VARAHI HYDROELECTRIC PROJECT - KARNATAKA
KARNATAKA- A NATURALLY POWERFULL STATE Karnataka a many splendored land, as through nature has taken a special liking towards this state. One sixth of the state terrain is mountainous and prone to heavy rain fall. This area is known as MALNAD (land of mountains).

THE RIVER VARAHI The river VARAHI has its origin in the western Ghats of Karnataka and flows into the Arabian sea. Taking its birth at 730m above sea level at a place called “HEBBAGILU” near Agumbe (called Chirapunji of the Karnataka ) at Thirthahalli taluk in Shivamogga district. Many of sub rivers join the VARAHI, these rivers are is originated in ShettykoppaATHITH.D, Halige, Kollavadi, Bangaragall, etc.., The major flow of VARAHI takes place in surroundings Hosanagara taluk. The river traversing about 25km from its origin, falls by 455m in cascades which is popularly known as “KUNCHIKAL FALLS”. The annual rainfall in the catchment varies from 200mm-12800mm. The river join Arabian sea near Kundapur in Udupi district. The consequence of this drop in the river courses and the large quantum of runoff from the monsoon fed catchment area  is the construction of “VARAHI HYDEL POWER PROJECT” According to mythology, VARAHA is one of the incarnations of lord Vishnu.

THE PROJECT The “VARAHI HYDRO ELECTRIC PROJECT” has distinction of being state’s first “UNDER GROUND POWER HOUSE”. The project include construction of three dams,namly 1.	Mani dam 2.	Pick-up dam 3.	Fore bay dam With these three dams, the main Mani reservoir supported by nine(9) saddle dam total length of 835m on the left bank and three(3) saddle dams of total length of 715m on right bank. A dam power house and underground power house with an ultimate power potential of 469MW in two stages. The 3 dams and DAM POWER HOUSE located at Yadur in Hosanagara taluk. (Shivamogga district). The pressure shaft and state first underground power house located at Hosangadhi  in Kundapura taluk (Udupi district).

KARNATAKA- A LAND OF MANY FIRSTS

1.Survey of hydel resources as early as 1898.

2.Establishment of Asia’s first giant Hydroelectric station at shivansamudram.

KARNATAKA POWER CORPORATION LIMITED (KPCL)

In the late sixties, the phenomenal demand for electricity necessitated, systematic effort by the state government to increase the availability of electric power. This result in inception of KPCL in ****.

CONSTRUCTION DETAIL OF THE PROJECT The Varahi hydroelectricity project has distinction of being states first UNDERGROUND powerhouse. Excavation by tunneling methods has been made to an extent of 6.9kms.

UNDER GROUND States first UPH. A huge cavern with floor size of 155mX20m-50m deep for housing the generating units.

TURBINES

→IN MANI DAM POWER HOUSE -      Two vertical axies KAPLAN TURBINE coupled to the generator of 4.5MW  each.

→IN UPH HOSANGHADHI  -Two turbines of PELTON WHEEL OF VERTICLE AXIES type have been coupled with the two generating units of 115MW each.

REHABILITATION

Under Varahi project an extent of 5707 Hectares of forest and government lands, 1849 Hectares of private lands have submerged in 25 villages. The submerged villages are Kolur ,Kallasulli ,Matthiga ,Baise ,Hemmgodu,Idur, Hirige ,Hollegadde ,Baldhale ,kunnimakhi ,Hedna ,Kharigallu ,Bhallegodu ,Themmemane] ,Bhallehalli ,Thalageri ,Hossaghadde ,Lakmane ,Ekkhade [Halige, Doddhinamane ,Korkote ,Karakhihakklu , Kogre , Ulthga. The displaced families have been given adequate compensation, exgratia payments, rehabilitation grants as per the norms fixed by the government. Free transportation facilities has been arranged to shift the materials.
