Abstract: An equipment management system comprises a gateway apparatus having an interface configured to receive an operation command for operating an equipment, a first database configured to store first information allowed access from the gateway apparatus, a second database configured to store second information prohibited access from the gateway apparatus, and a controller configured to allow access to the first database from the gateway apparatus and prohibit access to the second database from the gateway apparatus. The second information includes equipment information collected from a control apparatus controlling the equipment.

Abstract: An information processing apparatus that outputs information for identifying a combination of batteries including a solar battery, a fuel cell, and a storage battery includes a storage unit and a control unit. The storage unit stores effects of each of solar batteries, fuel cells, and storage batteries constituting the combinations of batteries from an environmental perspective, a safety perspective, and an economical perspective. The control unit performs control such that information for identifying, among the combinations of batteries, a combination determined on a basis of the effects of each of the solar batteries, the fuel cells, and the storage batteries constituting the combinations of batteries from the environmental perspective, the safety perspective, and the economical perspective is output.

Abstract: Provided is a cogeneration system that includes a plurality of fuel cell devices capable of supplying heat and power to a heat load and a power load and a control device connected to the fuel cell devices. The control device determines an operation mode on the basis of at least one of a heat demand value and a power demand value. The control device controls a power generation efficiency and a heat recovery efficiency by controlling the fuel cell devices on the basis of the operation mode determined.

Abstract: In a management system, a management apparatus includes a detector configured to detect an operating status of a piece of electric equipment installed in a house, and a transmitter configured to transmit, to a first management server, operation information of the operating status detected by the detector. The first management server includes a receiver configured to receive the operation information from the management apparatus, and a calculator configured to calculate a responsivity index based on operation information of a piece of specific electric equipment among a plurality of the pieces of electric equipment, the responsivity index indicating a possibility that a user of the piece of electric equipment is capable of responding to an external request.

Abstract: An information processing apparatus includes a controller for calculating an economic benefit resulting from energy saving attributed to a power generation apparatus and/or a power storage apparatus, based on first information regarding electric power supplied from the power generation apparatus and/or the power storage apparatus at a predetermined base and electric power supplied to the predetermined base from a commercial power grid, second information regarding electric power stored in the power storage apparatus, third information regarding electric power consumed at the predetermined base, information regarding cost corresponding to the electric power, and information regarding cost of the power generation apparatus and/or the power storage apparatus, and also calculate a period to be taken by the economic benefit to recover the cost of the power generation apparatus and/or the power storage apparatus.

Abstract: Power management apparatuses, power management systems, and power management methods for controlling power of a storage cell so as to allow appropriate compliance with requests from both the power supply side and the consumer side. A power management apparatus is provided in a consumer facility and includes a controller that manages the amount of stored electricity. The controller divides the amount of stored electricity at least into a first domain and a second domain and manages the domains, where the first domain is a domain in which to perform long-term control and the second domain is a domain in which to perform short-term control during power management in the consumer facility.
