Ring-fencing

As the regulated distribution network service provider, Power and Water complies with the Australian Energy Regulator’s (AER) Electricity Distribution Ring-fencing Guidelines and obligations. These are set out in the National Electricity Rules as enforced in the Northern Territory (NT NER).

While our network operations are governed by the AER Ring-fencing Guidelines, Power and Water’s other electricity supply operations including gas services and System Control are still governed by the Utilities Commission’s NT Ring-fencing Code.

Ring-fencing is an electricity network term referring to the separation of regulated and competitive business activities where a regulated entity also offers services into a competitive electricity market.

Ring-fencing addresses potential or perceived risks of cross-subsidies or discrimination. It is designed to ensure equal opportunity to all providers of unregulated electricity services.

Ring-fencing under the Utilities Commission of the Northern Territory

Power and Water is governed by the obligations set out in the Utilities Commission of the Northern Territory (UC) Ring-fencing Code for other areas of business including our gas supply business and System Control. Power Services as the Distribution Network Service Provider is now governed by the AER Ring-fencing Guideline as set out below.

The Utilities Commission’s NT Ring-fencing Code aims to promote and safeguard competition and fair and efficient market conduct in the electricity supply industry by promoting the simulation of competitive market conduct and preventing the misuse of market power.

More information can be found on the Utilities Commission’s Electricity Ring-fencing Code webpage.

Australian Energy Regulator’s (AER) Ring-fencing guideline

The AER’s Ring-fencing Guideline for Electricity Distribution came into effect for Power and Water on 1 July 2019.

These guidelines detail Power and Water’s obligations around information sharing and disclosure, publishing of certain registers and preparing an annual compliance report.

However, not all AER Guideline provisions apply in the Northern Territory due to the nature of our broader operations.

These exemptions are primarily around the obligation for us to observe legal and functional separation of services and staff sharing.

Specific Power and Water obligation information can be found below.

More general information can be found on the Australian Energy Regulator’s Ring-fencing webpage.

Information sharing protocol and register

Power and Water is committed to fair dealing and to encouraging competition in contestable markets in compliance with the AER Ring-fencing Guideline.

Under clause 4.3 of the AER Ring-fencing Guidelines, where Power and Water shares ring-fenced information with a Related Electricity Service Provider (RESP), Power and Water is required to provide access to the confidential ring-fenced information to other legal entities on an equal basis. Power and Water’s Information Sharing Protocol outlines how and when this will be done.

Power and Water will publish all valid applications for access to ring-fenced information on the information register. Applications for access to ring-fenced information must be made using the application form and emailed to PNRegulationGroup.PWC@powerwater.com.au.

Clause 6.17.1B of the National Electricity Rules - Northern Territory includes derogations, or exemptions, for how the guideline applies in the NT.

This includes the requirement for us to functionally separate staff, offices, and branding in order to separate our regulated network services from the other services we provide.
