• Electricity pricing

    Electricity prices determined by the State Government

    The Western Australian Government regulates Synergy’s and Horizon Power's electricity prices in line with the following electricity by-laws:

    This means that Horizon Power and Synergy must make the regulated price available to their small use customers and some larger customers.

    The electricity tariff by-laws set out the fees and charges Synergy and Horizon Power may charge during the course of supplying electricity to customers. Changes to electricity tariffs, fees and charges are considered by the Western Australian Government annually as part of the State Budget process.

    Uniform Tariff Policy

    The Uniform Tariff Policy means that small use Synergy and Horizon Power customers are all charged the same rate. This includes customers in remote regions, where the costs to supply electricity are considerably higher.

    The extra costs of supplying electricity to these areas are funded by:

    • the Tariff Equalisation Contribution through electricity network charges in the South West Interconnected System (SWIS); and
    • Western Australian Government subsidy.
