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.

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.

Sembcorp, SP to create platform with renewable energy certificate marketplace By Rachel Mui rachmui@sph.com.sg @RachelMuiBT Singapore ENERGY companies Sembcorp Industries and SP Group are collaborating to develop an environmental sustainability platform for corporates and consumers, with a marketplace that trades renewable energy certificates (RECs) and carbon credits, as well as to provide carbon consulting services. The launch of the platform is planned for the first quarter of next year, both firms said in a joint statement on Tuesday. RECs are a recognised way of achieving green targets and a means for buyers to report that their consumed energy comes from renewable energy sources. Carbon credits are tradeable certificates that allow buyers to offset their greenhouse gas emissions (GHG) by supporting projects aimed at reducing GHG emissions. Meanwhile, carbon consulting services include analysis, advisory and strategy development to assist corporates in achieving their carbon emission reduction targets, Sembcorp and SP Group said. They added that companies are increasingly incorporating environmental, social and corporate governance factors into their business strategies and practices, which has led to a growing demand for environmental solutions to offset GHG emissions. The platform will tap the expertise of both parties to provide consultancy services that encompass physical and digital solutions across energy, water and waste management, enabling corporates to achieve their GHG reduction targets, the firms noted. In 2015, Singapore pledged to reduce the nation’s emission intensity by 36 per cent from 2005 levels by 2030, and to stabilise emissions with the aim of peaking around 2030. The national target is to halve emissions from its peak to 33 million tonnes of carbon dioxide equivalent by 2050, with a view to achieving net zero emissions as soon as viable in the second half of the century. Sembcorp shares closed six cents or 4 per cent higher at S$1.54 on Tuesday.

SP Energy HubAnnual ReportReliabilitySustainabilityInnovation World’s First Index for Smart Grid INNOVATION SP Group launched the world's first smart grid index to help utilities measure and advance in key dimensions of grid development. Using publicly available data, SP applied the framework on 45 utilities across 30 countries. The published results allow utilities to identify best practices by leading players. This supports industry development in using smart grids to enhance service and save cost. The Smart Grid Index (SGI) was welcomed and met with strong endorsement from industry experts and stakeholders when previewed at renowned industry platforms such as the International Utility Working Group and the  Conference of the Electric Power Supply Industry (CEPSI). The index’s methodology was also validated by the Energy Research Institute @ NTU (ERI@N). The SGI was designed to be simple and quantifiable for utilities to easily determine what aspects they are strong in and where they can improve.  It covers seven key aspects of an electricity grid: supply reliability; monitoring and control; data analytics; integration of Distributed Energy Resources (DER); green energy; security; and customer empowerment and satisfaction.
