Abstract

An energy management device includes a measurement manager and a communicator. The measurement manager manages energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in a customer. The communicator communicates the energy information of each of the energy types to another device over a network.

Claims

1. An energy management system comprising:

an energy management device disposed in a supply side, an owner of the energy management device being a first owner;

a first energy management device disposed in a customer side, an owner of the first energy management device being the first owner; and

a second energy management device disposed in the customer side, an owner of the second energy management device being a second owner, the first owner being different from the second owner,

wherein the energy management device comprises;

a configuration manager to determine whether to permit communication connection from the energy management device to the second energy management device based on information defining whether or not an energy management server is able to connect to the second energy management device; and

,

a measurement manager to collect, via a network, from the second energy management device if communication connection to the second energy management device is permitted, or from the first energy management device if communication connection to the second energy management device is not permitted, energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in the customer side.

2. The energy management system according to claim 1, further comprising:

a control manager to control the second energy management device if connection to the second energy management device is permitted, or control the first energy management device if connection to the second energy management device is not permitted to manage energy of each of the energy types on the customer side.

3. An energy management device disposed in a supply side, a first energy management device and a second energy management device being disposed in a customer side, the energy management device comprising:

a configuration manager to determine whether to permit communication connection from the energy management device to the second energy management device based on information defining whether or not an energy management server is able to connect to the second energy management device, an owner of the energy management device being a first owner, an owner of the first energy management device being the first owner and an owner of the second energy management device being a second owner, the first owner being different from the second owner; and

a measurement manager to collect, via a network, from the second energy management device if communication connection to the second energy management device is permitted, or from the first energy management device if communication connection to the second energy management device is not permitted, energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in the customer side.

4. The energy management device according to claim 3, wherein the first owner is a public service company, and the second owner is a customer, or an owner or a developer of a facility.

5. The energy management device according to claim 3, wherein the plurality of energy types include:

at least categories of electric power and energies other than electric power, or

at least categories of electric power consumption, electric power storage, and electric power generation, or

at least categories of electric power, water, and gas.

6. The energy management device according to claim 3, further comprising:

a control manager to control the second energy management device if connection to the second energy management device is permitted, or control the first energy management device if connection to the second energy management device is not permitted to manage energy of each of the energy types on the customer side.

7. An energy management method performed by an energy management device disposed in a supply side, a first energy management device and a second energy management device being disposed in a customer side, the energy management method comprising:

determining whether to permit communication connection from the energy management device to the second energy management device based on information defining whether or not an energy management server is able to connect to the second energy management device, an owner of the energy management device being a first owner, an owner of the first energy management device being the first owner, an owner of the second energy management device being a second owner, the first owner being different from the second owner; and

collecting, via a network, from the second energy management device if communication connection to the second energy management device is permitted, or from the first energy management device if communication connection to the second energy management device is not permitted, energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in the customer side.

8. The energy management method according to claim 7, further comprising:

controlling the second energy management device if connection to the second energy management device is permitted, or controlling the first energy management device if connection to the second energy management device is not permitted to manage energy of each of the energy types on the customer side.

9. A non-transitory computer readable medium having a computer program stored therein which causes a computer arranged in an energy management device disposed in a supply side to perform processes, a first energy management device and a second energy management device being disposed in a customer side, the processes comprising:

determining whether to permit communication connection from the energy management device to the second energy management device based on information defining whether or not an energy management server is able to connect to the second energy management device, an owner of the energy management device being a first owner, an owner of the first energy management device being the first owner, an owner of the second energy management device being a second owner, the first owner being different from the second owner; and

collecting, via a network, from the second energy management device if communication connection to the second energy management device is permitted, or from the first energy management device if communication connection to the second energy management device is not permitted, energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in the customer side.

10. The medium according to claim 9, further causing the computer to perform processes comprising:

controlling the second energy management device if connection to the second energy management device is permitted, or controlling the first energy management device if connection to the second energy management device is not permitted to manage energy of each of the energy types on the customer side.
