Compliance with EU guidelines

According to the EU Directive 2010/75/EU on industrial emissions (IED), from 1 January 2016, more stringent emission standards have been introduced. We had been preparing for this for many years by investing in the modernization of installations to reduce emissions of oxides of sulphur, nitrogen and dust. Now, we face the next phase of works aimed at minimizing emissions to air.

Kozienice Power Plant acceded to Interim National Plan within the SOand dust emissions which shall be valid until 30 June 2020.

The emission of gases and dust

In 2015 in Kozienice Power Station:

For the reduction of sulphur oxides: we launched the fourth installation of flue gas desulphurisation

For the reduction of nitrogen oxides: we installed a catalytic denitrification station (SCR) of exhaust in 4 blocks of 200 MW (with achievable concentrations below 100 mg / Nm3). Denitrification systems are designed to provide approx. 80% reduction of nitrogen oxides in exhaust gases.

For the reduction of dust emissions: we provided the possibility of a two-stage extraction thanks to high-performance electrofilters and flue gas desulphurization installations.

For the period 2016-2018 in Kozienice Power Station, we plan to build the same installation in the remaining three blocks of 200 MW and two blocks with a capacity of 500MW.

On the other hand, CHP Bialystok has been gradually upgrading its transmission networks and heat distribution in order to improve the efficiency of heat supply in line with the assumptions contained in the “Plan for the development of district heating in Bialystok for the years 2013-2018”. The upgrades affect both the level of energy consumption and the reduction of greenhouse gas emissions.

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

Important investments

BIAŁYSTOK: 27.7 million PLN was spent on the installation, which recovers heat from exhaust gases from the combustion of biomass in CHP Bialystok. This is the first installation on such a large scale in Poland. Our commitment to the environment was appreciated the Swedish Ambassador for Ecology Jan Olsson. During the scientific and technical symposium in Bialystok devoted to the latest environmental investment of Enea, he drew attention to the great importance of Polish - Swedish cooperation in this innovative project.

The technology used for heat recovery from the exhaust gases can increase heat production from biomass boiler without additional fuel consumption. Thanks to the investment in a modern heat recovery system, Enea Wytwarzanie significantly reduced emissions into the atmosphere and increased its productivity. The estimated reduction of carbon dioxide emissions amounts to approx. 20,000 tonnes per year.

PIŁA: The co-generation power plant built in MEC Pila is one of the most modern plants of this kind in the country. It can produce approx. 10 MWh of heat and approx. 10 MWh of electricity.  It is powered by natural gas.

Its launch reduced the need for energy from conventional sources contributing to the reduction of the amount of burned carbon, emissions of dust, sulphur oxides and CO2 to the atmosphere.
