Tillari Hydro-Electrical Project 1x60MW

The Construction of TILLARI HYDRO_ELECTRIC PROJECT heralds the fulfilment of a long cherished dream of millions of people of Konkan belt. Its completion boosted Social, Economic & Industrial advancement of the entire area. Salient features of TILLARI HYDRO-ELECTRIC PROJECT : 60 MW executed are :
The main water storage for Tillari Hydro Electric Project is formed by Construction of a masonry dam, 38m high, across the Tillari River, with a capacity of about 113m. cum(4 T.M.C.)The impounded water will be led through a "Power Canal" 15 km in length to balancing reservoir formed by construction of a Forebay Dam ( masonry ).
  Approach Tunnel Of T.H.E.P.(7.5 x 6.7)

The water conductor system from the Forebay dam onwards consists of a 1233m long Head Race Tunnel, 380m long open penstock, followed by 758m long underground pressure shaft, leading water into an underground Power House, located about 300m below ground level. One 60 MW generator coupled to a Pelton-wheel.
Water after generation of power, is taken out through a 4815m long Tail Race Tunnel and 1105m long open tail Race Channel to river "Kharari", which finally joins rivar Tillari. The underground Power House is approachable through 833m long Approach Tunnel and ventilated through 500m long Ventilation Tunnel.The main Switchyard is located near Approach Tunnel Portal.
