A system is described for allowing short term power augmentation of a gas turbine or a gas turbine combined cycle power plant. A reservoir of pressurized and/or liquefied gas is installed to store a transient supply of gas turbine working fluid. This supply of working fluid is available for near instantaneous admission to the gas turbine at the compressor discharge or combustion system to boost output, as may be desirable to assist in supporting electrical grid frequency during a transient disturbance (frequency reduction).

1. A gas turbine apparatus comprising:a gas turbine system including a compressor, a combustion system, and a gas turbine; and means for generating a transient plant power boost that can be selectively supported via injection of a first gas in gaseous form, comprising: a working fluid source, said working fluid source comprising at least one of a compressed gas storage vessel and a liquefied gas storage vessel, each said vessel containing and storing substantially solely said first gas, said vessel being operatively coupled via a working fluid flow control valve to a fluid flow path extending between said compressor and said gas turbine for selectively directly adding said first gas in gaseous form to fluid flowing through said fluid flow path at a point downstream of said compressor and upstream of said gas turbine.
