On 15 August 2024, the Australian Energy Market Commission (AEMC) made the Unlocking CER benefits through flexible trading rule change. This rule change introduced a number of incremental reforms intended to enable emerging and innovative CER products and services to be delivered and integrated into the National Electricity Market.

The AER has received a cost pass through application from Evoenergy seeking to recover costs expected to be incurred as a result of the rule change.

Evoenergy expects to incur $4.5 million (nominal) in incremental costs across 2025–26 and 2026–27 to undertake system and business process changes to its billing and market systems platform to implement flexible trading arrangements and comply with consequential updates to retail market and business-to-business procedures. Evoenergy has proposed an increased revenue allowance of approximately $1.5 million (nominal, smoothed) to commence recovery of these costs in 2026–27.

We invite energy consumers and other interested parties to make submissions on Evoenergy's cost pass through application by Monday, 2 March 2026.

The AER's role is to determine whether a positive change event as defined in the National Electricity Rules (NER) has occurred, and if so, what is the incremental revenue amount which should be passed through to network users. In order to best assist and inform the AER in making its determination, interested parties may wish to address the following questions:

• Does the FTA rule change meet the definition of a cost pass through event under clause 6.6.1(a1) of the NER and Evoenergy's current revenue determination?
• Is the increase in costs that Evoenergy has incurred as a result of the event material?
• Are the costs identified by Evoenergy incremental to costs already allowed for in their current revenue determination, and related solely to the occurrence of the pass through event?
• Are the decisions and actions Evoenergy has taken in relation to the event efficient?
• Are there any other factors the AER should take into account in making its determination?

Submissions should be emailed Attention: Kami Kaur, General Manager, Network Expenditure to: costpassthroughsaer [dot] gov [dot] au (costpassthroughs[at]aer[dot]gov[dot]au)

We prefer that all submissions be publicly available to facilitate an informed and transparent consultative process. We will treat submissions as public documents unless otherwise requested. All non-confidential submissions will be placed on the AER's website. For further information regarding the AER's use and disclosure of information provided to it, see the ACCC/AER Information Policy.

We request parties wishing to submit confidential information:

• clearly identify the information that is the subject of the confidentiality claim
• provide a non-confidential version of the submission in a form suitable for publication.
