News Release JTC AND SP GROUP TO DEVELOP AND OPERATE SINGAPORE’S FIRST SMART GRID FOR BUSINESS PARKS AT PUNGGOL DIGITAL DISTRICT Partnership will help the District optimise energy consumption, reduce carbon footprint and save cost for businesses and consumers Singapore, 31 October 2018 – A Smart Grid system that provides green energy and increases energy efficiency will serve businesses and consumers in the upcoming Punggol Digital District (PDD). JTC and SP Group signed a Memorandum of Understanding (MOU) to collaborate on the Smart Grid at the Asia Clean Energy Summit 2018 today, witnessed by Minister for the Environment and Water Resources, Mr Masagos Zulkifli. This partnership will drive the design of smart energy solutions comprising the areas of renewable energy and electric mobility, that will be integrated with the Open Digital Platform in the District, announced in July this year. 2. Under the MoU, JTC and SP Group will develop and implement a Smart Grid within PDD. Companies in PDD can look forward to adopting clean sources of energy, such as solar energy generated from building roofs, and take advantage of new technologies, such as electric vehicle charging and smart metering. Through the Smart Grid, about 1,700 tonnes of carbon emissions could be reduced per year, equivalent to taking 270 cars off the road. 3. The Smart Grid will be integrated with the Open Digital Platform, allowing communication and interaction with other building systems in the District, such as the District Cooling System (DCS) and the Building Management System (BMS). For instance, on a hot sunny day, the Smart Grid will register an increase in electricity consumption as the air conditioning systems consume more energy to maintain the temperature in the building. It automatically sends a signal to the Open Digital Platform, which detects the specific rooms where the temperature has increased. The Open Digital Platform then activates the Building Management System within the building to lower the blinds in those rooms, reducing heat gain and conserving energy. 1 4. JTC’s Assistant Chief Executive Officer, Mr. David Tan, said, “Beyond utilities and technologies, it is about giving the community the data and tools to make informed decisions about their energy consumption, be it adopting clean sources of energy or optimising usage to reduce costs. Aggregated data on energy consumption from the Smart Grid will be made available for academics, researchers, start-ups and enterprises to encourage innovation in the domains of clean energy and energy management.” 5. Mr Goh Chee Kiong, Head, Strategic Development of SP Group said, “SP Group is committed to design and implement smart energy solutions, driven by our deep energy integration and digital capabilities. We are pleased to work with JTC to help businesses in the Punggol Digital District save cost and go green through our innovative smart grid.” 6. At the forefront of Singapore’s Smart Nation push, PDD is envisioned to be a vibrant and inclusive district where cutting-edge technology and social innovation transform the way we work, live, learn and play in the future. PDD will house key growth sectors such as digital and cybersecurity, and will also be the first district in Singapore to be fully integrated with Internet of Things systems from the ground up. This infrastructure will create conducive testbed environments for businesses and entrepreneurs, allowing them to thrive in a digital economy, while the enhanced experience brought about by the digitalisation will provide a sustainable and connected environment for the community. The first buildings in District are expected to be completed by 2023. --------------------------------------------------------------------------------------------------------------------------- 2 About JTC Set up in 1968, JTC is the lead government agency responsible for the planning and development of industrial infrastructure to support and catalyse the growth of industries and enterprises in Singapore.

Free N95 masks in kits for every home BY ADRIAN LIM E VERY household here will receive three N95 face masks, as part of a nation-wide push to get individuals to think about being prepared for emergencies, such as haze crises and flu pandemics. The 3M brand foldable masks are packed in a “Stay Prepared” kit that will also contain instructions in four languages on how to put them on, and useful emergency contact numbers. A total of 1.2 million kits will be delivered to homes between today and next Monday. The initiative is led by Temasek Cares, a non-profit philantrophic arm under Temasek Holdings, in partnership with Singapore Power and Singapore Post. Temasek Cares will be pumping in $4 million from its $40 million war chest, called the Temasek Emergency Preparedness Fund, for the mask distribution programme. The fund was set up earlier this year to help Singaporeans prepare and deal with emergencies. Last month, a $1.5 million project to train 60 therapists to help children deal with traumatic situations, such as accidents, was also launched. Richard Magnus, chairman of Temasek Cares, said the kits will give households an “initial stock” of masks to encourage them to plan their own contingencies. “It’s a habit of mind we want to prompt... Last June, there was a severe haze that impacted Singapore... we need to be prepared,” said Mr Magnus. The Asean Specialised Meteorological Centre expects this year’s haze to be worse than last year’s. This is because of lower than usual rainfall expected from now till October in parts of the region and the El Nino weather pattern, which is linked to drought, said reports. Being prepared earlier will also prevent a repeat of last June, when people scrambled to stock up on face masks. An additional 17,000 kits will also be delivered to over 140 charity homes, and another 300,000 have been prepared on standby for needy families. Mary Abishagam, 57, a senior administrative assistant with Singapore Power, said she will be volunteering an extra three hours every day, on top of her regular work, to help pack the kits for delivery. “It’s going to be challenging, but we will manage... We are getting people prepared and not many people have thought of keeping masks in their homes,” she said cheerily. Members of the public who wish to get more information about the delivery of the kits can call a hotline, 1800-738-2000, from today until May 24, between 8am and 8pm daily. adrianl@sph.com.sg

