Kyrgyzstan’s Ortho-Tokoy Hydroelectric Project Enters Equipment Assembly Phase
Construction of the Ortho-Tokoy hydroelectric power plant (HPP) in Kyrgyzstan has progressed to the installation of main generating equipment and associated infrastructure. Work on the 21-megawatt (MW) facility is proceeding on schedule, with current efforts focused on constructing a high-voltage transmission line and preparing key hydraulic structures.
To integrate the new HPP into the regional power grid, a 110-kilovolt (kV) transmission line is being constructed. Workers have completed foundation work at primary sites along the route and erected 18 of the planned 26 intermediate support towers. Teams are continuing to assemble anchor structures, install grounding loops, and prepare access roads to accommodate heavy construction machinery.
In parallel, excavation of the 950-meter diversion tunnel has been completed. Current operations inside the tunnel involve installing metal lining and injecting concrete grout to reinforce the structure. The above-ground portion of the facility has also progressed – workers completed the construction of the technical building over the water intake shaft.
Inside the Ortho-Tokoy HPP powerhouse, technicians have commenced the assembly and commissioning of generating equipment. Auxiliary transformers have been installed, and the rotor for the second hydro-unit has been aligned. Teams are also installing auxiliary systems inside and outside the building, laying cable lines, configuring relay protection and automation systems, and carrying out interior finishing.
On the adjacent grounds, work is underway on a 110 kV outdoor switchyard. To ensure the long-term stability and safety of the facility, crews are reinforcing the banks of the upper and lower reaches of the Ortho-Tokoy reservoir and installing safety systems required for future operations.
