On November 19, Kyrgyzstan inaugurated the modernized hydroelectric generating unit No. 1 at the Toktogul Hydroelectric Power Plant (HPP), the nation's largest energy facility. Situated on the Naryn River, the Toktogul HPP produces around 40% of Kyrgyzstan's electricity, The Caspian Post reports citing foreign media.

The modernization of hydroelectric unit No. 1 began in March 2024 and has increased its generating capacity by 60 MW. Prior to this upgrade, the Toktogul HPP had a total capacity of 1,200 MW, with each of its four units producing 300 MW. Two units had already been upgraded in previous phases, collectively adding 120 MW to the plant’s total capacity.

The reconstruction of the fourth and final hydroelectric unit is scheduled for 2025. Once the modernization project is complete, Toktogul HPP will gain an additional 240 MW of generating capacity, extending its service life by 25–30 years.

The $210 million rehabilitation project is funded by a $110 million loan from the Asian Development Bank (ADB) and $100 million from the Eurasian Fund for Stabilization and Development (EFSD).

With a total volume of 19.5 billion cubic meters, the Toktogul HPP reservoir plays a dual role in meeting Kyrgyzstan’s energy demands and providing essential irrigation water to Kazakhstan and Uzbekistan. During the winter, increased water releases are used to generate electricity for Kyrgyzstan, while summer releases support irrigation for southern Kazakhstan’s dry regions.

As of November 19, 2024, the Toktogul reservoir contained 12.991 billion cubic meters of water, compared to 11.694 billion cubic meters on the same date in 2023. The reservoir currently receives 246 cubic meters of water per second and releases 488 cubic meters per second.

Despite this year’s higher water levels, Kyrgyzstan continues to face electricity shortages, according to Energy Minister Taalaibek Ibrayev. Toktogul HPP’s modernization and efficient management of water resources remain critical to addressing these challenges and ensuring regional energy and water security.
