An energy saving support system according to an embodiment is configured to provide a consumer, who has an electric load to which electric energy is supplied from an electric power supply system within a house, with energy consumption-related information through a photo frame or the like. The information providing apparatus is configured to acquire an acceptability level, which stepwise indicates a degree of interest of the consumer in the energy consumption-related information, and to determine the energy consumption-related information to be newly provided to the consumer based on the acceptability level.

Energy saving support system

A power supply management system according to an embodiment of the present invention includes a fee setting unit configured to set power fee unit prices (first power fee unit price and second power fee unit price) for each time slot, and a notification unit configured to notify a consumer of information on the set power fee unit prices. The first power fee unit price is a power unit price for a household electrical load, and the second power fee unit price is a power unit price in a case of using a charge/discharge device to charge a vehicle-mounted storage battery. The fee setting unit is configured to set, by predicting a load factor of a transformer, a discount rate of the second power fee unit price to become higher (second power fee unit price to become lower) as the predicted load factor becomes lower. The second power fee unit price is determined on the basis of the first power fee unit price and the discount rate.
