進入5月，西(xi)(xi)北(bei)電(dian)網跨(kua)區(qu)(qu)外送(song)電(dian)量(liang)(liang)4次創下新高(gao)，5月16日跨(kua)區(qu)(qu)外送(song)電(dian)量(liang)(liang)最高(gao)達1.5222億千瓦(wa)時(shi)。截(jie)至5月17日，西(xi)(xi)北(bei)電(dian)網外送(song)電(dian)量(liang)(liang)25.3億千瓦(wa)時(shi)，同比增長(chang)383.92%，相當(dang)于輸送(song)89萬噸(dun)標準煤，為緩解華中(zhong)、華北(bei)電(dian)網用電(dian)緊張形(xing)勢(shi)作出了積極(ji)貢獻(xian)，西(xi)(xi)北(bei)送(song)端(duan)電(dian)網的作用得到充分顯(xian)現。
隨著我國(guo)工業(ye)生(sheng)產(chan)用(yong)電量的增長(chang)，從4月中(zhong)旬開始，華中(zhong)、華北(bei)電網(wang)開始出現用(yong)電緊(jin)張(zhang)形勢。據新華網(wang)5月16日報道，全國(guo)已有16個省份出現用(yong)電需求持續旺(wang)盛(sheng)局面。西北(bei)的陜西、甘肅、青(qing)海、寧(ning)夏、新疆(jiang)五(wu)省（區）用(yong)電也呈現增長(chang)趨勢。
面對嚴峻(jun)考(kao)驗(yan)，西北電(dian)(dian)網(wang)公(gong)司(si)(si)積極(ji)落實國家電(dian)(dian)網(wang)公(gong)司(si)(si)確定的年度輸電(dian)(dian)計(ji)劃及跨區、跨省電(dian)(dian)能(neng)交易合同(tong)(tong)要求，充分(fen)發揮西北750千(qian)伏骨干網(wang)架初步建成后“大容量(liang)、遠距離、高效能(neng)”的輸送優勢(shi)，在保證(zheng)西北區域電(dian)(dian)力(li)電(dian)(dian)量(liang)平衡的同(tong)(tong)時，全力(li)實施(shi)外送電(dian)(dian)計(ji)劃，以(yi)緩(huan)解(jie)華中、華北電(dian)(dian)網(wang)用電(dian)(dian)緊張形勢(shi)。
為了保證(zheng)電(dian)(dian)網(wang)在大量外送方(fang)式下安全穩定運(yun)行(xing)，西北公司早在今(jin)年(nian)年(nian)初就(jiu)針對(dui)電(dian)(dian)網(wang)運(yun)行(xing)中的(de)(de)薄弱環節，制(zhi)定詳(xiang)細(xi)的(de)(de)反事故預(yu)案，開展有針對(dui)性(xing)的(de)(de)反事故演練，檢驗電(dian)(dian)網(wang)反事故能(neng)(neng)力，以(yi)提升調度運(yun)行(xing)人員的(de)(de)應(ying)急能(neng)(neng)力。針對(dui)電(dian)(dian)煤(mei)緊張(zhang)形勢(shi)，西北公司一方(fang)面積極向(xiang)政府匯報儲煤(mei)情況，另一方(fang)面加強與電(dian)(dian)廠(chang)(chang)協調，強化(hua)電(dian)(dian)煤(mei)監測，督促電(dian)(dian)廠(chang)(chang)儲備電(dian)(dian)煤(mei)，保證(zheng)電(dian)(dian)廠(chang)(chang)大負荷、高效能(neng)(neng)運(yun)轉。
國家(jia)電(dian)(dian)(dian)網(wang)(wang)西北電(dian)(dian)(dian)力(li)(li)調控分(fen)中(zhong)(zhong)心精心安排(pai)電(dian)(dian)(dian)網(wang)(wang)運行方式，深度(du)挖掘(jue)電(dian)(dian)(dian)網(wang)(wang)輸電(dian)(dian)(dian)潛力(li)(li)，加強主要斷面輸電(dian)(dian)(dian)能力(li)(li)監測分(fen)析，滾動調整電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)量(liang)平衡計劃，保證全網(wang)(wang)及外送(song)電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)量(liang)平衡和備用容量(liang)充足，力(li)(li)保西北連(lian)接華中(zhong)(zhong)電(dian)(dian)(dian)網(wang)(wang)的兩條(tiao)電(dian)(dian)(dian)力(li)(li)輸送(song)大動脈暢(chang)通。
據統(tong)計，今年以來，西北電(dian)網(wang)3條輸(shu)送能力為811萬(wan)千瓦(wa)的(de)電(dian)力外送通道跨區送電(dian)148.23億(yi)千瓦(wa)時，同比(bi)增長(chang)131.56%，相當于輸(shu)送508萬(wan)噸標(biao)準煤。
