If your latest SP Group bill made you do a double take, you're not alone. Electricity tariffs in Singapore have been on an upward trend, driven by global energy market volatility and geopolitical tensions. For the average household, this means higher monthly costs that can really add up. But don't despair — there are concrete steps you can take to bring those numbers down.

1. Switch to an Open Electricity Market Retailer

If you haven't already switched from the regulated tariff to an Open Electricity Market (OEM) retailer, now's the time to seriously consider it. OEM retailers often offer rates that are lower than the SP Group regulated tariff, and you can choose between fixed-rate and discount-off-tariff plans.

Fixed-rate plans lock in a per-kWh price for the duration of your contract, shielding you from tariff increases. Discount-off-tariff plans give you a percentage discount off whatever the current regulated rate is. In the current climate, fixed-rate plans may offer better peace of mind, but do compare the numbers before committing.

2. Optimise Your Air Conditioning

Air conditioning is the single biggest electricity consumer in most Singapore homes, accounting for roughly 30% to 40% of your total bill. Small changes here make a big difference.

Set your aircon to 25 degrees Celsius instead of 22 or 23. Every degree lower increases energy consumption by about 7% to 10%. Use the timer function to avoid running it all night — two to three hours is often enough to cool your room for comfortable sleep. And keep your filters clean; a clogged filter forces the unit to work harder, using more electricity.

3. Upgrade to Energy-Efficient Appliances

When it's time to replace an appliance, look for the NEA Energy Label. Appliances rated 4 or 5 ticks are significantly more efficient than older models. A 5-tick refrigerator, for example, can save you $50 to $80 per year compared to a 1-tick model. Over the lifespan of the appliance, that adds up to hundreds of dollars.

Inverter technology in aircon units and washing machines is particularly worth the investment. These appliances adjust their motor speed based on demand rather than running at full blast all the time, resulting in substantial energy savings.

4. Be Smart About Lighting

If you're still using incandescent or CFL bulbs, switch to LED. LED bulbs use up to 80% less electricity and last significantly longer. For a typical 3-room flat, switching all lights to LED can save $20 to $40 per year. It's one of the easiest and cheapest upgrades you can make.

Also, make it a habit to switch off lights in unoccupied rooms. It sounds obvious, but the cumulative effect of leaving lights on throughout the house is real.

5. Unplug Standby Appliances

That TV on standby, the phone charger plugged in with no phone attached, the microwave with its clock display — they're all consuming electricity even when not in active use. This "phantom load" or "vampire power" can account for 5% to 10% of your household electricity consumption.

Use power strips with on/off switches to make it easy to cut power to multiple devices at once. Or simply unplug appliances when they're not in use. Your wallet will thank you.

6. Use Fans Strategically

A ceiling or standing fan uses a fraction of the electricity that an air conditioner does. On milder evenings, a fan might be all you need. Even when you do use the aircon, pairing it with a fan allows you to set the aircon at a higher temperature while maintaining comfort, because the fan helps circulate the cool air more effectively throughout the room.

7. Monitor Your Usage

SP Group's app and website allow you to track your daily electricity consumption. Reviewing this data regularly helps you identify patterns and spot unusual spikes. Did your bill jump after you started working from home more? Is one particular week consistently higher? Data-driven awareness is the first step to meaningful reductions.

Some households have also invested in smart plugs that monitor the energy consumption of individual appliances. If you suspect a particular device is an energy hog, a smart plug can confirm it and help you decide whether it's time for an upgrade.

Every Bit Counts

None of these tips alone will slash your bill in half overnight. But combined, they can make a meaningful difference — potentially saving you $50 to $150 or more per month depending on your household size and current habits. In a climate where energy costs are likely to remain elevated, building these habits now is an investment in long-term savings. Your future self — and your bank account — will appreciate the effort.
