Introduction

Rudi Khola - B Hydroelectric Project is a run-of-River (RoR) type project and is proposed to be developed by Bindhyabasini Hydropower Development Company Ltd., with an installed capacity of 6.6 MW with 300 m net head and 2.5 m3/s (cumec) design discharge at Q40%. This project is being developed in tandem with Rudi Khola - A Hydroelectric Project (8.8 MW) in cascade system.

 

Project Location and Accessibility

Major components of Rudi Khola - B Hydroelectric Project are located in Kwholasothar Rural Municipality, Province No.4 (previously Pasgaun VDC, Lamjung district). Geographical coordinate of the project area is located between latitudes 28°16’20" N and 28°17’50” N and longitudes 84°11’00” E and 84°13’00” E.

The project site is accessible from Damauli via Rambazar (45 km) and also from Pokhara via Mungribesi. New access track along the 8 km long, Rudi-A alignment has been constructed by the project to reach Rudi-B.

 

Project Description

The main components of the projects are collection headworks atTago Khola, Karbu Khola, Kaiyu Khola, and Ligur Khola; collection headpond, gravel trap, desander, headrace pipeline, surge tank, penstock, powerhouse, tailrace, switchyard, 33kV transmission line and interconnection facilities.

The individual headworks of Rudi-B are located 200 m upstream from the confluence of the rivers forming Rudi Khola, which are Tago, Karbu, Kaiyu, and Ligur. There will be common desander at left bank of Rudi Khola and the conveyance structure is headrace pipeline of 2.7 km long, 1.30 m diameter to the Surge tank of the project., which shall lead to 600 m long penstock which supplies discharge to powerhouse having two units of Pelton turbines. The power from project shall be transmitted to Mijure Danda substation by a 3.7 km long, 33 kV, double-circuit transmission line.

 

Project Output

The total energy generation is 33.2 GWh, with dry energy comprising of 5.1 GWh (15%) and wet energy contributing 28.1 GWh (85%).
