Rebidding and Technical Parameters Guideline (2019)

Date initiated: 
18 September 2019
Date completed: 
27 November 2019
Effective date: 
1 July 2021


The Rebidding and Technical Parameters Guideline outlines the detail that must be contained in a rebid reason submitted to the Australian Energy Market Operator and our process for requesting additional information to verify the rebid reasons. In addition, it covers several related areas associated with the bidding and rebidding of technical parameters.

On 27 November 2019, the AER published the amended Rebidding and Technical Parameters Guideline and Final Decision to take effect from 1 July 2021.


On 28 November 2017, the Australian Energy Market Commission (AEMC) released its final rule determination to change the settlement period for the electricity spot price from 30 minutes to five minutes, starting 1 July 2021 (“5 minute settlement Rule change”). As part of this rule change, the AER must amend and publish the guidelines maintained under clause 3.8.22 in respect of rebidding.
