The Ichari Dam is a concrete gravity dam on the Tons River 13 km (8 mi) north of Dakpathar in Uttarakhand, India. The primary purpose of the dam is hydroelectric power production and it is a run-of-the-river-type. The dam diverts water to the Chibro Power Station (240 MW) which when returned to the Tons River is then fed to the Khodri Power Station (120 MW).
Chibro Power Plant
Adjacent to the dam and on its left bank, water is diverted into a 6.2 km (4 mi) head-race tunnel which leads south to the underground power station at 30°33′23″N 77°47′53″E / 30.55639°N 77.79806°E. There, the water powers four 60 MW Francis turbine-generators. The design hydraulic head of the station is 110 m (361 ft) and its design discharge is 200 m3/s (7,063 cu ft/s). The plant was commissioned in 1975 and was the first power plant built underground in Northern India.[1]
Khodri Power Plant
Water discharged from the Chibro Power Plant is returned into the Tons River just 100 m (328 ft) upstream of the intake for the Khodri Power Station. Water enters the intake and then travels south down a 7.5 km (5 mi) head-race tunnel which leads to the power station on the Yamuna River at 30°30′30″N 77°47′59″E / 30.50833°N 77.79972°E. There, the water powers four 30 MW Francis turbine-generators before being discharged into a tail-race channel behind the Dakpathar Barrage. The design hydraulic head of the station is 57.9 m (190 ft) and its design discharge is 200 m3/s (7,063 cu ft/s). The plant was commissioned in January 1984.[2]
