10月6日下午，西藏自治區當雄縣發生6.6級地(di)震(zhen)，羊(yang)湖(hu)抽水蓄能電廠、羊(yang)八(ba)井(jing)地(di)熱(re)電廠因距離(li)震(zhen)中(zhong)格達鄉較近，受到一定影響，但(dan)藏中(zhong)電網(wang)運行正常(chang)，電力供應基本穩定。
地震(zhen)(zhen)發生后，國(guo)家電(dian)網公(gong)(gong)司(si)第一(yi)時間了(le)解西(xi)藏(zang)電(dian)力(li)有限公(gong)(gong)司(si)損失情(qing)況，部(bu)署(shu)加(jia)強設備(bei)巡(xun)視，做(zuo)好抗震(zhen)(zhen)搶險工作。
國家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)西藏(zang)公司迅速(su)組織所屬各單位(wei)人員對發(fa)(fa)(fa)供電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備、設(she)施(shi)和建筑(zhu)物進(jin)行(xing)(xing)巡視檢查，發(fa)(fa)(fa)現(xian)羊湖抽水蓄能電(dian)(dian)(dian)(dian)(dian)(dian)廠(chang)(chang)壓力管(guan)道縱向移位(wei)11毫(hao)米，管(guan)道邊坡有3處垮塌(ta)。為避免(mian)發(fa)(fa)(fa)生險情以致影(ying)響藏(zang)中(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)正常運(yun)行(xing)(xing)，西藏(zang)公司暫停羊湖電(dian)(dian)(dian)(dian)(dian)(dian)廠(chang)(chang)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)，并于19時(shi)(shi)15分至(zhi)22時(shi)(shi)55分之間，啟動(dong)了拉(la)薩電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)應(ying)急電(dian)(dian)(dian)(dian)(dian)(dian)源共4臺機組發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)，同時(shi)(shi)將直孔水電(dian)(dian)(dian)(dian)(dian)(dian)廠(chang)(chang)調至(zhi)滿負荷(he)運(yun)行(xing)(xing)，保證了當(dang)晚用電(dian)(dian)(dian)(dian)(dian)(dian)高峰(feng)時(shi)(shi)段(duan)的正常電(dian)(dian)(dian)(dian)(dian)(dian)力供應(ying)。此外，羊八井地(di)(di)熱電(dian)(dian)(dian)(dian)(dian)(dian)廠(chang)(chang)一分廠(chang)(chang)廠(chang)(chang)房因地(di)(di)震出(chu)現(xian)明顯(xian)裂紋，但發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備運(yun)行(xing)(xing)正常。
為確保及(ji)時有效應對地震造成的影響，預防災害(hai)再次襲(xi)來，國家電(dian)網(wang)西藏(zang)公司(si)加強了各電(dian)源點、變電(dian)站、輸(shu)電(dian)線路和(he)廠區廠房等重點部位(wei)的巡視，要(yao)求所屬(shu)各單位(wei)主(zhu)要(yao)負責人到崗指揮抗震搶險。截至10月7日下午，藏(zang)中(zhong)電(dian)網(wang)除羊湖(hu)電(dian)廠外其他電(dian)源點及(ji)主(zhu)網(wang)運(yun)行(xing)基(ji)(ji)本(ben)正常，電(dian)力供應基(ji)(ji)本(ben)能夠保證人民生產生活(huo)需求，未因(yin)地震災害(hai)而拉閘限電(dian)。
