United Energy – Ring-fencing compliance report 2018

Ring-fencing compliance
Release date: 
31 May 2019


The AER has reviewed United Energy’s ring-fencing compliance report for the 2018 regulatory year, and the accompanying independent assessment of compliance undertaken by Deloitte. Deloitte’s reasonable assurance assessment confirmed that United Energy has by and large established appropriate compliance controls as required by clause 6.1 of the Electricity Distribution Ring-fencing Guideline. United Energy reported one breach of the Guideline in 2018. We do not consider this a material breach and are satisfied with the actions that United Energy has committed to undertake to remedy the breach.


The Ring-fencing Guideline requires DNSPs to separate their regulated business activities, costs and revenues from other unregulated services. In doing so, the Ring-fencing Guideline aims to promote competition and consumer choice in contestable markets for electricity services, and it aims to ensure efficient costs in the delivery of regulated network services by DNSPs. The Ring-fencing Guideline was first published on 30 November 2016 and updated in October 2017. All DNSPs were required to comply with obligations in the Ring-fencing Guideline by 1 January 2018.

Under the Ring-fencing Guideline, DNSPs are required to prepare an annual ring-fencing compliance report each regulatory year, accompanied by an assessment of compliance by a suitably qualified independent authority.

All DNSPs are required to submit ring-fencing compliance reports and accompanying independent assessments of compliance to the AER with four months following the end of the regulatory year to which the compliance report relates. As Victorian DNSPs’ regulatory year aligns with the calendar year, Victorian DNSPs submit their compliance reports by 30 April each year. All other DNSPs, whose regulatory years align with the financial year, must submit annual reports and accompanying independent assessments of compliance to the AER by 30 October each year.
