Media Release Leveraging Digital Solutions to Future-Proof Singapore’s Energy Grid As part of Singapore’s energy transition, the Energy Market Authority (EMA), together with industry partners, have embarked on digital projects to future-proof the nation's energy grid infrastructure. There has been good progress in the development of Singapore’s first Grid Digital Twin and Distributed Energy Resource Management System, and they will continue to be developed over the next few years. These projects will serve to enhance the resilience and reliability of Singapore’s electricity grid and support the deployment of cleaner energy sources. Grid Digital Twin 2. Singapore embarked on the Grid Digital Twin in 2021 with the aim of enhancing Singapore’s grid resilience, reliability, and support the deployment of cleaner energy sources. The Grid Digital Twin, comprising two key models - Digital Asset Twin and Digital Network Twin - is a virtual replica of the physical grid network and infrastructural assets. Created in collaboration with Government agencies, industry players and academia, research and development for Singapore’s first Grid Digital Twin for the national power grid has demonstrated good progress. Digital Asset Twin 3. The Digital Asset Twin is a virtual replica of SP Group’s electricity network assets. Developed by the SP Group, in collaboration with Nanyang Technological University (NTU), the Digital Asset Twin aims to enable network operators to monitor and analyse the condition and performance of grid assets, in order to mitigate potential issues. When fully developed, it is envisaged that the Digital Asset Twin will also enable informed decisions for prioritised and timely renewal and maintenance of grid assets. 4. Through in-house digital development capabilities, SP Group has built the core of the asset dashboard as well as key Artificial Intelligence (AI) engines and algorithms to integrate with sensors in real time. The SP-NTU Joint Lab will provide components of an Asset Health system and cost-effective condition monitoring sensors. SP Group targets to deploy a pilot by 2025. As costs of sensors, digital and communication solutions reduce, they can potentially be applied to the large number of distribution assets, such as the 18,000 transformers across SP’s 12,000 substations. Digital Network Twin 5. EMA has also collaborated with partners such as S&TPPO, A*STAR’s Institute of High Performance Computing (IHPC), and TUMCREATE to develop the Digital Network Twin within the Singapore Integrated Transport and Energy Model (SITEM). With the development of the Digital Network Twin, it enables SITEM to make use of advanced modelling and simulation software to model the impact of additional Electric Vehicle (EV) demand on the grid and identify necessary infrastructure upgrades under different scenarios. This has provided insights to EMA and SP Power Grid (SPPG) on how substation capacity could be optimised to support EV charging. The Digital Network Twin is currently undergoing the next stage of translational research and development in order to deploy the developed solutions into an end-user software solution usable by EMA by 2025. The software solution will help to assess the impact of significant demand changes expected in the distribution grid as energy sector decarbonises. 6. A*STAR has also incorporated high-resolution electricity demand results obtained from the Digital Network Twin into a national-level energy systems model that aims to optimise Singapore’s long-term decarbonisation pathways. The effort has yielded positive initial outcomes through the identification of potential ways to reduce investment costs in the power sector over the next 30 years, as the nation seeks to achieve net zero emissions by 2050. EMA will also work with A*STAR and other partner agencies, through the Centre for Energy and Emissions Modelling (CE2M), to further improve long term power sector decarbonisation planning. 7. Through these initiatives, Singapore will have smarter and more efficient ways of monitoring and predicting the health of the nation’s grid assets and network. In addition, the Grid Digital Twin allows for a risk-free environment to study and test different scenarios. This will help future-proof Singapore’s power grid by ensuring that it is well-equipped to manage increasing electricity demand and changes in energy supply, while maintaining reliability in grid operations. Distributed Energy Resource Management System (DERMS) 8. Distributed Energy Resources (DERs) like solar generation systems, battery Energy Storage Systems (ESS), and Electric Vehicles (EVs) are likely to proliferate in the coming decades. This is because solar power generation and battery ESS are expected to become cheaper and more efficient, given ongoing research and development efforts as well as economies of scale. As such, it is increasingly vital to ensure that Singapore’s grid infrastructure is able to support the integration and deployment of cleaner energy sources.   9. To better optimise the management of small-scale DERs such as solar and EVs across the network, SPPG has embarked on pilot development for a Distributed Energy Resource Management System (DERMS). DERMS is a monitoring and control platform which aims to support SPPG’s network operators with real-time information and control capabilities to optimise DER connections. 10. SP Group has carried out a proof-of-concept in 2021, to explore use cases where monitoring and control of DERs could support network operations. From this first phase, monitoring and control solutions were trialled on test setup to gain first-hand experience and identify potential applications for Singapore’s context. 11. The next phase of the DERMS pilot is focused on solar forecasting and capabilities to prepare for increasing EV adoption, and will be test-bedded at selected SP substations. When fully developed, DERMS will be able to support network operators in the sustainable integration of solar and EV-related DERs into the network, while effectively managing reliability and system costs.

