Power System Frequency Risk Review

The Power System Frequency Risk Review (PSFRR) is an integrated, periodic review of major power system frequency risks associated with non-credible contingency events in the National Electricity Market (NEM). 

In accordance with Clause 5.20A.1 of the National Electricity Rules (NER), AEMO is undertaking a PSFRR for the NEM, considering:  

  • Non-credible contingency events which AEMO expects could involve uncontrolled frequency changes leading to cascading outages or major supply disruption. 
  • Current arrangements for managing such non-credible contingency events, including the performance of existing emergency frequency control schemes (EFCSs).  
  • Options for future management of such events.
