Abstract Nepal's hydropower sector faces numerous challenges due to sediment erosion resulting from the country's steep terrain, fragile geological structure, and intense monsoon rainfall. These elements, along with off-design operational dif<iculties, cause hydraulic components to deteriorate, which lowers power plants' safety and efficiency. Nepal's main energy source is hydropower, so enhancing repair and maintenance procedures is crucial to ensuring dependable operations and preserving efficiency. In order to maintain Nepal's energy infrastructure and economic growth, this research looks at the hydropower sector's capacity for repair and maintenance. To assess the present status of maintenance procedures, labour competencies, and technical capabilities needed to enhance repair and maintenance services, the study looks into the current trend. The study points out an urgent need for advanced maintenance strategies to address the increasing complexity of turbine technologies and evolving regulatory requirements. It also identifies major gaps in the skills of the local workforce and the availability of necessary technological resources. These findings point to the importance of targeted investments in workforce training and infrastructure development to enhance repair and maintenance capacities. Strengthening these capacities is essential to prolong the operational life of hydropower plants and improve their overall performance.
