POWER USAGE CALCULATION SYSTEM
First Claim
1. A power usage calculation system in which a data management system, which is connected to a plurality of electric power meters adding up power usage of electric apparatuses, and an energy management system are interconnected through a network, the power usage calculation system comprising:
- a first calculator that calculates a plurality of pieces of first partial information by using the power usage added up by the electric power meters,wherein the data management system includes a plurality of storage servers, the each of the storage servers storing each corresponding pieces of the first partial informationwherein each of the storage servers includes;
a second calculator that calculates second partial information by using a plurality of pieces of the first partial information of the power usage added up by the plurality of the electric power meters; and
a transmission unit that transmits the second partial information to the energy management system,wherein the energy management system includes;
a first reception unit that receives the second partial information transmitted from the plurality of storage servers; and
a third calculator that calculates a total amount of the power usage added up by the plurality of the electric power meters by using a plurality of pieces of the second partial information, andwherein the first partial information is information that cannot specify privacy information.

Abstract
According to an embodiment, in a power usage calculation system, a data management system connected to electric power meters adding up power usage of electric apparatuses and an energy management system are interconnected through a network. Plural pieces of the first partial information are calculated by using the power usage added up by the electric power meters. The plural pieces of the first partial information are stored in storage servers. Each storage server calculates second partial information by using a plurality of pieces of the first partial information of the power usage added up by the electric power meters and transmits the calculated second partial information to the energy management system. The energy management system receives the second partial information respectively transmitted from the storage servers and calculates a total amount of the power usage added up by the electric power meters by using the received second partial information.
