Understanding your electricity bill

Your electricity bill isn't just a record of the electricity you use. It also lists thing like the supply charge, sometimes a discount, and sometimes a rebate credit, all adding up to one total that you need to pay.

This guide breaks down the different parts of a standard electricity bill in Australia, based on guidance from the Australian Energy Regulator (AER), plus real charge examples from network distributor Ausgrid.

Quick facts

• Your bill is made up of a fixed daily supply charge and a variable usage charge, plus any other fees, credits or rebates that apply to your account.
• Retail customers under the National Energy Retail Law (NSW, QLD, SA, ACT and TAS) must be billed at least once every 100 days.
• On a typical NSW residential bill, generation costs make up the largest single share of the total, followed by network distribution and retail costs.
• A standing offer is the default plan you're on if you haven't chosen or negotiated a market offer, and it's usually not the cheapest option available.
• Estimated meter readings must be clearly marked on your bill and are not the same as an actual reading of your usage.

What's on your electricity bill

Every retailer's bill layout looks a little different, but the Australian Energy Regulator confirms certain details must appear on every bill issued to customers in NSW, QLD, SA, ACT and TAS. Victorian bills follow separate rules set by the Essential Services Commission.

On the first page, you should find your name, address and the bill date, along with the total amount to pay, any credits or amounts owed from a previous bill, and the due date.

The AER's own illustrative example bill shows this first page should also carry your retailer's name and ABN, along with your unique National Meter Identifier (NMI), which should match the number physically on your meter.

Further into the bill, usually on the second page, you'll find the billing period (the exact dates your usage covers), your meter readings, and your distributor's details.

Your distributor is the company that owns and maintains the poles and wires carrying electricity to your property. It's a different business from your retailer, the company that actually bills you.

Fixed charges vs variable charges

The supply charge is a fixed daily cost for having electricity connected to your property, and it applies whether you use one kilowatt hour or a thousand.

The exact amount depends on which network serves your area. Under the AER's 2026-27 Default Market Offer tariff caps, the maximum flat-rate daily supply charge is $1.66 for Ausgrid customers in Sydney, $2.72 for Essential Energy customers in regional NSW, $1.92 for Energex customers in South East Queensland, and $1.80 for SA Power Networks customers in South Australia.

These are regulatory caps that apply to standing offer customers specifically, not a guarantee of what you'll pay on a market offer, but they show how much this single charge can shift depending on where you live.

The usage charge, also called the consumption charge, is what you pay per kilowatt hour (kWh) of electricity used.

The rate depends on your tariff type. A flat rate tariff charges the same rate no matter when you use electricity. A time of use tariff charges different rates depending on whether you're using power during peak, off-peak or shoulder periods.

Using Ausgrid as an example shows how much this can shift a bill: 100 kWh used during peak hours at $0.65 per unit costs $65, while the same 100 kWh used off-peak at $0.30 per unit costs only $30.

For a full state-by-state breakdown of when peak and off-peak periods actually apply, see our guide to off-peak electricity times.

What you pay for on your electricity bill

Electricity doesn't arrive at your home as a single cost. It passes through several stages, and each one adds a charge to your bill.

Based on Ausgrid's breakdown of an average annual residential energy bill in NSW, the cost splits roughly as follows.

This breakdown is specific to NSW and reflects one distributor's data. The split will differ in other states, particularly for the state-specific line items.

Generation and distribution together make up close to seventy per cent of the total, which is why wholesale price movements and network charges affect your average electricity bill more than any other cost category.

Standing offers vs market offers

A standing offer is the default plan your retailer puts you on if you haven't chosen or negotiated anything else.

If a fixed-term market plan expires and you take no action, your account typically rolls onto a standing offer. Standing offers rarely include discounts and are usually more expensive than market offers.

A market offer is a plan you've actively chosen or negotiated with a retailer. These can include conditional discounts, and pricing varies significantly between retailers. If you're not sure which one you're on, check the plan name on your bill or call your retailer directly and ask.

How often you're billed

Some retailers offer bill smoothing, where your estimated annual cost is divided into smaller, more regular payments (weekly, fortnightly or monthly) rather than one larger quarterly amount.

This doesn't change how much you pay overall, but it can make budgeting more predictable.

Estimated vs actual meter readings

If your bill is based on an estimate rather than an actual meter reading, it must be clearly marked on the bill. The AER notes this explicitly as one of the details to check when reviewing your bill for accuracy.

Estimated readings happen when a meter reader can't access your meter, or when your meter doesn't support remote reading.

Retailers typically base an estimate on your own historical usage, or on the average usage of a comparable household if no history exists.

If your estimated bill looks unusually high, contact your retailer and ask about submitting a self-read, since most retailers accept a photo of your meter as proof of actual usage.

Additional fees you might see

Beyond the supply and usage charges, some bills include extra fees under specific circumstances.

According to the AER, these can include an establishment fee for setting up a new account, a termination fee for leaving a contract early, and a payment processing fee for certain payment methods such as credit card.

Not every retailer charges all of these, and they should be itemised separately on your bill rather than folded into your usage charge.

Getting help if you're struggling to pay

Retailers are required under the National Energy Retail Law to assist customers experiencing payment difficulties.

This includes offering a payment plan, and in some cases a hardship program with additional support. If you can't reach an agreement with your retailer, the Energy Ombudsman in your state can help.

Separately, temporary rebates and ongoing concessions are available to eligible households, including pensioners, concession card holders and people with certain medical conditions.
