Abstract: Disclosed is a monitoring apparatus (10) including a user management unit (11) that acquires, in association with each of plural users, a residual power level of a storage battery used by the user, a detection unit (12) that detects a predetermined event, and a setting unit (13) that sets, when the predetermined event is detected, the degree of urgency of need for a predetermined measure for each user based on the residual power level of the storage battery.

Abstract: Provided is an electric power supply and demand control apparatus (10) including a remaining battery level acquisition unit (11) and a setting unit (12), in order to solve the aforementioned problems. The remaining battery level acquisition unit (11) acquires remaining battery level information indicating a remaining battery level of a storage battery of a consumer. The setting unit (12) sets an expectation value of a reduction in power purchase from a system performed by the consumer, on the basis of the remaining battery level information acquired by the remaining battery level acquisition unit (11). For example, a high expectation value is set for a consumer whose storage battery has a large remaining battery level.

Abstract: Provided is a management device (10) including a schedule acquisition unit (11) that acquires a power generation schedule in a first power generation unit which shows output power according to time, a change information acquisition unit (12) that acquires change information indicating change details of necessary output power in the first power generation unit, a storage battery information acquisition unit (13) that acquires storage battery information indicating free capacities of a plurality of storage batteries in a case where the change information acquisition unit (12) acquires the change information, and a correction unit (14) that corrects the power generation schedule on the basis of the change information and the storage battery information.

Abstract: Disclosed is a monitoring apparatus (10) including a user management unit (11) that acquires, in association with each of plural users, a residual power level of a storage battery used by the user, a detection unit (12) that detects a predetermined event, and a setting unit (13) that sets, when the predetermined event is detected, the degree of urgency of need for a predetermined measure for each user based on the residual power level of the storage battery.

Abstract: There is provided a communication allowability range output system capable of specifying a range in which communication is not available in a network. A communication allowability range output device 72 outputs information indicating a communication allowability range of a network formed by a plurality of wireless communication devices 71 based on position information of the wireless communication devices 71 and information on whether the wireless communication devices 71 are operating.

Abstract: Provided is a rewards information determining device that can determine rewards information that indicates rewards to be provided to a power consumer according to the degree of power saving of the power consumer not to cause unfairness to the power consumer. Information acquiring means 81 acquires information of first consumed power consumed by the power consumer. Rewards information determining means 82 determines the rewards information of the power consumer based on information of standard consumed power of a group to which the power consumer belongs, and the information of first consumed power.
