Singapore Electricity Tariff Tracker: Current Rate and 5-Year Trend

The current SP Group residential electricity tariff, for Q3 2026 (1 July to 30 September), is S$0.3191 per kWh before GST, or S$0.3478 per kWh including 9% GST. This is a 17% increase from Q2 2026 and the highest tariff on record. SP Group reviews and republishes this rate every quarter under EMA's regulatory framework.

What makes up the current tariff?

SP Group publishes the tariff as four separate components, each reviewed quarterly. Together they total S$0.3191 per kWh before GST for Q3 2026.

Energy Costs, which track the wholesale price of the natural gas Singapore imports to generate over 95% of its electricity, is by far the largest and most volatile component. Network Costs, the second-largest, funds grid infrastructure and is also the component EMA deducts when calculating the SCT solar export credit rate.

How has the tariff changed over the past 5 years?

The table below shows the tariff before GST, by quarter, sourced directly from SP Group's published rates via data.gov.sg's official dataset. GST itself has also changed over this period (7% through 2022, 8% in 2023, 9% from 2024 onward), so figures below are shown consistently before GST to avoid mixing different GST rates into one trend line.

The trend is not a straight line. Tariffs spiked through 2022 on the global energy crisis, eased gradually from 2023 through early 2026 as gas prices moderated, then jumped sharply again in Q3 2026. That volatility, not just the direction, is the core argument for solar: a system generates at zero marginal fuel cost regardless of which way the next quarterly revision goes.

Why does the tariff keep rising over the long run?

Singapore generates over 95% of its electricity from imported natural gas, so the energy cost component moves with global LNG prices, a market Singapore has no domestic production to buffer against. Rising carbon tax, S$25 per tonne from 2024, S$45 per tonne in 2026, scheduled to reach S$50 to S$80 per tonne by 2030, adds further structural upward pressure on top of fuel costs.

How does this affect solar payback?

A higher tariff directly shortens payback, since every kWh a solar system generates and you self-consume saves the current retail rate, currently S$0.3478/kWh including GST. Because homeowners on the regulated tariff have no ability to lock in a rate between quarterly reviews, a system installed today locks in effectively free generation regardless of where Q4 2026 or any future quarter's rate lands.

Does a rising tariff also mean a rising SCT export credit rate?

To some degree, yes, since SCT is calculated by deducting the Network Costs component from the regulated tariff, meaning it moves in the same direction as the tariff whenever the change comes from the Energy Costs component specifically, exactly what drove the Q3 2026 jump. A homeowner exporting surplus generation under SCT sees that credit rate track the tariff's fuel-cost-driven swings, not stay fixed while only the import side of the bill moves, which is worth knowing when comparing your own export credit against an older, lower figure from a previous quarter.

Is there any way for a residential customer to lock in a rate instead of riding the quarterly reset?

Yes, through Singapore's Open Electricity Market, where retailers offer fixed-price plans that hold a contracted rate for a set term, insulating a household from quarterly tariff volatility in either direction for the length of that contract. This is a genuinely different lever from solar, a financial hedge through a fixed-price contract rather than a physical hedge through your own generation, and the two are not mutually exclusive: a homeowner can pair a fixed-rate retailer plan with solar self-consumption, though the specific export scheme that applies shifts to ECIS rather than SCT once buying from a retailer rather than SP Group directly.

When is the next tariff revision?

SP Group publishes a new rate for each upcoming quarter shortly before it takes effect, typically in the final weeks of the preceding quarter. The Q3 2026 rate above applies through 30 September 2026; the Q4 2026 rate (1 October to 31 December) will be published by SP Group ahead of that date.
