The foundation stone of this project was laid by the then Hon’ble Prime Minister of India Late Smt. Indira Gandhi on 23.10.1984. It is a multipurpose project on the river Narmada with installed capacity of 1000 Megawatt (8X125). It will generate 2698 MUs energy, annually. The project will irrigate 2.70 lakh ha land annually. As per CCEA sanction the project cost is Rs. 4355.57 Crores (Sept. 2000 Price Level). Due to early commissioning of units, substantial amount of savings has been made in the actual completion cost. The project consists of Concrete gravity dam of length 653 meter at top with maximum height (above deepest foundation level) of 92 meter. The dam involved pouring of 14.00 lacs cubic meter concrete. It consists of 12 main spillway blocks with effective width of 20 m each. 20 no. radial gates of size 20 m X 17 m have been erected for regulation of flood water. The surface Power House is situated on the right bank of the river, with Machine hall (202 meter long, 23 meter wide, 53 meter high), service bay (42 meter long, 23 meter wide, 24 meter high) and transformer yard (202 meter long, 20 meter wide) to house 8 Nos. Francis type turbines of 125 MW each. The water conductor system consists of one Head Race Channel of length 530 meter, width 75 meter and depth 50 meter with water carrying capacity of 2200 cumecs. Water enter into turbine fron intake structure by 8 Nos. Penstock of 8 meter diameter and 157 meter length each. Water flow capacity of each Penstock is 275 cumecs. After power generation water is discharged back into river Narmada through 850 m long Tail Race Channel. During the financial year 2012-13, 2,896.49 Million units of power generated from Indira Sagar Power Station against the target of 2,200.00 MU.
