Singapore Electricity Tariffs Rise 17% From July 2026

Key Takeaways:
SP Group's regulated electricity tariff rises 17% from July to September 2026, driven by higher natural gas costs tied to the Middle East conflict. A typical 4-room HDB flat will pay about S$17 more a month, and landed homes which consume considerably more will see a larger increase still. Every kWh your solar system generates is now worth more too.

If you're on SP Group's regulated tariff, your next electricity bill is about to look different. From July to September 2026, household electricity tariffs are rising 17% before GST, the steepest quarterly jump in recent memory.

The Headline Numbers: Q3 2026 At a Glance

The new electricity tariff is 31.91 cents per kWh before GST, up 4.64 cents from the previous quarter. With 9% GST added, that works out to 34.78 cents per kWh. EMA's reference case is a 4-room HDB flat, where the monthly bill rises by S$17.14 before GST. Landed homes, which typically consume several times more electricity than a 4-room flat due to larger floor area, pools, and higher cooling load, will see a correspondingly larger increase in dollar terms.

Town gas tariffs are rising too, from 21.92 to 23.48 cents per kWh, a 7.1% increase so households on gas appliances will feel this on two fronts, not one.

What Drove the New Rates?

Singapore generates most of its electricity from imported natural gas, and gas prices are tied to global oil markets. The Energy Market Authority (EMA) sets each quarter's tariff based on fuel prices from the first two and a half months of the preceding quarter, so price shocks take time to reach your bill.

The lag explains why this quarter is sharper than the last. The Q2 2026 tariff only reflected the rise in fuel prices between February 28, when the Middle East conflict began, and March 15. The Q3 tariff captures a fuller stretch of the resulting fuel cost increase, which is why the jump is larger this time.

The tariff is made up of two main components. Fuel costs, the cost of imported natural gas, make up the largest portion and are the part that moves each quarter. Non-fuel costs cover network transport, billing and metering, market administration, and power station operations, these are reviewed annually rather than quarterly, and stayed stable this quarter. In other words, the entire 17% increase comes from one line item: fuel, which is exactly the cost solar lets you sidestep.

The Solar Advantage

A fixed plan protects you from rate volatility for at least 24 months. Solar protects you for 25 years, and it's the only option where rising tariffs in your favour rather than against you.

At previous tariff rates, a system offsetting 800 kWh a month saved you about S$218 before GST. With the new rates announced, the same system is estimated to save you about S$255.

Under GetSolar's Rent-to-Own plan, you only pay a fixed monthly fee over 5 or 10 years, with all maintenance, monitoring, and installation handled by us. With tariffs at 34.78 cents and climbing, your monthly savings will increasingly outpace that fixed payment.

Other Ways to Manage the Increase

1. July U-Save Rebates

Eligible Singaporean households in HDB flats will receive their next GST Voucher (GSTV) – U-Save rebates this July, worth up to S$190 depending on flat type, credited automatically to your SP Group account. It's a useful cushion for this quarter, though at S$17.14 more a month, the increase still adds up to over S$200 a year. The rebate softens this quarter's bill, but it doesn't offset the underlying rise.

2. The Open Electricity Market (OEM)

If you're still on the regulated tariff, this is a reasonable moment to compare options. Fixed-price plans lock in a rate for 12 or 24 months, protecting you from further quarterly swings, though you won't benefit if the tariff falls later. Discount Off Regulated Tariff (DOT) plans offer a guaranteed percentage off if you'd rather keep tracking the regulated rate. EMA's comparison website is the most reliable place to check current offers.

3. Smart Consumption Habits

Set air conditioning to 25°C or higher and use a fan to circulate air. Turn off appliances at the wall when not in use. Choose 5-tick appliances when replacing old ones.

Looking Ahead

A 17% jump in one quarter is the kind of number that should change how you think about your electricity bill, not just this quarter's, but every quarter after it. Fixed retail plans buy you certainty. Solar buys you certainty and turns the next tariff hike into bigger savings instead of a bigger bill.
