The power station is a high-head unregulated radial power station. It mainly undertakes power generation tasks, taking into account factors such as unit operation reliability and flexibility, convenient maintenance and engineering economy. It adopts horizontal units, the number of units is 2, and the single unit capacity is 4000 kilowatts. . After the completion of the project, the average power generation for many years reached 41.48 million kilowatt-hours, and the installed annual utilization hours were 5,185 hours. The project was officially merged into the Nujiang Power Supply Bureau of the Southern Power Grid for power generation in February 2013. The completion of the project gave full play to and utilized the hydropower resources of the Pianma River, promoted the optimal allocation and sustainable use of water resources in the Pianma River Basin, and also promoted the economic development of the Pianma River Basin.
