Omkareshwar Power Station
Omkareshwar Power Station is a multipurpose project, which offers opportunity of power generation & irrigation on both the banks of river Narmada in districts Khandwa, Khargone & Dhar of Madhya Pradesh. The project is situated 80 km from Indore and 40 km down stream of Indira Sagar Project. The Cabinet Committee on Economic Affairs (CCEA) sanctioned the Project with an estimated cost of Rs.2224.73 Crores (Nov. 2002 Price Level) and total gestation period of 5 years. Omkareswar project was cleared by CCEA on 29.03.2003. The foundation stone of this project was laid by the then hon’ble Prime Minister of India Shri Atal Bihari Vajpayee on 30.08.2003 All the eight units of this project have started generation power from Nov. 2007 well ahead of sanctioned schedule. Due to early commissioning of units, substantial amount of savings has been made in the actual completion cost. Total installed capacity of the Omkareswar Project is 520 Megawatt (8x65). The project will generate 1167 Million Units energy, annually. Total catchments area at the proposed dame site is 64880 Sq. km, out of which 3238 Sq. is Downstream of Indira Sagar Power Station. The Project consists of 949 m long Concrete Gravity Dam with maximum height of 53 m from the deepest bed level across the river Narmada. A Central Ogee-type spillway 570 m long with crest level EL 179.6 m has been provided to pass the Probable Maximum Flood of 882315 cumecs. 23 No. Radial gates of size 20m x 18m have been erected for regulation of floodwater. 8 penstocks have been erected in 208 m long Power Dam with maximum height of 49m. 10 Nos. sluice gates of size 3.5m x 4.5m at the level of 173.5 m were provided for diversion purpose which has now been plugged. The surface Power House (202m x 23m x 53m) of the Project is within the body of Dam on the right bank of Narmada consisting of 8 Units of 65 MW capacity each with conventional Francis Type Turbines. Water is carried to the Turbines through 8 no. Penstocks of 7.66 m diameter each. After generation water is discharged back in the river through 145 m long Tail Race Channel. The Omkareshwar Power Station generated 1,264.00 MU against the target of 1,184.00 MU for the Financial Year 2012-13.
