For many Australian households, electricity bills feel like a fixed cost, but in 2026, mastering Time-of-Use (ToU) tariffs offers a proven path to significant savings, potentially cutting your annual bill by hundreds of dollars. By understanding and strategically shifting when you consume electricity, you can leverage cheaper off-peak rates and avoid costly peak periods, saving an average of $250 to $500 annually for a typical household, with even greater savings for those with solar and batteries.
Time-of-Use tariffs divide the day into different pricing periods: peak, shoulder, and off-peak. The price you pay per kilowatt-hour (kWh) varies drastically between these periods, reflecting the demand on the electricity grid. As Australia’s energy grid continues its transition towards renewables, these tariffs are becoming more common and sophisticated, rewarding consumers who adapt their usage patterns.
Understanding Australia’s 2026 Time-of-Use Landscape
The Australian energy market is dynamic, with the Australian Energy Regulator (AER) setting the Default Market Offer (DMO) for New South Wales, South East Queensland, and South Australia, and the Essential Services Commission (ESC) setting the Victorian Default Offer (VDO). These offers act as a safety net for customers on standing offers and a reference price for market offers. From 1 July 2026, both the DMO and VDO have seen significant updates, including regulated ToU tariffs and new ‘solar soak’ periods designed to encourage daytime usage.
“For smart meter households on a time of use standing offer, there are savings across all three DMO regions (NSW, SE QLD, SA), from a 1.1% decrease in South Australia to up to 10.7% in South East Queensland.”
Key Tariff Changes for 2026:
- DMO Regions (NSW, SE QLD, SA): The AER’s final DMO determination for 2026–27 confirms regulated ToU tariffs are now explicitly included, offering savings for smart meter households. A significant new feature is the Solar Sharer Offer (SSO), available from 1 July 2026. This offers 3 hours of free power daily in the middle of the day (typically 10 am - 1 pm or similar, varying by retailer/network) for smart meter households, regardless of whether they have solar panels. This can provide up to 24 kWh of free electricity per day, a substantial benefit for shifting daytime usage.
- Victoria: The VDO for 2026–27, effective from 1 July 2026, introduces a new three-period ToU tariff structure, often called the ‘Smart Rate’. This includes a discounted midday ‘solar soak’ period (typically 11 am – 4 pm daily), a shorter evening peak (4 pm – 9 pm), and off-peak at all other times. This aims to encourage consumption during periods of high solar generation.
Typical Time-of-Use Periods (Generalised for 2026):
While exact times vary by network distributor and retailer, here are common windows:
| Period | NSW (Ausgrid/Retailer Example) | VIC (CitiPower/Powercor - Smart Rate) | QLD (Energex - Retailer Example) | SA (SA Power Networks) |
|---|---|---|---|---|
| Peak | 2pm-8pm weekdays (Summer), 5pm-9pm weekdays (Winter) | 4pm-9pm daily | 4pm-9pm daily | 6am-10am & 3pm-1am daily |
| Shoulder | 7am-2pm & 8pm-10pm weekdays (Summer), 7am-5pm & 9pm-10pm weekdays (Winter) | N/A (merged into Off-Peak/Smart Rate) | 9pm-11am daily (excluding Solar Soak) | 10am-3pm daily |
| Off-Peak | 10pm-7am daily | 9pm-11am daily | N/A (varies by retailer, often includes weekends) | 1am-6am daily |
| Solar Soak / Smart Rate | N/A (Solar Sharer Offer applies) | 11am-4pm daily (Lowest Rate) | 11am-4pm daily (Lowest Rate) | N/A (Shoulder acts as mid-day discount) |
Note: These are general guidelines. Always check your specific electricity bill or retailer’s Basic Plan Information Document (BPID) for the exact times and rates applicable to your address and plan. Retailers may set their own specific peak windows within network guidelines.
Current 2026 Time-of-Use Electricity Prices (Indicative)
Retailer market offers typically beat the DMO/VDO. Here are indicative rates based on DMO/VDO for 2026-27, with examples of market offer ranges:
| State/Network | Period | Indicative Rate (c/kWh) | Notes Retail application is a process where individuals can apply to receive services or resources from a retailer. This might involve setting up a new account, upgrading an existing service, or purchasing a product that requires a formal application process. The information gathered during this application helps the retailer to verify identity, assess eligibility, and ensure compliance with regulatory requirements. The application may collect personal details, contact information, and financial data as needed. The specific details collected and the overall process vary depending on the retailer and the type of service or product being applied for.
Daily Supply Charge
Beyond usage rates, you’ll also pay a daily supply charge, a fixed fee for being connected to the grid. This varies by state and network, typically ranging from 80 cents to $1.50 per day.
Strategies to Optimise Your Electricity Usage and Cut Bills
The core principle of mastering ToU tariffs is simple: use more electricity during off-peak and shoulder periods, and less during peak times.
-
Shift High-Consumption Activities:
- Laundry & Dishwashing: Run your washing machine, dryer, and dishwasher overnight or during the midday solar soak/off-peak periods. A typical dishwasher uses around 1.5 kWh per cycle, costing approximately $1.05 during peak (70c/kWh) versus $0.30 during off-peak (20c/kWh).
- Electric Vehicle (EV) Charging: If you own an EV, charging it during off-peak hours is crucial. A 7kW home charger like the myenergi Zappi V2.1 (approx. $1,350 supply) or Tesla Wall Connector Gen 3 (approx. $750 supply) can be programmed to charge when rates are lowest. Charging a Tesla Model 3 (approx. 60 kWh battery) during off-peak could cost around $12.00 compared to $42.00 during peak, saving you $30 per charge.

