Beschreibung
Zusammenfassung:	Provided is technology to efficiently store and use, in a plurality of different temperature ranges, excess energy generated at a power generation plant. A heat storage device 140 that has a plurality of heat storage units to recover and accumulate heat from a fluid passing through a channel provided therein is characterized by comprising a first heat storage unit that has temperature characteristics in a first temperature range, a second heat storage unit that has temperature characteristics in a second temperature range, which is a lower temperature range than the first temperature range, a first channel 241 that causes inflowing fluid to pass through the first heat storage unit and the second heat storage unit in order, a second channel 242 that causes the inflowing fluid to bypass the first heat storage unit and pass through the second heat storage unit, a first on-off valve 251 that is provided on the first channel 241, and a second on-off valve 252 that is provided on the second channel 242, wherein the
