Narrative Description of the Project:

The Budhi Gandaki Hydroelectric Project is a storage type project with installed capacity of 1200 MW (6 units of each 200 MW) with operating rated head of 200m, total storage volume of 4500 million m3 and  annual energy generation of 3383 GWh in average year. Budhi Gandaki Hydropower Project is located on the Budhi Gandaki River, approximately 2km from its confluence with Trishuli River at Benighat along the Prithivi Highway and about 80km from Kathmandu. The Proposed Dam is a double curvature concrete arc dam of 263m high and 760m long with six no. of  intake facility to withdraw design discharge of 672m3/s each intake withdraws 112m3/s.). A short headrace tunnel and penstock pipe linking the intake to the powerhouse.

The surface power house is located on the left bank of Budhi Gandaki River approximately 500m downstream of dam. The power is evacuated from switchyard through 400kV double circuit transmission line to proposed 400kV Hetauda Substation and proposed Naubise substation.
