Segment of System Power Plants
Pursuant to the IED directive, since 1 January 2016, stricter pollutant emissions standards have been in force. Satisfaction of the requirements of IED directive in Kozienice Power Plant is guaranteed by the current and previously realised numerous investments and modernisations. Additionally, in order to minimise the risk of breach of the stricter standards for emissions to the air the Power Plant joined the Transitional National Plan within SO2 and dust emissions (in force until 30 June 2020), and has been applying the treaty derogations within NOx emissions (in force until 31 December 2017).
In order to reduce nitric oxides emissions, a gradual construction of the installation of the catalytic denitrogenation of flue gases - SCR - has been performed since 2013 in Kozienice Power Plant. Currently, units No 1, 2, 6 and 7 have SCR installations. The last installation of this type will be built in 2018 for unit No 10.
In 2015, another, already the fourth flue gas desulphurisation installation - IOS IV was commissioned. Along with IOS I, IOS II and IOS III installations it constitutes a guarantee of desulphurisation of all the flue gases in relation to the installed capacity of the Power Plant’s units.
Relevant exploitation of the existing electrostatic precipitators, and also their gradual replacement with new ones, highly efficient units with the second stage of dust removal guaranteed by the used flue gas desulphurisation installations ensure satisfaction of the dust emission standards in force since 2016. In 2017 the replacement of the electrostatic precipitator of unit No. 9 is planned.
Pollutant concentration in Kozienice Power Plant in 2015
- SOx concentration was by 15% lower than the acceptable concentration
- NOx concentration was by 24% lower than the acceptable concentration
- Dust concentration was by 56% lower than acceptable concentration

The implemented investment activities in order to reconcile to the requirements of the Directive No. 2010/75/UE regarding industrial emissions (IED) – Kozienice Power Plant
|Unit||Current generating capacity (MW)||Denitrification installation (compliant with IED < 200 mg/Nm3)||Desulphurisation installation(compliant with IED < 200 mg/Nm3)||Dust(compliant with IED < 20 mg/Nm3)|
|B1||215||√||50% of attainable capacity covered with IOS operation||100% of attainable capacity covered with IOS operation|
Within the requirements specified by the IED directive, and also BAT conclusions planned for implementation (cBat) – Enea Wytwarzanie has been realising, consistently for several years, the specified schedule of adaptation investment activities.
In 2015 the following occurred in Kozienice Power Plant:
- the fourth flue gas desulphurisation plant (IOS) was started which along with the other installations guarantees desulphurisation of 100% of flue gas with the concentration much below 200 mg/Nm3
- an installation of the catalytic denitrogenation of flue gases (SCR) was installed on four 200 MW units (with concentrations below 100 mg/Nm3), so that to significantly reduce nitric oxide
- high dust reduction efficiency was achieved due to two-stage removal of dust guaranteed by highly efficient electrostatic precipitators and flue gas desulphurisation plants
During 2016-2018 it is planned to build installations on the other three 200 MW units and two 500 MW units
Installation until 2018, of the SCR plant, and also currently used IOS installations, provide the Company with a possibility of satisfying the requirements of IED directive and future cBAT.

Segment of Heat
Enea Wytwarzanie - segment of Heat (Białystok Heat and Power Plant) has realised the following investment until now which affect the volume of emissions:
- conversion of coal-fired OP-140 boiler No. 5 to biomass fluidised bed OFB-105
- conversion of coal-fired OP-140 boiler No. 6 to biomass fluidised bed OFB-105
- SNCR installation of flue gases denitrification on OFB-105 boilers No. 5 and 6
- SCR installation of flue gases denitrification on OP boilers No. 7 and 8
- heat recovery system on K6 boiler
Currently, the flue gas desulphurisation plant is being installed for OP-230 boilers No. 7 and 8 - date of completion 2017.

Issues relating to the segment of mining - LW Bogdanka
Protection of atmospheric air
- LW Bogdanka does not hold any organised emission source emitting dusts and gases to the atmosphere
- The heap of gangue is a non-organised source which may emit dusts on dry and windy days
Water and waste water management relates mainly to underground water, including:
- draining of formations in the area of mining excavations
- controlled drainage of Jurassic layers
- economic use of water for fire protection and technological purposes
- pumping-up water to the surface
- economic use of underground water on the surface (Zakład Przeróbki Mechanicznej Węgla, Łęczyńska Energetyka sp. z o.o.)
- underground water retention in reservoirs on the surface in order to reduce the suspension
- water drop from reservoirs through Rów Żelazny to the Świna River in the volume of ca. 15,776 m3/day
- underground water characterises with the total chlorides and sulphates in the amount of 968 mg/dm3
- In 2015 the total revenue of mining waste amounted to 4,971,527 tonnes
- Around 53% of waste was recovered and managed. The waste recovery, i.e. use for land rehabilitation, road hardening, cement production in Cementownia “Ożarów” and other numerous goals amounted to - 2,649,322 tonnes
- 97% of waste is used for the degraded land reclamation It consists in restoring lands to their original shape through filling post-sand excavations with mining waste and then covering them with a soil layer and development to rural or forest areas
- The other mining waste (2,322,205 tonnes) are dumped in the mining waste neutralisation plant in Bogdanka. LW Bogdanka performs the management of other post-industrial waste (scrap metal, waste wood, used oils, etc.) and submits for neutralisation this waste which cannot be used (used up sources of light, conveyor belt walls, packaging of adhesives, paints, etc.)
- In 2015, no land-reclamation works were performed on post-industrial areas
- The maintenance of the organised green areas, of the mining waste neutralisation plant and post-industrial areas recultivated in previous years in the region of Bogdanka, Nadrybie and Stefanów Fields and railway facilities is performed on a continuous basis
- The impact of the mining exploitation in 2015 on the surface was visible, as so far, mainly in the form of increasing surface reach of the existing impacts
- In the region of Bogdanka and Nadrybie Wieś the maximum subsidence remains on the level of 5,00 m in the central part of the subsidence basin
- The damage in the buildings in 2015 - as so far - in most cases related to the rural developments, the reported damages in these buildings posed no danger to users and were removed on a continuous basis
- The costs of removing damage caused by the mining exploitation in 15 amounted totally to ca. PLN 5.04 mln
Sanctions and fees faced by the Company due to environmental protection
- The mining operations entail the exploitation fee due to the use of the natural environment and a range of costs related to:
- post-mining waste management
- post-industrial land rehabilitation
- environmental monitoring
- development of surveys and documentation necessary for the plant operation.
- The exploitation fee is paid every six months to the accounts of the municipalities the territory of which is exploited (60%) and for the National Fund of Environmental Protection and Water Management (40%). The licence fee constitutes also in 40% the income of the National Fund of Environmental Protection and Water Management and in 60% the income of mining municipalities.
- LW Bogdanka satisfies the standards within ecology and in 2015 did not pay any penalties for the breach of the conditions of using the natural environment specified in the laid down in the legal provisions in force
