The AER commenced a review of its Rebidding and Technical Parameters Guideline (Guideline) on 3 March 2026 by publishing a consultation paper.
The review was required as part of the Australian Energy Market Commission’s (AEMC) December 2024 integrating price-responsive resources into the NEM rule change (IPRR rule change).
The AER is aware of the Australian Energy Market Operator’s (AEMO) proposal to temporarily pause and reset the delivery path for implementation of the IPRR framework.
As a result, the AER has decided to delay further revisions to the Guideline at this time. Instead, we will seek to re-open consultation on the Guideline after amendments to the IPRR framework are settled, and the implementation timeline clarified. This will allow amendments to the Guideline to be made as part of a single process, reducing the burden on stakeholders.
We would like to thank all stakeholders who have provided a submission in response to our Consultation paper as part of this process. We note that we will incorporate submissions already received during consultation when we re-open the Guideline.
In the interim, the AER will be shortly providing separate guidance relating to automated bidding.
