Claim:
1. A storage battery control apparatus which controls charge and discharge of the storage battery to adjust power supply and demand of a grid in a supply and demand control period, the storage battery control apparatus comprising: a first obtainer that obtains a remaining state of charge (SOC) which is an SOC of the storage battery at a start of the supply and demand control period; an offset power value determiner that determines an offset power value which is a power value indicating charge or discharge and is a reference of the charge and discharge of the storage battery in the supply and demand control period, the offset power value being determined using a difference between the remaining SOC and a target SOC, and the target SOC being (i) a target value of the SOC of the storage battery at an end of the supply and demand control period and (ii) a fixed value less than 100% of a capacity of the storage battery; a second obtainer that obtains an adjustment instruction value which is an instruction value of the charge and discharge of the storage battery and indicates a change amount of a power value from a predetermined reference power value; and a charge and discharge controller that performs control of discharging power from the storage battery to the grid or charging power from the grid to the storage battery, the power having a magnitude of a first power value that is a power value obtained by adding the offset power value to an adjustment instruction power value that is a power value indicated by the adjustment instruction value.
