OVERVIEW OF THE PROJECT

The development of power potential of river Punatsangchhu remained under consideration of the Royal Government of Bhutan (RGoB) for quite some time. In Punatsangchhu basin, seventeen hydro power projects with total capacity of 8,035 MW had been identified in the Power System Master Plan (PSMP) of Bhutan in 1993. Punatsangchhu-I and Punatsangchhu-II were selected for the formulation of PSMP-2003. Punatsangchhu-I is the first Project taken up under the 10,000 MW  by 2020 initiative taken in May 2008 by the Royal Government of Bhutan (RGoB) and the Government of India (GoI). The other successfully implemented prestigious and mutually beneficial friendship ventures are Chukha HEP (336 MW), Kurichu HEP (60 MW) and Tala HEP (1,020 MW).

The 1,200 MW Punatsangchhu-I Hydroelectric project is presently the largest hydropower project under construction in the Himalayan Kingdom of Bhutan. The project is an environment-friendly, run-of-the river scheme located on the left bank of the Punatsangchhu river in Wangduephodrang Dzongkhag. The project will utilize 357 m head available in a stretch of about 11 km along the river. The project site along the left bank is easily accessible by the Wangdue-Tsirang highway on the right bank. With various project components  located between 7 km and 17 km downstream of Wangdue Bridge, the Dam site is about 80 km from Thimphu along the highway. Paro, the nearest airport is about 110 km away. The nearest railway station is at Hasimara (West Bengal, India) on Siliguri-Alipurduar Broad Gauge line of NEF Railway. The project area can also be approached from Bagdogra Airport (near Siliguri, West Bengal, India) via Phuentsholing- Wangdue Highway (about 425 km) and also via, Gelephu-Tsirang-Wangdue highway.

PROJECT IMPLEMENTATION

The Bilateral Agreement between the Royal Government of Bhutan (RGoB) and Government of Republic of India (GoI) for implementation of the (1,095 MW latter revised to 1,200 MW), Punatsangchhu-I Hydroelectric project was signed  on July 28, 2007  by H.E. Lyonpo Khandu Wangchuk, Hon’ble Minister for Economic Affairs on behalf of the Royal Government of Bhutan (RGoB) and H.E. Shri S.M.

The project was sanctioned at a cost of INR/Nu. 35,148 million and is funded by the Government of India (GoI): 40% Grant and 60% Loan at 10% annual interest, repayable in 30 equated semi-annual installments commencing one year after the mean date of operation. The Government of India (GoI) shall be providing additional funds, as mutually determined, for the completion of the project, in the same proportion and on the same terms and conditions. All the surplus power from the project will be exported to India.
