Abstract: It is provided a management system for managing renewable energy verification comprising: an arithmetic device configured to execute predetermined processing; a storage device coupled to the arithmetic device, an input unit configured to receive a supply ratio of renewable energy in a manufacturing process, and input quantities of a renewable energy-derived raw material and a renewable energy-derived part out of raw materials and parts input to the manufacturing process; and an RE verification granting module configured to calculate, with use of the received input about the supply ratio of renewable energy and about the input quantities of the renewable energy-derived raw material and the renewable energy-derived part, at least one of the number of pieces to be granted renewable energy verification out of pieces of a manufactured item manufactured by the manufacturing process, or a ratio of pieces of the manufactured item that are to be granted renewable energy verification.

Abstract: To minimize the amount of calculation for changing an operation schedule even when there is an increase in the number of sites. A management computer calculates a first total schedule value, which is the total of the schedule values for each of the sites within a first time frame. If the first total schedule value exceeds a first target value set in advance, the management computer: calculates a first excess amount of the first total schedule value in relation to the first target value; selects, as a first site, a site subjected to a change in a demand schedule from a group of candidate sites satisfying a candidate criterion set in advance from among a plurality of the sites, the selection being performed on the basis of information on the facility characteristics for each of the sites; changes a first demand schedule of the first site in the first time frame; and transmits the changed first demand schedule to a control device of the first site.

Abstract: An information management system collects and manages information on a charging stand that allows a user to effectively utilize the time during charging. The information management system acquires, from a probe information management device that stores location information of a vehicle and battery residual capacity information of a battery provided in the vehicle, the location information of the vehicle and the battery residual capacity of the vehicle; and acquires, from a user operation terminal operated by a user who gets on the vehicle, destination information indicating a location of a destination of the vehicle input by the user and information on what the user wants to do during charging of the vehicle. A storage unit stores the location information of the vehicle and the battery residual capacity information in association with the destination information of the vehicle and the information on what the user wants to do during the charging.