A digital twin is a virtual model of physical infrastructure, processes and systems that can carry out various functions such as intelligent data analysis, computer modelling and simulation and machine learning to support users in improving planning and decision-making processes. 2. The digital twin of Singapore’s national grid will comprise two key models: a. Asset Twin to optimise the planning, operations and maintenance of SP’s grid assets (such as substations, transformers, switchgears and cables). The Asset Twin is able to remotely monitor and analyse the condition and performance of assets and identify potential risks in grid operations early. This allows SP Group (SP) to make informed decisions on renewal and maintenance plans accordingly. Through in-house digital development capabilities, SP Group has built the core of the asset dashboard and the initial key AI engines and algorithms to integrate with sensors in real time. The SP NTU Joint Lab will provide components of an Asset Health system and break-through cost effective condition monitoring sensors. SP Group targets to deploy a pilot by 2025. As costs of sensors, digital and communication solutions reduce, these digital solutions can potentially be applied to the large number of distribution assets, such as the 18,000 transformers across 12,000 substations.  The Asset Twin is underpinned by five research projects awarded by the Energy Market Authority (EMA) to SP and Nanyang Technological University (NTU) under the SP Group - NTU Joint Laboratory[1]. b. Network Twin for impact assessment on grid. This uses modelling and simulations to determine the impact of additional loads (such as charging of electric vehicles) and distributed energy resources (such as solar photovoltaics and energy storage systems) on the grid. Using an advanced software framework known as the Multi Energy System Modelling & Optimisation (MESMO)[2], the Network Twin is able to provide EMA and SP with a high-level assessment of the impact of demands on the grid and any upgrades required for different scenarios. EMA and agencies such as A*STAR’s IHPC, S&TPPO, and TUMCREATE, have developed the Singapore Integrated Transport and Energy Model (SITEM) to model the impact of additional Electric Vehicle (EV) demand on the grid and identify necessary infrastructure upgrades under different scenarios. SITEM has provided insights on how substation capacity can be optimised to support EV charging. The first prototype Network Twin was developed as part of the SITEM project by the Institute of High Performance Computing (IHPC) at the Agency for Science, Technology and Research (A*STAR), together with its technology partner TUMCREATE Ltd. The project was funded by the Public Sector Science & Technology Policy & Plans Office (S&TPPO).  IHPC is currently undertaking the next stage of translational R&D that aims to deploy the Network Twin into an end-user software solution usable by EMA engineers by 2025.  EMA will work together with A*STAR and other partner agencies in the Centre for Energy and Emissions Modelling (CE2M), which seeks to support long-term national decarbonisation planning. The initiative aims to develop a federated systems architecture that integrates the national energy system model, with sectoral models such as power and transport.  The modelling effort would better inform Singapore’s net-zero strategy, including our future power grid. 3. Key benefits of the Grid Digital Twin are: a. Enhanced condition monitoring of assets and prioritisation of asset renewal, by having a decision tool that can identify risks and prioritise grid assets renewal plans. The tool will take into account health, utilisation and failure history of the grid assets.  b. Improvement in carrying out network planning analysis by having a better network utilisation when balancing new or peak electricity loads. c. Optimisation of asset investment, by identifying potential synergies between asset renewal and upgrades for load growth without compromising grid resilience.

