Semi-scheduled and intermittent non-scheduled generation availability under extreme high temperature
AEMO ELECTRICITY MARKET NOTICE
Refer AEMO Electricity Market Notice 72013.
AEMO's weather service provider is forecasting extreme high ambient temperatures across NEM regions. AEMO reminds semi-scheduled and intermittent non-scheduled generators to advise AEMO of any reduction in available capacity caused by temperature derating.
For any reduction in availability please ensure to:
1. Update SCADA Local Limit or, if unavailable, advise AEMO control room to implement a quick constraint to the reduced available capacity level; and
2. Update intermittent generation availability in the EMMS Portal (https://portal.prod.nemnet.net.au/#/signin) to reflect reduced plant availability as per NER 3.7B(b).
Refer to the AER Rebidding and Technical Parameters Guideline: https://www.aer.gov.au/system/files/AER%20Final%20Guidline%20-%20Rebidding%20and%20Technical%20Parameters%20Guideline%20-%2028%20February%202017.pdf

AEMO ELECTRICITY MARKET NOTICE.
AEMO has identified that a non-credible contingency event is more likely to occur in the NSW region because of the existence of abnormal conditions. Severe, extreme and catastrophic bushfire conditions are forecast for Saturday, 21 December 2019.
Catastrophic: Greater Sydney, Illawarra/ Shoalhaven and Southern Ranges.
Extreme: Greater Hunter and Central Ranges.
Severe: North Western, Northern Slopes, Southern Slopes and Monaro Alpine.
As at the time of this notice the criteria for reclassification of any non-credible contingency event have not been met, however there is a possibility of bushfires impacting multiple transmission elements in NSW on Saturday, 21 December 2019.
Conditions can change rapidly and potentially impacted plant may change. Further notices will only be published to advise of any reclassification, or when the abnormal conditions have ceased to impact the likelihood of a non-credible event occurring.
