AEMO ELECTRICITY MARKET NOTICE

The MT PASA RELIABILITY_LRC results published on 21 June 2016 forecast shows low reserve conditions (LRC) in South Australia for Summer 2016-17 and Summer 2017-18. AEMO will continue to monitor the situation and take appropriate actions, if necessary.

The MT PASA results for the next 12 months are summarised at:
http://www.aemo.com.au/Electricity/Data/Forecast-Supply-and-Demand/Medium-Term-Outlook

This notice supersedes Market Notice 53965 published on 14 June 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.
