2025 Australia Electricity Bills: New Tariffs, Peak/Off-Peak Costs & Real Savings
Electricity bills across Australia continue to rise as networks update tariffs, adjust peak and off-peak rates, and introduce new demand-based charges. Many households are unsure whether they’re paying the correct tariff or missing out on potential bill savings. Understanding the updated 2025 electricity pricing structure can prevent unnecessary household spending and help you switch to a more efficient plan. Start by reviewing your current tariff and comparing it with your distributor’s 2025 updates.
Why Electricity Tariffs Are Changing in 2025
Australia’s electricity distributors have updated tariffs to manage growing demand, rooftop solar exports, and grid reliability. These changes include revised peak hours, higher supply charges in some regions, and expanded time-of-use (TOU) options. For households, this means electricity cost calculations in 2025 may look different compared to previous years.
2025 Electricity Tariff Types Explained
1. Time-of-Use (TOU) Tariffs
TOU tariffs charge different rates depending on when you use electricity. The 2025 update places stronger emphasis on reducing peak demand.
- Peak: Highest price — typically weekday afternoons/evenings.
- Shoulder: Medium price — late mornings, early evenings.
- Off-Peak: Lowest price — usually overnight.
Households using a lot of electricity at night (heating, EV charging, hot water systems) may save significantly on TOU tariffs.
2. Single-Rate Tariffs
This tariff charges the same price 24/7. It remains popular for households with consistent power usage. In 2025, single-rate tariffs increased in most states due to rising wholesale prices.
3. Demand Tariffs
Demand tariffs charge households based on their highest 30-minute usage window within the billing cycle. These are expanding across NSW, VIC, SA and QLD in 2025 due to smart meter rollout.
2025 Peak & Off-Peak Cost Trends by State
New South Wales (NSW)
NSW networks are increasing daily supply charges, while peak rates remain the highest on the east coast. Off-peak pricing offers strong savings for overnight use.
Victoria (VIC)
VIC maintains some of the lowest off-peak rates nationally, but demand tariffs are becoming more common. Smart meter penetration allows detailed billing.
Queensland (QLD)
QLD peak rates increased moderately in 2025, with TOU incentives aimed at shifting evening household loads. Off-peak continues to be favourable for EV charging.
Western Australia, SA, Tasmania, ACT, NT
Most states maintain state-regulated pricing, but off-peak reductions vary. SA and TAS benefit the most from overnight rate discounts.
How to Save on Your 2025 Electricity Bill
- Shift heavy loads (dishwasher, laundry, EV charging) to off-peak hours.
- Check if your retailer offers a cheaper TOU plan — many default plans are outdated.
- Review your daily supply charge — this often increases faster than usage rates.
- Use a smart meter to track high-load periods and avoid peak spikes.
- Consider a controlled-load tariff for electric hot water systems.
Quick Comparison: 2025 Peak vs Off-Peak Usage
| State | Peak Cost Trend | Off-Peak Cost Trend | Best Savings Strategy |
|---|---|---|---|
| NSW | High | Low | Shift major loads to overnight |
| VIC | Moderate | Very Low | TOU + controlled load |
| QLD | Moderate | Low | EV charging off-peak |
| SA/TAS | High | Low | Timer-based appliances |
Before You Adjust Your Plan
Before switching electricity plans, review your historical usage patterns. If your home consumes the most electricity during peak windows, switching to TOU may increase your bill. Conversely, households with flexible usage can save significantly in 2025 by moving to off-peak-friendly tariffs. Always compare retailers and check if the daily supply charge offsets your savings.
