Proposal

On 7 March 2019, Energy Networks Australia wrote to the AER requesting that we delay our review of the Electricity Transmission Ring-fencing Guidelines. In March 2019, we published the letter and sought submissions from interested parties.

In response to our request for submissions, we received three submissions. One of the three submissions received was confidential and will not be published.

Discussion paper

On 15 November 2019, the AER released a discussion paper to commence a review of ring-fencing arrangements for transmission network service providers (TNSPs). This paper sought input from stakeholders to inform the development of an updated Electricity Transmission Ring-fencing Guideline (guideline).

The transmission ring-fencing discussion paper:

  • provided an overview of services that can be provided by TNSPs
  • raised potential harms and benefits from TNSP participation in competitive markets for electricity services, and
  • provided examples of ring-fencing arrangements that could be adapted to an updated transmission ring-fencing guideline.

We consider that a review of transmission ring-fencing arrangements is timely. The current guideline was first developed in 2002 and underwent minor updates in 2005. The discussion paper considered changes in markets for contestable electricity services since the initial guideline, and the AER's recently developed national approach to ring-fencing of electricity distribution networks.

Submissions - Discussion paper

We invited interested parties to make submissions on our discussion paper by 31 January 2020. We received nine submissions.

Issues paper

On 31 May the AER released an issues paper which re-commences the full review of the Transmission Ring-fencing Guideline.
