Access Arrangement for Period commencing 2025

The Goldfields Gas Pipeline (GGP) is a 1,378-kilometre transmission pipeline extending from Yarraloola to Kalgoorlie and is operated by Goldfields Gas Transmission (GGT). Part of the GGP is a scheme (regulated) pipeline that must have an access arrangement approved by the ERA (the other portion of the pipeline is a non-scheme pipeline).

The process for gas access arrangement reviews has changed since the ERA’s last review of GGT’s access arrangement for the GGP in 2019. There are now two key stages involved in the ERA’s decision making process for an access arrangement: (a) Reference Service Proposal and (b) Access Arrangement Proposal. Under the National Gas Rules, GGT must submit a reference service proposal to the ERA 12 months before the access arrangement proposal.

On 21 December 2022, GGT submitted a reference service proposal for the GGP. The ERA published GGT’s proposal for consultation on 10 February 2023. On 21 June 2023, the ERA made a decision approve GGT’s proposal to retain the firm transportation service as the single reference service for the GGP.

On 21 December 2023 (ahead of the required submission date of 1 January 2024), GGT submitted its access arrangement proposal for the fifth access arrangement period (AA5): 1 January 2025 to 31 December 2029. The ERA published GGT’s proposal and related documents for public consultation on 29 January 2024.

Interested parties have until 8 April 2024 to comment on GGT’s proposal. The ERA expects to publish an issues paper in due course to assist interest parties in making submissions.

Further information about the access arrangement framework and decision making process can be found in the ERA’s gas access arrangement guideline.
