In accordance with clause 7A.5 of UT5, we are required to determine which transitional arrangements will most efficiently and effectively resolve the existing capacity deficits identified in each coal system.

We have made three determinations outlining appropriate transitional arrangements to progress to address identified existing capacity deficits in the respective systems.

We will make further determinations in relation to the progression of appropriate transitional arrangements, in due course.

Initial capacity assessment report

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 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.
