Introduction This section provides information applicable to non-residential consumers with embedded solar PV systems to reduce their electricity consumption. A brief summary of the relevant processes can be found in the flow chart on the website. 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. December 2022 2 Solar PV – User Guide for Non-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 Yes No 1 MWac or more but less Yes than 10 MWac 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 Non-Residential Consumers All electrical work for an electrical installation, including a solar PV system, must be undertaken or carried out by a Licensed Electrical Worker (LEW). 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 LEW will need to apply for an Electrical Installation Licence for the installation if the usage or operation of an electrical installation exceeds 45 kVA of approved load for non-domestic purposes and for multi-metered premises. Electrical installations are licensed to ensure that owners/users of certain electrical installations engage a LEW to take charge of and maintain their electrical installations for reason of safety. A grid-connected solar PV system forms part of the consumer’s electrical installation. A new solar PV system will be covered under the existing electrical installation licence upon connection to the installation by the LEW taking charge of the electrical installation. Safety requirements Currently under the electrical installation licensing scheme, the consumer’s appointed LEW is required to carry out safety inspection and certification of the electrical installation, including the solar PV system, according to the conditions specified under the electrical installation licence. Solar PV systems require 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 the LEW. December 2022 4 Solar PV – User Guide for Non-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) • Certificate of Compliance (only applicable for licensed installation who are eligible to appoint their LEW to commission the solar PV system) • Commissioning Declaration (only applicable for licensed installation who are eligible to appoint their LEW to commission the solar PV system) Thereafter, your appointed LEW will have to consult SPPG on the connection scheme and technical requirements. For High Tension and above (6.6kV and above) consumers with embedded IGS / generation, you will need to choose one of the 3 backup schemes (full or partial) required: (1) Summation Scheme; (2) Capped Capacity Scheme; or (3) Extended Capped Capacity Scheme You will need to sign a Supplemental Agreement with the Transmission Licensee to reflect your choice of backup scheme for the service connection. For more information on each scheme, please refer to SPPG’s guide on “How to Apply for Electricity Connection” available on the SP Group website (www.spgroup.com.sg).

Market Settlement The process required and the amount of payment received for selling excess solar electricity back to the grid depends on the size of the solar PV system and contestability status of the consumer. An overview of the available payment schemes can be found on EMA’s website. Consumers with embedded solar PV systems will be given ‘net settlement’ of the energy component. This means that consumers are either charged for their net consumption or paid for their net generation within each trading period. 5.1 Solar PV system below 1 MWac Non-contestable consumers (NCCs) For Low Tension (LT) NCCs with less than 1 MWac embedded solar PV systems, 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 tariffs can be found on SP Group’s website (www.spgroup.com.sg). Contestable consumers (CCs) For CCs who wish to be paid for the excess electricity sold to the grid, they can register with SPS under the Enhanced Central Intermediary Scheme (ECIS). Under this simplified arrangement, they will be paid the weighted average nodal price through SPS, for the selling of excess solar electricity back to grid. SPS will act as a central intermediary, by passing through the payment and relevant market charges to 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 8, 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. For CCs who do not wish to be paid for the excess electricity sold to the grid, they do not need to register with EMC as Market Participant or with SPS under the ECIS. They 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. December 2022 10 Solar PV – User Guide for Non-Residential Consumers will not be eligible for the ‘net settlement’ scheme and also not be subjected to the applicable market charges. 