Cost allocation method

The Australian Energy Regulator (AER) is responsible for the regulation of electricity network charges and also the approval of our Cost Allocation Methodology.

Network charges are the tariffs that we can charge customers and generators to access our network and for the distribution of electricity via our network.

Our Revised Cost Allocation Method 2015-20 (PDF 1.5 mb) for the regulatory control period to 30 June 2020 was approved by the AER in November 2018. It outlines the principles we'll use to allocate costs and is published in compliance with regulatory requirements.

Also, our Cost Allocation Method 2020-25 (PDF 293.1 kb) was approved by the AER in November 2018, as part of preparations for the five-year regulatory control period from July 2020. It was developed in conjunction with Ergon Energy and applies from 1 July 2020.
