Media Release Electricity Tariff Revision For The Period 1 January to 31 March 2019 Singapore, 30 December 2018 – For the period from 1 January to 31 March 2019, electricity tariffs (before 7% GST) will decrease by an average of 1.2% or 0.28 cent per kWh compared to the previous quarter. This is mainly due to the lower cost of natural gas for electricity generation compared to the previous quarter. For households, the electricity tariff (before 7% GST) will decrease from 24.13 to 23.85 cents per kWh for 1 Jan to 31 March 2019.
