Who Has the Cheapest Electricity Rates in Singapore? Who Has the Cheapest Electricity per kWh?

Well… if there’s one thing that Singaporeans care deeply about.

It’s saving money.

Especially when it comes to utilities like electricity.

In fact, when we first wrote this article and made a price comparison between the OEM electricity retailers, even The Straits Times picked it up.


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 the Singapore Power (SP) Group to their preferred electricity provider.

How Many Electricity Retailers Are There in Singapore?

There are currently eight surviving electricity retailers in Singapore:

  1. Geneco (by Seraya Energy Pte Ltd)
  2. Keppel Electric Pte Ltd
  3. PacificLight Energy Pte Ltd
  4. Sembcorp Power Pte Ltd
  5. Senoko Energy Supply Pte Ltd
  6. Sunseap Energy Pte Ltd 
  7. Tuas Power Supply Pte Ltd
  8. 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 two 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 is used.

For obvious reasons, all electricity retailers are offering fixed price plans that 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.

SP Group’s price plan is always determined by EMA’s regulated tariff, and DORT plans charge you by taking a percentage of the cost from the EMA stipulated electricity tariff for the quarter.

This means that you’ll always be paying less than what SP Group would charge you if you’re on a DORT plan.

However, there are no DORT plans offered in Q1 2023.

Who Has the Cheapest Electricity Rates in Singapore?

With so many retailers, choosing one can be quite a chore.

But we’re here to help by comparing all the plans they have for households.

If this is your first time choosing an electricity retailer, kWh stands for kilowatt per hour, i.e., the amount of energy used per hour. 

In general, we noted that Fixed Price Plans are cheaper than what you would pay if you’re paying SP based on the current electricity tariff.

SP Wholesale Electricity Plan: How Much Does 1 kWh Cost in Singapore?

On top of the regulated tariff, the SP Group offers a non-standard price plan where customers can buy electricity directly from the wholesale electricity market.

The good thing about this price plan is that there is no lock-in period or contract.

This means that you can switch back to the SP-regulated tariff plan or sign up for an OEM plan without any penalty.

However, note that the wholesale electricity price (WEP) varies every half hour depending on the prevailing demand and supply situation in Singapore’s wholesale electricity market.

Thus you will have to bear the risk of price fluctuations if there are any abrupt changes in electricity demand and supply.

You can refer to the chart below to get an idea of the fluctuation of WEP:

Just in the months of October and November 2021, the half-hourly prices ranged between $0.069/kWh and $4.42/kWh!

How Are Electricity Tariffs Calculated?

Singaporeans are subjected to Electricity Tariff, which is regulated by EMA.

For Q2 2023, the electricity tariff is 27.43 cents per kWh (excluding GST).

With GST, the electricity tariff is 29.62 cents per kWh.

For context, the Electricity Tariff is made up of four main components:

Electricity Tariff ComponentsPriceHow Often Is It Reviewed?
Market Administration and Power System Operation Fee

(Paid to Energy Company and Power System Operator)
0.06 cents/kWhAnnually
Market Support Services Fee (MSS)0.43 cents/kWhAnnually
Network Cost6.25 cents/kWhAnnually
Energy Costs20.69 cents/kWhQuarterly

The sum of the four components makes up your Electricity Tariff, which will be what the consumer pays for their monthly electricity bill.

Some Commonly Asked Questions About OEM Electricity Providers in Singapore

1. Cost of Electricity in Singapore: Here’s Why Electricity Retailers Able Charge Lower For Electricity Than SP Group?

You’re probably going, “WALAO, has SP Group been overcharging me ALL THESE YEARS?!”

Not exactly.

The regulated tariff considers the cost of producing and delivering electricity, which includes the cost of building and operating power plants and 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 supply 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 and early account closure fees

Speaking of early termination fees, please keep a lookout for them before you put pen to paper and sign the contract. 

For example, OEMs like Tuas Power charge a $200 (including GST) early termination fee for their plans.

Apart from early termination fees, be sure to take note of the hidden fees or terms & conditions when choosing your electricity retailer!

2. How Do I Switch to Electricity Retailer?

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 Are 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.
