A compressed air production facility having an air compressor and an electric motor, a gas turbine power generation facility having a gas turbine and a generator, and storing air compressed by the air compressor and converting the compressed air into a gas turbine combustor. A power storage type gas turbine power generation facility comprising: a compressed air storage tank for supplying; a steam turbine for auxiliary driving the air compressor; a steam generator for continuously generating high-pressure steam; and steam generation. A steam line for supplying high-pressure steam from the device to the steam turbine and the gas turbine combustor, and when driving the compressor at night, supplies steam to the steam turbine to reduce the driving power of the air compressor; During daytime gas turbine power generation, when steam is supplied to the gas turbine or gas turbine combustor to increase the output, and when the gas turbine and air compressor are operated simultaneously, The excess pressure steam supplied to the steam turbine to reduce the driving power of the air compressor, power storage gas turbine power generation facility, characterized in that.
