For Australian homeowners, understanding and optimising electricity usage with Time-of-Use (TOU) tariffs is no longer optional; it’s a critical strategy to significantly reduce your annual power bills. By strategically shifting when you consume electricity, particularly for high-demand appliances and EV charging, you can realistically cut your costs by over $1,000 per year in 2026, especially when combined with solar and battery storage. This guide will walk you through the specifics of TOU tariffs across Australia, current pricing, and actionable steps to maximise your savings.
What Are Time-of-Use Tariffs and How Do They Work in 2026?
Time-of-Use tariffs are electricity pricing structures where the cost of electricity changes based on the time of day, week, and sometimes even the season. This system is designed to reflect the real-time cost of generating and supplying electricity to the grid, incentivising consumers to use power during periods of lower demand. As smart meters become standard across Australia, more households are transitioning to these dynamic pricing plans.
TOU tariffs typically divide the day into three main periods:
- Peak: The most expensive period, usually late afternoon and evening when demand on the National Electricity Market (NEM) is highest.
- Shoulder: Periods of moderate demand and medium pricing, often mornings and early evenings outside of peak times.
- Off-peak: The cheapest periods, typically overnight or during low-demand hours. Increasingly, some networks offer very low midday rates, dubbed ‘solar soak’ periods, to encourage consumption when rooftop solar generation is high.
It’s crucial to understand that TOU periods and rates are not standardised across Australia. They vary significantly depending on your electricity distribution network, retailer, state, and specific energy plan. Always check your electricity bill or your retailer’s Basic Product Information Document (BPID) for the exact times and rates that apply to your home.
“For smart meter households on a time of use standing offer, there are savings across all three regions [NSW, QLD, SA], from a 1.1% decrease in South Australia to up to 10.7% in South East Queensland.”
Typical 2026 Time-of-Use Periods and Rates by State
While retailers can set their own pricing windows, the underlying network tariffs provide a general framework. Here are representative examples of TOU periods and indicative rates for major networks in 2026. Remember, these are general and your specific plan may differ.
| State/Network | Period | Typical Times (e.g., Weekdays) | Indicative Retail Rate (c/kWh) |
|---|---|---|---|
| NSW (Ausgrid) | Peak | 3 PM – 9 PM (Summer/Winter) | 55 - 70 |
| Off-peak | All other times | 25 - 30 | |
| VIC (Jemena) | Peak | 4 PM – 9 PM | 30 - 45 |
| Solar Soak | 11 AM – 4 PM | 1 - 15 | |
| Off-peak | All other times | 18 - 25 | |
| QLD (Energex) | Peak | 4 PM – 9 PM | 45 - 60 |
| Daytime Off-peak | 11 AM – 4 PM | 7 - 20 | |
| Shoulder | 9 PM – 11 AM (next day) | 25 - 35 | |
| SA (SA Power Networks) | Peak | 6 AM – 10 AM & 4 PM – 12 AM | 40 - 55 |
| Off-peak | 12 AM – 6 AM | 15 - 25 |
Note: Retailer rates include network charges, wholesale costs, and retail margins. Network charges for Ausgrid’s residential TOU are around 32.52 c/kWh (peak) and 5.36 c/kWh (off-peak). Energex’s DMO TOU cap for 2026-27 shows a range from 6.98c/kWh (daytime off-peak) to 47.79c/kWh (peak). Jemena’s network rates include a solar soak period at 1.000 c/kWh. These figures are current as of mid-2026 and are subject to change.
Strategies to Optimise Your Electricity Usage and Save
1. Shift High-Drain Appliance Usage
The most straightforward way to save is to reschedule when you run energy-intensive appliances. This simple shift can yield substantial savings.
- Washing Machines & Dishwashers: Run these overnight (10 PM – 7 AM) or during midday off-peak/solar soak periods. Many modern appliances feature delay timers, allowing you to load them and set them to start automatically during cheaper hours.
- Electric Hot Water Systems: If you have a dedicated off-peak hot water system, ensure its timer is correctly set to heat water only during off-peak times. For continuous systems, consider a smart timer or load controller.
- Pool Pumps: Program your pool pump to operate during off-peak or shoulder periods, particularly overnight. A typical pool pump can consume 1-2 kWh per hour, making its runtime a significant cost factor on peak rates.
- Air Conditioning: Pre-cool your home during shoulder periods before the peak rates kick in. Smart thermostats, such as the Ecobee Smart Thermostat Premium (around $350), can learn your schedule and optimise cooling based on TOU prices.
2. Integrate Solar PV for Daytime Savings
Rooftop solar is a powerful tool against high daytime electricity costs, especially during shoulder periods. By generating your own power, you reduce reliance on the grid when rates are moderate.
- Self-Consumption: Maximise the use of your generated solar power by running appliances like dishwashers, washing machines, and pool pumps during the middle of the day when your panels are producing the most electricity. This offsets consumption that would otherwise be charged at shoulder rates (typically $0.25–$0.35/kWh).
- Declining Feed-in Tariffs (FiT): With FiTs continuing to decline (e.g., Momentum Energy’s NSW FiT decreased from 5c/kWh to 3c/kWh from July 1, 2026), self-consumption is far more financially beneficial than exporting excess power.
A standard 6.6kW solar system costs between $5,000 and $8,500 installed in 2026 after rebates, offering long-term savings. For more detailed information, read our guide: Solar System Installation Costs in Australia 2026: A Complete Guide.
3. Add Home Battery Storage for Peak Shaving
Home batteries are the ultimate TOU optimisation tool, allowing you to store cheap off-peak grid electricity or excess solar generation and use it during expensive peak periods.
- Charge when Cheap, Discharge when Dear: Program your battery to charge from the grid during off-peak hours (e.g., 10 PM – 7 AM) or from your solar panels during the day. Then, discharge the stored energy to power your home during the peak evening rates (e.g., 3 PM – 9 PM). This can save you $0.40–$0.55 per kWh that would otherwise be imported at peak rates.
- Federal Rebates: The Federal Cheaper Home Batteries Program provides a significant discount, typically around 30% off the upfront cost. As of mid-2026, this translates to approximately $252 per usable kWh, meaning a 13.5 kWh system could receive around $3,400 in federal rebates. This rebate is applied at the point of sale by accredited installers and can often be stacked with state-specific incentives.
Here’s an overview of popular home battery systems and their approximate installed costs (before state rebates):
| Battery System | Usable Capacity (kWh) | Approx. Installed Cost (AUD) |
|---|---|---|
| Alpha ESS SMILE5 | 5.1 | $7,000 - $9,500 |
| Sungrow SBR | 9.6 | $10,000 - $13,000 |
| Tesla Powerwall 3 | 13.5 | $12,000 - $17,000 |
| BYD Battery-Box Premium | 10.2 | $11,000 - $14,500 |

4. Smart EV Charging for Maximum Savings
Electric Vehicles (EVs) have large batteries that can significantly increase your household electricity consumption. Charging your EV during off-peak periods is one of the most impactful ways to save.
- Scheduled Charging: Use your EV’s in-built scheduling function or a smart home EV charger like the Wallbox Pulsar Plus (around $1,200 - $1,600 installed) to automatically charge your vehicle during off-peak hours, typically overnight.
- Cost Comparison: Charging a typical 60 kWh EV battery from 10% to 100% on a standard residential rate (approx. 30 c/kWh) costs around $17.82, or $4-5 per 100km. However, charging on an off-peak EV plan (approx. 8-18 c/kWh) can drop the cost to as low as $1-2 per 100km.
- Solar Integration: If you have solar, charge your EV during the day to utilise free solar energy. This can reduce your charging costs to near zero for the kWh you would otherwise export.

5. Utilise Home Energy Management Systems (HEMS)
A HEMS acts as the brain of your home’s energy ecosystem, automating your usage to respond to TOU pricing and optimising your solar and battery performance. Systems like Amber Electric’s Dynamic Pricing or Reposit Power can integrate with smart meters, batteries, and appliances to automatically shift loads or export power when prices are highest.
While specific HEMS product prices vary, many modern inverters (e.g., Fronius Symo Hybrid, SolarEdge Energy Hub) come with integrated energy management capabilities, or you can add dedicated systems like the SMA Home Manager 2.0 (around $1,000 - $1,500 installed).

6. Participate in Virtual Power Plants (VPPs)
If you have a home battery, joining a Virtual Power Plant (VPP) can unlock additional revenue streams. VPPs aggregate distributed home batteries to provide services to the grid, like frequency control and demand response, especially crucial as coal-fired generation retires.
- Earn Revenue: VPPs can pay you for allowing your battery to discharge electricity back to the grid during periods of high demand or grid stress. This can be particularly lucrative during peak pricing events. Programs typically offer annual incentives or payments per kWh dispatched. For instance, some VPPs offer $200 - $600+ annually for a 10 kWh battery.

The Broader Grid Context: Why TOU Matters
The Australian Energy Market Operator (AEMO) plays a critical role in managing the National Electricity Market (NEM), which is undergoing a rapid transformation. The 2026 Integrated System Plan (ISP) highlights a shift towards a system built around renewable energy, firmed with storage, as ageing coal-fired power stations retire.
This transition means increased reliance on consumer energy resources (CER) like rooftop solar, home batteries, and EVs to support grid stability and reliability. TOU tariffs are a key mechanism to manage demand, encouraging consumers to be part of the solution by reducing peak load and utilising abundant solar generation.
