The construction of Kambaratinskaya HPP-1, with a capacity of 1860 megawatts, is entering an active phase. This strategically important project for Central Asia has demonstrated significant achievements in both engineering aspects and attracting investments, as was announced at the Ministry of Energy's board meeting in 2025.
Investments and Expertise
Last year, a competition was held to update the feasibility study (FS) developed in 2014. Currently, experts have determined the type of dam that will be constructed.
The World Bank, which supports this project, has added an additional $13.6 million to the previously allocated $5 million. Furthermore, the possibility of allocating $1.5 billion for the main construction works is being considered.
Nine international donors have also expressed their readiness to invest approximately $2.5 billion in the project.
The development of the environmental and social impact assessment (ESIA), for which the World Bank allocated $18.6 million, has been completed.
International Cooperation
On September 30, 2025, the draft intergovernmental agreement was sent to the ministries of energy of Kazakhstan and Uzbekistan, where the parties discussed their proposals and comments. An interdepartmental working group from the Kyrgyz Republic is preparing for final negotiations with experts.
Progress of Construction Works
A significant amount of preparatory work was completed at the HPP construction site last year:
1. The construction of an 8.6-kilometer concrete road from the Bishkek — Osh highway to notch No. 2 has been completed. On the next section, 4 kilometers out of the planned 4.7 have been laid (readiness — 85 percent).
2. Drilling and concrete works in the transport tunnel TT-2 (126 meters) have been completed, and the facility is undergoing acceptance. Four concrete bridge supports over 180 meters long have been built on the right bank of the Naryn River (overall readiness — 50-60 percent).
3. The overhead power line of 110 kilovolts, stretching 11.5 kilometers, has been fully installed, with 25 supports erected.
4. The shift camp for 100 people, including an administrative building, dormitory, and cafeteria, is 60-70 percent ready.
5. The concrete road for the operational phase in tunnel TT-2 (1 kilometer 387 meters) is fully ready, and internal structural works are ongoing (overall readiness — 55-60 percent).
