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 requested input from stakeholders to inform the development of an updated Electricity Transmission Ring-fencing Guideline.
We invited interested parties to make submissions on our discussion paper by 31 January 2020. We received nine submissions in total.
The purpose of ring-fencing is to prevent regulated businesses from discriminating in favour of their related parties to the disadvantage competitors operating in these markets. Ring-fencing helps consumers by supporting competition in markets for electricity services and the efficiency of regulated network services.
