Winter 2026 is here, and with it comes the annual challenge of managing rising electricity bills. For Australian households on Time-of-Use (ToU) electricity plans, strategic energy consumption is crucial to avoid expensive peak charges. The good news is that the Default Market Offer (DMO) and Victorian Default Offer (VDO) prices, effective from 1 July 2026, show reductions in most states, particularly for those on ToU tariffs. Households in South East Queensland, for instance, could see annual savings of up to $229 on ToU plans.
This guide will equip you with the knowledge and actionable strategies to significantly reduce your winter electricity costs by optimising your usage around ToU tariffs and leveraging new offers like the Solar Sharer.
Understanding Time-of-Use Tariffs in Winter 2026
Time-of-Use tariffs divide the day into different periods, each with its own electricity rate. During winter, these periods become particularly important as heating and lighting increase household consumption. While specific times and rates vary by state, network distributor, and retailer, the general structure remains consistent:
- Peak: The most expensive period, typically in the evenings when demand is highest (e.g., 4 pm - 9 pm). This is when families return home, cook dinner, and use heating. Avoiding or minimising high-draw appliance use during these hours is paramount.
- Shoulder: Moderately priced periods, usually morning and late afternoon/early evening, before or after peak. Some retailers, like EnergyAustralia, are introducing new shoulder tariffs for residential customers on two-part ToU plans from 1 July 2026.
- Off-peak: The cheapest period, typically overnight (e.g., 10 pm - 7 am) and often extending through the middle of the day. This is your golden window for running energy-intensive appliances.
Current Electricity Price Changes (Effective 1 July 2026)
The Australian Energy Regulator (AER) and the Essential Services Commission (ESC) have released their Default Market Offer (DMO) and Victorian Default Offer (VDO) determinations for 2026-27, which act as a safety net for customers on standing offers and a reference price for market offers.
| State/Region | DMO/VDO Type | Change (Residential) | Annual Impact (Residential) |
|---|---|---|---|
| New South Wales | ToU Standing Offer | -3.7% to -7.7% | -$72 to -$211 |
| Flat Rate Standing Offer | -3.4% to -5.0% | -$66 to -$137 | |
| South East Queensland | ToU Standing Offer | -10.7% | -$229 |
| Flat Rate Standing Offer | -7.2% | -$155 | |
| South Australia | ToU Standing Offer | -1.1% | -$25 |
| Flat Rate Standing Offer | +1.4% | +$33 | |
| Victoria | VDO (all tariffs) | -3.2% to -8.4% | -$84 (average) |
| Regional Queensland | Regulated Tariffs | -6.9% (Tariff 11) | -$151 (median) |

It’s important to note that while DMO/VDO prices set a maximum, competitive market offers from retailers are often lower, sometimes up to 20% below the DMO in areas like the Energex zone in South East Queensland.
The Game Changer: Solar Sharer Offer (Winter 2026)
From 1 July 2026, a significant new initiative, the Solar Sharer Offer, is available to eligible households with smart meters in DMO regions (NSW, South Australia, and South East Queensland). This opt-in offer provides three hours of free electricity in the middle of the day, capped at 24 kWh.
- NSW & SE QLD: 11 am - 2 pm free electricity.
- South Australia: 12 pm - 3 pm free electricity.
Crucially, you do not need solar panels to benefit from this offer, and it’s available to renters. This creates an unprecedented opportunity to shift significant energy usage to a truly ‘free’ period.
“For residential customers on time-of-use tariffs, the AER’s 2026-27 DMO determination shows price decreases of up to 10.7% in South East Queensland, offering the largest residential ToU reduction nationally.”
Top Strategies for Winter 2026 ToU Savings
1. Shift High-Energy Appliance Use to Off-Peak or Solar Sharer Periods
This is the most direct way to save. Identify your biggest energy consumers and reschedule their operation:
- Washing Machines & Dishwashers: Use delay start functions to run these overnight or during the Solar Sharer window. Modern appliances are quiet enough not to disturb sleep.
