Energoprojekt-Katowice S.A. (EPK) is no stranger to heavy industrial and power plant design. Founded in 1949, the multidisciplinary engineering design firm has designed more than 100 power plants built in Poland and abroad, and is now the largest engineering company in Poland.

So when the Patnow-Adamow-Konin Power Plants Group – one of Poland’s largest producers of energy – began a complete rehabilitation project of the Patnow Power Plant in 2001, they naturally called on EPK’s expertise. The rehabilitation project was divided into six main parts. Foremost was the design and construction of a $480 million lignite-fired supercritical energy unit, capable of generating 460 megawatts of electrical power.

EPK was responsible for the basic and detail engineering designs of the steel and civil structures for this unit and, in particular, a boiler house contained within. Their designs involved modeling, space coordination, and static calculations such as structural and stress analysis.
