Annual benchmarking reports 2020

Effective date: 
27 November 2020


In the annual benchmarking reports, we 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.

Enquiries about these reports should be directed to the AER at, or call on 1300 585 165.
