Maintaining the environmental balance is an integral part of DTEK’s successful business.
The Company is actively working to improve environmental conditions in the areas of its operation and preserve the environment for future generations. We are making strenuous efforts to minimize the negative impact on the environment at all stages of our production process, from coal mining and processing to electricity generation and distribution. These steps are fully in line with Ukraine’s aspirations to follow European trends in environmental protection.
Environmental activities at DTEK’s operations are based on DTEK’s Environmental Management Policy (revision 2.0) approved by DTEK CEO M. Timchenko on December 21, 2012.
DTEK is currently updating its Environmental Management Policy.
The Company’s 2030 long-term strategy sets the tasks in the area of environmental protection.
The Company pays special attention to environmental management issues. DTEK has a common environmental management system in place in compliance with the requirements of ISO 14001.
The environmental management system is part of the corporate management system and an important element of risk management. The consistent approach to environmental management at all companies of the Group using this system has a positive impact on DTEK’s competitiveness and investment appeal.
The benefits of ISO 14001 implementation are:
The ISO 14001 environmental standard has been being implemented at DTEK from 2008 to 2015. As a result, the Company developed unified corporate environmental protection requirements, identified environmental aspects and risks, and established an efficient system for managing them. This allowed us to build a sound basis for the Company’s further coordinated environmental protection efforts, use innovative environmental management methods and constantly improve the environmental performance of DTEK companies. Ninety percent of DTEK’s operations—thermal power plants, mines, processing plants, oil and gas producing facilities, and wind power companies—have already been certified for compliance with ISO 14001.
In September 2015, a new version ISO 14001:2015 was released, which allows three years for its implementation. The company has started to work towards implementing the new requirements.
The Company invests in upgrades of equipment and modernization of production processes in order to mitigate the negative environmental impact of its production activities. The key areas of DTEK’s focus are air protection (retrofit of electrostatic precipitators at TPPs), protection and sustainable use of water resources, protection of land and waste management (building ash dump dikes, promoting the utilization of coal combustion products, reclaiming waste dumps, etc.), optimized use of hazardous substances and materials, conservation of biodiversity, and others. DTEK’s total spending on environmental protection efforts in 2007-2015 amounted UAH 4.5 billion.
Ukraine’s full-fledged membership in the Energy Community means that energy producers are obligated to meet the requirements of Directive 2001/80/EC on the limitation of emissions of certain pollutants into the air from large combustion plants and Directive 2010/75/EU on industrial emissions (integrated pollution prevention and control). As DTEK is a leading company in Ukraine’s energy sector, this issue is among its environmental protection priorities.
As part of Ukraine’s fulfilment of its commitments under the Energy Community Treaty, in 2015, DTEK took part in working groups coordinating measures to reduce environmental pollution and implementing the requirements of European Directives 2001/80/EC and 2010/75/EU. These efforts include performance of the National Emission Reduction Plan for main pollutants from large combustion plants. Its implementation will make it possible to meet the requirements of European Directive 2010/75/ЕU for particulates and sulphur dioxide by 2028 and for nitrogen oxides by 2033.
In addition, as part of the Association Agreement between Ukraine, the European Union and its Member States, DTEK participates in the work groups under the Ministry of Environment and Natural Resources of Ukraine responsible for implementing the requirements of some other European directives in Ukraine’s legislation: Directive 2003/87/EC on the greenhouse gas emission allowance trading scheme; Directive 2008/98/EC on waste; Directive 2009/147/EC on the conservation of wild birds and Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora.
Particulate content in flue gases is reduced by an average of 22 times.
The general principle followed by the Company in managing water resources is their conservation and rational utilization. In order to optimize water consumption for process purposes, our generating companies employ recirculating cooling systems for their main and auxiliary equipment, recirculating hydraulic ash removal systems, and water recycling systems. Water consumption by the mining companies is rationalized through reuse of mine waters for process purposes and implementation of recirculating water supply systems at the coal processing plants. DTEK Energy’s distribution companies use water mainly for drinking and household purposes. Water is supplied from public utility networks. In order to ensure that it is used in a rational manner, we instruct our personnel and conduct timely inspections and repairs of shut-off valves.
In order to meet the requirements of the Environmental Management Policy concerning the reduction of discharged waste water and improving its quality, DTEK companies continuously monitor waste water quality and implement projects to upgrade treatment facilities, reuse waste water in their process cycles, and clean bottom sediments from cooling ponds.
