6月3日，酒泉(quan)(quan)(quan)—湖(hu)南(nan)(nan)(nan)±800千(qian)伏特高(gao)壓直流工(gong)(gong)(gong)程(cheng)（以下簡稱“酒泉(quan)(quan)(quan)—湖(hu)南(nan)(nan)(nan)工(gong)(gong)(gong)程(cheng)”）開工(gong)(gong)(gong)動員大會在甘(gan)(gan)(gan)肅酒泉(quan)(quan)(quan)和(he)湖(hu)南(nan)(nan)(nan)湘潭召開。酒泉(quan)(quan)(quan)—湖(hu)南(nan)(nan)(nan)工(gong)(gong)(gong)程(cheng)是甘(gan)(gan)(gan)肅省(sheng)首(shou)個(ge)特高(gao)壓電(dian)網工(gong)(gong)(gong)程(cheng)，也是湖(hu)南(nan)(nan)(nan)省(sheng)首(shou)個(ge)特高(gao)壓電(dian)網工(gong)(gong)(gong)程(cheng)。工(gong)(gong)(gong)程(cheng)建(jian)成(cheng)后，將構建(jian)西電(dian)東(dong)送(song)大動脈(mo)，實現甘(gan)(gan)(gan)肅風電(dian)、煤電(dian)的大規(gui)模開發、打捆外送(song)和(he)大范(fan)圍(wei)優(you)化配置，有效緩解(jie)華(hua)中地區用電(dian)緊張局面(mian)。
酒(jiu)泉—湖(hu)南工(gong)程(cheng)(cheng)途經甘(gan)肅、陜西(xi)、重慶、湖(hu)北、湖(hu)南5省（市），新建(jian)酒(jiu)泉、湘潭2座(zuo)換(huan)流站(zhan)，換(huan)流容(rong)量(liang)1600萬千瓦，線路全長(chang)2383千米，工(gong)程(cheng)(cheng)動(dong)(dong)態投資262億(yi)元，于(yu)2015年(nian)5月(yue)獲得(de)國家發(fa)改委核準(zhun)，計(ji)劃于(yu)2017年(nian)建(jian)成投運。該(gai)工(gong)程(cheng)(cheng)是目前世(shi)界上送電(dian)(dian)(dian)距離最長(chang)的特高壓(ya)輸電(dian)(dian)(dian)工(gong)程(cheng)(cheng)，也是重點服務風電(dian)(dian)(dian)、太陽能(neng)發(fa)電(dian)(dian)(dian)等新能(neng)源送出的跨區(qu)輸電(dian)(dian)(dian)通道。工(gong)程(cheng)(cheng)對實現甘(gan)肅風電(dian)(dian)(dian)、煤電(dian)(dian)(dian)的大(da)規模開發(fa)、打(da)捆外送和大(da)范圍優化配置(zhi)，緩解華中地(di)區(qu)用電(dian)(dian)(dian)緊張狀況，有效減少霧霾、改善(shan)大(da)氣環境(jing)質量(liang)，拉動(dong)(dong)內需和經濟增(zeng)長(chang)，帶(dai)動(dong)(dong)裝備(bei)制造業轉型(xing)升級均具有十分重要的意義。
作為首條直(zhi)接為湖南(nan)供(gong)電(dian)(dian)的特(te)高壓(ya)線路，酒泉(quan)—湖南(nan)工程建成后，每年(nian)可(ke)為湖南(nan)輸送400億千瓦(wa)時電(dian)(dian)量(liang)，將開通(tong)外(wai)電(dian)(dian)入湘的“直(zhi)通(tong)車”，為湖南(nan)能源供(gong)應提供(gong)可(ke)靠保障。經測算(suan)，該線路年(nian)輸送電(dian)(dian)量(liang)相(xiang)當(dang)于6個長沙電(dian)(dian)廠的年(nian)發電(dian)(dian)量(liang)，可(ke)滿足湖南(nan)年(nian)用電(dian)(dian)需求(qiu)的四分之一。將帶(dai)動總投資為700多億元(yuan)的風(feng)電(dian)(dian)、光(guang)伏發電(dian)(dian)及(ji)配套(tao)調峰火電(dian)(dian)等(deng)項(xiang)目建設，必將為新常態(tai)下甘(gan)肅全省和地區(qu)經濟社(she)會發展注入巨大活力(li)，帶(dai)來重(zhong)要機遇。