This charge varies for different load requirements and is categorised as follows: [a) Development Without Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from both the High Tension [HT) and LT networks, which includes the cost of service cables. For individual consumers without substations, the cost of LT service cable for the same capacity may vary widely depending on their locations with respect to the nearest LT mains. These consumers are not the sole beneficiaries of the extension of the LT network. To achieve a greater degree of equity in terms of cost for these general consumers, a standard cost approach is adopted by grouping consumers with similar supply requirements. The average global cost per kVA is determined based on past statistics. For example, this category of consumers which comprises mainly landed residential owners applying for the same applied load, will pay the same standard connection charge regardless of the location of their premises from the existing LT network. [b) Development With Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from the HT network and the cost of service cable. The cost of tapping supply from the HT network refers to the cost of cables and consumables used in setting up a new distribution substation. It excludes the cost of shared network assets such as switchgear, transformer and HT network cables. The cost is spread to all new consumers proportionally on a per kVA basis. For consumers with substations, their supply intake point is usually adjacent to the substation, which requires a service cable of approximately 15m in most instances. Therefore, the standard cost of service cable is computed based on a length of 15m. Consumers shall pay the additional cost for service cable exceeding 15m. In addition, consumers shall also pay for those dedicated assets, such as switchgear and transformers, which are serving them and do not benefit others.

For longer lengths, additional charges shall apply. Standard charges are only applicable to consumers who are connected to the shared network. Standard charges are not applicable to consumers where the network extension is unlikely to be shared by others. Some of these include supply to HDB premises, premises involving installation of bigger capacity cable in order to overcome the excessive voltage drop, temporary work sites, public installations and offshore island premises. These consumers will be required to pay for the full connection network cost, based on user-pay principle, as they are the main beneficiaries. B2 Service Connection Charges for HT, EHT and UHT Supply Consumers taking HT, EHT and UHT supply shall pay the cost of the service connections to their intake equipment including cables, associated equipment and facilities to effect the connection of consumers’ equipment to SPPA’s substation/network. The service connection shall cater for single contingency. Consumers requesting for additional level of contingency that exceeds the single contingency standard are required to pay for the full cost of such provision. B3 Dedicated Network/Substation The developer or consumer shall pay the full cost of all associated equipment and facilities under a dedicated network/substation scheme for which the network capacity is intended to serve the developer’s development or consumer’s premise(s) exclusively. A substation comprises land, building, electrical equipment and associated cables. A substation which serves a development or premise has to be provided and paid for by the developer or consumer. As the capacity of electrical equipment is lumpy, the substation may have excess capacity. The developer or consumer will carry the cost of this excess capacity which cannot be avoided. As this substation is required to serve mainly the development’s or consumer’s load, it is considered a dedicated substation. To reduce cost, a developer or consumer can choose to let SPPA bear the cost of the electrical equipment and associated cables, thus making the network/substation a nondedicated one. In return, SPPA must be allowed to allocate the excess capacity to other consumers. Even after the excess capacity is allocated, SPPA shall return the capacity to the developer or consumer if his demand grows later provided existing allocated capacity to other consumers can be diverted. The latter provision shall also apply to the decommissioning of the substation. At present, most substations provided by developers or consumers are non-dedicated substations.

UCC applies to: (a) Normal customers without embedded generation; (b) Customers with embedded generation who require top-up supplies and opt to summate their kW output from embedded generation and kW demand from the network (i.e Summation Scheme) for determining maximum demand; and (c) Customers with embedded generation who require top-up supplies and opt to cap their power demand in kW drawn from the network (i.e Capped Capacity Scheme or Extended Capped Capacity Scheme). The UCC applies in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the contracted capacity and shall be limited to 20% of the Contracted Capacity. 8 For Capped Capacity Scheme (CCS), the Uncontracted Standby Capacity Charge (USCC), at 5 times of Contracted Capacity Charge, applies in the event that the demand in kW (measured by the power meter) drawn from the network exceeds 120% of the contracted capacity for a duration of more than 10 seconds continuously. 