Poland has a significant potential of geothermal energy. However, the high-temperature sources that are needed to drive power plants are found in relatively few places. Therefore, the objective of this paper is to consider any location in the northern part of Poland as a possible place to build a binary power plant. A scientific research was confirmed the existence of an elevated temperature gradient in this region. The hot rocks have an approximate temperature of 120 oC at depths of 3000 m. It was assumed that a hot brine emanates from these sources at a volume flow rate of 400m3/h and drives the Organic Rankine Cycle with isobutane as a working medium. The First Law thermal efficiency and the power output were estimated at 10.5% and 1.79 MWe, respectively. In addition, the Second Law thermal efficiency were calculated at 29.0%. All results were compared with the other binary power plants and they confirm that establishing the binary power plant in Poland would be thermodynamically justified.
