About

Devighat Hydropower Station was founded in 1984 and is currently located at Bidur Municipality in Nuwakot, Nepal. It is considered a cascade project of Trishuli Hydropower. Trishuli river is one of the longest rivers which rises from Himalaya Tibet. Since it is a speedy river, it can generate a large amount of energy. Trishuli Hydropower itself was funded by the Indian Government and generated 21000 KW of electricity. Since the Trishuli river has higher possibilities to generate extra units of electricity, it became the primary source of the river for the Devighat Hydropower station. This project was manipulated by the governments of India and Nepal with the project costing NPR 750 million. The plant was underperforming after the completion of construction. Therefore, in 2011 these two countries started their rehabilitation to achieve efficiency of the plant. Finally, Hydropower generated 14.1 MW of electricity in a year. There is still some underperformance during the dry season because the Trishuli river’s flows get slower during that time. Lower water speeds can not generate electricity as it is capable. There are three units and one of them used to be problematic until 2011 rehabilitation. After all, all three units are in normal condition and performing well. So then, Hydropower capacity increased by 41.76% from 2010 to 2012.
