To produce electricity and heat, TAURON Group companies use various commodities: renewable (biomass) and non-renewable (hard coal, natural gas and heating oil) as well as water (surface water, underground and municipal water).

Hard coal is the TAURON Group’s main fuel, just as is the case across Poland. To a lesser extent energy is produced using water and biomass. The Group has, in total, 20 biomass co-burning units (19 in TAURON Wytwarzanie, one in TAURON Ciepło) and three dedicated biomass units, (two in TAURON Wytwarzanie and one in TAURON Ciepło). In biomass boilers, „forest” biomass (chips, pellets and sawdust) and „agro” biomass (biomass from fuel crops and pellets) are used.

Water management in the TAURON Group is considered from various perspectives since companies use water for various purposes. Power plants and combined heat and power plants use water mainly in cooling processes. Coal mines need it to process coal. Hydroelectric power plants use it to generate energy.

000018

Both mines in TAURON Wydobycie hold water law permits for the rational management of water resources – the decision of the Marshal of the Region concerning intake and discharge of underground water to surface water courses in which levels of permissible pollutants of discharged water are defined. The basic parameters defined in the permit include the permissible quantity of chloride, sulphate ions and suspension. Mines endeavour to comply with the standards required according to the provisions of the decision.

The power plants in TAURON Wytwarzanie extensively protect water resources protection by generating energy generation with highly efficient generation units, using closed water circulation, limiting water consumption through utilisation of industrial wastewater for circulation with lower qualitative requirements and continuously monitoring the quantity of water intake. Moreover, power plants belonging to TAURON Wytwarzanie have integrated management systems confirming that their environmental management standards comply with international norms: ISO 9001, ISO 14001 and PN-N-18001

The main sources of water intake for Group companies include rivers, underground water and municipal water. In the TAURON Group, TAURON Wydobycie, TAURON Wytwarzanie, TAURON Ciepło consume the largest quantities of water.

In order to limit water intake from the watercourse for technological needs and eliminate post-cooling sewage, the Czatkowice limestone mine has started to modernise the cooling system for its primary crushers. In 2015 the company prepared a technical design and submitted it to the Design Office for implementation.

Completion of modernisation is scheduled to transpire in Q2 2016. This project has received a promise for a loan from the Regional Environmental Protection and Water Management Fund in Kraków.

All companies treat wastewater in their own installations, using mechanical, mechanical and biological methods.

Limiting the quantity of discharged wastewater and improving quality in the power plants of TAURON Group is done through the distribution sewage network and production wastewater treatment, including rainwater from sludge and oil prior to discharge into the surface water, use of industrial wastewater for circulation with lower qualitative requirements, treatment of wastewater from technological processes in the company wastewater treatment system and building pre-treatment and protective installations in facilities posing a particular threat of environmental contamination.

Wastewater management is subject to monitoring entailing measurement of the quantity of wastewater discharged during a day, sampling wastewater and measurements of wastewater quality performed at regular intervals. Internal EMAS audits verify the adequacy of waste treatment and wastewater management.

Under wastewater management, the TAURON Group’s coal mines are taking measures to limit the quantities of mine water through its use for the plant’s own needs and by limiting the discharge of salt loads by mining methods, by retaining salty water in excavations using dams. Moreover, in 2015 the company ran a research project on mitigating the concentration of harmful Cl+SO4 compounds, through construction of a retention and dosing reservoir in which mine water will be retained and discharged, depending on the chemical status of surface water (in the Vistula river).

Self-management of sewage generated in hydroelectric power plants EW Pilchowice I, EW Złotniki, EW Leśna, EW Bobrowice I and EW Bobrowice III, in accordance with environmental quality standards was the main incentive for TAURON Ekoenergia to build and operate a local mechanical and biological sewage treatment plant. These wastewater treatment plants are subject to technological surveillance by a specialised third party to ensure the reliability of the treatment plant’s equipment,

control and regulation of the wastewater treatment process, identification and designation of the method to remedy potential failures and current maintenance instructions for employees. In 2015 regular tests of treated wastewater discharged to waters were performed, the failures encountered by the treatment plants at EW Pilchowice I and EW Złotniki were remedied and new water law permits were obtained to discharge treated sewage in EW Bobrowice I and EW Bobrowice III into the water.
