How Much Do Singaporeans Spend On Electricity Bill Every Month?

Singaporeans are subjected to Electricity Tariff, which is regulated by the Energy Market Authority (EMA).

For Q3 2019, the electricity tariff is 24.22 cents per kWh, excluding GST.

Electricity Tariff for Q3 2019 Singapore

This Electricity Tariff is updated every quarterly, and as of Q3 2019, which last from 1 July 2019 to 30 September 2019, the Electricity Tariff is at 25.92 cents/kWh with GST.

The Electricity Tariff is made up of 4 main components:

ComponentsHow much it costs?How often is it being reviewed?
Market Administration and Power System Operation Fee

(Paid to Energy Company and Power System Operator)
0.06 cents/kWhReviewed annually
Market Support Services Fee (MSS)0.40 cents/kWhReviewed annually
Network Cost5.44 cents/kWhReviewed annually
Energy Costs18.32 cents/kWhReviewed Quarterly

The sum of the 4 components makes up your Electricity Tariff, which will be what the consumer pays for their monthly electricity bill.

Open Electricity Market In Singapore

The Open Electricity Market (OEM) has been rolled out to the whole of Singapore households and businesses. This reduces the reliant on SP group (SP Services) for electricity, where cost is based on a regulated tariff that changes every quarter.

These are the electricity retailers that are authorised at the moment:

The Ultimate Comparison: Cheapest Electricity Retailers In Singapore (Peak And Off-Peak Plans)

Assuming the peak period is defined as the time where most Singaporeans are at home. Hence, if you have working hours which are away from the norm, this might be the plan for you given that your electricity usage will be during off-peak.

We see less company is having the Peak and off-peak plans mainly due to the possible extra meter needed to be fixed at the household to monitor the electrical activity.

  • The meter installation fee costs $40 (before GST).

Why Can Electricity Retailers Charge Lower For Electricity Than SP Group?

Most Singaporeans are probably wondering why is it possible for cheaper electricity and yet, SP Group has been overcharging us for so many years.

To summarise this, it is because the introduction of retailers into the Open Electricity Market allows the retail arm of power generators or independent retailers which buy electricity in bulk from power generation companies into the market.

These retailers can now go into a wholesale market where prices change every 30 minutes depending on demand and supply, hence allowing a possible cheaper price should the retailer managed to purchase bulk electricity at a low price.

When Can I Start Applying?

Singaporeans can sign up for this service when the Open Electricity market is rolled out progressively in 4 geographical zones.

Transmission Loss Factors (TLF)

  • Scaling factors that are already applied at the metering point to account for network and transformer losses.
  • Residential customers fall under the 230.400V category when it comes to TLF
  • SP Group should have already adjusted this to derive the usage of consumers, hence, private retailers will simply take the information from SP Group and bill accordingly.
