Zusammenfassung:	A compressed air energy storage power generation device 2 includes a compressor 6, a pressure accumulator tank 8, and an expander 10. The compressor 6 compresses air by being driven with renewable energy. The pressure accumulator tank 8 stores the air compressed by the compressor 6. The expander 10 is driven by the compressed air. A power generator 36 is mechanically connected to the expander 10 and generates electric power, which is to be supplied to a demander. The compressed air energy storage power generation device 2 includes: first heat exchanges 16 for recovering compression heat; temperature sensors 29a to 29c that measure the temperatures of the heat media having the temperature increased by the first heat exchangers 16; high-temperature heat medium tanks 19 and 20, each of which individually stores the heat medium depending on the temperature thereof; second heat exchangers 22 for heating compressed air; a low-temperature heat medium tank 21 that stores the heat medium having the temperature decreased in the second heat exchanger 22; and a control unit 40 that switches high-temperature heat storage switching valves 31a and 31b to thereby supply the heat medium from the first heat exchangers 16 to either of the high-temperature heat medium tanks 19 and 20. Thus, the compressed air energy storage power generation device 2 can prevent the high-temperature heat medium from mixing with the low-temperature heat medium.