- Clothes Dryers: These are energy hogs. If you must use one, run it off-peak. Better yet, utilise natural sunlight or a clothes horse during the day.
- Electric Hot Water Systems: If you have an older electric storage system, consider installing a timer to heat water only during off-peak hours. Better yet, upgrade to a heat pump hot water system, which can be programmed to run during off-peak or Solar Sharer times, dramatically reducing running costs. For more, see our guide: Heat Pump Hot Water Australia 2026: Slash Bills by $900+ with Rebates.
- Electric Vehicle (EV) Charging: Charging an EV at home can add significant load. Schedule charging to coincide with off-peak rates or the Solar Sharer period. This can slash your EV charging costs by up to $800 per year. For detailed strategies, read: Slash EV Charging Costs by Up To $800/Year: Best Electricity Plans in Australia 2026.
2. Optimise Heating with Smart Thermostats
Heating is often the largest component of winter electricity bills. Smart thermostats offer granular control and learning capabilities to minimise waste.
| Smart Thermostat Model | Key Features | Estimated Price (AUD) |
|---|---|---|
| Google Nest Learning Thermostat (4th Gen) | Learns preferences, Home/Away Assist, Eco Mode, voice control | ~$350 - $400 |
| Ecobee Smart Thermostat Premium | Voice assistant, air quality monitor, remote sensors, ‘Peak Relief’ | ~$380 - $450 |
| Sensi Touch 2 Smart Thermostat ST76 | Improved touchscreen, room sensor pairing, scheduling | ~$250 - $300 |
Prices are indicative as of July 2026 and may vary by retailer.
These devices can pre-heat your home during shoulder or off-peak periods, then maintain comfort with minimal peak-time usage. They can also integrate with your ToU plan to automatically adjust settings based on current rates.
3. Leverage Smart Meters for Real-time Insights
A smart meter is essential for any ToU plan, including the new Solar Sharer Offer. It records your electricity consumption in short intervals (e.g., 30 minutes) and sends the data directly to your retailer, enabling accurate ToU billing. More importantly, many smart meters, when paired with an in-home display or energy monitoring app, provide real-time data, allowing you to see exactly when you’re using the most expensive power.
If you don’t have a smart meter, contact your distributor or retailer to inquire about an upgrade. Many states offer incentives, and it’s a critical step to unlock ToU savings. Learn more in our dedicated guide: Unlock $800+ Savings: Your Smart Meter Guide for Australia 2026.
4. Review Your Energy Plan Annually (or More Often)
With DMO/VDO changes and new offers like the Solar Sharer, it’s never been more important to compare your current plan. Don’t assume you’re on the best deal. Use government comparison websites like Energy Made Easy (for NSW, QLD, SA, TAS, ACT) or Victorian Energy Compare (for Victoria) to find the most competitive market offers.
5. Explore State-Based Energy Bill Relief and Concessions
While the universal federal Energy Bill Relief Fund ended in December 2025, targeted state and territory concessions remain active for eligible households.
- NSW: Low Income Household Rebate (up to $285/year), Family Energy Rebate (up to $180/year), Seniors Energy Rebate ($200/year).
- Victoria: Annual Electricity Concession (17.5% off bill), Utility Relief Grants (up to $650).
- Queensland: Electricity Rebate ($386.34/year).
- South Australia: Cost of Living Concession (variable, includes energy supplement).
Check your eligibility and apply through your state government’s energy department or Service NSW. For a complete overview, consult: Navigating Australia’s Energy Bill Relief and Support in 2026: A Comprehensive Guide.
Bottom Line
Mastering Time-of-Use electricity in Winter 2026 is about more than just turning off lights; it’s about intelligent energy management. With DMO/VDO prices generally falling (except SA flat rates), and the introduction of the Solar Sharer Offer providing free midday power, there are significant opportunities to save. Your immediate actions should be to check if you have a smart meter, review your current electricity plan against market offers, and strategically shift your high-energy consumption to off-peak or the new free Solar Sharer periods. By doing so, you can effectively avoid peak charges and keep hundreds of dollars in your pocket this winter.
