30 Mar 2016 For Immediate Release MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 APRIL TO 30 JUNE 2016 1. For the period from 1 Apr to 30 Jun 2016, electricity tariffs will decrease by an average of 9.6% or 1.83 cents per kWh compared to the previous quarter. The tariff reduction is due to the lower cost of natural gas for electricity generation which fell by 20.2% compared to 1Q 2016. While network costs went up due to infrastructure investment to replace ageing assets and meet rising electricity demand, the lower cost of natural gas more than offset this increase. 2. For households, the electricity tariff will decrease from 19.50 to 17.68 cents per kWh for 1 Apr to 30 Jun 2016. The average monthly electricity bill for families living in four-room HDB flats will decrease by $6.71 (see Appendix 3 for the average monthly electricity bill for different household types). 3. SP Services reviews the electricity tariffs quarterly based on guidelines set by the Energy Market Authority (EMA), the electricity industry regulator. The tariffs given in Appendix 1 have been approved by the EMA. _______________________________________________________________________________________________________ Issued by: SP Services Limited 10 Pasir Panjang Road #03-01 Mapletree Business City Singapore 117438 Co.

MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 JANUARY TO 31 MARCH 2022 Singapore, 30 December 2021 – For the period from 1 January to 31 March 2022, electricity tariff (before 7% GST) will increase by an average of 5.6% or 1.33 cents per kWh compared with the previous quarter. The increase this quarter is due to higher fuel costs. Around 95% of Singapore’s electricity is generated using imported natural gas at prices indexed to oil prices. Over the past few months, a confluence of recovering economic activity, severe weather events, and a series of gas production outages have sent global energy market prices significantly higher. These factors have raised electricity prices in many markets. For details on the components of the electricity tariff, please refer to Appendix 1: Breakdown of Electricity Tariff. For households, the electricity tariff (before 7% GST) will increase from 24.11 to 25.44 cents per kWh for 1 January to 31 March 2022. The average monthly electricity bill for families living in HDB fourroom flats will increase by $4.70 (before 7% GST) (Appendix 3: Average monthly electricity bills of domestic consumers). *before 7% GST SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). The tariffs shown in Appendix 2 have been approved by EMA. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: a) Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. b) Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. c) Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management, retail market systems as well as market development initiatives. d) Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.

MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 APRIL TO 30 JUNE 2022 Singapore, 31 March 2022 – For the period from 1 April to 30 June 2022, electricity tariff (before 7% GST) will increase by an average of 9.9% or 2.49 cents per kWh compared with the previous quarter. The increase is mainly due to higher energy cost arising from significantly higher global gas and oil prices exacerbated by the conflict in Ukraine. For details on the components of the electricity tariff, please refer to Appendix 1: Breakdown of Electricity Tariff. For households, the electricity tariff (before 7% GST) will increase from 25.44 to 27.94 cents per kWh for 1 April to 30 June 2022. The average monthly electricity bill for families living in HDB four-room flats will increase by $8.73 (before 7% GST) (Appendix 3: Average monthly electricity bills of domestic consumers). *before 7% GST SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). The tariffs shown in Appendix 2 have been approved by EMA. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: a) Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. b) Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. c) Market Support Services Fee (paid to SP Group): This is to recover the costs of billing and meter reading, data management, retail market systems as well as market development initiatives. d) Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.
