About

The Hewa Khola Hydropower Project is a 14.9 MW run-of-river hydropower plant located in Panchthar District, Eastern Development Region, Nepal. The project utilizes water from the Hewa Khola river and features key infrastructure including a low-height boulder-lined weir with concrete cut-off walls, a gated side orifice intake with trash racks, and a nearly 4 km long inverted D-shaped headrace tunnel. It has two Francis turbines, each rated at 7.5 MW, and synchronous generators with step-up transformers feeding power into a 132 kV, 5 km transmission line connected to the Panchthar substation. The plant also provides water for irrigation and drinking purposes through a 3.7 km canal system. The project was completed following a feasibility study finalized in 2011 and has a total project cost of NPR 2.235 billion. Its design flow is 8.12 m³/s, with an annual energy generation estimate of about 84.76 GWh, divided between wet and dry season outputs. The plant's governance includes electronic flow governors and modern overhead crane facilities, indicating an emphasis on operational efficiency and reliability.
