Management of other gas and dust pollution
Our ambition is to lower as much as possible emissions of pollutants generated during production processes, which is served by further infrastructural investments performed. Due to them, continued progress is possible with limiting emissions of sulfur dioxide, dust and nitrogen oxides.

ENEA Wytwarzanie
On 30 June 2020, the Kozienice Power Plant terminated its participation in the Transitional National Plan (TNP) and, as of 1 July 2020, complies with the emission standards stipulated in the IED, in effect from 1 January 2016. At the same time, the power plant completed a program for adjusting the installations to the BAT conclusions, which came into force on 18 August 2021. The requirements of BAT conclusions were implemented to integrated permits for three power installations for fuel combustion operating in the company – units 1-10, unit 11 and a start-up boiler house. The requirements considerably tightened the acceptable levels of emitted pollutions. No exceedance of the emission standards, threshold emission levels and other formal and legal requirements was found in 2021.
The power plant operates five flue gas desulfurization (FDG) installations, which guarantee the required reduction of SO2 emissions from flue gases of all units. All units are equipped with highly efficient electrostatic precipitators, which are upgraded on an ongoing basis in order to maintain high dust removal efficiency. All units (excluding unit 3) are also equipped with highly efficient selective catalytic NOx reduction (SCR) installations.
ENEA Elektrownia Połaniec
ENEA Połaniec Power Plant takes advantage of the derogation arising from the IED – natural derogation of 17,500 hours covering boiler 1.
Until the end of 2021, 15,327 hours were used in total from the limit of 17,500 hours, including 1,755 hours in 2021 (917 hours in Q1, 390 hours in Q2, 234 hours in Q3 and 214 hours in Q4 2021).
ENEA Ciepło
As part of the “Zachód” Heat Plant installation, ENEA Ciepło takes advantage of the heat derogation arising from the IED as regards SO2, dust and NOx emissions. In the period of validity of the heat derogation, i.e. from 1 January 2016 to 31 December 2022, emission standards as at 31 December 2015 are applicable.
ENEA Ciepło was awarded PreQurs certificate, class A described as “NE” (NO EMISSION) as well as the NO SMOG quality sign. This confirms that it produces heat in a more environmentally friendly manner than coal-fired home boiler systems.
