Nameplate capacity of the powerplant

The Sardar Sarovar Project provides two power houses: 1,200 MW River Bed Power House and 250 MW Canal Head Power House. The River Bed Power House is an under ground power house stationed on the right bank of the river, located about 165 meters downstream of the dam. It has six number of Francis type reversible turbine generators each of 200 MW installed capacity. The Canal Head Power House is a surface power station in a saddle dam on right bank of the reservoir housing five units each of 50 MW.


The Sardar Sarovar Project on the Narmada River has sparked worldwide controversy. The project is designed to bring irrigation to almost 2 million hectares of arid land, in what it would be the largest such system in the world. It promises drinking water for 30 million people in drought-prone areas, and electricity for agriculture, cities, and industry. But it threatens the livelihoods of more than 140,000 people in the areas to be flooded by the Sardar Sarovar dam and to be affected by the building of canals. And it may have negative environmental consequences.
