Media Release Electricity Tariff Revision for the Period 1 July to 30 September 2022 Singapore, 30 June 2022 – For the period from 1 July to 30 September 2022, electricity tariff (before 7% GST) will increase by an average of 8.1% or 2.21 cents per kWh compared with the previous quarter. The increase is mainly due to higher energy cost driven by rising 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 27.94 to 30.17 cents per kWh for 1 July to 30 September 2022. The average monthly electricity bill for families living in HDB four-room flats will increase by $8.25 (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. Appendix 1 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: 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. Network costs (paid to SP Group): This is to recover the cost of transporting electricity through the power grid. 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. 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.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Growing Greener and Cooler Outdoors SUSTAINABILITY Photo: NDP 2018 Exco Powering Singapore’s birthday celebrations comes with a greener and cooler upgrade. Back for a second year, SP Group and ST Engineering have an improved outdoor cooling solution at the National Day Parade 2018, to help spectators beat the heat. The system will cool sections seating beneficiaries with special needs, such as those in wheelchairs. These spectators can enjoy the parade, performances and festivities in cool comfort outdoors, through this made-in-Singapore innovation. This year’s improved version has direct individualised air outlets with adjustable louvers that uniformly distributes cold air as low as 22 degrees celsius throughout the area. It has also been designed to blend into the seating area to optimise space and avoid obstructing spectators’ view. "It's a brilliant idea that is cooling everyone. It's helping all the spectators here, making them so comfortable. I was here last year and this makes it a world of difference." — Suresh Vanaz "This is my first NDP, and when I arrived, I was surprised to find this cooling solution at my seat. It certainly makes it a more comfortable and enjoyable experience." — Theresa Lee Building on SP’s underground district cooling network at Marina Bay, this solution also consumes 90 per cent less energy than conventional air-conditioning for the same cooling capacity. — 6 August 2018 TAGS SUSTAINABILITYOUTDOOR COOLINGDISTRICT COOLING YOU MIGHT BE INTERESTED TO READ SP Group expands sustainable energy operations in China with Chongqing Transport Hub project win STMicroelectronics enhances sustainability with chiller cooling system at Toa Payoh SP signs PPA with BASF for rooftop solar deployment

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.

Joint News Release SP GROUP PARTNERS SINO-SINGAPORE GUANGZHOU KNOWLEDGE CITY TO DEVELOP ENERGY-SAVING SOLUTIONS Singapore & China, 31 August 2020 – SP Group (SP) today signed an agreement with the Sino- Singapore Guangzhou Knowledge City Investment and Development Co. Ltd (GKC Co) to establish a joint venture (SP-GKC JV Co) to develop district cooling, heating and integrated energy solutions that will help the China-Singapore Guangzhou Knowledge City (CSGKC) to achieve energy savings. The joint venture agreement was signed by SP’s Group Chief Executive Officer Mr Stanley Huang and GKC Co’s Chief Executive Officer Mr Chen Changxin at the 11th Singapore-Guangdong Collaboration Council (SGCC) meeting. The meeting, held over video conference in Guangzhou and Singapore, was co-chaired by Guangdong Governor Mr Ma Xingrui and Singapore’s Transport Minister Mr Ong Ye Kung. As part of the agreement, SP and GKC Co are working together to develop district cooling and heating solutions for the Knowledge Tower at the Jiulong Lake area in GKC. Leveraging the technology and SP’s experience in the energy industry, both parties will also focus on integrating sustainable energy solutions such as distributed energy, energy storage, energy efficiency and energy management systems. In the next phase of development, these solutions could be extended to other projects in the Sino- Singapore International Technology Innovation Cooperation Demonstration Area within CSGKC, to enable more customers to enjoy substantial energy and cost savings. This will translate to a cleaner and more sustainable energy future for CSGKC and Guangzhou city. Mr Stanley Huang, Group Chief Executive Officer of SP Group said: “Our technology and operations at Raffles City Chongqing and Singapore’s Marina Bay have helped customers achieve cost savings and reduce energy consumption by 40 per cent. Through this partnership with CSGKC, SP Group looks forward to supporting China’s goal to build an ecological civilisation and Beautiful China 1 , with our smart and sustainable energy solutions. Together, we aim to enable customers in China to enjoy a sustainable, low-carbon future.” 