On 31 October 2025, the AER received an application from APA under rule 80 of the National Gas Rules (NGR) seeking an advance determination for capital expenditure for the Victorian Transmission System (VTS). APA submitted updates to its application on 10 and 14 November 2025 – incorporated in the application we are publishing.
APA's application is to support investment to expand the South West Pipeline. APA is seeking a determination that its proposed capital expenditure is conforming (under rule 79 of the NGR) so that it will be included in the regulatory asset base as part of its 2028-33 access arrangement. We have decided to undertake public consultation before making a determination.
APA’s application is to install 2 new compressor stations and reconfigure an existing compressor station at a cost of $195.3 million. APA’s application also describes alternative investment options to expand the South West Pipeline’s capacity, involving partial or full looping (doubling) of the existing pipeline.
We will hold an online public forum on Thursday 11 December 2025 at 10am AEDT. Register to attend the public forum on Eventbrite [external link].
We encourage interested stakeholders to provide written submissions by Monday, 19 January 2026. Submissions can be emailed to ResetCoord
