The Mailung Khola Hydropower Project, located in the Nuwakot district within the Central Development Region of Nepal, is a 5 MW run-of-river scheme harnessing the Tadi Khola. The project's geographical coordinates range from approximately 27º 55' 36" N to 27º 55' 00" N latitude and 85º 21' 08" E to 85º 19' 15" E longitude. The intake site is situated in Tadi Rural Municipality-4, while the powerhouse site is in Tadi Rural Municipality-3. The scheme employs a boulder-riprap with RCC cutoffs weir type, with a weir crest level and static water level at 798.50 masl. The gross head is 74.12 m, providing a net head of 65.60 m. The design discharge is 8.91 m3/sec, supporting an installed capacity of 5 MW. The project exhibits a robust hydrological profile, covering a catchment area of 247 km2, a design discharge of 8.91 m3/s, and a design flood discharge matching the 1 in 100-year flood event. The intake structure features side intakes with two openings of 3.2 m (B) × 2.4 m (H) and an invert level of 795.60 masl. The sluiceway comprises two openings sized at 2.8 m (B) × 2.5 m (H) with an invert level of 794.00 masl. The desanding basin includes two chambers with a parallel section dimension of 44 m × 5.0 m × 6.1 m and a forebay sized at 10.0 m (L) × 6.4 m (Avg. B) × 8.25 m (H). A 270.31 m RCC culvert with a clear opening of 2.0 m × 2.0 m is part of the infrastructure, along with a penstock measuring 1770.00 m in length, 1.9 m internal diameter, and encased with shotcreting. The powerhouse is a surface type with dimensions of 25.80 m × 16.20 m × 16.20 m, and it accommodates two horizontal axis Francis turbines. These turbines, with a rated flow of 4.45 m3/s, operate at a rated net head of 65.84 m, producing a total rated power of 2.621 kW at 750 rpm. The runway speed is set at 1246.80 rpm, ensuring efficient energy generation from the Tadi Khola.
