10月17日，中國電(dian)(dian)建所屬水電(dian)(dian)八局承建的(de)我國東(dong)北最(zui)大抽(chou)水蓄能電(dian)(dian)站(zhan)——遼(liao)寧清原(yuan)抽(chou)水蓄能電(dian)(dian)站(zhan)下(xia)水庫大壩提前封(feng)頂(ding)，為電(dian)(dian)站(zhan)后續完工發電(dian)(dian)奠(dian)定了堅(jian)實基礎。

下水庫(ku)大(da)壩(ba)(ba)(ba)(ba)為混凝土(tu)面(mian)板堆(dui)石壩(ba)(ba)(ba)(ba)，1級建筑物，正常蓄水位319米(mi)(mi)，壩(ba)(ba)(ba)(ba)頂長375米(mi)(mi)，最大(da)壩(ba)(ba)(ba)(ba)高49米(mi)(mi)，于(yu)5月截流、10月實現封頂，歷(li)時5個月完成(cheng)施工任務。自(zi)大(da)壩(ba)(ba)(ba)(ba)填(tian)(tian)筑以來(lai)，清原(yuan)項目(mu)部克(ke)服臺風等多方不利因素影(ying)響，科(ke)學組(zu)織，精心施工，并通過(guo)成(cheng)立“大(da)壩(ba)(ba)(ba)(ba)填(tian)(tian)筑黨員先鋒(feng)崗”“下水庫(ku)大(da)壩(ba)(ba)(ba)(ba)填(tian)(tian)筑專項小(xiao)組(zu)”以及“大(da)壩(ba)(ba)(ba)(ba)填(tian)(tian)筑青年突擊隊”，充分發揮先鋒(feng)模范作用，在保證安全施工的(de)(de)同時，提前達到下水庫(ku)大(da)壩(ba)(ba)(ba)(ba)填(tian)(tian)筑完成(cheng)的(de)(de)重要(yao)節點。

據(ju)了解，清原抽水(shui)蓄(xu)能(neng)電(dian)(dian)(dian)(dian)站(zhan)位(wei)于遼(liao)(liao)寧省撫順市(shi)清原滿族(zu)自治縣北(bei)(bei)三家鎮(zhen)境內，是國家振興(xing)東北(bei)(bei)經(jing)濟139個項(xiang)目(mu)排名第一(yi)的(de)工程，總裝(zhuang)(zhuang)機容量180萬千(qian)瓦(wa)，設計年發電(dian)(dian)(dian)(dian)量30億千(qian)瓦(wa)時，抽水(shui)電(dian)(dian)(dian)(dian)量40億千(qian)瓦(wa)時，為東北(bei)(bei)地區最大(da)的(de)抽水(shui)蓄(xu)能(neng)電(dian)(dian)(dian)(dian)站(zhan)，也(ye)是目(mu)前全(quan)國在建水(shui)電(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)機容量前三的(de)工程。項(xiang)目(mu)建成后，將(jiang)作為重(zhong)要(yao)(yao)“調節(jie)器”“穩(wen)壓器”和“電(dian)(dian)(dian)(dian)力(li)糧倉”，在遼(liao)(liao)寧電(dian)(dian)(dian)(dian)網(wang)(wang)中承擔調峰(feng)、填谷、調頻(pin)、調相、負荷(he)備用(yong)(yong)和緊急事故備用(yong)(yong)等任(ren)務，對保證遼(liao)(liao)寧電(dian)(dian)(dian)(dian)網(wang)(wang)和東北(bei)(bei)電(dian)(dian)(dian)(dian)網(wang)(wang)安全(quan)穩(wen)定運行(xing)，有效吸納(na)風電(dian)(dian)(dian)(dian)、光伏發電(dian)(dian)(dian)(dian)、核電(dian)(dian)(dian)(dian)等新能(neng)源(yuan)，進一(yi)步優化東北(bei)(bei)電(dian)(dian)(dian)(dian)網(wang)(wang)電(dian)(dian)(dian)(dian)源(yuan)結(jie)構起到重(zhong)要(yao)(yao)作用(yong)(yong)。
