On 4 May 2021, the AER determined that a cost pass through was appropriate and meets the National Electricity Rule requirements. However, the AER has determined that some costs originally proposed by TransGrid should not be included and that the pass through amount should be recovered from electricity users over a longer time frame. The AER approved a pass through amount of $49.8 million ($nominal) to be recovered over the following three regulatory years:
- $15,663,472 ($nominal) to be recovered in 2022–23
- $16,593,229 ($nominal) to be recovered in 2023–24
- $17,578,174 ($nominal) to be recovered in 2024–25.
