The 510MW Zangmu hydroelectric project on the Brahmaputra River in Tibet has become operational following the launch of one its six 85MW units yesterday.

Claimed to be the world’s highest-altitude hydro project, and the largest in Tibet, the project is being developed by a Tibetan subsidiary of China Huaneng Group. Construction of the project was launched in 2007 and it is expected to become fully operational by August 2015.

The run-of-river project has been subject to some controversy, with India concerned about potential effects downstream, including flash floods.
