據統計，截(jie)止到2007年11月2日(ri)，三峽電站歷年累計發電量(liang)突破2000億千瓦(wa)時。這相當于少燃(ran)燒8000多萬噸標(biao)準煤。
三(san)(san)峽電(dian)(dian)站(zhan)(zhan)(zhan)共分(fen)左岸(an)電(dian)(dian)站(zhan)(zhan)(zhan)、右(you)岸(an)電(dian)(dian)站(zhan)(zhan)(zhan)、右(you)岸(an)地下電(dian)(dian)站(zhan)(zhan)(zhan)和(he)電(dian)(dian)源(yuan)電(dian)(dian)站(zhan)(zhan)(zhan)四個電(dian)(dian)站(zhan)(zhan)(zhan)，分(fen)別(bie)設計安裝(zhuang)(zhuang)14臺(tai)(tai)(tai)70萬(wan)千(qian)瓦(wa)、12臺(tai)(tai)(tai)70萬(wan)千(qian)瓦(wa)、6臺(tai)(tai)(tai)70萬(wan)千(qian)瓦(wa)和(he)2臺(tai)(tai)(tai)5萬(wan)千(qian)瓦(wa)水輪發電(dian)(dian)機(ji)組(zu)(zu)(zu)，總裝(zhuang)(zhuang)機(ji)容量(liang)達2250萬(wan)千(qian)瓦(wa)。其中(zhong)(zhong)左岸(an)電(dian)(dian)站(zhan)(zhan)(zhan)首(shou)臺(tai)(tai)(tai)機(ji)組(zu)(zu)(zu)于2003年(nian)(nian)(nian)7月(yue)10日正(zheng)式(shi)并網(wang)發電(dian)(dian)，左岸(an)電(dian)(dian)站(zhan)(zhan)(zhan)14臺(tai)(tai)(tai)機(ji)組(zu)(zu)(zu)于2005年(nian)(nian)(nian)9月(yue)全(quan)部投產發電(dian)(dian)；右(you)岸(an)電(dian)(dian)站(zhan)(zhan)(zhan)首(shou)臺(tai)(tai)(tai)機(ji)組(zu)(zu)(zu)于2007年(nian)(nian)(nian)6月(yue)11日正(zheng)式(shi)并網(wang)發電(dian)(dian)，目前已有(you)5臺(tai)(tai)(tai)機(ji)組(zu)(zu)(zu)投產發電(dian)(dian)；電(dian)(dian)源(yuan)電(dian)(dian)站(zhan)(zhan)(zhan)2臺(tai)(tai)(tai)機(ji)組(zu)(zu)(zu)也于2007年(nian)(nian)(nian)2月(yue)全(quan)部投產發電(dian)(dian)。截至目前，三(san)(san)峽電(dian)(dian)站(zhan)(zhan)(zhan)投產機(ji)組(zu)(zu)(zu)裝(zhuang)(zhuang)機(ji)容量(liang)累計達到1340萬(wan)千(qian)瓦(wa)，形成和(he)鞏固了以三(san)(san)峽為中(zhong)(zhong)心的(de)我(wo)國(guo)電(dian)(dian)網(wang)南北互聯、西(xi)電(dian)(dian)東送的(de)格局(ju)。
三(san)峽(xia)電(dian)(dian)站自2003年(nian)左岸電(dian)(dian)站首批機組投產發電(dian)(dian)以來，歷年(nian)發電(dian)(dian)量(liang)分別為86億(yi)千瓦(wa)時(shi)、392億(yi)千瓦(wa)時(shi)、491億(yi)千瓦(wa)時(shi)、493億(yi)千瓦(wa)時(shi)和538億(yi)千瓦(wa)時(shi)（2007年(nian)前11個(ge)月發電(dian)(dian)量(liang)），送往(wang)華中電(dian)(dian)網、送華東電(dian)(dian)網和南方電(dian)(dian)網的(de)(de)電(dian)(dian)量(liang)比例(li)分別為30.8%、43.5%和25.7%。三(san)峽(xia)電(dian)(dian)站發出的(de)(de)強大、優質清潔電(dian)(dian)能有(you)力(li)地緩解了(le)當前用(yong)電(dian)(dian)緊(jin)張的(de)(de)局面，促(cu)進了(le)環境改善。
