Kaliganga-I (Installed Capacity : 2 x 2 MW)

Kaliganga-I (2 x 2 MW) Small Hydro Project

The Kaliganga-I Small Hydro Project is located on the river Kaliganga between the bridge over Kaliganga on Jaltala to Chilan road and Kotimaheshwari temple located just downstream of the confluence with river Mandaniganga. The project is located in the Ukhimath tehsil of Rudraprayag district of Uttarakhand. It is proposed to have an installed capacity of 4000 kW with two (02) units of 2000 kW each. The project has been conceived as a run of the river project without any storage.

The stream has a catchment area of 69.55 sq.km extending from a height of about 5000 meter above MSL up to trench weir located at an elevation of 1670.55 m near the village Jaltala just below the bridge on the Jaltala–Chillan bridle path.

The Power Plant to have two (02) turbine generating units each of 2000 kW output at generator terminals.

The levelized cost of generation is Rs 4.53 for 35 years considering discount factor of 10%. Benefit cost ratio and internal rate of return of the project are 1.03 & 10.39%, respectively.

Galogi (Installed Capacity : 1 X 3 MW)

Galogi Power Plant (1 X 3= 3 MW)

Galogi Power Station is located 22km away from the state capital Dehradun. Galogihydel power station was among the earliest hydropower plants commissioned by the British in 1907. Three more plants were commissioned at the same time at Chamba in Himachal Pradesh, Darjeeling in West Bengal and Mysore in Karnataka. Galogi was the first hydel power station to generate electricity and light up houses on November 9, 1912. Some of these records go as far back as December 19, 1912. While the other three plants have stopped functioning long back, Galogi continues to be in service, nearly 106 years later. It still lights up homes in Mussoorie's Barlowganj and Doon valley's Anarwala area in district Dehradun.

Chibro (Installed Capacity : 4X60 MW)

Chibro Power Plant (4 X 60=240 MW)

Chibro HEP is a Run-of-River scheme with an underground Power Station. It was the first underground Power Station in North India and was commissioned in year 1975. The Power station draws water from Ichari dam located on the river Tons, one of the major tributary of river Yamuna.

Chibro Power station is a unique engineering marvel in the country and was the first experience in carrying out tunneling in Himalayan Thrust Zones, which was a challenge due to varied rock structure and throws up unexpected challenges in tunneling efforts. The water from Ichari Dam is fed into the Power station through a 6.2 Km long Head Race Tunnel (HRT). The Power Station comprising of 4 units of 60 MW each Francis turbines of 84,000 HP output, is housed in a rock cover with the major challenge of maintaining fresh air and safety measures due to constraint of space. Design head of HEP is 110m.
