Understand your bill
Each year, the WA State Government reviews our fees and charges and sets the price that our customers pay for electricity, known as ‘tariffs’. If your bill is like most of our residential customers’ bills, it’s made up of two main parts:
- A fixed charge (the cost to deliver power to your home)
- A variable charge (the cost for each unit of electricity you use)
When you live in regional and remote areas, it costs more to deliver power to your home than the price that you are actually charged - but the WA State Government subsidises the price. In 2022-23, this subsidy will be $175 million for regional WA, or $3,593 per customer connection.
About your energy bill
Knowing about the different parts which make up your energy bill can be helpful if you’re trying to save energy and manage your household budget.
-
What are my account details?
The first few numbers you'll see in the top left of your bill is your account number. You'll need your account number handy if you ever need to contact us, or register online for My Account.
Your account information, including the name on your account and postal address, are located under your account number. It's important to let us know if your postal address, email address or phone number changes - you can do this online with My Account.
-
How much energy did I use?
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 if you were at the same address.
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.
You can view your energy use in more detail with MyAccount. MyAccount provides your daily and hourly energy use, your current spend and an estimate of what your next bill is likely to be, based on your average daily usage. Learn more about MyAccount.
-
How do I pay my 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. 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 do I read and understand my account summary?
Your account summary lists:
- Total of previous bill: the amount of your last bill,
- Payments & adjustments: the amount you have paid since your last bill was issued,
- Balance: the outstanding amount on your account (if any),
- Current charges: new charges for this bill period,
- Total due: the total amount owing
- Payable by: your payment due date
Please note:
Your invoice number is different to your account number and is different with each bill.
Your supply period is approximately 60 days, so you’ll receive a bill from us about every two months.
Your supply address is the address for which we have supplied electricity and for which this bill relates to. In many cases, this will be the same as the address above but if you have multiple accounts, this will show which property this bill relates to.

Where can I check my tariff, any rebates or solar buyback credits?
On the back your bill, you can view:
- Your tariff and the cost of the electricity you have used. This is based on the number of units used in this billing period and the cost per unit. GST is added as a separate line item.
- Rebates or subsidies: if you receive any concessions, rebates or subsidies, this will appear here as a credit on your account. In this example, the customer receives the WA Government Energy Assistance Payment.
- Solar buyback credit: if you have solar installed, this shows a credit for any units of electricity that have been fed back to the network. We buy each unit of electricity at a set price per town. The buyback price is listed on your bill.
-
Where is my meter read information?
On the back of your bill, the usage calculations list your:
- Tariff - The tariff applied to your account. In this example, the customer is on the A2 Residential Tariff.
- Meter number - Your meter’s unique identifier.
- Reading date - The date your meter was read
- Current meter reading - The reading taken from your meter on your meter reading date.
- Equals total units used - The number of units used since the last bill was issued
- Your type of meter reading - ‘Normal’ means we have taken a reading from the meter, ‘Estimated’ means we have estimated your reading using historical data for your property.
- Buyback - If you have solar installed, this line shows how many units of electricity you have fed back to the network since your last bill.

How is energy measured?
You may have noticed on your bill that you are charged per ‘kWh’ for electricity – but what does that even mean? It can be pretty tricky to wrap your head around some of the energy jargon out there, but taking the time to learn will help you understand your bill.
What does ‘kWh’ stand for?
Is your bill higher than you were expecting?
Seasonal changes, new appliances, visitors in the household or a recent renovation are just a few of the factors which can cause a spike in your energy use and impact your bill.
