Аннотация: The relevance of the work is caused by the necessity to execute the Federal law «On energy saving and on increasing energy efficiency and on amendments to certain legislative acts of the Russian Federation» and is aimed at reducing the cost of production of electric and thermal energy in the Northern areas of the decentralized power industry of Russia. The aim increase of energy efficiency of thermal energy production due to the modernization of coal-fired boiler houses, justification of the choice of an alternative option for the development of technology that allows the conversion of thermal energy into electrical energy in areas of decentralized energy. Creation of installations competing with diesel power stations for the generation of thermal and electric energy, increasing the economic efficiency of energy production in the northern regions of Russia. Research methods: analysis of existing technologies for production of thermal energy in the areas of decentralized energy sources; thermal, techno-economic analysis of technologies to convert low-grade thermal energy into electrical energy; modelling the plants based on organic Rankine cycle using a software package Smoweb; analysis of contemporary producing technology of Organic Rankine cycle in order to select the most appropriate one. Results. The authors have carried out the comparative analysis of existing technologies for production of thermal energy in the areas of decentralized energy sources and chosen the most effective option for increasing energy efficiency. Heat produced and techno-economic analysis of using technologies to convert low-grade thermal energy into electrical energy was carried out. The authors modeled the device working on the principle of organic Rankine cycle for electric power of 10 kW. The manufacturers of the devices, working on the principle of organic Rankine cycle, were analyzed.
