From Site Survey To Commissioning
Visual documentation of key construction, electromechanical, and commissioning milestones.
The Tinau Run-of-River Hydropower Project is a 25 MW peaking facility developed on the Tinau River in Palpa District, supplying clean power to the Integrated Nepal Power System (INPS). National Tech Hydro & Electric served as the engineering, procurement, and commissioning partner across all civil, mechanical, and electrical scopes.
From initial feasibility through hydraulic modeling, headworks design, penstock fabrication, and turbine-generator installation, our team coordinated more than 35 specialists and 14 vendor partners to deliver the project on schedule and within budget.
The project required careful hydraulic and geotechnical analysis to balance environmental flow obligations with peak-hour generation. Our team performed CFD-based intake modeling, conducted three rounds of geotechnical surveys, and worked closely with the Department of Electricity Development to secure all required approvals well in advance of construction milestones.
All electrical works — switchyard, transformers, protection relays, control systems, and grid synchronization — were executed in-house under NEA's interconnection standards, ensuring seamless commissioning and first synchronization on the planned date.
