國(guo)家電網(wang)(wang)公(gong)司積極(ji)落實黨中央、國(guo)務院(yuan)關于(yu)擴(kuo)內需、調結構、保增長的重大(da)決(jue)策，加大(da)西(xi)北(bei)地區(qu)電網(wang)(wang)建設(she)投入力度，加快完善西(xi)北(bei)750千伏(fu)主(zhu)網(wang)(wang)架，全力推動西(xi)北(bei)主(zhu)網(wang)(wang)與新(xin)疆、西(xi)藏聯網(wang)(wang)工程,統(tong)籌推進(jin)330千伏(fu)及以下(xia)各(ge)級電網(wang)(wang)協調發(fa)展(zhan)。
2009年(nian)，國家電(dian)(dian)網計劃投(tou)資(zi)313.05億元，較上年(nian)增長(chang)30.1%，其中750千(qian)(qian)伏(fu)(fu)電(dian)(dian)網建設工(gong)(gong)程投(tou)資(zi)139億元，占投(tou)資(zi)總量的(de)44.4%。計劃開工(gong)(gong)110千(qian)(qian)伏(fu)(fu)及以(yi)上輸變電(dian)(dian)項(xiang)目(mu)11015公(gong)里/4027.3萬千(qian)(qian)伏(fu)(fu)安(an)，投(tou)產8843公(gong)里/2915萬千(qian)(qian)伏(fu)(fu)安(an)。在加大投(tou)資(zi)的(de)同時，國家電(dian)(dian)網將嚴格控(kong)制(zhi)工(gong)(gong)程造(zao)價(jia)，提高(gao)投(tou)資(zi)效率，把資(zi)金重點(dian)用于完善(shan)750千(qian)(qian)伏(fu)(fu)骨干(gan)網架，推進(jin)大負荷項(xiang)目(mu)和拉動內需的(de)城鄉電(dian)(dian)網建設與改(gai)造(zao)工(gong)(gong)程項(xiang)目(mu)，繼(ji)續落實(shi)農網建設與改(gai)造(zao)規(gui)劃，扎(zha)實(shi)開展新農村電(dian)(dian)氣化建設，為拉動內需、促(cu)進(jin)西北(bei)地區經濟增長(chang)做貢獻(xian)。
2008年，西(xi)北電網建(jian)設與改造完(wan)成投(tou)(tou)資(zi)240.5億元,投(tou)(tou)產110千(qian)(qian)(qian)伏(fu)及以上線路8211.71公里，變電容量2061.15萬千(qian)(qian)(qian)伏(fu)安，創歷史最高(gao)。750千(qian)(qian)(qian)伏(fu)蘭州東(dong)(dong)(dong)-銀川東(dong)(dong)(dong)、西(xi)寧(ning)-官亭等重點工程相繼投(tou)(tou)入運(yun)行，靈(ling)寶二期擴建(jian)（75萬千(qian)(qian)(qian)瓦）、寶雞-德(de)陽(yang)（300萬千(qian)(qian)(qian)瓦）、寧(ning)東(dong)(dong)(dong)-山東(dong)(dong)(dong)(400萬千(qian)(qian)(qian)瓦)直流聯網工程全(quan)面開工建(jian)設，帶動(dong)了西(xi)北大煤電、大水電、大風電基地(di)集約化(hua)開發，促進了地(di)區經(jing)濟社會發展。
“十一五(wu)”末，國(guo)家電(dian)網(wang)公(gong)司將在西(xi)(xi)(xi)北(bei)(bei)建成750千伏(fu)變電(dian)站27座，變電(dian)容(rong)量5730萬千伏(fu)安，750千伏(fu)線路(lu)12420公(gong)里，實現新(xin)疆(jiang)、西(xi)(xi)(xi)藏電(dian)網(wang)與(yu)西(xi)(xi)(xi)北(bei)(bei)主網(wang)互聯，西(xi)(xi)(xi)北(bei)(bei)電(dian)網(wang)外送(song)(song)能力達到886萬千瓦，逐步形成西(xi)(xi)(xi)北(bei)(bei)水火風電(dian)大規模打(da)捆外送(song)(song)的格局。充(chong)分發(fa)揮國(guo)家電(dian)網(wang)遠距離、大容(rong)量、高效率、低損耗優(you)化配置資(zi)源的能力，在保障國(guo)家能源安全、服務經濟發(fa)展和促進(jin)資(zi)源優(you)化配置方面發(fa)揮更加重(zhong)要的作用。
