How much Singaporeans spend on electricity bill every month?

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 Q4 2018, which is from 1 October 2018 to 31 December 2018, the Electricity Tariff is at 24.13 cents/kWh (25.82 cents/kWh with GST)

Electricity tariff Q4 2018The 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.
  • Market Support Services Fee (MSS) – 0.40 cents/kWh
    Reviewed annually.
  • Network Cost – 5.31 cents/kWh
    Reviewed annually.
  • Energy Cost – 18.37 cents/kWh
    Reviewed quarterly.

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

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.
