On 31 October 2025, AusNet Services submitted its transmission regulatory proposal for the period 1 April 2027 to 31 March 2032 (2027-32). This submission and supporting materials are included below.

Under clause 6A.9.4 (NER version 109) of the NER, the AER's transmission determination for AusNet Services must set out the Negotiated Transmission Service Criteria (NTSC). The NTSC determined by the AER must give effect to, and be consistent with, the negotiated transmission service principles set out in clause 6A.9.1 of the NER.

By virtue of clause 11.98.8 of the NER, the provisions for negotiated transmission services in version 109 of the NER continue to apply in Victoria.

We invite energy consumers and other interested parties to make submissions on the proposed Negotiated Transmission Service Criteria for AusNet Services by Friday, 13 February 2026. Written submissions should be sent electronically to AERresets2027-32aer [dot] gov [dot] au (AERresets2027-32[at]aer[dot]gov[dot]au) and addressed to Kris Funston, Executive General Manager, Australian Energy Regulator. Alternatively, submissions can be mailed to GPO Box 3131, Canberra ACT 2601.

On 12 December 2025, the AER will publish an Issues Paper for public consultation. It will highlight some of the key elements of AusNet Services transmission revenue proposal and identify the issues that are likely to be the focus of the AER’s assessment and engagement with stakeholders. 

Consumer engagement is a valuable input to the AER's determination. Stakeholders can assist in this process by providing their views on aspects of the AusNet’s transmission revenue proposal. 

On 17 December 2025, the AER will host an online public forum for stakeholders to ask questions and share their views on the AusNet's 2027-32 transmission revenue proposal.
