Thermal power generation18 February 2019

In 2018, DTEK Group produced 27.2 mn tons of coal (-1.9% compared to 2017), supplied 34.8 bn kWh of electricity (-6.3%), distributed 43.7 bn kWh of electricity via grids (+1.2%), and produced 1 648.5 mn cubic meters of natural gas (-0.4%).

“Ukraine is currently going through a transformation process where the Energy Market Reform is one of the key components. We are proactively supporting the ongoing Reform and the past year was the year of structural changes for DTEK. We were the first electricity generation company who finalised the unbundling process, which allowed us to set clear objectives for each business. In particular, electricity distribution business is now to focus on providing uninterrupted electricity supply and electricity loss reduction; electricity supply business is to focus on improving of the quality of services as well as introducing new products. It is also important to note, that in 2018, we nearly doubled our investments into business development and reached UAH 20 bln. This allowed us to increase production of G-grade coal domestically and continue converting our generation units from A-grade to G-grade consumption, which in turn decreased dependence on import of anthracite coal. In 2019, we plan to significantly increase electricity output from renewable generation as we commission additional 500MW of wind and solar installed capacity. These are the specific actions and commitments undertaken by our business on its way of being transformed, where the whole industry is now heading. Partnership, professionalism and effectiveness is what we bring to Ukrainian energy sector with the aim of making it competitive, environmentally friendly, and independent from energy imports,” DTEK CEO Maksim Timchenko said when discussing the company’s operations.

Coal mining and processing

In 2018, DTEK Energy produced 24.1 mn tons of gas coal which is the highest annual production in the company's history. The volume of run-of-mine coal processing reached 17.2 mn tons, of which 2.4 mn tons were provided by independent CCMs. Concentrate output from the company's enrichment plants was 9.1 mn tons, and 1.4 mn from the third parties enrichment plants.

The main factors affecting coal production:

  • In the second half of 2018, all the company enterprises increased gas coal production. DTEK Pavlogradcoal output increased to 114.9 tons per person per month, and that of Bilozers’ka mine increased to 87.8 tons per person a month. This ensured coal production at a level of 24,131.5 thousand tons in the reporting term, which is 5.3% or 1,216.8 thousand tons more than in 2017;
  • Termination of anthracite production.

Key projects in 2018:

  • Equipment upgrade: 12 tunneling machines and 8 shearers were installed and 35 electric locomotives were upgraded at DTEK Pavlogradcoal mines. 3 tunneling machines and 2 shearers were installed at DTEK Dobropoliyeugol.

Construction of a ventilation shaft is underway at the Yubileyna mine, which will significantly increase the speed of freight and material delivery to the work site. In 2018, we completed construction of the battery room and built a lateral wagon tipper building.
  • Coal Processing Plant modernization: two new centrifuges were installed at DTEK Pavlogradskaya CPP, which allowed the plant load to be increased from 925 to 1,013 tons per hour while reducing chemical agent consumption. First equipment was shipped to the DTEK Oktyabrskaya CPP within the framework of the modernization project providing for heavy medium cyclone implementation. DTEK Dobropolskaya CPP is continuing the construction of a refuse dump. The project envisions bordering each dump level with clay, and constructing of an internal drainage system and a fire resistant protective layer. In 2018, a similar project was completed at DTEK Oktyabrskaya CPP. Project implementation reduces environmental burden by eliminating combustion source formation and the environment's contact with coal processing waste, while water will be discharged to a pond and then returned to the production.

Electricity generation

In 2018, DTEK Energy generated and dispatched 34.1 bn kWh into the Joint Energy System of Ukraine with. Power units running on gas coal grades produced 28.3 bn kWh, which is 4.4% or 1,185 mn kWh more than in 2017.

The main factors affecting electricity generation:

  • Reduced electricity generation by DTEK Skhidenergo, and Kyivenergo by 20.5% or 2,422.1 mn kWh due to termination of control of the Zuevskaya combined power plant in March 2017, and the end of concession to operate TPP-5 and TPP-6 (part of Kyivenergo) starting July 31, 2018;
  • Increased electricity generation by DTEK Dniproenergo and DTEK Mironivs’ka TPP by 3.8% or 373.4 mn kWh.

DTEK Energy is implementing a program aimed at increasing the use of G grade coal (gas coal) in order to minimize the use of imported anthracite coal. In 2018, electricity generation from the units running on gas coals increased to 28.3 bn kWh, which reduced the share of electricity generation from the units running on anthracite coal down to 12% in the total electricity generation.

Commercial activities

Coal exports

In 2018, 486.3 thousand tons of coal were supplied under export contracts, which is 35.0% lower than in 2017. All export operations are performed based at the Obukhovskaya Mine Group resource. The reduction resulted from an increased shipment to the Ukrainian market in order to minimize the anthracite deficit resulting from the termination of this coal grade production within the area controlled by Ukraine. 1.5 mn tons were supplied, which is 26.2% higher than in 2017.

DTEK Energy imported 2.2 mn tons of coal for heat generation, which is 2.7% less than in 2017. Coal was imported from the US and South Africa among other countries.

Coal shipment to industrial consumers in Ukraine remained almost the same as in 2017, i.e. 2,085 thousand tons.

Electricity exports

The company supplied 5.8 bn kWh under foreign trade contracts, which is greater by 16.5% compared to 2017. Electricity was exported to Hungary, Poland, and Moldova.

Natural gas imports and shipments on the domestic market

The volume of natural gas sales on the domestic market was 1.9 bn cubic meters. We were able to maintain the volume of trading operations at the last year level resulted from increased sales to the metallurgic sector enterprises, which compensated reduced demand from the energy sector enterprises.

DTEK Grids

In 2018, 43.7 bn kWh were distributed, which is 1.2% or 529.7 mn kWh more than in 2017.

The main factors affecting electricity distribution:

  • The increase of the volume of electricity distribution by DTEK Kyiv Electric Grids and DTEK Dnipro Electric Grids by 3.4% or 1,081.1 mn kWh was due to increased consumption by residential consumers and small businesses;
  • The reduction  of the volume of electricity distribution by DTEK Donetsk Electric Grids, DTEK HV Grids, and DTEK PES-Energougol by 4.7% or 551.4 mn kWh was due to a reduction in demand from industrial enterprises and suppliers at the unregulated tariff.

According to the Law On Electric Power Market, companies must effect unbundling, i.e. separate distribution system operator from electricity generation, transmission, and supply by way of establishing separate companies. These changes constitute the first stage of the energy market reform that is aimed at transitioning to the electricity market based on the European model.

DTEK Group effected system transformations of its operations. Kyivenergo, DTEK Dniprooblenergo, and DTEK Donetskoblenergo divided their operations according to the requirements.
