2020-25 Revenue determination process

Every five years we prepare a Regulatory Proposal outlining our plans and forecasting expenditure for the distribution network for the next five-year period. The Australian Energy Regulator (AER) makes a revenue determination based on our proposal. The AER determination approves the levels of capital investment, operating cost and overall funding required to complete our program of work.

We have consulted with customers and stakeholders on our plans for the next five years and our 2020-25 Revised Regulatory Proposal was submitted to the AER in December 2019. The AER issued its revenue determination in June 2020. Our Talking Power website has more information about this process.

Information on the current 2020-25 revenue determination can be found on the AER website.

Regulatory reporting

We have developed a Monitoring, Evaluation and Compliance Strategy (MECS) that outlines how we will use best endeavours to comply with the reliability and customer service standards outlined in the Essential Services Commission of South Australia’s Electricity Distribution Code (EDC).

We regularly provide detailed information to the AER for monitoring purposes, and costs must be allocated in accordance with our approved Cost Allocation Method 1350KB PDF.

The National Electricity Rules also requires Distribution Service Providers to develop, publish and maintain, a Distribution Loss Factor Methodology 296KB PDF.


In late 2016, the Australian Energy Regulator (AER) released a new ring-fencing guideline to promote competition in the provision of electricity services. It introduced:

  • new legal and accounting separation obligations
  • new functional separation obligations.

We have made changes to comply with this new guideline with the lowest cost to our customers and minimum impact to the business.