9 For Extended Capped Capacity Scheme (ECCS), the 2-tier Uncontracted Standby Capacity Charge (USCC) applies as follows: • Tier 1: 5 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 120% and up to 200% of the contracted capacity for a duration of more than 100 seconds continuously. • Tier 2: 12 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 200% of the contracted capacity for a duration of more than 10 seconds continuously. 10 For both CCS and ECCS, the consumer shall at its own expense, install and maintain Load Limiting Device, in accordance with requirements that the Transmission Licensee may stipulate from time to time. * Based on power factor of 0.85 Notes On Use-of-System Charges Effective from 1 April 2018 1 Supply Categories The Use-of-System [UOS) Charges shall be paid for electricity transmission services at each metered intake supply point in accordance with the voltage at which a consumer receives the electricity supply. The UOS Charges are applicable for the following categories of supplies : • Low Tension [LT) Supplies at 400V/230V Supply to Low Tension-Small Consumer Supply to Low Tension-Large Consumer • High Tension [HT) Supplies at 22kV and 6.6kV Supply to High Tension-Small Consumer, whose Contracted Capacity is less than 1,700 kW per month at each metered intake supply point. Supply to High Tension-Large Consumer, whose Contracted Capacity is at least 1,700 kW per month at each metered intake supply point. • Extra-High Tension [EHT) Supplies at 66kV Supply to Extra-High Tension Consumer • Ultra-High Tension [UHT) Supplies at 230kV Supply to Ultra-High Tension Consumer • Temporary Supplies Temporary Supplies apply only to LT and HT supplies for temporary civil engineering and building construction sites. 2 Low Tension Supplies 2.1 Low Tension Small Consumer LT supplies [in kWh) to all non-contestable LT consumers are metered on a monthly basis. A flat per kWh UOS rate is levied at each metered intake supply point. These are consumers who choose to buy electricity from SP Group at the regulated tariff. 2.2 Low Tension Large Consumer LT Supplies to these contestable consumers are metered on energy (kWh) on a halfhourly time-of-day basis. The respective per kWh charges shall be levied at a “Peak” and an “Off-peak” period for the energy supplied at each metered intake supply point. 2.2.1 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 2.2.2 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3 High Tension, Extra-High Tension and Ultra-High Tension Supplies For HT (i.e. HT Small and HT Large), EHT and UHT Supplies, UOS Charges shall be levied at each metered intake supply point as follows : a. Contracted Capacity Charge; b. Peak Period Charge; c. Off-peak Period Charge; d. Reactive Power Charge; e. Uncontracted Capacity Charge, and f. Uncontracted Standby Capacity Charge (applicable to consumers with embedded generation who opt to cap their power demand drawn from the network). 3.1 Contracted Capacity Charge 3.1.1 The Contracted Capacity Charge is a monthly charge payable in any month for the Contracted Capacity at each intake supply point of a consumer. The Contracted Capacity shall be the supply capacity (in kW), which is requested by the consumer for that intake supply point. For the avoidance of doubt, and without prejudice to paragraph 3.1.3 herein, the consumer shall not be allowed to reduce the declared Contracted Capacity upon the signing of the Consumer Connection Agreement / Supply Agreement, notwithstanding the fact that the energisation of the new supply has still not taken place. 3.1.2 For a new connection, consumers are subject to a binding period of 5 years from the target date or the commissioning date for SPPA’s plant and equipment, except for the service cable, whichever is later. During the 5-year binding period, no reduction to the Contracted Capacity is allowed. For new HT, EHT and UHT connections, the minimum Contracted Capacity for each intake supply point is as follows : HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 1,700 kW, 12,751 kW, 25,501 kW, 85,000 kW. During the first year of the 5-year binding period, requests for intermediate incremental steps of Contracted Capacity may be made before the full Contracted Capacity is implemented. The first step shall be at least one quarter ( 1 /4) of the consumer’s requested full Contracted Capacity at each intake supply point. 3.1.3 After the initial 5-year binding period, the consumer may, by giving at least 10 business days’ notice in writing, reduce his Contracted Capacity at each intake supply point subject to the following minimum values: HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 850 kW, 6,375 kW, 12,750 kW, 42,500 kW. Any such reduction in Contracted Capacity shall be subject to a 1-year binding period from the effective date of the revised Contracted Capacity, i.e. the consumer shall not be entitled to make any further reduction in the Contracted Capacity within one year following any such reduction. The Market Support Services Licensee will inform the consumer of the date of their billing cycle. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. 3.1.4 The consumer, may, by giving at least 15 business days’ notice in writing, may be allowed to increase his Contracted Capacity, during the 5-year or 1-year binding period. The revised Contracted Capacity shall apply for the remainder of the initial 5-year binding period or for a minimum period of 1 year, whichever is later, provided SPPA is not required to install new or additional equipment. