It’s saving money.
Especially when it comes to utilities like electricity.
In fact, when we first wrote this article and did a comparison between the Open Electricity Market (OEM) electricity retailers, even the Straits Times picked it up.
We then figured that a comparison tool might be easier to find the best open electricity market plan for the Seedly Community and decided to build that.
Totally NOT out of selfish reasons, of course.
It’s not like we used it to find out how to lower our electricity bill and then thought that maybe everyone else can benefit too…
Editor’s note: (rolls eyes)
What Is the Open Electricity Market (OEM)?
In October 2017, the Electricity Market Authority (EMA) first announced the Open Electricity Market (OEM) initiative in a bid to liberalise and encourage innovation in the power industry.
Fast forward to May 2019, all households in Singapore can choose to switch from SP Group to their preferred electricity provider.
So… Who Are the Electricity Retailers in the OEM?
There are 12 electricity retailers in Singapore:
- Best Electricity Supply Pte Ltd
- Diamond Energy Merchants Pte Ltd
- Geneco (by Seraya Energy Pte Ltd)
- iSwitch Pte Ltd
- Keppel Electric Pte Ltd
- Ohm Energy Pte Ltd
- PacificLight Energy Pte Ltd
- Sembcorp Power Pte Ltd
- Senoko Energy Supply Pte Ltd
- Sunseap Energy Pte Ltd
- Tuas Power Supply Pte Ltd
- Union Power Pte Ltd
What Types of Electricity Price Plans Do They Offer?
Now you’re asking the right questions.
Most OEM retailers offer a selection of 3 different price plans.
Fixed Price Plan
This is similar to SP Group’s electricity plan.
You sign a contract with them and pay a fixed rate for whatever amount of power used.
For obvious reasons, all of the electricity retailers are offering fixed prices plans which are competitively priced (read: lower than SP).
Discount Off Regulated Tariff (DORT) Plan
The price you pay is pegged to the regulated tariff announced by EMA, albeit at a discount.
Because SP Group’s price plan is always determined by EMA’s regulated tariff.
This means that you’ll always be paying less than what SP Group would charge you if you’re on a DORT plan.
These include peak and off-peak packages where the electricity retailer charges higher prices during peak hours and lower prices during off-peak.
Ideal if you are usually awake during off-peak hours (read: are a night-owl).

If you’d like to know how much you can potentially save if you switched to an OEM retailer, let’s have a look at how much Singaporeans spend on electricity per month, on average.
Using the current Q2 2021 (1 April 2021 to 30 June 2021) electricity tariff rate: 24.13 cents per kWh (including GST).
|Property Type||Average Electricity Consumption Per Month (kWh)|
(as of March 2020)

How Much Do Singaporeans Spend on Electricity Every Month?
Singaporeans are subjected to Electricity Tariff, which is regulated by the Energy Market Authority (EMA).
For Q1 2020, the electricity tariff is 22.21 cents per kWh (excluding GST).
The Electricity Tariff is made up of 4 main components:
|Electricity Tariff Components||Price||How Often Is It Reviewed?|
|Market Administration and Power System Operation Fee|
(Paid to Energy Company and Power System Operator)
|Market Support Services Fee (MSS)||0.40 cents/kWh||Annually|

The sum of the 4 components makes up your Electricity Tariff, which will be what the consumer pays for their monthly electricity bill.
Some Commonly Asked Questions About The OEM
1. Why Are Electricity Retailers Able Charge Lower For Electricity Than SP Group?
You’re probably going, “WALAO, has SP Group been overcharging me ALL THESE YEARS?!”
The regulated tariff takes into account the cost of producing and delivering electricity which includes the cost of building and operating power plants as well as maintaining the power grid.
The rates offered by retailers, on the other hand, reflect current market conditions and the short-term costs of producing electricity.
If the current market conditions see excess in supply as compared to demand, the price of electricity will naturally be lower.
These retailers can then go into the wholesale market and buy electricity in bulk from power generation companies.
Of course, these prices offered by retailers are only fixed during your contract. So they can adjust their prices and discounts over time. But fret not, you can always switch back to buying electricity at the regulated tariff from SP Group at any time – after you complete your contract of course; unless you wish to pay the early termination fee…
2. When Can I Start Applying?
As of today, you can switch to an Open Electricity Market retailer anytime.
But as with anything that has to do with money, take the time to understand the OEM before you switch.
The retailers might be throwing promo codes around like Oprah Winfrey and shouting out how they’re the cheapest in town.
But you really should take the time to understand the other stuff which electricity retailers don’t usually talk about like:
- Administrative fee
- AMI meter installation fee
- Auto-renewal of contract clause
- Carbon tax
- Early termination charges
- Late payment fee
- Paper bill
- Security deposit
- Transmission loss factor
- U-Save GST Voucher
3. What Is Transmission Loss Factors (TLF)?
To put it simply, it’s a scaling factor that has been applied at the metering point to account for network and transformer loss.
Think of it this way: To get you one unit of electricity, the retailer needs to send two units of electricity to account for the possible loss of one unit of electricity when electricity travels across such a vast distance from the power plant to your home. That’s the TLF that they need to factor in when charging you.
Most of us fall under the 230kv/400kV load.
SP Group should have already adjusted this to reflect the actual consumer use, so retailers will adhere to SP Group’s recommended TLF and bill you accordingly.
