The objective of this project was the reduction of emissions to the atmosphere.
The new installation for biomass co-firing has been put into operation in June 2009. It is integrated with two lignite fired fluidized bed boilers. This investment is PGE's another project resulting in reduction of emissions to atmosphere.

The investment was voluntary action of the company but influenced by EU/national regulations.
The project resulted in significant environmental (e.g. lower CO2 emissions), economic (e.g. power savings) and social (e.g. image improvement) benefits. Calculation of CO2 emissions reduction is based on chemical energy consumption during heat generation process. Average annual chemical energy (for 8 years of CCU exploitation) is on the level of 10.042.614 GJ.

The new heat and power cogeneration unit in Kielce CHP has been put into operation in December 2008. The unit consist of separated coal and biomass boilers and following devices: steam boiler OR 50, fuel: coal, steam production: 50 t/h; steam boiler OR 50, fuel: biomass, steam production 20 t/h; back-pressure turbine set, installed capacity: 10,5 MWe,
additionally heat station: 30 MWt.
Two separated steam boilers are working on one turbine. Applied technology is using BFU (BI-FUEL UNIT) technology. The new unit in Kielce CHP is very unique and the first one in Poland that enables to burn coal and biomass (energetic willow, wood chips) separately.

The objective of this project was to switch off two back-pressure turbine sets (T4, T5) integrated with combined cycle unit and to replace them by more efficient pass-out and condensing turbine (T6). Furthermore it is noteworthy that T6 turbine was primary integrated with high emissive coal fired boiler that has been shut down.

The objective of this project to carry out a renovation of district heating station implementing a CHP unit based on a gas turbine.
The project was executed in DHC Pleven, Bulgaria. It included instillation of a gas turbine and boiler-utilisator, after which the produced steam is fed to the existing main steam collector and feeds the respective steam turbine. A heat exchanger is installed at the outlet of the bolier-utilisator to utilize the heat of exhaust gases using water as a heat carrier. The overall capacity of the unit is 108 MW of which 32 MW electrical capacity.

LANXESS operates an adipic acid production plant at the industrial park in Krefeld-Uerdingen, Germany. Adipic acid production exists in Uerdingen since 1953 and the current installation is running since 1987. Adipic acid is used primarily as the main constituent for nylon production and is also used as carrier for fragrances, for the treatment of leather, in coatings, synthetic lubricants and fibres, photo chemicals, plastics and more.

By paying an eco bonus, the program of activities (PoA) encourages commercial and industrial customers to convert the existing heating systems running with fuel oil, coal or liquid gas to natural gas-fuelled heating systems.
The aim of the project is to reduce the GHG emissions by conversion to natural gas-fuelled boilers and direct heating systems as well as by the subsequent increase in efficiency. This leads to replacement of older, more emission intensive heating systems in favour of more environmentally friendly heating systems with natural gas-fuelled boilers and direct heating systems.

Power Plant Počerady 1200 MW is located in North-West of Czech Republic, close to border with Germany. It is one of the biggest coal-fired power plants in the Czech Republic. Its owner is ČEZ a.s., one of the biggest private utilities in Europe. PP Pocerady has six blocks, capacity 200 MW each. All of them are fired with domestic brown coal causing high level of emissions GHG, mainly CO2.
In June, 2009 ČEZ concluded a contract with ŠKODA PRAHA Invest. for the design, supply, procurement, erection and commissioning of a Gas Turbine Combined Cycle (GTCC) powerplant capacity 841 MW. to be built in Pocerady. Its construction will start early 2010. Development of this GTCC plant will be in progress in the period from October 2010 to April 2013. Project costs are of the investment amounts approx 800 Mill. EUR.
