Nepal : private-sector approach to implementing micro-hydropower schemes, a case study

First, the history of hydropower development in Nepal is reviewed, and the selection of turbine type, the development of turbine technical design, and the design of a typical mill installation are described. After a brief analysis of the composition and functions of the installation team, steps to be taken in installing a mill in Butwal are set forth, including: site selection and layout; installation price quotation; design, fabrication, and delivery; actual installation; design modifications; and costs. Finally, the use of mechanical heat generators and heat storage cookers to expand hydropower use, the development of a mill lighting system using electricity generated by hydropower, and two cooperative projects involving UMN and villagers are assessed. It is concluded that the Butwal project has been successful because income-generating end-uses were initially incorporated into the project, because small hydropower has proven less costly to operate and maintain than diesel plants, and because of the long-term, in-country effort of UMN staff.
