For many Australian households, opening a recent electricity bill in 2026 has been a confusing experience. You might have actively reduced your energy consumption, perhaps even installed solar panels, yet the fixed daily supply charge on your bill has undeniably crept upwards. The direct answer is that these rising fixed charges are a result of significant increases in network costs and a deliberate regulatory shift by bodies like the Australian Energy Regulator (AER) and Victoria’s Essential Services Commission (ESC) to recover more of these fixed costs through a daily fee, rather than per-unit usage rates. This is happening even as overall wholesale electricity prices, driven by an influx of renewables, are generally falling.
This guide will unpack the complex factors behind this trend, provide current 2026 figures, and offer actionable strategies to mitigate the impact on your household budget.
The Disappearing Federal Rebate: A Perceptual Hit
Before delving into the core reasons for rising supply charges, it’s crucial to acknowledge a major factor contributing to the perception of higher bills: the end of the universal federal Energy Bill Relief Fund. This scheme provided households with up to $300 in 2024-25 and a further $150 (via two $75 quarterly instalments) in the first half of 2025-26. The final payment landed on 31 December 2025.
“From 1 January 2026: No new universal federal energy credits are in place. Bills from the January 2026 quarter onwards reflect full retail prices.”
Without this automatic credit, the underlying costs of electricity become fully visible, making any increases in supply charges feel more pronounced. While state-based concessions remain available for eligible concession card holders, the broad federal support has ceased.

Why Network Costs Are Driving Up Supply Charges
The primary driver behind the escalating daily supply charges is the rising cost of building, maintaining, and upgrading Australia’s electricity network – the poles, wires, and substations that deliver power to your home. Network charges typically account for a substantial portion of your electricity bill, ranging from 30% to 50%.
Several factors are contributing to these escalating network costs in 2026:
-
Massive Infrastructure Investment for Renewables: Australia is undergoing a rapid energy transition, moving away from fossil fuels towards renewable energy. This requires unprecedented investment in new, large-scale transmission lines and distribution upgrades to connect remote wind and solar farms to population centres. Major projects like VNI West, HumeLink, and the Central-West Orana Renewable Energy Zone are experiencing significant cost blowouts, collectively running into billions of dollars. For instance, the VNI West project’s cost has risen from $3.6 billion to an estimated $7.0-$7.6 billion.
-
Ageing Infrastructure: Much of Australia’s existing grid infrastructure is ageing and requires substantial investment to ensure reliability and safety. These maintenance and upgrade costs are passed on to consumers.
-
The ‘Cost-Reflective’ Tariff Shift: Energy regulators, including the AER and ESC, are increasingly pushing for tariff structures that are more “cost-reflective.” The argument is that the costs of maintaining the physical network are largely fixed, irrespective of how much electricity flows through it. Therefore, recovering a greater proportion of these fixed costs through a daily supply charge, rather than purely through usage rates, is deemed more equitable and stable.
This means that even if you have rooftop solar and consume less grid electricity during the day, the network still needs to be maintained for when you do draw power (e.g., at night) or export your excess solar. The fixed cost of this infrastructure doesn’t decrease just because some customers are drawing less from the grid.
2026 Daily Supply Charge Figures Across States
While overall Default Market Offer (DMO) and Victorian Default Offer (VDO) prices generally fell from 1 July 2026 in most states due to lower wholesale costs, many retailers simultaneously increased their daily supply charges.
Here’s a snapshot of typical daily supply charges in 2026 from major retailers and DMO/VDO determinations:
| State/Network | Typical Daily Supply Charge (AUD) | Notes |
|---|---|---|
| NSW (AGL Standing Offer) | $1.66 | Based on AGL NSW Standing Offer (166.18778 c/day) |
| NSW (EnergyAustralia Standing Offer, Ausgrid) | $1.66 | Based on EnergyAustralia NSW Standing Offer (166.22870 c/day) |
| NSW (Origin average) | $1.05 | Average across various plans, may be lower than standing offer |
| QLD (Origin, SE QLD example) | Up to $1.92 | Reported increase from $1.43 to $1.92/day for an Origin customer |
| SA (AGL typical) | $1.10 - $1.30 | General range for AGL customers |
| VIC (AusNet Services VDO) | $1.2939 | Victorian Default Offer from 1 July 2026 |
| VIC (CitiPower VDO) | $1.5219 | Victorian Default Offer from 1 July 2026 |
| VIC (Jemena VDO) | $1.6818 | Victorian Default Offer from 1 July 2026 |
| VIC (Powercor VDO) | $1.6978 | Victorian Default Offer from 1 July 2026 |
| VIC (United Energy VDO) | $1.5400 | Victorian Default Offer from 1 July 2026 |
As you can see, daily supply charges can vary significantly by state, network, and even retailer plan. The reported increases, such as an Origin customer in SE QLD seeing their daily supply charge jump by $0.495 (approx. $180 annually) from $1.43 to $1.92, demonstrate the direct impact on household bills.
What You Can Do to Manage Rising Fixed Charges
While fixed charges are harder to influence than usage rates, there are still effective strategies to manage your overall electricity costs in 2026:
-
Shop Around and Compare Plans Regularly: Despite rising supply charges, the retail energy market remains competitive. Retailers often restructure their offers, and a plan with a slightly higher daily supply charge might still offer significantly lower usage rates or better solar feed-in tariffs, leading to overall savings. Use government comparison websites: Energy Made Easy for NSW, QLD, SA, ACT, and TAS, and Victorian Energy Compare for Victoria.
-
Embrace Solar and Battery Storage: Reducing your reliance on grid electricity, especially during peak times, remains the most powerful way to cut your overall bill. While solar primarily addresses usage charges, combining it with a home battery can further reduce your grid interaction, offsetting the impact of fixed supply charges over time. Batteries allow you to store cheap daytime solar for evening use, minimising costly peak-time imports.

-
Leverage Smart Energy Management and New Tariffs: Many retailers are now offering innovative tariffs designed to encourage smart energy use. From 1 July 2026, major retailers like AGL, Origin, and EnergyAustralia are required to offer the Solar Sharer Offer to eligible smart meter households in DMO regions (NSW, QLD, SA). This provides three hours of free electricity daily (e.g., 11 am to 2 pm in NSW and SE QLD, 12 pm to 3 pm in SA), with a 24 kWh daily cap. While you don’t need a battery, a home battery system can significantly amplify the benefits by storing this free power for later use.

-
Check State-Specific Concessions: Don’t forget to check if you’re eligible for any state or territory energy bill relief programs or concessions. These can provide valuable offsets to your overall bill. Eligibility often depends on holding certain concession cards.
Bottom Line
Australia’s electricity daily supply charges are indeed rising in 2026, primarily driven by the substantial costs of upgrading and maintaining our national electricity network to support the energy transition. This trend is exacerbated by regulatory shifts favouring more ‘cost-reflective’ fixed charges and the cessation of federal energy bill relief. While usage rates may be decreasing in many areas, the increased fixed daily fee means that even low-usage households are feeling the pinch. Your most effective strategy is to actively compare electricity plans on government comparison websites to find a market offer that best suits your consumption patterns and to seriously consider investing in rooftop solar and home battery storage to reduce your overall reliance on the grid and maximise savings from new smart tariffs like the Solar Sharer Offer.
