Kazakhstan, Kyrgyzstan, and Uzbekistan have signed a trilateral protocol on water and energy cooperation, covering the upcoming winter heating period and the 2026 agricultural season. The agreement was formalized at a meeting of the countries’ energy and water ministers held in Almaty on November 22.

With water levels at Kyrgyzstan’s Toktogul Hydropower Plant (HPP) reservoir critically low, Kazakhstan and Uzbekistan have agreed to supply electricity to Kyrgyzstan during the winter months. This will allow Kyrgyzstan to reduce electricity generation during peak heating demand and conserve water in the Toktogul Reservoir. The stored water will later be released downstream to Kazakhstan and Uzbekistan during the 2026 growing season to ensure consistent irrigation for farmland in their southern regions.

The Toktogul HPP, located on the Naryn River, a key tributary of the Syr Darya, is Kyrgyzstan’s largest power station, supplying about 40% of the country’s electricity. It plays a dual role: meeting domestic energy needs and regulating water flows critical to downstream agricultural systems. In winter, Kyrgyzstan typically ramps up power output to meet heating demand, often at the expense of reservoir levels, which can compromise irrigation capacity the following spring.

Under the new protocol, Uzbekistan has also pledged to support regional electricity balancing and ensure transit capacity.

Earlier, the three countries agreed to facilitate cross-border electricity flows, including Russian electricity transiting to Kyrgyzstan via Kazakhstan, and Turkmen electricity reaching Kyrgyzstan through Uzbekistan’s transmission grid.

Participants in the Almaty meeting emphasized that the trilateral agreement reflects a spirit of good neighborliness and is aimed at enhancing regional energy security and stability.

The agreement is particularly critical for Kyrgyzstan, which faces persistent electricity shortages, especially during the winter when electric heating is widely used.

On November 18, Kyrgyzstan completed the full modernization of the Toktogul HPP, with the commissioning of its fourth generating unit. The upgrade raised the facility’s total capacity from 1,200 MW to 1,440 MW.

In parallel, Kyrgyzstan is advancing construction of the Kambarata-1 HPP, a major regional project being developed jointly with Kazakhstan and Uzbekistan. Once completed, Kambarata-1 will have a generation capacity of 1,860 MW and produce 5.6 billion kWh annually.
