為服務藏區經濟社會發展，國家電網公司在加快青海－西藏750千伏/±400千伏交直流聯網工程建設，從根本上解決西藏連續多年的枯水期嚴重缺電局面的同時，全力加快重點電源項目西藏巴河老虎嘴水電站工程建設。近日，該水電站兩臺機組順利通過72小時滿負荷試運行，正式并網發電。老虎嘴水電站總投資12.88億元，安裝3臺3.4萬千瓦立軸混流式水輪發電機組，總裝機容量10.2萬千瓦，是西藏地區迄今為止單機容量最大的水電站。全部機組并網發電后每日發電出力將達120-160萬千瓦時，年發電量可達4.9億千瓦時，替代此前投運的應急燃油機組發電后，相當于年節約柴油11.8萬噸，節省燃油發電成本6億元左右，并減少二氧化碳排放37.83萬噸，經濟和環保效益顯著。
近年(nian)來，西藏經濟(ji)快(kuai)速發(fa)展(zhan)，用電(dian)(dian)(dian)(dian)(dian)需求迅猛(meng)增長，電(dian)(dian)(dian)(dian)(dian)力(li)供(gong)需形勢嚴峻。按照國(guo)家(jia)部署(shu)，國(guo)家(jia)電(dian)(dian)(dian)(dian)(dian)網公(gong)司等(deng)各相關方面(mian)分(fen)別從建(jian)(jian)(jian)設(she)青藏電(dian)(dian)(dian)(dian)(dian)網聯(lian)網工(gong)(gong)程(cheng)、建(jian)(jian)(jian)設(she)重點電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)網項目、建(jian)(jian)(jian)設(she)應急燃油機組等(deng)方面(mian)多(duo)措并舉，加(jia)快(kuai)緩解電(dian)(dian)(dian)(dian)(dian)力(li)供(gong)需矛盾(dun)。2010年(nian)底建(jian)(jian)(jian)成(cheng)投運的應急燃油電(dian)(dian)(dian)(dian)(dian)站有效(xiao)緩解了供(gong)需緊張形勢，但(dan)燃油發(fa)電(dian)(dian)(dian)(dian)(dian)成(cheng)本高、環(huan)保壓(ya)力(li)大(da)。此(ci)次并網發(fa)電(dian)(dian)(dian)(dian)(dian)的老虎嘴水(shui)電(dian)(dian)(dian)(dian)(dian)站位(wei)于工(gong)(gong)布江(jiang)達縣巴河干流上(shang)，于2007年(nian)5月(yue)動工(gong)(gong)建(jian)(jian)(jian)設(she)，2011年(nian)4月(yue)15日開始(shi)下(xia)閘(zha)蓄(xu)水(shui)，5月(yue)15日庫水(shui)位(wei)蓄(xu)至(zhi)設(she)計蓄(xu)水(shui)高程(cheng)3297米。其投產發(fa)電(dian)(dian)(dian)(dian)(dian)，將(jiang)在有力(li)緩解供(gong)需矛盾(dun)，促(cu)進此(ci)前受(shou)電(dian)(dian)(dian)(dian)(dian)力(li)供(gong)應影響(xiang)的西藏地區(qu)建(jian)(jian)(jian)材(cai)建(jian)(jian)(jian)工(gong)(gong)、礦業等(deng)行業發(fa)展(zhan)的同時，有效(xiao)減少西藏燃油機組發(fa)電(dian)(dian)(dian)(dian)(dian)出力(li)，大(da)幅降低發(fa)電(dian)(dian)(dian)(dian)(dian)成(cheng)本，保護西藏生(sheng)態(tai)環(huan)境，經濟(ji)效(xiao)益和環(huan)保效(xiao)益顯著。
