據統計(ji)，截止到(dao)2007年(nian)11月2日，三峽電站歷年(nian)累計(ji)發電量突破(po)2000億千瓦時。這相當于(yu)少燃燒(shao)8000多萬噸標準煤。
三峽(xia)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)共(gong)分(fen)左(zuo)岸(an)(an)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)、右岸(an)(an)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)、右岸(an)(an)地下電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)和(he)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)四個(ge)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)，分(fen)別設計安裝14臺(tai)70萬(wan)(wan)(wan)千(qian)瓦、12臺(tai)70萬(wan)(wan)(wan)千(qian)瓦、6臺(tai)70萬(wan)(wan)(wan)千(qian)瓦和(he)2臺(tai)5萬(wan)(wan)(wan)千(qian)瓦水輪發(fa)(fa)電(dian)(dian)(dian)機(ji)(ji)(ji)組(zu)，總裝機(ji)(ji)(ji)容(rong)量達2250萬(wan)(wan)(wan)千(qian)瓦。其中(zhong)左(zuo)岸(an)(an)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)首(shou)(shou)臺(tai)機(ji)(ji)(ji)組(zu)于(yu)2003年7月10日正式(shi)并網(wang)發(fa)(fa)電(dian)(dian)(dian)，左(zuo)岸(an)(an)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)14臺(tai)機(ji)(ji)(ji)組(zu)于(yu)2005年9月全(quan)部投(tou)產發(fa)(fa)電(dian)(dian)(dian)；右岸(an)(an)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)首(shou)(shou)臺(tai)機(ji)(ji)(ji)組(zu)于(yu)2007年6月11日正式(shi)并網(wang)發(fa)(fa)電(dian)(dian)(dian)，目前(qian)已有5臺(tai)機(ji)(ji)(ji)組(zu)投(tou)產發(fa)(fa)電(dian)(dian)(dian)；電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)2臺(tai)機(ji)(ji)(ji)組(zu)也于(yu)2007年2月全(quan)部投(tou)產發(fa)(fa)電(dian)(dian)(dian)。截至目前(qian)，三峽(xia)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)投(tou)產機(ji)(ji)(ji)組(zu)裝機(ji)(ji)(ji)容(rong)量累計達到1340萬(wan)(wan)(wan)千(qian)瓦，形成(cheng)和(he)鞏固了以(yi)三峽(xia)為中(zhong)心(xin)的我國電(dian)(dian)(dian)網(wang)南北(bei)互聯(lian)、西電(dian)(dian)(dian)東送的格(ge)局(ju)。
三(san)峽電(dian)站自2003年左岸(an)電(dian)站首批機組投(tou)產(chan)發(fa)電(dian)以來，歷年發(fa)電(dian)量分(fen)別(bie)為86億(yi)(yi)千瓦(wa)(wa)時、392億(yi)(yi)千瓦(wa)(wa)時、491億(yi)(yi)千瓦(wa)(wa)時、493億(yi)(yi)千瓦(wa)(wa)時和538億(yi)(yi)千瓦(wa)(wa)時（2007年前11個月(yue)發(fa)電(dian)量），送往華中(zhong)電(dian)網、送華東(dong)電(dian)網和南(nan)方電(dian)網的電(dian)量比例(li)分(fen)別(bie)為30.8%、43.5%和25.7%。三(san)峽電(dian)站發(fa)出的強大(da)、優質清潔電(dian)能有力地緩解了當前用電(dian)緊張的局(ju)面，促進了環境改善。
