Orto-Tokoy Hydropower Plant in Kyrgyzstan Enters Final Construction Phase

The launch of the Orto-Tokoy hydropower plant in Kyrgyzstan is scheduled for this year. Construction is currently entering its final stage, with contractors beginning the installation of primary equipment and the preparation of grid infrastructure.

The majority of the underground work is already complete. Construction crews have finished excavating the 950-meter diversion tunnel. A 602-meter section has been fitted with a 5.4-meter diameter concrete lining, while the remaining 348 meters are protected by a metal casing. The monolithic water intake shaft has also been concreted, and a building frame is being erected over it to house the lifting mechanism for the operational gate.

Assembly of the first hydraulic unit is underway in the machine hall of the facility. Engineers are aligning the embedded components for the generator stator and the lower bracket, alongside installing the guide vane and the turbine runner. Inside the building, technical water supply pipelines and water filtration systems are being mounted, and the thermal envelope is being closed by sealing the windows.

Outside the machine hall, workers are reinforcing the right bank of the tailrace canal with gabion structures to prevent erosion. A power distribution scheme is being developed concurrently. Construction teams are laying access roads to facilitate the delivery of heavy machinery and excavating pits for the foundation supports of a future 110 kV high-voltage power line – a network addition that will link the new hydropower plant to the energy grid.
