Exclusions majeure events network constraints that are invoked to manage the reclassification of non-credible contingency events to credible contingency events as per sections 4.2.3A and 4.2.3B of the NER any unplanned outages shown to be primarily caused or initiated by a fault or other event on a third party system e.g. intertrip signal, generator outage, customer installation — outages on assets that are not providing prescribed transmission services outages for personal safety that are not related to the activity of owning or operating a transmission network outages that are only for the purpose of assisting with operational security, for example where a lower voltage parallel circuit is taken out of service to assist with transfers across an interconnector network constraints related to network support services in accordance with clause 5.6.2 of the NER dispatch intervals (for a network outage constraint) that are affected by: a manifestly incorrect input to the dispatch algorithm (as determined by AEMO under clause 3.9.2B of the NER) a constraint applied by AEMO that does not accurately reflect or is otherwise inconsistent with the network capability that the TNSP advised AEMO a scheduling error mandatory restrictions under clause 3.12A of the NER AEMO declaring the spot market suspended clause 3.14.3 of the NER, or an administered price cap under clause 3.14.2 of the NER network constraints that are invoked to reflect a temporary network reconfiguration implemented by a TNSP to manage an outage. For the avoidance of the network reconfiguration may result in lower capability than during system normal but must be higher than what the capability of the network would have otherwise been during the outage. The TNSP must have notified the AER of such outage prior to the outage occurring for the exclusion to apply. NOTE: the TNSP must provide a list to the AER each year of the events that the TNSP considers should be excluded from performance results, including reasons and how the event meets the relevant exclusion definition. The AER will exercise its discretion to reject the TNSP’s exclusion claims where insufficient justification has been provided.
