自5月中旬以來，貴州遭遇了長時間、大范圍的持續降雨，全省來水充足，進入豐水期，7月底貴州全流域水電蓄能值達97億千瓦時，為歷史最高水平。
貴州(zhou)(zhou)電(dian)(dian)(dian)網(wang)公司密切跟(gen)蹤來水(shui)(shui)(shui)情況，優化水(shui)(shui)(shui)火電(dian)(dian)(dian)發電(dian)(dian)(dian)方案，有(you)計劃地(di)安排火電(dian)(dian)(dian)機(ji)組停(ting)機(ji)配(pei)合調峰，全力(li)吸納水(shui)(shui)(shui)電(dian)(dian)(dian)，最大限度地(di)減少棄水(shui)(shui)(shui)。自(zi)５月(yue)初，貴州(zhou)(zhou)電(dian)(dian)(dian)網(wang)公司安排龍(long)頭水(shui)(shui)(shui)電(dian)(dian)(dian)站洪家渡(du)電(dian)(dian)(dian)廠攔蓄洪水(shui)(shui)(shui)，并(bing)安排紅楓梯級、大花水(shui)(shui)(shui)、格里橋、普(pu)定(ding)等調節性能(neng)較弱的(de)水(shui)(shui)(shui)電(dian)(dian)(dian)站全天滿發，提(ti)前消落水(shui)(shui)(shui)位；充分(fen)依靠南方電(dian)(dian)(dian)網(wang)資源(yuan)優化配(pei)置大平臺的(de)作用，進一步加(jia)大西(xi)(xi)電(dian)(dian)(dian)東(dong)(dong)送力(li)度，5－7月(yue)西(xi)(xi)電(dian)(dian)(dian)東(dong)(dong)送比計劃多送63億千瓦時。自(zi)7月(yue)17日以來，貴州(zhou)(zhou)西(xi)(xi)電(dian)(dian)(dian)東(dong)(dong)送電(dian)(dian)(dian)力(li)按通道最大能(neng)力(li)滿送，保持在730萬千瓦左右，日均電(dian)(dian)(dian)量超1.7億千瓦時。
