At the Toktogul hydroelectric power station in Kyrgyzstan, one of the key and most technically complex stages of large-scale modernization has been completed — installation of a rotor in the generator shaft of the fourth and last hydraulic unit № 3. This unique operation marks the end of the project to renovate the country’s largest power plant, reports the Republic’s Ministry of Energy.
The heart of the hydraulic unit, a rotor weighing 768 tons, was installed in its place with pinpoint precision using two overhead cranes, each of which is capable of lifting up to 400 tons. A task of similar complexity and scale was carried out at the station only once — half a century ago, during its construction. Today’s event, carried out using modern technologies, opens a new page in the history of Kyrgyz energy.
Work on the reconstruction of the final hydraulic unit is in full swing and is at the final stage. At the moment, the rotor assembly is completely completed, the stator is 95 percent ready, and the turbine installation is 72.3 percent complete. The overall progress in replacing the entire hydraulic unit is more than 70 percent, which confirms the high pace of project implementation.
The full completion of reconstruction, scheduled for November 2025, will bring Kyrgyzstan a significant increase in energy security. The modernization of four hydraulic units will increase the installed capacity of the Toktogul hydroelectric power station by 240 megawatts, bringing it to 1,440 megawatts.
