FAQ - Transmission Loss Factors (Business)
About Transmission Loss Factors
The Transmission Loss Factor (TLF) is calculated by the Market Support Services Licensee, SP Services Ltd in accordance with the methodology approved by the regulator, the Energy Market Authority of Singapore1.
In practice, it varies depending on the voltage level at which a consumer takes its electricity supply. The higher the voltage level, the lower the TLF. The metered quantity of electricity generated by generating units is more than the metered quantity of electricity consumed due to transmission losses (energy loss as heat as electric current passes through the transmission system (comprising the transmission network and distribution network)) as well as unaccounted for energy2.
The TLF is used to allocate the difference to consumers based on their deemed contribution to this difference (mainly transmission losses for Singapore, unaccounted for energy can be greater than transmission losses in a few other countries due to rampant electricity theft). The lower the voltage level of electricity consumption, the more transmission losses are incurred delivering electricity from where it is generated to where it is consumed. This explains why TLF is higher for electricity consumption at lower voltage levels.
The table below (Source: SP Group) shows the TLFs by the Market Support Services Licensee, SP Services Ltd, in accordance with the methodology approved by the Energy Market Authority of Singapore.

How Changes in TLF Impacts a Geneco Customer
For Geneco’s electricity customers, a change in the TLF which in practice applies from 1 April of every year may or may not impact their electricity bills. It depends on the contract terms which may be loss-adjusted or metered. Loss-adjusted means that the metered electricity quantity is multiplied by the relevant TLF to obtain the deemed electricity quantity consumed. Therefore loss-adjusted customers are affected by changes in the TLF.
For metered customers, the metered electricity quantity is not multiplied by the relevant TLF to obtain the deemed electricity quantity consumed. Therefore, metered customers are not affected by the changes in the TLF.
As metered customers do not have their metered electricity consumption scaled up by the TLF, they have an implicit discount vis-à-vis loss-adjusted customers paying the same electricity price. Pricing and discounts are therefore naturally different for loss-adjusted versus metered customers.
1 See Market Support Services Code here for more details.
2 A catch-all to classify the residual difference not accounted for by transmission losses. It includes under-metering of electricity consumption which can be due to various reasons and accounts for the fact that the estimation of transmission losses is not an exact science.
FAQ - Use of System Charge (Business)
Use of System Charge
The Use-of-System charges, which is payable to SP Group, is to recover the cost of transporting electricity through the national power grid. Note that the charges differ according to the voltage at which a consumer receives the electricity supply.

The Uncontracted Capacity Charge (UCC) applies in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity. UCC applies to:
- a. Normal customers without embedded generation;
- b. Customers with embedded generation who require top-up supplies and opt to summate their kW output from embedded generation and kW demand from the network (i.e Summation Scheme) for determining maximum demand; and
- c. Customers with embedded generation who require top-up supplies and opt to cap their power demand in kW drawn from the network (i.e Capped Capacity Scheme or Extended Capped Capacity Scheme). The UCC applies in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the contracted capacity and shall be limited to 20% of the Contracted Capacity.
- For Capped Capacity Scheme (CCS), the Uncontracted Standby Capacity Charge (USCC), at 5 times of Contracted Capacity Charge, applies in the event that the demand in kW (measured by the power meter) drawn from the network exceeds 120% of the contracted capacity for a duration of more than 10 seconds continuously.
-
For Extended Capped Capacity Scheme (ECCS), the 2-tier Uncontracted Standby Capacity Charge (USCC) applies as follows:
- Tier 1: 5 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 120% and up to 200% of the contracted capacity for a duration of more than 100 seconds continuously.
- Tier 2: 12 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 200% of the contracted capacity for a duration of more than 10 seconds continuously.
- For both CCS and ECCS, the consumer shall at its own expense, install and maintain Load Limiting Device, in accordance with requirements that the Transmission Licensee may stipulate from time to time.

Electricity Contracting Support for Large Business Consumers for month 2023 [CLOSED]
Update: Our Registration of Interest has closed. For other options, kindly visit EMA website. Thank you.
Introduction
- The Energy Market Authority (“EMA”) has received feedback that some large business consumers have experienced difficulties in securing fixed price electricity contracts in recent months due to unprecedented volatility in the global energy market as well as in the Singapore Wholesale Electricity Market.
- EMA has worked with Seraya Energy Pte Ltd to offer significant fixed price retail contracts to large business consumers who have difficulty in securing a retail contract for . While the fixed electricity price under the one-month retail contract reflects the prevailing high fuel prices, it will provide consumers with greater price certainty compared to the Wholesale Electricity Price (“WEP”).
- Large business consumers, with an Average Monthly Consumption of at least 4 MWh, are eligible to sign up for one-month fixed price retail contract for the month of .
- Towards the end of your contract, you can choose to re-contract with Seraya Energy Pte Ltd, switch to another retailer or switch back to buy electricity at the WEP.

Why is the electricity retail market being deregulated?
The deregulation of the electricity market will encourage and promote competition within the various players in the electricity market and hence, provide competitively priced packages to consumers.
Since 2001, EMA has progressively opened the retail electricity market to competition to allow business consumers more options to manage their energy cost. Instead of buying from SP Group at the regulated tariff, eligible consumers can choose to buy from a retailer at a price plan that best meet their needs, or buy from the wholesale electricity market at the half-hourly wholesale electricity prices. Those who exercise this choice are termed as contestable consumers.
How do I know if my business is eligible to switch from SP Services to Geneco?
With the open electricity market, all businesses are eligible to apply for contestability and switch to a retailer of their choice regardless of consumption. The application process is free of charge.
