Matter Under Consultation

In accordance with Clause 5.20A.1, AEMO has undertaken a Power System Frequency Risk Review (PSFRR) that specifically considers the loss of multiple generating units in the South Australian region when South Australia is importing energy from Victoria.

Under such conditions (as occurred on 28 September 2016) the loss of multiple generating units could lead to the loss of the Heywood Interconnector, and islanding of South Australia from the rest of the NEM, followed by cascading loss of the remaining South Australian generating units and black system.

The PSFRR recommends the implementation of an interim Emergency Frequency Control Scheme (EFCS) as the most efficient way to mitigate this risk.

Final Report

Feedback

Clause 50.20A.3 requires AEMO to publish this draft PSFRR and invite written submissions within 10 working days.
