We have now published our draft decision on Marinus Link's Stage 1, Part B (Construction costs) electricity transmission determination for the 2025–30 regulatory control period.

Consumer engagement is a valuable input to our determination. Stakeholders can assist in our process by providing their views on aspects of the initial draft decision.

On Tuesday, 27 May 2025, we hosted a predetermination conference to provide stakeholders the opportunity to ask questions about our initial draft decision. The presentation slides are available below.

Interested stakeholders are invited to make a submission on both our initial draft decision and Marinus Link's revised proposal (once submitted) by Friday, 15 August 2025. 

Submissions can be sent to vic2026aer [dot] gov [dot] au (marinuslink2025[at]aer[dot]gov[dot]au)

Alternatively, submissions can be sent to:
Dr Kris Funston
Executive General Manager 
Australian Energy Regulator
GPO Box 1313 
Canberra ACT 2601

Submissions should be in Microsoft Word or another text readable document format.

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. For more information see the ACCC/AER Information policy.

On 21 May 2025, Marinus Link Pty Ltd (MLPL) wrote to the AER requesting a revised approach to the expectations set in our Commencement and Process Paper including concurrent feedback loop and revenue  proposal processes.
