據統計，截止到2007年(nian)11月(yue)2日，三峽電(dian)站歷年(nian)累計發電(dian)量(liang)突破2000億千瓦時(shi)。這相當(dang)于(yu)少燃燒(shao)8000多(duo)萬噸標準煤。
三(san)峽(xia)電(dian)(dian)(dian)站(zhan)(zhan)共分左(zuo)(zuo)岸電(dian)(dian)(dian)站(zhan)(zhan)、右(you)岸電(dian)(dian)(dian)站(zhan)(zhan)、右(you)岸地(di)下電(dian)(dian)(dian)站(zhan)(zhan)和(he)電(dian)(dian)(dian)源電(dian)(dian)(dian)站(zhan)(zhan)四(si)個電(dian)(dian)(dian)站(zhan)(zhan)，分別設計安裝14臺(tai)(tai)(tai)(tai)70萬(wan)千瓦(wa)(wa)(wa)(wa)、12臺(tai)(tai)(tai)(tai)70萬(wan)千瓦(wa)(wa)(wa)(wa)、6臺(tai)(tai)(tai)(tai)70萬(wan)千瓦(wa)(wa)(wa)(wa)和(he)2臺(tai)(tai)(tai)(tai)5萬(wan)千瓦(wa)(wa)(wa)(wa)水(shui)輪發(fa)電(dian)(dian)(dian)機組(zu)，總裝機容(rong)量達2250萬(wan)千瓦(wa)(wa)(wa)(wa)。其中左(zuo)(zuo)岸電(dian)(dian)(dian)站(zhan)(zhan)首(shou)(shou)臺(tai)(tai)(tai)(tai)機組(zu)于(yu)2003年(nian)7月10日正式(shi)(shi)并網(wang)發(fa)電(dian)(dian)(dian)，左(zuo)(zuo)岸電(dian)(dian)(dian)站(zhan)(zhan)14臺(tai)(tai)(tai)(tai)機組(zu)于(yu)2005年(nian)9月全(quan)部(bu)投(tou)產(chan)發(fa)電(dian)(dian)(dian)；右(you)岸電(dian)(dian)(dian)站(zhan)(zhan)首(shou)(shou)臺(tai)(tai)(tai)(tai)機組(zu)于(yu)2007年(nian)6月11日正式(shi)(shi)并網(wang)發(fa)電(dian)(dian)(dian)，目(mu)前已(yi)有5臺(tai)(tai)(tai)(tai)機組(zu)投(tou)產(chan)發(fa)電(dian)(dian)(dian)；電(dian)(dian)(dian)源電(dian)(dian)(dian)站(zhan)(zhan)2臺(tai)(tai)(tai)(tai)機組(zu)也于(yu)2007年(nian)2月全(quan)部(bu)投(tou)產(chan)發(fa)電(dian)(dian)(dian)。截(jie)至目(mu)前，三(san)峽(xia)電(dian)(dian)(dian)站(zhan)(zhan)投(tou)產(chan)機組(zu)裝機容(rong)量累(lei)計達到1340萬(wan)千瓦(wa)(wa)(wa)(wa)，形成和(he)鞏(gong)固了以三(san)峽(xia)為中心(xin)的我國電(dian)(dian)(dian)網(wang)南北互聯(lian)、西電(dian)(dian)(dian)東(dong)送的格局。
三(san)峽電(dian)站(zhan)自2003年(nian)左岸電(dian)站(zhan)首(shou)批機組投產(chan)發(fa)(fa)電(dian)以來，歷(li)年(nian)發(fa)(fa)電(dian)量分別為86億(yi)千瓦時、392億(yi)千瓦時、491億(yi)千瓦時、493億(yi)千瓦時和(he)(he)538億(yi)千瓦時（2007年(nian)前(qian)11個月(yue)發(fa)(fa)電(dian)量），送(song)往華中電(dian)網、送(song)華東電(dian)網和(he)(he)南(nan)方電(dian)網的電(dian)量比例分別為30.8%、43.5%和(he)(he)25.7%。三(san)峽電(dian)站(zhan)發(fa)(fa)出的強大、優質(zhi)清潔(jie)電(dian)能有力地(di)緩(huan)解了(le)當前(qian)用電(dian)緊張的局面，促進(jin)了(le)環境改善(shan)。
