2016年(nian)11月11日，國(guo)家清(qing)潔能(neng)源重(zhong)大工(gong)程、我國(guo)第一個采用設(she)計施工(gong)總承包模式進(jin)行建設(she)的(de)百萬千瓦(wa)級(ji)大型(xing)水電(dian)站項目，位(wei)于(yu)涼山(shan)州木(mu)里(li)縣(xian)境內的(de)雅礱江楊房(fang)溝水電(dian)站成功實現大江截流，標志著(zhu)國(guo)家開發投資公司投資建設(she)的(de)該水電(dian)站全(quan)面進(jin)入主體工(gong)程施工(gong)階段。

楊房溝水(shui)電(dian)(dian)站(zhan)(zhan)為雅礱(long)江干流中游“一庫(ku)七級(ji)”開發(fa)的第(di)六(liu)級(ji)水(shui)電(dian)(dian)站(zhan)(zhan)，是(shi)雅礱(long)江流域(yu)水(shui)電(dian)(dian)開發(fa)“四(si)階段”戰略第(di)三階段繼(ji)兩河口(kou)水(shui)電(dian)(dian)站(zhan)(zhan)之后的又一關(guan)鍵工程(cheng)。電(dian)(dian)站(zhan)(zhan)裝(zhuang)機容量150萬(wan)千(qian)瓦(wa)，多年平均發(fa)電(dian)(dian)量68.6 億千(qian)瓦(wa)時。工程(cheng)樞(shu)紐主要由(you)最大壩高(gao)155米的混凝土雙曲(qu)拱壩、泄洪消能建筑物和(he)引(yin)水(shui)發(fa)電(dian)(dian)系(xi)統等組(zu)成(cheng)，電(dian)(dian)站(zhan)(zhan)總(zong)投(tou)資(zi)達200億元，楊房溝水(shui)電(dian)(dian)站(zhan)(zhan)計劃2021年投(tou)產發(fa)電(dian)(dian)，2024年工程(cheng)竣工。

自上世紀末至今，我(wo)國大型水(shui)電(dian)(dian)(dian)站(zhan)(zhan)建(jian)設(she)(she)主要采取(qu)傳統的(de)單價合同模式(shi)(shi)管理(li)(li)，其(qi)特點是將電(dian)(dian)(dian)站(zhan)(zhan)按部位、功能(neng)分(fen)割(ge)為(wei)若(ruo)干合同單元，按建(jian)設(she)(she)程序逐步(bu)招標建(jian)設(she)(she)。在當前經濟結構轉(zhuan)型升(sheng)級(ji)和國家(jia)新(xin)一(yi)輪電(dian)(dian)(dian)力體(ti)制(zhi)改革的(de)大背景下，針對雅礱江(jiang)中上游水(shui)電(dian)(dian)(dian)站(zhan)(zhan)開(kai)發(fa)(fa)環(huan)境(jing)復雜(za)、建(jian)設(she)(she)成本相對較高的(de)特點，為(wei)了控(kong)制(zhi)建(jian)設(she)(she)成本、提升(sheng)管理(li)(li)效(xiao)率，同時也為(wei)我(wo)國水(shui)電(dian)(dian)(dian)行(xing)業(ye)(ye)保(bao)持健康可持續發(fa)(fa)展開(kai)拓出(chu)一(yi)條新(xin)路，雅礱江(jiang)水(shui)電(dian)(dian)(dian)在楊(yang)房(fang)(fang)溝水(shui)電(dian)(dian)(dian)站(zhan)(zhan)選擇了設(she)(she)計施(shi)工(gong)(gong)(gong)總(zong)承(cheng)包(bao)的(de)建(jian)設(she)(she)管理(li)(li)模式(shi)(shi)。從楊(yang)房(fang)(fang)溝水(shui)電(dian)(dian)(dian)站(zhan)(zhan)一(yi)年多(duo)的(de)探索來看，總(zong)承(cheng)包(bao)方積極主動掌控(kong)施(shi)工(gong)(gong)(gong)進度、成本與風險控(kong)制(zhi)力更強(qiang)、安(an)全質(zhi)量管理(li)(li)更嚴格、施(shi)工(gong)(gong)(gong)信息化管理(li)(li)水(shui)平更高，達到了“降成本、補短板、提品(pin)質(zhi)、增效(xiao)益”的(de)目的(de)。楊(yang)房(fang)(fang)溝水(shui)電(dian)(dian)(dian)站(zhan)(zhan)設(she)(she)計施(shi)工(gong)(gong)(gong)總(zong)承(cheng)包(bao)模式(shi)(shi)的(de)實踐，開(kai)辟了國內百萬千瓦級(ji)大型水(shui)電(dian)(dian)(dian)站(zhan)(zhan)采用(yong)設(she)(she)計施(shi)工(gong)(gong)(gong)總(zong)承(cheng)包(bao)進行(xing)建(jian)設(she)(she)的(de)先河，被行(xing)業(ye)(ye)內譽為(wei)“第二(er)次魯布革沖擊”。
