The progress in the raised weir area and undersluice is on progress. The project continues to progress steadily across all major components. The elevation gains at the weir, completion of foundational elements at the undersluice, and ongoing earthworks in the pondage area indicate a positive trend toward achieving project milestones.
During the reporting period, notable progress was achieved at the undersluice. Raft concreting has been completed, with rebar works advancing up to 6 meters. Vertical and radial gate embedments are installed, and the left and right walls—measuring 4 meters and 3 meters from the bucket portion—are completed. Backfilling will proceed as the wall height increases, with adjacent rocks being either removed or grouted based on site conditions.

Backfilling will proceed as the wall height increases, with adjacent rocks being either removed or grouted based on site conditions.
In the pondage area, slope cutting and heavy excavation are ongoing along the right bank upstream of the raised weir, spanning approximately 150 meters in length with a slanted height of 27 meters. A structural solution is proposed for this section, involving the construction of an inclined wall with a horizontal beam and boulder packing from an elevation of 2000 meters down to the riverbed. The remaining area is shaped into a gentle slope of 1:3 or 1:4 toward the riverbed.
Headrace pipe (HRP) works are progressing steadily. The alignment is accessible by motorable road, aiding transport and construction. Excavation is ongoing at crossing points, with blasting completed. Pipe laying, concreting of anchor blocks, and support pier works are active along the route. 40 anchor blocks are completed, jacketing is underway, and 4 km of pipe is already laid. Four major crossings for siphons and bridges are under excavation, with designs in progress based on completed topo surveys.
Concreting work up to 6 meters from the crank level (EL.1990.6) has been completed. However, the work is currently on hold, with plans to use pumps from the powerhouse for future concreting activities. The backfilling around the surge tank is already completed. Work Progress: 60% Complete, 40% Remaining.
Excavation from Anchor Block 17 to the concrete casing area upstream of the powerhouse has been completed. A saddle pad is installed in the excavated section to support the penstock pipe. Concrete casing works for the inclined penstock are ongoing upstream of the powerhouse, indicating active construction in that area. Site clearance and preparatory activities for the laying of the penstock pipe are in progress along parts of the penstock alignment. Additionally, bioengineering is proposed for the inclined penstock section to stabilize the soil and prevent erosion.
Civil works at the powerhouse have reached up to the corbel beam level, with rebar installation currently underway. The machine floor slab is partially left open as per the EM contractor’s specifications for embedding turbine and generator components. The turbine casing is expected to arrive soon for later installation. Additionally, the cooling chamber is almost complete, pending only the top slab.

The Isuwa Khola Hydropower Project is a 97.2 MW Peaking Run-of-River (PRoR) scheme located in the Makalu Rural Municipality of Sankhuwasabha District, Koshi Zone, Eastern Region of Nepal. It is designed to contribute significantly to Nepal's national electricity network.
The project has an installed capacity of 97.2 MW.
The project aims to supply 674.30 GWh of annual energy to the Nepal electricity network.
As of June 2025, the overall construction progress of the Isuwa Khola Hydropower Project is 65%.
The Proposed Extended Commercial Operation Date (RCOD) for the project is February 13, 2027. The original Commercial Operation Date (COD) as per the Power Purchase Agreement (PPA) was October 13, 2024.
Key civil works include a raised weir (50m x 37m), a side intake with two orifices, a 6911.53m long headrace pipe, a circular surge tank, a 2500m long penstock, and a surface powerhouse (115m x 20m).
