Demand response system, terminal apparatus, server, controlling method, and recording medium

A server which is capable of communicating via a network with a terminal apparatus capable of controlling an energy consumption device, the server comprising:

• a receiving unit configured to receive a second identifier from the terminal apparatus connected to the energy consumption device, the second identifier identifying a contract unique to each user, for controlling the energy consumption device;
• a control unit configured to generate a control schedule based on the contract identified by the second identifier, the control schedule being for the energy consumption device;
• and
• a transmission unit configured to transmit, to the terminal apparatus, the control schedule generated by the control unit.

A terminal apparatus which is capable of controlling an energy consumption device, the terminal apparatus comprising:

• an input unit configured to accept a first identifier and a second identifier, the first identifier identifying a server which generates information for performing control on the energy consumption device, the second identifier identifying a contract unique to user, for the control;
• a transmission unit configured to transmit the second identifier to the server identified by the first identifier;
• a receiving unit configured to receive, from the server, a control schedule as a response to the transmitted second identifier, the control schedule being generated based on the contract by the server and being for the energy consumption device;
• and
• a control unit configured to control the energy consumption device to reduce energy consumption by the energy consumption device, based on the control schedule received by the receiving unit.

A controlling method in a terminal apparatus which is capable of controlling an energy consumption device, the controlling method comprising:

• accepting a first identifier and a second identifier, the first identifier identifying a server which generates information for performing control of the energy consumption device, the second identifier identifying a contract unique to each user, for the control;
• transmitting the second identifier to the server identified by the first identifier;
• receiving, from the server, a control schedule as a response to the transmitted second identifier, the control schedule being generated based on the contract by the server and being for the energy consumption device;
• and
• controlling the energy consumption device to reduce energy consumption by the energy consumption device, based on the control schedule received in the receiving.
