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 RRO Rules were published on 9 May 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 Forecasting Best Practice Guideline

As set out in RRO Rules 4A.B.5, the AER must create a Forecasting Best Practice Guideline. The guideline enables the AER to effectively discharge its responsibility with regard to the RRO, provides Australian Energy Market Operator (AEMO) with guidance and direction in developing its Reliability Forecast Guidelines and on the preparation of its forecasts, and provides confidence to market participants concerning the quality and transparency of reliability forecasts and the supporting process conducted by AEMO.

On 23 May 2019 we published the Draft Interim Forecasting Best Practice Guideline for consultation. 

A final Interim Forecasting Best Practice Guideline, taking in to account stakeholder submissions, will be published by 30 September 2019.


Submissions on the Draft Interim Forecasting Best Practice Guideline closed on 19 June 2019.


As part of the consultation on the guideline, the AER hosted a workshop on 31 May 2019.
