2028-33 Transmission Determination Proposal

As co-owner and operator of Murraylink, we are responsible for preparing the next Regulatory Proposal, that will begin on 1 July 2028 and run through to 30 June 2033, on behalf of Energy Infrastructure Investments.

Since September 2025, we have been working closely with a dedicated and diverse stakeholder group to shape the 2028–33 Regulatory Proposal. The results of this collaboration will culminate in the submission of our Regulatory Proposal to the AER on 31 January 2027.

Ahead of submitting our Regulatory Proposal to the AER, we will publish an ‘Overview of the draft Regulatory Proposal’ on this website for stakeholder feedback.

Regulatory Investment Test for Transmission (RIT-T) for Insulated Gate Bipolar Transistors (IGBTs)

We are engaging on a RIT-T to manage IGBT obsolescence for Murraylink. IGBTs are integral to the reliability of Murraylink as they perform the precise switching to convert AC to DC and vice versa.

As the highest cost of the credible options identified is >$8 million but less than $54 million, we intend to adopt the expedited RIT-T process that entails two key stages.

  • The first stage will be the delivery of a Project Specification Consultation Report (PSCR) that will be published on this website. This will be followed by a minimum 12 week consultation period.
  • The second stage will be a Project Assessment Conclusion Report that will also be published on this website for consultation for 30 days.

To keep stakeholders informed of the process and ensure their views are captured and considered in both reports, we are engaging with interested stakeholders. If you would like to be included in the engagement program, please email yoursay@apa.com.au with the title Murraylink IGBT RIT-T.
