Commencement date

The Australian Energy Regulator (AER) has commenced a review of the Ring-fencing Guideline (electricity distribution) v4 and the Shared Asset Guideline v2. The review will consider whether the guidelines appropriately manage the risks of cross-subsidisation, discrimination and unfair competitive advantage, while ensuring consumers receive appropriate benefits where regulated assets are used for other purposes.

We have published a call for input, which explains why we are undertaking this review now and sets out the proposed scope and approach for the review. We are asking stakeholders for their views to help us refine the review’s scope, identify priority issues and develop draft changes to the guidelines.

Consultation on the call for input closed Wednesday 6 August 2026. The AER has now published submissions received during consultation.
