受強冷空氣(qi)入侵影響(xiang)，江(jiang)西近日來氣(qi)溫(wen)急劇下降，全省用(yong)電(dian)(dian)量驟(zou)然拉(la)升。1月15日全網最(zui)高(gao)用(yong)電(dian)(dian)負荷達到802.9萬(wan)千瓦，當日用(yong)電(dian)(dian)量達1.53億千瓦時，雙雙創(chuang)下歷(li)史最(zui)高(gao)紀錄。在部分省市相繼(ji)出現(xian)限電(dian)(dian)的(de)形勢下，江(jiang)西電(dian)(dian)網克服惡(e)劣天氣(qi)影響(xiang)及全國(guo)性的(de)電(dian)(dian)煤供應緊張等困難，未(wei)拉(la)閘限電(dian)(dian)。
據介紹，經(jing)濟(ji)高速增長、氣溫驟(zou)然下降是促(cu)使(shi)我(wo)省(sheng)冬季用電負荷迅速攀升的(de)主(zhu)要原(yuan)因。2008年1月以(yi)來，全省(sheng)工業經(jing)濟(ji)繼續(xu)呈(cheng)現持續(xu)快(kuai)速增長勢頭，全網(wang)日(ri)最大用電負荷均達到(dao)700萬(wan)千瓦以(yi)上，電網(wang)保持高負荷運行狀態。
1月(yue)12日(ri)凌晨(chen)，來自貝(bei)加爾湖地區的強冷空氣(qi)入侵江西(xi)，全省(sheng)出(chu)現(xian)明(ming)顯大風降溫天氣(qi)，局(ju)部地區出(chu)現(xian)雨雪冰凍天氣(qi)。因氣(qi)溫下(xia)降，取暖負(fu)荷(he)(he)增長明(ming)顯，拉動(dong)全省(sheng)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)負(fu)荷(he)(he)屢創新(xin)高(gao)(gao)。1月(yue)14日(ri)11：30，全網最高(gao)(gao)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)負(fu)荷(he)(he)達到788.5萬(wan)千(qian)(qian)瓦(wa)，1月(yue)15日(ri)11：25，全網最高(gao)(gao)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)負(fu)荷(he)(he)沖至802.9萬(wan)千(qian)(qian)瓦(wa)，突破去年迎峰(feng)度夏800.2萬(wan)千(qian)(qian)瓦(wa)的峰(feng)值，當日(ri)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)量達1.53億千(qian)(qian)瓦(wa)時，用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)負(fu)荷(he)(he)及日(ri)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)量雙雙創下(xia)歷史最高(gao)(gao)紀(ji)錄。15日(ri)，江西(xi)電(dian)(dian)(dian)網火電(dian)(dian)(dian)機組(zu)滿發輸(shu)送710萬(wan)千(qian)(qian)瓦(wa)電(dian)(dian)(dian)力(li)，水(shui)電(dian)(dian)(dian)頂峰(feng)90萬(wan)千(qian)(qian)瓦(wa)左右，并通過(guo)外購8萬(wan)千(qian)(qian)瓦(wa)電(dian)(dian)(dian)力(li)，確保(bao)了全省(sheng)電(dian)(dian)(dian)力(li)可(ke)靠供應。
記者(zhe)從江(jiang)西(xi)電(dian)網(wang)(wang)調度中心了解到，全省(sheng)冬季大負荷還將持續一段時(shi)期，受(shou)電(dian)煤供(gong)(gong)應(ying)緊張、火電(dian)機組(zu)缺陷(xian)、水(shui)電(dian)來水(shui)不足及惡劣天氣等因素影響，江(jiang)西(xi)電(dian)網(wang)(wang)迎峰度冬面(mian)臨嚴峻考(kao)驗。為此，公(gong)司正會同省(sheng)政(zheng)府有(you)關部門積(ji)極采取(qu)措施(shi)，最大努力(li)以(yi)確保今(jin)年(nian)春節期間全省(sheng)電(dian)力(li)可靠供(gong)(gong)應(ying)。一是配合做好電(dian)煤協調工作，加大電(dian)煤調運力(li)度，密切關注主力(li)電(dian)廠電(dian)煤供(gong)(gong)應(ying)情況，科學安排電(dian)網(wang)(wang)調度運行方式；二是做好惡劣天氣下(xia)電(dian)網(wang)(wang)運行設備的巡視和維(wei)護，制定電(dian)網(wang)(wang)防(fang)大風抗冰災措施(shi)，組(zu)織力(li)量及時(shi)整治設備缺陷(xian)、排除各種突發故障(zhang)，確保電(dian)網(wang)(wang)安全穩定運行；三是積(ji)極增購外網(wang)(wang)電(dian)力(li)以(yi)填補本省(sheng)電(dian)力(li)供(gong)(gong)應(ying)缺口，1月(yue)至2月(yue)力(li)爭外購50萬千(qian)瓦(wa)的電(dian)力(li)緩解高峰時(shi)供(gong)(gong)電(dian)壓力(li)。
相關部門表示，迫于電煤供應緊張、惡劣氣侯自然災害對電網運行造成的壓力，今年全國電力迎峰度冬形勢趨緊，部分省市相繼發生拉閘限電的現象。針對供電形勢可能進一步惡化，江西公司正協同政府有關部門，全力做好電網預警狀態下的電力有序供應預案并向社會發布，號召工礦企業及部分高耗能企業主動采取避峰、讓峰用電措施。
