What your business pays depends on how much power you use, your network area, and your tariff, so there is no single national figure. The clearest way to judge a fair rate is the Default Market Offer, the reference price the Australian Energy Regulator sets each year.
Most small businesses do better on a competitive plan than the regulated default. The AER reports about 15 percent of small businesses remain on the Default Market Offer, with the rest on market offers (AER, June 2026). That gap is where switching pays off.
The AER counts you as a small business if you use under 100 megawatt hours of electricity a year. That is roughly a spend below $30,000. Energy consumption is the biggest single driver of your annual cost.
| What drives your cost | Why it matters |
| Annual energy use in kWh | Higher consumption lifts your total bill and can move you onto a different tariff. |
| Network area | Each distribution zone sets its own charges, so similar businesses can pay different rates. |
| Tariff type | Single rate, time of use, and demand tariffs each price your usage differently. |
| Business size | Staying under 100 MWh a year keeps you in the small business bracket with standard plan pricing. |
Your exact rate depends on your network area, total energy use, and tariff type. Compare current business plans for your postcode to see real figures for your premises.
