9月初，華中電網迎峰度夏保電接近尾聲，但“秋老虎”發威使重慶電網出現新一輪用電高峰。華中電網有限公司充分發揮大區電網互聯的優勢，加大力度支援重慶，截至9月6日共支援重慶電量3420萬千瓦時，最大電力80萬千瓦。
從(cong)8月30日開始，重慶地區最(zui)高(gao)氣溫升(sheng)至39攝氏度(du)(du)以上，9月3日后更是超過40攝氏度(du)(du)。受持續高(gao)溫影響，重慶電(dian)(dian)(dian)(dian)網最(zui)大(da)用(yong)電(dian)(dian)(dian)(dian)負荷(he)從(cong)8月28日的880萬(wan)千(qian)瓦(wa)直線(xian)上升(sheng)至9月4日之后的1100萬(wan)千(qian)瓦(wa)，日均(jun)用(yong)電(dian)(dian)(dian)(dian)量達2.18億千(qian)瓦(wa)時(shi)。重慶電(dian)(dian)(dian)(dian)網經受迎峰(feng)度(du)(du)夏期的用(yong)電(dian)(dian)(dian)(dian)高(gao)峰(feng)考驗后，網內發電(dian)(dian)(dian)(dian)機組已(yi)顯疲(pi)態，主力(li)(li)水電(dian)(dian)(dian)(dian)廠(chang)彭水、江口電(dian)(dian)(dian)(dian)廠(chang)水庫水位嚴(yan)重偏低。電(dian)(dian)(dian)(dian)網又(you)一次面臨(lin)拉(la)閘限電(dian)(dian)(dian)(dian)的風(feng)險。在華(hua)(hua)中全網電(dian)(dian)(dian)(dian)力(li)(li)供應極為短缺(que)的情況下，華(hua)(hua)中公司精(jing)心調(diao)度(du)(du)，實時(shi)有(you)效地利用(yong)網內電(dian)(dian)(dian)(dian)力(li)(li)資源，加(jia)大(da)對重慶的支援(yuan)力(li)(li)度(du)(du)，有(you)力(li)(li)緩解了重慶電(dian)(dian)(dian)(dian)網的用(yong)電(dian)(dian)(dian)(dian)緊張，確(que)保(bao)了重慶在本輪用(yong)電(dian)(dian)(dian)(dian)高(gao)峰(feng)中沒有(you)拉(la)閘限電(dian)(dian)(dian)(dian)。
