進(jin)入5月，西(xi)北(bei)電(dian)(dian)網(wang)跨(kua)區(qu)外送(song)(song)電(dian)(dian)量(liang)4次創下新(xin)高，5月16日跨(kua)區(qu)外送(song)(song)電(dian)(dian)量(liang)最高達(da)1.5222億千瓦時(shi)。截(jie)至5月17日，西(xi)北(bei)電(dian)(dian)網(wang)外送(song)(song)電(dian)(dian)量(liang)25.3億千瓦時(shi)，同比(bi)增長383.92%，相當于輸送(song)(song)89萬噸標準(zhun)煤，為(wei)緩(huan)解華中(zhong)、華北(bei)電(dian)(dian)網(wang)用(yong)電(dian)(dian)緊張形(xing)勢作出了積極貢獻，西(xi)北(bei)送(song)(song)端電(dian)(dian)網(wang)的作用(yong)得(de)到充分顯(xian)現。
隨著我國工業生產用電(dian)量的增(zeng)長(chang)，從(cong)4月中旬開始，華中、華北(bei)電(dian)網(wang)開始出現用電(dian)緊張形(xing)勢(shi)。據新華網(wang)5月16日報(bao)道，全(quan)國已有16個省份出現用電(dian)需(xu)求持續旺盛局面(mian)。西北(bei)的陜(shan)西、甘肅、青(qing)海(hai)、寧夏、新疆五省（區(qu)）用電(dian)也呈現增(zeng)長(chang)趨勢(shi)。
面對嚴峻考驗(yan)，西北電(dian)網(wang)(wang)公(gong)司積(ji)極落實(shi)國家電(dian)網(wang)(wang)公(gong)司確定的年度輸電(dian)計劃及跨區(qu)、跨省電(dian)能交易合同要求，充分發揮西北750千伏骨(gu)干網(wang)(wang)架初步建成后“大(da)容量(liang)、遠距(ju)離、高(gao)效(xiao)能”的輸送優勢，在保證(zheng)西北區(qu)域電(dian)力電(dian)量(liang)平衡(heng)的同時(shi)，全力實(shi)施外送電(dian)計劃，以緩解華中、華北電(dian)網(wang)(wang)用電(dian)緊張形勢。
為(wei)了保(bao)證(zheng)電(dian)網在大(da)量外送方(fang)式下安(an)全(quan)穩定運(yun)(yun)行(xing)，西北公(gong)(gong)司(si)早(zao)在今年年初(chu)就針(zhen)對電(dian)網運(yun)(yun)行(xing)中的薄(bo)弱環(huan)節，制定詳細的反(fan)(fan)(fan)事故(gu)預案(an)，開(kai)展有(you)針(zhen)對性(xing)的反(fan)(fan)(fan)事故(gu)演練，檢驗電(dian)網反(fan)(fan)(fan)事故(gu)能(neng)力，以提升調(diao)度(du)運(yun)(yun)行(xing)人員的應急(ji)能(neng)力。針(zhen)對電(dian)煤緊張形勢，西北公(gong)(gong)司(si)一方(fang)面(mian)積(ji)極(ji)向政(zheng)府匯(hui)報儲煤情況，另(ling)一方(fang)面(mian)加強與電(dian)廠協調(diao)，強化(hua)電(dian)煤監測(ce)，督促(cu)電(dian)廠儲備電(dian)煤，保(bao)證(zheng)電(dian)廠大(da)負荷、高效(xiao)能(neng)運(yun)(yun)轉。
國(guo)家電(dian)網(wang)西(xi)北電(dian)力調(diao)控(kong)分(fen)中心精心安(an)排電(dian)網(wang)運行方式，深度(du)挖(wa)掘電(dian)網(wang)輸電(dian)潛力，加強(qiang)主要斷面輸電(dian)能力監測分(fen)析，滾動調(diao)整電(dian)力電(dian)量(liang)平(ping)衡(heng)計劃，保證全網(wang)及(ji)外送電(dian)力電(dian)量(liang)平(ping)衡(heng)和備(bei)用容量(liang)充足，力保西(xi)北連(lian)接華中電(dian)網(wang)的兩(liang)條電(dian)力輸送大動脈暢通。
據(ju)統計(ji)，今年以來，西北(bei)電(dian)(dian)網3條輸(shu)送(song)(song)能力為811萬(wan)千瓦的電(dian)(dian)力外(wai)送(song)(song)通道跨區送(song)(song)電(dian)(dian)148.23億千瓦時，同比(bi)增長131.56%，相當于輸(shu)送(song)(song)508萬(wan)噸標準煤。
