8月4日18時55分，750千(qian)(qian)伏蘭州東—白銀—銀川東輸變電(dian)工(gong)程24小時試運結束，正(zheng)式投入運行(xing)。這(zhe)是西北電(dian)網(wang)投產的第二個750千(qian)(qian)伏輸變電(dian)工(gong)程，橫(heng)跨甘(gan)肅、寧夏(xia)兩省（區）。
這(zhe)一工程的投運(yun)，標(biao)志(zhi)西(xi)電(dian)(dian)(dian)東送(song)北通(tong)道建(jian)設(she)取得重大進(jin)展，西(xi)北電(dian)(dian)(dian)網具備了水火風電(dian)(dian)(dian)打捆(kun)大規模外送(song)的條件(jian)。該工程對于(yu)加(jia)快黃(huang)河上游水電(dian)(dian)(dian)基(ji)地(di)(di)、甘肅千萬千瓦級(ji)風電(dian)(dian)(dian)基(ji)地(di)(di)、寧東大型煤電(dian)(dian)(dian)基(ji)地(di)(di)外送(song)，加(jia)快實施西(xi)北“外向型、送(song)出型、規模型”堅強送(song)端電(dian)(dian)(dian)網發展戰略，實現西(xi)北能源資(zi)源在全(quan)國優(you)化(hua)配(pei)置具有重要意義。
西(xi)北(bei)電(dian)網(wang)有限(xian)公司將以此(ci)項工(gong)程(cheng)投產為契(qi)機，全(quan)面加快在建(jian)(jian)750千伏“22站38線”工(gong)程(cheng)建(jian)(jian)設，確保到(dao)年底初步(bu)建(jian)(jian)成(cheng)750千伏骨(gu)干網(wang)架，支撐西(xi)北(bei)大(da)煤電(dian)、大(da)風(feng)電(dian)、大(da)水(shui)電(dian)集約化開發(fa)建(jian)(jian)設，促進西(xi)北(bei)能源資(zi)源優勢轉化。
