The Coal Network Capacity Company conducts capacity assessments of Aurizon Network’s central Queensland coal network, including developing and amending the system operating parameters, in accordance with cl. 7A of the 2017 access undertaking.
The initial capacity assessment report assesses the deliverable capacity of each coal system, having regard to the way each coal system operates in practice, from 1 July 2019 to 30 June 2024.
The initial capacity assessment report sets out the constraints that reduce, or are likely to reduce, deliverable network capacity and identifies any existing capacity deficits (where the deliverable capacity will not meet committed capacity). It also includes specific causes for any existing capacity deficits and provides potential solutions for addressing them, where possible.
Aurizon Network has provided its detailed response to the initial capacity assessment report, outlining its views on the causes, and possible transitional solutions, for existing capacity deficits, and the process for implementation.
The Coal Network Capacity Company has considered Aurizon Network’s response and made a recommendation on which transitional arrangements to reduce the capacity deficits.
We are not seeking comments from stakeholders on the independent expert’s recommendations at this time.

We have made a determination on the initial transitional arrangements we consider will most efficiently and effectively address existing capacity deficits identified in the respective systems.
We will make further determinations in relation to the remaining transitional arrangements, in due course.

The annual capacity assessment report updates the assessment of the deliverable network capacity at network, coal system, and mainline and branch line level. This includes reviewing the system operating parameters for the system and considering whether any adjustments are required.
The 2022 annual capacity assessment report is the first assessment undertaken since the initial capacity assessment (released in October 2021).
