　　據統(tong)計，截止(zhi)到2007年11月2日(ri)，三峽(xia)電站歷年累計發電量突破(po)2000億(yi)千瓦時。這(zhe)相當于(yu)少(shao)燃燒8000多(duo)萬噸標(biao)準煤。

　　三峽電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)共(gong)分左岸(an)(an)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)、右(you)岸(an)(an)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)、右(you)岸(an)(an)地下電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)和電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)四個電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)，分別設計安裝14臺(tai)70萬(wan)(wan)(wan)千(qian)瓦(wa)(wa)(wa)(wa)、12臺(tai)70萬(wan)(wan)(wan)千(qian)瓦(wa)(wa)(wa)(wa)、6臺(tai)70萬(wan)(wan)(wan)千(qian)瓦(wa)(wa)(wa)(wa)和2臺(tai)5萬(wan)(wan)(wan)千(qian)瓦(wa)(wa)(wa)(wa)水(shui)輪發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)組(zu)(zu)，總裝機(ji)(ji)(ji)(ji)容量(liang)達2250萬(wan)(wan)(wan)千(qian)瓦(wa)(wa)(wa)(wa)。其中左岸(an)(an)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)首(shou)臺(tai)機(ji)(ji)(ji)(ji)組(zu)(zu)于2003年(nian)7月(yue)(yue)10日正式并網(wang)(wang)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)，左岸(an)(an)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)14臺(tai)機(ji)(ji)(ji)(ji)組(zu)(zu)于2005年(nian)9月(yue)(yue)全(quan)部(bu)(bu)投(tou)產發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)；右(you)岸(an)(an)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)首(shou)臺(tai)機(ji)(ji)(ji)(ji)組(zu)(zu)于2007年(nian)6月(yue)(yue)11日正式并網(wang)(wang)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)，目前(qian)(qian)已有5臺(tai)機(ji)(ji)(ji)(ji)組(zu)(zu)投(tou)產發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)；電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)2臺(tai)機(ji)(ji)(ji)(ji)組(zu)(zu)也(ye)于2007年(nian)2月(yue)(yue)全(quan)部(bu)(bu)投(tou)產發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)。截(jie)至目前(qian)(qian)，三峽電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)投(tou)產機(ji)(ji)(ji)(ji)組(zu)(zu)裝機(ji)(ji)(ji)(ji)容量(liang)累計達到1340萬(wan)(wan)(wan)千(qian)瓦(wa)(wa)(wa)(wa)，形成和鞏固了(le)以三峽為中心(xin)的(de)(de)我(wo)國電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)南北(bei)互(hu)聯、西(xi)電(dian)(dian)(dian)(dian)(dian)(dian)東送(song)的(de)(de)格局。

　　三峽電(dian)(dian)站(zhan)自2003年左岸(an)電(dian)(dian)站(zhan)首批(pi)機組投產發(fa)電(dian)(dian)以來，歷年發(fa)電(dian)(dian)量分(fen)別為86億(yi)千(qian)瓦(wa)時(shi)、392億(yi)千(qian)瓦(wa)時(shi)、491億(yi)千(qian)瓦(wa)時(shi)、493億(yi)千(qian)瓦(wa)時(shi)和538億(yi)千(qian)瓦(wa)時(shi)（2007年前(qian)11個月發(fa)電(dian)(dian)量），送往華(hua)中電(dian)(dian)網、送華(hua)東電(dian)(dian)網和南方(fang)電(dian)(dian)網的電(dian)(dian)量比例分(fen)別為30.8%、43.5%和25.7%。三峽電(dian)(dian)站(zhan)發(fa)出的強大、優質清潔(jie)電(dian)(dian)能有力地緩解了(le)(le)當前(qian)用(yong)電(dian)(dian)緊張的局面，促進了(le)(le)環境改善(shan)。
