Media Release Electricity Tariff Revision for the Period 1 April to 30 June 2024 Singapore, 28 March 2024 – For the period from 1 April to 30 June 2024, the electricity tariff (before GST) for households will decrease by 0.3% or 0.10 cent per kWh compared with the previous quarter due to lower energy costs. The average monthly electricity bill for families living in HDB four-room flats will decrease by $0.33 (before GST). *before GST Electricity tariffs (before GST), including tariffs for non-households, will decrease by an average of 0.4% or 0.12 cent per kWh compared with the previous quarter. SP Group reviews the electricity tariffs every quarter based on guidelines set by the electricity industry regulator, Energy Market Authority (EMA). Please refer to Appendix 1 for the components of the electricity tariff, Appendix 2 for the tariffs approved by EMA, and Appendix 3 for the average monthly electricity bills for households. Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF The electricity tariff consists of the following four components: 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. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. 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. 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.   Q2 2024 TARIFF FOR HOUSEHOLDS (before 9% GST) Appendix 2 ELECTRICITY TARIFFS FROM 1 APRIL 2024 Appendix 3 AVERAGE MONTHLY ELECTRICITY BILLS FOR HOUSEHOLDS TARIFF WEF 1 APRIL 2024 (before GST)

18 February 2014 Using data to help consumers reduce their electricity consumption 1. A new pilot by SP Services (SPS) and the Energy Market Authority (EMA) will enable participating consumers to compare their electricity consumption against the average consumption of their neighbours; and through such comparisons, reduce their electricity usage over time. 2. The pilot will involve users of SPS’ My Utilities Portal (at www.spservices.com.sg), currently numbering at 260,000. These are consumers with e-billing accounts; the number may increase when more consumers sign up for e-bill service with SPS. They could compare their electricity consumption in the last 6 months against the national average consumption and the average consumption of their neighbours living in similar housing types (see Annex A for more details). 3. ‘’With this new comparison feature, we hope to raise customers’ awareness of their consumption pattern and hence encourage better energy-saving habits. This builds on our continuous efforts to equip the public with information on efficient use of energy,’’ said Jeanne Cheng, Managing Director of SP Services. 4. Chee Hong Tat, Chief Executive, EMA said, "Improving energy efficiency and helping consumers to save electricity are important priorities for EMA. These efforts will reduce costs for consumers, enhance Singapore’s energy security and benefit the environment. After gathering feedback from this pilot, we will work with SP Services on redesigning the hardcopy utilities bill to reach out to all 1.2 million households. We also plan to include comparisons of gas and water consumption data in the next phase.” 5. In the coming months, SP Services will be enhancing the pilot with additional features, and making this service available through other channels such as mobile applications. – End – 1 Jointly Issued by: SP Services Limited and Energy Market Authority About Singapore Power and SP Services Singapore Power Group (SP) is a leading energy utility group in the Asia Pacific.

