You can’t procrastinate forever — the Open Electricity Market (OEM) initiative has been in full swing for some time so if you haven’t already, it’s right about time to choose your preferred electricity retailer in Singapore.

If you’ve done zero research, consider reading our 101 guide on the OEMFAQ guide on making the switch from Singapore Powers (SP) and/or our list of hidden costs to look out for.

The Open Electricity Market (OEM) and electricity retailers in Singapore

The OEM is a turning point in Singapore history. Up until 1 Nov 2018, electricity was provided by SP (Singapore Power) and all we had to do was pay our bills.

But now, there are many electricity retailers with published prices offering 2 standard pricing models… that means more than 20 electricity packages to compare. Naturally, there’s some analysis paralysis…

To get you started, here are 3 steps to picking an electricity retailer:

Step 1: Decide if you want a (a) fixed rate plan or (b) discount off the regulated tariff. Some retailers have non-standard plans as well.

Step 2: Decide how long you want your contract to be — it can be as short as 6 months to as long as 3 years.

Step 3: Finally, compare the prices and choose your preferred power soulmate.

Before your eyes start twitching and your brain starts short-circuiting, we’re here to play cupid with a comprehensive comparison of all the current retailers.

There’s an official OEM comparison tool which lets you easily estimate your electricity bills and compare providers. You just need to input your type of residence, average consumption, and preference for pricing models (fixed or discount off regulated tariff).

Using that calculator, let’s find out what are the cheapest retailers for a 4-room HDB flat with an assumed average consumption of 360 kWh / month.

Cheapest electricity retailers for fixed price plans

For these price plans, you pay a fixed price (calculated per kWh) for the duration of your contract. The rate is independent of the regulated tariff, and is applied to your total electricity consumption (regardless of what time you use it).

Currently, short-term contracts offer the cheapest prices — possibly to encourage you to give these electricity retailers a try. (The Geneco plan is literally called “Give Us A Try”.)

Electricity Retailer Fixed Price Plan Price (per kWh)
Geneco Give Us A Try (6 months) $0.2510
Sembcorp Power Fixed Price Plan (6 months) $0.2710
Sunseap Energy 6 Months Plan $0.2868
Union Power Union Saver 6 (6 months) $0.3210

If you don’t want the hassle of possibly having to switch out half a year later, a 12- or 24-month contract will get you the next cheapest rates.

Electricity Retailer 12 Months Fixed Price Plan Price (per kWh)
Geneco Get It Fixed (12 months) $0.2510
Keppel Electric Fixed12 (12 months) $0.2580
Pacific Light Savvy Saver (12 months) $0.2568
Sembcorp Power Fixed Price Plan (12 months) $0.2710
Senoko LifePower12 (12 months) $0.2520
Sunseap Energy
Tuas Power PowerFIX 12 (12 months) $0.2711
Union Power

 

Electricity Retailer 24 Months Fixed Price Plan Price (per kWh)
Geneco Get It Fixed (24 months) $0.2550
Keppel Electric Fixed24 (24 months) $0.2580
Pacific Light Savvy Saver (24 months) $0.2568
Sembcorp Power Fixed Price Plan (24 months) $0.2722
Senoko LifePower24 (24 months) $0.2568
Sunseap Energy
Tuas Power PowerFIX 24 (24 months) $0.2711
Union Power

Note that fixed electricity rates offered change much more often than the pegged ones (see below), and the frontrunners switch around every month or so.

Cheapest electricity retailers for “discount off regulated tariff” price plans

For this type of plan, you get a fixed discount off the regulated tariff set by the Energy Market Authority (EMA), which is currently $0.2722 per kWh (1 January to 31 March 2022).

You pay a floating rate, subject to the tariff’s quarterly fluctuations. In other words, your bill will always be X% cheaper than if you opted for SP.

Let’s do a price comparison based on a 4-room HDB flat with an assumed average consumption of 360 kWh / month.

If you’re with SP, your bill would have been… $97.992 per month.

Electricity Retailer Discount Off Tariff Plan Discount Bill
Geneco
Keppel Electric
Pacific Light Confirm Save 3% $95.05224
Sembcorp Power
Senoko LifeSave12 6% $92.11248
Sunseap Energy
Tuas Power PowerDO 12 3% $95.05224
Union Power
Diamond Electric Freedom – RES 0% $97.992

As you can see, “discount off tariff” electricity plans are not offered by most electricity retailers right now. The discounts that you get are pretty negligible, with Senoko’s 12-month LifeSave12 plan offering the highest 6% discount.

Other non-standard price plans – “peak & off-peak”, free gifts & more promotions

In addition to the standard plans, some retailers offer non-standard packages to cater to different profiles of users so be sure to check their official websites when picking a plan.

A popular one is the “peak and off-peak” pricing, which splits the day into 2 time slots — day and night — charging different rates for it. So if you can use most of your electricity during off-peak hours, you can enjoy cheaper prices.

Other non-standard plans include handing out cash rebates (usually calculated based on the average of a few months), free gifts (like iPads!), and discounted prices when bundled with other products.

The retailers were reasonably aggressive with their prices and promotions a few years back. However, those promo codes and freebies have since waned.

I don’t really care — and neither should you — because these promotions are seasonal and change from week to week, and year to year. The cheaper prices should be incentive enough for you to make the switch from SP.

What is Transmission Loss Factor?

When the Open Electricity Market first launched, it was really difficult to find out which electricity plan is really the cheapest because some of them were complicated by this troublesome thing called Transmission Loss Factor.

When power is delivered to your home, a certain percentage of it is “lost”, and different retailers dealt with this loss in different ways. Some factored the loss into their rates, while others left it as a surprise for their customers.

However, since November 2018, most retailers have standardised their billing calculation remain competitive. This means that, for those of us not gifted in Maths, we no longer have to do complicated calculations to figure out how much exactly electricity costs. Yay!

Still, these things are always subject to change, so be kiasu and please double-check your contract to make sure. If you’re not sure about how your preferred retailer calculates your consumption, please give them a call.

Just in case you’re curious, here are the published Transmission Loss Factors, which can be found on the OEM website.

Load Transmission Loss Factors (from 1 April 2021)
230kV / 400kV 1.0
66kV 1.0
22kV 1.004336
6.6kV 1.016689
230V 1.030905

Singapore’s power is delivered at 230V, i.e. the TLF is 1.030905 currently. There are two forms of electricity billing: Either according to the meter, or loss-adjusted billing.

In general, billing according to the metered reading is more straightforward and cheaper than loss adjusted readings. No hidden charge mah. You just pay the X price multiplied by your consumption. For example, $0.2722 X 360 kWh = $97.99. That’s it, no need to think.

For loss-adjusted billing, you need take the TLF and multiply it to your total consumption. So it would instead be: $0.2722 X 360 kWh X 1.030905 = $101.02. That’s about $3 more!

Best cashback credit cards for paying your electricity bills

Most electricity retailers make it easy for you to set up a recurring charge to your credit card of choice… but bear in mind that not all credit cards will give you cash rebates for your electricity bills.

For example, some credit card T&Cs put “recurring payments” and “bill payments” under their list of general exclusions. This can happen even if it’s supposedly a cashback card with no categories or restrictions.

To play it safe, we would recommend credit cards that explicitly mention electricity bills as one of their cashback categories. The following are good options:

If you want an all-purpose credit card, the UOB Absolute Cashback is the one to go for. You can use it to pay your electricity bills, and also insurance premiums!

Consolidate your bills on a UOB One card and hit the minimum spend of $500, $1,000 or $2,000 every month to get a flat quarterly rebate. It works out to ether 3.33% or 5% a month in rebates.
