The Nathpa Jhakri Dam is a concrete gravity dam on the Sutlej river in Rampur Bushahr, Shimla district, Himachal Pradesh, India. The primary purpose of the dam is hydroelectric power production and it supplies a 1,500 megawatts (2,000,000 hp) underground power station with water. Before reaching the power station, water is diverted through a 27.4 km (17 mi) headrace tunnel. Construction on the project began in 1993 and it was complete in 2004. The last two of the 250 megawatts (340,000 hp) Francis turbine-generators went online in March 2004. It is owned by SJVN.
