The Mupo Hydropower Station developed and invested by China Electric Power Construction is connected to the grid for power generation.
The No. 1 and No. 2 units of the Mupo Hydropower Station in the Xiaojinchuan River Basin, Aba Prefecture, developed and invested by China Electric Power Construction Group Sichuan Company, have officially connected to the grid and entered commercial operation. The completion and commissioning of this power station play an important role in promoting economic development in national-level minority poverty-stricken areas after disaster reconstruction and alleviating the regional power supply and demand contradiction.
The Mupo Hydropower Station is the third level of the "one reservoir and five levels" plan for the main stream of the Fubian River in Aba Prefecture. It is a key hydropower development project in Aba Prefecture. The hydropower station is developed in a mixed manner, with a water diversion tunnel length of 10.074 kilometers. The designed annual power generation of the hydropower station is 191 million kilowatt-hours, with 3 units installed, each with a capacity of 15 megawatts, totaling an installed capacity of 45 megawatts.
The Mupo Hydropower Station was approved by the Provincial Development and Reform Commission on January 29, 2010, and the main project officially started construction on June 1. During the construction process, it faced severe geological conditions, significant external interference, the Lushan "4.20" earthquake, and the Chengdu West "7.10" torrential rain and mudslide disasters, among other challenges. After the joint efforts of the project owner, supervision, design, and construction units, the main project construction was completed on November 30, 2013, and water storage was completed on December 12, meeting the power generation requirements, but could not be connected to the grid for debugging due to limitations from the Xiaojin 220 kV substation.
In early April this year, after the Xiaojin 220 kV substation was put into operation, the project owner immediately organized the commissioning of the 220 kV "Mujin Line" outgoing project, the main transformer impact test, and the unit grid connection debugging. The two units underwent simultaneous load, load shedding, and 72-hour trial operation tests. They are currently operating stably with excellent performance, and all major indicators such as unit vibration, swing, and temperature at various parts meet design requirements.
The Mupo Hydropower Station is undertaken by the Xiaojinchuan Company, which is controlled by Sichuan Company, responsible for the preparation, construction, and operation management tasks. It is the first project to be completed and put into operation among the six power stations planned in the near term for the Xiaojinchuan Basin.
