Many Australians are scratching their heads this Winter 2026, wondering why their electricity bills remain stubbornly high, or have even increased, despite news of falling wholesale electricity prices and Default Market Offer (DMO) reductions. The direct answer lies largely in the rising fixed daily supply charges – the cost of simply being connected to the grid – which have seen significant increases, in some cases over 70% from 1 July 2026, offsetting any savings on usage rates.
While the cost of the electricity you use (per kilowatt-hour, or c/kWh) has decreased in many regions, the unavoidable daily fee for network access has climbed. This means households with lower consumption might actually see their total bill increase, as the fixed component becomes a larger proportion of their overall cost. Combined with the natural increase in energy consumption for heating during colder months, this creates a perfect storm for higher winter bills.
The Disconnect: Wholesale vs. Retail Prices and Supply Charges
Electricity bills are complex, made up of several components: wholesale electricity costs, network costs (transmission and distribution), environmental and policy scheme costs, retail operating costs, and retail margins.
“From today [1 July 2026], many households will now start paying less for the electricity they consume, but significantly more for their daily supply charge, with some customers reporting increases of over 70%.”
Wholesale electricity costs have indeed fallen, with the Australian Energy Regulator (AER) reporting reductions of between 2% and 14% for the 2026-27 financial year. This is primarily due to increased wind and battery generation entering the National Electricity Market (NEM), reducing reliance on more expensive gas and hydro power during peak times, and lower electricity futures prices.
However, network costs – the charges for building, maintaining, and operating the poles and wires that deliver electricity – remain a dominant driver, accounting for roughly 39% to 54% of typical DMO costs. These costs are often passed directly to consumers through the daily supply charge, which is a fixed fee you pay regardless of how much electricity you consume. For example, Essential Energy residential customers in regional NSW are seeing average annual network cost increases of around $70.37 on a flat-rate tariff, effective 1 July 2026.
The AER and Essential Services Commission (ESC) in Victoria set the Default Market Offer (DMO) and Victorian Default Offer (VDO) respectively, which act as a safety net for customers on standing offers and a reference price for market offers. While these usage rates are seeing reductions in most areas for 2026-27:
- New South Wales & South East Queensland: Residential flat rate DMO prices are falling between 3.4% and 7.2%.
- Victoria: The VDO is reducing by an average of 5% for households.
- South Australia: Residential flat rate DMO prices are seeing a modest increase of 1.4%.
Despite these usage rate drops, the significant increases in daily supply charges are eroding potential savings. For instance, some Victorian distribution zones have daily supply charges for fixed flat tariffs as high as $1.6709 per day (Jemena network), with CitiPower at $1.5219 and AusNet Services at $1.2939. In NSW, ActewAGL’s standing offer supply charges can range from $1.683045 to $2.474698 per day, depending on the network and tariff.
Why Winter Consumption Amplifies the Problem
Winter naturally brings higher electricity consumption, primarily due to heating. Heating and cooling can account for up to 40% of an average household’s energy bill. Even with slightly lower usage rates, the sheer volume of energy used to keep warm, combined with the higher fixed daily supply charges, leads to larger overall bills. Appliances like electric heaters, reverse-cycle air conditioners, and hot water systems work harder in colder temperatures, contributing significantly to your kWh usage.
Federal Energy Bill Relief Has Ended
It’s crucial for consumers to note that the universal federal Energy Bill Relief Fund payments, which provided up to $300 for households in 2024-25 and a further $150 in the first two quarters of 2025-26, ended on 31 December 2025. There are no new universal federal credits in place for 2026, meaning your current bills reflect full retail prices without this government offset.
State-Specific Relief and New Offers for 2026
While universal federal relief has ceased, targeted state-based concessions and new market offers can still provide some respite:
- South Australia: The Retailer Energy Productivity Scheme (REPS) continues to offer discounted or free upgrades for energy-efficient hot water systems, reverse-cycle air conditioners, and appliances, along with incentives for Virtual Power Plant (VPP) battery connections. Eligible concession cardholders can also access the SA Concessions Energy Discount Offer with Origin Energy, providing 20% off electricity usage and supply charges, and 15% off gas usage and supply charges until at least 2029.
- New South Wales, South Australia, and South East Queensland: A significant new initiative for 2026 is the Solar Sharer Offer (SSO), introduced as part of DMO reforms. Available from 1 July 2026 to residential customers with smart meters, the SSO provides 3 hours of free electricity daily (11 am-2 pm in NSW/SE QLD; 12 pm-3 pm in SA), with a 24 kWh daily cap. This is designed to encourage shifting energy use to periods of high solar generation, even if you don’t have your own solar panels.

Actionable Steps to Reduce Your Winter 2026 Electricity Bill
Understanding the components of your bill is the first step; taking action is the next. Here’s what you can do:
1. Compare Your Energy Plan Regularly
Most Australians are on market offers, not standing offers (DMO/VDO). While DMO/VDO rates provide a benchmark, market offers can be significantly cheaper. Retailers are not obligated to pass on DMO/VDO price cuts to market offers, so actively comparing plans is essential. Use government comparison websites like Energy Made Easy (for NSW, SE QLD, SA) or Victorian Energy Compare (for VIC) to find the best deals. Look for plans with lower daily supply charges if your usage is low, or competitive usage rates if you’re a high consumer. Some retailers offer plans 20-21% below the VDO in Victoria, such as Power House, 1st Topaz, and Everyday Easy (as of June 2026).
2. Maximise Smart Meter Benefits and Embrace Time-of-Use
If you have a smart meter, you can leverage time-of-use tariffs to your advantage. These tariffs charge different rates for electricity depending on the time of day (e.g., peak, shoulder, off-peak). By shifting high-energy activities like running your washing machine, dishwasher, or charging an EV to off-peak or the new Solar Sharer Offer free window, you can significantly reduce your costs.

3. Improve Home Energy Efficiency
Reducing overall consumption directly impacts the usage component of your bill. Winter is the time to focus on insulation and efficient heating:
- Insulation: Upgrading ceiling, wall, and floor insulation can drastically reduce heat loss, cutting heating costs. Look into state-specific rebates for insulation upgrades. For example, SA’s REPS scheme supports home insulation.
- Efficient Heating: Reverse-cycle air conditioners (heat pumps) are far more energy-efficient than traditional electric resistance heaters. If you’re using older heating, consider an upgrade. Heat pump hot water systems also offer substantial savings.

4. Consider Solar and Batteries
While an upfront investment, rooftop solar with or without a home battery can significantly offset grid reliance and reduce bills long-term. Federal incentives like Small-scale Technology Certificates (STCs) provide an upfront discount on eligible solar systems. Home batteries, supported by federal programs (around 30% off eligible batteries), allow you to store excess solar or cheap off-peak power for use during expensive peak periods.
5. Review Your Gas Usage
If you have gas heating or hot water, gas prices also contribute to your overall energy expenditure. The trend towards electrification is strong in Australia, with many households considering switching from gas to electric appliances.

Bottom Line
Your Australian electricity bills are still high in Winter 2026 primarily due to increased fixed daily supply charges and higher winter energy consumption, even as wholesale electricity prices and some usage rates decline. While federal universal energy relief has ended, state-specific concessions and new initiatives like the Solar Sharer Offer provide opportunities for savings. The most effective strategy is to proactively compare energy plans to ensure you’re on the most competitive market offer and invest in home energy efficiency measures to reduce your overall consumption. Don’t be a ‘lazy customer’ – compare, switch, and adapt your energy habits to take control of your winter bills.
