自(zi)1993年、2013年云南先后向廣(guang)(guang)東(dong)、廣(guang)(guang)西送電開始，截至2016年3月7日，云南省西電東(dong)送電量累計突破4500億(yi)千瓦時，達4561億(yi)千瓦時。預(yu)計2016年最高(gao)送電量將達935億(yi)千瓦時，是西電東(dong)送實(shi)施之初的170倍，為南方(fang)區域東(dong)西部能(neng)源結構(gou)優(you)化(hua)、經濟(ji)社會協調發展發揮(hui)了重要的作用。
云(yun)南(nan)省是(shi)全國較早實施西電東送工程的省份之(zhi)(zhi)一，在(zai) 2002年底(di)南(nan)方電網公司成立后發(fa)展(zhan)(zhan)速度(du)進一步加快，尤其(qi)是(shi)“十(shi)(shi)二五(wu)”期間實現了跨越發(fa)展(zhan)(zhan)，送電最高負荷(he)達(da)1925萬千(qian)(qian)瓦，分別是(shi)1993年送電之(zhi)(zhi)初、“十(shi)(shi)一五(wu)”末(mo)的77、2.5倍(bei)；最高年送電量達(da)945.8億(yi)千(qian)(qian)瓦時，分別是(shi)1993年送電之(zhi)(zhi)初、“十(shi)(shi)一五(wu)”末(mo)的172倍(bei)、2.9倍(bei)。
目前(qian)，南方電(dian)(dian)網(wang)(wang)公司已在云(yun)(yun)南建(jian)成(cheng)了“四條直流、五條交(jiao)流”西(xi)電(dian)(dian)東送(song)(song)(song)主通(tong)道。2016年(nian)汛期(qi)，隨著(zhu)云(yun)(yun)南金沙江中游(you)電(dian)(dian)站送(song)(song)(song)電(dian)(dian)廣(guang)西(xi)直流輸電(dian)(dian)工程、永仁至富寧±500千(qian)伏直流輸變(bian)電(dian)(dian)工程、魯西(xi)背靠背直流異步聯(lian)(lian)網(wang)(wang)工程的(de)投產，云(yun)(yun)南電(dian)(dian)網(wang)(wang)將實現與南方電(dian)(dian)網(wang)(wang)主網(wang)(wang)異步聯(lian)(lian)網(wang)(wang)運(yun)(yun)行(xing)，云(yun)(yun)南將形(xing)成(cheng)7條直流主通(tong)道，西(xi)電(dian)(dian)東送(song)(song)(song)能力將提升至2455萬(wan)千(qian)瓦(wa)。“十三五”期(qi)間，隨著(zhu)滇西(xi)北送(song)(song)(song)電(dian)(dian)廣(guang)東±800千(qian)伏特高壓直流工程的(de)投運(yun)(yun)，云(yun)(yun)南西(xi)電(dian)(dian)東送(song)(song)(song)將形(xing)成(cheng)8條直流主通(tong)道，送(song)(song)(song)電(dian)(dian)總規模(mo)將達2950萬(wan)千(qian)瓦(wa)，年(nian)送(song)(song)(song)電(dian)(dian)量(liang)將維(wei)持在1000億千(qian)瓦(wa)時以上。
