11月25日，受國(guo)家發改委的委托，中國(guo)國(guo)際工(gong)程咨詢公司召開了(le)西北（寧東(dong)(dong)）—華北（山東(dong)(dong)）±660千伏直流輸電(dian)工(gong)程項目申(shen)請核準報告評估會議。該(gai)項目順利通過(guo)評估。
西北(bei)（寧東(dong)）—華北(bei)（山東(dong)）±660千(qian)伏(fu)直(zhi)流輸(shu)電(dian)(dian)工(gong)程(cheng)，是我(wo)國(guo)第(di)一個±660千(qian)伏(fu)直(zhi)流輸(shu)電(dian)(dian)工(gong)程(cheng)，也是寧夏(xia)首個“西電(dian)(dian)東(dong)送(song)”工(gong)程(cheng)，已(yi)取(qu)得國(guo)土資源部、環境保護部、水利部等國(guo)家主(zhu)管部門的批復。本(ben)次評估是通過國(guo)家發(fa)改委核(he)準前的最后(hou)一項工(gong)作(zuo)。
工(gong)(gong)程(cheng)西起寧(ning)夏銀(yin)川東(dong)(dong)750千(qian)伏變電站(zhan)，東(dong)(dong)至山(shan)(shan)東(dong)(dong)青(qing)島換(huan)(huan)流(liu)站(zhan)，途經寧(ning)夏、陜西、山(shan)(shan)西、河北、山(shan)(shan)東(dong)(dong)五省（區），線(xian)路(lu)(lu)全長1335千(qian)米。工(gong)(gong)程(cheng)可(ke)將黃(huang)河上游水電資(zi)源(yuan)與寧(ning)東(dong)(dong)火電資(zi)源(yuan)打捆送(song)往山(shan)(shan)東(dong)(dong)，實(shi)現資(zi)源(yuan)優化(hua)配置。主要(yao)建設內容包括，新建寧(ning)夏銀(yin)川東(dong)(dong)（寧(ning)東(dong)(dong)）換(huan)(huan)流(liu)站(zhan)工(gong)(gong)程(cheng)、山(shan)(shan)東(dong)(dong)青(qing)島換(huan)(huan)流(liu)站(zhan)工(gong)(gong)程(cheng)、直流(liu)線(xian)路(lu)(lu)工(gong)(gong)程(cheng)、直流(liu)接地(di)極(ji)及接地(di)極(ji)線(xian)路(lu)(lu)工(gong)(gong)程(cheng)，配套建設相(xiang)應通(tong)信和二次系統工(gong)(gong)程(cheng)。全部(bu)工(gong)(gong)程(cheng)預計2010年建成投運(yun)。
此(ci)次評估認(ren)為，西(xi)北(bei)（寧東(dong)(dong)(dong)）—華北(bei)（山(shan)東(dong)(dong)(dong)）±660千(qian)伏直(zhi)流輸(shu)電(dian)(dian)工程是優(you)化(hua)資源配置、促(cu)進(jin)西(xi)部(bu)經(jing)濟社會發(fa)展(zhan)，符合“西(xi)電(dian)(dian)東(dong)(dong)(dong)送(song)(song)、全國(guo)聯(lian)網”總體格局的(de)水火打捆送(song)(song)電(dian)(dian)項目。工程充(chong)分利用西(xi)部(bu)特(te)別是寧東(dong)(dong)(dong)地區豐富(fu)資源，轉變一(yi)次能(neng)(neng)源優(you)勢(shi)，向山(shan)東(dong)(dong)(dong)負荷(he)中心送(song)(song)電(dian)(dian)，對于滿足(zu)山(shan)東(dong)(dong)(dong)省經(jing)濟發(fa)展(zhan)對電(dian)(dian)力(li)(li)的(de)需(xu)求，調整我國(guo)能(neng)(neng)源結構，減輕一(yi)次能(neng)(neng)源運輸(shu)壓力(li)(li)，加強環境保(bao)護，實(shi)現經(jing)濟可持續發(fa)展(zhan)具有十分重要的(de)意(yi)義。根據電(dian)(dian)力(li)(li)平衡結果和(he)西(xi)北(bei)電(dian)(dian)網的(de)裝機規劃，2010年以后及相(xiang)當長的(de)一(yi)段(duan)時(shi)間內，西(xi)北(bei)電(dian)(dian)網具備向山(shan)東(dong)(dong)(dong)持續穩定送(song)(song)電(dian)(dian)400萬千(qian)瓦的(de)能(neng)(neng)力(li)(li)。
該(gai)工程使西北電(dian)(dian)(dian)網與周邊電(dian)(dian)(dian)網聯系更加(jia)緊(jin)密，電(dian)(dian)(dian)網的(de)安全穩定性進一步提高，優(you)化了西北地(di)區能源(yuan)資源(yuan)配置(zhi)能力，具有良(liang)好的(de)經濟社會效益。
