Khimti I Hydropower Project (60 MW)

Khimti I Hydropower Project (60 MW)

This project has an installed capacity of 60 MW and uses a gross head of 684 m through a total waterway length of 10 km at the rated flow of 10.75 m3/s, producting 350 GWh units of energy annually.

Construction works for the project was started in1993, although the work gained momentum only after financial closure in June 1996. The project was completed in May 2000, ahead of schedule despite tremendous geological, logistical and other local problems.

The environmental impact of the project is very minor and the project has been praised for its excellent compliance with strict health, safety and environmental standards. Cooperation of workforce during construction of the project was also extremely good throughout the project period.
