According to information provided by the ministry, the upgrade of hydro unit No. 3 has been completed as part of the third phase of the Toktogul HPP rehabilitation project. This upgrade resulted in an increase of its capacity by 60 MW. All four hydro units of the Toktogul HPP have undergone modernization, which allowed for an increase in the total installed capacity of the station from 1200 MW by an additional 240 MW, reaching a final value of 1440 MW.
In 2025, work was also carried out to modernize the second hydro unit of the Uch-Kurgan HPP, which allowed for an increase in its capacity by 9 MW. It is specified that the modernization of the first hydro unit was already completed in 2024. As a result, the total capacity of the Uch-Kurgan HPP increased by 18 MW, rising from the initial 180 MW. Plans for 2026 include the modernization of the remaining two hydro units.
Thus, as a result of the reconstruction of hydro units at major HPPs in 2025, the total installed capacity of the energy system was increased by 69 MW.
