Super Madi Hydroelectric Project is located in Kaski Districts, Gandaki Zone of Western Development Region of Nepal. The project lies in the Namarjun and Parche Village Development Committees of Kaski District. The headworks is located at the foothill of Sikles village and the powerhouse is located just opposite of Sodha village. The project lies about 23 km north-east of Pokhara. At present there is about 16km long earthen road access towards the project from Pokhara City. An earthen road track has already reached to the Headrace Tunnel outlet which lies in the Namarjun Village Development Committee at the left bank of the Madi River. This project is a simple Run-of-River scheme that utilizes the flow in Madi River. Madi River is one of the major tributaries of the Narayani River of the Gandaki basin after mixing with the Seti River. The proposed project has installed capacity of 44MW, design discharge of 18m3/sec and net head of 295m. A simple boulder riprap diversion weir across the Madi Khola diverts the water into the side intake. A gravel trap settles gravels coming through the six orifices of the intake and takes to the headpond through approach box culvert. Two underground settling basins are fed with the discharge by two inlet tunnels from the headpond. An outlet pond after the settling basins feed water into headrace tunnel. The headrace tunnel of length 5905m of finished diameter of 3.6~4.4m and steel penstock pipe of average diameter 2.6m and length 1381m feed water to the three units of vertical axis Pelton Turbines installed in the semi-surface powerhouse to generate 44000kW power. The water will then be discharge back into the Madi River through 281m long tailrace. An underground surge tank is provisioned at the end of the headrace tunnel. An access tunnel to the headworks, two Adit tunnels to access the underground settling basins, three Adit tunnels to access the headrace tunnel and a ventilation tunnel to reach the top of the underground surge tank are provisioned. The electricity generated from this plant will be connected to the Integrated Nepal Power System (INPS) at the Lekhnath Sub Station at Lekhanath Municipality near Pokhara City through 22km long 132kV single circuit transmission line. The total net energy production will be 243GWh annually.
