Donbasenergo PJSC

History

History of Donbasenergo

is the story of one of the first and most powerful energy systems of the XX century.

It is a record of events that took decisive importance for the huge country's economy and energy development far beyond its borders. This is the story of how industrial giants grew in the Donetsk steppe – but, more important, advanced scientific ideas were successfully implementing here and trailblazing

industrial experiments were conducted, shaping trends in the industry's development worldwide. This is a story of innovation, which has no economic life, but has the ability to be repeated in each of the next generation of power engineers.

1930y.

1940y.

The association of state power station of the Donetsk coal basin Donbasstok was organized (later - District Office Donenergo) for production, distribution and marketing of electricity. It included the first two GRES power plants built in the region, according to the GOELRO electrification plan, Shterivska and Severodonetsk. Also, the association exploited first in Ukraine transmission line voltage 110 kilowatt Shterivska GRES - Kadiyevka.
The first in the country and the largest in Europe 100 MW turbogenerator commissioned at Zuevskaya TPP - the station became one of the most powerful generating enterprises of the USSR, producing 54% of Donenergo electricity.
The first in Ukraine station 220 kilovolt power line with the length of 87 km was built in the direction of Zuevka - Kurakhovka

1941y.

1951y.

First unit of the Kurakhovo GRES was put into operation. Zuivska GRES, after reaching a capacity of 350 MW, became then the largest power plant in Europe.
Donenergo renamed into regional energy management Donbasenergo (regional electricity board Donbasenergo), which became the largest in Ukraine after the war: 14 companies, including 4 GRES, which then employed more than 9 thousand people.
Construction of the Mironovskaya GRES - the first a typical power plant in the USSR, equipped with 100-strong high-pressure turbines with hydrogen cooling.
Construction of the Slaviansk GRES, the first phase of which (non-block part) has been fully operational in 1957.

1952y.

1966y.

Starobeshevo GRES - the first thermal station in the USSR and the most powerful in Europe at the time of commissioning - is built by high-speed industrial method with combination of construction and the extensive use of precast concrete. In 1958, turbine generator No. 1 was connected to the network, in 1959 - second and third units were commissioned.
Mironivskii GRES becomes the most powerful and cost-effective in the Donbass power system: actual indicators of specific fuel consumption and electricity consumption for own needs were lower than design.
In the early 1960's, equipment models, new for Europe, put into production at the Slaviansk GRES - 800 MW blocks.
In 1966, Donbasenergo’s total installed capacity has reached 5,925 MW: Donbass produced electricity 20 times more than the whole tsarist Russia.

1967y.

1974y.

The first Soviet twin-shaft unit of 800 MW (unit No. 6) was put into operation at the Slaviansk GRES. In 1971, another 8-hundred unit (No. 7) was connected to the network.
The installation, first in the country, of power units of 200 MW started at the Starobeshevo GRES, which were a new phenomenon in the Soviet power: boiler, turbine and generator were combined here into a single system, controlled from a single switch desk. The blocks were assembled from the major elements which helped to accelerate the construction: half of Dniproges grew in 365 days. In 1967-68, Starobeshevo GRES developed a power greater than any other power station in the world.
Construction of Uglegorsk TPP started, which then became the largest thermal power plant of the Soviet Union and Europe. In 1977, its capacity was increased to 3.6 million kWh, which is 2.5 times more than GOELRO. Donbasenergo achieved the first place among the power systems of the USSR.

1975y.

1979y.

Power station ZuGRES-2 is built, which has become the youngest in Ukraine.
Mill charge at the GRES is fully automated, combustion processes – up to 97.6%, existing fuel supply systems – up to 56.2%. 92.7% of boiler plants are equipped with central alarm technology and thermal protection for the extended service area.
The regional electricity board transformed into industrial power group - PEO Donbasenergo: 10 thermal power plants, 13 enterprises of electric networks, 9 repair and auxiliary enterprises, which employ more than 37 thousand people.
750 kV transmission line Donbass-Zapadnoukrainskaya-Albertirsa (Hungary) united energy systems of Ukraine, Bulgaria, Hungary, Poland, Romania and Czechoslovakia.
In 1978, Donbasenergo’s system produced 1 trillion kWh - as much as a total of all the power stations of the Soviet Union at the time.

1980y.

1990y.

Automated system of dispatch control system was introduced at Donbasenergo: operation of all power stations of the group and industrial plants controlled from a single center. Capacity of the Donbasenergo power stations was close to 13 million kW - this would be enough to cover the electricity needs of two countries such as Hungary and Yugoslavia.
Teams of Donetsk, Sergovski, Krasnodon and Krasnoluchsk enterprises of electric networks crossed over to team pool payment system as a progressive form of labor organization, as did some shifts at the Uglegorsk, Slaviansk, Kurakhovo and Voroshilovgrad power stations.
Donbasenergo is the most powerful energy system in the USSR: 34 enterprises, employing 43 thousand people, serving over 80 settlements of Donetsk and Voroshilovgrad (Luhansk) region with a population of 9 million people.

1991y.

2010y.

Status of the state district power plant (GRES) changed to thermal power plants (TPP).
First stage of Donbasenergo reorganization: generation, supply and distribution systems, supervisory control networks were separated. State power generation enterprise Donbasenergo was formed on the basis of the five thermal power plants - Kurakhovo, Zuevskaya, Starobeshevo, Slaviansk and Luhansk with total installed capacity of 7610 MW generating company established (later - state joint stock company, and then - OJSC Donbasenergo).
The Verkhovna Rada adopted the National Energy Program until 2010, which mentions the possibility of reconstruction of the Slaviansk TPP.
Following the results of the second phase of the reorganization, Zuyevskaya, Kurakhovo and Luhansk TPPs became part of the generation of Vostokenergo. Starobeshevo and Slaviansk TPP with total capacity of 3550 MW remained on the books of Donbasenergo.

2011y.

2022y.

At the Starobeshevo TPP, on the basis of the modernized unit No. 4, the first the former Soviet Union, boiler with combustion technology in circulating fluidized bed (CFB) was put into operation. Boiler’s efficiency at full power is 90.5%, trapping efficiency - 99.97%.
The launch of Comprehensive investment program of the Donbasenergo PJSC, which is provided until 2025. The reconstruction of power units No. 13 and 12 of the Starobeshevo TPP were performed with the construction of modern electrostatic precipitators – the installed capacity increased by 20 MW. Stages I and II of the reconstruction unit No. 7 of the Slaviansk TPP were completed, maneuvering mode block was introduced for the first time at the station. In 2013, power stations of Donbassenergo broke the record over the years of independence, with the total index of production of 10 billion kWh.
After privatization tender, Energoinvest PrJSC Holding became the owner of shares of Donbasenergo PJSC in the amount of 60.77%.
Preparation for the implementation of the project of construction of new facilities, first in independent Ukraine, reconstruction of power unit No. 6 of the Slaviansk TPP with division into power units No. 6A and No. 6B with capacity of 330 MW each.
During the Siege of Sloviansk in spring 2014 Sloviansk TPP was destroyed to a great extent, all manufacturing facilities were broken down. Over 20,000 shells torn into the station territory. TPP has been being restored during nine months.
That same year “Donbasenergo” lost control over the part of its assets.
Despite all the difficulties, the company confidently looks to the future, actively makes progress and implements new world standards. In so doing, labour safety, environmental management, information security management system of “Donbasenergo” PJSC has received quality certificates. Currently the company is on the way of improving the processes related to long-term growth which will give an opportunity of already achieved results fixing.
