[0039] As shown in Figure 6(b), the setting change unit 508 instructs the target to change its settings. The display control unit 506 displays an input field for entering the setting value after the setting change, and the setting change unit 508 can instruct the target to change its settings based on the setting value entered in the input field. The display control unit 506 may display multiple selectable settings as shown in Figure 6(b). The setting change unit 508 can instruct the selected multiple settings to change settings based on predetermined setting values ​​or setting values ​​entered in the input fields. As a result, when the equipment operator terminal 500 receives a request for cooperation in saving electricity, it can select multiple settings, set setting values ​​for the selected multiple settings, and instruct the setting change. Consequently, the equipment operator can respond to the request for cooperation in saving electricity by operating the equipment operator terminal 500. Furthermore, when a setting change is made, the setting information acquisition unit 510 may acquire the setting value information after the setting change for the setting target operated by the equipment operator indicated in the equipment operator information, based on the setting change information. The reporting unit 512 reports the acquired setting value information after the setting change to the facility manager predetermined for each equipment operator indicated in the equipment operator information. As a result, the equipment operator terminal 500 can notify the facility manager of the details of the setting change when the equipment operator changes the settings of the equipment. In this way, the facility manager can check the status of the equipment operator's response to the request for cooperation in saving electricity.

The first notification destination setting unit 202 of the area notification server device 200 sets facility notification destination information for each energy supply destination facility 700 (step S100). The second notification destination setting unit 302 of the facility server device 300 sets facility notification destination information for multiple facility operators (step S102).

[0041] The area energy management device 100 predicts the balance between the energy supplied from the energy supply facility 600 to the energy recipient facility 700 and the energy demanded by the energy recipient facility 700 (step S104). If the energy demand does not exceed the energy supply (step S106: NO), the area energy management device 100 returns to step S104. For example, if the energy demand exceeds the energy supply, the area energy management device 100 determines whether to request a power saving (step S106: YES) and sends a power saving cooperation request to the EMS administrator terminal 210.

[0042] The EMS administrator terminal 210, acting as the first terminal, obtains facility notification destination information from the area notification server device 200 (step S108), and the first notification control unit 214, based on the obtained facility notification destination information, causes the facility cooperation notification to be sent as the first notification to at least one of the multiple energy supply destination facilities 700 (step S110), thereby sending the facility cooperation notification to the area notification server device 200. Upon receiving the facility cooperation notification, the area notification server device 200 sends the facility cooperation notification to the facility administrator terminal 400.

[0043] The first selection unit 204 may select a target facility based on area energy information indicating energy information for the entire target area, and the first notification control unit 214 may send the first notification to the notification destination of the target facility selected by the first selection unit 204.

[0044] The facility administrator terminal 400, acting as a second terminal, notifies the facility administrator via the first notification unit 402 when it receives a facility cooperation notification as a first notification (step S112). The facility administrator terminal 400 acquires equipment operator information and equipment notification destination information (step S114). Based on the equipment notification destination information, the second notification control unit 406 causes the facility server device 300 to send a facility cooperation notification as a second notification to at least one notification destination of multiple equipment operators within the energy supply destination facility 700.

[0045] Upon receiving the facility cooperation notification, the facility server device 300 sends the facility cooperation notification to the facility operator terminal 500 (step S116). The facility operator terminal 500 then notifies the facility operator of the power saving cooperation based on the facility cooperation notification.

[0046] The second selection unit 304 may select target equipment based on facility energy information calculated by the energy supply destination facility 700. The facility server device 300 transmits information indicating the selected target equipment to the facility administrator terminal 400, and the second notification control unit 406 can cause the facility server device 300 to send a facility cooperation notification as a second notification to the notification destination of the target equipment selected by the second selection unit 304.

[0047] Figure 8 shows another example of the operation flow of the energy management system 1 in the embodiment. The first notification destination setting unit 202 of the area notification server device 200 sets facility notification destination information for each energy supply destination facility 700 (step S100). The second notification destination setting unit 302 of the facility server device 300 sets facility notification destination information for multiple facility operators (step S102). Furthermore, the facility server device 300 sets setting change information (step S200).

[0048] The area energy management device 100 predicts the balance between the energy supplied from the energy supply facility 600 to the energy recipient facility 700 and the energy demanded by the energy recipient facility 700 (step S104). If the energy demand does not exceed the energy supply (step S104: NO), the area energy management device 100 returns to step S102. For example, if the energy demand exceeds the energy supply, the area energy management device 100 determines whether to request a power saving (step S104: YES) and sends the power saving cooperation request to the EMS administrator terminal 210.

[0049] The EMS administrator terminal 210, acting as the first terminal, obtains facility notification destination information from the area notification server device 200 (step S108), and the first notification control unit 214, based on the obtained facility notification destination information, causes the facility cooperation notification to be sent as the first notification to at least one of the multiple energy supply destination facilities 700 (step S110), thereby sending the facility cooperation notification to the area notification server device 200. Upon receiving the facility cooperation notification, the area notification server device 200 sends the facility cooperation notification to the facility administrator terminal 400.

[0050] The facility administrator terminal 400, acting as a second terminal, notifies the facility administrator via the first notification unit 402 when it receives a facility cooperation notification as a first notification (step S112). The facility administrator terminal 400 acquires equipment operator information and equipment notification destination information (step S114). Based on the equipment notification destination information, the second notification control unit 406 causes the facility server device 300 to send a facility cooperation notification as a second notification to at least one notification destination of multiple equipment operators within the energy supply destination facility 700.

[0051] Upon receiving the facility cooperation notification, the facility server device 300 sends the facility cooperation notification to the facility operator terminal 500 (step S116). The facility operator terminal 500 then notifies the facility operator of the power saving cooperation based on the facility cooperation notification. Furthermore, the facility operator terminal 500 obtains facility operator information and information to be configured (step S202). The facility operator terminal 500 then displays the equipment to be configured (step S204). The facility operator terminal 500 also displays information according to the type of configuration change (step S206).

[0052] As described above, according to the energy management system 1 of this embodiment, the area notification server device 200 sets facility notification destination information for each energy supply destination facility 700, the facility server device 300 for each energy supply destination facility 700 sets equipment notification destination information for multiple equipment operators, the EMS administrator terminal 210 sends a facility cooperation notification (first notification) to at least one notification destination of the multiple energy supply destination facilities 700 based on the facility notification destination information, the facility administrator terminal 400 notifies the facility administrator when it receives the first notification, and sends an equipment cooperation notification (second notification) to at least one notification destination of multiple equipment operators within the energy supply destination facility 700 based on the equipment notification destination information, and the equipment operator terminal 500 notifies the equipment operator when it receives the second notification. As a result, the energy management system 1 realizes a hierarchical structure of notifications, and for example, when it becomes necessary to conserve energy in a regional EMS, various players participating in the regional EMS can jointly use energy and operate the regional EMS smoothly.
