RAB roll-forward 2015–16 and 2016–17

Status
In effect
Final report
30/05/2019

Aurizon Network maintains a record of the value of its existing assets for regulatory pricing, called a regulatory asset base (RAB). Aurizon Network rolls forward its RAB each year, adjusting for indexation, depreciation, disposals, transfers and the addition of approved capital expenditure. The approved 2017 access undertaking requires Aurizon Network to annually seek the QCA’s approval of its proposed roll-forward of the RAB.

The roll-forward of the RAB takes into account the QCA’s approved capital expenditure and calculates other components, such as inflation and depreciation, in accordance with schedule E of the 2017 access undertaking.

Upon request from Aurizon Network, we agreed to delay our review of the 2015–16 and 2016–17 RAB roll-forward. Aurizon Network received an extension until one month after the final approval of the 2017 draft access undertaking. The extension requests and approval letters can be found here.

Aurizon Network’s 2017 access undertaking came into effect on 21 February 2019.

Aurizon Network submitted its 2015–16 and 2016–17 RAB roll-forward amounts on 21 March 2019, followed by an addendum to the initial submission on 15 May 2019.

We approved the RAB roll-forward proposals on 29 May 2019.