5.2 Solar PV system 1 MWac and above but below 10 MWac There are various options for CCs to sell excess electricity back to the grid: i. Register with SPS under the Enhanced Central Intermediary Scheme. Under this simplified arrangement, they will be paid the weighted average nodal price through SPS, for the selling of excess solar electricity back to grid. SPS will act as a central intermediary, by passing through the payment and relevant market charges to 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 8, AMI Meter Charges. For option (b), the solar generation will be estimated based on the SGP for the calculations of the relevant payment and market charges. Consumers need not install any meters. ii. Register with the EMC as Market Participant. Under this existing arrangement, the CCs are required to register with the Energy Market Company (EMC) as Market Participant (MP); and to register their Solar Generation Facility, in order to receive payment for the selling of the excess solar electricity back to the grid. They will be paid nodal price for the selling of excess solar electricity back to the grid, and are subjected to the applicable market charges. 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 8, AMI Meter Charges. For option (b), the solar generation will be estimated based on the SGP for the calculations of the relevant payment and market charges. Consumers need not install any meters. The required registration documents can be found below. Market Participant Registration • MP Registration form • Signed PSO-MP Agreement and Generation Facility Operating (GFO) Agreement with PSO (if applicable) Generation Facility Registration • The Generation Facility Registration form • Approved Connection Agreement from SP PowerAsset • Signed MSSL-MP Agreement December 2022 11 Solar PV – User Guide for Non-Residential Consumers All the documents should be approved before the solar PV system is turned on. iii. Register with EMC as Market Participant (IGS non-exporting). For consumers with embedded solar PV systems below 10 MWac who are not eligible for option (i) or (ii) and will not be selling any electricity back to the grid, they can undergo a streamlined market registration process and pay EMC an estimated fixed charge determined by EMA. This fixed charge will be based on the SGP and the historical average rates of the respective charges. For options (i) and (ii), CCs would need to register their load and generation accounts under the same entity with SPS. A summary of the market payments and charges for the respective options can be found in the table below.

For example, on a rainy or cloudy day, they will be consuming more electricity from the grid as their solar PV system may be generating little or no electricity. However, as the SGP is a fixed output throughout the year, it would indicate that the solar installation is still generating. Hence, before deciding on the type of backup scheme and whether to opt for SGP or meters, consumers should assess their consumption profile and operational needs. They should also consider carefully the costs and benefits, including the risks and uncertainties due to weather variability. Reactive Power Currently in the Transmission Code, High-Tension consumers would be required to implement power factor correction measures, if deemed necessary by the Transmission Licensee, to maintain a power factor of no less than 0.85. This is because a load with high reactive power will require more current-carrying capacity from the grid. For solar consumers who opt for SGP, there may be instances where they are penalised due to differences between active power output based on the SGP and active power output based on actual generation. This affects the calculation of gross load, on which reactive power penalties are determined. Hence, consumers who opt for SGP may risk incurring reactive power penalties when actual generation values differ from SGP values. If so, consumers can opt out of the SGP and install physical meters to accurately measure the active power output. 6. Intermittency Pricing Mechanism Given the intermittent nature of solar PV, reserves from conventional power sources are required to ensure system stability. For example, cloud cover or shadows may cause solar PV output to drop quickly, which requires the need for reserves to make up for the shortfall. Without the back-up through reserves sources, consumers are exposed to the risk of power disruptions, which happened in other countries with large amounts of intermittent generation. December 2022 15 Solar PV – User Guide for Non-Residential Consumers To ensure the sustainable growth of solar, a balance has to be struck between the benefits of solar generation and the intermittency costs it imposes on the system. Hence, it is appropriate to consider a mechanism, Intermittency Pricing Mechanism (IPM), to allocate the fair share of reserves costs to solar. Upon its implementation, the IPM will apply to all IGS, except for certain groups which the EMA had previously indicated that would not be subject to the IPM. The groups include: a. Residential consumers with embedded solar PV systems below 1 MWac; and b. Non-residential consumers with embedded solar PV systems connected to the system on or before 31 January 2018, unless (i) they retrofit their IGS systems such that re-commissioning by SP PowerGrid would be required in the process; or (ii) 25 years from the commissioning date of their existing IGS systems, whichever occurs earlier. More details on the IPM can be found in EMA’s Consultation Paper. 