今年1月份(fen)，在電(dian)煤供應緊缺的情況下，江西(xi)電(dian)網(wang)充分發揮晉東南—南陽—荊門1000千伏(fu)特高壓等跨省區輸(shu)電(dian)工程遠(yuan)距離輸(shu)電(dian)優勢，在最(zui)高用電(dian)負荷連續三次創出(chu)歷史(shi)新高的情況下，保證了全省未拉閘(zha)限電(dian)和電(dian)網(wang)安全穩定運行。
1月份(fen)(fen)，受(shou)北方冷(leng)空氣(qi)影(ying)響，江(jiang)(jiang)西全省用電(dian)(dian)(dian)負荷迅速攀升(sheng)，電(dian)(dian)(dian)網(wang)統調最高(gao)(gao)用電(dian)(dian)(dian)負荷1月5至(zhi)7日三次創出(chu)新高(gao)(gao)。其時(shi)，江(jiang)(jiang)西各發電(dian)(dian)(dian)企業電(dian)(dian)(dian)煤(mei)庫(ku)(ku)存正出(chu)現前(qian)所未有的緊張(zhang)。據統計，1月份(fen)(fen)，江(jiang)(jiang)西電(dian)(dian)(dian)煤(mei)庫(ku)(ku)存最低時(shi)只有82萬(wan)噸(dun)，遠低于江(jiang)(jiang)西電(dian)(dian)(dian)網(wang)230萬(wan)噸(dun)的迎(ying)峰(feng)(feng)度(du)冬正常存煤(mei)要求。為保證(zheng)全省電(dian)(dian)(dian)力可(ke)靠供應，江(jiang)(jiang)西公司加大(da)跨區(qu)外購電(dian)(dian)(dian)力度(du)，充分(fen)發揮晉東南—南陽—荊門1000千伏特(te)高(gao)(gao)壓線路大(da)功率(lv)遠距離(li)輸(shu)(shu)電(dian)(dian)(dian)和靈寶(bao)、寶(bao)德等(deng)跨區(qu)輸(shu)(shu)電(dian)(dian)(dian)線路的優勢，積(ji)極強化跨省區(qu)輸(shu)(shu)電(dian)(dian)(dian)調度(du)。在1月份(fen)(fen)用電(dian)(dian)(dian)高(gao)(gao)峰(feng)(feng)時(shi)期(qi)，江(jiang)(jiang)西電(dian)(dian)(dian)網(wang)每(mei)天(tian)(tian)從省外輸(shu)(shu)入(ru)電(dian)(dian)(dian)力達110萬(wan)千瓦，確(que)保了江(jiang)(jiang)西電(dian)(dian)(dian)網(wang)未拉閘限電(dian)(dian)(dian)。特(te)高(gao)(gao)壓輸(shu)(shu)電(dian)(dian)(dian)線路入(ru)贛電(dian)(dian)(dian)力平均每(mei)天(tian)(tian)達60萬(wan)千瓦以(yi)上，占省外入(ru)贛電(dian)(dian)(dian)力的近50%。
據介紹，在2009年，特高壓電網工程(cheng)輸(shu)贛電量就達(da)10.52億千(qian)瓦時，電網變運煤為輸(shu)電，減(jian)少江西煤炭(tan)運力約58萬噸，減(jian)少省內二氧化碳排放150萬噸，減(jian)少二氧化硫排放7165噸。
