How to Save on Your Electricity Bill
Combine these strategies to cut your annual electricity costs by $500-1,200/year.
1. Switch Providers First
Single biggest saving — $200-400/year with one 5-minute signup. Standing offers cost 15-30% more. If you haven't switched in 2+ years, you're overpaying.
2. Use Time-of-Use Wisely
Shift heavy loads to off-peak (10pm-7am). Off-peak rates 50-70% cheaper. Most appliances have delay-start timers.
3. Heating & Cooling (40% of Bill)
Set aircon to 24°C summer / 18°C winter. Each degree outside range adds ~10% cost. Ceiling fans use 1/10th the power.
4. LED Lights
Replace 10 halogens with LEDs saves $100-150/year. Pays for itself in 6-12 months.
5. Solar: The Big One
6.6kW system: $4,000-6,000 after rebates, saves $900-1,500/year. Payback in 3-5 years. STC rebates decrease yearly — sooner is better.
6. Battery Storage
Tesla Powerwall etc: $8,000-14,000. Payback 7-10 years. Best with solar+time-of-use+high evening usage. NSW interest-free loans, VIC $2,950 rebate.
