Title: Indian showcase project for minimally invasive and responsible construction of a hydro-electric power plant
The Nathpa Jhakri Hydro-Electric Project, started in 1993, became the largest hydro-electric plant in India. The system consists of a 60.6 meter high concrete retaining wall, a subterranean desilting complex, and a 27.5 km long headrace tunnel, one of the longest in the world, and a 300 meter deep surge shaft with a subterranean machine complex. Since 2004 the six 250 MW turbines of the system at the foot of the Himalayas deliver a total of 1500 MW at peak times to the grid in the north of India. Annually 7000 GWh of electricity are generated. During realization, special attention was paid to minimizing ecological impact. The living conditions of 480 families who lived in the area were improved in an exemplary resettlement project, new income sources arose from the subsidization of agriculture, and infrastructure improvements were made for the local school.
