2. Description of the Related Art Since power consumption is significantly different between day and night,
There is a pumped storage power plant as a power storage device that stores excess power at night and discharges (generates power) during peak load during the day. At the pumped storage power plant, surplus electricity at night is used to pump water from the lower dam to the upper dam, and power is generated by the turbine generator during the day. Pumped storage power plants are built by building dams in the mountains. For this reason, there are restrictions on the location and the construction period is long, so it is not quick to respond to the increasing electricity consumption gap between day and night. Therefore, the peak power demand during the daytime depends on the operation of the oil-fired power plant or the like, but the oil-fired power plant emits carbon dioxide which causes global warming.
