目前，我国通用的碳排放核算方法是将企业"用电量"乘以"电碳因子"，从而得到企业用电产生的碳排放量。电碳因子全年采用测算的固定值，无法体现不 同时段、不同区域碳排放的差异。"这就像是用全年平均气温指导每天穿衣，计算出的碳排放量往往高于实际碳排放量，加重了出口产品的成本负担。"国 网常州供电公司碳资产管理办公室主任赵清源表示。 为了给国际绿色贸易提供真实可靠、互通互认的碳排数据，国网江苏电力在国家电网公司碳业务体系的指导下率先探索攻坚，提出了分时、分区、分压电 碳因子模型和计算方法，率先部署在省级碳资产管理平台。国网常州供电公司紧随其后，研制出能与碳资产管理平台双向通信的新型碳计量装置，动态监 测企业用电情况，实时接收平台发布的电碳因子，实现电力碳排放高精度核算。 在此基础上，国网常州供电公司还配套开发了企业端碳排放监控系统，不仅可以在前端装置界面上读取实时电碳因子、实时碳排放量等信息，还可以通过 监控系统了解设备、厂区等不同维度下的历史碳排放量与用电数据，助力企业制定更加科学合理的节能降耗举措。 9月1日，江苏省首台搭载分时分区分压电碳因子的碳计量装置在常州金坛金能电力有限公司正式投运，能够实现企业碳排放精准计 ...
