Understand your bill

Each year, the WA State Government reviews Horizon Power’s fees and charges and sets the price that our customers pay for electricity, known as ‘tariffs’. This amount is always less than the actual cost to deliver power to your business - the WA Government subsidises the difference.

Your bill is made up of two main parts:

  • A fixed charge (the cost to run power to your business)
  • A variable charge (the cost for each unit of electricity you use)
Electricity prices

About your energy bill

Your bill includes how much energy your business is using, how that compares to the previous year and how the charges are calculated.

  • How do I read and understand my account summary?

    Account summary

    The Account summary explains how we’ve calculated your bill and when payment is due. It includes any credits or outstanding amounts, plus any new charges.

    Balance from last bill

    The Total of last bill is the total owing amount from your last bill. The amount you have paid since your last bill was issued is listed under Payments.

    The balance from your last bill will display as either 'Overdue amount' (if you have an outstanding amount) or ‘Balance’ (if your account either has a zero balance, or is in credit).

    New charges this bill

    This bill displays new charges incurred for the current bill period. 

    On the back of your bill, you can see a breakdown of your current charges (including your tariff and supply charges, concessions, rebates and how much energy you used this bill period).

    Amount to pay and when

    The Total due amount is how much you need to pay. If you are in credit a minus sign (-) will show in front of the amount.

    Payable by is your payment due date. If you see ‘direct debit on’ here, this means you are on a direct debit plan, and the date shown is the date your money is withdrawn from your account.

  • What are my supply details?

    Energy supply details

    Your Invoice number is different to your account number and is different with each bill.

    The Supply period is the date for which you've been billed. The billing cycle will either be 60 or 61 days depending on the number of days in the month.

    The Supply address is the address we have supplied electricity. If you have multiple accounts, this will show which address this bill relates to.

     

     

    Your payment options are listed within the payment slip, at the bottom of your bill.

    This includes direct debit, BPAY, credit/ debit card payments, mail, Centrepay or at your local post office. Learn more about these payment options and the direct debit plans available. 

    You will need your payment number to pay your bill online, orwith BPAY (in addition to your Biller Code).

  • How much energy did I use?

    Consumption graph

    This graph shows your household’s average daily energy use so you can see how it compares to your last bill and the same period last year – it’s a great way to see how you’re tracking.

    Average cost

    It includes the average number of kilowatt hours (kWh) you have used each day and your average electricity costs each day. This is based on your average daily use, your tariff and the number of days in this billing period.

  • How do I pay my bill?

    Ways to pay your bill

    Your payment options are listed within the payment slip, at the bottom of your bill. This includes direct debit, BPAY, credit/ debit card payments, mail, Centrepay or at your local post office. If you’re on a direct debit plan, this section will be blank.

  • Where is my meter reading information?

    Usage calculations

    On the back of your bill, the Usage calculations list the tariff applied to your account, the date your meter was read, and how much energy you used this period. 

    When your meter was read

    Your meter was last read on the Reading date. If the Reading type is ‘Normal’, it means we have done an accurate reading directly from the meter. If you see ‘Estimated’ here, it means a direct meter reading could not be completed and an ‘estimated’ reading using your historical data has been used. 

    How much energy you used

    Equals total units used is the number of kW units of energy used since your last bill. Any Renewable Energy Buyback is displayed as kW (units) of excess solar sent back to the grid.

  • Where can I check any products, rebates or adjustments?

    Balance brought forward details

    You will only see this section on your bill if there’s an unpaid balance on your account from the previous billing period. 

    Current account charges

    Your energy costs for this bill are itemised here - including your supply charge and usage charges.

    Credits, products and adjustments

    This section itemises any solar credits, concessions or rebates credited to your bill and any additional fees or charges you have incurred.

     

     

    Here's a closer look at these charges:

    Account charges
    • Tariff type: the amount you pay for the electricity used is based on what tariff type you are on. This bill shows the customer is on an A2 Residential tariff.
    • Tariff charges: the number of electricity units used and (tariff rate) cost per unit in this billing period. GST is added as a separate line item. 
    • Supply charge: the charge to supply the electricity to your supply address. This is charged on a daily basis, whether you use electricity on that day or not.
    Products, credits and adjustments
    • Buyback (solar credit): if you have solar installed, this shows a credit for any units of solar electricity that have been fed back to the network as shown in this example. We buy each unit of electricity at a set price. If your buyback scheme has an on-peak and off-peak price, or if you receive your bill between seasons, you will see multiple rates listed here.
    • Rebates or subsidies: if you receive any concessions, rebates or subsidies, this will appear here as a credit on your account and shown with a minus sign (-).
    • Fees: any fees charged to your account will appear here. Example of fees include paper bill, overdue notice, Australia Post payment and credit card payment.
