國家電(dian)網(wang)公司積極(ji)落實(shi)黨中央、國務院關于擴內需、調(diao)結構、保(bao)增長的重大(da)決(jue)策，加大(da)西(xi)北地區電(dian)網(wang)建設投入力度，加快完善西(xi)北750千伏主網(wang)架，全(quan)力推動西(xi)北主網(wang)與新(xin)疆、西(xi)藏聯網(wang)工程,統籌推進(jin)330千伏及以(yi)下(xia)各級電(dian)網(wang)協調(diao)發展。
2009年(nian)，國(guo)家電(dian)網計劃(hua)投(tou)(tou)資(zi)313.05億元(yuan)，較上年(nian)增長30.1%，其(qi)中(zhong)750千(qian)(qian)伏電(dian)網建(jian)(jian)設(she)工(gong)(gong)程(cheng)投(tou)(tou)資(zi)139億元(yuan)，占投(tou)(tou)資(zi)總量的(de)44.4%。計劃(hua)開(kai)工(gong)(gong)110千(qian)(qian)伏及以上輸變電(dian)項目11015公里/4027.3萬(wan)千(qian)(qian)伏安，投(tou)(tou)產8843公里/2915萬(wan)千(qian)(qian)伏安。在(zai)加大投(tou)(tou)資(zi)的(de)同時，國(guo)家電(dian)網將嚴格控(kong)制工(gong)(gong)程(cheng)造價，提高投(tou)(tou)資(zi)效率，把資(zi)金重點用于完善750千(qian)(qian)伏骨干(gan)網架，推進大負荷項目和(he)拉(la)動(dong)內需的(de)城鄉電(dian)網建(jian)(jian)設(she)與(yu)改(gai)造工(gong)(gong)程(cheng)項目，繼續落(luo)實(shi)農網建(jian)(jian)設(she)與(yu)改(gai)造規劃(hua)，扎實(shi)開(kai)展新農村電(dian)氣(qi)化(hua)建(jian)(jian)設(she)，為拉(la)動(dong)內需、促(cu)進西北地區(qu)經(jing)濟增長做貢獻。
2008年，西(xi)北(bei)電(dian)(dian)網(wang)建設與改造完成投(tou)資240.5億元,投(tou)產110千(qian)伏(fu)(fu)及以上線(xian)路8211.71公里，變電(dian)(dian)容量2061.15萬千(qian)伏(fu)(fu)安，創歷史最高。750千(qian)伏(fu)(fu)蘭州東(dong)-銀川東(dong)、西(xi)寧(ning)-官亭等重點工(gong)程相繼(ji)投(tou)入運行，靈寶二期擴(kuo)建（75萬千(qian)瓦）、寶雞-德陽（300萬千(qian)瓦）、寧(ning)東(dong)-山東(dong)(400萬千(qian)瓦)直流聯網(wang)工(gong)程全面(mian)開工(gong)建設，帶動(dong)了西(xi)北(bei)大煤電(dian)(dian)、大水電(dian)(dian)、大風(feng)電(dian)(dian)基地集約化開發，促進了地區(qu)經濟社會發展。
“十一五(wu)”末，國家電(dian)(dian)網公(gong)司(si)將在西(xi)(xi)北建(jian)成(cheng)750千(qian)(qian)伏變電(dian)(dian)站27座，變電(dian)(dian)容量5730萬(wan)千(qian)(qian)伏安，750千(qian)(qian)伏線(xian)路12420公(gong)里，實(shi)現(xian)新疆、西(xi)(xi)藏電(dian)(dian)網與西(xi)(xi)北主網互聯，西(xi)(xi)北電(dian)(dian)網外送(song)能(neng)力達(da)到886萬(wan)千(qian)(qian)瓦，逐步(bu)形成(cheng)西(xi)(xi)北水(shui)火風(feng)電(dian)(dian)大(da)規模打捆外送(song)的格局。充分發(fa)揮(hui)國家電(dian)(dian)網遠(yuan)距(ju)離、大(da)容量、高效率、低(di)損耗優化(hua)配(pei)置資源(yuan)的能(neng)力，在保(bao)障國家能(neng)源(yuan)安全、服務(wu)經濟發(fa)展和促進資源(yuan)優化(hua)配(pei)置方面(mian)發(fa)揮(hui)更加重要的作(zuo)用。
