Revenue Determination Process

Every five years, ElectraNet submits a Revenue Proposal to the Australian Energy Regulator (AER) for formal assessment and approval through the revenue determination process. The proposal outlines the program of work and forecast revenue required to maintain and operate a safe, reliable and efficient transmission network.

Once approved, transmission prices are then set to recover this revenue from customers using a methodology approved by the AER.

Preliminary Revenue Proposal 2023-24 to 2027-28

On 14 July 2021 ElectraNet published its Preliminary Revenue Proposal (PRP) for the forthcoming period, which will run from 1 July 2023 until 30 June 2028.

The Preliminary Revenue Proposal summarises our developing plans for South Australia’s electricity transmission network and the essential services we will provide in the coming regulatory period. It is the precursor to our formal Revenue Proposal, which we will submit to the AER in January 2022.

The Preliminary Revenue Proposal sets out our indicative capital and operating expenditure programs and invites views on them from our stakeholders. Between now and January 2022, when we submit our formal proposal, we will further develop and refine our plans and programs and, in so doing, will consider the input of our stakeholders. This is essential to ensure we produce a targeted and well-tested set of proposals that deliver the right outcomes for our customers and that satisfy our aim to prepare a proposal that is supported by our customers and the Australian Energy Regulator.

Final determination 2018-19 to 2022-23

On 30 April 2018, the AER released its final determination on ElectraNet’s Revenue Proposal for the five-year regulatory period commencing 1 July 2018.

In its final determination, the AER accepted ElectraNet’s reduction in transmission charges, which delivers a bill reduction of $17 for a typical residential customer and a $33 decrease for a typical small business customer in 2018-19.

The AER accepted ElectraNet’s proposal to reduce capital expenditure by 39% and its operating expenditure by 9%.

The AER also accepted small amendments to the operating expenditure proposed by ElectraNet in its revised Revenue Proposal which was submitted on 22 December 2017. These changes were in response to new obligations to address system security challenges in South Australia.

We implemented a detailed early engagement program to help us understand the views and priorities of South Australia’s electricity customers. This input was reflected in our plans and Revenue Proposal for the 2019–2023 regulatory period.

More information about the final determination can be accessed on the AER’s website.
