11月11日(ri)，西北電網(wang)外(wai)(wai)(wai)送電量(liang)達到1.051億千(qian)(qian)瓦時，單日(ri)外(wai)(wai)(wai)送電量(liang)首(shou)次(ci)突破1億千(qian)(qian)瓦時大關，外(wai)(wai)(wai)送最大負荷達511萬千(qian)(qian)瓦，占目前西北外(wai)(wai)(wai)送總容量(liang)的83.63%，日(ri)外(wai)(wai)(wai)送電量(liang)和外(wai)(wai)(wai)送負荷均創歷史新高。
隨著寧東—山(shan)東±660千伏直流輸電示范(fan)工程順利投入試運行，西北(bei)電網外送最大容量達到(dao)611萬千瓦，西北(bei)外向(xiang)型(xing)、送出(chu)型(xing)、規模(mo)型(xing)堅強送端電網已(yi)初(chu)具(ju)規模(mo)，實現西北(bei)—華北(bei)、西北(bei)—華中聯網，將(jiang)黃河上游水電、煤電基地火電打(da)捆送往四川(chuan)、山(shan)東，有力(li)推(tui)進西北(bei)能源(yuan)資源(yuan)在更大范(fan)圍內優(you)化配置，為緩解(jie)冬季(ji)華中、華北(bei)電網缺電局面提供了強大的電力(li)支撐(cheng)。
為應(ying)對外送負荷(he)和網內(nei)用電負荷(he)高峰的到(dao)來，確保迎(ying)峰度冬(dong)和大(da)負荷(he)外送期間電網安全穩(wen)定(ding)運行，西(xi)北電網有限(xian)公(gong)司加快全網檢修和設備投產速度，目前(qian)已實現750千伏統一電網覆蓋西(xi)北五省（區），強化(hua)了西(xi)北送端網架結構。
西北公司(si)還(huan)指導主要火(huo)電(dian)(dian)(dian)(dian)(dian)(dian)發電(dian)(dian)(dian)(dian)(dian)(dian)企業簽訂了年利用5000小時(shi)(shi)以(yi)上的中長(chang)期(qi)(qi)合同(tong)，以(yi)黃河富余水電(dian)(dian)(dian)(dian)(dian)(dian)進行短期(qi)(qi)調節，充(chong)分發揮“電(dian)(dian)(dian)(dian)(dian)(dian)量庫(ku)”交易(yi)機制(zhi)，提前(qian)做(zuo)好(hao)外(wai)送(song)電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)量組織工(gong)作。同(tong)時(shi)(shi)，密切(qie)關(guan)注天氣變化(hua)，提高負荷預測的準確性，合理安排機組開機方式，加大電(dian)(dian)(dian)(dian)(dian)(dian)煤儲(chu)運工(gong)作力度，提前(qian)落(luo)實(shi)全網(wang)發用電(dian)(dian)(dian)(dian)(dian)(dian)平衡。此外(wai)，西北公司(si)還(huan)將440萬千(qian)瓦火(huo)電(dian)(dian)(dian)(dian)(dian)(dian)裝機列入外(wai)送(song)裝機序列，協(xie)調西北區域(yu)內(nei)主要水、火(huo)電(dian)(dian)(dian)(dian)(dian)(dian)廠留足(zu)備用容量，提前(qian)做(zuo)好(hao)電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)量平衡工(gong)作。
