Draft Transmission Cost Report and Consultation
The Draft Transmission Cost Report forms part of the 2021 Inputs, Assumptions and Scenarios Report (IASR), and was published on 28 May 2021. The draft report set out:
- AEMO’s proposed approach to transmission cost estimation for the 2022 ISP.
- A description of the new Transmission Cost Database which incorporates a cost estimating tool.
- A summary of the design, capacity and cost estimate for each candidate transmission project in the 2022 ISP.
- A request for feedback on the proposed approach to transmission cost estimation, the Transmission Cost Database, and the transmission augmentation options under consideration.
The Draft Transmission Cost Report was supplemented by the Transmission Cost Database and associated documents as outlined below. AEMO sought stakeholder feedback on any of these documents.
Submissions to Draft Report
All stakeholders were invited to provide a written submission to any matters discussed within the Draft Transmission Cost Report or the supporting documents.
Submissions did not need to address all areas discussed. Submissions closed on Friday 25 June 2021.
