據統(tong)計，截止到2007年11月(yue)2日，三峽電站歷年累計發電量突(tu)破(po)2000億(yi)千瓦時。這相當(dang)于少燃燒8000多萬噸(dun)標(biao)準煤。
三(san)峽(xia)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)共分(fen)左(zuo)(zuo)岸電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)、右岸電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)、右岸地下(xia)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)和電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)四(si)個電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)，分(fen)別設計安裝14臺(tai)(tai)70萬千(qian)瓦(wa)(wa)(wa)、12臺(tai)(tai)70萬千(qian)瓦(wa)(wa)(wa)、6臺(tai)(tai)70萬千(qian)瓦(wa)(wa)(wa)和2臺(tai)(tai)5萬千(qian)瓦(wa)(wa)(wa)水(shui)輪發電(dian)(dian)(dian)(dian)機(ji)(ji)組(zu)，總裝機(ji)(ji)容(rong)量達(da)(da)2250萬千(qian)瓦(wa)(wa)(wa)。其中(zhong)左(zuo)(zuo)岸電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)首臺(tai)(tai)機(ji)(ji)組(zu)于(yu)2003年7月(yue)(yue)10日正式并網(wang)發電(dian)(dian)(dian)(dian)，左(zuo)(zuo)岸電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)14臺(tai)(tai)機(ji)(ji)組(zu)于(yu)2005年9月(yue)(yue)全部投產發電(dian)(dian)(dian)(dian)；右岸電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)首臺(tai)(tai)機(ji)(ji)組(zu)于(yu)2007年6月(yue)(yue)11日正式并網(wang)發電(dian)(dian)(dian)(dian)，目前(qian)已有5臺(tai)(tai)機(ji)(ji)組(zu)投產發電(dian)(dian)(dian)(dian)；電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)2臺(tai)(tai)機(ji)(ji)組(zu)也(ye)于(yu)2007年2月(yue)(yue)全部投產發電(dian)(dian)(dian)(dian)。截至目前(qian)，三(san)峽(xia)電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)投產機(ji)(ji)組(zu)裝機(ji)(ji)容(rong)量累計達(da)(da)到1340萬千(qian)瓦(wa)(wa)(wa)，形成和鞏固了以三(san)峽(xia)為中(zhong)心的(de)(de)我(wo)國(guo)電(dian)(dian)(dian)(dian)網(wang)南(nan)北互聯、西電(dian)(dian)(dian)(dian)東(dong)送(song)的(de)(de)格局。
三峽電(dian)(dian)(dian)(dian)站(zhan)自2003年左岸電(dian)(dian)(dian)(dian)站(zhan)首批機組投產(chan)發(fa)電(dian)(dian)(dian)(dian)以來，歷年發(fa)電(dian)(dian)(dian)(dian)量分別(bie)為86億(yi)千瓦(wa)時、392億(yi)千瓦(wa)時、491億(yi)千瓦(wa)時、493億(yi)千瓦(wa)時和538億(yi)千瓦(wa)時（2007年前11個月發(fa)電(dian)(dian)(dian)(dian)量），送往華中電(dian)(dian)(dian)(dian)網(wang)、送華東電(dian)(dian)(dian)(dian)網(wang)和南方電(dian)(dian)(dian)(dian)網(wang)的(de)電(dian)(dian)(dian)(dian)量比例(li)分別(bie)為30.8%、43.5%和25.7%。三峽電(dian)(dian)(dian)(dian)站(zhan)發(fa)出的(de)強大、優質清潔(jie)電(dian)(dian)(dian)(dian)能有力地緩解了當前用電(dian)(dian)(dian)(dian)緊張的(de)局面，促進(jin)了環境改善(shan)。
