PROBLEM TO BE SOLVED: To provide a power generation method by which solar heat is efficiently utilized and a heat source other than the solar heat such as underground heat is utilized when there is not enough solar heat, thereby achieving stable power supply.SOLUTION: In the power generation method, a medium liquid is heated by exchanging heat with hot water heated by a heat source other than solar heat, the heated medium liquid is heated by the solar heat in a steam generation facility 10 and a solar heat furnace 20 to generate steam, the generated steam is transferred to a steam turbine and the steam turbine is rotated to generate power. In the power generation method, a concave reflection mirror is vertically arranged around the steam generation facility 10 and the solar heat furnace 20 so as to reflect the solar light toward the steam generation facility 10 and the solar heat furnace 20, and the solar heat is converged on the steam generation facility 10 and the solar heat furnace 20. When the solar heat cannot be used in heating to generate the steam, the heat source other than the solar heat is used in the heating to generate the steam. By this, power can be stably supplied even during the night, in the rainy weather, in the cloudy weather or the like. |
