The AER has released its final guidance note on amending the post-tax revenue model (PTRM) as issued under the National Electricity Rules (NER) for use in non-contestable revenue determinations under the Electricity Infrastructure Investment Act 2020 (NSW) (EII Act) and Electricity Infrastructure Investment Regulation 2021 (NSW) (EII Regulation).
Our final guidance note outlines the AER’s expectations about which functions of the NER-prescribed electricity transmission PTRM need to be amended to be consistent with the requirements of the EII framework. The final guidance ensures the minimal amount of modifications are made to the model such that a Network Operator or other stakeholders familiar with the NER PTRM are able to operate and apply the EII PTRM for non-contestable revenue determinations.
Our final guidance note should be read in conjunction with:
- The non-contestable guideline
- The latest published electricity transmission PTRM handbook
- The latest final decision for electricity transmission PTRM amendment
2024 update of the guidance note
In November 2024, the AER updated and released a new version of the guidance note for amending the NER prescribed electricity transmission PTRM, for use in NSW non-contestable infrastructure projects under the EII framework.
