The AER released the 2022 annual benchmarking reports for distribution and transmission on 30 November 2022.

We republished the distribution report in February 2023 to correct a labelling error in two output charts (Figure B.7 and Figure B.8 of Appendix B). This did not impact any of the results or conclusions in the report.

The AER’s annual benchmarking reports are supported by two expert reports from Quantonomics.

Quantonomics has also prepared a memorandum on options to address an ongoing technical issue with some of our econometric opex cost function benchmarking models.

The underlying data and calculations used in the benchmarking reports.

We republished the partial performance indicators file for distribution in February 2023 to correct a labelling error in two output charts (Figure B.7 and Figure B.8 of Appendix B in the distribution report).

Under the National Electricity Rules, the AER must consult with network service providers in the development of performance reports and we may also consult with other stakeholders who we consider have an interest in the relevant performance report. We received the following submissions from electricity network service providers and other industry stakeholders.
