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.
Energy Networks Australia has requested that we delay the timing of this review given the many other regulatory changes and reviews currently underway impacting on the regulation of transmission networks. This includes the Australian Energy Market Commission's review of the Coordination of Generation and Transmission Investment and the Energy Security Board's work on actioning the Integrated System Plan.
The AER had intended to complete this review by December 2019. If we decide to delay the timing of this review, we expect that we would review the Guideline during 2020.
