Chelyabinsk state district power station: history, modernization

Chelyabinsk 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 capacity of 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 Chelyabinsk and the region began their rapid development.

History

Chelyabinsk GRES was the last, the twenty-seventh station, which was built according to the plan of GOELRO. 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 Shaturskaya GRES was also involved. The construction was started in 1927, the planned design capacity is 150 MW. The station was laid on the first decade of the October Revolution, namely on November 6, 1927.

The first generator produced industrial power in 1930, on September 15, two years later the Chelyabinsk GRES gave out a capacity of 100 MW, the design mark was reached in 1935. The received electric power was planned to be directed to industrial facilities located in Kyshtym, Karabash, Zlatoust.

Development of Chelyabinsk and the region

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

Chelyabinsk GRES opened the era of construction of enterprises of industrial importance. In a short time, several large complexes were launched - a tractor plant, a metallurgical plant, a ferroalloy plant, a paint and varnish plant, a polishing factory, zinc and other enterprises of the city and the region.

The work of the station solved an important problem - effective utilization of low-grade Ural coal. In 1930, several power plants, including Chelyabinskaya GRES, were merged into a single system - Uralenergo. The station was connected to the Sverdlovsk line in 1931 via the Kyshtym-Ufaley electrical substation. After five years of operation, the power was 121 MW, by 1936 the design targets were 150 MW.

Stable work

During the war of 1941-1945, the Chelyabinsk GRES uninterruptedly supplied electricity to the defense enterprises of the city and the region. For successful fulfillment of the tasks, the ChGRES was awarded the Order of Lenin.

At the turn of the 50-60s, the Chelyabinsk power plant - one of the first in the Urals - was rebuilt. As a result of the modernization, there was an opportunity to generate heat and electricity. The last modernization of this period concerned the transfer of the power plant from coal to gas, and since 1963 natural gas has been used as fuel for uninterrupted operation.

The Turning Nineties

In 1993, the Chelyabenergo company changed its legal status and became a joint stock company - OJSC Chelyabenergo. Several years later, in 2005, within the framework of the national plan for reforming the energy sector, the Chelyabenergo Open Joint-Stock Company was assigned the structure of Chelyabinskaya Generating company ", part of which was Chelyabinsk GRES. In the course of further reforms, Fortum OJSC was formed, which combined the Chelyabinsk Generation Company and the Tyumen Regional Generation Company.

Modernization

In 2007, the ChGRES replaced the obsolete power equipment that had been in operation since 1931. The old turbine of Metropolitan Vickers was replaced with domestic assembly 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 power of 150 Gcal / h. The second launch of CHGES took place on October 18, 2016.

After the work, the station retained the possibility of generating thermal and electric energy. The thermal power is 700 Gcal / h, the electric power is 494 MW. The design efficiency of the combined-cycle plant is 52%, which is significantly higher than the standard values (about 35%).

GRES in Troitsk

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

The first took place in the period of 2008-2012, during the works cleaning equipment was replaced. In 2013-2014, power units No. 8 and 9 were replaced, and a new power unit No. 10 was built. To date, the electric capacity of Troitskaya GRES is 1,400 MW, and the heat output is 515 Gcal / h. The total number of the station personnel is 1154 people. The fuel used is coal, the kindling is carried out using fuel oil. The station is a city-forming enterprise, around which there is a village of GRES (Chelyabinsk region).

Settlement of GRES

The village of GRES (Troitsk, Chelyabinsk region) was built in 1954. It was at this time that the first work on the construction of a hydroelectric power station took place. In 2014, the 60th anniversary of the settlement was solemnly celebrated. The bulk of its residents work at Troitskaya GRES, near which it arose. Today, about 11 thousand people live here. The general condition of the housing stock and communications is thoroughly worn out, but in the coming years no one plans to carry out repair and capital repairs on the infrastructure site. Currently, the administration of Troitskaya GRES is trying to transfer the settlement to the balance of the city of Troitsk.
