How The Regulated Tariff Affects Your Electric Bill?

And Why Switching To iSwitch Helps You Save!

You Have Yet To Switch To An Electricity Retailer

That means you’re buying your electricity straight from SP Services. The regulated tariff is the price of electricity you will be paying on your usage.

You Have Switched To A Retailer & Picked A Fixed Price Plan

You will be paying the fixed price set by the retailer for the duration of your contract. That means no matter how high or low the regulated tariff becomes, you will be paying a fixed rate until your contract ends.

You Have Switched To A Retailer & Choose The Discount-Off-Tariff Plan

You will be enjoying a fixed discount rate off the regulated tariff. That means no matter how the tariff rises or falls, you will be enjoying guaranteed savings.

Understanding The SP Regulated Tariff

4 Components You Should Know
The SP tariff is made up of four key components that determine the cost of electricity in Singapore as well as what you are paying on your monthly electric bill.


1. Energy Fuel Cost

This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations.

2. Grid Network Charge

This fee is reviewed annually. This is to recover the cost of transporting electricity through the power grid.

3. Market Support Services Fee

This fee is reviewed annually. This is to recover the costs of billing and meter reading, data management, retail market systems as well as for market development initiatives.

4. Market Administration & PSO Fee

This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system. Paid to the Energy Market Company and Power System Operator.

Q6. Are there any additional electricity charges I should be aware of?

Yes, there are 7 additional charges you should take note of.

1. Transmission Loss Factor (TLF) Charge

In Singapore, electric power is delivered at 230V to consumers and during the transportation of electricity through the power grid to our homes and offices, a small percentage of the energy is lost. This percentage loss is known as the Transmission Loss Factor (TLF). The TLF effective 01 April 2020 for a load of 230V is 1.025599. You can view the latest TLF on the Open Electricity Market’s website.

Some electricity retailers, such as iSwitch, absorb the TLF charge for their customers. Hence, depending on the electricity retailer, consumers are billed either on metered readings or loss adjusted readings. If the retailer bills based on metered readings, consumers will just pay for the power usage that is recorded by their meter and the TLF will be borne by the retailer. However, if the retailer bills based on loss adjusted readings, the TLF will be factored in and the electricity bill will be calculated as such:

Electricity Usage = Metered Reading x TLF x Electricity Rate

2. Carbon Tax Charge
Singapore signed the Paris Agreement on climate change and as such, since January 2019, every electricity consumer in Singapore is subject to a carbon tax for their energy use. As power generation companies are liable for a $5 tax for every tonne of emissions and since they primarily burn natural gas for power generation, this tax is passed down to everyday consumers. As a reference, the carbon tax charge takes effect for every unit of electricity (in kWh) consumed from 1st January 2019 onwards.

Carbon Tax Charge = Electricity Consumed* x GEF-OM** x Carbon Tax Rate

Some electricity retailers, such as iSwitch, absorb the carbon tax for their residential customers.

**Learn more about carbon tax.

3. Early Termination Fee

Retailers may enact a penalty if you break the contract – mostly in the form of an early termination fee. For example, at iSwitch, a cancellation within 3 days from the date of application will incur a $100 cancellation fee. If the contract is cancelled after the initial 3 days, an early termination charge will apply, and this varies depending on the number of months left in the contract.

4. Security Deposit

Before the OEM, all consumers paid SP Group a security deposit in order to power up their homes back then. The same applies to electricity retailers too. The security deposit is refundable when an account is terminated and is primarily imposed to ensure any outstanding amount on a final bill will be settled. Any remaining amount will be refunded upon settling the final bill. Learn more about the security deposit here.

5. Advanced Meter Installation Fee

A meter reading is essential for the estimation of electricity usage and there are two types of meters available. The first type is the cumulative meter, which is what the majority of households in Singapore use. Meter readings are read manually by inspectors that head down to the premises once every two months.

The second type is the advanced meter that measures electricity consumption every 30 minutes, allowing consumers to be regularly updated with their electricity consumption. The advanced meter will require an installation fee of $40 (excluding GST).

6. Relocation Fee

Whether you are looking to move abroad or relocating to another premise, there might be a relocation charge depending on the electricity retailer. With iSwitch, when relocating within Singapore, if you provide valid documents and re-apply with iSwitch, there will be a small flat fee charged but don’t worry, the fee will be refunded to you once your new house contract is active. For more information click here.

7. Paper Billing Fee

Even though billing is now mostly performed online through digital statements that can be accessed from a retailer’s online portal or sent via email, consumers can still opt for paper bills. However, depending on the electricity retailer, there may be a nominal fee charged. With iSwitch, if you wish to have a hard copy of the bill you can manage all your bills from the iSwitch Self Service Portal or you can opt for paper billing at a flat fee of $1.07 (inc. GST)/bill.
