Revenue Proposal 2019–2023

ElectraNet’s formal Revenue Proposal 2019–2023 was submitted to the Australian Energy Regulator (AER) on 28 March 2017, outlining our expenditure plans and revenue requirements for the five-year period commencing 1 July 2018.

ElectraNet proposed significant reductions in costs, while maintaining a safe, secure and reliable transmission service.

The Revenue Proposal was built on the extensive engagement we had undertaken with our customers and stakeholders, and reflected their feedback and input.

On 26 October 2017, the AER publically released its draft decision.

In its draft determination, the AER accepted most of ElectraNet’s revenue proposal, including the full operational and capital expenditure forecasts, resulting in a proposed electricity cost reduction of about $22 for an average household in 2018-19.

ElectraNet will now respond to the draft decision by developing a revised revenue proposal by the end of the 2017 calendar year.  Consultation with our Consumer Advisory Panel and wider stakeholders will continue to inform this process.

A copy of the AER’s draft determination and the next steps in the determination process can be accessed on the AER’s website.

Preliminary Revenue Proposal

The formal Revenue Proposal builds on ElectraNet’s Preliminary Revenue Proposal (PRP) released in September 2016, which presented our indicative expenditure plans. The PRP was developed to promote effective early engagement with our customers and other stakeholders, develop shared understanding and facilitate feedback to help shape our formal Revenue Proposal.

ElectraNet’s 2016 annual transmission network stakeholder forum provided an overview of the Preliminary Revenue Proposal, together with the Network Vision which outlines the directions and priorities for the transmission network, and Customer Insights Report, which outlines the feedback gathered through the first phase of our engagement program. View the presentation to see what was covered.


Revenue Determination Process

Every five years, ElectraNet submits a Revenue Proposal to the Australian Energy Regulator (AER), which outlines the program of work and forecast revenue required to maintain and operate a safe, reliable and efficient transmission network.

The AER uses a range of evidence to review and assess the Revenue Proposal, including historic trends of past costs, benchmarking against comparable businesses and expert advice. Once the AER has independently reviewed our costs and investment plans it sets the maximum revenue we are allowed to earn for the regulated services we provide. Transmission prices are then set to recover this revenue from customers using a methodology approved by the AER.

We have implemented a detailed early engagement program to help us understand the views and priorities of South Australia’s electricity customers. This input is reflected in our plans and Revenue Proposal for the 2019–2023 regulatory period. More information is available from our Consumer Engagement information sheet.

ElectraNet is committed to genuine and ongoing engagement with electricity customers. We continue to use a range of methods to engage with our customers and stakeholders, including our Consumer Advisory Panel.

Read our Customer Engagement Outcomes Report to find out more about how we have incorporated findings and input from our stakeholder engagement into our Revenue Proposal. You can also find out more about the responses and input we received:


Framework and Approach

ElectraNet must notify the AER of the need for the Framework & Approach (F&A) process. The notification is to include ElectraNet’s approach to the application of a number of guidelines and schemes for the next regulatory control period.



Draft F&A published

The AER publishes a position paper on a draft F&A for consultation. This sets out the AER’s proposed approach to the application of the following:

  • Service Target Performance Incentive Scheme
  • Expenditure Efficiency Benefit Sharing Scheme (EBSS) and Capital Expenditure Sharing Scheme (CESS)
  • Expenditure forecast assessment guidelines
  • Whether depreciation will be based on forecast or actual capital expenditure in updating the regulatory asset base

Expenditure Forecast Methodology

ElectraNet advises the AER of its approach to forecasting capital and operating expenditure.
