Matter Under Consultation

The Power System Frequency Risk Review (PSFRR) is an integrated, periodic review of 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, in consultation with Transmission Network Service Providers (TNSPs), completed a PSFRR for the NEM, considering:

  • Non-credible contingency events which AEMO expects could likely involve uncontrolled frequency changes leading to cascading outages or major supply disruption.
  • Current arrangements for managing such non-credible contingency events.
  • Options for future management of such events.
  • The performance of existing Emergency Frequency Control Schemes (EFCSs).
