General Information
The construction of the hydroelectric power station began in 1963, and ended in 1980 . The hydropower plant was commissioned in 1979 .
The composition of hydroelectric power plants [1] :
- a concrete gravity dam with a length of 1475 m and a height of 105 m, consisting of a station dam 396 m long, a spillway dam 242 m long, and dull parts of the dam (in the channel and banks) 837 m long.
- left-bank stone-earthen dam 1710 m long and 28 m high.
- right-bank earthen (sand) dam 538 m long and 47 m high.
- 440 m long dam building
The height of the upper pool above sea level (NPU) is 296 m. [2] A road passage has been laid along the dam of the hydroelectric station, along which traffic is closed. The hydroelectric station does not have access gates; in the future, the construction of a ship-lift is envisaged.
The installed capacity of hydroelectric power stations is 3840 MW [3] , the average annual generation is 21.7 billion kW⋅h . The hydroelectric station building has 16 radial-axial hydraulic units with a capacity of 240 MW each, operating at a working head of 90.7 m. The pressure structures of the hydroelectric station (pressure front length 3.84 km) form the large Ust-Ilim reservoir of long-term regulation with an area of 1922 km², a total volume of 58 , 9 km³. When the reservoir was created, 154.9 thousand hectares of land were flooded, including 31.8 thousand hectares of farmland. 14.2 thousand people from 61 settlements were resettled. 11.9 million m³ of forest were cut down.
The power plant was designed by the Hydroproject Institute . The project of the station included the construction of a hydroelectric power station with a capacity of 4320 MW with 18 units. In fact, the station was built with 16 units, a backlog was created for units No. 17 and 18 (turbine water conduits and suction pipes with valves were mounted) [4] .
As of the end of 2012, there are still restrictions on the power output of the Ust-Ilim HPP (up to 590 MW) [3] .
The Ust-Ilim HPP is controlled by Irkutskenergo , but the hydroelectric dam is owned by RusHydro.
The Ust-Ilim HPP is the fourth largest in Russia, second only to the Sayano-Shushenskaya, Krasnoyarsk and Bratsk hydroelectric plants.
Economic Significance
The Ust-Ilim HPP plays an important role in ensuring the stability of the Siberian energy system. A significant part of the hydroelectric power is consumed by aluminum and wood-chemical plants. The hydropower station has become the basis for the creation of the Ust-Ilimsk territorial-production complex.
In 2012, hydropower generation amounted to 32.3% of the total generation of power plants in the Irkutsk region [3] .
History of construction and operation
In 1959, the Moscow State Institute of Designing Power Plants and Substations founded in with. Nevon Angarsk complex survey party to study the thermal regime of the Angara, the direction of future high-voltage transmission lines. In September 1960, the State Commission decided: to recognize as the most appropriate place for the construction of the Ust-Ilim hydroelectric complex, a target 20 km below the mouth of the river. Ilim , on the Angara, at the rocky Cape of Tolstoy.
The decree of the Central Committee of the CPSU and the Council of Ministers of the USSR of June 8, 1962 determined the start of construction and installed capacity. On August 22, 1962, an order was issued to begin preparatory work for the construction of the Ust-Ilim HPP.
In accordance with the project, the construction of the Ust-Ilim hydroelectric station was divided into two stages. The first - the implementation of preparatory work - amounted to five years: from 1963 to 1967 . During this time, the construction site on the left bank of the Angara was mastered, utility production enterprises: concrete, reinforcing plants, auto repair shops, hydro-construction village, the power transmission line Bratsk - Ust-Ilimsk was laid. In June 1966 , a permanent through passage was opened on the highway from Bratsk to the future Ust-Ilim Hydroelectric Power Station. In March 1966 , work began on the main structures of the waterworks. This date is considered the official start of the construction of the hydroelectric station. In February 1967 , the first closure of the Angara was made. Since 1968, builders began the construction of the main facilities of a hydroelectric power station. The second phase of construction began, lasting seven years: from 1968 to 1974 .
On April 22, 1968 , the first cubic meter of concrete was laid in the dam of the hydroelectric power station. The second overlap of the Angara river bed was carried out on August 13, 1969 . On October 3, 1974 , the filling of the Ust-Ilim reservoir began; it lasted until 1977 . The first unit of the hydroelectric power station gave an industrial current on December 28, 1974 , and on May 20, 1975, the hydroelectric power station generated its first billion kWh of electricity. In 1975 - 1977 , 4 units were introduced annually. On October 25, 1977, with the launch of the 15th unit, the Ust-Ilim Hydroelectric Power Station was launched at full capacity of the first stage - 3600 MW. In October 1978, the hydroelectric power station generated 50 billion kWh of electricity. At the end of March 1979 , the last - the sixteenth station unit - was included in the network. In December 1980, the hydroelectric power station was put into commercial operation.
In 2010, the generation of 700 billion kWh was recorded [1] .
