The project

The project consists of a 32 m high dam with 4 penstocks of 44 m length and 7 m diameter each. The surface power house with installed capacity of 132 MW houses 4 units of 33 MW capacity each designed to operate under the net rated head of 21.34 M and designed to generate 594.07 million units in a 90% dependable year with 95% machine availability. Unit I & II were commissioned in the month of January 2013 and Unit III & IV in the month of February and March 2013 respectively.^[3] 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.
