To provide a solar thermal gas turbine power plant in which the thermal efficiency is improved by enabling power generation by a steam turbine even if the operation of a solar thermal gas turbine is stopped due to the reduction in the intensity of sunlight.
The solar thermal gas turbine power plant is provided with a solar thermal gas turbine GT which is provided with a compressor 1, a heat receiver 2, and a turbine 3; an electric generator 4 which is driven by the solar thermal gas turbine GT to generate electricity; and a steam power generation cycle 20A in which high temperature air discharged from the turbine 3 is introduced into a steam generator 21 and a steam turbine 22 which is driven by the steam generated by the steam generator 21 drives an electric generator 23 to generate electricity. A solar thermal steam generator 30 which generates steam by heating using heat collected by a light collector H is provided on the upstream of the steam turbine 22 in the steam power generation cycle 20A. The distribution ratio at which the sunlight collected by the light collector H is distributed to the heat receiver 2 and the solar thermal steam generator 30 is adjusted in accordance with the intensity of the sunlight.
