In the article an exergy analysis of technological schemes of mini thermal power plants with technologies of hybridization and combination was carried out. The first technology deals with a low-power hybrid station that uses both traditional fuel (natural gas) and renewable energy sources (solar energy). The second technology deals with the combined production of energy (thermal and electrical) and by-products - activated carbon, sulfur, ash and slag materials. The values of the exergy efficiency of the considered schemes are obtained. It was concluded that the use of hybridization and combination technologies allows to increase the exergy efficiency in comparison with the typical scheme for obtaining energy at distributed energy objects.
