Damodar Valley Corporation

Damodar Valley Corporation, popularly known as DVC, came into being on July 7, 1948 by an Act of the Constituent Assembly (Act No. XIV of 1948) as the first multipurpose river valley project of independent India.


At the time of its inception, the objectives were flood control, provision of water for irrigation and other uses, generation, transmission and distribution of electricity, eco-conservation and afforestation and socio-economic well being of the people residing in and around DVC Projects. However, with the passage of time and shift in National priorities, power generation with associated transmission and bulk distribution activities gained priority in DVC in view of its locational advantage. Other objectives of DVC, however, received due attention and services as part of its overall responsibility.



DVC, a legacy to the people of India, emerged as a culmination of attempts made over a whole century to control the wild and erratic Damodar river. The river spans over an area of 25,000 sq. kms covering the states of Bihar (now Jharkhand) & West Bengal.


The Damodar Valley has been ravaged frequently by floods of varying intensities and the first of the major recorded flood dates back to 1730. Thereafter serious floods occurred at regular intervals, but it was the flood of 1943 that left the worst devastation in its wake. As a result, the Governor of Bengal appointed a Board of Inquiry headed by the Maharaja of Burdwan and the noted physicist Dr. Meghnad Saha as member. In their report, the Board suggested creation of an authority similar to the Tennessee Valley Authority (TVA) of United States of America. The Government of India then appointed Mr. W.L. Voorduin, a senior engineer of the TVA to make recommendations for comprehensive development of the valley. Accordingly, in August, 1944, Mr. Voorduin submitted his "Preliminary Memorandum on the Unified Development of the Damodar River".


Mr. Voorduin’s "Preliminary Memorandum" suggested a multipurpose development plan designed for achieving flood control, irrigation, power generation and navigation in the Damodar Valley. Four consultants appointed by the Government of India examined it. They also approved the main technical features of Voorduin’s scheme and recommended early initiation of construction beginning with Tilaiya to be followed by Maithon.

By April 1947, full agreement was practically reached between the three Governments of Central, Bengal and Bihar on the implementation of the scheme and in March 1948, the Damodar Valley Corporation Act (Act No. XIV of 1948) was passed by the Central Legislature, requiring the three governments – the Central Government and the State Governments of West Bengal and Bihar (now Jharkhand) to participate jointly for the purpose of building the Damodar Valley Corporation.


The Corporation came into existence on 7th July, 1948 as the first multipurpose river valley project of independent India.


The Dams - Power Generation

The first dam was built across the Barakar River, a tributary of the Damodar River at Tilaiya 1953. The second one, Konar Dam, was built across the Konar River, another tributary of the Damodar River at Konar in 1955. Two dams across the rivers Barakar and Damodar were built at Maithon in 1957 and Panchet in 1959. Both the dams are some 8 km upstream of the confluence point of the rivers. These four major dams are controlled by DVC. Durgapur Barrage was constructed downstream of the four dams in 1955, across the Damodar river at Durgapur in 1955, with head regulators for canals on either side for feeding an extensive system of canals and distributaries.


DVC proposes to construct a dam across the Barakar river at Belpahari in Jharkhand state.There are hydro-electric power stations at Tilayia, Maithon and Panchet, with total installed capacity of 144 MW. The one at Maithon was India's first underground hydro-electric power station.


DVC operates thermal power stations at Bokaro, Chandrapura, Durgapur and Mejia, with total derated capacity of 2745 MW. The power station at Bokaro was biggest in the country when it was built in the fifties.Mejia, first of its kind in Eastern India with tube mills in service for zero reject.Direct ignition of pulverized coal (DIPC) system for reducing oil consumption in the boiler conceived for the first time in Eastern India at Mejia TPS.


DVC is expanding its thermal power capacity and with the completion of its present plans by 2012 it would be generating more than 11000 MW of power. The forthcoming projects are Raghunathpur TPS (4x600 MW), Andal TPS (2x500 MW), Koderma TPS (2x500 MW), Maithan RB TPS (2x525 MW) and Bokaro A TPS (1x600 MW)and Bokaro Steel City TPS (3x250 MW).


The total valley area covered by DVC activities is approximately 24,235 square kilometres The upper valley consists of the districts of Hazaribagh, Koderma, Giridih, Chatra, Dhanbad and Bokaro, and some sections of Palamau, Ranchi, Lohardaga and Dumka districts in the state of Jharkhand. The lower valley consists of the two districts of Bardhaman and Hughli, and some areas of the Howrah, Bankura, and Purulia districts in the state of West Bengal. DVC will produce 11,000 MWatt Of power by 2012.

Below are the details of various dams , plants of the Damoday Valley Project...


Maithon Hydel Power Plant


Maithon Dam

Maithon Hydel Power Station is located on the river Barakar about 12.9 km above its confluence with the Damodar near the border of Dhanbad and Burdwan districts of the states of Jharkhand and West Bengal respectively. The unique feature of this Hydel Power Station is that it is located underground in the left bank of the river and is the first of its kind in India. The Power Station has a total generating capacity of 60 MW with 3 units of 20 MW each.

Maithon Gas Turbine Station

Maithon Gas Turbine Station was commissioned at Maithon in 1989. The station has an installed capacity of 82.5 MW with three units each of 27.5 MW capacity. The Gas Turbine Generator has been designed to operate as single unit system on intermittent cycle. These are of simple axial flow type having a single shaft connected to generator with reduction gearbox. The gas turbine is of self-contained modular form having the inherent advantage of quick start-up facility to meet system peak demand under adverse system conditions and also for black start after system failure. High speed diesel is used for starting and stopping the operation while Naptha is used for running the unit.

To whom it may concern:
I was involuntarily 'unsubscribed' from your site. Since I am the first Chief DVC Engineer's grand daughter (who lived with him in Maithon,) I thought for sure information I had concerning the dams in that area would be helpful. Sorry to have bothered you. Andrea

I quote from above " The one at Maithon was India's first underground hydro-electric power station." My grandfather, Andrew M. Komora, was the first chief engineer for Maithon Dam, Konar Dam, etc. in the 1950s. It is disappointing that he was not given credit for his hard work in your article. He was honored that our home in Maithon was named the A.M. Komora House. I lived in that home until ten years old, as I was raised by Andrew and Lucille Komora. I am interested in what my old home looks like today. Andrea
