On 19 April 2017, Australian Gas Networks (AGN) submitted to the AER an annual tariff variation notice for AGN's South Australian (SA) Distribution Network. The tariff variation notice sought to increase 2017-18 network charges for AGN's (SA) users from 1 July 2017.
On 22 May 2017, AGN (SA) submitted a revised tariff schedule to correct for a minor clerical error.
On 29 May 2017, the AER approved the AGN (SA) 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 AGN (SA) 2016-21 access arrangement.
