Impact of Variation in Climatic Parameters on Hydropower Generation: A Case of Super Dordi Hydropower Project Kha in Nepal

Abstract

Nepal has substantial potential to generate electricity through hydropower projects. Most of the hydropower projects in Nepal are Run-off-River (ROR) types. Significant seasonal variation can be pronounced on its river basins resulting in higher streamflow & higher hydropower generation during the wet/summer season and just reverse scenario in case of the dry/winter season. Thus, ROR-type hydropower in Nepal is more susceptible to Climate Change. This study assesses the impact of variation in climatic parameters on the power generation of Super Dordi Hydropower Project Kha and streamflow of Dordi River by implementing WEAP model using the meteorological and hydrological data from 1976 to 2004 under Reference & Climatic Scenarios. Super Dordi Hydropower Project Kha is located in Lamjung District in the Western Development Region of Nepal. It is a Run-off-River type of project being developed by Peoples Hydropower Company Ltd. The Geographical coordinate of the project area lies between Longitudes 84o34’15” E and 84o31’00” E, Latitudes 28o18’50” N and 28o16’20” N.
