FIELD: gas turbo-expander plants with recuperation of heat and realization of excessive pressure of natural gas in turbo-expanders. SUBSTANCE: high-pressure natural gas enters turbo-expander 3 via main 1 through adjustable nozzle apparatus 4 where pressure is reduced to required level. Power of turbo-expander 3 is summed with power of turbine 9 of aircraft engine 5 and is transmitted to electric generator 18. Temperature of natural gas at turbo-expander outlet is maintained above 273 K by means of exhaust heat of aircraft engine 5 and is regulated by means of device 15. Power of aircraft engine 5 changes in wide range, zero magnitude inclusive, thus providing for high ecological indices. EFFECT: enhanced efficiency, ecological safety. 1 dwg
