Zuevskaya thermal power plant is a large enterprise in the southeast of the Donetsk region. Included in the structure of the interdisciplinary combined company DTEK Vostokenergo. The latter includes 10 TPPs, 31 coal mines and 13 mine departments, 7 enrichment plants, the largest wind farm in Eastern Europe, 2 oil and gas companies.
History of Zuevskaya TPP
In the 80s, the rapid development of the Donbass industry required additional energy capacities. Given the richest deposits of coal of various grades in this territory, the Soviet government decided to build a number of power plants using local types of fuel.
In particular, forty kilometers east of Donetsk, the construction of a large TPP, the Zuevskaya State District Electric Power Station No. 2, began. The city of Zugres gradually grew around the industrial facility, in its name repeating the abbreviation of the station.
ZuGRES-2 (Donetsk region, Ukraine) at the end of the Soviet era included 4 power units and had a capacity of 1175 mW. Subsequently, the TPP was privatized, renamed and became part of the assets of businessman Rinat Akhmetov, who owns a stake in Vostokenergo.
The conflict in the Donbass led to a partial loss of parent company management over Zuevskaya TPP. In March 2017, the DNR authorities demanded to re-register ZuTES and take an inventory. In fact, this means the transfer of the station under the control of the DPR government. Vostokenergo is looking for ways to resolve a non-standard situation. During the three years of confrontation, DTEK was able to maintain the enterprise’s operability, providing uninterrupted electricity to consumers in Donetsk and other areas.
Energy production
Zuevskaya TPP operates on the so-called coal of gas brands. Raw materials mined in the coal mines of Donbass are supplied by related divisions of the parent company DTEK. Key operational indicators of DTEK ZuTES, million kWh:
| 2012 | 2013 |
Power generation | 5270 | 6575 |
Spending on own needs,% | 7.5 | 7.2 |
Electricity supply | 4875 | 6100 |
Structure
Zuevskaya TPP has four power units with a combined capacity of 1245 MW. The first two were launched in 1982, in 2009 and 2008, respectively, were reconstructed to meet modern production and environmental requirements. Power unit No. 3 was commissioned in 1986, and No. 4 in 1988. All of them underwent modernization with a simultaneous increase in capacity.
Specifications:
Block number | Enter | Overhaul | Power increase | Total power | Operating time |
1 | 1982 | 2009 | at 25 mW | 325 mW | more than 186000 hours |
2 | 1982 | 2008 | at 20 mW | 320 mW | more than 182000 hours |
3 | 1986 | 2006 | | 275 mW | more than 164,000 hours |
4 | 1988 | 2012 | at 25 mW | 325 mW | more than 151,000 hours |
The reconstruction of the third unit, planned for 2014/15, has been suspended with an increase in power by 25 mW.
Modernization
In 2013, DTEK Vostokenergo allocated 2486 million hryvnias for the reconstruction and technical re-equipment of power units of thermal power plants. Modernization allows to extend their service life by 10-15 years, increase power and range of maneuverability while reducing specific fuel consumption. Since 2012, DTEK during the reconstruction of power units has been upgrading electrostatic precipitators in accordance with Directive 2001/80 / EC.
In particular, by January 2013, power unit No. 4 of the Zuevskaya TPP was modernized. After reconstruction, it is connected to the power system of Ukraine. Updating the equipment allowed to increase the reliability of its work and significantly reduce polluting emissions. Investments in the repair of the power unit amounted to 252 million hryvnia.
Environment
Donetsk region (Ukraine) is a powerful mining and production cluster, whose enterprises cause significant damage to the region’s ecology. DTEK makes significant efforts to minimize the negative impact on the environment at all stages of the production process. To maintain the ecological balance, the company is modernizing production, which will ensure the reliability of energy supply and compliance with European environmental standards.
As a result of reconstruction of electrostatic precipitators at power unit No. 4 of DTEK, Zuevskaya TPP reduced the dust concentration in air emissions from 317.4 mg / nm 3 to 44.2 mg / nm 3 . It is planned to reconstruct other operating power units with the installation of block and station desulfurization of various types, bag filters as part of semi-dry desulfurization, non-catalytic and combined nitrogen purification. As part of the project to build a section of road between the city of Zugres and the solid waste landfill using ash and slag from the Zuevskaya TPP, a technology has been developed for using ash and slag materials from ZuTES in road construction.
Conclusion
Zuevskaya TPP continues to work in difficult conditions. Only one of the four power units operates regularly. At the same time, the station remains a large (in some areas - the only) generator and supplier of electric energy in the Donbass.