- Hot Water Systems: If you have an electric hot water system with a controlled load tariff, ensure its timer is set to heat water during off-peak times.
-
Leverage Smart Technology:
- Smart Appliances: Many modern appliances, from washing machines to air conditioners, come with smart features that allow you to schedule their operation. Utilise these to align with cheaper tariff periods.
- Home Batteries: For solar households, a home battery system is a game-changer. Charge your battery with excess solar during the day, or from the grid during off-peak times (e.g., overnight at 20c/kWh), then discharge it during expensive peak periods (e.g., 70c/kWh). Popular models like the Tesla Powerwall 3 (approx. $14,850 - $17,000 installed, pre-rebate) or Sungrow SBR HV (approx. $9,500 for 12.8 kWh, pre-rebate) can deliver significant savings. The federal Cheaper Home Batteries Program offers rebates of around 30% off the upfront cost for eligible systems up to 50 kWh, with changes implemented from 1 May 2026.

- Virtual Power Plants (VPPs): If you have a home battery, joining a VPP can earn you additional income by allowing your battery to support the grid during peak demand events. South Australia remains a leader in VPP integration, often providing extra cash rebates or tariff discounts. See: Maximise Your Home Battery Savings: Earn $1,000+ Annually with a VPP in 2026.
- Home Energy Management Systems (HEMS): These systems automate energy usage, making real-time decisions to optimise consumption based on ToU rates, solar generation, and battery charge levels. This can slash bills by over $1,000 annually. Explore: Best Home Energy Management Systems in Australia 2026: Slash Bills by $1,000+ Annually.

Solar PV Optimisation:
- If you have solar panels, maximise self-consumption during the day. Run appliances when your panels are generating electricity. Any excess solar can be exported to the grid, often earning a feed-in tariff (FiT). Some retailers offer higher FiTs during shoulder or peak periods, making smart export strategies valuable.
Choosing the Right ToU Plan and Retailer
- Review Your Bill: Understand your current consumption patterns. Do you use a lot of power in the evenings? Are you home during the day?
- Compare Offers: Use government comparison websites: Energy Made Easy for NSW, QLD, SA, TAS, ACT, and Victorian Energy Compare for Victoria. These platforms allow you to input your actual usage data and compare plans from different retailers, including their ToU structures and rates.
- Consider Your Lifestyle: If you can consistently shift your usage to off-peak, a ToU plan is likely beneficial. If your household has high, unavoidable peak demand (e.g., evening air conditioning, cooking), a flat rate might still be better, though the new DMO/VDO ToU structures are designed to offer savings for more households.
- Check for Solar Sharer/Smart Rate Eligibility: If you have a smart meter, actively inquire about the Solar Sharer Offer in DMO regions or the Smart Rate in Victoria, as these new tariffs are specifically designed to reward daytime usage.
Energy Bill Relief in 2026
It’s important to note that the universal federal Energy Bill Relief Fund ended on 31 December 2025. However, state and territory governments continue to offer targeted concession programs for eligible households (e.g., pensioners, low-income earners, concession card holders). For example, NSW offers the Low Income Household Rebate (up to $285/year) and the Seniors Energy Rebate ($200/year). The ACT’s Electricity, Gas and Water Rebate is worth $800 a year for eligible concession card holders in 2026-27. Always check your state government’s energy department website for current eligibility.
