Media Release SP Group Launches One Of The World's First Blockchain-Powered Trading Of Renewable Energy Certificates City Developments Limited and DBS Bank on board as first buyers of certificates Enables local and international organisations – regardless of size, business or location - to meet their sustainability targets Singapore, 29 October 2018 - SP Group (SP) launched one of the world’s first blockchain-powered renewable energy certificate (REC) marketplace at the ASEAN Energy Business Forum (AEBF) on Monday, 29 October 2018. In conjunction with the launch, AEBF forum participants saw screenshots of the first purchases by buyers, City Developments Limited (CDL) and DBS Bank (DBS). Designed and built in-house by SP’s team of digital energy experts, this marketplace enables local and international organisations – regardless of size, business or location in the world – to trade in RECs. The unique attributes of blockchain technology will ensure the security, integrity and traceability of each REC transaction. This will drive the greater integration of renewable energy sources on the electricity grid. Launching the marketplace innovation at the opening session of the Forum on Monday 29 October 2018, SP’s Chief Digital Officer, Samuel Tan, said, “Through blockchain technology, we enable companies to trade in renewable energy certificates conveniently, seamlessly and securely, helping them achieve greener business operations and meet their sustainability targets.” The SP REC marketplace supports local, regional and international RECs. It also supports different supply options including types of sellers and renewable energy sources. SP announced that local organisations such as CDL and DBS, who are keen drivers of sustainable solutions, have signed on as REC buyers. Solar developers such as Cleantech Solar Asia and LYS Energy Solutions, with local and regional solar assets, have signed a collaboration with SP to place their solar assets on the marketplace for sale of RECs. Katoen Natie Singapore, a global chemical logistics company who will be launching Singapore’s largest single unit rooftop solar facility at a warehouse, has also come onboard as a REC seller. When companies purchase RECs, they are consuming electricity from renewable sources, sold to them by other companies that produce green energy. With SP’s blockchain-powered marketplace, buyers are automatically matched with sellers, around the globe, according to their preferences. This helps big and small organisations to achieve their green targets and strengthens cross-border sustainability efforts with SP’s international reach. It contributes to Singapore’s low carbon targets, as part of its Paris COP-21 agreement. Annex A Hear from our Partners “As a green advocate for over two decades, CDL has always been committed to embracing technology and solutions that reduce environmental impact.

Media Release SP GROUP SETS UP FIRST ZERO-EMISSION BUILDING POWERED BY GREEN HYDROGEN IN SOUTHEAST ASIA Singapore, 30 October 2019 – SP Group (SP) has established the first zero-emission building in Southeast Asia that is powered by green hydrogen. Located at SP’s training centre at Woodleigh Park, the self-sustaining building is 100% powered with renewable energy via an innovative Hydrogen Energy System and is disconnected from the national electricity grid. Mr Brandon Chia, Head, Centre of Excellence, SP Group said: “Buildings contribute 40 per cent of energy related carbon emissions worldwide 1 . The Hydrogen Energy System provides a safe and compact way of storing green hydrogen which powers the region’s first zero-emission building. We believe this can be a significant contributor toward Singapore’s climate change pledge to cut national emissions intensity by 36 per cent below 2005 levels by 2030.” The challenge to achieving zero emission The world in its fight against climate change is using various means to lower carbon emissions. One way is to use renewable energy sources. However, in urban places such as Singapore, due to limited land and inconsistent solar energy, achieving zero emission with 100% renewable energy is extremely challenging. Zero-emission solution An alternative is hydrogen as a green energy source. In the Hydrogen Energy System used by SP, electricity from green sources, such as solar, is used to conduct electrolysis. The hydrogen generated from this process is bonded with special metal alloy powders to form metal hydride, compacted and stored in tanks. When electricity supply is required, the stored hydrogen from the metal hydride tanks is slowly released and converted to electricity via fuel cells. As green energy sources are used for electrolysis, this entire process of converting hydrogen to electricity is 100 per cent green, with zero carbon emission. 1 The buildings and building construction sectors combined are responsible for nearly 40% of total direct and indirect CO2 emissions (International Energy Agency). 1 Safe hydrogen storage While there have been other energy systems using hydrogen as a fuel, the key challenge of hydrogen lies in having a storage solution that is safe for deployment in highly-urbanised areas such as Singapore. The system uses special metal alloy as a storage medium to bond with hydrogen. This allows for the storage of a large volume of hydrogen at a much lower pressure over a long period of time without any deterioration. When electricity is needed, the stored hydrogen is released in a slow and regulated manner, making it safer and more compact to be stored in an urban setting. Encourages greater mix of renewable energy The Hydrogen Energy System can mitigate electricity supply fluctuations and intermittency issues – common shortcomings of renewable energy. When there is surplus renewable energy, it can be stored in the form of hydrogen and converted back to electricity when there is a deficit of renewable energy. This ensures that the grid remains stable even with a greater mix of renewable energy introduced, hence encouraging the use of green energy. SP is working with Marubeni Corporation and Tohoku University on the Hydrogen Energy System with special metal alloy storage tanks from Japan, and to customise and integrate it for use in Singapore. -Ends- 2 About SP Group SP Group is a leading energy utilities group in the Asia Pacific.

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.
