Fixed electricity supply charges are a non-negotiable part of your power bill, paid daily regardless of how much energy you consume. In 2026, these charges often range from around $1.20 to over $1.90 per day across Australia, translating to hundreds of dollars annually before you even switch on a light. While usage rates may see reductions in some states this financial year, fixed supply charges are, in many cases, increasing. The most effective way to slash these charges, or at least significantly offset their impact, is by proactively comparing and switching to competitive market offers from retailers, leveraging smart meter tariffs, and exploring solar PV and battery solutions.
What Are Fixed Electricity Supply Charges?
Your electricity bill is typically composed of two main elements: usage charges (variable, based on how much electricity you consume) and supply charges (fixed, a daily fee for being connected to the grid). Fixed supply charges cover the costs associated with maintaining the poles, wires, and other infrastructure that deliver electricity to your home, as well as some retailer operating costs.
These charges are set by your electricity distributor and passed on by your retailer. They can vary significantly between states and even within different distribution zones of the same state. Understanding this fixed component is crucial, especially for low-usage households, as it can represent a substantial portion of the overall bill.
Default Market Offer (DMO) & Victorian Default Offer (VDO) 2026-27: Your Benchmark
The Australian Energy Regulator (AER) sets the Default Market Offer (DMO) for NSW, South East Queensland, and South Australia. Victoria has its own Essential Services Commission (ESC) set Victorian Default Offer (VDO). These offers act as a safety net, representing the maximum price retailers can charge customers on standing offers – plans you might be on if you haven’t actively switched or your market contract has expired.
Crucially, the DMO and VDO also serve as a reference price, helping you compare market offers. Most customers are on market offers, which are typically cheaper than the DMO or VDO.
Here’s a snapshot of typical residential daily supply charges for 2026-27 (GST inclusive) under the DMO/VDO framework and specific retailer standing offers:
| State/Distribution Zone | Typical Daily Supply Charge (2026-27) | Notes |
|---|---|---|
| NSW (DMO Benchmark) | ~A$1.20 - A$1.66/day | Average around A$1.20/day (June 2026), with some retailer standing offers like AGL’s Ausgrid Single Rate at A$1.66/day. |
| Victoria (VDO) | A$1.19 - A$1.38/day | Varies by distributor: United Energy (A$1.19), CitiPower (A$1.21), Jemena (A$1.27), AusNet Services (A$1.28), Powercor (A$1.38). |
| South East QLD (DMO) | A$1.92/day | Energex residential customers DMO 8 cap is 192.02 c/day. |
| South Australia (DMO) | Increase of 1.4% for flat rate | While a specific daily charge isn’t widely published for DMO 8, flat rate residential customers will see a 1.4% increase in their annual bill. |
| ACT (ActewAGL Standing Offer) | A$1.34 - A$1.71/day | ActewAGL Home plan A$1.34/day, Home Saver A$1.71/day. |
“From 1 July 2026, many households will pay less for the electricity they use, but significantly more for their daily supply charge, with some increases reported above 70 percent.”
This highlights that while overall bills might decrease in some areas due to lower wholesale energy costs, the fixed daily supply component is often rising.
Strategy 1: Compare and Switch Retailers – The Immediate Win
The single most impactful action you can take to manage fixed electricity supply charges is to regularly compare energy plans and switch retailers. Market offers from retailers are almost always more competitive than the DMO or VDO standing offers.
- Use Comparison Websites: Government-backed platforms like Energy Made Easy (for NSW, QLD, SA, TAS, ACT) and Victorian Energy Compare (for Victoria) are free, independent tools that allow you to compare plans based on your actual usage data.
- Look Beyond Headline Discounts: Focus on the total annual cost, including both usage and supply charges. Some retailers, including major players like AGL, Origin, and EnergyAustralia, have been noted for increasing their fixed daily supply charges, even as overall DMO prices fall. A plan with a lower usage rate but a significantly higher daily supply charge might not be the best value, especially for lower-usage households.
- Negotiate: Don’t be afraid to contact your current retailer and ask them to match or beat a better offer you’ve found elsewhere.
Strategy 2: Leverage Smart Meters for Smarter Tariffs
If you have a smart meter, you’re already equipped to access more dynamic tariff structures that can help offset fixed costs, even if they don’t directly reduce them. Smart meters record your electricity consumption in short intervals (e.g., 30 minutes), enabling Time-of-Use (TOU) and demand tariffs.
- Time-of-Use (TOU) Tariffs: These plans charge different rates based on the time of day (peak, shoulder, off-peak). By shifting high-energy activities (like running washing machines or dishwashers) to off-peak or shoulder periods, you can significantly reduce your overall usage costs, making the fixed daily supply charge a smaller proportion of your total bill.

