近日(ri)，在(zai)云南(nan)昆明召開(kai)的(de)2021年西電東送省(sheng)間協(xie)商會暨南(nan)方區(qu)域(yu)跨區(qu)跨省(sheng)“六簽(qian)”工作推進會上，參(can)會各方綜合經(jing)濟(ji)形勢、氣候(hou)預測、疫(yi)情影響、用(yong)電結構及今年用(yong)電增長(chang)等情況，對下(xia)一(yi)階段的(de)電力供需形勢進行了深入分(fen)析。

會上，南方電(dian)(dian)網公司(si)通(tong)報(bao)了(le)南方區(qu)(qu)域2020年(nian)(nian)(nian)(nian)電(dian)(dian)力供應(ying)、電(dian)(dian)網運行及西(xi)電(dian)(dian)東(dong)(dong)送(song)(song)情況，分析(xi)了(le)2021年(nian)(nian)(nian)(nian)電(dian)(dian)力供需形勢，介紹了(le)2021年(nian)(nian)(nian)(nian)西(xi)電(dian)(dian)東(dong)(dong)送(song)(song)優先計(ji)劃(hua)安排建議。通(tong)報(bao)顯示，今年(nian)(nian)(nian)(nian)1—10月，南方電(dian)(dian)網統調最大負(fu)荷2億千(qian)瓦(wa)，同比增(zeng)長(chang)7%，6月以(yi)來七創新高；南方五(wu)省區(qu)(qu)全(quan)社會用(yong)電(dian)(dian)量10708億千(qian)瓦(wa)時，同比增(zeng)長(chang)3.8%；累計(ji)完成西(xi)電(dian)(dian)東(dong)(dong)送(song)(song)電(dian)(dian)量1980億千(qian)瓦(wa)時，超年(nian)(nian)(nian)(nian)度(du)協議計(ji)劃(hua)281億千(qian)瓦(wa)時。
