進入(ru)5月(yue)，西(xi)北(bei)電(dian)(dian)網(wang)(wang)跨區外送(song)電(dian)(dian)量4次創下新(xin)高，5月(yue)16日跨區外送(song)電(dian)(dian)量最高達1.5222億(yi)千(qian)瓦時(shi)。截至(zhi)5月(yue)17日，西(xi)北(bei)電(dian)(dian)網(wang)(wang)外送(song)電(dian)(dian)量25.3億(yi)千(qian)瓦時(shi)，同比增長383.92%，相當于(yu)輸送(song)89萬噸標(biao)準煤，為緩解(jie)華(hua)中、華(hua)北(bei)電(dian)(dian)網(wang)(wang)用電(dian)(dian)緊張形勢作出了積極貢獻，西(xi)北(bei)送(song)端電(dian)(dian)網(wang)(wang)的作用得(de)到充分顯(xian)現。
隨著(zhu)我(wo)國工業生產用電(dian)量的(de)增(zeng)長，從4月中旬開始(shi)，華(hua)中、華(hua)北電(dian)網開始(shi)出(chu)現(xian)用電(dian)緊張形(xing)勢。據(ju)新華(hua)網5月16日報(bao)道，全國已有(you)16個(ge)省(sheng)份出(chu)現(xian)用電(dian)需(xu)求(qiu)持續旺盛局面。西北的(de)陜西、甘肅、青海、寧(ning)夏、新疆五省(sheng)（區(qu)）用電(dian)也(ye)呈(cheng)現(xian)增(zeng)長趨勢。
面對(dui)嚴峻考驗，西北電(dian)(dian)(dian)網公司(si)積極落實(shi)國家電(dian)(dian)(dian)網公司(si)確定(ding)的年度輸電(dian)(dian)(dian)計(ji)劃(hua)及跨區(qu)、跨省電(dian)(dian)(dian)能(neng)交易合同(tong)要求，充分發(fa)揮西北750千伏骨干網架初步建成后(hou)“大容量、遠距離、高效能(neng)”的輸送優勢(shi)，在保證(zheng)西北區(qu)域電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)量平衡(heng)的同(tong)時，全力(li)實(shi)施外(wai)送電(dian)(dian)(dian)計(ji)劃(hua)，以緩解華中、華北電(dian)(dian)(dian)網用(yong)電(dian)(dian)(dian)緊張形勢(shi)。
為(wei)了保證電(dian)網(wang)在大(da)量外送方式下安全穩定(ding)運行，西(xi)北公(gong)(gong)司早在今年年初就針(zhen)對電(dian)網(wang)運行中的薄弱環節(jie)，制定(ding)詳細的反事故預案，開(kai)展有針(zhen)對性的反事故演練(lian)，檢(jian)驗電(dian)網(wang)反事故能力，以提升調(diao)度運行人員(yuan)的應(ying)急(ji)能力。針(zhen)對電(dian)煤(mei)緊張形勢(shi)，西(xi)北公(gong)(gong)司一(yi)方面(mian)積極向政府匯(hui)報(bao)儲(chu)(chu)煤(mei)情況，另一(yi)方面(mian)加強(qiang)與電(dian)廠協調(diao)，強(qiang)化電(dian)煤(mei)監測(ce)，督(du)促電(dian)廠儲(chu)(chu)備電(dian)煤(mei)，保證電(dian)廠大(da)負荷、高效(xiao)能運轉。
國家電(dian)(dian)(dian)網(wang)西北(bei)電(dian)(dian)(dian)力調控(kong)分(fen)中(zhong)心(xin)精心(xin)安排(pai)電(dian)(dian)(dian)網(wang)運行方式，深度(du)挖掘電(dian)(dian)(dian)網(wang)輸電(dian)(dian)(dian)潛力，加強主要斷面輸電(dian)(dian)(dian)能力監測分(fen)析，滾動調整電(dian)(dian)(dian)力電(dian)(dian)(dian)量(liang)平衡計劃，保證全網(wang)及外送(song)電(dian)(dian)(dian)力電(dian)(dian)(dian)量(liang)平衡和備用容量(liang)充足，力保西北(bei)連接華中(zhong)電(dian)(dian)(dian)網(wang)的兩條電(dian)(dian)(dian)力輸送(song)大動脈暢通。
據統計，今年以(yi)來，西北(bei)電網3條輸送能(neng)力為(wei)811萬千瓦的電力外送通(tong)道跨(kua)區送電148.23億千瓦時，同比增長131.56%，相當于輸送508萬噸標準煤。
