Pricing and tariffs FAQs

Why tariff prices change

Every year, the Utilities Commission of the Northern Territory opens in a new window 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 opens in a new window
The pricing order sets the retail prices that customers may be charged for water supply and sewerage services.

Electricity retail pricing opens in a new window
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 for residential purposes
  • living premises of retirement villages, which must be separately metered.

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, for example for building purposes
  • motels, hotels, serviced apartments and any form of temporary accommodation
  • shops, offices, warehouses and industrial or manufacturing plants
  • mining enterprises
  • farms.

A split rate explained

A split rate is a way to calculate your charges when your bill covers more than one period, such as when it crosses the end of the financial year.

How the split rate works

We divide your usage into the previous financial year and the new financial year. We calculate each part using the tariff that applied during that period.

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.

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.