Waste produced during the operation of DTEK companies is mostly (99.9%) made up of bulk waste products (rock, ash and slag), which are Class 4 non-hazardous waste. Increasing their utilization is one of the Company’s key tasks.
Thus, DTEK’s Coal Division designed a program to handle bulk solid wastes, which allowed us to analyze in detail the current state of waste dumps, assess risks relating to disposal of waste products at the dump sites for the period until 2030, and review alternative waste rock utilization options. In addition, we have made recommendations that will form the basis for the future coal mining waste handling strategy we intend to develop.
In an effort to step up the utilization of coal combustion products, all TPPs of DTEK’s Generating Division have developed and implemented programs to increase the use of fly ash, slag and other coal combustion products in 2012-2020.
As part of these programs, in 2015, we installed a dry ash removal system at DTEK Burshtynska TPP units 5 and 7, which allowed us to ramp up the utilization of coal combustion waste at our companies. The company rebuilt the access road used to transport dry ash from DTEK Dobrotvirska TPP.
One of the promising applications for TPP coal combustion products is road construction. To increase the re-use of coal combustion products, the Generating Division together with the Socially Responsible Business Association launched a joint project in 2015 aimed at increasing the utilization of coal combustion products in road construction. In 2015, the M.P. Shulgin State Road Research Institute developed Methodological Recommendations for the Use of Coal Combustion Products from DTEK Dobrotvirska TPP and DTEK Burshtynska TPP in Road Construction. Design documents and cost estimates were prepared for the construction of new road sections in the city of Novyi Rozdil using coal combustion materials. It is planned to build a 25.7 km-long road.
Much of DTEK’s coal reserves are located in the floodplain of the Samara River and its tributaries. Coal extraction under such conditions causes land subsidence, flooding and swamping. The relevant issues in this situation are rational utilization and protection of land resources.
The main steps taken to counteract the negative impact of mining activities in the Samara River floodplain are:
Along with land reclamation efforts, DTEK companies plant trees for compensatory purposes. Specifically, Coal Division companies planted 13 hectares of trees in 2015 to compensate for the damage caused to the forests by underground mining operations conducted at the Geroiv Kosmosu, Pavlogradske, and Ternivske Mine Groups of DTEK Pavlogradugol PrJSC.
Naftogazvydobuvannya PrJSC reclaimed 10.7 hectares of land using technical and biological methods in the vicinity of the newly drilled wells No. 11, 17, 23, and 70 in the Semyrenkivske field.
On October 1, 2011, DTEK joined the United Nations Global Compact initiative and started implementing the Green Office principles to reduce the environmental impact and promote a socially responsible behavior model among its employees.
The first stage of the project was implemented in 2011-2013 at DTEK’s corporate center in Donetsk. We launched separate waste collection for recycling purposes; set up parking places for bicycles; developed an e-training course called “DTEK’s Green Office”; and made and put up initiative bulletin boards for employees to see. In 2012, DTEK partially switched to buying eco-friendly office stationery and produced eco-friendly corporate products from recycled materials.
In February 2016, the project was launched at DTEK’s corporate center in Kyiv. In particular, we use adjustable heating systems and water and electricity metering devices here. We purchased Energy Star-rated energy-efficient office equipment. Measures were developed to cut down on paper use. We installed individual bins for separate waste collection and further disposal. There are initiative promotional bulletin boards and posters in the offices. We hold meetings of environmentally aware film fans and organize team building activities. The funds thus saved are channeled into DTEK’s social projects, for example, to buy trees as part of our annual Green City event.
We intend to have the Green Office principles implemented at all DTEK companies by 2020. During implementation, the project has evolved into a more extensive program called Lean Office, which aims at saving all possible resources. Rational ideas come from our employees. This approach has helped the Company achieve savings of millions of hryvnias. For instance, we cut down on international call costs by connecting to providers offering these services at lower rates. Automatic sleep and hibernation of desktops improved the energy efficiency at DTEK companies.
Incentives for resource-saving initiatives are provided by the Novator Continuous Improvement System that DTEK has been implementing since 2013. Its goal is to boost DTEK’s performance through the development of our employees’ potential, continuous improvement of our processes, reduction of losses, and perfection of product quality.
