Chelyabinskaya GRES was built in the era of electrification of the country and became the last in the chain of stations of the GOELRO plan. After its launch, the power plant was planned to be used for heating the city and the operation of several small enterprises. But thanks to the available energy that appeared, Chelyabinsk and the region began their rapid development.

History

Chelyabinskaya GRES was the last, twenty-seventh station, which was built according to the GOELRO plan. The project was developed in 1923, it provided for the construction of a station with two turbines, each of which had a capacity of 5000 kW, and the equipment of the Shaturskaya GRES was also involved. The construction was started in 1927, the planned design capacity is 150 MW. The laying of the station took place on the first tenth anniversary of the October Revolution, namely on November 6, 1927.

The first generator produced industrial current in 1930, on September 15, two years later the Chelyabinsk State District Power Plant produced a capacity of 100 MW, the design mark was reached in 1935. The resulting electricity was planned to be sent to industrial facilities located in Kyshtym, Karabash, Zlatoust.

Development of Chelyabinsk and the region

GRES in the Chelyabinsk region after the launch served as an impetus for the development of the region's industry. It was the first powerful power plant in the South Urals. The first plans for the development of the region included the construction of a plant for the production of sand-lime bricks and a weaving factory. These modest plans for the use of the received capacities were revised in connection with the idea of industrializing the country.

Chelyabinsk State District Power Plant opened the era of construction of industrial enterprises. In a short time, several large complexes were launched - a tractor plant, a metallurgical plant, a ferroalloy plant, a paint and varnish plant, a grinding plant, zinc and other enterprises of the city and the region.

The operation of the station solved an important problem - the efficient utilization of low-grade Ural coal. In 1930, several power plants, including the Chelyabinsk State District Power Plant, were merged into a single system - Uralenergo. The station was connected to the Sverdlovsk line in 1931 through the Kyshtym-Ufaley electrical substation. After five years of operation of the station, the capacity was 121 MW, by 1936 the design indicators were reached - 150 MW.

Stable operation

During the war of 1941-1945, the Chelyabinsk State District Power Plant uninterruptedly supplied electricity to the defense enterprises of the city and the region. For successfulfulfilling the tasks of ChGRES was awarded the Order of Lenin.

At the turn of the 1950s and 1960s, the Chelyabinsk power plant, one of the first in the Urals, was reconstructed. As a result of the modernization, it became possible to generate heat and electricity. The last upgrade of this period concerned the conversion of the power plant from coal to gas, and since 1963 natural gas has been used as fuel for smooth operation.

The turning point of the 90s

In 1993, the Chelyabenergo enterprise changed its legal status and became a joint-stock company - Chelyabenergo OJSC. A few years later, in 2005, as part of the national energy reform plan, Chelyabenergo was the structure of OAO Chelyabinsk Generating Company was separated, of which Chelyabinsk State District Power Plant became a part. In the course of further reformation, Fortum OJSC was formed, merging Chelyabinsk Generating Company and Tyumen Regional Generating Company.

Modernization

In 2007, ChGRES replaced outdated power equipment that had been in operation since 1931. The old turbine of the Metropolitan-Vickers company was replaced with domestically assembled equipment manufactured at the Kaluga Turbine Plant. The next stage of modernization began in 2012 with the construction of two new power units, each with an electric capacity of 247.5 MW and a thermal capacity of 150 Gcal/h. The second launch of ChGRES took place on October 18, 2016.

After theworks, the station retained the ability to generate heat and electricity. Thermal power is 700 Gcal/hour, electrical power is 494 MW. The design efficiency of the CCGT plant is 52%, which is significantly higher than the standard indicators (about 35%).

GRES in Troitsk

Troitskaya GRES (Chelyabinsk region) is located in the city from which it got its name. The station was built in 1960, today it is part of the OGK-2 enterprise. During the period of operation, two waves of modernization were carried out.

The first one took place in the period 2008-2012, during the work the treatment equipment was replaced. In 2013-2014, power units No. 8 and 9 were replaced, a new power unit No. 10 was built. To date, the electrical capacity of the Troitskaya GRES is 1,400 MW, and the thermal capacity is 515 Gcal/h. The total number of station personnel is 1154 people. Coal is used as fuel, kindling is carried out using fuel oil. The station is a city-forming enterprise, around which the GRES settlement (Chelyabinsk region) is located.

GRES settlement

GRES settlement (Troitsk, Chelyabinsk region) was built in 1954. It was to this time that the first work on the construction of a hydroelectric power station dates back. In 2014, the 60th anniversary of the settlement was solemnly celebrated. The main part of its inhabitants works at the Troitskaya State District Power Plant, near which it arose. Today, about 11 thousand people live here. GeneralThe condition of the housing stock and communications is thoroughly worn out, but in the coming years no one plans to carry out restoration and major repairs at the infrastructure facility. At present, the administration of the Troitskaya GRES is trying to transfer the settlement to the balance of the city of Troitsk.
