4月21日至(zhi)28日，南方電(dian)(dian)網(wang)(wang)所(suo)屬(shu)貴(gui)(gui)州電(dian)(dian)網(wang)(wang)統調火電(dian)(dian)廠缺煤停機容(rong)量降(jiang)至(zhi)570萬(wan)(wan)千(qian)瓦(wa)，連續(xu)一周低于(yu)(yu)600萬(wan)(wan)千(qian)瓦(wa)的紅(hong)色預警(jing)標準，解除了電(dian)(dian)煤紅(hong)色預警(jing)。截至(zhi)目前，貴(gui)(gui)州電(dian)(dian)網(wang)(wang)存煤233.2萬(wan)(wan)噸，可用天數8天，缺煤停機容(rong)量540萬(wan)(wan)千(qian)瓦(wa)，貴(gui)(gui)州電(dian)(dian)網(wang)(wang)仍處于(yu)(yu)電(dian)(dian)煤黃色預警(jing)狀(zhuang)態。
針對(dui)(dui)2月(yue)份以(yi)來(lai)貴(gui)(gui)州電(dian)(dian)(dian)(dian)(dian)(dian)煤(mei)(mei)(mei)進入紅色(se)預(yu)(yu)警的(de)嚴(yan)峻(jun)局面，南方(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)網積(ji)極協(xie)調(diao)、及時(shi)(shi)預(yu)(yu)警，制(zhi)定應急預(yu)(yu)案，全力(li)保障(zhang)了(le)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)供(gong)應。一(yi)是靈活調(diao)劑省(sheng)間電(dian)(dian)(dian)(dian)(dian)(dian)力(li)余(yu)缺。按照“以(yi)煤(mei)(mei)(mei)定電(dian)(dian)(dian)(dian)(dian)(dian)”的(de)原則安排(pai)貴(gui)(gui)州送電(dian)(dian)(dian)(dian)(dian)(dian)，1－4月(yue)調(diao)減貴(gui)(gui)州外送電(dian)(dian)(dian)(dian)(dian)(dian)量81億千瓦時(shi)(shi)，并(bing)充(chong)分利(li)(li)用(yong)通道能力(li)增加云電(dian)(dian)(dian)(dian)(dian)(dian)送出，有效保障(zhang)了(le)貴(gui)(gui)州、廣(guang)東的(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)供(gong)應和(he)(he)西電(dian)(dian)(dian)(dian)(dian)(dian)東送年度(du)計劃的(de)執行(xing)(xing)。二是優化水(shui)庫(ku)調(diao)度(du)。針對(dui)(dui)2016年貴(gui)(gui)州來(lai)水(shui)嚴(yan)重偏枯情況，南方(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)網優化貴(gui)(gui)州烏江、北盤(pan)江梯級水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)發電(dian)(dian)(dian)(dian)(dian)(dian)運行(xing)(xing)，安排(pai)洪家渡、構皮灘等主(zhu)要水(shui)庫(ku)保水(shui)、蓄水(shui)，完(wan)成2016年底貴(gui)(gui)州水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)蓄能45億千瓦時(shi)(shi)目(mu)標，最(zui)大(da)限度(du)保證了(le)汛前水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)頂峰(feng)發電(dian)(dian)(dian)(dian)(dian)(dian)和(he)(he)緊急備用(yong)能力(li)。根(gen)據氣象會商和(he)(he)汛前協(xie)調(diao)信息(xi)，充(chong)分利(li)(li)用(yong)汛期(qi)水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)資源(yuan)，優化烏江、北盤(pan)江流域等梯級調(diao)度(du)，提高水(shui)能利(li)(li)用(yong)率。三是督(du)促(cu)電(dian)(dian)(dian)(dian)(dian)(dian)廠加大(da)存(cun)煤(mei)(mei)(mei)力(li)度(du)。密切跟蹤(zong)貴(gui)(gui)州電(dian)(dian)(dian)(dian)(dian)(dian)煤(mei)(mei)(mei)供(gong)應情況，依靠貴(gui)(gui)州省(sheng)政府組織各火電(dian)(dian)(dian)(dian)(dian)(dian)廠繼續加大(da)電(dian)(dian)(dian)(dian)(dian)(dian)煤(mei)(mei)(mei)采購力(li)度(du)，提高電(dian)(dian)(dian)(dian)(dian)(dian)廠電(dian)(dian)(dian)(dian)(dian)(dian)煤(mei)(mei)(mei)存(cun)量，加強(qiang)機組運行(xing)(xing)維護和(he)(he)超(chao)低排(pai)放改造工作。通過(guo)加強(qiang)多方(fang)(fang)協(xie)調(diao)聯動，采取多種有效措施，公(gong)司(si)最(zui)大(da)限度(du)降低電(dian)(dian)(dian)(dian)(dian)(dian)煤(mei)(mei)(mei)供(gong)應不足(zu)對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)供(gong)應產生(sheng)的(de)影響。
