The term ‘regulated network’ refers to electricity networks or grids that the Australian Energy Regulator is responsible for providing economic and regulatory oversight.

The AER’s role is to promote the efficient investment in and delivery of energy services in the long-term interests of consumers.  Every five years the Australian Energy Regulator sets the maximum revenue that Power and Water is able to recover from customers through their network tariffs and prices that can be charged for providing network services. In this way, the Australian Energy Regulator helps to ensure that consumers pay no more than necessary for the safe, secure and reliable delivery of electricity network services.

On 1 July 2015, Power and Water adopted the national economic framework for regulating electricity networks for its three largest electricity network systems.

The first and largest is the northern network. This electricity system services approximately 150000 people and stretches from Darwin to south of Katherine. The northern network includes customers from Batchelor, Adelaide River, Pine Creek, Mataranka and Larrimah.

The second and smallest of the regulated network is Tennant Creek. This electricity system is located in the middle of the Northern Territory and services approximately 7,000 people in and around Tennant Creek.

The third regulated network is the southern electricity system servicing the Alice Springs area, which is home to approximately 28,000 people.

The AER process

Since joining the national electricity framework, Power and Water is required to submit a revenue proposal to the Australian Energy Regulator (AER) outlining its expected costs of operating and maintaining its regulated networks to deliver safe, secure, reliable, and affordable electricity to making a difference to the lives of Territorians.

As part of joining the National Electricity Rules, Power and Water is also subject to new ring-fencing requirements.

Under the National Electricity Rules of the Northern Territory, we are required to produce a Distribution Annual Planning Report and a Transmission Annual Planning Report, which we have combined into a single Transmission and Distribution Annual Planning Report.

This report covers a planning period of five years for the distribution network and 10 years for the transmission network.

The report also outlines the results of the annual planning review and presents the most recent annual load forecasts, network constraints, network performance as well as the plans and committed investments by Power and Water to address any issues.
