Modernization of Kyrgyzstan’s Largest Hydropower Plant Nears Finish

Kyrgyzstan is approaching a significant milestone in its energy sector with the upcoming completion of modernization work at the Toktogul Hydropower Plant (HPP), the country's largest energy facility, which generates around 40% of its electricity.

According to the Ministry of Energy, the country consumed 10 billion kilowatt-hours (kWh) of electricity in the first half of 2025, of which 2.05 billion kWh were imported, The Caspian Post reports citing foreign media.

Domestic production during this period included 6.616 billion kWh from large hydroelectric plants, 1.132 billion kWh from thermal power plants, 219.7 million kWh from small HPPs, and 0.141 million kWh from the nation’s only solar power plant.

To reduce dependence on imports and address recurring power shortages, the government is prioritizing both the construction of new and the modernization of existing hydropower facilities.

On July 15, a major milestone was reached at Toktogul HPP with the installation of a new rotor for hydroelectric unit No. 3, the last of the plant’s four turbines to undergo a full overhaul under a multi-year modernization project. The rotor, weighing 768 tons, is the heaviest component of the unit and was installed using two 400-ton cranes. A similar operation was last carried out nearly five decades ago, during the plant’s initial construction.

Three of the four turbines have already been upgraded. Upon completion of work on unit No. 3 in November 2025, Toktogul’s total installed capacity will rise by 240 megawatts (MW), reaching 1,440 MW. This upgrade will enable the plant to generate an additional 525.3 million kWh of electricity annually.

Alongside the Toktogul modernization, Kyrgyzstan is also advancing its small-scale hydropower capacity. By the end of 2025, 18 small hydropower plants with a combined capacity of 78.57 MW are expected to be completed. Two plants, with a total capacity of 10.29 MW, are already in test operation.

Although the country’s only solar power plant currently produces 1.43 MW, this is set to change. Kyrgyzstan has launched construction of two major renewable energy projects in 2025: a 300 MW solar power plant and a 100 MW wind farm, marking a significant step toward diversifying the national energy mix and enhancing long-term energy security.
