The overall electricity tariff (before GST), including tariffs for non-households, will decrease by an average of 10.6% or 3.32 cents per kWh compared with the previous quarter.

SP Group reviews the electricity tariffs every quarter based on guidelines set by the Energy Market Authority (EMA). The energy cost component of the electricity tariffs for each quarter is set using the average natural gas prices in the first two and a half months of the preceding quarter. Accordingly, the energy cost component of the electricity tariffs from 1 October 2026 to 31 December 2026 reflects the natural gas prices which were lower from 1 July 2026 to 15 September 2026, in tandem with lower global fuel prices.

Changes in fuel prices take some time to be reflected in the electricity tariffs. Global fuel prices have risen since September 2026 due to escalating tensions in the Middle East. Should this persist, electricity tariffs are expected to increase for the subsequent quarter.
