Winter 2026 is here, and with the direct federal energy bill relief payments from 2025 now concluded, many Australian households are looking for new strategies to manage their electricity costs. While the direct federal handouts are no longer available, there’s good news: the Australian Energy Regulator (AER) has proposed Default Market Offer (DMO) reductions for New South Wales, South East Queensland, and South Australia from 1 July 2026, driven largely by lower wholesale electricity costs. This means that for many, the ‘safety net’ price for electricity could decrease, offering some reprieve.
However, relying solely on DMO changes is not a comprehensive strategy. Proactive measures, from optimising your energy usage to investing in efficiency upgrades and renewables, are essential to significantly reduce your winter electricity bill in 2026.
1. Understand Your Energy Plan and Switch Retailers
Your current electricity plan is the first place to look for savings. Many Australians remain on standing offers that are often more expensive than competitive market offers. The AER’s DMO serves as a benchmark for comparison in NSW, South East Queensland, and South Australia. Always compare your current plan against the DMO and other market offers.
The AER’s draft DMO for 2026-27 proposes residential price decreases ranging from 1.3% (-$31 annually) in South Australia to 10.1% (-$216 annually) in South East Queensland (Energex network) and up to 8.2% (-$226 annually) in NSW (Essential Energy network).
Consider retailers like Amber Electric, which offer wholesale-linked pricing plus a flat monthly subscription fee (e.g., around $22 per month). This model can be highly beneficial for households with solar panels, batteries, or those who can shift their energy consumption to periods of lower wholesale prices. Amber provides an app with a 12-hour price forecast and live price tracker, allowing you to run high-demand appliances when electricity is cheapest, or even when prices are negative. They operate in NSW, Victoria, SA, ACT, and South East Queensland.
| Retailer Offer Type | Description | Potential Benefit |
|---|---|---|
| Default Market Offer (DMO) | Government-regulated price cap for standing offers. | Safety net, proposed reductions from July 2026 in NSW, SE QLD, SA. |
| Market Offers | Competitive plans from retailers, often with discounts. | Can be significantly cheaper than DMO; requires active comparison. |
| Wholesale-Linked (e.g., Amber Electric) | Pass-through of live wholesale prices + flat fee. | Maximise savings with solar/batteries and flexible usage habits. |

