The gas turbine plant is provided with a gas turbine (10), a heating device (60), a decomposition gas line (70), and a decomposition gas compressor (85). The heating device (60) heats ammonia and thermally decomposes the ammonia to convert the ammonia into decomposition gas (PG) including hydrogen gas and nitrogen gas. The decomposition gas line (70) sends the decomposition gas PG from the heating device (60) to the gas turbine (10). The decomposition gas compressor (85) increases the pressure of the decomposition gas (PG) to a pressure equal to or higher than a feed pressure at which the decomposition gas (PG) is allowed to be fed to the gas turbine (10).
