Victorian export limits based on transient stability and voltage stability at Heywood for Victoria to South Australia flows will be updated to a revised formulation on 25 July 2016 after 1330 hrs. This revised formulation models the effects of higher flows on Victoria to SA on Heywood and the new series capacitors at Black Range.
The changes are to the following constraint equations :
V::N_NIL_V1
V::N_NIL_V2
V::N_NIL_Q1
V::N_NIL_Q2
V::N_NIL_S1
V::N_NIL_S2
V::N_NIL_SD
