1. An electric power management system for managing an electric power system, the electric power management system comprising:

  • a plurality of first consumers each comprising a consumer energy management system for controlling an amount of electric power generated by a photovoltaic system, and a plurality of second consumers each comprising a consumer energy management system for controlling a controllable load,wherein the controllable load is a device which can store energy,wherein the electric power management system comprises a server apparatus that transmits data to the consumer energy management systems of the first consumers and the consumer energy management systems of the second consumers, and that receives data from the consumer energy management systems of the first consumers and the consumer energy management systems of the second consumers via a network, andwherein the server apparatus combines two or more consumers from among the plurality of first consumers and the plurality of second consumers so that the amount of electric power needed by a second consumer will be equal to or greater than a surplus electricity generated in a first consumer in a predetermined time slot on a predetermined date on which the surplus electricity of the photovoltaic system is expected to be generated, and makes the controllable load consume the surplus electricity generated in the first consumer by controlling the consumer energy management system of the second consumer with respect to each combination of the first consumer and the second consumer, and makes the controllable load store the surplus electricity generated in the first consumer by controlling the consumer energy management system of the second consumer at different timing with respect to each combination of the first consumer and the second consumer.
