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(gui)州(zhou)電(dian)(dian)(dian)網公司(si)密切跟蹤來水(shui)(shui)情況(kuang)，優化(hua)水(shui)(shui)火電(dian)(dian)(dian)發(fa)電(dian)(dian)(dian)方案，有計劃(hua)地安排(pai)火電(dian)(dian)(dian)機組停機配合調峰，全(quan)力吸(xi)納水(shui)(shui)電(dian)(dian)(dian)，最大(da)限度地減少棄水(shui)(shui)。自(zi)５月(yue)初，貴(gui)州(zhou)電(dian)(dian)(dian)網公司(si)安排(pai)龍(long)頭(tou)水(shui)(shui)電(dian)(dian)(dian)站洪(hong)家渡(du)電(dian)(dian)(dian)廠攔(lan)蓄洪(hong)水(shui)(shui)，并安排(pai)紅(hong)楓梯級、大(da)花(hua)水(shui)(shui)、格里橋、普定等(deng)調節(jie)性能較弱(ruo)的水(shui)(shui)電(dian)(dian)(dian)站全(quan)天滿(man)發(fa)，提前消落水(shui)(shui)位；充分依(yi)靠南方電(dian)(dian)(dian)網資(zi)源優化(hua)配置大(da)平(ping)臺的作用，進(jin)一步加大(da)西電(dian)(dian)(dian)東送(song)(song)力度，5－7月(yue)西電(dian)(dian)(dian)東送(song)(song)比計劃(hua)多送(song)(song)63億(yi)千瓦(wa)時(shi)(shi)。自(zi)7月(yue)17日(ri)以來，貴(gui)州(zhou)西電(dian)(dian)(dian)東送(song)(song)電(dian)(dian)(dian)力按通道(dao)最大(da)能力滿(man)送(song)(song)，保持在730萬千瓦(wa)左右(you)，日(ri)均電(dian)(dian)(dian)量超(chao)1.7億(yi)千瓦(wa)時(shi)(shi)。
