[G4-14] We are aware of the impact our operations have on the environment. For this reason, the companies from the Group are taking several actions – whether required by national or EU regulations or the actions that are not stipulated in any provisions of law – to reduce such impact. Environmental aspects are of particular importance to our power plants, CHPs and mines which have greater impact on the environment than our other companies.

[G4-EN31] In 2016, the TAURON Group’s total expenditures on investments related to environmental protection amounted to more than PLN 72 million, and total expenditures associated with environmental protection were more than PLN 355 million.

The Business Areas have been conducting pro-environmental activities for many years. The best evidence for this is the Siersza power plant, the first commercial power plant in Poland to implement the environmental management system according to PN-EN 14001 standard (in 2000). In subsequent years, it was joined by more production plants which are currently comprising the Group.

[G4-34] In 2016, the Environmental Protection Team was established in TAURON. Its tasks include comprehensive management of environmental protection matters in the entire Group, in collaboration with the persons responsible for this area in individual companies. One of the Team’s tasks for the nearest future includes drafting the environmental policy for the entire TAURON Group.


Efficient management of resources

[EN-DMA] In electricity and thermal generation, TAURON Group companies use renewables (biomass, hydro and wind) and non-renewable sources (hard coal, natural gas, heating oil).

Hard coal is the main fuel among the TAURON Group’s energy sources. The Group uses renewable energy sources, such as water, wind and biomass, to smaller extent. The Group has a total of 20 power units with biomass co-firing capacities (19 in TAURON Wytwarzanie, 1 in TAURON Ciepło) and 3 biomass-only-fired units (2 in TAURON Wytwarzanie and 1 in TAURON Ciepło). Biomass boilers are used to burn “forest” biomass (such as logging by-products and sawdust) and “agro” biomass (biomass from plants grown for energy purposes).

[EN-DMA] Water management in the TAURON Group is examined from various perspectives because the companies use water for different purposes. Power plants and CHPs use water mostly in cooling processes, and mines use it in coal enrichment processes. On the other hand, hydropower plants use it directly to generate power.

The main sources of water for the Group companies are surface waters. The most water is consumed by TAURON Wytwarzanie, TAURON Wydobycie and TAURON Ciepło.

Efficient management of water resources is bringing about the expected outcomes. In 2016, the TAURON Group companies used over 15% less water than in the previous year.

* Industrial water – treated liquid waste, water drained from sand quarry.

[G4-EN22] All the companies discharge liquid waste in accordance with the prevailing regulations: by treating liquid waste in their own installations or discharging it into external grids.

The quantities of liquid waste discharged from the TAURON Group’s power plants are reduced through usage of industrial liquid waste in the circuits with lower requirements in terms of quality.

In addition, the TAURON Group’s mines are taking the actions aiming at reducing the quantities of underground waters discharged to rivers through using such waters for in-house needs of the mining plants, in the circuits with lower requirements in terms of quality, and through mechanically restricting the discharge of water with higher salt concentrations using the so-called mining methods, i.e. retention of such waters in the pits by dams.

The liquid waste management system is covered by monitoring which includes measurements of quantities of discharged liquid waste and measurements of its quality, performed in regular time intervals. In addition, certain plants carry out internal audits as part of EMAS or ISO systems, which additionally verify the implementation of liquid waste management policies.

Waste management is an important issue in the TAURON Group. Management of large quantities of waste produced by power plants, CHPs and mines puts a significant strain on the environment and results in costs incurred by the Group. For this reason, individual companies undertake various initiatives aiming at optimizing the waste management processes. The leaders in this area are TAURON Wydobycie and TAURON Wytwarzanie, which produce the greatest quantities of waste.

As a result of measures taken, the quantities of waste sent to landfill by the TAURON Group are decreasing and its reuse rates for market purposes are improving.

GOOD PRACTICE - Usage of byproducts of mining processes

Since 2010, TAURON Wydobycie has been carrying out technical and organizational activities aiming at improving the quality of aggregates extracted from gangue which accompanies hard coal deposits. Through selection of adequate fractions of gangue and their proper mixing with selected ashes, aggregates and aggregate-adhesive mixtures are obtained, which meet the requirements of materials that can be used in road construction and hydrotechnical structures (e.g. flood banks and levees). Recently, the investments of public purpose have been TAURON Wydobycie’s strategic and leading direction for usage of mining byproducts. In such investment projects, aggregates are used in construction of public purpose facilities such as leisure, sports, educational, cultural and resting facilities. The construction of such facilities may stimulate sustainable development of the regions by harmoniously combining the industry with environmental protection and by supplying recreation and leisure to local communities directly or indirectly connected with the operations of TAURON Wydobycie’s mines.

We invest in environmental protection projects

[EN-DMA] In the TAURON Group, the issues concerning environmental protection are looked at from several dimensions.

According to our approach, minimization of the Group’s impact on the environment consists not only in reduction of emissions and pollution from the firing processes but also utilization of waste, increasing energy efficiency, management of water and materials as well as environmental monitoring.