MEDIA RELEASE SP Group recognised with three Community Chest Awards SP scaled up giving, expanded programmes to benefit seniors, children and youth SP Group CEO Mr Stanley Huang received the Charity Platinum Award from President Halimah Yacob. Singapore, 1 November 2022 – At the Community Chest Awards 2022, SP Group (SP) was recognised with three awards for its sustained philanthropy, strong volunteerism culture and community engagement. Group Chief Executive Officer Stanley Huang received SP’s Charity Platinum Award, Enabler Award, and Volunteer Partner Award at the event presided by President Halimah Yacob on 1 November 2022 at the Istana. Working closely with Community Chest has enabled SP to effectively identify needs, collaborate with social service agencies and create sustained impact to help vulnerable groups. Mr Huang said, “SP is honoured to receive this recognition from Community Chest. Despite the challenges brought on by the pandemic, we scaled up our efforts to fulfil long-standing commitments and set up new programmes to benefit a wider range of social service users, from seniors, to children and youth.” Mr Huang paid tribute to SP’s staff, business associates and the public for enabling its programmes to grow from strength to strength over the years. Last year, SP’s contributions totalled S$4.5 million in donations, sponsorships and volunteer manpower. These include maintaining support for 21,000 seniors through the SP Heartware Fund, which has raised more than S$18 million since it was established in 2005. In addition, SP also committed S$1.1 million this year to see through a five-fold increase in its annual Power Packs initiative, enabling 10,000 lower-income families to receive daily essential items. In widening the scope of its programmes across the age spectrum, SP launched SP Kids at Heart, donating S$2.1 million over the past two years to support 5,000 children under KidSTART with learning tools, including digital devices for home-based learning and early literacy development. 1 SP also extended its reach to youth from vulnerable backgrounds by launching the inaugural SP Group Engineering Study Awards this year with a contribution of S$1.35 million to the Institute of Technical Education (ITE). This will benefit 450 ITE students from lower-income families over the next three years. Through this study award, SP aims to aid aspiring engineers in securing better academic and employment opportunities. In amplifying fundraising efforts for the SP Heartware Fund, SP enables its customers and business associates to donate to Community Chest through the SP app and donation appeals in its utilities bills. SP also matches dollar-for-dollar donations made by its staff to the Fund, and underwrites all fund-raising and operational costs of the Fund and its programmes, so that all donations will go fully to the social service organisations. Staff volunteers, known as SP Heart Workers, organise outreach activities for social service users throughout the year. These include befriending activities at Senior Activity Centres, helping seniors with their grocery runs, conducting digital clinics and more. At the height of the pandemic, SP Heart Workers also partnered FairPrice to bring a mobile supermarket to the doorstep of seniors. SP’s staff have also been part of national-level efforts to provide pandemic relief to the public, including the manning of hotlines for Temasek Foundation’s Stay Prepared programme and Ministry of Health’s home recovery scheme. Mr Huang explained, “Over the years, we have developed a strong culture of volunteerism amongst our team members. This shared purpose of pursuing a common good unifies our people, fosters team-building and cultivates the spirit of giving.” SP Group has received the Charity Platinum Award and Volunteer Partner awards in past editions of the Community Chest Awards, held annually to honour organisations and individuals in Singapore who have made outstanding contributions to the social service sector to care for the less fortunate in the community. - Ends - About SP Group SP Group is a leading utilities group in the Asia Pacific, empowering the future of energy with low-carbon, smart energy solutions for its customers.

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.

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. In addition to that, consumers would need to register their load and generation accounts under the same entity with SPS. The required registration documents can be found 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.

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.
