The DMO is a comparison price set by the Australian Energy Regulator (AER) each year. It’s designed to be a reasonably priced energy offer that small businesses and residential customers can choose to be on as a safety net if they don’t want to shop around and compare options within the competitive energy market.
If you live in an area where the DMO is available, retailers will use the comparison price set by the AER as a benchmark for their own market offers, and the price difference will be listed as a percentage (e.g. ‘this offer is 12% less than the comparison price set by the AER’).
The DMO was introduced to ensure Australians don’t pay an unreasonable amount for their electricity and is the most electricity retailers can charge you on a standing offer. It also serves as a comparison price set by the Australian Energy Regulator (AER) for retailers when they set their own competitive market offers. Essentially, the DMO serves to make sure you, the customer, aren’t overpaying for your electricity while also ensuring energy retailers are able to maintain their business.
The DMO price determination is updated yearly, with the final decision going into effect on 1 July each year to correctly reflect the current electricity market conditions. While the exact amount you’ll be charged will vary based on your electricity use, your distribution zone and the type of tariff you’re on, the average yearly electricity bill while on the DMO for 2026-2027 is listed below:
| Distribution zone | Residential, flat rate tariffs | Residential, time of use tariffs |
|---|---|---|
| Ausgrid | $1,899 (3,900 kWh annual usage) | $1,893 (3,900 kWh annual usage) |
| Endeavour Energy | $2,328 (4,900 kWh annual usage) | $2,320 (4,900 kWh annual usage) |
| Essential Energy | $2,604 (4,600 kWh annual usage) | $2,530 (4,600 kWh annual usage) |
| Energex | $1,988 (4,600 kWh annual usage) | $1,914 (4,600 kWh annual usage) |
| SA Power Networks | $2,334 (4,000 kWh annual usage) | $2,276 (4,000 kWh annual usage) |

The DMO is only available to those living in unregulated areas of the National Electricity Market (NEM). This includes:
There is no DMO in Victoria (VIC), however, the Victorian Default Offer (VDO) will be available to you instead, which is set by the Essential Services Commission (ESC). The DMO is also not available in the ACT (but they do have similar energy regulation in place, known as the reference price), or in the Northern Territory, Tasmania or Western Australia, where electricity is more regulated.
If you live in a home with an embedded network, the DMO also won’t be available to you. Instead, you’ll be receiving your electricity through your embedded network manager that on-sells electricity to you after purchasing it from an electricity retailer. Examples of an embedded network are an apartment block, shopping centre or retirement village.
The DMO is a government-regulated comparison price set by the Australian Energy Regulator (AER), whereas market offers are set by individual retailers and are typically cheaper than the DMO. This is because, unlike the DMO, market offers may also have incentives, discounts and other perks.
Typically, you’ll be on the DMO only if you chose not to engage in the electricity market by comparing the options on the market and shopping around, or if the benefit period of your market offer expired and you were rolled on to your retailer’s standing offer.
To know if you’re on a great electricity plan, you’ll need to consider your usage and budget and then compare options available from a range of providers.
In terms of cost, your retailer is obliged to tell you each quarter whether they have a cheaper option than the electricity plan that you’re currently on. This may benefit you if you haven’t changed electricity plans in more than a year, as your rates have probably changed with the loss of discounts or perks.
However, the best way to help lower your power bills is to compare plans yourself. By shopping around, you can compare different deals and discounts to find a plan that best suits the energy needs of you and your household.
