EthiopiaGD-3The hydroelectric power station is located in Oromia State, Ethiopia, approximately to the southeast of the capital, Addis Ababa.400kilometers, near the border of Somalia and Kenya, is inGenale-Dawariver planning6stage in3stage of the hydroelectric power station, and it is also the first large-scale hydroelectric power station project built on this river.

 

GD-3Normal water level elevation of the hydroelectric power station1120meters, total installed capacity254megawatts, consisting of3units84.7megawatt vertical shaft mixed-flow hydraulic turbine generator units. The contract amount for this power station is4.51US dollars. It is a comprehensive water conservancy project that mainly generates electricity and also serves irrigation and downstream ecological water use. It was one of the largest hydroelectric power stations under construction in Ethiopia at that time.

 

GD-3The hydroelectric power station mainly consists of three major parts: dam area structures, water conveyance system structures, and power plant structures. The dam is a face rockfill dam with a maximum dam height of110m,and a dam crest length of426m,and the diversion tunnel was used for diversion during the dam construction. The total length of the water conveyance system is14km,the intake is located on the left bank upstream of the dam, and between the intake and the surge shaft is a12.8kmlong water diversion tunnel, of which10.4kmuses a tunnel boring machineTBMfor long-distance tunnel excavation. The surge shaft height is127m,and the diameter is23m,and the shaft height is222m,and the diameter is6.1m。The powerhouse is underground, and the main structures include the underground main powerhouse, main transformer room, auxiliary powerhouse, access tunnel, and ground switch station.

 

GD-3After the hydroelectric power station was connected to the grid, it greatly improved the tight power supply situation in Ethiopia and effectively promoted local livelihood and development.