For this reason, every year, investments related to environmental protection have a significant share in the Group companies’ budgets. In 2016, we spent over PLN 72 million on such projects. What’s important is that we do not focus only on short-term and immediate activities – we also undertake longstanding pro-environmental research and development projects.

[EN-DMA] The problem of carbon dioxide emissions and emissions of other greenhouse gases is one of the key issues discussed at the European Union level. Because the TAURON Group’s energy mix is based primarily on hard coal, we pay particular attention to the matters concerning CO2 emissions and the risks associated therewith.

Pursuant to the Act on greenhouse gas emissions trading system, the TAURON Group’s power plants and CHPs are obligated to monitor their production installations from the standpoint of greenhouse gas emissions and draft annual reports in that regard. The aforementioned reports are subject to mandatory verification by an independent institution.

The vast majority of carbon dioxide emissions to the environment in the TAURON Group comes from burning its basic fuel, i.e. hard coal. Moreover, settlements include emissions attributable to burning of mazout as well as CO2 generated during exhaust desulfurization process (as a result of release from sorbent).

In 2016, the entities belonging to the TAURON Group emitted 14.9 million tons of CO2 – 1.4 million tons less than a year before.

[G4-EN21] Production of energy from fossil fuels also involves emissions of other pollutants, in particular sulfur and nitrogen compounds as well as dusts. Their permitted values are closely regulated and are steadily becoming more stringent. The most recent significant change in this area took force on 1 January 2016. The TAURON Group’s production entities are equipped with state-of-the art systems and installations that allow to minimize emissions (e.g. exhaust gas desulfurization and denitrogenation installations, highly efficient de-dusting installations), and the 910 MW unit in Jaworzno, which is currently under construction, will meet even more rigorous emission standards than the currently prevailing ones.

Air emissions are calculated using data from the emission monitoring system (these systems are subject to obligatory verification), results of periodic measurements and use of emission indicators.

In addition to these risks, climate changes will affect the revenues of TAURON Sprzedaż and TAURON Dystrybucja – change in electricity demand influences electricity volume and prices (sales) and the level of revenues from the sale of distribution services (distribution). In the case of TAURON Dystrybucja, climate changes causing violent storms, windstorms and precipitation may influence the grid failure indices, causing power cuts and leading to the necessary expenditures to repair them.

We educate the stakeholders on environmental protection

Our care for the environment manifests itself not only through conducting the business activity on the basis of principles of sustainable development but also through sense of responsibility for educating the community in pro-environmental spirit.

For this reason, the TAURON Group companies are organizing the informational and educational activities dedicated to environmental protection and to conservation of natural resources and energy. They are organizing educational visits to the Group’s plants that have implemented state-of-the-art technologies to minimize the impact on the environment. Our campaigns are intended for customers, local communities, and, primarily, children and youth, where the eduction on pro-environmental behaviors is particularly important in the context of the coming decades.

GOOD PRACTICE - Open days in ZW Katowice

In cooperation with the city of Katowice, TAURON Ciepło organized the campaign among the residents to promote energy saving. One of the attractions of the Katowice City Energy Days was a trip to ZW Katowice CHP during which visitors could take a tour of the plant with a guide and learn how thermal systems operate. In the International Cultural Center, students of high schools with profiles related to power industry and environmental protection participated in the educational and training seminar which was attended by representatives of innovative production and service enterprises from the region. During the educational panel and at the promotional stand, TAURON Ciepło made a presentation to the students about the company’s operations as well as innovations and directions for development in the heat generation industry.

GOOD PRACTICE - TAURON Ekoenergia’s nature hall

Social campaign addressed at elementary school students from TAURON Ekoenergia’s area of operation. The campaign aims at selecting 5 winning schools that will receive the same financial award earmarked for organizing the nature educational hall named “TAURON Ekoenergia’s nature hall”. In 2016, the 6th edition of the campaign was held, which resulted in opening 5 new nature halls. In order to obtain funds for equipping the hall, the students prepared contest works in the form of a poster with a slogan that promotes TAURON and production of power from wind and solar sources. Through involvement in the campaign, the children learn that they have a real impact on the surrounding environment. The state-of-the-art TEE Nature Hall enables the students of subsequent classes to gain not only theoretical but also practical knowledge. Overall, there already are 29 TEE Nature Halls on the area of the company’s operations.

GOOD PRACTICE - Campaign entitled Don’t be a second-hand smoker

The Don’t be a second-hand smoker campaign, which is conducted in Katowice and Chorzów, includes, among other things, diagnostic tests of lungs, distribution of educational materials discussing the problem of household furnace emissions, distribution of masks on smog days as well as informational and educational stands. The campaign is a follow-up to the Big risks of household emissions campaign, which was carried out in 2012 and was one of the first campaigns to emphasize that problem. According to the 2011 survey, in the Silesian and Dąbrowa metropolitan area, as many as 40% of the residents who heat their homes on their own use trash for this purpose on a regular basis. Thanks to social campaigns and the growing involvement of the media, non-governmental organizations and local government authorities, the awareness of the problem is increasing. We believe that this will translate into specific actions leading to the elimination of obsolete heating installations.
