Submissions open on Basslink revised revenue proposal

Today we commenced consultation on APA’s revised revenue proposal for the Basslink interconnector. The revised revenue proposal follows the AER’s Draft Decision , published 12 September 2025. 

As part of the revised proposal, APA is seeking to recover $461.2 million ($ nominal, smoothed) in revenue over the 2026‑30 period, $32.4 million more than the September Draft Decision. The revised proposal includes a proposed opening regulatory asset base value of $742.6 million as of 1 July 2026, an increase of $22.1 million from the Draft Decision. 

Basslink’s proposal allocates 75% of regulated revenue to the Victoria region and 25% to Tasmanian region. We do not have a decision-making role in approving or rejecting a Transmission Network Service Provider’s revenue allocation within a region. 

Our role is to review the prudency and efficiency of the proposed costs to ensure consumers pay no more than necessary. 

Invitation for submissions

We invite interested parties to make submissions on the revised proposal and our Draft Decision, by Friday, 12 December 2025. 

Submissions should be email to: reset [dot] coordaer [dot] gov [dot] au (reset[dot]coord[at]aer[dot]gov[dot]au)

Stakeholder submissions will inform our Final Decision, expected to be released in February 2026.

Background

Basslink is a 500 MW undersea transmission cable which links Loy Yang in Victoria to George Town in Tasmania. In 2022, APA Group acquired Basslink Pty Ltd, the owner and operator of Basslink. 

On 19 May 2023, APA lodged an application:

• to convert Basslink’s network services from market network services to prescribed transmission services
• requesting us to commence, and determine, the process of making a transmission determination for Basslink. 

On 26 June 2025, we published our Final Decision on the application from APA to convert the service of the Basslink interconnector from a market network service to a prescribed transmission service.
