Nathpa Dam

Nathpa Jhakri Hydroelectric Power Project, has run up all six 250MW units of the Nathpa Jhakri Hydroelectric Power project. Four of the units have already been commissioned, and the last two (Units #1 and 2) began working in March 2004, four months ahead of schedule.

As a whole, Nathpa Jhakri boasts the largest and longest headrace tunnel, largest desilting chambers, deepest and largest surge shaft, and the largest underground power complex. The project has added 1,500MW capacity to the Indian Northern Grid since the first unit was commissioned in October 2003. The Union power ministry is reportedly treating this as a benchmark for future hydroelectric projects.
