RESERVE NOTICE MT PASA PUBLICATION 13 SEPTEMBER 2016
AEMO ELECTRICITY MARKET NOTICE
The MT PASA RELIABILITY_LRC results published on 13 September 2016 forecast shows low reserve conditions (LRC) in South Australia for Summer 2016-17 and Summer 2017-18. The results also shows LRC in Queensland for Summer 2017-18. AEMO will continue to monitor the situation and take appropriate actions, if necessary.
The MT PASA results for the next 24 months are summarised at:
http://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data-dashboard#medium-term-outlook
This notice supersedes Market Notice 54854 published on 06 September 2016.
Please find the following information on some key inputs used in MT PASA:
Static minimum reserve levels (MRLs) have been specified for QLD, NSW and TAS regions as follows:
QLD: 913 MW
NSW: -1564 MW
TAS: 144 MW
The following optimum shared minimum reserve levels between Victoria and South Australia regions have been specified:
VIC Reserve >= 205.00
5.88 * VIC Reserve + SA Reserve >= 1237.88
1.33 * VIC Reserve + SA Reserve >= 228.00
0.43 * VIC Reserve + SA Reserve >= -40.53
0.23 * VIC Reserve + SA Reserve >= -147.55
SA Reserve >= -368.00
In order to remain consistent with the calculation of the minimum reserve levels, the following interconnector headroom constraints (net import/export limit constraints) have also been applied in MT PASA:
QLD: 0 MW of maximum net import into QLD.
NSW: 330 MW of minimum net export from NSW.
VIC: 940MW of maximum net import into VIC.
SA: 0 MW of maximum net import into SA.
Demand Side Participation included in MT PASA are:
Summer: QLD 147.5 MW, NSW 248.5 MW, VIC 141.8 MW, SA 120.2 MW and TAS 43 MW

Actual LOR2 South Australia Region - 13 Sept 16
AEMO ELECTRICITY MARKET NOTICE
Actual LOR2 South Australia Region - 13 Sept 16
Refer AEMO Electricity Market Notice 54865
An actual LOR2 condition has been declared for the South Australia region from 830 hrs and is forecast to continue until 1700 hrs during a planned outage of Moorabool - Mortlake 500 kV line 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.

Planned outage of Heywood to South East No.1 275 kV line in South Australia and Victoria regions from 11/10/2016 0700 hrs to 13/10/2016 1700 hrs
AEMO ELECTRICITY MARKET NOTICE.
This market notice is FOR INFORMATION ONLY.
The Heywood to South East No.1 275 kV line in South Australia and Victoria regions is planned out of service from 0700 hrs on 11 October 2016 to 1700 hrs on 13 October 2016. During this outage, Heywood 500/275 kV M1 transformer will be off-loaded
During this outage, a credible contingency can separate South Australia region from the rest of the NEM.
Under these circumstances, 35 MW of Raise and Lower regulation FCAS will be sourced from South Australia for the duration of this outage. In addition, consistent with AEMO existing procedures, adequate contingency FCAS lower requirements will also be sourced from South Australia at times when power transfer is from South Australia to Victoria.
The following constraint sets have been invoked for this outage:
F-I-HYSE (includes F-S_LREG_0035 and F-S_RREG_0035)
I-HYSE
S-X_BC_CP
V-HYTX_M12
Refer AEMO Network Outage Schedule (NOS) for further details.
AEMO will continue monitoring this proposed outage and will update the Market accordingly.
