General enquiries - Retailer Reliability Obligation


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 final Rules came in to effect on 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.

Opt-in guideline

As set out in Rule 11.116.5, the AER must make and publish final Opt-in Guidelines by 30 June 2020. It will not be possible for parties to opt-in prior to the AER publishing this guideline, even if a reliability instrument has already been made.

On 19 March 2020 the AER published the draft opt-in guideline for consultation and a decision document responding to stakeholder submissions. 

The draft guideline sets out the opt-in process, including the information to be contained within the opt-in register, the processes for registering, deregistering or amending registration, and the criteria for assessing opt-in eligibility.


We invite interested stakeholders to make written submissions in response to the draft guideline, by the close of business 9 April 2020.

Submissions should be sent electronically to with the following title in the email: For Consultation – Draft Opt-in Guideline.

Alternatively, submissions can be mailed to:
