Zusammenfassung:A gas turbine power plant is disclosed which uses gas turbine engine components in conjunction with an air reservoir and a motor-generator. The compressor unit has low pressure, intermediate pressure and high pressure compressors and control valves which allow operation of the low pressure compressor by a low power auxiliary motor during starting while the other compressors do not absorb significant power. The power plant can operate by the motor-generator to charge the reservoir, can operate on the air cell with a turbine during peak load, and can function as a conventional gas turbine installation when the air reservoir is exhausted.
