Retailer reliability obligation - Draft interim reliability instrument guideline

Retailer Reliability Obligation
Date initiated: 
4 April 2019
Effective date: 
31 July 2019


The Australian Energy Regulator (AER) is supporting improving reliability in the NEM by implementing the Retailer Reliability Obligation (RRO) alongside the Energy Security Board (ESB).

The ESB was tasked to develop the National Electricity Rules (the Rules) necessary to implement the Obligation. The draft Rules were published for stakeholder consultation on 8 March 2019. A revised rules package was released on 9 May 2019. The final Rules are proposed to be in place by 1 July 2019.

As set out in the Rules, the AER is responsible for developing a number of Guidelines on certain aspects of the RRO.

Draft Interim Reliability Instrument Guideline

As set out in draft Rule 4A.C.12, the AER must create a Reliability Instrument Guideline. The guideline explains how the AER will have regard to the criteria in the rules when assessing whether or not to make a reliability instrument following a request from AEMO, sets out the AER consultation process with stakeholders when deciding on a reliability instrument request and defines what information AEMO must provide the AER as part of a reliability instrument request and the form of this information.

On 4 April 2019 we published the Draft Interim Reliability Instrument Guideline for consultation.

A final Interim Reliability Instrument Guideline, taking in to account stakeholder submissions, will be published by 31 July 2019.


Submissions on the Draft Interim Reliability Instrument Guideline closed on 24 April 2019.


As part of the consultation on the guideline, a workshop was held on 31 May 2019.
