12月26日，由我國(guo)自主(zhu)設(she)計、自主(zhu)建(jian)設(she)的向家壩-上海(hai)±800千伏特(te)高(gao)(gao)壓(ya)直(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)示范(fan)工(gong)程(cheng)(cheng)全(quan)(quan)線升(sheng)(sheng)壓(ya)至直(zhi)(zhi)流(liu)(liu)800千伏，標(biao)志(zhi)著目前世(shi)(shi)界上輸(shu)送容量最(zui)大、送電(dian)(dian)(dian)(dian)距離最(zui)遠(yuan)、技(ji)術(shu)水平(ping)最(zui)先進、電(dian)(dian)(dian)(dian)壓(ya)等級最(zui)高(gao)(gao)的直(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)工(gong)程(cheng)(cheng)全(quan)(quan)線帶電(dian)(dian)(dian)(dian)成功(gong)。該工(gong)程(cheng)(cheng)額定電(dian)(dian)(dian)(dian)壓(ya)±800千伏、額定電(dian)(dian)(dian)(dian)流(liu)(liu)4000安培(pei)，輸(shu)送功(gong)率可達(da)700萬(wan)千瓦級，是引領(ling)世(shi)(shi)界直(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)技(ji)術(shu)發展的創新工(gong)程(cheng)(cheng)，在世(shi)(shi)界上率先實現(xian)特(te)高(gao)(gao)壓(ya)直(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)流(liu)(liu)雙提(ti)升(sheng)(sheng)、雙突破，代表世(shi)(shi)界直(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)技(ji)術(shu)的最(zui)高(gao)(gao)水平(ping)，也(ye)標(biao)志(zhi)著國(guo)家電(dian)(dian)(dian)(dian)網(wang)全(quan)(quan)面進入特(te)高(gao)(gao)壓(ya)交(jiao)直(zhi)(zhi)流(liu)(liu)混合電(dian)(dian)(dian)(dian)網(wang)時期(qi)。
該(gai)工程西起四(si)川向家壩(ba)復(fu)龍換流站(zhan)，東(dong)至上(shang)海(hai)奉賢換流站(zhan)，全長(chang)約1907公里，途經8個(ge)省(sheng)市(shi)，4次(ci)跨越長(chang)江，對于(yu)實現西南水電能(neng)源基(ji)地(di)大規模(mo)開發和(he)經濟高效送出，進一(yi)步(bu)促(cu)進我國清(qing)(qing)潔能(neng)源快速發展(zhan)，滿足東(dong)部地(di)區日(ri)益增長(chang)的負荷發展(zhan)需要，改善能(neng)源結構，促(cu)進節(jie)能(neng)減(jian)排(pai)，具有重要意(yi)義和(he)深遠影響(xiang)。通(tong)過(guo)(guo)該(gai)工程每年可(ke)向上(shang)海(hai)輸(shu)送四(si)川清(qing)(qing)潔水電350億千瓦時(shi)，相當于(yu)目前上(shang)海(hai)市(shi)全年用電量的三分(fen)之一(yi)，比在上(shang)海(hai)直接建設(she)火力發電廠，每年可(ke)節(jie)省(sheng)原煤(mei)1600萬噸，減(jian)排(pai)二(er)氧化碳超(chao)過(guo)(guo)2600萬噸，節(jie)能(neng)減(jian)排(pai)意(yi)義重大。
