Luhri Hydro Electric Project is a run of the river scheme on the right bank of Satluj River. Dam of the project is located near Nirath village about 100 Km from Shimla on NH-22 in Distt. Shimla, Kullu and Mandi of Himachal Pradesh and under ground Power House at village Marola on Sunni – Sainj road approximately 60 Km from Shimla. It is envisaged to construct a 86m high concrete gravity Dam. With a catchments area of 51600 sq. Km with two intake gates, a design discharge of 480 Cumcs of water is proposed to be diverted after sedimentation of 0.1 mm particle size through 9.0m dia, circular twin tunnels on the right bank of Satluj River in a length of 38.14 Km which shall terminate in 9.0 m dia. Surge Tunnel ( Gallery). Eight no. adits have been proposed for excavation of head race tunnel . Water shall enter into a 5m dia 173.5m long pressure shaft which will feed four No. Francis turbines in under ground power house with net head of 181m to generate 775 MW of Power.
The project is estimated to cost Rs. 6080 crore at December, 2010 price level and annual energy generation in 90% dependable year shall be 3142 million units and in 50% dependable year shall be 3727 million units. Further, the sale rate of power per unit with 12% free power shall be Rs. 4.90 and levellised tariff shall be Rs. 4.51. It is proposed to complete the project in 8 years excluding one year for pre-construction activities.  It is proposed to complete the project in 8 years excluding one year for pre-construction activities.
