Singapore Electricity Tariff October 2026: Current SP Rate, History Since 2022 and What It Means for Solar

What is the electricity tariff in Singapore right now?

Source: SP Group tariff revision for 1 October to 31 December 2026, announced 30 September 2026.

SP Group reviews the tariff every quarter under guidelines set by the Energy Market Authority. The energy cost part of each quarter's tariff is set from natural gas prices over the first two and a half months of the quarter before, so the October cut reflects the lower gas prices of July to mid-September. SP Group also flagged that global fuel prices have risen since September because of tensions in the Middle East, and that if this persists, tariffs are expected to increase for the following quarter.

Singapore electricity tariff history, 2022 to 2026

Regulated household (domestic, low-tension) tariff. Before-GST figures from SP Group, as compiled by the Department of Statistics in SingStat table M890991, and SP Group's quarterly releases for July and October 2026. Including-GST figures apply the GST rate in force each year (7% in 2022, 8% in 2023, 9% from 2024) and are rounded.

Three things stand out:

• July to September 2026 was the peak of this series, at 31.91 cents before GST, 17% above the quarter before it.
• The October cut does not take the tariff back to 2025 levels. At 28.59 cents before GST it is above every quarter of 2025 and the first half of 2026, though still below the 2024 quarters.
• GST has added to the bill as well as the tariff. It rose from 7% in 2022 to 9% from 2024, which is why the price you pay has moved more than the headline tariff.

What the current rate means for your solar savings

A home solar system saves you money in two ways, and both follow the tariff:

Power you use yourself. Every kWh your panels produce that the house uses straight away is a kWh you do not buy from the grid. From October that avoided cost is about S$0.31 per kWh. This is the bigger part of the saving for most landed homes.

Power you export. Surplus sent to the grid is credited under SCT at the regulated tariff less the grid charge, about S$0.22 per kWh this quarter. Because export is worth less than self-consumption, sizing a system to your daytime use matters, which we cover in how many panels your home needs.

These figures are illustrative. At July's rate the same system was worth a little more each year; at October's rate a little less. That is the point: a solar system's value tracks the tariff automatically, quarter by quarter, while the cost of the system is fixed on the day you buy it.

Should you wait for tariffs to fall further?

It is a fair question, and the honest answer is that no one can predict the quarterly tariff. SP Group itself has said the next move may be up. What is certain is that while you wait, you pay the grid price on every unit you use, whatever it is. A system starts offsetting that from the day it switches on, and over 25 to 30 years it will ride through many quarters of rises and falls. Owning the system outright means you keep all of that upside when the tariff goes up.

What happened in July 2026

For the July to September 2026 quarter the tariff rose to 34.78 cents per kWh including GST, about 17% above the previous quarter and the highest level in this series. We made a short video at the time on what that rise meant for landed homes, which still explains how the tariff feeds into solar savings.

If you already have solar, your October bill will show a smaller export credit per unit than in the summer, for exactly the same output. That is the tariff, not your system. Our guide to solar export credits on your SP bill explains how the credit is applied and how to withdraw it.

Frequently asked questions

What is the electricity tariff in Singapore from October 2026?
From 1 October to 31 December 2026, SP Group's regulated household tariff is 31.16 cents per kWh including GST, or 28.59 cents before GST. It is reviewed every quarter under guidelines set by the Energy Market Authority.

Did the electricity tariff go down in October 2026?
Yes. It fell 10.4%, or 3.32 cents per kWh before GST, compared with July to September 2026, because natural gas prices were lower over the reference period. It is still about 5% higher than April to June 2026 and above every quarter of 2025.

Will the electricity tariff rise again?
Possibly. SP Group said global fuel prices have risen since September 2026 because of tensions in the Middle East, and that if this persists, tariffs are expected to increase for the following quarter, from January 2027.

What was the highest electricity tariff in Singapore?
In the quarterly series since 2022, the highest was July to September 2026, at 31.91 cents per kWh before GST, or 34.78 cents including 9% GST.

Is solar still worth it at the lower tariff?
Yes. Each kWh your panels produce and you use saves about S$0.31, and surplus exported earns about S$0.22 under SCT. A typical 10 kWp landed-home system is worth roughly S$2,800 to S$4,200 a year at October's rates, and payback stays within the 3 to 6 year range.

How much is the solar export credit under SCT from October 2026?
About 22 cents per kWh. Under the Simplified Credit Treatment, exported solar is credited at the regulated tariff less the grid charge, and no GST is charged on the credit. It changes every quarter with the tariff.

Why is my solar credit smaller on my October bill?
Because the tariff fell, each exported unit is credited at about 22 cents instead of about 26 cents in July to September. Your system is producing the same; the rate per unit has changed.
