Introduction This section provides information applicable for residential consumers with embedded solar PV systems (i.e. consumers who install solar PV systems on their rooftops to reduce their electricity consumption). A brief summary of the relevant processes can be found in the flow chart below. Please refer to the following sections for more information. For more information on the policy and regulatory framework for solar, please refer to EMA’s website. Figure 1: Overview Process for Residential Consumers with Embedded Solar PV Systems Start Solar PV owner to engage Licensed Electrical Worker (LEW) to be responsible for the electrical works associated with the solar PV system Appointed LEW to submit the required documents to SP Services (SPS) (refer to Connection Requirements section for more details) No SP PowerGrid (SPPG) to evaluate and discuss with LEW on the technical requirements and specifications of the solar PV system Comply with technical requirements? SPS to inform LEW to proceed with Turn-On application • For those register under the “Enhanced Central Intermediary Scheme”, SPS will arrange for opening of account after Turn-On. • For those register under the “Simplified Credit Scheme”, SPS will arrange to effect the scheme after Turn-On. 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. December 2022 5 Solar PV – User Guide for Residential Consumers Figure 2: Application Process for Solar PV System Connection Start Appointed LEW to submit relevant documents to SPS SPS to inform LEW (via Letter) to proceed with Turn-On Application SPPG to evaluate technical specifications of the solar PV system pertaining to PQ requirements Compliance with technical requirements? Yes No LEW to re-submit technical requirements after clarification LEW to proceed with Turn-On Application (refer to Fig 3 for Turn-On application process) End SPPG sends technical assessment completion letter to LEW End December 2022 6 Solar PV – User Guide for Residential Consumers Figure 3: Turn-On Application Process for Solar PV System Start LEW to submit Turn-On application to SPS LEW to arrange with Meters Section to install meters SPS to witness the commissioning of solar PV system on the scheduled Turn-On date End 5. 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.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Electricity’s First Responders RELIABILITY SP Group’s Principal Engineer Jerome Choong is one of the first at the scene should an electricity disruption happen. Five-year-old Jovan thinks his father Jerome Choong, an SP Group Principal Engineer, is a cross between an electrician and a magician. “He thinks that when people have no electricity, they call me, and I make it appear,” laughs the 35-year-old, who takes care of the electricity distribution network in the north zone, which spans the area stretching from Boon Lay to Punggol. “Jovan used to get annoyed when I left abruptly during family gatherings. Now, he is proud of what I do,” says Jerome who also has a two-year-old son. Principal Engineer Jerome Choong (right) and son Jovan Jerome has been with SP for seven years and leads a unit of 30. He is one of the first on site when an outage happens. His priority is to work with his unit to quickly and safely get supply back up. While prevention is key and every effort is made to keep trouble at bay, it is important to be prepared for the unexpected. It helps the team spring into action without delay should something happen. His car boot is testimony to his commitment – half holds a stroller for his two-year-old, and the other half, the tools he needs, from cable insulation testing equipment to multi-meters. His iPad stores documents, schematic drawings and operations manuals. His network of fellow engineers is a Whatsapp message away. Always on the alert, Jerome forms his recovery plan as he drives to the site where an incident has occurred, helped by information on the location, number of customers affected, and the substations and breakers he should zoom in on. This is provided by the Electricity Service Centre and Distribution Control Centre, which he works closely with. Principal Engineer Jerome Choong checking on switchgears in a substation. For every incident, he and his colleagues investigate what went down, isolate and test the equipment, and start on repairs or replacements. “We explore every what-if scenario,” Jerome says, “and have back-ups to the back-up plans.” While the control centre can remotely resolve some issues, manual intervention by Jerome’s team is sometimes required, and checks are always done before supply sources are switched to ensure safety. Replacement parts are also tested before being connected and energised. Only then is the power transferred back on to customers. Work does not end when an issue is resolved, and even a late-night activation often sees him back on duty the next morning. In the day, Jerome oversees the maintenance of the switchgears and transformers of the high-voltage network. He also regularly engages commercial and industrial customers with higher electricity consumption requirements. The job keeps him on his toes, he says, as does the need to evolve with his role. The rise of renewables, for one, has meant having to integrate non-traditional sources of electricity onto the grid. “I love solving problems, and we seldom encounter two situations that are exactly the same. We’re constantly learning, and re-learning. That’s what keeps the job interesting.” (From left) Principal Engineer Jerome Choong with Service Technicians Hasly Bin Hashim and Mohammad Iskandar bin Sapari attending to an incident at an affected substation.
