From June 10th to 12th, the 2026 Shanghai International Carbon Neutrality Technology, Products and Achievements Expo (hereinafter referred to as the "Shanghai International Carbon Neutrality Expo") will be held at the Shanghai New International Expo Center. At the meeting, the Southern Power Grid Energy Institute and the China Energy Research Association Electric Carbon Coupling Technology Special Committee (hereinafter referred to as the "Special Committee") jointly released the Southern Power Grid Provincial Power System Carbon Emission Traceability Database.
6月10日至12日，2026上海国际碳中和技术、产品与成果博览会（以下简称“上海国际碳中和博览会”）在上海新国际博览中心举办。会上，南网能源院与中国能源研究会电碳耦合技术专委会（以下简称“专委会”）联合发布南方电网省域电力系统碳排放可溯源数据库。

This database has functions such as dynamic accounting of carbon emissions in the power system by time and zone, tracing of electricity carbon paths, support for product carbon footprints, and confirmation of multi-party responsibilities. It can provide data support for "dual carbon" assessment, green electricity green certificate consumption certification, and product carbon footprint accounting, marking an important step forward for Southern Power Grid Company's technological influence in the field of electricity carbon coupling.
该数据库具备电力系统碳排放分时分区动态核算、电碳路径追溯、产品碳足迹支撑及多主体责任确认等功能，可为“双碳”考核、绿电绿证消费认证及产品碳足迹核算提供数据支撑，标志着南方电网公司在电碳耦合领域的技术影响力迈出重要一步。

It is reported that this database is an important achievement jointly developed by China Southern Power Grid Energy Research Institute, Guangxi Power Grid Corporation and other units. It has achieved full chain carbon emission tracking from the power generation side to the power consumption side, providing key data support for accurate carbon emission accounting, carbon responsibility identification, green electricity and green certificate accounting, and product carbon footprint evaluation. At present, the database covers four voltage levels ranging from 500 kV to 35 kV in Guangxi, with approximately 3000 main grid power plant nodes, covering various types of power sources such as thermal power, hydropower, nuclear power, wind power, and photovoltaics. It can achieve dynamic carbon factor updates at the 15 minute level and at the city level, with full process verification, evaluation, and traceability capabilities, realizing the full chain tracking of carbon emissions from "source network load". According to database optimization calculations, the carbon footprint of a company's hot-rolled steel coil products has decreased from 2.58 tons of carbon dioxide equivalent to 2.12 tons of carbon dioxide equivalent, a decrease of 17.8%. This can reduce costs by approximately 106 yuan/ton, significantly enhancing the green trade compliance and market competitiveness of export enterprises, fully reflecting the economic transformation potential of the database. Next, Southern Power Grid Energy Institute and the Special Committee will continue to promote the application of this database in the field of electric carbon coupling, and invite more relevant units to join the Special Committee to jointly build an open and collaborative electric carbon ecosystem, serving the national "dual carbon" goal.
据悉，该数据库是南网能源院联合广西电网公司等单位共同攻关的重要成果，实现了从发电侧到用电侧的全链条碳排放追踪，为碳排放精准核算、碳责任认定、绿电绿证核算以及产品碳足迹评价提供关键数据支撑。目前，该数据库已覆盖广西全域500千伏至35千伏共四个电压等级、约3000个主网厂站节点，涵盖火电、水电、核电、风电、光伏等各类电源，可实现15分钟级、地市级的动态碳因子更新，具备全流程校核、评价与溯源能力，实现“源—网—荷”全链条追踪碳排放。经数据库优化测算，某公司热轧钢卷的产品碳足迹从2.58吨二氧化碳当量下降至2.12吨二氧化碳当量，降幅达17.8%，可降低成本约106元/吨，显著提升出口企业绿色贸易合规能力和市场竞争力，充分体现了数据库的经济转化潜力。下一步，南网能源院与专委会将持续推动该数据库在电碳耦合领域的推广应用，并邀请更多相关单位加入专委会，共建开放协同的电碳生态圈，服务国家“双碳”目标。
