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.

AEMO has prepared the draft 2022 Power System Frequency Risk Review (PSFRR) report under clause 5.20A of the National Electricity Rules (NER) and is seeking submissions from all persons interested in the PSFRR. In particular, we invite feedback regarding the methodology, findings and recommendations proposed to mitigate risks associated with priority non-credible events studied through the review.

To support this consultation AEMO is inviting participants to join a question and answer session on this year’s PSFRR on 10 June 2022 at 2.00pm (AEST). If you are interested in attending this session please email psfrr2022@aemo.com.au.

If you would like to make a submission, please email it to psfrr2022@aemo.com.au. Written submissions will be accepted until 5.00 pm (AEST) 17 June 2022.
