據統計，截止到2007年11月2日，三峽(xia)電(dian)站(zhan)歷年累計發電(dian)量(liang)突破2000億千瓦時。這相(xiang)當于少燃燒8000多萬噸標準煤(mei)。
三(san)峽電(dian)(dian)(dian)站共分(fen)左岸(an)電(dian)(dian)(dian)站、右岸(an)電(dian)(dian)(dian)站、右岸(an)地下(xia)電(dian)(dian)(dian)站和(he)(he)電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)站四個電(dian)(dian)(dian)站，分(fen)別設計安裝14臺(tai)(tai)70萬(wan)(wan)千(qian)瓦(wa)、12臺(tai)(tai)70萬(wan)(wan)千(qian)瓦(wa)、6臺(tai)(tai)70萬(wan)(wan)千(qian)瓦(wa)和(he)(he)2臺(tai)(tai)5萬(wan)(wan)千(qian)瓦(wa)水輪(lun)發(fa)電(dian)(dian)(dian)機(ji)(ji)(ji)組(zu)，總(zong)裝機(ji)(ji)(ji)容(rong)量達(da)2250萬(wan)(wan)千(qian)瓦(wa)。其中(zhong)左岸(an)電(dian)(dian)(dian)站首臺(tai)(tai)機(ji)(ji)(ji)組(zu)于2003年7月10日正(zheng)式(shi)并網發(fa)電(dian)(dian)(dian)，左岸(an)電(dian)(dian)(dian)站14臺(tai)(tai)機(ji)(ji)(ji)組(zu)于2005年9月全部投(tou)產(chan)發(fa)電(dian)(dian)(dian)；右岸(an)電(dian)(dian)(dian)站首臺(tai)(tai)機(ji)(ji)(ji)組(zu)于2007年6月11日正(zheng)式(shi)并網發(fa)電(dian)(dian)(dian)，目(mu)前已有(you)5臺(tai)(tai)機(ji)(ji)(ji)組(zu)投(tou)產(chan)發(fa)電(dian)(dian)(dian)；電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)站2臺(tai)(tai)機(ji)(ji)(ji)組(zu)也(ye)于2007年2月全部投(tou)產(chan)發(fa)電(dian)(dian)(dian)。截至目(mu)前，三(san)峽電(dian)(dian)(dian)站投(tou)產(chan)機(ji)(ji)(ji)組(zu)裝機(ji)(ji)(ji)容(rong)量累計達(da)到1340萬(wan)(wan)千(qian)瓦(wa)，形(xing)成和(he)(he)鞏固了以(yi)三(san)峽為(wei)中(zhong)心的(de)我國電(dian)(dian)(dian)網南北(bei)互聯、西電(dian)(dian)(dian)東送的(de)格(ge)局。
三峽(xia)(xia)電(dian)(dian)站(zhan)自(zi)2003年左岸(an)電(dian)(dian)站(zhan)首批(pi)機組(zu)投產發(fa)電(dian)(dian)以來，歷(li)年發(fa)電(dian)(dian)量分別(bie)為86億千(qian)(qian)瓦時(shi)、392億千(qian)(qian)瓦時(shi)、491億千(qian)(qian)瓦時(shi)、493億千(qian)(qian)瓦時(shi)和538億千(qian)(qian)瓦時(shi)（2007年前11個月發(fa)電(dian)(dian)量），送往華中電(dian)(dian)網、送華東電(dian)(dian)網和南方(fang)電(dian)(dian)網的(de)(de)電(dian)(dian)量比例分別(bie)為30.8%、43.5%和25.7%。三峽(xia)(xia)電(dian)(dian)站(zhan)發(fa)出的(de)(de)強大(da)、優質清潔電(dian)(dian)能有(you)力地緩解(jie)了當前用電(dian)(dian)緊張(zhang)的(de)(de)局面，促進了環境(jing)改善。