- Solar Sharer Offer (SSO): A new federal government initiative, effective from 1 July 2026, the Solar Sharer Offer provides three hours of free electricity daily for eligible households with smart meters in NSW, South Australia, and South East Queensland. The free window is typically 11 am to 2 pm in NSW and SE QLD, and 12 pm to 3 pm in SA, with a 24 kWh daily cap. This can be a game-changer for offsetting costs, even if you don’t have solar panels.

Strategy 3: Solar PV and Batteries – Offsetting Fixed Costs
While installing solar panels or a home battery doesn’t directly reduce your fixed daily supply charge, it can dramatically reduce your net electricity bill, effectively making the fixed charges less burdensome.
- Self-Consumption: Generating your own electricity with solar PV and consuming it during the day reduces the amount you draw from the grid, lowering your usage charges. The higher your self-consumption, the less you pay overall.
- Feed-in Tariffs (FiT): When your solar system generates more electricity than you use, the excess is exported to the grid, and your retailer pays you a Feed-in Tariff. While FiTs have generally decreased, they still provide a credit that can help offset your fixed supply charges.
- Home Batteries: Pairing solar with a home battery allows you to store excess solar generation for use during peak times or at night, further increasing self-consumption and reducing reliance on grid electricity. Batteries can also be crucial for maximising savings under tariffs like the Solar Sharer Offer by storing the ‘free’ midday energy for later use.

Strategy 4: Government Concessions and Rebates
The universal federal Energy Bill Relief Fund concluded on 31 December 2025. However, state and territory governments continue to offer targeted concessions and rebates for eligible households, particularly those with concession cards.
These concessions can directly reduce your overall bill, including components that cover fixed charges. Eligibility criteria and amounts vary significantly by state. For example, NSW offers a Low Income Household Rebate of A$285/year, while Queensland provides an Electricity Rebate of A$386.34/year (as of previous periods, subject to annual review).
It is essential to check your state government’s energy department website or contact your retailer to determine your eligibility. A comprehensive guide to available support can be found here: Navigating Australia’s Energy Bill Relief and Support in 2026: A Comprehensive Guide.
Understanding Your Bill
To effectively manage your fixed charges, you must understand your current bill. Locate the daily supply charge (usually listed in cents per day, c/day, or dollars per day, $/day). Also, identify your current tariff type (flat rate, time-of-use, or demand). This information is critical when comparing offers, as a seemingly good usage rate might be offset by a high daily supply charge, especially if your household has low overall consumption.
Bottom Line
While fixed electricity supply charges are an unavoidable component of your bill, you are not powerless against them. In 2026, with daily supply charges averaging from A$1.19 to over A$1.90, translating to A$434 to A$694 annually, taking action is crucial. Your most direct and effective strategy is to regularly compare electricity market offers using government comparison websites and switch to a plan that minimises your overall costs, carefully scrutinising both usage and supply charges. Beyond switching, leveraging smart meters for dynamic tariffs like the Solar Sharer Offer and investing in solar PV and battery storage can significantly offset the financial impact of these fixed fees by reducing your reliance on grid electricity. Finally, ensure you are claiming all eligible state government concessions to reduce your total energy expenditure.
