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.

Vyasi Power Plant (Installed Capacity : 2X60 MW)

Vyasi Power Plant (2 X 60MW=120 MW)

Vyasi Hydro Power Station (2X60MW) constructed at Hathiyari, is a run of river with pondage scheme at Juddo. Vyasi Hydroelectric Project envisages the utilization of head available in the river Yamuna. In Vyasi Hydro Power Station, water is diverted through a Dam at village Juddo, five Km upside of Hathiyari Village and nearly 63 Km from Dehradun. The Dam is designed to divert 119.78 Cumecs of water into a Head Race Tunnel (HRT) of diameter 7.0 m, length 2.7 km to generate electricity through Vyasi Hydro Power Station.

The Vyasi Hydro Power Station comprises of two hydro power generating units of 60 MW each. The generator is powered by Francis turbines of 61.230 MW rated capacity. The rated flow through each turbine is 59.89 Cumecs and is discharged to a common tail race channel.

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.