7. 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_EMS@ema.gov.sg. Localised Network Limit As there may be physical constraints of each network ring, there could be a limit to the amount of solar PV systems that the network circuit can support. Therefore, depending on the limitations in that area, the permissible capacity of solar PV systems in each location may differ. Hence, parties who wish to invest in solar PV systems should check if there are possible network constraints in their preferred locations, before making their investment decisions. December 2022 16 Solar PV – User Guide for Non-Residential Consumers 8. AMI Meter Charges This section is only applicable to consumers who register their embedded solar PV systems with SPS under the Central Intermediary Scheme, or with EMC as a Market Participant. 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 tables below: Table 4.1: Metering Charges for Generation Meters (inclusive of 7% GST before 1 st Jan 2023) Per Generation Unit / Metering Point Main & Check Meters At 66kV and above Main & Check Meters At 6.6kV / 22kV Main & Check Meters At Low Tension Main Meters Only At Low Tension Upfront charge (One time) $5,938.50 $5,938.50 $2,247.00 $1,498.00 Monthly charge (Recurring) $214.00 $85.60 $42.80 $21.40 Miscellaneous charge a) Attending to request for site enquiry during office hours (minimum 3 hours per request). b) Attending to communication / meter failure during office hour.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Making the Right Connections RELIABILITY When Van Koh received a pre-owned computer at the age of 12 from his aunt, it promptly made its way to a neat pile of “treasure”. It heralded what would become both a passion and a career for young Van – and he eventually converted a nook in his family’s four-room flat into a “workshop” to house more such treasures. His enthusiasm would eventually win him an SP Group Nithiah Nandan Polytechnic Scholarship in 2015 to study electrical engineering at Ngee Ann Polytechnic. “I’ve always liked learning how things tick, and figuring out how to make them work even better,” says the 26-year-old, now the youngest cable jointer in SP Group’s Electricity Operations department. High voltage passion: Van (bottom) maintains transmission overground boxes such as the one above with his fellow cable jointer Mohammad Rosman B Abdul Wahab. As part of an 18-man team, Van maintains and repairs extra high voltage power cables that connect the transmission network, a key component of Singapore's grid. The team is also on 24-hour standby in case of any transmission network emergency situation. The transmission network transports electricity from the generation plants to our transmission substations across Singapore before the power is distributed to customers. Therefore, it is imperative to maintain a top-notch transmission network to prevent network disruptions.  But maintaining the cables and connecting them is hard work – a single cable can be as wide as a human palm and has a complex internal structure, and the length of a circuit can be up to 30 km. “These are large, high-voltage cables with many layers. It is hard work that is hands-on, and can easily take several days. But we need to make sure all the elements within the network function well to prevent an outage.” It takes a four-man crew, excluding a cable engineer who cuts off power supply so the men can work safely, to get the job done. And the men often have to get down into the trenches – literally – since most cables are underground. Hands on: Getting down to business doing cable jointing in the trench with his colleagues Krishnasamy Shanmuguraj (left) and Sanjay Kumar (right). “You get very used to working in confined spaces,” says Van. But working in close quarters forges tight bonds and means Van – surrounded by men who have been in the job for 30 to 40 years – has no shortage of mentors. “They are like my uncles. They explain things I don’t understand but also give me life lessons when we makan (Malay for eat),” he says. In fact, it was at the urging of these “uncles” that, two years into the job, Van enrolled for a degree course in electrical and electronic engineering at the Nanyang Technology University. He graduates in 2021, having chosen to study at night and keep his day-job. “At school, you learn a lot of theory. Work gives me the hands-on exposure you cannot find in books. That’s really important to me… and I enjoy that,” he says. Even in his free time, the tinkering continues in his home “workshop”. Some of the inspired creations that emerged from that space include a fitness robot instructor for the elderly for his final-year polytechnic project and parts for his remote control planes. It was also there that, with his colleagues, he developed a prototype device that will improve safety and productivity in his line of work.  