Tala Hydroelectricity project is the biggest hydroelectric joint project between India and Bhutan so far, generating 4865 GWh/yr. Tala is located in Chukha Dzongkhag in western Bhutan, a small constitutional monarchy in the Himalayas.[1] It is located on the Wongchu River and, and is at a height of 860 metres (2,820 ft).
The dam is 92 m high and feeds a 22 km-long headrace tunnel. An underground power house in Tala village has six 170 MW generators. Three 440 kV transmission lines stretch to the Indian border, since the power is being entirely supplied to India. Bhutan aims to export 10,000 MW of power by the year 2020. Dam building started in 1998 and the project was commissioned in 2007.[1]
