　　國家重點建設項目、浙江省目前最大的扶貧致富項目——灘坑水電站工程3號機組7月10日20時通過72小時連續試運行后投入商業運行。至此，由中國水電十二局有限公司為主承建的灘坑水電站3臺20萬千瓦水力發電機組全部建成投產發電，灘坑水電站成為位居新安江水電站之后浙江省第二大常規水電站。

　　灘坑(keng)水電站(zhan)是“十(shi)五”期間浙(zhe)江(jiang)省(sheng)實(shi)施(shi)建設的(de)最(zui)大水電工程，電站(zhan)位于浙(zhe)江(jiang)省(sheng)青田縣境內的(de)甌江(jiang)支流小溪中游河段。電站(zhan)1號、2號機組分別于2008年8月16日(ri)、2009年2月12日(ri)投產發電。截至7月10日(ri)，灘坑(keng)水電站(zhan)3臺機組已經累(lei)計發電2.28億(yi)千(qian)瓦時，對(dui)浙(zhe)江(jiang)省(sheng)電網起到了積極的(de)調(diao)峰作(zuo)用(yong)。
