Annual Benchmarking Report - Distribution and Transmission 2019

29 November 2019

Overview

In the annual benchmarking reports we (the AER) examine the relative efficiency of the distribution and transmission electricity network service providers. In doing this we consider the characteristics of each network business, and how their productivity compares at the aggregate level and for the outputs they deliver to consumers. We developed the report using publically available data that we collected after an extensive consultation process that aligned with the development of our Expenditure Forecast Assessment Guideline.

The benchmarking calculations and dataset, and submissions by the network services providers, can be found at Annual Benchmarking Report 2019.
