STAGES OF DEVELOPMENT OF JSC «HYDROPROJECT»
By the end of a decade almost all HPP were built on the flat river regions such as Chirchik-Bozsu tract in Uzbekistan, Varzob river in Tadjikistan, Chuy main channel in Kyrgyzstan, Murgab river in Turkmenistan.
A transition was made from construction of minor and medium capacity HPPs to the creation of large riverbed HPPs: Kairakum (1951-1957) and Shardara, construction of the most powerful in Central Asia at that time two riverbed HPPs: Golovnaya on the river Vakhsh with the capacity of 210 MW and Uchkurgan on the river Naryn of 180 MW.
Altogether, during this period 16 HPPs were built with the total capacity of 366 MW.
Hydropower construction in Central Asia reaches top level claimed by the international experience. Design was coming to an end and construction of three unique reservoir water complexes began: Nurek on the river Vakhsh with the highest earth dam in the world of 300 m high and HPP with the capacity of 2700 MW, Toktogul on the river Naryn with the concrete dam 215 m high and HPP with the capacity of 1200 MW, Charvak on the river Chirchik with the earth dam 168 m high and HPP with the capacity of 600 MW.
Three large riverbed HPPs were completed and put into operation: Kairakum, Shardara and Uchkurgan.
Overall, 4 HPPs were launched with the total capacity of 658 MW.
Power units were launched on the three unique HPPs of Central Asia: Nurek, Toktogul and Charvak, while the first HPP units were put into operation with reduced heads and unfinished dams. In 1977 Charvak water complex was put into permanent commission.
A construction of the largest Tuyamuyun water complex in Uzbekistan on the river Amudarya with HPP of 150 MW was in progress and the construction of Khodjikent and Gazalkent HPPs with the capacities of 165 and 120 MW correspondingly was coming to an end.
In 1976 a construction of Kurpsay HPP on the river Naryn with the capacity of 800 MW started in the Republic of Kyrgyzstan, by that time Papan water reservoir complex on the Akbura river with the dam 120 m high.
All in all. 4 HPPs with the total capacity of 4550 MW were built during the decade.
The schemes of water resource development updated dynamically and medium- and long-term perspectives of HPP construction outlined.
By the end of 1990s the capacity of all the HPPs in the consolidated energy system of Central Asia constituted 34% of the total installed capacity and 24% of the total energy output, which indicated the signigicant share of HPPs in the energy system.
