On 1 March 2023, version 4 of the Australian Energy Regulator’s (AER) Transmission Ring-fencing Guideline (Guideline) came into effect. Read the Guideline on the AER’s website.
The Guideline applies to all electricity transmission network businesses, referred to as Transmission Network Service Providers (TNSPs), and oversees the extent to which TNSPs can provide contestable services. The objective of ring-fencing is to promote the development of competitive markets. The Guideline aims to prevent cross-subsidisation and discriminatory behaviour by TNSPs with their related contestable businesses.
The following documents outline how we’re complying with the Guideline.
