Electricity prices and charges (Business)

This section contains the Horizon Power electricity tariffs and charges for regional Western Australian businesses.

There are two distinct areas for our customers:

  • North West Interconnected System in the Pilbara
  • Regional non-interconnected systems

Horizon Power customers in these areas pay the same price for their electricity, according to the tariff appropriate for their type of business.

Electricity tariffs increased on 1 July 2013. Please click here for more information.

The C2 tariff is available to small voluntary and charitable organisations. Customers seeking supply under this tariff must apply in writing to Horizon Power, providing evidence which clearly illustrates that the customer meets all conditions as listed in the Energy Operators (Regional Power Corporation) (Charges) By-Laws 2006.

Power Price Equity Scheme for Caravan Park Residents

Please see the residential page for information on this Scheme.

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. For details refer to the Tariff Compensation Program below.

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