Is your home powered by one of the cheapest electricity price plans in Singapore at the moment? Find out if it’s time to make the switch.

Every spending situation is unique. SingSaver assembles the ‘Best For‘ list, so you can decide what’s best for you.

Households in Singapore no longer just have one default option — SP Services — when it comes to powering their home. Since the liberalisation of the Open Electricity Market (OEM), consumers are free to take their pick from 9 energy providers in the Open Electricity Market. 

While switching from SP Services to one of the other energy providers isn’t compulsory, it is always nice to have options, especially when those options help lower your electricity bills. 

Below, we share more about the different energy providers in Singapore, their unique features, and the one offering the cheapest electricity plans.

Want a taste of having your home powered by an Open Electricity Market retailer? Consider Geneco’s aptly named Give Us A Try 6-month trial electricity plan that comes with Price Match Guarantee

At 25.10¢ per kWh (including GST), the price you see is the price you pay. There are no monthly fees and no transmission loss charges. If you chance upon a lower price than what Geneco is offering for such a trial plan within seven working days of signing up, Geneco will refund you the difference for the contract period. T&Cs apply. 

Want something more sustainable? Simply add on Power Eco. Select Carbon Credits (CC) or Renewable Energy Certificates (REC) and determine the percentage level you’re comfortable with. The costs associated with Power Eco will be added on to your Base Price Plan thereafter. We like how easy it is to customise your very own green add-on according to your own terms! 

SP Services

SP Services is the default energy provider for households in Singapore. If you don’t make the switch to an Open Electricity Market retailer, your home will be powered by SP Services. 

SP Services sets the electricity tariff every quarter to reflect the actual cost of electricity. This tariff affects the price plans the Open Electricity Market energy providers offer regardless of whether they are fixed price plans, discount off regulated tariff price plans or peak/non-peak price plans. 

For those who are wondering, the current electricity tariff for 1 October 2021 to 31 December 2021 is set at 25.80¢ per kWh (including GST). Your electricity bill depends on how much electricity your household consumes. SP Services doesn’t have any special price plans for consumers to choose from.

Keppel Electric

Are you a night owl? Do you work through the night? Does your family blast the air-conditioner throughout the night? If your answer is yes, consider the 24-month peak/off-peak KNIGHT plan that Keppel Electric offers. 

At the time of writing, the off-peak fixed rate that applies from 11pm to 7am is 22.11¢ per kWh (including GST), while the peak fixed rate that applies from 7am to 11pm is 28.74¢ per kWh (including GST). 

The energy provider also offers an assortment of fixed rate plans. 

Be sure to use their Electricity Plan Calculator to calculate your potential savings and to find the electricity plan that best suits your budget and lifestyle!

Tuas Power

One of the best perks about getting Tuas Power to power your home is the free 12-month insurance protection thrown in when you sign up or renew your electricity plan with the energy provider. This is valid if your electricity plan has a contract duration of 12 months and above. 

Underwritten by Singlife, you can choose to be covered with (i) dengue aid insurance, (ii) home insurance, or (iii) utilities relief insurance. T&Cs apply. 

Tuas Power offers 12- and 24-month discount off regulated tariff and fixed price plans, as well as 18-month fixed price plan. Customers of Tuas Power will continue receiving their bills via SP Services.

Sembcorp Power

Keen on living greener without breaking the bank? Sembcorp Power’s electricity plans will be right up your alley. All their electricity plans are green, no matter which one you pick. The energy provider promises that 50kWh of Green Energy will be supplied per month to customers on fixed price plans, discount off regulated tariff plans and no-contract plans. 

For a 100% Green Energy Plan that’s powered by solar panels and validated through the retirement of local Renewable Energy Certificates (RECs), opt for the Sunshine Plan

That’s not all. Sembcorp Power also offers complimentary 12-month home protection insurance for new customers who sign up for their electricity plans, excluding those who go for Sembcorp Power’s no-contract plan. T&Cs apply.

Diamond Electric

Diamond Electric’s electricity plan doesn’t come with monthly service fees, security deposit or even early termination charges. You even get to enjoy complimentary personal accident insurance coverage of up to S$20,000 by AIA.  

If you’re looking to switch to another OEM electricity retailer further down the road, remember to give them at least 30 days of advance notice to avoid any unnecessary termination charges! 

For those seeking discounts and options, Diamond Electric isn’t the best for you. Its electricity price right now is the same as SP Services’ regulated tariff at 25.80¢ per kWh (including GST).

Note: The plan is temporarily not available to consumers.

Pacific Light

Apart from its very user-friendly, easy-to-navigate website, Pacific Light has an incredibly wide range of electricity plans available, including Sunny Side-Up (fixed green price plan), off peak/peak plan, no-contract plan, fixed price plans, discount off regulated tariff plans, tiered usage price plan and more. 

The most interesting electricity plans available at Pacific Light include: 


Sunseap offers a range of customisable green electricity plans that let you decide how environmentally-friendly you want your energy consumption to be. Its electricity plans do not come with transmission loss charges and security deposit. 

Here’s a quick breakdown of Sunseap’s electricity plans: 

  • Sunseap-One (1% solar energy): 6-month contract at 27.55¢ per kWh (including GST)
  • Sunseap-100 (100% solar energy): 12-month contract at 29.32¢ per kWh (including GST)

Senoko Energy

All of Senoko Energy’s electricity plans include at least 3% renewable solar energy. Regardless of whether you’re looking for a 12- or 24-month discount off regulated tariff or fixed price electricity plan, you’re bound to find something that suits your family’s needs. 

If you’re very environmentally conscious, definitely consider Senoko Energy’s 100% carbon neutral LifeGreen24 electricity plan.

In case you’re curious, Senoko Energy offers a S$30 referral bill rebate while most OEM retailers offer S$20 at the time of writing.

Union Power

Union Power offers a 6-month discount off regulated tariff and fixed price plan only, so take note if you’re looking for more choices from this OEM retailer. You don’t have to deal with security deposit, registration fee, or transmission loss factor costs when switching to Union Power though. 

It also offers Electricity Group Buy, which is exactly as it sounds— group buy for electricity consumption. To enjoy bulk discounts, you’ll need to first gather a minimum of 30 people.

Which energy provider should I choose?

Consider your preference, budget and household electricity consumption pattern before deciding which energy provider’s electricity plan you might want to go for. Spend some time reading about the things to watch out for when choosing an energy provider

Other things worth considering? Credit card rebates, referral rebates, promo codes and each retailer’s unique value proposition. 

As it stands, your electricity bills tend to be lower if you make the switch — Open Electricity Market retailers strive to offer competitive rates based on SP Services’ quarterly reviewed regulated electricity tariff. 

*Note: All prices mentioned are based on the current regulated tariff of 25.80¢ per kWh (including GST).
