 煤电“三改联动”是我国煤电行业践行“双碳”战略的重要举措,也是促进传统火力发电向新型智慧火力发电转型升级的有效途径。煤电行业既要发挥兜底保障作用,又要不断提升清洁高效发展水平,“三改联动”是关键一步。

  煤电灵活性改造持续推进

  我国以煤为主的基本国情,决定了煤电在相当长时期内仍将承担保障能源电力安全的重要作用。目前,煤电以占比不到五成的装机,生产了约六成的电量,支撑了超七成的高峰负荷需求。

  煤电行业是我国电力领域中二氧化碳排放的重点行业。近年来,国家频繁对相关工作进行部署。2021年10月,国家发展改革委、国家能源局联合印发《全国煤电机组改造升级实施方案》,进一步明确存量煤电机组灵活性改造应改尽改,“十四五”期间完成改造2亿千瓦,增加系统调节能力3000万~4000万千瓦,促进清洁能源消纳。2022年3月,《“十四五”现代能源体系规划》出台,就“能源系统效率大幅提高”提出“到2025年,灵活调节电源占比达到24%左右”。

  与此同时,多地也将煤电灵活性改造纳入重点工作,并制定了实施计划表。

  2021年6月,《内蒙古自治区煤电节能降耗及灵活性改造行动计划(2021~2023年)》发布,提出到2023年,力争燃煤发电机组完成灵活性改造2000万千瓦,增加系统调节能力400万~500万千瓦。

  2022年5月,《重庆市应对气候变化“十四五”规划(2021~2025年)》发布,提出加快推动30万千瓦级和部分60万千瓦级燃煤机组灵活性改造。同月,《天津市“十四五”节能减排工作实施方案》发布,要求有序推动自备燃煤机组改燃关停,推进现役煤电机组节能升级和灵活性改造。
