今年1月份，在(zai)電(dian)煤供應緊缺的情(qing)況(kuang)下，江西(xi)電(dian)網充分發(fa)揮晉(jin)東(dong)南—南陽—荊門(men)1000千伏(fu)特高(gao)(gao)壓等跨省區輸電(dian)工程遠距離輸電(dian)優勢，在(zai)最高(gao)(gao)用電(dian)負荷連(lian)續三次創出歷史新高(gao)(gao)的情(qing)況(kuang)下，保證(zheng)了全省未拉閘限電(dian)和電(dian)網安(an)全穩定(ding)運行。
1月(yue)份，受北(bei)方冷空氣影響(xiang)，江(jiang)(jiang)西(xi)全(quan)省(sheng)用電(dian)(dian)(dian)負荷(he)迅速攀(pan)升，電(dian)(dian)(dian)網(wang)統調(diao)最高用電(dian)(dian)(dian)負荷(he)1月(yue)5至7日(ri)三(san)次創出新高。其時(shi)(shi)，江(jiang)(jiang)西(xi)各(ge)發(fa)電(dian)(dian)(dian)企(qi)業電(dian)(dian)(dian)煤(mei)庫存(cun)正出現(xian)前所未有的緊(jin)張。據統計，1月(yue)份，江(jiang)(jiang)西(xi)電(dian)(dian)(dian)煤(mei)庫存(cun)最低(di)時(shi)(shi)只有82萬噸(dun)，遠低(di)于江(jiang)(jiang)西(xi)電(dian)(dian)(dian)網(wang)230萬噸(dun)的迎峰度冬(dong)正常存(cun)煤(mei)要求。為保證全(quan)省(sheng)電(dian)(dian)(dian)力(li)可(ke)靠(kao)供應(ying)，江(jiang)(jiang)西(xi)公司(si)加大跨(kua)區(qu)外(wai)(wai)購(gou)電(dian)(dian)(dian)力(li)度，充分(fen)發(fa)揮晉東南(nan)(nan)—南(nan)(nan)陽—荊門1000千(qian)伏(fu)特高壓(ya)線(xian)路大功(gong)率遠距離(li)輸電(dian)(dian)(dian)和靈寶、寶德(de)等跨(kua)區(qu)輸電(dian)(dian)(dian)線(xian)路的優勢，積(ji)極強化跨(kua)省(sheng)區(qu)輸電(dian)(dian)(dian)調(diao)度。在1月(yue)份用電(dian)(dian)(dian)高峰時(shi)(shi)期(qi)，江(jiang)(jiang)西(xi)電(dian)(dian)(dian)網(wang)每天(tian)從省(sheng)外(wai)(wai)輸入電(dian)(dian)(dian)力(li)達(da)110萬千(qian)瓦，確保了江(jiang)(jiang)西(xi)電(dian)(dian)(dian)網(wang)未拉閘限電(dian)(dian)(dian)。特高壓(ya)輸電(dian)(dian)(dian)線(xian)路入贛電(dian)(dian)(dian)力(li)平均每天(tian)達(da)60萬千(qian)瓦以上(shang)，占省(sheng)外(wai)(wai)入贛電(dian)(dian)(dian)力(li)的近50%。
據介紹，在2009年(nian)，特高壓電(dian)(dian)網工程(cheng)輸(shu)贛電(dian)(dian)量就達(da)10.52億(yi)千瓦(wa)時，電(dian)(dian)網變運(yun)煤為輸(shu)電(dian)(dian)，減少(shao)江西煤炭運(yun)力(li)約58萬噸(dun)，減少(shao)省內二(er)氧化碳排放150萬噸(dun)，減少(shao)二(er)氧化硫排放7165噸(dun)。
