The present invention relates to a system and method for providing information on secondary batteries for power storage to an electric power consumer in order to determine whether or not a secondary battery should be installed. A communication terminal (Internet terminal) sends to a consumer information including inquiries on electric power used by the consumer, and/or inquiries on limitations of an area and a height of a site usable for installation of a secondary battery at the location of the electric power consumer. A processor calculates, using the information on used electric power and/or the information on the limitations of the area and the height accepted from the electric power consumer, a capacity and a maximum output of a secondary battery suitable for the consumer, calculates the amount of saved power fee settled by the installation of the secondary battery, and/or calculates a cost cut effect for the electric power consumer resulting from purchase or lease of the secondary battery based on the price of the secondary battery, the amount of saved power fee and so on. The communication terminal sends the information on the capacity and the maximum output of the secondary battery, the amount of saved power fee, and/or the cost cut effect to the consumer.
