今年(nian)1月份，在(zai)電煤供應緊缺(que)的情況(kuang)下(xia)，江西電網(wang)充分發揮(hui)晉東(dong)南—南陽—荊門1000千伏(fu)特高壓等跨省(sheng)區輸電工程(cheng)遠距離輸電優勢，在(zai)最(zui)高用電負荷連續三次創出歷史新高的情況(kuang)下(xia)，保證了全(quan)省(sheng)未拉閘限電和電網(wang)安全(quan)穩定運行。
1月(yue)(yue)份，受北方冷空(kong)氣影(ying)響，江(jiang)(jiang)(jiang)西(xi)全(quan)省(sheng)(sheng)(sheng)用電(dian)(dian)(dian)(dian)負荷迅速攀升，電(dian)(dian)(dian)(dian)網統(tong)調(diao)最(zui)高(gao)用電(dian)(dian)(dian)(dian)負荷1月(yue)(yue)5至(zhi)7日(ri)三(san)次創出新高(gao)。其時(shi)，江(jiang)(jiang)(jiang)西(xi)各發電(dian)(dian)(dian)(dian)企業電(dian)(dian)(dian)(dian)煤(mei)庫(ku)存(cun)正出現前(qian)所未有的(de)緊張。據(ju)統(tong)計，1月(yue)(yue)份，江(jiang)(jiang)(jiang)西(xi)電(dian)(dian)(dian)(dian)煤(mei)庫(ku)存(cun)最(zui)低時(shi)只有82萬(wan)噸，遠低于江(jiang)(jiang)(jiang)西(xi)電(dian)(dian)(dian)(dian)網230萬(wan)噸的(de)迎(ying)峰度冬正常存(cun)煤(mei)要求。為保證全(quan)省(sheng)(sheng)(sheng)電(dian)(dian)(dian)(dian)力(li)可靠(kao)供應，江(jiang)(jiang)(jiang)西(xi)公(gong)司加(jia)大跨區(qu)外購電(dian)(dian)(dian)(dian)力(li)度，充分(fen)發揮晉東南—南陽—荊門(men)1000千伏(fu)特高(gao)壓線路大功率(lv)遠距離輸(shu)電(dian)(dian)(dian)(dian)和靈(ling)寶、寶德等(deng)跨區(qu)輸(shu)電(dian)(dian)(dian)(dian)線路的(de)優勢，積極強化(hua)跨省(sheng)(sheng)(sheng)區(qu)輸(shu)電(dian)(dian)(dian)(dian)調(diao)度。在(zai)1月(yue)(yue)份用電(dian)(dian)(dian)(dian)高(gao)峰時(shi)期，江(jiang)(jiang)(jiang)西(xi)電(dian)(dian)(dian)(dian)網每(mei)天從省(sheng)(sheng)(sheng)外輸(shu)入電(dian)(dian)(dian)(dian)力(li)達(da)110萬(wan)千瓦，確保了江(jiang)(jiang)(jiang)西(xi)電(dian)(dian)(dian)(dian)網未拉(la)閘限電(dian)(dian)(dian)(dian)。特高(gao)壓輸(shu)電(dian)(dian)(dian)(dian)線路入贛(gan)電(dian)(dian)(dian)(dian)力(li)平均每(mei)天達(da)60萬(wan)千瓦以上，占(zhan)省(sheng)(sheng)(sheng)外入贛(gan)電(dian)(dian)(dian)(dian)力(li)的(de)近50%。
據介(jie)紹(shao)，在2009年，特高壓電(dian)網工程(cheng)輸贛(gan)電(dian)量(liang)就達10.52億千瓦(wa)時，電(dian)網變運(yun)煤為輸電(dian)，減少江西(xi)煤炭運(yun)力(li)約58萬(wan)噸，減少省內二氧化碳(tan)排(pai)放(fang)150萬(wan)噸，減少二氧化硫排(pai)放(fang)7165噸。
