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

This Electricity Tariff is updated every quarterly, and as of Q2 2018, which is from 1 April 2018 to 30 June 2018, the Electricity Tariff is at 22.15 cents/kWh (23.70 cents/kWh with GST)

The Electricity Tariff is made up of 4 components:

  • Market Administration and Power System Operation Fee – 0.05 cents/kWh
    Paid to Energy Company and Power System Operator. Reviewed annually.

    Reviewed annually.

The Ultimate Comparison: Electricity Retailers in Singapore (Peak and off-peak plans)

Assuming 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 possible extra meter needed to be fixed at the household to monitor the electrical activity.

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.
