On 1 July 2026, Singapore's regulated electricity tariff rose 17.0% — an increase of 4.64 cents per kWh in a single quarter. At 34.78 cents/kWh including GST (31.91 cents before GST) for 1 July to 30 September 2026, it is the highest household electricity tariff in Singapore's history. SP Group attributes the jump to the energy cost component, which reflects natural gas prices between 1 April and 15 June 2026, when global fuel prices were elevated. For an average HDB 4-room household, that alone adds about $17.14 a month before GST.
If you are still buying at the regulated tariff, this is the quarter where switching finally pays for itself several times over.
The thing nobody tells you: the rates are all identical
We pulled every residential plan listed on EMA's official Open Electricity Market price-comparison portal on 29 July 2026. There are exactly 16 residential plans in the entire market, and the result is unusually clean:
- Every 24-month fixed plan costs 27.50¢/kWh — Geneco, Senoko Energy, PacificLight, Keppel Electric, Tuas Power and Sembcorp Power. Not "about the same". Identical, to the cent.
- Every 12-month fixed plan costs 29.00¢/kWh — same six retailers.
- The only plans priced differently are the two green ones (Senoko LifeGreen24 at 27.88¢, PacificLight Sunny Side-Up 12 at 29.71¢).
- All 16 plans are fixed-price. There are currently no discount-off-tariff (DOT) plans listed for households.
So the usual "who is cheapest?" question has no answer this quarter, because nobody is. What actually differs is the sign-up rebate, and there the spread is real: from $255 down to zero.
What 27.50¢ actually saves you
Against the 34.78¢ tariff, a 24-month fixed plan is 7.28¢/kWh cheaper — about 21% off. Using the national average consumption for each home type (the same figures EMA's calculator uses):
| Home type | Avg. use/month | At SP tariff (34.78¢) | At 27.50¢ | You save |
|---|---|---|---|---|
| HDB 3-room | 266.6 kWh | $92.73 | $73.32 | $19.41/mth |
| HDB 4-room | 369.4 kWh | $128.48 | $101.59 | $26.89/mth |
| HDB 5-room | 435.2 kWh | $151.38 | $119.69 | $31.69/mth |
| HDB Executive | 528.0 kWh | $183.64 | $145.20 | $38.44/mth |
| Condo/Apartment | 544.4 kWh | $189.35 | $149.72 | $39.63/mth |
For a typical 4-room flat that is roughly $323 over a year — before any sign-up rebate. Add Geneco's $255 and the first year looks a lot better than doing nothing.
The catch worth understanding
A fixed-price plan locks your rate for the whole contract. That is protection if tariffs keep climbing, and a mild regret if they fall — the tariff is revised every quarter, and the Q3 spike was driven by a fuel-price window that may not repeat. Most retailers charge an early-termination fee if you leave before the contract ends, so a 24-month lock is a genuine commitment. If you would rather stay flexible, the 6-month options (Geneco's Give Us A Try, Tuas Power's PowerFix 6, both 29.00¢) cost 1.5¢ more per kWh for the freedom.
