The regulated tariff is the default electricity purchase option that most Singapore households are currently on. Set by SP Group and regulated by EMA, the tariff rate you pay is revised quarterly to reflect the costs of fuel and electricity production.
The tariff is set based on the average daily natural gas prices in the first 2.5 months in the preceding quarter. For instance, the average of daily natural gas prices from 1 January to 15 March is used to set the tariff for April to June.
This helps to smoothen out any large swings in gas prices, though this also means that changes in global gas prices can take some time to show up in your electricity bill.
With global gas prices being significantly higher in April-June 2026 compared to the preceding period, the electricity tariff for the third quarter of 2026 will see a significant increase.
For July to September 2026, the regulated tariff is 31.91 cents/kWh (before GST), or 34.78 cents/kWh (with GST). To give you a sense of what this means for households, the average monthly electricity bill for families living in HDB four-room flats will increase by $17.14 (before GST).
Much of the recent rise in global gas prices has been driven by the conflict in the Middle East, which has disrupted global energy markets and affected fuel prices worldwide. To find out more about how the Middle East conflict has affected energy prices in Singapore, click here.

There are two main components in the electricity tariff:
Fuel costs make up the largest portion of the tariff. Singapore generates most of its electricity from imported natural gas. The tariff is set based on the average daily natural gas prices in the first 2.5 months in the preceding quarter.
Non-fuel costs cover everything else involved in generating electricity and delivering it reliably.
When pricing electricity, we believe in reflecting its true cost to discourage wasteful consumption.
EMA commissions benchmarking studies which have shown that our regulated electricity tariff for residential consumers is comparable to that of similar cities around the world.

Since the liberalisation of the electricity retail market, households have greater flexibility and choices in how they buy electricity. Apart from buying electricity from SP Group at the regulated tariff, households can also choose from a range of price plans offered by various electricity retailers.
Consumers can opt for standard or non-standard price plans when buying electricity from a retailer. Standard price plans offer all-inclusive, fixed electricity rates over a contract duration of 6, 12, or 24 months, while non-standard price plans are more variable in their rates, fees, and contract duration.
