Location

It is located in Kalimpong district, West Bengal, about 350 meters above the confluence of the Kalijora river Teesta River and in the 1.5 kilometer kiln of Teesta Bridge near Teesta Bazar village. 18.3 km downstream from the Teesta bridge near at Tista Bazar village. It is near Kalijhora, (see map alongside).

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.

Mica Dam Dam in Mica Creek, British Columbia, Canada

Mica Dam, a hydroelectric embankment dam spanning the Columbia River 135 kilometres north of Revelstoke, British Columbia, Canada, was built as one of three Canadian projects under the terms of the 1964 Columbia River Treaty and is operated by BC Hydro. Completed in 1973 under the terms of the treaty, the Mica powerhouse had an original generating capacity of 1,805 megawatts (MW). Mica Dam, named after the nearby settlement of Mica Creek and its associated stream, in turn named after the abundance of mica minerals in the area, is one of the largest earthfill dams in the world. The reservoir for the dam is Kinbasket Lake, which was created when the dam was built. Water from the dam flows south directly into Revelstoke Lake, the reservoir for the Revelstoke Dam. Mica Dam is the tallest dam in Canada and second tallest in North America after the Chicoasén Dam in Mexico and it is the farthest upstream dam on the Columbia River. The dam's underground powerhouse was the second largest in the world at the time of its construction, and was the first 500 kV installation of sulphur hexafluoride (SF6) insulated switchgear in the world.
