Bishkek, Sept. 22, 2025. /Kabar/. On September 22, a key and technically complex stage of the modernization of the Uch-Kurgan Hydroelectric Power Plant (HPP) was successfully completed: the installation of a rotor in the shaft of Hydroelectric Generator No. 3, Ministry of Energy reported.
According to the ministry, this is the second of four units to be reconstructed as part of the large-scale plant renovation project. The rotor, weighing 221.2 tons, is the heaviest and largest component of the unit. It was installed using a 250-ton overhead crane. A similar operation has only been performed once before at the Uch-Kurgan HPP, approximately 60 years ago, during Soviet times, when the plant itself was being built. This time, the historic event was repeated, but with the use of modern technologies and equipment.
Up to date, approximately 70% of the reconstruction work on the second hydroelectric unit (HPU No. 3) has been completed. The remaining installation work is being carried out at an accelerated pace. The general contractor for the project is CNEEC (China National Electric Engineering Co. Ltd.).
The current progress of work on the second hydroelectric unit is as follows:
* Dismantling – 100%
* Installation – 70%
* Stator Assembly – 100%
* Rotor Assembly – 100%
* Additional Work – 100%
* SCADA System Installation – 27.4%
* Dewatering Systems – 49.8%
* Lubrication and Technical Systems – 41.2%
* Lifting mechanism – 24.7%
* Main low voltage gas substation – 12.9%
* 110 kV open switchgear – 3.4%
The current installed capacity of the Uch-Kurgan Hydroelectric Power Plant is 189 MW. Following the completion of the reconstruction of the second hydroelectric unit, the station's capacity will increase by 9 MW, significantly improving the reliability and stability of the region's power supply. Completion of the work and commissioning of the unit are scheduled for November 2025.
