Prior to formation of SJVN (NJPC), NJHPS was being executed by Himachal Pradesh State Electricity Board (HPSEB). The generation component of 1500 MW NJHPS was sanctioned in April 1989 for execution by SJVN (NJPC). SJVN (NJPC) officially took over NJHPS on August 01, 1991, following an agreement between GOI and GOHP during July 1991. However, the effective takeover of the NJHPS could result only during February 1992, due to an agitation by the employees of HPSEB. The Major Civil Works of NJHPS were awarded during June – Sep. 1993 and the construction works commenced in early 1994.

Location
Nathpa Jhakri Hydro Power Station – NJHPS, is located in the state of Himachal Pradesh, on the downstream of wangtoo Bridge and derives its name from the names of two villages in the Project vicinity - Nathpa in district Kinnaur and Jhakri in district Shimla - in the interiors of Himachal Pradesh. The Project was conceived as a run-of-river type hydro power development, harnessing hydro-electric potential of the middle reaches of the river Sutlej, one of the principal tributaries of the river Indus, in the south west Himalayas. The Project's Dam has been constructed near village Nathpa and its Power House has been constructed on the left bank of the river Satluj at village Jhakri. The power house site is about 150 km from the nearest railhead (narrow gauge), Shimla. The Project stretches over a length of about 50 kms. from the Dam site to the Power House site, on the Hindustan-Tibet Road (NH-22), which also connects the rail head to the Project.

SJVN abides by its moral responsibility for maintaining a safe environment for all its employees and also those of its contracting agencies. The safety measures adopted encompass the best codes and practices which are disseminated to all the employees for ensuring compliance at all levels.

Safety Measures
Due attention is given to health and safety aspects in working areas and because of all such efforts no untoward accident has been reported since comminissioning of the project. Towards this end, a separate Safety Department is functional at the Project. SJVN had already enrolled as a corporate member of the National Safety Council (NSC) and availed of the pertinent safety related information, manuals and literature from the NSC for educational use and implementation. Safety related training programmes have also been organized in consultation with NSC. Awareness about safety aspects within and outside the plant areas of the Project are also imparted by the use of audio-visual methods, including, banners, posters, etc. Safety related quizzes and other competitive events are also organized from time to time.
