The project

The project consists of a 45 m high dam with 4 penstocks of 45 m length and 7 m diameter each. The surface power house with installed capacity of 160 MW houses 4 units of 40 MW capacity each designed to operate under the net rated head of 25.05 M and designed to generate 720 million units in a 90% dependable year with 95% machine availability. Unit I, II, III and IV were commissioned in the month of February, March, July and August 2016^[1][3] respectively. The state of West Bengal is the sole beneficiary of this power station. With the construction of the project the area is also benefited by development infrastructure, education, medical facilities and employment avenues.
