SP Group announced on September 30, 2026 that Singapore’s regulated household electricity tariff will fall 10.4% to 28.59 cents per kWh before GST for October 1 to December 31, reflecting lower natural gas prices in the preceding quarter. The revision follows a record-high third-quarter tariff driven by Middle East conflict-related fuel costs, and SP Group has said tariffs could rise again if recent fuel price increases persist.

Singapore’s household electricity tariff will fall 10.4%, or 3.32 Singapore cents per kWh, from October 1 to December 31, SP Group said on Wednesday. The rate drops to 28.59 cents per kWh before goods and services tax, from 31.91 cents in the previous quarter, and stands at 31.16 cents per kWh with the 9% GST included. The overall electricity tariff before GST, which covers both household and non-household consumers, will fall by an average of 10.6%, or 3.32 cents per kWh, compared with the previous quarter.
The average monthly bill for households in four-room Housing and Development Board flats is reported to fall by about S$13 before GST, with published figures varying slightly across reports.
How The Tariff Is Set
SP Group and City Energy review their electricity and gas tariffs every quarter under guidelines set by the Energy Market Authority. Regulated rates are based on gas prices during the first two and a half months of the preceding quarter, so the October to December tariff reflects lower gas prices between July 1 and September 15.
The fourth-quarter reduction follows an increase in the prior period. Electricity tariffs rose 17% between July and September, and town gas rates rose 7.1%, as natural gas prices climbed during the Middle East conflict. In its June 30 tariff revision, SP Group had said fourth-quarter tariffs could decrease if the Middle East situation improved and global fuel prices fell.
Town Gas And Outlook
City Energy said in a separate statement on Wednesday that the household town gas tariff before GST will fall by 2.03 cents per kWh for October to December.
Both utilities said the reduction may not last. SP Group said changes in fuel prices take time to be reflected in tariffs, and that global fuel prices have risen since September 2026 due to escalating tensions in the Middle East. It said electricity tariffs could rise in the next quarter if higher fuel prices persist. City Energy said town gas tariffs are also expected to rise next quarter if the trend continues.