End Yes End Note: Residential consumers refer to residential consumers not under master-sub arrangement December 2022 2 Solar PV – User Guide for Residential Consumers 2. Electricity Generation Licence The electricity licensing requirements for solar PV systems will be based on the aggregate of the Alternating Current (AC) inverter capacities (“installed generation capacity”) at the point of connection 1 to the grid. Any person who engages in the generation of electricity with a solar PV system with installed generation capacity of 1 MWac or more but less than 10 MWac is required to apply to EMA for a Wholesaler (Generation) Licence. For installed generation capacity of 10 MWac or more, he has to apply for a Generation Licence. All relevant licences should be obtained before any turn-on of solar PV installations. A summary of the licensing requirements is shown in the table below. Table 1: Licensing Requirements for Solar PV Systems Installed Capacity of Solar PV System Connected to the Power Grid? Type of Licence* Below 1 MWac 1 MWac or more but less than 10 MWac Yes No Yes No Yes 10 MWac or more No * An Electrical Installation Licence may still be required. Exempted Wholesaler (Generation) Licence Exempted Generation Licence Application for the wholesaler or generation licence can be made on EMA’s website: http://www.ema.gov.sg/Licensees_Electricity_Licences.aspx 3. Electrical Installation An electrical installation refers to any electrical wiring, fitting or apparatus used for the conveyance and control of electricity in any premises. A solar PV system installed within such premises forms part of the consumer’s electrical installation and should comply with the requirements stipulated in the Electricity Act (Cap. 89A), the Electricity (Electrical Installations) Regulations and the Singapore Standard CP5 Code of Practice for Electrical Installations. 1 The point of connection refers to the point at which the solar PV system is connected directly or indirectly to SP PowerAsset’s substation. December 2022 3 Solar PV – User Guide for Residential Consumers All electrical work for an electrical installation, including a solar PV system, must be undertaken or carried out by a Licensed Electrical Workers (LEWs). Such electrical work includes new wiring, rewiring and extensions which have to be tested before the supply is turned on. When consumer needs any electrical work to be done at his premises, he is advised to check that the person whom he intends to engage to undertake or perform the electrical work has a valid electrical worker licence issued by the Authority. It is an offence for a person: i. To carry out or caused to be carried out any electrical work unless he holds a valid electrical worker licence; or ii. To engage knowingly any person who is not a licensed electrical worker to carry out any electrical work. For more details, you may wish to refer to ELISE website for the list of LEW. Electrical Installation Licence All electrical installations used exclusively for domestic purposes except multi-metered premises are exempted from this requirement. Safety requirements Solar PV system requires regular inspection and maintenance to ensure that the system remains efficient and safe for operation. In most cases, equipment manufacturers will provide maintenance guidelines for their specific components. It is important to ensure that the maintenance requirement is carried out according to the recommendation and certified by a LEW. December 2022 4 Solar PV – User Guide for Residential Consumers 4. Connection Requirements If you intend to connect and operate your solar PV system in parallel to the power grid, your appointed LEW will have to complete the online Application Form and submit the following documents to SPS via Singapore Power (SP) eBusiness Portal: • Document Checklist and Declaration of Compliance to SP Powergrid’s (SPPG) Technical Requirements • Application for Net Export Rebate Form • Letter of Consent • PQ Compliance Report • Inverter(s) Specifications • Solar panel(s) Specifications • Inverter(s) Type Test Reports (Harmonics, Flicker, DC Injection) • Single Line Diagram (from PV system to Point of Common Coupling (PCC) • PSO Data Form (only applicable for solar PV system 1 MWac and above) Thereafter, your appointed LEW will have to consult SPPG on the connection scheme and technical requirements. The simplified connection and turn-on application process for solar PV systems are illustrated in Figure 2 and 3.

Market Settlement An overview of the available payment schemes can be found on EMA’s website. Non-contestable consumers (NCCs) Currently for residential NCCs with solar PV system, the solar energy produced is first offset by their consumption of that premise. Should there be excess solar energy to be exported back to the grid, they will receive payment (the prevailing low-tension electricity tariff minus grid charge) from SP Services (SPS) by way of credit adjustment to the monthly electricity bill. The quarterly revised low-tension electricity tariff can be found at the SP Group website (www.spgroup.com.sg). Contestable consumers (CCs) With the introduction of the Open Electricity Market “OEM”, residential CCs with solar PV system less than 10 MWac, is eligible to sell his excess output through SPS under the Enhanced Central Intermediary Scheme (ECIS). SPS will act as a central intermediary, by passing through the payment and relevant market charges to consumers. Excess solar electricity sold back to the grid will be paid the weighted average nodal price. December 2022 7 Solar PV – User Guide for Residential Consumers Such consumers can either choose (a) to install a meter to accurately measure the solar electricity generated, or (b) to estimate their solar generation. For option (a), consumers will need to install the relevant metering arrangement at each generation point. More details on the meters can be found in Section 7, AMI Meter Charges. For option (b), the solar generation will be estimated based on the Solar Generation Profile (SGP) 2 for the calculations of the relevant payment and market charges. Consumers need not install any meters. 6. Monitoring Requirements With the expected increase in solar PV systems in Singapore, the Power System Operator (PSO) would need to manage the intermittent nature of such sources to ensure that the security and reliability of the power system is not compromised. Most importantly, PSO also needs to ensure that sufficient reserve capacity is available to respond to sudden fluctuations in solar output. Hence, PSO shall require solar PV systems with an installed capacity of 1 MWac and above at each site/facility to provide the Active Power output (AC-side) of its solar PV system(s), sampled at one-minute intervals and solar irradiance from sensor installed in close proximity to the PV panels. For more detailed technical requirement, please contact EMA at EMA_PSO_EMA@ema.gov.sg. 7. AMI Meter Charges This section is only applicable to residential consumers who register their embedded solar PV systems under the ECIS and chose to install an AMI meter. The owner of the generation facility (i.e. solar PV system) is the Meter Equipment Service Provider (MESP) for the meter installation associated with it. However, consumers with embedded generation facility (with installed capacity of less than 10 MWac) may choose to engage SPPG to provide, install and maintain the generation meter. The fees applicable for providing such services by SPPG are shown in the table below: 2 The SGP is approved by the Energy Market Authority (“EMA”) and is based on factors such as Singapore's historical average solar irradiance from 7am to 7pm. This is standardised for all consumers with embedded solar PV systems and will be updated by EMA as new information becomes available.
