Study of the Composition and Operation Parameters of Hydroelectric Power Plants in the Tajikistan Power System

The article presents the parameters of the functioning of the national power system and hydroelectric power plants (HPP) of Tajikistan. As of 01.01.2020, Tajikistan power plants with an installed capacity of 6451 MW generated 21 bln kWh of electricity. At the same time, 19.5 bln kWh (92%) were generated by HPPs with a total installed capacity of 5202 MW. The study for 13 Tajikistan HPPs operating in the Pamir and Tien Shan mountains lists the names, commissioning date, altitude, installed capacity and other parameters. The country is implementing a program for the development of hydropower resources with an increase in HPP capacity by 2039 to ~29000 MW. The Tajikistan experience of construction and operation of HPP is unique for studying both in terms of working in HPPs in mountainous conditions, and in terms of 100% supply of the country's for cheap electricity.