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. Reduction of Contracted Capacity during binding periods will not be allowed. 3.1.5 A consumer whose revised Contracted Capacity requires SPPA to install new or additional equipment shall be considered as receiving a new supply with a new 5-year binding period. 3.1.6 Subject to Clause 3.1.4 and 3.1.5, the UCC incurred by a consumer in a particular month (“UCC Month”) can be converted into Contracted Capacity Charge provided: (i) (ii) (iii) (iv) The consumer submits the request for an increase in Contracted Capacity no later than 2 weeks after the date of the bill for the UCC Month; The revised Contracted Capacity is not less than the maximum demand recorded in the UCC Month; The revised Contracted Capacity does not require the Transmission Licensee to install new or additional equipment; and Upon approval by the Transmission Licensee, the revised Contracted Capacity shall take effect on the first day of the UCC Month and thereafter shall not be reduced within one year, or the remaining of the 5-year binding period, whichever is later. 3.1.7 For a new development with landlord and tenants, the Contracted Capacity required by the landlord himself and his tenants (HT and above) must in aggregate meet the minimum values set out in paragraphs 3.1.2 to 3.1.3 above in order for the landlord to qualify for HT, EHT or UHT supplies. If landlord or its tenants (HT and above) request to revise their Contracted Capacity, the aggregate Contracted Capacity after revision must meet the minimum Contracted Capacity values and subject to the same terms and conditions for revision of Contracted Capacity set out in paragraphs 3.1.3 and 3.1.4. 3.1.8 Existing HT, EHT or UHT consumers may have Contracted Capacity below the minimum Contracted Capacity as specified in paragraphs 3.1.2 and 3.1.3. For such consumers, they may request to increase (but not decrease) their Contracted Capacity in the manner as described above. 3.2 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 3.3 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3.4 Reactive Power Charge The Reactive Power Charge is a monthly charge payable in any month for the installation's excess kVArh consumption. The excess kVArh shall be the difference by which the installation's kVArh consumption drawn from the network in that month is greater than 62% of its kWh consumption drawn from the network in the same month. 3.5 Uncontracted Capacity Charge 3.5.1 The Uncontracted Capacity Charge is a monthly charge payable in any month for the Uncontracted Capacity utilised. The Uncontracted Capacity is the capacity in kW by which the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point. 3.5.2 The Uncontracted Capacity Charge shall apply to the following HT, EHT and UHT consumers : a. Normal consumers without embedded generation; b. Consumers with embedded generation whose monthly maximum demand in kW is the maximum summated demand in kW in the month, determined by summating the kW demand drawn from the network and the kW output from embedded generation (i.e. Summation Scheme); and c. Consumers with embedded generation who opt to cap their power demand in kW drawn from the network in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point (i.e. Capped Capacity Scheme or Extended Capped Capacity Scheme). The Uncontracted Capacity for these consumers shall be limited to 20% of the Contracted Capacity. 3.6 Uncontracted Standby Capacity Charge 3.6.1 The Uncontracted Standby Capacity Charge is a monthly charge payable in any month for the Uncontracted Standby Capacity utilised. The Uncontracted Standby Capacity Charge shall apply to those HT, EHT and UHT consumers with embedded generation who opt for the Capped Capacity Scheme or Extended Capped Capacity Scheme. 3.6.2 For Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event the demand in kW drawn from the network (measured by the power meter) exceeds 120% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.3 For Extended Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event : • the demand in kW drawn from the network exceeds 120% and up to 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 100 seconds continuously; or • the demand in kW drawn from the network exceeds 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.4 For the avoidance of doubt, in the event Uncontracted Standby Capacity Charge applies in accordance with Clauses 3.6.2 and 3.6.3 above, Uncontracted Capacity Charge shall also be applicable for the Contracted Capacity portion which is 20% above the customer’s declared Contracted Capacity. 4 Temporary Supplies Temporary Supplies apply only to LT and HT supplies for temporary civil engineering and building construction sites. The UOS charges applicable for the LT and HT temporary supplies shall be the same as those used for LT and HT supplies respectively. For temporary supplies at HT, the Contracted Capacity shall apply for a binding period of 2 years. Upward revision of the Contracted Capacity may be allowed during the validity of the binding period of the Contracted Capacity. The revised Contracted Capacity shall in such cases apply for a minimum period of 1 year, provided SPPA is not required to install new or additional equipment.

