Maintenance cost approval
Each year we approve actual maintenance costs for each of Aurizon Network’s coal systems.
In our assessment, we focus on the extent to which Aurizon Network’s actual maintenance costs, for each coal system, are consistent with the approved maintenance strategy and budget (MSB), subject to identified materiality thresholds.
Where the maintenance cost claim is consistent with the approved MSB, we will approve Aurizon Network’s actual expenditure. Where there are material differences, we assess those maintenance costs and activities on the basis of prudency and efficiency. We have regard to Aurizon Network’s obligations to ensure that committed capacity is delivered and to coordinate outages with other supply chain participants.
The assessment framework is set out in cl. 7A.11.5 of the 2017 access undertaking.
