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 has undertaken 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.

AEMO has prepared the 2022 Power System Frequency Risk Review (PSFRR) final report under clause 5.20A of the National Electricity Rules (NER). The final report is published in two parts the main report and the appendices.
