Energy control device and energy control system equipped with the energy control device

An energy control system, comprising:

• an energy control device adapted to adjust an amount of energy consumed by mechanical equipment placed at a property;
• a communication device having a receiving unit configured to receive a demand adjustment request from an energy supply company;
• and
• a storage device configured to store information related to the amount of energy consumed by the mechanical equipment,
• the communication device being configured to forward the demand adjustment request to the energy control device, and
• the energy control device including
• a first control unit configured to execute a first adjustment control during a prescribed adjustment period, the first adjustment control adjusting an amount of energy consumed by the mechanical equipment, the amount of energy consumed by the mechanical equipment being adjusted in accordance with a first upper limit amount of energy consumption which achieves the demand adjustment request from the energy supply company in the first adjustment control, and
• a second control unit configured to execute a second adjustment control separate from the first adjustment control during a non-adjustment period after the adjustment period, the amount of energy consumed by the mechanical equipment being adjusted not to exceed a second upper limit amount of energy consumption, which is higher than the first upper limit amount of energy consumption, in second adjustment control,
• the second upper limit amount of energy consumption being determined based on an amount of energy consumed by the mechanical equipment before the adjustment period, and the second upper limit amount of energy consumption being determined based on the information stored by the storage device.
