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.

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.

News Release SP Group building the first large-scale underground substation in Southeast Asia Singapore, 6 April 2021 – SP Group (SP) is constructing the first large-scale underground substation in Southeast Asia. Located at Labrador, SP will build its 230kV1 electrical substation underground to optimise space in land-scarce Singapore for urban growth and development. Group Chief Executive Officer of SP Group, Stanley Huang, said: “In our business of enabling a low carbon, smart energy future, we are building sustainable and resilient infrastructure. Taking a holistic approach, we are constructing this substation underground, freeing up space above for a 34-storey development. This is in line with Singapore’s urban renewal plans and our own SDG2 goals of ensuring access to reliable, sustainable and modern energy for all and tapping on innovation to build sustainable infrastructure.” Substations are part of essential infrastructure that power homes, offices, industries and public services. By freeing up prime land spaces for residential, commercial or recreational purposes, land use and resources can be optimised. By going underground, the Labrador substation alone will free up three hectares of prime land space, or the equivalent of four football fields. When in service, the substation will serve the electricity needs of nearby towns such as Alexandra, Clementi, Keppel, Pasir Panjang, and the Science Park district. Typically, building a substation underground would be more resource-intensive and require specialised engineering capabilities as compared to above-ground. This is due to complexities in construction and the need to use materials and equipment that are suitable for subterranean environment. For example, detailed engineering studies and suitable construction methods are implemented to control the impact to the surrounding buildings and infrastructure. In addition, the equipment in the substation must be of low-fire risk, with cooling systems installed to prevent the build-up of heat in the equipment. The long-term benefits of building substations underground outweigh the costs. In addition to optimising land resources for other purposes, underground substations have a lower risk of being exposed and damaged. This will enhance asset and network security. Mr. Huang added: “Leveraging our extensive experience in constructing the underground electricity cable tunnels that span across Singapore, we will be able to deal with the complexities of building this underground substation. With the learnings and experience gathered from this project, we can explore the possibilities of housing more substations underground.” The Labrador underground substation is part of the Urban Redevelopment Authority’s underground Master Plan 2019. The electricity substation at Labrador and the commercial building are scheduled for completion in 2024. SP today announced that it has awarded the building contract of the substation to main contractor Hyundai Engineering & Construction Co. Ltd. 1 Electrical transmission substations range between 66kV to 400kV. When running at full capacity, one 230kV substation can power up to eight towns, each the size of Toa Payoh. 2 United Nation’s Sustainable Development Goals -Ends- About SP Group SP Group is a leading utilities group in the Asia Pacific, enabling a low-carbon, smart energy future for its customers.

28 March 2013 For Immediate Release MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 APRIL TO 30 JUNE 2013 1. For the period from 1 Apr to 30 Jun 2013, electricity tariffs will increase by an average of 1.5%. In the previous 3 quarters, the electricity tariff has decreased by 2.5% in Q3 2012, 2.9% in Q4 2012 and 3.7% in Q1 2013. 2. The fuel component of the tariff for Q2 2013 is based on the average forward fuel price from 1 Jan to 15 Mar 2013. Fuel prices have been on an upward trend since Jan 2013, peaking at $127.50/bbl on 13 Feb before receding slightly in Mar. Compared to the previous quarter, the average fuel price from 1 Jan to 15 Mar 2013 had increased by 2.9%. Grid charges have also increased due to additional infrastructure investments to meet increasing electricity demand and replace ageing assets. 3. On the whole, the electricity tariff for households will increase by 1.6% in Q2 2013 from 26.28 to 26.70 cents per kWh. The average monthly electricity bill for families living in four-room HDB flats will increase by $1.43 (see Appendix 3 for the average increase for different household types). 4.