1 The Beautiful China initiative is a plan for the sustainable development of the Chinese nation as well as for China to fulfill the United Nations’ 2030 Agenda for Sustainable Development. 1 Mr. Chen Changxin, CEO of GKC Co said: "As an important platform for China-Singapore collaboration, GKC Co has started the exchanges and cooperation with SP Group since the ground-breaking of GKC. This year marks the 30th anniversary of China-Singapore diplomacy and the 10th anniversary of GKC, it is a milestone for us to jointly establish a joint venture to develop the smart energy business. Based on the principle of “government-supported, enterprise-led, market-driven” and with the Knowledge Tower project at the Jiulong Lake as a start, we will implement investment, construction and operation of district cooling and heating solutions centred on the smart micro-grids layout, promote the development of smart energy businesses in GKC and gradually extend to GBA, so as to achieve synergistic improvement of commercial value, corporate benefits and social effects, and jointly create another successful model of China- Singapore collaboration." Raffles City Chongqing, where SP Group operates its advanced energy-efficient cooling and heating system, commenced operations in September 2019. SP’s cooling operations enabled Raffles City Chongqing to reduce energy consumption by more than 40 per cent savings, compared to conventional building chiller plants. SP designed and operates the world’s largest underground district cooling system at Singapore’s Marina Bay Financial district. Besides achieving substantial energy efficiency, the Marina Bay district cooling network achieved 100% reliability for 13 consecutive years, since it commenced operations in 2006. -Ends- 2 新 闻 稿 新 加 坡 能 源 集 团 携 手 中 新 广 州 知 识 城 实 现 节 能 解 决 方 案 ( 新 加 坡 、 中 国 ,2020 年 8 月 31 日 ) 新 加 坡 能 源 集 团 (SP Group) 今 天 宣 布 与 中 新 广 州 知 识 城 投 资 开 发 有 限 公 司 ( 简 称 “ 知 识 城 合 资 公 司 ”) 签 署 合 作 协 议 , 双 方 成 立 合 资 企 业 开 发 区 域 供 冷 供 热 及 综 合 能 源 解 决 方 案 , 帮 助 中 新 广 州 知 识 城 ( 简 称 “ 知 识 城 ”) 实 现 节 能 减 排 目 标 。 新 加 坡 能 源 集 团 总 裁 黄 天 源 和 知 识 城 合 资 公 司 总 裁 陈 长 新 在 新 加 坡 - 广 东 合 作 理 事 会 ( 简 称 “ 新 粤 合 作 理 事 会 ”) 第 十 一 次 会 议 上 签 署 了 该 合 资 协 议 。 广 东 省 省 长 马 兴 瑞 先 生 和 新 加 坡 交 通 部 长 王 乙 康 先 生 分 别 在 广 州 和 新 加 坡 主 持 了 此 次 线 上 视 频 会 议 。 按 照 协 议 , 新 加 坡 能 源 集 团 与 知 识 城 合 资 公 司 将 共 同 开 发 知 识 城 九 龙 湖 “ 知 识 塔 ” 片 区 的 区 域 供 冷 供 热 解 决 方 案 。 同 时 , 借 助 新 能 源 集 团 在 能 源 领 域 的 经 验 和 技 术 , 双 方 还 将 关 注 一 体 化 能 源 解 决 方 案 , 如 分 布 式 能 源 、 储 能 、 能 效 管 理 及 整 合 能 源 管 理 系 统 等 方 面 。 下 一 阶 段 , 这 些 技 术 将 拓 展 到 广 州 知 识 城 “ 中 新 国 际 科 技 创 新 合 作 示 范 区 ” 的 其 他 项 目 中 , 使 更 多 客 户 受 益 于 能 耗 和 成 本 的 大 幅 下 降 。 这 也 将 为 知 识 城 和 广 州 市 更 清 洁 、 可 持 续 的 能 源 事 业 发 展 助 力 。 新 加 坡 能 源 集 团 总 裁 黄 天 源 先 生 说 :“ 我 们 创 新 的 技 术 和 营 运 为 重 庆 来 福 士 和 新 加 坡 滨 海 湾 的 客 户 节 约 了 百 分 之 四 十 的 能 耗 。 新 加 坡 能 源 集 团 希 望 能 够 通 过 这 次 中 新 广 州 知 识 城 的 合 作 , 用 我 们 的 智 慧 可 持 续 能 源 解 决 方 案 , 继 续 支 持 中 国 的 生 态 文 明 和 ‘ 美 丽 中 国 ’ 2 建 设 , 实 现 低 碳 和 可 持 续 发 展 的 未 来 。” 知 识 城 合 资 公 司 总 裁 陈 长 新 说 :“ 这 个 合 资 企 业 的 建 立 正 值 中 新 建 交 30 周 年 和 广 州 知 识 城 成 立 10 周 年 , 对 于 知 识 城 智 慧 能 源 产 业 发 展 来 说 有 着 里 程 碑 式 的 意 义 。 我 们 将 坚 持 ‘ 政 府 引 导 、 企 业 先 行 、 市 场 化 运 作 ’ 的 原 则 , 以 九 龙 湖 知 识 塔 项 目 为 起 点 , 围 绕 智 能 微 2 ‘ 美 丽 中 国 ’ 建 设 是 中 国 实 现 联 合 国 2030 年 可 持 续 发 展 议 程 的 计 划 。 3 网 布 局 实 施 区 域 制 冷 和 供 热 解 决 方 案 的 投 资 、 建 设 和 运 营 。” 陈 长 新 表 示 , 双 方 还 将 持 续 提 升 知 识 城 智 慧 能 源 产 业 发 展 水 平 , 并 将 成 功 经 验 推 广 至 粤 港 澳 大 湾 区 , 从 而 实 现 商 业 价 值 、 企 业 效 益 和 社 会 效 应 的 协 同 提 高 , 共 同 打 造 中 新 合 作 的 又 一 成 功 典 范 。 新 加 坡 能 源 集 团 在 新 加 坡 滨 海 湾 金 融 区 设 计 打 造 了 世 界 上 最 大 的 地 下 区 域 供 冷 系 统 。 该 系 统 自 2006 年 投 入 运 营 以 来 已 连 续 十 三 年 实 现 100% 的 可 靠 性 。2019 年 9 月 正 式 营 业 的 重 庆 来 福 士 广 场 也 采 用 了 新 能 源 集 团 的 尖 端 高 效 节 能 供 冷 供 热 系 统 , 实 现 了 高 达 40% 以 上 的 节 能 效 果 。 新 加 坡 能 源 集 团 将 以 中 新 广 州 知 识 城 合 作 项 目 为 契 机 , 为 中 国 持 续 带 来 高 效 节 能 的 解 决 方 案 , 助 力 “ 美 丽 中 国 ” 建 设 。 - 完 - 4 Notes to Editor About the Marina Bay District Cooling Network Artist Impression of Knowledge Tower 5 About SP Group SP Group is a leading energy utilities group in the Asia Pacific.
