Pricing and tariffs FAQs
Why the tariff prices change
Every year, the Utilities Commission of the Northern Territory reviews the costs of water, sewerage, and electricity and sets the prices. This means that the prices you pay for these services can change from one year to the next.
Water and sewerage retail pricing
The pricing order sets the retail prices that customers may be charged for water supply and sewerage services.
Electricity retail pricing
The pricing order sets the retail prices that customers may be charged for electricity and related services.
Application of domestic power tariff rates
The domestic tariff is applicable for premises intended to be used for residential purposes, excluding serviced apartments, but including:
- electricity used on vacant land zoned forresidential purposes
- living premises of retirement villages(must be separately metered).
A split rate explained
A split rate is a way to calculate your charges when your bill covers more than one period, like when it crosses the end of the financial year.
How the split rate works
We divide your usage into the previous (last year) and new financial years (this year). We calculate part prices using the current rate.
Power retailers
Power and Water is responsible for electricity distribution across the Northern Territory. Your power retailer charges you for electricity services.
We only retail power in some specific remote areas, including Nhulunbuy, Alyangula, and Jabiru. Another retailer issues your power bill if you live in Darwin, Katherine, Tennant Creek or Alice Springs.
Seniors and concessions
Your water and power costs may be assisted by the Northern Territory Concession Scheme and the Northern Territory Seniors Recognition Scheme.
Application of commercial power tariff rates
The commercial tariff is applicable for premises intended to be used for non-residential purposes, including:
- electricity used on vacant land zoned for commercial purposes
- temporary supply (ie for building purposes)
- motels, hotels, serviced apartments and anyform of temporary accommodation
- shops, offices, warehouses and industrial/manufacturing plants
- mining enterprises
- farms.
2025–26 Networks Tariffs
In accordance with the AER’s 2024–29 Distribution Determination , Power and Water submitted its 2025–26 Network Pricing Proposal to the AER for approval.
On 15 May 2025, the AER approved our proposed 2025-26 network tariffs and charges . These new rates apply from 1 July 2025 to 30 June 2026.
Why your bill changes from one financial year to the next
You may notice that your invoice looks different when it goes across the financial year. This is because we use split rates to make sure we charge you correctly when there are changes in the tariff prices during this time.
Estimate your usage
You can use this calculator to find the costs for your power or water use over a given period of time, such as a weekend, a month, or a quarter.
What you will see on your bill
When your bill crosses over the end of the financial year, you will see two separate lines for your charges.
One line will show the charges for the previous financial year, and the other line will show the charges for the new financial year.
This helps you see how the rates have been applied and understand your bill better.
