FIELD: energy generation. SUBSTANCE: process increasing energy produced by system of gas turbine includes compression of ambient air by main compressor and preliminary compression of air during hot humid weather above flow from main compressor to pressure value not higher than 115% of pressure of ambient air. Prior to feed of preliminarily compressed air to main compressor it is cooled. Air compressed in main compressor is heated in combustion chamber with formation of hot gases expanding further in gas turbine that drives main compressor and load. Formed hot exit gases are used to produce steam employed for accompanying generation or for driving of steam turbine. Such implementation of process leads to increased energy production during hot humid weather. EFFECT: increased energy production. 10 cl, 5 dwg
