Narun
A tributary of the Syr River on the right bank
The Naren River is a tributary of the Syr River on the right bank. Originating from the Central Tianshan Glacier and flowing through Kyrgyzstan and Uzbekistan, the river originates from meltwater of glaciers and snow in the central Tianshan Mountains, and is called the Syr River after joining the Kara River in the eastern Fergana Basin. Fed by snow and glaciers, it flows 700 kilometers to the west, with many tributaries and a drainage area of 58,370 square kilometers. The downstream is rich in irrigation. Fergana Canal from this river, built the Toktogul hydropower station and so on.

Toktogul
(Toktogul),
Ukhkurgan
(Uchkurgan) two reservoirs, with flood control, power generation, irrigation and other benefits.
The Fergana Canal
Water is diverted from this river. On the Naren River, there are three large and medium-sized cascade hydropower stations, including the Toktogul Hydropower Station.
The Narun River, which is the largest tributary of Asia's famous river Syr, originates from
Akshrak Mountain
The glacier is more than 800 kilometers long and 535 kilometers long in Kyrgyzstan. The catchment area of the Nalun River covers 53,700 square kilometers, accounting for 27% of the national territory, with an average flow of 90 cubic meters per second upstream and 429 cubic meters per second downstream. With a water level drop of up to 3,000 meters from the source to the mouth of the Narun River, it has a huge power generation potential, and the hydropower generation of the Narun River alone accounts for 95% of the electricity generated in Kyrgyzstan.
The Narun River can generate electricity as well as water for irrigation, such as the Tortogu hydropower Station, which holds up to 20 billion cubic meters of water in its reservoir and can irrigate 400,000 hectares of barren land.
Narun
Toktogul hydropower Station
Located on the Narun River in the Kyrgyz Republic, the dam is 215 meters high. Four hydropower stations are installed, with a single capacity of 300,000 kilowatts, a total installed capacity of 1.2 million kilowatts, and an average annual power generation of 4.4 billion KWH. The total storage capacity of the reservoir is 19.5 billion cubic meters, and the effective storage capacity is 14 billion cubic meters. The project has comprehensive benefits such as power generation, irrigation and shipping. Construction began in 1965, the first unit was put into operation in 1973, and all were completed in 1978.
Kambalakin hydropower Station
The design power is 2.2 million kilowatts, and the annual production capacity is expected to exceed 6 billion kilowatt-hours after completion, with a total investment of about 1.9 to 2 billion US dollars. The hydropower station has been under construction since 1990, but has not yet been completed due to lack of funds from the Kyrgyz government.
Kyrgyzstan
The first hydropower station was built in 1929
Little Aramenkin hydroelectric power Station
The power generation capacity is only 410 kW. In 1942, the Swan Hydropower Station, the largest at the time, was built with a power generation capacity of 4,200 kilowatts. Six canal hydropower stations were built between 1945 and 1958, with a total generating capacity of 21,780 kW. In the 1950s, the Institute of Hydraulic Economics and hydraulic Power of the Kyrgyz Academy of Sciences, after a lot of investigation and research, decided to make full use of the hydropower resources of the Nalun River to generate electricity, and planned to build 22 cascade hydropower stations in the Nalun River, with a total power generation capacity of about 7 million kilowatts. By 1982, the four Nalun River cascade hydropower stations had been built successively, with a total power generation capacity of 2.22 million kilowatts. Not only does it supply the country, but a third goes abroad.
