茗洋关梯级水电站是上饶电网的骨干电站,现已建成一、二、三级,装机六台,总装机容量为3660千瓦。其中一级为坝后式电站,装机两台共760千瓦,二级装机2×1250千瓦,三级为2×200于瓦。全部电力经35千伏线路联入上饶电网,年发电量达1250万度,在系统中占有一定的比重,同时,发电尾水全部引入灌溉总干渠灌溉上饶、横峰两县四万亩农田。由于二级电站水头高(75米),装机容量也较大,为梯级中的中心电站,其引水渠道长
Mingyangguan cascade hydropower station is the backbone of Shangrao Power Station, has been completed one, two, three, installed capacity of six units with a total installed capacity of 3660 kilowatts. One of them is a dam-type hydropower station with installed capacity of 760 kW, two installed capacity of 2 × 1250 kW and three levels of 2 × 200 at watts. All electricity is connected to Shangrao Power Grid via 35-kilovolt line, with an annual generating capacity of 12.5 million kilowatts, accounting for a certain proportion in the system. At the same time, the tailrace of power generation is fully introduced into the irrigation main canal to irrigate 40,000 mu of farmland in Shangrao and Hengfeng counties.
