General Power System Risk Review

In accordance with rule 5.20A of the National Electricity Rules (NER), AEMO is required to undertake a General Power System Risk Review (GPSRR) and prepare a GPSRR report for the National Electricity Market (NEM) at least annually. From 2023, the GPSRR replaces and expands on the scope of the previous Power System Frequency Risk Review (PSFRR).

The GPSRR is an integrated, annual review of major power system risks in the National Electricity Market (NEM). The purpose of the GPSRR is to review:

  • A prioritised set of risks comprising contingency events and other events and conditions that could lead to cascading outages or major supply disruptions.
  • The current arrangements for managing the identified priority risks and options for their future management.
  • The arrangements for management of existing protected events and consideration of any changes or revocation.
  • The performance of existing emergency frequency control schemes and the need for any modifications.

Current status

AEMO is currently working on the 2024 GPSRR and has now completed the approach paper consultation.
