“儿子耕了母亲荒废的田”浙江柯城抽水蓄儿子耕了母亲荒废的田能电站工程开建 将提升华东电网调度灵活性

  中新儿子耕了母亲荒废的田网衢州12月26日电(儿子耕了母亲荒废的田鲍梦妮 张斌 张悦)据国网浙江省电力有限公司12月26日消息,当日,国家《抽水蓄能中长期发展规划(2021-2035)》“十四五”重点实施项目、浙江省“千项万亿”工程——浙江柯城抽水蓄能电站工程启动建设。

  该项目总投资约79.37亿元,装机容量120万千瓦,建成后主要承担电网的调峰、填谷、储能、调频、调相和紧急事故备用等任务。

  这一大型“储能巨擘”位于浙江省衢州市柯城区七里乡大山深处,充分利用地形地势差,建设上下两个水库。其中上水库坝高132.5米,为目前浙江省抽蓄电站第一高坝。电站在电力富余时把低处的水用低谷电能抽到高处储能,在用电高峰时把高处的水放下发电保供,实现“削峰填谷”,助力大电网平稳运行,提升华东电网调度灵活性。

  该工程设计年发电量12亿千瓦时,年抽水电量16亿千瓦时,预计在2031年实现全部机组投产。投产后,预计每年可节约系统耗煤量约23.3万吨,减少碳排放约46.6万吨,也将成为国内首个实现土石方库内自平衡的节地环保抽水蓄能电站。

  据悉,浙江柯城抽水蓄能电站是浙江“十四五”期间开工建设的第17座抽水蓄能电站,目前浙江抽水蓄能项目投产建设总规模位于全国第一。

  如此规模抽水蓄能电站因何建设?2024年,浙江迎来清洁能源占比超五成的历史性节点,风光、核电等清洁能源比重逐年提高,消纳区外特高压直流来电持续增加。为解决风电、光伏发电等新能源的间歇性、波动性问题,电力系统对调节电源的需求愈加迫切。

  “在诸多调节电源和储能方式中,抽水蓄能电站因其运行灵活、技术成熟、绿色环保及可为电力系统提供转动惯量等优势,是目前最具规模化发展条件的灵活性资源。”浙江柯城抽水蓄能有限公司董事长叶炯介绍,电网可利用抽水蓄能电站“调峰”“填谷”双倍容量功能,助力风光等可再生能源的消纳,保障电力系统的安全稳定经济运行。(完)
