受強冷空氣(qi)入(ru)侵影響，江(jiang)西(xi)近日(ri)來氣(qi)溫急劇下(xia)(xia)(xia)降，全(quan)省用電(dian)(dian)量驟(zou)然拉(la)升(sheng)。1月15日(ri)全(quan)網最(zui)高(gao)(gao)用電(dian)(dian)負(fu)荷達(da)到802.9萬千(qian)瓦(wa)，當日(ri)用電(dian)(dian)量達(da)1.53億千(qian)瓦(wa)時(shi)，雙雙創下(xia)(xia)(xia)歷史最(zui)高(gao)(gao)紀錄。在部分(fen)省市相繼出現限(xian)電(dian)(dian)的形勢下(xia)(xia)(xia)，江(jiang)西(xi)電(dian)(dian)網克服惡劣天氣(qi)影響及全(quan)國(guo)性(xing)的電(dian)(dian)煤供應緊(jin)張等(deng)困難，未拉(la)閘(zha)限(xian)電(dian)(dian)。
據介(jie)紹(shao)，經(jing)濟高速增長、氣溫驟然下降是促使我省冬季用電負(fu)荷迅速攀升的主要原因。2008年1月以來，全省工業經(jing)濟繼續呈現(xian)持續快速增長勢頭，全網日(ri)最大用電負(fu)荷均達到700萬千瓦以上，電網保持高負(fu)荷運(yun)行狀態。
1月(yue)12日(ri)凌(ling)晨(chen)，來自貝(bei)加爾湖地區(qu)的強(qiang)冷(leng)空氣入侵(qin)江西(xi)，全(quan)省(sheng)出現明顯大風降溫天氣，局部(bu)地區(qu)出現雨雪(xue)冰凍(dong)天氣。因氣溫下降，取暖(nuan)負荷增長明顯，拉動(dong)全(quan)省(sheng)用(yong)電(dian)(dian)負荷屢創新高(gao)(gao)。1月(yue)14日(ri)11：30，全(quan)網(wang)最(zui)高(gao)(gao)用(yong)電(dian)(dian)負荷達到788.5萬(wan)(wan)千(qian)瓦，1月(yue)15日(ri)11：25，全(quan)網(wang)最(zui)高(gao)(gao)用(yong)電(dian)(dian)負荷沖至802.9萬(wan)(wan)千(qian)瓦，突破去年迎峰(feng)(feng)度夏800.2萬(wan)(wan)千(qian)瓦的峰(feng)(feng)值，當日(ri)用(yong)電(dian)(dian)量達1.53億千(qian)瓦時，用(yong)電(dian)(dian)負荷及日(ri)用(yong)電(dian)(dian)量雙(shuang)雙(shuang)創下歷史最(zui)高(gao)(gao)紀錄。15日(ri)，江西(xi)電(dian)(dian)網(wang)火(huo)電(dian)(dian)機組滿發輸(shu)送710萬(wan)(wan)千(qian)瓦電(dian)(dian)力(li)，水電(dian)(dian)頂(ding)峰(feng)(feng)90萬(wan)(wan)千(qian)瓦左右，并通過外購8萬(wan)(wan)千(qian)瓦電(dian)(dian)力(li)，確保了全(quan)省(sheng)電(dian)(dian)力(li)可靠(kao)供應。
記者從(cong)江西(xi)(xi)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)調度中心了解到，全省(sheng)冬(dong)季(ji)大(da)(da)負(fu)荷還將持續一(yi)段時(shi)期(qi)，受電(dian)(dian)(dian)(dian)煤供應(ying)緊張(zhang)、火電(dian)(dian)(dian)(dian)機組(zu)缺(que)陷、水(shui)電(dian)(dian)(dian)(dian)來(lai)水(shui)不(bu)足及(ji)惡劣天(tian)氣等(deng)因素(su)影響，江西(xi)(xi)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)迎峰度冬(dong)面臨嚴峻考(kao)驗(yan)。為此(ci)，公司(si)正(zheng)會同省(sheng)政(zheng)府有關部門積極(ji)采取措(cuo)施(shi)，最大(da)(da)努力(li)(li)以(yi)確保(bao)今年春(chun)節期(qi)間全省(sheng)電(dian)(dian)(dian)(dian)力(li)(li)可靠供應(ying)。一(yi)是(shi)配合(he)做好電(dian)(dian)(dian)(dian)煤協(xie)調工(gong)作，加大(da)(da)電(dian)(dian)(dian)(dian)煤調運(yun)(yun)(yun)力(li)(li)度，密(mi)切關注主力(li)(li)電(dian)(dian)(dian)(dian)廠(chang)電(dian)(dian)(dian)(dian)煤供應(ying)情況(kuang)，科(ke)學安排電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)調度運(yun)(yun)(yun)行(xing)方式；二是(shi)做好惡劣天(tian)氣下電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)運(yun)(yun)(yun)行(xing)設備的巡視和維護，制定電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)防大(da)(da)風抗(kang)冰災措(cuo)施(shi)，組(zu)織(zhi)力(li)(li)量及(ji)時(shi)整治(zhi)設備缺(que)陷、排除各(ge)種突發故障，確保(bao)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)安全穩定運(yun)(yun)(yun)行(xing)；三是(shi)積極(ji)增購外網(wang)(wang)(wang)(wang)電(dian)(dian)(dian)(dian)力(li)(li)以(yi)填(tian)補本省(sheng)電(dian)(dian)(dian)(dian)力(li)(li)供應(ying)缺(que)口，1月至(zhi)2月力(li)(li)爭外購50萬千瓦的電(dian)(dian)(dian)(dian)力(li)(li)緩(huan)解高峰時(shi)供電(dian)(dian)(dian)(dian)壓力(li)(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。
