The Nathpa Jhakri Dam is a concrete gravity dam on the Sutlej river in Himachal Pradesh, India. The primary purpose of the dam is hydroelectric power production and it supplies a underground power station with water. Before reaching the power station, water is diverted through a 27.40NaN0 headrace tunnel. Construction on the project began in 1993 and it was complete in 2004. The last two of the Francis turbine-generators went online in March 2004. It is owned by SJVN.[3]
The scheduling and despatch of the Nathpa Jhakri Hydro Power plant is done by Northern Regional Load Despatch Centre which is the apex body to ensure the integrated operation of the power system grid in the Northern region and comes under Power System Operation Corporation Limited (POSOCO).
