Power and Water Corporation has responsibility for planning, building and maintaining reliable electricity networks to transport electricity between electricity generators and electricity customers in the Northern Territory.

The following diagram illustrates the different distribution services provided by Power and Water’s Power Services business unit.

Standard control services are central to electricity supply and therefore relied on by most (if not all) customers such as building and maintaining the shared distribution network. Most distribution services are classified as standard control.

The Australian Energy Regulator (AER) regulates these services by determining prices or an overall cap on the amount of revenue that may be earned for all standard control services. The costs associated with these services are shared by all customers via their regular electricity bill.

Alternative control services are customer specific or customer requested services. The AER sets service specific prices to provide a reasonable opportunity to enable the distributor to recover the efficient cost of each service from customers using that service.

There are no negotiated services in the Northern Territory, and the AER has no role in regulating the unclassified services that Power and Water provide.

2019-24 Distribution Determination

As the economic regulator, the Australian Energy Regulator sets the maximum amount of revenue Power and Water can recover from the provision of standard control services over a five-year regulatory period. It also sets the prices or quoting approach for alternative control services.

On 30 April 2019, the AER released its final decision on Power and Water’s electricity distribution determination for the 2019-24 regulatory control period.

In its final decision, the AER also approved Power and Water’s Tariff Structure Statement for the 2019-24 regulatory control period.
