11月(yue)11日(ri)，西北(bei)電(dian)(dian)(dian)網(wang)外送(song)電(dian)(dian)(dian)量(liang)(liang)達(da)到1.051億千瓦(wa)時(shi)，單(dan)日(ri)外送(song)電(dian)(dian)(dian)量(liang)(liang)首次突破1億千瓦(wa)時(shi)大(da)關，外送(song)最大(da)負荷達(da)511萬(wan)千瓦(wa)，占(zhan)目前(qian)西北(bei)外送(song)總容量(liang)(liang)的83.63%，日(ri)外送(song)電(dian)(dian)(dian)量(liang)(liang)和外送(song)負荷均創歷(li)史新高(gao)。
隨著寧東(dong)—山東(dong)±660千伏直(zhi)流輸電(dian)(dian)(dian)示范工程順利投入試運行，西(xi)北電(dian)(dian)(dian)網(wang)(wang)外送最大(da)容(rong)量達到(dao)611萬千瓦，西(xi)北外向型(xing)、送出型(xing)、規模(mo)(mo)型(xing)堅強送端電(dian)(dian)(dian)網(wang)(wang)已初具規模(mo)(mo)，實現西(xi)北—華北、西(xi)北—華中(zhong)聯網(wang)(wang)，將黃河上游水電(dian)(dian)(dian)、煤電(dian)(dian)(dian)基地火電(dian)(dian)(dian)打捆送往(wang)四川、山東(dong)，有力推進西(xi)北能源資源在更(geng)大(da)范圍內優化配置，為緩解冬季華中(zhong)、華北電(dian)(dian)(dian)網(wang)(wang)缺電(dian)(dian)(dian)局面提供(gong)了(le)強大(da)的電(dian)(dian)(dian)力支撐。
為應對外送負(fu)荷(he)和網內(nei)用電(dian)負(fu)荷(he)高峰(feng)的到來，確保迎峰(feng)度(du)冬和大負(fu)荷(he)外送期間電(dian)網安全(quan)穩定(ding)運行，西北(bei)電(dian)網有限公司加快全(quan)網檢(jian)修和設備投產(chan)速度(du)，目前(qian)已(yi)實現750千(qian)伏(fu)統一電(dian)網覆(fu)蓋西北(bei)五省（區），強化(hua)了西北(bei)送端網架(jia)結構。
西北(bei)(bei)公司(si)還指導主要(yao)火電(dian)(dian)(dian)(dian)(dian)發電(dian)(dian)(dian)(dian)(dian)企業簽訂(ding)了年(nian)利用5000小時以上的中長期合(he)同，以黃河富余水(shui)電(dian)(dian)(dian)(dian)(dian)進行短期調(diao)節，充分發揮“電(dian)(dian)(dian)(dian)(dian)量(liang)庫”交易(yi)機制，提(ti)前(qian)做好(hao)外(wai)送(song)(song)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)量(liang)組織工(gong)作(zuo)。同時，密(mi)切關注天氣變化，提(ti)高負荷預測的準確性，合(he)理(li)安排機組開機方(fang)式，加(jia)大電(dian)(dian)(dian)(dian)(dian)煤儲運工(gong)作(zuo)力(li)度，提(ti)前(qian)落實全網發用電(dian)(dian)(dian)(dian)(dian)平衡(heng)。此外(wai)，西北(bei)(bei)公司(si)還將(jiang)440萬千瓦火電(dian)(dian)(dian)(dian)(dian)裝機列入外(wai)送(song)(song)裝機序列，協調(diao)西北(bei)(bei)區域內主要(yao)水(shui)、火電(dian)(dian)(dian)(dian)(dian)廠留足備用容量(liang)，提(ti)前(qian)做好(hao)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)量(liang)平衡(heng)工(gong)作(zuo)。
