8月25日，酒泉(quan)—湖(hu)南±800千伏(fu)特(te)高(gao)壓直流輸電線(xian)(xian)路(lu)工(gong)(gong)程(cheng)（甘肅(su)段(duan)）首基基礎澆(jiao)制試點在甘肅(su)省金昌市永(yong)昌縣(xian)下(xia)四壩(ba)村1719號塔位(wei)順利(li)完成，標志(zhi)著該工(gong)(gong)程(cheng)線(xian)(xian)路(lu)工(gong)(gong)程(cheng)進入全面建設階段(duan)。
酒泉—湖(hu)南(nan)±800千伏特高壓直(zhi)流輸(shu)電線路工(gong)(gong)程(cheng)(cheng)是第一條(tiao)落點甘肅(su)的(de)新能源外送直(zhi)流輸(shu)電通道，也(ye)是甘肅(su)公司承擔的(de)第二條(tiao)特高壓直(zhi)流工(gong)(gong)程(cheng)(cheng)建設任務。工(gong)(gong)程(cheng)(cheng)在甘肅(su)境內(nei)線路途徑酒泉、張掖、金昌、武威、蘭州、白銀、定西、天水、隴南(nan)等9市(shi)22縣(xian)，線路全(quan)(quan)長1247.8千米(mi)，占全(quan)(quan)線總(zong)長的(de)52%，鐵(tie)塔總(zong)計(ji)2394基，動態投資55.66億元，預計(ji)在工(gong)(gong)程(cheng)(cheng)施工(gong)(gong)高峰(feng)期投入施工(gong)(gong)人(ren)員達上萬人(ren)，預計(ji)2016年12月完成施工(gong)(gong)，具備(bei)帶(dai)電條(tiao)件。
該工(gong)程(cheng)建(jian)(jian)設規模(mo)大，線(xian)(xian)(xian)路(lu)(lu)路(lu)(lu)徑長，沿線(xian)(xian)(xian)地形、地質情況復雜(za)，氣(qi)候(hou)條件(jian)惡劣，建(jian)(jian)設環境艱苦；通道(dao)清理任(ren)務重，跨(kua)(kua)越(yue)(yue)眾(zhong)多，共跨(kua)(kua)越(yue)(yue)在建(jian)(jian)高鐵(tie)(tie)(tie)1次(ci)，電(dian)氣(qi)化(hua)鐵(tie)(tie)(tie)路(lu)(lu)4次(ci)，一般鐵(tie)(tie)(tie)路(lu)(lu)4次(ci)，高速公(gong)路(lu)(lu)12次(ci)，±800千(qian)伏電(dian)力(li)線(xian)(xian)(xian)路(lu)(lu)1次(ci)，750千(qian)伏電(dian)力(li)線(xian)(xian)(xian)路(lu)(lu)11次(ci)，330千(qian)伏電(dian)力(li)線(xian)(xian)(xian)路(lu)(lu)23次(ci)，跨(kua)(kua)越(yue)(yue)一般公(gong)路(lu)(lu)、110千(qian)伏及以下電(dian)力(li)線(xian)(xian)(xian)路(lu)(lu)200余次(ci)，安全(quan)風險管(guan)控壓力(li)巨大。
酒泉—湖(hu)(hu)南±800千(qian)伏特(te)高壓直流(liu)(liu)(liu)輸(shu)電(dian)線(xian)路(lu)(lu)工(gong)(gong)程(cheng)(cheng)是(shi)(shi)我國(guo)第一條大規模(mo)輸(shu)送(song)清(qing)潔電(dian)力特(te)高壓直流(liu)(liu)(liu)工(gong)(gong)程(cheng)(cheng)，也是(shi)(shi)目前國(guo)內直流(liu)(liu)(liu)輸(shu)電(dian)線(xian)路(lu)(lu)最長的電(dian)力工(gong)(gong)程(cheng)(cheng)。該工(gong)(gong)程(cheng)(cheng)起點(dian)為甘(gan)肅(su)酒泉橋灣(wan)換流(liu)(liu)(liu)站，終點(dian)為湖(hu)(hu)南湘潭換流(liu)(liu)(liu)站，工(gong)(gong)程(cheng)(cheng)線(xian)路(lu)(lu)途經甘(gan)肅(su)、陜西(xi)、重慶、湖(hu)(hu)北(bei)、湖(hu)(hu)南4省(sheng)1直轄市，路(lu)(lu)徑全長約2381.93千(qian)米。工(gong)(gong)程(cheng)(cheng)建成后，預計年外送(song)電(dian)量(liang)400億千(qian)瓦(wa)時，屆時或將徹底解(jie)決甘(gan)肅(su)省(sheng)河西(xi)地(di)區新能源外送(song)瓶頸。
各參建單(dan)位表示，在工(gong)(gong)程(cheng)(cheng)建設過程(cheng)(cheng)中一定要以高起點、高質(zhi)量、高水平(ping)推(tui)進工(gong)(gong)程(cheng)(cheng)建設，把(ba)酒湖(hu)工(gong)(gong)程(cheng)(cheng)（甘肅段）建設成(cheng)為“安全可靠、自主創新(xin)、經濟合理、環境友好、國(guo)際一流(liu)”的優質(zhi)精(jing)品(pin)工(gong)(gong)程(cheng)(cheng)。
