On 30 June 2026, we published our preliminary position paper for Transgrid’s System Strength Project revenue determination for the 2026–31 regulatory period. 

Our preliminary position paper follows consultation on Transgrid’s revenue proposal and provides an early indication of our assessment. Our preliminary positions are informed by stakeholder submissions and highlight areas of Transgrid’s proposal which we are likely to not accept or consider would benefit from focused feedback from stakeholders. Our assessment identifies risk and labour and indirect costs as the two key focus issues for stakeholder consideration and feedback. 

We are seeking submissions on our preliminary position paper to help inform our revenue determination.

Interested stakeholders are invited to email submissions by 28 July 2026 with the subject line 'Submission on the System Strength Project'. Email your submissions to REZaer [dot] gov [dot] au (REZ[at]aer[dot]gov[dot]au). 

Alternatively, submissions may be sent to: 

Mr Scott Haig
Acting General Manager
Renewable Energy Zones Branch
Networks Regulation
Australian Energy Regulator
GPO Box 3131
CANBERRA, ACT 2601

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

We request parties wishing to submit confidential information: 

•           clearly identify the information that is the subject of the non-disclosure claim,

•           provide a non-confidential version of the submission in a form suitable for publication.

We will host an online public forum to allow stakeholders the opportunity to ask questions on Transgrid’s revenue proposal and the issues we raised in our preliminary position paper before consultation closes. 

The public forum will be held from 10:30 am to 12:00 pm (AEST) on 16 July 2026. If you are interested in attending the public forum, please register to attend on Eventbrite by 5pm (AEST) on 14 July 2026.
