AER - Final decision - Transgrid 2024–29 - WSB non-contestable - December 2023

On 15 December 2023, we released our final decision on Transgrid's revenue determination for the 2024-29 regulatory control period for the Waratah Super Battery project. 

Our final decision is set out in the determination document below and accompanying attachments. As a number of issues were settled at the draft decision stage or required only minor updates, we have not prepared all attachments. In these circumstances our draft decision reasons form part of this final decision. The draft decision attachments that haven’t changed and may be referenced as part of this decision are Appendix A – Assessment approaches, Appendix C – Adjustment Mechanisms. Confidential Appendix D – Rate of return averaging periods will not be published.
