How to Save Electricity and Cut Your Bills in Singapore 2026
Electricity bills in Singapore have climbed relentlessly. With tariffs hitting 32.57 cents per kWh in mid-2025 and continuing to rise, the average Singapore household now spends S$200 to S$400 per month on electricity. That is S$2,400 to S$4,800 per year disappearing from your bank account into the grid.
The good news? You can slash that bill by 50 to 80% using a combination of smart habits, efficient appliances, and solar energy. This guide covers every strategy from quick free wins to the ultimate long-term solution.
Quick Wins: Save 10 to 20% With Zero Cost
Air Conditioning Optimisation
Air conditioning accounts for 30 to 40% of a typical Singapore home's electricity consumption:
- Set temperature to 25 degrees instead of 22 to 23. Each degree below 25 increases energy use by 3 to 5%.
- Use ceiling fans with AC. Moving air feels 2 to 3 degrees cooler.
- Clean filters monthly. Dirty filters increase energy consumption by 5 to 15%.
- Use timer mode to switch off after falling asleep.
Estimated savings: S$15 to S$40 per month.
Lighting
- Switch all bulbs to LED (75% less electricity than incandescent)
- Use task lighting instead of overhead
- Install motion sensors in corridors and bathrooms
Standby Power
Electronics on standby consume 5 to 10% of total household electricity. Use power strips with switches to cut phantom loads.
Medium Wins: Save 15 to 30%
Efficient Appliances
| Appliance | Typical Consumption | 5-Tick vs 2-Tick Savings | Annual Savings |
|---|---|---|---|
| Refrigerator | S$40 to S$80/month | 30 to 40% reduction | S$144 to S$384 |
| Air conditioner | S$60 to S$160/month | 20 to 30% reduction | S$144 to S$576 |
| Washing machine | S$15 to S$30/month | 25 to 35% reduction | S$45 to S$126 |
| Clothes dryer | S$20 to S$40/month | 30 to 40% reduction | S$72 to S$192 |
Water Heater Upgrade
Switching to a heat pump water heater saves S$20 to S$50 per month. Heat pumps are 3 to 4 times more efficient than conventional electric heaters.

How Solar Savings Work With Sunollo
A typical 10 kWp Sunollo system costs S$10,000 to S$12,000 (S$1,000 to S$1,200 per kWp) and generates approximately 12,000 to 14,000 kWh per year. At the current tariff, that electricity is worth S$3,900 to S$4,560 annually. Over 25 years, a 10 kWp system saves approximately S$160,000 to S$220,000.
Sunollo's pricing includes panel-level optimisers (recovering 10 to 25% more energy on shaded roofs), SunolloCare with 25-year maintenance, monitoring, and performance guarantee, and full system insurance against weather, theft, and electrical faults.
Solar Plus Battery: Maximum Savings
Add a battery (S$5,000 to S$12,000 through Sunollo) to store excess daytime solar for evening use. This pushes bill reductions to 80 to 90%. Sunollo's Abundance Pro system includes panels with optimisers, battery, and EV charging in one integrated package with SunolloCare insurance coverage.
