S'pore household electricity contract prices go up as much as 11% amid Middle East conflict

Household electricity contract renewal prices have increased by as much as 11 per cent since the start of the U.S.-Israel war on Iran, according to CNA.

On Feb. 27, a day before the war began, fixed-price retail plans for residences ranged from 24.88 to 28.67 cents per kilowatt-hour (kWh), according to CNA's figures.

Depending on the plan and retailer, prices increased between 1.2 and 11.3 per cent.

The biggest increase belonged to Senoko Energy Supply and PacificLight Energy’s 24-month fixed price plans, which rose from 25.88 cents to 28.80 cents per kWh.

Checks by Mothership on Open Electricity Market's price comparison website on Mar. 20 showed that residential energy plan prices spanned from 28.90 to 29.18 cents per kWh.

Prices also dependent on rebates

According to CNA, a four-room public housing flat consumes an average of 357 kWh of electricity per month.

This translates to a S$10.42 price increase if the 24-month fixed price plan under Senoko Energy Supply and PacificLight Energy were renewed today.

These prices are inclusive of goods and services tax (GST).

However, each retailer has different promotional gifts and rebates that may affect costs.

Senoko Energy's plan includes a promotional gift and a rebate package valued at S$240, up from S$160 previously.

Geneco and Keppel Electric’s 24-month fixed price plan jumped by 4 per cent from 27.68 to 28.80 cents per kWh, a S$4 increase based on the four-room flat average.

CNA reported that Geneco's maximum rebate decreased from S$195 before to S$165 after the war.

Plans withdrawn

Other retailers chose to withdraw specific plans and discounts from the regulated tariffs, the quarterly-reviewed government-regulated electricity rate.

Tuas Power Supply's six-month fixed-price plans and 10 per cent off regulated tariff plan were no longer available on Mar. 20, reported CNA.

According to October 2025 data from the Open Electricity Market, 26.57 per cent of residential accounts were on retail price plans.

By residential market share, the largest retailers are as follows: Geneco (29.6 per cent), Tuas Power Supply (23.9 per cent), Keppel Electric (21.5 per cent), Senoko Energy (16.3 per cent) and Sembcorp Power (5.3 per cent).

Other retailers take up around 3.5 per cent of the residential market share.
