抽水蓄能是指在用电低谷时,利用风电、光电等清洁能源将水抽到山上,在用电高峰时再放水发电。这个转化过程也就解决了一直以来电能难以储存的难题,因此,抽水蓄能电站也可以称得上是超级“充电宝”。当前,我国的单个抽水蓄能电站装机容量以及全国装机总量均位居全球首位。
河北丰宁抽水蓄能电站是全球最大装机的抽水蓄能电站,总装机容量360万千瓦,总投资超过了192亿元,共安装12台抽水蓄能发电机组。
丰宁抽水蓄能电站就是在山上、山下分别建设水库,通过电网调度,在用电低谷时利用富余的风电、光伏电能把水抽到山上,在用电高峰时放水发电,不仅把富余的清洁能源存了起来,还是电力系统的稳定器、调节器和平衡器。
在安徽金寨抽水蓄能电站,截至10月26日,累计发电量近1.6亿度。
截至目前,国家电网经营区在建在运抽水蓄能电站70座、装机8524万千瓦,分别是2012年的3.2倍、4.1倍。预计到2030年装机容量将达到1亿千瓦。