Introduction This section provides information applicable to solar PV generators who install solar PV systems to inject all electricity generated into the grid (e.g. solar farm). 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. September 2018 2 Solar PV – User Guide for Generators Figure 1: Overview Process for Solar PV Generators 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) Generation Capacity > 1 MWac? Yes No PowerGrid (SPPG) to evaluate and discuss with LEW on the technical requirements and specifications of the solar PV system pertaining to PQ requirements Comply with technical requirements? Consumers to sign Connection Agreement No • No Electricity Generation Licence required • Register for the applicable options available for market participation and settlement (refer to Market Settlement section for more details) • Yes SPS to inform LEW to proceed with Turn- On application • All required documents need to be submitted and approved before Turn-On. • Apply for the applicable Generation Licence (refer to Electricity Generation Licence section for more details) • Register with the Energy Market Company (EMC) to receive payment for excess electricity sold back to the grid (refer to Market Settlement section for more details) September 2018 3 Turn-On Solar PV – User Guide for Generators 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 licenses 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 System Installed Capacity of Solar PV System Below 1 MWac Connected to the Power Grid? 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. Type of Licence* 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. September 2018 4 Solar PV – User Guide for Generators 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 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. 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 is also categorised as an 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. If there is no existing electrical installation licence, the LEW shall apply for electrical installation licence for his solar PV system. 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. September 2018 5 Solar PV – User Guide for Generators 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 systems 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. You will need to sign a Connection Agreement with the Transmission Licensee for the generation connection to your PV generation facility. September 2018 6 Solar PV – User Guide for Generators The simplified connection and turn-on application process for solar PV generators are illustrated in Figure 2 and 3. Figure 2: Application Process for Solar PV Generator Connection Start Appointed LEW to submit relevant documents to SPS Consumers to sign Connection Agreement SPPG to evaluate technical specifications of the solar PV system pertaining to PQ requirements Compliance with technical requirements?

Market Settlement Similar to other commercial generators, a standalone solar PV generator is 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 export of electricity into the grid. They will be paid nodal price for the selling of solar electricity back to the grid, and are subjected to the applicable market charges. 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 (which includes PSO Standing Data Form for IGS) • Approved Connection Agreement from SP PowerAssets • Signed MSSL-MP Agreement All the documents should be approved before the solar PV system is turned on. A summary of the market payments and charges for such installations can be found in the table below. Table 2: Market Payment and Charges for Standalone Solar PV Generators Applicable Payments / Charges Energy Generation Energy Consumption Spinning Reserves Regulation Reserves (i.e. AFP) EMC Fees Power System Operator (PSO) Fees Market Support Services (MSS) Charge Description Energy Payment / Charges Nodal Price (to be paid based on net export) Uniform Singapore Electricity Prices (USEP) + Hourly Energy Uplift Charge (HEUC) (to be charged based on net import) Reserves Charges Only applicable for solar PV systems more than 10 MWac (subject to change based on the New Pricing Mechanism Framework) Half-hourly AFP (to be charged based on gross generation and gross consumption) Non-Reserves Market Charges Yearly revised EMC Fees (to be charged based on net import or net export) Daily revised PSO Fees (to be charged based on net import or net export) Yearly revised MSS Charge (to be charged based on net import only) September 2018 9 Solar PV – User Guide for Generators Applicable Payments / Charges Monthly Energy Uplift Charge (MEUC) Use of System (UOS) Uncontracted Capacity Charge (High-Tension & Above Network only) Description Monthly revised MEUC prices (to be charged based on net import only) Grid Charges Yearly revised UOS Charge (to be charged based on import channel) Cost is dependent on type of backup required 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. 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. September 2018 10 Solar PV – User Guide for Generators 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. 8. Decommissioning Requirements If you intend to decommission the entire solar PV system installed in your premises any time after they have been connected to the Transmission System, your appointed LEW will have to complete the decommissioning form and submit to SP PowerGrid Ltd at least 30 days in advance before the intended decommission commences. However, if the intent is to revise the solar PV capacity installed in your premises any time after they have been connected to the Transmission System, 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 September 2018 11 Solar PV – User Guide for Generators • 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 systems 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) September 2018 12 Solar PV – User Guide for Generators 9.

