This paper presents energy and exergy analysis results of whole gas turbine set and all its components. From the energy viewpoint, combustion chamber has the lowest energy loss (21.31 MW) and the highest energy efficiency (97.20%) of all gas turbine set components. Exergy analysis shows totally opposite trend in comparison to the energy analysis. From the exergy viewpoint, turbocompressor and turbine have low exergy destruction (both around 12 MW) and very high exergy efficiencies (92.43% for turbocompressor and 96.12% for turbine) at the base ambient state. Simultaneously, at the base ambient state combustion chamber has an exergy destruction of 159 MW and low exergy efficiency of 73.29% only. The combustion chamber is the most sensitive to the ambient temperature change of all components from the gas turbine set – the ambient temperature change of 10 °C will result with combustion chamber exergy efficiency change of approximately 0.67%. Whole gas turbine set (plant) has an energy efficiency of 34.40% and exergy efficiency of 33.08%.

It is established that the activity of industrial enterprises in conditions of instability of the economic situation in the country, political situation, deterioration of the welfare of the population, imperfection of the current legislation, increase of tax pressure, that is external factors of activity, is aimed at strengthening of competitive positions by penetration a new market segment, production of innovative products, reduction of costs, rational use of resources, under the condition of implementation of technological advances.
It is determined that the level of innovation activity of enterprises is characterized by a gradual deterioration, since scientific and technological achievements are rather slowly used, manufactured products, based on the use of innovative developments, are not in demand on the foreign market, because it is uncompetitive along with the products of leading enterprises. It is substantiated that there are no favorable conditions for rising the innovation activity of industrial enterprises, since most of them are in crisis or unprofitable, not provided with sources of financing for attracting innovative technologies, sharing experience with international organizations. It is proved that the solution of these problems is the implementation of the innovation policy of industrial enterprises, which is possible under the conditions of formation and use
of economic mechanism of innovation activity (EMIA). Elements of organizational and economic mechanism of innovative activity and innovative development of industrial enterprises are proposed under condition of formation of innovation policy.
