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8月30日開(kai)始(shi)，重(zhong)慶地區(qu)最(zui)高(gao)氣(qi)溫升至(zhi)(zhi)39攝氏度以上(shang)，9月3日后(hou)更是超過(guo)40攝氏度。受持續高(gao)溫影響(xiang)，重(zhong)慶電(dian)(dian)(dian)網(wang)(wang)最(zui)大用(yong)電(dian)(dian)(dian)負荷從8月28日的(de)880萬千瓦直線上(shang)升至(zhi)(zhi)9月4日之后(hou)的(de)1100萬千瓦，日均用(yong)電(dian)(dian)(dian)量達2.18億千瓦時(shi)。重(zhong)慶電(dian)(dian)(dian)網(wang)(wang)經受迎峰(feng)度夏期的(de)用(yong)電(dian)(dian)(dian)高(gao)峰(feng)考驗后(hou)，網(wang)(wang)內發電(dian)(dian)(dian)機組已顯(xian)疲態，主力(li)(li)水(shui)電(dian)(dian)(dian)廠彭水(shui)、江口電(dian)(dian)(dian)廠水(shui)庫水(shui)位嚴重(zhong)偏低。電(dian)(dian)(dian)網(wang)(wang)又(you)一次面臨拉閘限電(dian)(dian)(dian)的(de)風險。在(zai)華中全網(wang)(wang)電(dian)(dian)(dian)力(li)(li)供(gong)應(ying)極為短缺(que)的(de)情況下，華中公司精心調(diao)度，實時(shi)有(you)效地利用(yong)網(wang)(wang)內電(dian)(dian)(dian)力(li)(li)資源，加大對重(zhong)慶的(de)支援力(li)(li)度，有(you)力(li)(li)緩解了重(zhong)慶電(dian)(dian)(dian)網(wang)(wang)的(de)用(yong)電(dian)(dian)(dian)緊張，確保了重(zhong)慶在(zai)本輪用(yong)電(dian)(dian)(dian)高(gao)峰(feng)中沒(mei)有(you)拉閘限電(dian)(dian)(dian)。
