11月11日，西(xi)北電網外(wai)送(song)(song)電量(liang)達(da)到1.051億(yi)千瓦(wa)(wa)時，單日外(wai)送(song)(song)電量(liang)首次突破(po)1億(yi)千瓦(wa)(wa)時大(da)關，外(wai)送(song)(song)最大(da)負荷達(da)511萬(wan)千瓦(wa)(wa)，占目前西(xi)北外(wai)送(song)(song)總容量(liang)的(de)83.63%，日外(wai)送(song)(song)電量(liang)和外(wai)送(song)(song)負荷均創歷(li)史新高。
隨著寧東(dong)—山東(dong)±660千伏直流輸(shu)電(dian)(dian)示范工程順(shun)利投入試運行，西(xi)北(bei)(bei)電(dian)(dian)網(wang)外送(song)最(zui)大容量(liang)達到611萬千瓦，西(xi)北(bei)(bei)外向型(xing)、送(song)出(chu)型(xing)、規(gui)模型(xing)堅(jian)強送(song)端電(dian)(dian)網(wang)已初具規(gui)模，實現(xian)西(xi)北(bei)(bei)—華(hua)北(bei)(bei)、西(xi)北(bei)(bei)—華(hua)中聯網(wang)，將黃河(he)上游水電(dian)(dian)、煤電(dian)(dian)基地(di)火(huo)電(dian)(dian)打捆送(song)往(wang)四川、山東(dong)，有力推進西(xi)北(bei)(bei)能源(yuan)資源(yuan)在更大范圍內(nei)優化配置，為緩解冬季華(hua)中、華(hua)北(bei)(bei)電(dian)(dian)網(wang)缺電(dian)(dian)局面(mian)提供了強大的電(dian)(dian)力支撐。
為應(ying)對外送負荷(he)和網(wang)(wang)內用電(dian)負荷(he)高峰的到來，確保(bao)迎峰度(du)冬(dong)和大(da)負荷(he)外送期間電(dian)網(wang)(wang)安全(quan)穩定(ding)運行，西(xi)北(bei)電(dian)網(wang)(wang)有限公司加快全(quan)網(wang)(wang)檢修和設備投產速度(du)，目(mu)前已實現750千(qian)伏(fu)統一電(dian)網(wang)(wang)覆蓋西(xi)北(bei)五省（區），強化了西(xi)北(bei)送端網(wang)(wang)架結構。
西(xi)北(bei)(bei)公司還(huan)指導(dao)主要火(huo)電(dian)(dian)發電(dian)(dian)企業簽訂了年利用5000小時以(yi)上的中長(chang)期合同，以(yi)黃河富余(yu)水電(dian)(dian)進行(xing)短(duan)期調(diao)節，充(chong)分發揮“電(dian)(dian)量庫(ku)”交易機制，提前(qian)做(zuo)好外(wai)送(song)電(dian)(dian)力(li)電(dian)(dian)量組織工作(zuo)(zuo)(zuo)。同時，密切關注(zhu)天氣變化，提高(gao)負荷預測的準確性，合理安排機組開機方式，加大(da)電(dian)(dian)煤儲運工作(zuo)(zuo)(zuo)力(li)度(du)，提前(qian)落實(shi)全網(wang)發用電(dian)(dian)平衡(heng)。此外(wai)，西(xi)北(bei)(bei)公司還(huan)將440萬(wan)千瓦火(huo)電(dian)(dian)裝(zhuang)機列入外(wai)送(song)裝(zhuang)機序列，協調(diao)西(xi)北(bei)(bei)區域內主要水、火(huo)電(dian)(dian)廠留足備用容(rong)量，提前(qian)做(zuo)好電(dian)(dian)力(li)電(dian)(dian)量平衡(heng)工作(zuo)(zuo)(zuo)。
