On 29 April 2022, we released our final decision on Powerlink's transmission revenue determination for the 2022–27 period. Our decision is set out in the final decision document. As most issues were settled at the draft decision stage or required only minor updates, we have not prepared any supporting attachments to the final decision document. In these circumstances, our draft decision reasons form part of this final decision.

The AER commissioned reports that it took into account when making its final decision.

Pricing methodology

On 31 January 2023, the AER published its final decision on transmission pricing methodologies with amendments for system strength pricing (approved amended pricing methodology). The approved amended pricing methodology supersedes the pricing methodology approved in the AER’s 29 April 2022 final determination. All other aspects of the determination remain as per the AER’s 29 April 2022 final determination.