In January this year, the prototype won first prize in SP’s intrapreneurship competition. “When I look at all the work that goes into maintaining the network, and how my colleagues really put their hearts into the job, it inspires me to want to make things better, and to keep getting better at what I do.” The winning team: Van (centre) with his colleagues were the winning team in SP’s intrapreneurship competition held earlier this year. — 28 August 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ How this 'grid doctor' maintains the health of Singapore's electricity network so everything stays on Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation The Doctor Is In: Grid Health Checks Prevent Issues RELIABILITY Reading the “pulse” of network equipment, Senior Engineer Dr Lai Kai Xian can tell whether insulation material within the equipment may be breaking down. Like any good physician, Dr Lai Kai Xian is skilled in being able to look, listen and feel. The key difference is that his patient is Singapore’s electricity network, and he diagnoses the grid’s health conditions and fixes these even before they become problems. The 35-year-old electrical engineer is one of eight specialists in the SP Group’s Condition Monitoring team who keeps a close eye on the 11,000 substations and over 28,000km of cables that make up the grid. They are supported by 44 technical officers and technicians who conduct regular health screenings of all equipment on the network, and recommend deeper investigations or treatment when necessary.  Condition Monitoring Senior Engineer Dr Lai Kai Xian uses devices that require various senses – hearing, sight and touch – to assess equipment health, much like a medical doctor. Technicians take the network’s temperature using thermal guns, and listen for abnormal sounds using sensors coupled with headsets that make high frequency sounds audible. Special probes listen for the “pulse” of the equipment, and normal sounds need to be distinguished from ones that could indicate a potential problem. Sounds called transient earth voltage signals could point to internal voids in liquid, air or solid insulation material that are wrapped around cables. These kinds of “partial discharge” summon more varied equipment to pinpoint the source of an abnormality, and allow for early intervention. “These markers tell you where more investigation is needed or where problems could potentially lie so they can be solved before they get any bigger,” explains Dr Lai. He had focused his PhD studies on condition monitoring, and thanks his parents for the opportunity to have done so in Australia. SeniorEngineer Dr Lai Kai Xian (left) with his parents (right) at the 2010 University of New South Wales graduation ceremony. He was awarded a Doctor of Philosophy in Electrical Engineering. Like any emergency room, the most critical cases are attended to first, and more tests can be ordered to make a more accurate diagnosis. It can sometimes make for an intense work day, he concedes. But until his first child arrives in October, the grid is his baby – indeed his personal hobbies include reading technical articles about power systems and new technologies. Condition monitoring affords the grid an additional layer of insurance over scheduled maintenance, making it even more reliable, says Dr Lai. According to Dr Lai, an average of 70 potential problems have been avoided each year over the last five years. And unlike scheduled maintenance work which may require a piece of equipment to be taken out of service to be checked, repaired, or replaced, this pre-emptive approach is non-invasive, requiring no shutdowns. In the long run, keeping the health of a piece of equipment in check also means it lasts longer, he says. More companies are now catching on to these benefits, says Dr Lai, adding that he had trouble finding a job specifically in condition monitoring until he joined SP, a big believer in “preventive medicine”. Online monitoring is also continuously leveraged by SP for the larger 400kV and 230kV substations that make up Singapore’s transmission network, with sensors transmitting real-time data to Dr Lai’s lab. New technologies that can make the grid more robust are also regularly assessed, adds Dr Lai, also a “doctor-on-call” for casual queries from other departments, thanks to friendships forged with colleagues through weekly badminton sessions. Getting to the root of the problem is one of the things he relishes most about his role in SP’s network reliability, especially since diagnosis can be as much of an art as a science, and prompts spirited debates. “You need to be able to look beyond the obvious with data. Every single case is different, requiring both tools and thinking. That is the challenge that I love.” — 13 June 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ How this 'grid doctor' maintains the health of Singapore's electricity network so everything stays on Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing
