Abstract: Provided is a supply-and-demand management apparatus including: a result management unit that manages a power supply result indicating a result of power supplied among a plurality of customers of a community; and a deriving unit that derives, based on power supply results from a first customer to other customers from among the plurality of customers, an incentive to supply power from the first customer to a second customer from among the other customers.

Abstract: An energy management device comprises a first supply/demand information acquisition unit, a second supply/demand information acquisition unit, and a supply/demand management unit configured to determine, based on the first supply/demand information and the second supply/demand information, at least one of (i) an upper limit value of a power amount that the hydrogen generation system can receive from a power grid during a certain period, (ii) a target value of an amount of hydrogen that the hydrogen generation system generates during the certain period, (iii) an upper limit value of a power amount that each of the one or plurality of tri-generation systems can transmit to the power grid during the certain period, and (iv) a target value of a power amount that each of the one or plurality of tri-generation systems generates during the certain period.

Abstract: Included are: a performance information obtaining unit that obtains, for each of a plurality of first power customers that configure a first community, information about a power interchange performance between the first power customer and the first community; a contribution degree determination unit that determines a contribution degree of at least one of the plurality of first power customers to a surplus power amount of the first community in a certain time period, based on information about the performance obtained by the performance information obtaining unit.

Abstract: A sensor container includes a container body having an opening portion, a lid that covers the opening portion of the container body, and a plurality of sensors for measuring biological information that are housed in the container body. The container body or the lid has a mark that includes information indicating the usable period of the sensors starting from a point in time when the lid is released from the container body. The mark is covered with a removable seal.
