近期，受經濟回暖以及持續高溫天氣等因素影響，南方地區用電需求不斷增長，電網負荷節節攀升。9月8日，南方電網統調負荷今年第8次創歷史新高，達9560萬千瓦，比去年最高負荷增長7.9%。同日，廣西電網統調負荷第14次創新高，達1169萬千瓦，比去年最高負荷增長16.2%；貴州電網統調負荷第8次創新高，達1139萬千瓦，比去年最高負荷增長8.9%。
日前，南方電(dian)(dian)(dian)網(wang)公司正按(an)照2009年(nian)迎峰度夏調度運(yun)行方案(an)全力(li)做好保供電(dian)(dian)(dian)各項工作。加強發電(dian)(dian)(dian)側和需求側管(guan)理(li)，快(kuai)速靈活調度，確保了電(dian)(dian)(dian)網(wang)安全“可控(kong)、在控(kong)”，在負荷連(lian)續攀升之際保障了電(dian)(dian)(dian)力(li)有序供應。截至9月(yue)8日，主網(wang)未發生穩(wen)定破壞、大面積停電(dian)(dian)(dian)事(shi)故及功(gong)率(lv)(lv)振(zhen)蕩事(shi)件，主要運(yun)行指標保持(chi)較好水平，全網(wang)500千(qian)伏平均(jun)電(dian)(dian)(dian)壓合(he)格率(lv)(lv)同(tong)(tong)(tong)比提高0.0414個百分點，±0.1Hz頻率(lv)(lv)越限時(shi)間同(tong)(tong)(tong)比大幅減(jian)少1034秒(miao)，220千(qian)伏及以上系統故障快(kuai)速切除率(lv)(lv)100%。全網(wang)統調發受電(dian)(dian)(dian)量3767億千(qian)瓦時(shi)，同(tong)(tong)(tong)比增長2.1%，單月(yue)同(tong)(tong)(tong)比由1月(yue)份的(de)-16.6%提高到8月(yue)份的(de)12.8%，呈逐步(bu)回(hui)升態勢；水電(dian)(dian)(dian)優(you)化(hua)調度成效顯著(zhu)，全網(wang)水電(dian)(dian)(dian)發電(dian)(dian)(dian)量1031億千(qian)瓦時(shi)，同(tong)(tong)(tong)比增長17.2%；西電(dian)(dian)(dian)送廣(guang)東電(dian)(dian)(dian)量743億千(qian)瓦時(shi)，同(tong)(tong)(tong)比增長27.2%。
