The Punatsangchhu-II project is a run-of-the-river facility located in Bhutan's Wangdue Phodrang district. It was funded primarily by the Government of India with 30% as grant and 70% as loan. It was supported by Indian engineering consultancies, Water and Power Consultancy Services for engineering and design and the National Institute of Rock Mechanics for modeling and geotechnical engineering services. Construction of the project began in December 2010.
