Dewali 13 MW

The 13 MW Dewali hydro-electric power project is in the final stages of conceptualisation with construction scheduled to start in autumn 2011. The development cost for the project is currently estimated to be 120 Crores (US$ 27 Million) with an operational capacity to generate 69.89 Million kWh per annum. The project comprises a 30 m wide, 52 m long dam/weir feeding 14.5 cumecs of water through a silting basin into the water conduit system. The conduit system comprises of a 160 metre long box shaped reinforced cement concrete channel leading into a 1.8 kilometre tunnel and then into a 1.05 kilometre reinforced cement concrete rectangular box channel. This leads into the fore-bay, which shall be a rectangular reinforced cement concrete tank with dimensions of 15m x 6m x 9m. Leaving the fore-bay is the penstock, which shall consist of one pipe of length 860m, internal diameter 2.4m bifurcating into two pipes of length 17m, internal diameter 1.7m. The bifurcated pipes lead into two horizontal Francis turbines of output 7280 kW each.
