On 3 May 2017, APA Group submitted to the AER an annual tariff variation notice for the Central Ranges Gas transmission pipeline. The tariff variation notice sought to increase 2017-18 network charges for Central Ranges Pipeline users from 1 July 2017.
On 29 May 2017, the AER approved the Central Ranges Pipeline annual tariff variation proposal for the period 1 July 2017 to 30 June 2018. This was after assessing the tariff variation proposal as compliant with the Central Ranges Pipeline 2005-19 access arrangement.