With effect from 1 October 2016, Singapore Power Limited and its Singaporeincorporated subsidiaries (SP Group) has implemented the SP Group’s Contractor Performance Management System (CPMS) to strengthen its partnership with and improve the safety and quality performance of its contractors. 2. Through the CPMS, SP Group aims to take a holistic approach to the selection of its contractors as part of enhancing procurement process, by looking at the performance of its contractors at a quarterly and annual basis and not only based at performance at each individual contract basis. The previous demerit scheme in respect of each contract will be abolished while an incentive and mitigation scheme that goes towards enabling contractors to improve their performance on a longer term basis is now implemented. Objectives 3. The objectives of the CPMS are: (a) (b) (c) to adopt a more holistic approach in reviewing contractors’ overall performance; to work with contractors to raise safety and quality standards; and to encourage an environment of continuous improvement by contractors. 4. In order to achieve the above objectives, CPMS will utilise the following 3 main components: (a) (b) (c) Contractor Performance Assessment (CPA); Business Under Surveillance (BUS) Programme; and Tender Evaluation Framework (TEF). SP Group CPMS V6.0 19 Jul 2023 1 Applicability 5. The CPMS will be applicable for procurement in relation of the following services and works: (a) (b) (c) (d) (e) (f) cable installation, cable jointing and road reinstatement; gas pipe-laying; milling and patching; transmission cable-laying; building and construction; and other road opening-related works (e.g., manhole access works). SP Group intends to broaden the scope of the CPMS to eventually apply the CPMS for procurement of other engineering-related works and services. 6. The CPMS will apply to contracts awarded on or after 1 October 2016 and any ongoing contracts which fall in any of the above categories set out in paragraph 5. All aspects of the CPMS, such as the BUS Programme and rewards and mitigations, will apply to such contracts. Contractor Performance Assessment 7. For each contract, a contractor will be assessed by the relevant SP Group project team in the following four (4) areas: (a) (b) (c) (d) Safety. Quality of Work; Project & Risk Management; and Value Added Services. These scores for each contract (Contract Quarterly Score) will be tabulated at fixed quarterly basis. The individual Contract Quarterly Scores applicable for each contract will then be averaged to derive the Contractor Quarterly Score. SP Group CPMS V6.0 19 Jul 2023 2 The criteria have a direct impact on risk mitigation which helps to review the way work activities are planned and executed. The objective of the enhancements is to reduce risk and improve safety at work sites. The PSR shall review the risk identification and mitigation measures to be taken during the design & construction for all contracts within SP Group. Emphasis will be given to the PSR communication to workers through the Risk Management workshops on site. ABSIS will be used to engage with the worker level to improve work processes and create a safer environment to work in. SP Group will assess the contractors’ senior management engagement with their workers through various in-house activities. 8. Examples of the factors taken into consideration in determining the individual Contract Quarterly Score are as follows Safety • Safety Performance • Site Safety Management • Safety Engagement by Management • Project Safety Review (PSR) • Risk Management workshop • Activity Based Safety Improvement System (ABSIS) Quality of Work • Documentation • Workmanship • Any damage to properties Project & Risk Management • Incident management • Cooperativeness • Meeting schedules Value Added Services • Initiatives to improve productivity and efficiency SP Group CPMS V6.0 19 Jul 2023 3 9. In addition to the above criteria, SP Group will also take into account the occurrence of any Critical Incidents when determining the Contractor’s Quarterly Score by applying a corresponding adjustment factor to their score. (a) The Critical Incidents includes: Critical Incidents Smoking or open flame in gas installations and electricity transmission substations Not adhering strictly to isolation procedures for live electricity or gas equipment and machinery at site Damage to Transmission Cables / Gas Pipes Damage to Distribution Cables / Gas Pipes Not anchoring safety harness while working at heights exceeding 3 metres Working in a confined space without conducting mandatory gas check Working under suspended load during lifting or excavator operations Fatality or serious injury Where Serious Injury is defined as: Serious Injuries Loss of 2 limbs Loss of both hands or of all fingers and both thumbs Loss of both feet Total loss of sight, including the loss of sight to such extent as to render the employee unable to perform any work for which eyesight is essential Total paralysis Injuries requiring more than 20 days of hospitalization. (Hospitalization refers to the period where injured remains warded in a hospital) Loss of arm at shoulder Loss of arm between elbow and shoulder Injuries resulting in being permanently bedridden Loss of arm at elbow Loss of arm between wrist and elbow SP Group CPMS V6.0 19 Jul 2023 4 Loss of hand at wrist Loss of 4 fingers and thumb of one hand Loss of 4 fingers Loss of leg • At or above knee • Below knee Loss of foot Loss of sight of one eye Total loss of hearing (b) The Serious Incidents includes: Serious Incidents Damage to Distribution Cables/ Gas pipes affecting less than or equal to 300 customers Damage to Public assets (e.g., PUB pipes, streetlights) Note: Contractors shall not be penalised for damages to the public assets if it was unavoidable due to Authorities’ drawings that provided inaccurate factual information and the Contractor’s detection works did not provide better information. 