Australians can significantly reduce their electricity bills by hundreds, potentially over $800 annually, by understanding and optimising their energy use around Time-of-Use (ToU) tariffs and adopting smart consumption strategies in 2026. This involves shifting high-demand activities to off-peak periods and leveraging technologies like smart meters and home batteries. With new regulated offers, including a ‘3 Hours Free Electricity’ initiative starting July 1, 2026, the opportunity for savings is greater than ever.
Understanding Time-of-Use (ToU) Tariffs in 2026
ToU tariffs charge different rates for electricity depending on the time of day, reflecting the wholesale cost of power. These tariffs are structured into three main periods:
- Peak: The most expensive period, typically late afternoon and evening on weekdays when demand from homes and businesses is highest (e.g., 2 pm to 8 pm or 4 pm to 9 pm).
- Shoulder: Intermediate periods, such as mid-morning, early afternoon, early evening, and often most of the weekend, with moderate demand and prices.
- Off-Peak: The cheapest period, usually overnight (e.g., 10 pm to 7 am) and often during the middle of the day (11 am to 4 pm), when demand is lowest and renewable generation (like solar) is abundant.
To benefit from ToU tariffs, you need a smart meter, which records your electricity consumption in 30-minute intervals. Most retailers will install one for free if you don’t already have one. If you’re on a flat-rate tariff, switching to a ToU plan can be beneficial if you can actively manage your consumption times.

The New ‘Solar Sharer Offer’: 3 Hours Free Power Daily
From July 1, 2026, a significant new initiative, often called the ‘Solar Sharer Offer’ or ‘3 Hours Free Electricity’, is rolling out in NSW, South East Queensland, and South Australia for eligible households with smart meters. This regulated offer provides three hours of free electricity usage daily, capped at 24 kWh, during the middle of the day when solar generation is at its peak.
This free window is fixed year-round, typically:
- NSW (Ausgrid, Endeavour, Essential networks): 11 am – 2 pm
- South East Queensland (Energex network): 11 am – 2 pm
- South Australia (SA Power Networks): 12 pm – 3 pm
Retailers like Origin are offering this via their ‘Origin Standing Solar Sharer’ plan, and OVO Energy has a ‘Free 3 Plan’ with an 11 am-2 pm free window. This presents a substantial opportunity to run high-energy appliances like dishwashers, washing machines, and even charge electric vehicles without usage charges during these times.
State-by-State Electricity Price Landscape (2026)
The Default Market Offer (DMO) and Victorian Default Offer (VDO) set a safety net price for standing offers and act as a benchmark for market offers. These prices, effective from July 1, 2026, show varied movements across states, as determined by the Australian Energy Regulator (AER) and Essential Services Commission (ESC) Victoria:
| State/Region | Residential Flat Rate DMO/VDO Change (2026-27) | Residential Time-of-Use DMO Change (2026-27) | Average Annual Bill (Flat Rate) | Typical Peak Times (Example) |
|---|---|---|---|---|
| NSW | Decreased 3.4% to 5.0% | Decreased 3.7% to 7.7% | $1,875 - $2,515 | 3 pm – 9 pm (seasonal) |
| Victoria | Decreased average 5.0% ($84/year) | New 3-period ToU with solar soak | $1,481 - $1,748 (average $1,591) | 3 pm – 9 pm (general) |
| SE Queensland | Decreased 7.2% ($155) | Decreased 10.7% ($229) | -$155 (reduction) | 4 pm – 9 pm |
| South Australia | Increased 1.4% ($33) | Decreased 1.1% ($25) | +$33 (increase) | 4 pm – 9 pm (general) |
| ACT | No DMO, regulated offers | Peak 7 am-9 am & 5 pm-8 pm | Varies | 7 am-9 am & 5 pm-8 pm |
| Western Australia | Not in NEM, Synergy regulated | Super off-peak 9 am-3 pm (Synergy) | Varies | 4 pm – 9 pm (general) |
| Tasmania | Regulated prices | Varies | Varies | 4 pm – 9 pm (general) |
| Northern Territory | Not in NEM, Jacana Energy regulated | Off-peak 9 am-3 pm | Varies | 3 pm – 9 am (all other times) |
Wholesale electricity spot prices across the National Electricity Market (NEM) averaged $73/MWh in Q1 2026, a 12% drop year-on-year. However, South Australia saw a 33% increase to $88/MWh, experiencing price spikes up to $19,000/MWh during extreme demand events, according to AEMO data.
These DMO/VDO figures highlight the importance of comparing market offers, as they can often be significantly cheaper than standing offers. Use government comparison tools like Energy Made Easy (for NSW, QLD, SA, ACT, TAS) and Victorian Energy Compare to find the best plan for your consumption patterns.
Smart Consumption Strategies to Maximise Savings
Leveraging ToU tariffs requires conscious effort or smart technology to shift your energy use. Here’s how:
1. Automating Appliances
Use smart plugs and timers to schedule high-energy appliances like washing machines, dishwashers, and pool pumps to run during off-peak or free electricity windows. Many modern appliances also have built-in delay start functions.
2. Smart EV Charging
Electric Vehicle (EV) owners can achieve substantial savings, potentially up to $1,000 per year, by utilising dedicated EV electricity plans. These plans often offer ultra-low rates or even free electricity during overnight off-peak periods or mid-day solar soak windows. For example, Engie’s EV Night Saver offers 6c/kWh from 12 am-6 am, while OVO Energy’s The EV Plan includes free electricity from 11 am-2 pm.
Consider linking your EV charger to a smart home energy management system to automatically optimise charging based on your tariff and solar generation. For more details, see our guide: Slash EV Charging Costs by Up To $800/Year: Best Electricity Plans in Australia 2026
3. Home Battery Storage
Installing a home battery system allows you to store excess solar generation during the day or cheap off-peak grid electricity, then discharge it during expensive peak periods. This “arbitrage” of electricity prices can significantly reduce your reliance on the grid at its most expensive times.
Federal Cheaper Home Batteries Program (2026): This expanded program offers a discount of around 30% off the upfront cost of eligible battery systems (5 kWh to 50 kWh). For a 13.5 kWh battery, the federal rebate is approximately $3,367 to $3,705. This rebate is set to decrease every six months, with the next cut on January 1, 2027, so acting sooner can secure a higher discount.
State-Specific Battery Incentives: Many states offer additional support that can be stacked with the federal rebate:
- NSW: Up to an additional $1,500 for connecting to a Virtual Power Plant (VPP) through schemes like the Empowering Homes program.
- WA: Residential Battery Scheme offers up to $5,000 (Synergy customers) or $7,500 (Horizon Power customers) for the first 10 kWh, requiring VPP enrolment. Interest-free loans up to $10,000 are also available through the Clean Energy Future Fund.
- ACT: Interest-free loans up to $15,000 through the Sustainable Household Scheme for battery installations.
Popular Home Battery Systems & Costs (2026 - Estimated Installed, after Federal Rebate):
| Battery Model | Usable Capacity (kWh) | Estimated Installed Price (AUD) | Key Features |
|---|---|---|---|
| Sungrow SBR | 9.6 - 25.6 | From $7,999 | Modular, expandable, good value, ideal for existing Sungrow solar systems |
| SonnenBatterie | 5 - 15 | $9,375 (6kWh) - $15,175 (14kWh) | German-engineered, local Adelaide manufacturing, predictive charging |
| Tesla Powerwall 3 | 13.5 | $12,500 - $14,500 | All-in-one with integrated inverter, 11.04kW continuous output, Tesla app integration |
For a typical household using 20 kWh/day on a 45c/kWh peak rate, a 15 kWh battery could deliver annual savings of around $2,000, with a payback period of approximately 5 years after rebates.
