 abstract={Research on the technical and economic aspects of organic Rankine cycle (ORC) systems is of great relevance, showing potential for reducing environmental impacts and improving resource efficiency, which becomes critical in the context of the rapid global transformation towards sustainable and energy-efficient solutions. The purpose of this study was to investigate the existing systems in the field of ORC systems, including the technical and economic aspects of their application in small-scale power units. The study employed the statistical method, comparative method, and analysis. The study highlighted the key aspects of the application of ORC technology in small-scale power units. Substantial attention was given to economic analyses to identify factors affecting the competitiveness of technology in the field of small-scale energy projects. An economic study found high unit costs to be the main obstacle to the widespread adoption of the ORC in small-scale energy applications. This study also presented a technical review of the techniques for selecting the expander and working fluid. The analysis of these aspects revealed the main parameters affecting the efficiency and cost of the system. Optimization of the ORC to reduce unit cost was highlighted as a priority area for development, facilitating faster payback and widespread adoption of the technology. The role of the expander in the system and reducing the cost of high-speed power generators were also considered prominent factors for improving economic efficiency. The obtained findings may represent a valuable framework, enabling cost reduction in small-scale ORC systems and promoting the development of clean and economically competitive small-scale energy solutions.},
