自1993年、2013年云(yun)南(nan)(nan)先(xian)后向廣東(dong)(dong)、廣西(xi)送(song)電(dian)(dian)開(kai)始，截至2016年3月7日(ri)，云(yun)南(nan)(nan)省西(xi)電(dian)(dian)東(dong)(dong)送(song)電(dian)(dian)量累計突破4500億千(qian)瓦時，達(da)4561億千(qian)瓦時。預計2016年最高送(song)電(dian)(dian)量將(jiang)達(da)935億千(qian)瓦時，是(shi)西(xi)電(dian)(dian)東(dong)(dong)送(song)實施(shi)之初的170倍，為(wei)南(nan)(nan)方區域東(dong)(dong)西(xi)部能源結構優化(hua)、經濟(ji)社(she)會(hui)協調發(fa)(fa)展發(fa)(fa)揮了(le)重(zhong)要的作用。
云(yun)南省是(shi)全國較早實(shi)施西電(dian)(dian)(dian)東送(song)(song)工程的省份之(zhi)一(yi)，在 2002年(nian)底(di)南方電(dian)(dian)(dian)網公司成立后發展速度進一(yi)步(bu)加快，尤(you)其是(shi)“十(shi)二五”期間(jian)實(shi)現了跨越發展，送(song)(song)電(dian)(dian)(dian)最(zui)高負(fu)荷(he)達1925萬(wan)千瓦，分別是(shi)1993年(nian)送(song)(song)電(dian)(dian)(dian)之(zhi)初、“十(shi)一(yi)五”末(mo)的77、2.5倍；最(zui)高年(nian)送(song)(song)電(dian)(dian)(dian)量達945.8億千瓦時(shi)，分別是(shi)1993年(nian)送(song)(song)電(dian)(dian)(dian)之(zhi)初、“十(shi)一(yi)五”末(mo)的172倍、2.9倍。
目前，南(nan)(nan)(nan)(nan)方電(dian)(dian)(dian)網(wang)公司已在云(yun)(yun)南(nan)(nan)(nan)(nan)建成了“四條(tiao)直(zhi)(zhi)流(liu)、五條(tiao)交流(liu)”西(xi)(xi)(xi)電(dian)(dian)(dian)東(dong)(dong)送主(zhu)通(tong)(tong)(tong)道。2016年汛期，隨著云(yun)(yun)南(nan)(nan)(nan)(nan)金沙江中游(you)電(dian)(dian)(dian)站送電(dian)(dian)(dian)廣西(xi)(xi)(xi)直(zhi)(zhi)流(liu)輸電(dian)(dian)(dian)工(gong)程(cheng)、永仁至富寧±500千(qian)(qian)伏直(zhi)(zhi)流(liu)輸變電(dian)(dian)(dian)工(gong)程(cheng)、魯西(xi)(xi)(xi)背靠背直(zhi)(zhi)流(liu)異步聯網(wang)工(gong)程(cheng)的投產，云(yun)(yun)南(nan)(nan)(nan)(nan)電(dian)(dian)(dian)網(wang)將實現(xian)與南(nan)(nan)(nan)(nan)方電(dian)(dian)(dian)網(wang)主(zhu)網(wang)異步聯網(wang)運行，云(yun)(yun)南(nan)(nan)(nan)(nan)將形(xing)成7條(tiao)直(zhi)(zhi)流(liu)主(zhu)通(tong)(tong)(tong)道，西(xi)(xi)(xi)電(dian)(dian)(dian)東(dong)(dong)送能力(li)將提升(sheng)至2455萬千(qian)(qian)瓦。“十三(san)五”期間，隨著滇(dian)西(xi)(xi)(xi)北送電(dian)(dian)(dian)廣東(dong)(dong)±800千(qian)(qian)伏特高壓直(zhi)(zhi)流(liu)工(gong)程(cheng)的投運，云(yun)(yun)南(nan)(nan)(nan)(nan)西(xi)(xi)(xi)電(dian)(dian)(dian)東(dong)(dong)送將形(xing)成8條(tiao)直(zhi)(zhi)流(liu)主(zhu)通(tong)(tong)(tong)道，送電(dian)(dian)(dian)總規模將達2950萬千(qian)(qian)瓦，年送電(dian)(dian)(dian)量將維持在1000億千(qian)(qian)瓦時以(yi)上。
