The construction of the Rogun HPP will provide sufficient electricity to eliminate winter shortages

Currently, rural residents of the country receive limited amounts of light.

The construction of the Rogun HPP will provide sufficient electricity to eliminate winter shortages, according to the Updated Environmental and Social Impact Assessment of the Rogun HPP Project.

The consultation document notes that currently energy supply in Tajikistan is seasonal: there is a surplus in the summer and a deficit in the winter.

“Residents of rural and remote areas (70% of the population) suffer the most from this,” emphasize the authors of the document, which is published on the website of Rogun HPP OJSC.

The Updated Assessment notes that construction of the Rogun Reservoir will be fully completed in 2029: it will fill more and more every year within the limits of water distribution between the countries of the region, and will reach its maximum level in 2036.

  Note that the plant will be able to operate at full capacity only after filling the reservoir to the maximum level.

The document emphasizes that the total installed capacity of the Rogun HPP will be 3,600 MW.

It is expected that after the plant is fully commissioned, its annual electricity generation will be approximately 17 billion kWh.

The Rogun HPP project includes a 335 m high dam with a reservoir approximately 80 km long and 4 km wide, as well as associated hydro turbines, power lines and infrastructure.

  The expected lifespan of this plant is 115 years.

Brief history of the project

The Rogun hydroelectric power plant project was developed in the 1960s.

The final decision on construction was made in 1980, and main construction work began in 1982.

  In 1993, as a result of flooding, the construction diversion tunnels became clogged with sediment and the cofferdam was destroyed.

  In May 2008, the government of Tajikistan announced the resumption of construction of the plant.

Limited construction and operational work continued until 2011, after which feasibility studies (FS) began and were completed in 2014.

The feasibility study confirmed the feasibility of the design, construction and operation of the hydroelectric power plant.

The launch of the first of 6 Rogun hydraulic units at low capacity took place in 2018, the second in 2019.

The last unit is expected to be commissioned in 2029.
