By improving a turbine efficiency, a power generation efficiency can be easily improved. The thermal power plant of the present invention comprises, for example: a boiler 1 that heats a feed water by utilizing a heat caused by combustion of a fossil fuel so as to generate a main steam A; reheaters 41 and 42 installed in the boiler 1 ; a turbine 2 ; and a generator 13 connected to the turbine 2 . The turbine 2 includes: a high pressure turbine into which the main steam A from the boiler 1 is introduced; an intermediate pressure turbine 9 into which the reheated steams E and F generated by the reheaters 41 and 42 are introduced, the intermediate pressure turbine 9 being uniaxially connected to the high pressure turbine 8 ; and a low pressure turbine 11 into which the reheated steams E and F discharged from the intermediate pressure turbine 9 is introduced, the low pressure turbine 11 being coupled with the high pressure turbine 8 and the intermediate pressure turbine 9 . The generator 7 has more than two poles, and is coupled with the high pressure turbine 8 , the intermediate pressure turbine 9 , and the low pressure turbine 11.
