A steam turbine power generation facility and an operation method of such facility not only overcome the thermal elongation difference between a revolving body and a stationary body of a turbine so as to shorten start-up time but also suppress the efficiency of such facility from deterioration. The steam turbine power generation facility includes a boiler to generate steam; a high-pressure turbine into which the steam generated by the boiler flows; an intermediate-pressure turbine into which steam worked at the high-pressure turbine flows; and a low-pressure turbine into which steam worked at the intermediate-pressure turbine flows, in which the high-pressure turbine and the intermediate-pressure turbine are respectively provided with a heating section which is formed by communicating through the high-pressure turbine and the intermediate-pressure turbine, and further includes a pipe to make the steam worked at the high-pressure turbine flow into the heating section.
