Overview

Our Transmission Network Ring-fencing Guideline was published in 2002 and underwent a minor update in 2005. With the review and implementation of ring-fencing arrangements for electricity distribution completed in 2018, we intend to review the existing transmission ring-fencing guideline.

The purpose of ring fencing is to separate the competitive and regulated parts of network businesses to protect the long term interests of consumers. That is, ring-fencing supports the development of competitive markets for energy services and efficient investment in network and customer services. For consumers, ring-fencing helps the development of competitive markets to improve outcomes for consumers.

The indicative timetable outlines AER’s timeline for the review of the transmission ring-fencing guideline. We will commence with an issues paper in September 2019.
