Endorsed variation event—2020–21 AT5 reference tariff and QCA levy
On 17 July 2020, Aurizon Network applied to adjust reference tariffs for 2020–21 as a result of two endorsed variation events. Aurizon Network sought a change to the AT5 tariff arising from a change in the pricing from a transmission entity, and a change to the QCA levy associated with a variation in the QCA fees.
We were satisfied in both cases that the requirements for an endorsed variation event were met and approved the applications.
