Construction of the new 1,075 MW power unit at Enea passed the first major test

The high-performance power unit being built at the Kozienice Power Plant will have a capacity of 1,075 MW, with an efficiency level of approx. 46%. Enea Group has invested over 5.1 billion Złoty (around 1.21 bln Euro) in the project.
"The new unit of the Kozienice Plant will become an important pillar for the Polish energy security. At the same time it will be one of the most efficient facilities of its kind in the world", says Miroslaw Kowalik, CEO of Enea. "This investment shows that there is a place for modern, high-efficient and low-emission conventional power plants, which are using cutting-edge technologies to produce energy based on coal, in an environmentally friendly manner."
The foundation stone for the power plant's new unit (Kozienice 11) was laid on 21 November 2012. The Mitsubishi Hitachi Power Systems Europe Group has supplied the utility steam generator (boiler) and some balance-of-plant. The steam turbine, generator and associated components as well as the flue gas cleaning equipment come from Japanese parent Mitsubishi Hitachi Power Systems, Ltd. Consortium partner Polimex-Mostostal is responsible for the building component and its erection as well as for most of the balance-of-plant.
"Construction of Kozienice 11 was MHPSE's first step in accessing the Polish power plant market", according to Rainer Kiechl, CEO of the MHPSE Board of Directors. "Since then we have acquired a further order for constructing the utility power plant at Turow and are also participating in other bid invitations. Poland is clearly a key market for our company and the trouble-free collaboration with customer Enea is an important reference for us".

This is something echoed by Yasuo Fujitani, Director and Senior Executive Vice President of Japanese parent Mitsubishi Hitachi Power Systems, Ltd.: "MHPS not only designs and builds gas and coal-fired power plants but also supplies, for instance, state-of-the-art flue gas cleaning technologies. These components will become increasingly important in Poland and in other countries of central and eastern Europe".
Kozienice 11 is also a prime factor for the economy and the companies involved in its construction. "A considerable share of the value created remains in the region with sub-contractors and other participating firms", stresses Antoni Józwowicz, CEO of Polimex-Mostostal S.A.
At the boiler pressure test the finned tube walls, heating surfaces and piping of the 100 meter high utility steam generator were filled with water and tested for seal tightness at a 513 bar pressure. Over 93,000 welds had to withstand this extremely high pressure. Confirmation of such has come from the Polish UDT notified body, which is the counterpart to Germany's TÜV. Currently almost 2,450 workers, engineers and other specialists are at work on the project site.
