On 15 March 2018, Evoenergy (ActewAGL) submitted to the AER an annual tariff variation notice for the ACT, Queanbeyan and Palerang gas distribution network. The tariff variation notice sought to increase 2018-19 network charges for ActewAGL's users from 1 July 2018.
On 27 April 2018, Evoenergy submitted a revised tariff model, correcting for a few minor errors.
On 30 April 2018, the AER approved the Evoenergy revised annual tariff variation proposal for the period 1 July 2018 to 30 June 2019. This was after assessing the revised tariff variation proposal as compliant with Evoenergy's 2016-21 access arrangement.
