Singapore’s national grid operator, SP Group, said household electricity rates would climb by 2.1%, pushing tariffs to 29.72 cents per kilowatt-hour (kWh) and raising average monthly bills for four-room HDB flats by $1.96.

Separately, City Energy said the gas tariff would increase from April to June to 23.89 cents per kWh from 23.63 cents per kWh, reported The Straits Times.

Singapore energy regulator, the Energy Market Authority (EMA), said the latest tariffs were only partly affected by the rise in fuel prices caused by the strain in global fuel supply due to the ongoing Middle East conflict.

EMA said the full impact of fuel price hikes due to the Middle East conflict would only be felt later in the year, as tariffs for each quarter were determined based on the average fuel costs in the first two-and-a-half months of the preceding quarter.

EMA explained that the electricity and gas tariffs for the April to June period were based on fuel prices from January to mid-March.

“Because prices of natural gas had started to climb only after Feb 28, the regulated tariffs for electricity and gas in the second quarter of 2026 have only been partially affected by the rise in fuel prices,” it said.

It advised consumers and businesses to brace for higher and more volatile energy costs amid uncertainty over how long the Middle East war would last.
