Pricing

This section explains the electricity pricing and charges for regional Western Australian residents and businesses.

The State Government sets the price of electricity (otherwise known as tariffs), that are listed on this page. These tariffs are charged to residents and businesses across the State - in both Perth and regional Western Australia.

These electricity tariffs continue to be significantly lower than the average cost to supply as they are heavily subsidised by the State Government. Each residential customer of Horizon Power receives a subsidy of $4,000 a year from the State Government on average.

  • For Home
  • For Business

The most common tariff for residential customers is A2. This tariff is available to private dwellings (houses, home units, flats, apartments, permanent caravan park residents etc.) and offers the same flat rate regardless of when and which time of day electricity is used.

NWIS/Regional Caravan Parks

The State Government recognises that caravan parks in the North West Interconnected System (from Karratha to Port Hedland) and regional off-grid power systems may be disadvantaged if they are paying business tariffs higher than the residential tariff. As a result, Horizon Power has developed the Caravan Park Tariff Compensation Program. 

Please see below for more information about how the Scheme will affect you.
