Matters under consultation

In March 2024, the Australian Energy Market Commission (AEMC) released its final determination on the Improving security frameworks for the energy transition (ISF) rule change.

The rule evolves existing frameworks with the aim of ensuring sufficient security services are provided as the power system continues to transition to higher penetrations of inverter-based resources (IBR). It requires AEMO to assess and enable the necessary security services in operational timeframes to ensure that the power system is secure day-to-day.

The enablement of security services under the ISF Rule commences 2 December 2025 and must be conducted in accordance with the Security Enablement Procedures that are to be published by 31 August 2025. The Procedures will set out a methodology for determining and meeting system security requirements, in addition to requirements in agreements to be entered by Transmission Network Service Providers.

AEMO is now consulting on the new Security Enablement Procedures in accordance with new NER 4.4A.6(a) and the standard rules consultation procedure in clause 8.9.2 of the National Electricity Rules (NER).

Submissions are due to NEMReform@aemo.com.au by 5pm AEST on Thursday 8 May 2025. Please note that submissions will be published, other than confidential material, as per AEMO’s Consultation submission guidelines.