2. Embrace Energy Efficiency Upgrades
Reducing the amount of electricity your home consumes is a foundational step. Winter heating is typically the largest electricity drain for Australian households.
Efficient Heating
- Reverse Cycle Air Conditioners: These are among the most energy-efficient heating options, operating by moving heat rather than generating it. Ensure your unit is serviced annually for optimal performance.
- Smart Thermostats: Installing a smart thermostat allows for precise temperature control and scheduling, preventing unnecessary heating. Products like the Ecobee Smart Thermostat Premium or Google Nest Thermostat learn your habits and can be controlled remotely. Expect costs between $200 and $400 for a quality unit, plus installation if required. For more information, read: Best Smart Thermostats in Australia 2026: Cut Your Winter Heating & Cooling Costs.
Hot Water Systems
Hot water accounts for a significant portion of household energy use. Switching from an electric storage or gas hot water system to a heat pump hot water system offers substantial savings.
- Costs & Savings: A heat pump hot water system costs, on average, $4,527 nationally (installed, with federal STCs) in April 2026. Running costs are typically $150 to $300 per year, about a third of an old electric storage tank. Over 10 years, a heat pump could cost around $4,800 total, compared to $6,500-$7,200 for gas systems.
- Rebates: Federal Small-scale Technology Certificates (STCs) currently provide approximately $600-$900 off the upfront cost of a heat pump in 2026. State-specific rebates can further reduce this. For example, in Victoria or NSW, combined federal and state rebates can bring the out-of-pocket cost down to $2,667 to $4,073.
Insulation and Draught Sealing
Proper insulation in ceilings, walls, and floors, along with sealing draughts around windows and doors, can drastically reduce heat loss. Victoria’s VEU program is expanding to include ceiling insulation rebates for all eligible residential homes from 1 October 2026. The ACT’s Sustainable Household Scheme also offers low-interest loans for insulation.
3. Harness Solar Power and Battery Storage
Even in winter, solar panels can offset a portion of your daytime electricity needs. Combining solar with a home battery allows you to store excess generation for use during peak evening hours or overnight, significantly reducing your reliance on expensive grid electricity.
- Solar Panel Costs: A typical 10kW solar system averages around $10,000 fully installed in Australia, after the federal STC rebate is applied.
- Battery Costs & Rebates: The average installed price for a 10kWh home battery system is projected to be between $9,000 and $15,000 before rebates in 2026. The federal Cheaper Home Batteries Program continues but has changed from 1 May 2026. The rebate value has reduced from approximately $300-$311 per kWh to $244-$252 per kWh and is now tiered: 100% for the first 14 kWh, 60% for capacity between 14-28 kWh, and 15% for 28-50 kWh.
| Battery Capacity (kWh) | Estimated Federal Rebate (Post-May 2026) | Example Battery Models |
|---|---|---|
| 10 kWh | ~$2,440 - $2,520 | Tesla Powerwall 2 (13.5kWh), LG Chem RESU10 |
| 14 kWh | ~$3,416 - $3,528 | Tesla Powerwall 2 (13.5kWh) |
| 20 kWh | ~$4,392 - $4,536 (14kWh at 100%, 6kWh at 60%) | SonnenBatterie Hybrid 9.53 (9.5kWh modules) |
| 30 kWh | ~$5,368 - $5,544 (14kWh at 100%, 14kWh at 60%, 2kWh at 15%) | AlphaESS SMILE5 (modular) |
Note: These are estimates based on the stated rebate changes and current STC values. Actual rebate amounts will vary based on system specifics and installer pricing.
Beyond the federal scheme, some states offer additional incentives. New South Wales provides a solar battery rebate of $1,600 to $2,400 via its Peak Demand Reduction Scheme (PDRS). Western Australia’s Distributed Energy Buyback Scheme (DEBS) rewards households for exporting solar during late-afternoon peak periods.

4. Leverage Smart Meters and Time-of-Use Tariffs
Smart meters are being rolled out across NSW, ACT, QLD, and SA, with a goal for universal replacement by November 2030. Victoria already has near-universal smart meter uptake. These meters allow for remote reading and, increasingly, access to real-time energy usage data, which is crucial for managing costs.
With a smart meter, you can take advantage of Time-of-Use (TOU) tariffs, where electricity prices vary throughout the day. Typically, off-peak rates (late night/early morning) are significantly cheaper than peak rates (early evening). By shifting high-consumption activities like running your washing machine, dishwasher, or charging an electric vehicle to off-peak periods, you can realise substantial savings.

5. Behavioural Changes and Energy Audit
Simple changes in daily habits can collectively make a difference:
- Lower Thermostat Settings: Every degree you lower your thermostat can reduce heating costs by about 10%. Aim for comfortable but not excessive indoor temperatures, typically 18-20°C.
- Turn Off Lights and Appliances: Switch off lights when leaving a room and unplug electronics at the power point to eliminate ‘vampire’ power draw.
- Maximise Natural Light and Heat: Open curtains and blinds on sunny days to let in warmth, closing them as the sun sets to retain heat.
- Short Showers: Hot water is a major energy consumer. Reducing shower times saves both electricity (for heating water) and water bills.
Consider a professional home energy audit. An auditor can identify specific areas of heat loss and recommend tailored improvements for your property.
6. State-Specific Concessions and Assistance
While federal energy bill relief payments have ended, state and territory governments continue to offer various concessions and rebates for eligible households, particularly those with concession cards.
| State/Territory | Key Concessions/Rebates (2026) | Eligibility Notes |
|---|---|---|
| New South Wales | Energy Savings Scheme (discounts on efficiency upgrades), Peak Demand Reduction Scheme (battery rebates). | Concession card holders for general assistance. PDRS for battery installations. |
