OVERVIEW OF THE PROJECT
In Punatsangchhu basin, there are seventeen Hydro Power projects with total capacity of 8,035 MW identified in the Power System Master Plan (PSMP) of Bhutan-1993. Two projects namely, Punatsangchhu-I and Punatsangchhu-II were selected for the formulation of PSMP-2003. Punatsangchhu-I (1,200 MW) & Punatsangchhu-II (1,020 MW) are the two first projects taken up for development towards the result of the 10,000 MW by 2020, initiative taken by Royal Government of Bhutan (RGoB) and Government of India (GoI) in May 2008.
The project is located on the right bank of Punatsangchhu river along the Wangdue-Tsirang highway between 20 km and 35 km downstream of Wangdue Bridge. The Dam site is about 94 km from Thimphu along the highway. Paro, the nearest airport is about 125 km away. The nearest railway station is at Hasimara on Siliguri-Alipurduar Broad Gauge line of NEF Railway. The project area is also accessible from Bagdogra Airport near Siliguri and via Phuentsholing-Semtokha (near Thimphu) – Dochula (about 440 km). The project area can also be approached from Gelephu, a border town in South Central Bhutan.
