龍背灣水電站是堵河流域待開發的優質調峰電源和龍頭項目，電站竣工后，將對提高流域電源整體競爭能力，提高南水北調中線供水保障能力，促進竹山、竹溪、房縣庫區群眾脫貧致富和區域經濟發展發揮重要作用。工程規模屬大（2）型，工程等別為二等，主要建筑物大壩為一級建筑物。水庫正常蓄水位520.0m，水庫最大庫容8.3億m3，電站總裝機2×90MW，電站設計引用流量170.6m3/s。 該項目于2008年啟動前期工作，今年2月開始動工壩區場平、施工電源、施工道路、導流洞進出口、壩肩開挖等臨建工程。目前，該項目已完成移民安置規劃大綱、土地預審、環保影響評價、水土保持、防洪規劃、使用林地等17個專題報告的評審批復工作。。至(zhi)(zhi)2014年10月(yue)12日11點18分(fen)，132噸的鋼(gang)閘門隨著起重機(ji)(ji)的轉動緩緩落下，龍背灣水(shui)電(dian)站(zhan)(zhan)順利下閘，開始蓄(xu)水(shui)。這(zhe)標志著堵河干流水(shui)電(dian)開發(fa)全(quan)面完成，至(zhi)(zhi)此竹山縣水(shui)電(dian)站(zhan)(zhan)總(zong)裝機(ji)(ji)達到90萬千瓦，水(shui)電(dian)大縣之夢順利實現。