10. At the end of each quarter, SP Group will provide each contractor a grade relative to their score to provide them timely information on their performance. The names and grades for each contractor scored in each quarter shall be available on the SP Group corporate website. 11. In the event the Contractor’s Quarterly Score is lower than 50, the contractor will be suspended from participating in any new procurement activities for the next 3 months. In the event of an occurrence of a fatality or serious injury at his work site, the main contractor and its subcontractor will be suspended from participating in any new procurement activities for 12 months from the incident date. The suspended contractors and their subsidiaries are also not allowed to apply to be sub-contractors for any SP Group contracts during the suspension period. SP Group CPMS V6.0 19 Jul 2023 5 12. The Contractor Quarterly Scores will be aggregated on an annual basis [Contractor Annual Score]. Contractors must have at least two (2) Contractor Quarterly Scores to be included for the Contractor Annual Score computation. 13. At the end of each Assessment Year, the 5 contractors with the highest Contractor Annual Score for the year will be given an incentive of 2% of the total annual value of their respective contracts capped at $100,000.00 per year per contractor. The annual value of each contract is computed as follows: where: ACV is the annual value of a contract; ACV = A X B A is the Contract Sum divided by the Contract Period [weeks]; and B is the number of weeks [or part thereof] where Works carried out in that year under that contract. 14. The 2 contractors with the lowest annual scores will be subjected to a penalty deduction to their PQS scores in all subsequent SP Group tenders published during the next Assessment Year. In addition, they would also have to comply with performance improvement requirements specified by SP Group to address areas of deficiency. SP Group CPMS V6.0 19 Jul 2023 6 Business Under Surveillance (BUS) Programme 15. The BUS Programme is an educational and correctional tool aimed to partner contractors to address safety and quality issues encountered by contractors in the course of their work for the SP Group and in the longer term help improve their safety and quality standards. The BUS Programme and will be activated in the following situations: (a) (b) Occurrence of any Critical Incident; and/or 3 or more safety inspections at the project sites where major safety-related non-conformances (safety non-conformance) are observed. 16. In the event of the activation of the BUS Programme, the Contractor will be required to undergo the activities as follows: 17. Stopping work at the affected site[s] during a BUS Programme is important to allow contractors to review its safety practices and focus on its operational methods and processes with the aim of preventing further incidents from occurring again. 18. If the contractor placed on a BUS Programme is unable to meet the exit requirements at the end of the 5 th week, a further 2 weeks extension will be granted. If the contractor is still unable to meet the exit requirements at the end of the 7 th week, the contractor will be placed on a second BUS Programme to address the failure of the first BUS Programme. SP Group CPMS V6.0 19 Jul 2023 7 19. In the event the contractor is placed on the BUS Programme more than 2 times in a calendar quarter, the contractor will be suspended from participating in any new procurement activities for the next three months. The suspended contractors and their subsidiaries are also not allowed to apply to be sub-contractors for any SP Group contracts during the suspension period. 20. From 1 Apr 2023, Contractor shall not be under MOM’s Business Under Surveillance programme (BUS) OR not accumulated 25 or more demerit points under MOM’s DPS as at the Tender Closing Date and before the Tender Award Date. Tender Evaluation Framework 21. The CPMS adopts a tender evaluation framework that comprises the following 3 Stages: 22. Stage 1 (SET) aims to inculcate a mindset of safety being the highest priority among our contractors, by selecting only likeminded contractors who have adequate safety management system and track records to work on our projects. Contractors who meet the SET requirements will be pre-qualified to participate in SP Group’s tenders for works described in paragraph 5 above. Once such pre-qualification is granted by SP to the contractors, it shall be valid for the entire Assessment Year. Any contractor which fails the Stage 1 assessment can apply for re-assessment at the start of new calendar quarter after being notified of its failure to pre-qualify. SP Group CPMS V6.0 19 Jul 2023 8 23. In the subsequent Stage 2 and 3 of the evaluation of bids submitted for CPMS applicable tenders, each bidder’s Contractor Quarterly scores over the past 2 years will be taken into account to determine the successful bidder. Where a bidder does not have sufficient records of past Contractor Quarterly Scores (e.g. new contractors) a default score will be used instead. Amendments and FAQs 24. SP Group may modify the CPMS at any time and such amendments shall be deemed immediately applicable to the contracts that are ongoing at the time of such amendments. Contractors are strongly encouraged to check https://www.spgroup.com.sg/doing-business-with-us/procurement for amendments, updates and FAQs relating to the CPMS. 25.

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.
