南(nan)(nan)(nan)方(fang)電(dian)(dian)網公司認真貫(guan)徹國家(jia)西(xi)部(bu)大開發(fa)戰略(lve)部(bu)署，積極實(shi)施西(xi)電(dian)(dian)東(dong)(dong)送。截至2015年10月(yue)25日，南(nan)(nan)(nan)方(fang)電(dian)(dian)網“十二五”期間累(lei)計送出云(yun)南(nan)(nan)(nan)電(dian)(dian)量(liang)突破了(le)3000億(yi)(yi)千瓦(wa)時，達(da)3024億(yi)(yi)千瓦(wa)時。自1993年、2013年云(yun)南(nan)(nan)(nan)先后向廣東(dong)(dong)、廣西(xi)送電(dian)(dian)開始，南(nan)(nan)(nan)方(fang)電(dian)(dian)網西(xi)電(dian)(dian)東(dong)(dong)送云(yun)南(nan)(nan)(nan)電(dian)(dian)量(liang)已累(lei)計達(da)4304億(yi)(yi)千瓦(wa)時，為南(nan)(nan)(nan)方(fang)區域(yu)東(dong)(dong)西(xi)部(bu)能源結構優化、經(jing)濟社(she)會協(xie)調發(fa)展發(fa)揮(hui)了(le)重要的作用。
云南(nan)省(sheng)是(shi)全國較早實(shi)施西電東送(song)工程的省(sheng)份(fen)之(zhi)一，在 2002年(nian)底(di)南(nan)方(fang)電網公司成立后(hou)發展速度進一步加快，尤其是(shi)“十(shi)二五(wu)”期間實(shi)現(xian)了跨(kua)越(yue)發展，送(song)電最(zui)高負荷達(da)1900萬千瓦，分別較1993年(nian)送(song)電之(zhi)初、“十(shi)一五(wu)”末增(zeng)長了76、2.5倍(bei)(bei)；最(zui)高年(nian)送(song)電量(liang)達(da)922億千瓦時（2015年(nian)預計），分別較1993年(nian)送(song)電之(zhi)初、“十(shi)一五(wu)”末增(zeng)長了37倍(bei)(bei)、2.9倍(bei)(bei)。
目前，南(nan)(nan)(nan)方電(dian)(dian)(dian)網在(zai)云南(nan)(nan)(nan)建成(cheng)了“四條直(zhi)流、四條交流”西(xi)(xi)電(dian)(dian)(dian)東送(song)主(zhu)通道，送(song)電(dian)(dian)(dian)規(gui)模占到南(nan)(nan)(nan)方電(dian)(dian)(dian)網西(xi)(xi)電(dian)(dian)(dian)東送(song)總(zong)規(gui)模的(de)50%以上；預計到“十三五”期間(jian)云南(nan)(nan)(nan)西(xi)(xi)電(dian)(dian)(dian)東送(song)將(jiang)形(xing)成(cheng)7條直(zhi)流主(zhu)通道，送(song)電(dian)(dian)(dian)規(gui)模占到南(nan)(nan)(nan)方電(dian)(dian)(dian)網西(xi)(xi)電(dian)(dian)(dian)東送(song)總(zong)規(gui)模的(de)65%，送(song)電(dian)(dian)(dian)總(zong)規(gui)模達(da)2950萬千瓦(wa)(wa)，年送(song)電(dian)(dian)(dian)量將(jiang)維(wei)持(chi)在(zai)1000億千瓦(wa)(wa)時(shi)以上。
