CHAMERA-III
Chamera-III Power Station (3x77 MW) is a run of the river scheme with small pondage to harness the hydro power potential of river Ravi. It is located in Chamba district of Himachal Pradesh. The project comprises of a 64 m high, 73 m long concrete gravity dam with 6.5 m dia., 15.97 Km long head race tunnel. The underground power house with installed capacity of 231 MW houses 3 units of 77 MW capacity each designed to operate under the net rated head of 200 m and designed to generate 1108.17 million units in a 90% dependable year with 95% machine Availability. All the three generating units of the power station were commissioned in the month of June-2012. The beneficiary states/UTs of this power station are Uttarakhand, UP, Delhi, HP, Haryana, J&K, Punjab, Rajasthan and Chandigarh. The nearest rail head is Pathankot and nearest airport is Jammu. With the construction of the project, the area has also been benefitted by development of infrastructure, education, medical facilities and employment avenues.
