On 29 January 2019 ARTC submitted an application to vary its 2008 Interstate Access Undertaking. The variation seeks to change the following:
- extend the term of the undertaking to 29 February 2020
- set new Indicative Access Charges based on current charges escalated by CPI, except for Adelaide to Kalgoorlie segments, which ARTC proposes to escalate by CPI + 2 %
- include an obligation on ARTC to draft a reconciliation mechanism into any future replacement or extended undertaking, that reconciles the charges set out in this variation against the charges in any replacement or extended undertaking accepted by the ACCC.
ARTC's application and its supporting materials are available below.
