On 27 February 2025, version 4 of the Australian Energy Regulator’s (AER) electricity distribution ring fencing guideline (Guideline) came into effect. Read the Guideline on the AER’s website.
The Guideline applies to all electricity distribution network businesses, referred to as Distribution Network Service Providers (DNSPs), and oversees the extent to which DNSPs 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 DNSPs with their related contestable businesses.
The following documents outline how we’re complying with the Guideline.
Note: As at 31 December 2025:
- There is one AusNet-requested waiver currently in effect, details of which are included in our Waivers Register.
- There are two class waivers granted by the AER, details of which are included in our Waivers Register.
- There are two expired waivers, details of which are included in our Waivers Register.
- There are no regulated stand-alone power systems used by AusNet to provide other services.
- The information sharing register contains details of information shared to date under the information sharing protocol.
