Solu Khola (Dudhkoshi) Hydroelectric Project (SKDKHEP) is an 86 MW Run Of River (RoR) type of project located at Solududhkunda Municipality & Thulung Dudh Koshi Gaupalika (Former Tingla, Kangel & Panchan VDCs) of Solukhumbu District, Sagarmatha Zone, Nepal. The project area is about 130 km (aerial) east of Kathmandu and is situated within longitude 86°37’35” to 86°41’15” East and latitude 27°21’53” to 27°25’15” North. The project utilizes a design discharge of 17.05m³/s from Solu Khola and the elevation difference between the proposed intake at Solu Khola and powerhouse at Dudhkoshi River for power generation.

The proposed headworks is located at Gairigaun village of Solududhkunda Municipality, about 600 m downstream of the suspension bridge over Solu Khola (River) at Sanghutar. Surface settling basin, headrace tunnel,  pressure shaft tunnel passes along different places of Thulung Dudh Koshi Gaupalika. The proposed powerhouse, switchyard and tailrace canal all are located near Maikubesi of Thulung Dudh Koshi Gaupalika, on the right bank of Dudh Koshi River, about 1 km upstream of the suspension bridge over Dudh Koshi River at Jaleshwor Mahadev.and 3.5km upstream of the confluence of Solu Khola and Dudh Koshi River.

The project consists of a simple weir with undersluice, side intake, gravel trap, approach channel, an desalting basin, headrace tunnel, surge shaft, inclined pressure shaft and horizontal penstock tunnel, surface powerhouse and a tailrace canal.
