AEMO undertakes a Power System Frequency Risk Review (PSFRR) at least every two years, in accordance with the National Electricity Rules (NER). The purpose of the PSFRR is to review the potential for “non-credible” power system contingency events to cause frequency changes large enough to initiate cascading outages or major supply disruptions.
On 27 November 2020, AEMO released the stage 2 draft report on the PSFRR.
The AER provided the submission below on the draft report on 11 December 2020.
