今年1月份(fen)，在電(dian)(dian)(dian)煤(mei)供應緊缺的情(qing)況(kuang)下(xia)，江(jiang)西電(dian)(dian)(dian)網充分(fen)發揮晉東南—南陽—荊門1000千伏特高壓等跨省(sheng)區(qu)輸(shu)(shu)電(dian)(dian)(dian)工程遠距離(li)輸(shu)(shu)電(dian)(dian)(dian)優勢，在最高用電(dian)(dian)(dian)負荷連續三次(ci)創出歷史新(xin)高的情(qing)況(kuang)下(xia)，保證了全省(sheng)未拉閘(zha)限(xian)電(dian)(dian)(dian)和電(dian)(dian)(dian)網安(an)全穩定運(yun)行。
1月(yue)份，受北方冷空氣影響，江(jiang)西(xi)(xi)全省(sheng)(sheng)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)負(fu)荷迅速攀升，電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)統(tong)調最高用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)負(fu)荷1月(yue)5至(zhi)7日三次創(chuang)出新高。其時(shi)，江(jiang)西(xi)(xi)各發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)企業電(dian)(dian)(dian)(dian)(dian)(dian)煤(mei)庫(ku)存正出現前所未(wei)有(you)(you)的(de)(de)緊張。據統(tong)計，1月(yue)份，江(jiang)西(xi)(xi)電(dian)(dian)(dian)(dian)(dian)(dian)煤(mei)庫(ku)存最低時(shi)只有(you)(you)82萬(wan)(wan)噸(dun)，遠低于江(jiang)西(xi)(xi)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)230萬(wan)(wan)噸(dun)的(de)(de)迎峰度(du)(du)冬正常存煤(mei)要求。為保證全省(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)力可靠供應，江(jiang)西(xi)(xi)公司(si)加大跨(kua)區外(wai)購電(dian)(dian)(dian)(dian)(dian)(dian)力度(du)(du)，充分(fen)發(fa)揮(hui)晉東南—南陽—荊門(men)1000千伏特(te)高壓線(xian)路大功率(lv)遠距離輸電(dian)(dian)(dian)(dian)(dian)(dian)和靈(ling)寶、寶德等(deng)跨(kua)區輸電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)路的(de)(de)優(you)勢，積(ji)極強化跨(kua)省(sheng)(sheng)區輸電(dian)(dian)(dian)(dian)(dian)(dian)調度(du)(du)。在(zai)1月(yue)份用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)高峰時(shi)期(qi)，江(jiang)西(xi)(xi)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)每(mei)天從(cong)省(sheng)(sheng)外(wai)輸入電(dian)(dian)(dian)(dian)(dian)(dian)力達110萬(wan)(wan)千瓦，確保了江(jiang)西(xi)(xi)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)未(wei)拉閘限電(dian)(dian)(dian)(dian)(dian)(dian)。特(te)高壓輸電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)路入贛(gan)電(dian)(dian)(dian)(dian)(dian)(dian)力平均(jun)每(mei)天達60萬(wan)(wan)千瓦以上，占省(sheng)(sheng)外(wai)入贛(gan)電(dian)(dian)(dian)(dian)(dian)(dian)力的(de)(de)近50%。
據(ju)介紹，在2009年，特高壓(ya)電網(wang)工程(cheng)輸(shu)贛電量就達10.52億千瓦時，電網(wang)變(bian)運煤為輸(shu)電，減(jian)少(shao)(shao)江西煤炭運力約58萬噸，減(jian)少(shao)(shao)省內(nei)二(er)氧(yang)化(hua)碳(tan)排放150萬噸，減(jian)少(shao)(shao)二(er)氧(yang)化(hua)硫(liu)排放7165噸。
