今年以(yi)來(lai)，面對用電(dian)需(xu)求不旺、汛前水位消(xiao)落困(kun)難的嚴峻形(xing)勢(shi)，南方電(dian)網公司堅(jian)決(jue)貫(guan)徹執行國家節能減排(pai)政策(ce)，大力(li)實施節能發電(dian)調度(du)。1－4月，全網統調水電(dian)發電(dian)量373億(yi)千瓦時(shi)，同比增長53.3%，相當于(yu)節約標(biao)煤416萬噸，減少(shao)二氧(yang)化(hua)硫排(pai)放10萬噸，節能減排(pai)效果顯著。
受(shou)2008年(nian)11月特大(da)秋汛(xun)影響，2009年(nian)初南(nan)方電(dian)(dian)(dian)(dian)網供電(dian)(dian)(dian)(dian)區域(yu)內各(ge)大(da)水(shui)(shui)(shui)庫(ku)水(shui)(shui)(shui)位(wei)明顯偏高(gao)，全(quan)網水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)蓄能達220億千瓦時，是2008年(nian)初的(de)(de)2倍多。南(nan)方電(dian)(dian)(dian)(dian)網公(gong)司超前組(zu)織制(zhi)定紅水(shui)(shui)(shui)河、烏江、瀾滄江三大(da)流(liu)域(yu)梯級(ji)水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)優化(hua)(hua)調(diao)(diao)(diao)度(du)方案，明確(que)汛(xun)前各(ge)大(da)水(shui)(shui)(shui)庫(ku)的(de)(de)水(shui)(shui)(shui)位(wei)消落目(mu)標(biao)。加強全(quan)網統籌協調(diao)(diao)(diao)，實施(shi)水(shui)(shui)(shui)火電(dian)(dian)(dian)(dian)以及(ji)跨流(liu)域(yu)水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)聯(lian)合優化(hua)(hua)調(diao)(diao)(diao)度(du)，精心安排設備檢修(xiu)和火電(dian)(dian)(dian)(dian)開機(ji)方式(shi)。發揮大(da)電(dian)(dian)(dian)(dian)網資源(yuan)優化(hua)(hua)平臺(tai)作用，深化(hua)(hua)快速(su)靈活調(diao)(diao)(diao)度(du)，盡最大(da)能力吸納水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)。通過努(nu)力，全(quan)網各(ge)大(da)水(shui)(shui)(shui)庫(ku)水(shui)(shui)(shui)位(wei)基(ji)本消落至控制(zhi)目(mu)標(biao)以下，降低了汛(xun)期大(da)量棄水(shui)(shui)(shui)的(de)(de)風險(xian)，最大(da)限度(du)地(di)利用水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)這一清潔、優質的(de)(de)可再生(sheng)能源(yuan)。
