  By the way, conventionally, the same customer can conclude a plurality of electric contracts with an electric power company. Examples of the same customer having multiple electric contracts with an electric power company are cases where the same customer has multiple electric contracts under the contractor's name, or the same customer pays common electric charges for multiple electric contracts. You may be a person. A case where the same customer has a plurality of electric contracts with an electric power company corresponds to a case where the customer is self-employed and the home and the store are separated. The case where the same customer is an electricity payer for a plurality of electricity contracts corresponds to a case where a customer's child lives in an apartment away from the customer's own home.

  Since such customers use a relatively large amount of electricity, if such customers become aware of power saving, for example, it is possible to reduce power consumption during peak power consumption. Become. However, there are currently few services that can raise the awareness of power saving for the customers as described above.

  In recent years, a power network that automatically adjusts power supply and demand has been constructed using an electric meter called a smart meter. The smart meter has a communication function. By introducing the smart meter, two-way communication between the electric power company and the electric meter and between the electric meter and the home computer is possible, and the smart meter is automatically used by the electric power company. Data such as the amount of power is transmitted. This eliminates the need for a meter reader to visit a home where a smart meter is installed. Moreover, since the power usage is transmitted from the smart meter to the power company every unit time (for example, 30 minutes), the power company can grasp the customer's power usage status in more detail. As a result, it is possible to grasp the amount of electric power used for each predetermined time zone (for example, every hour), so it is possible to propose to the customer an electricity rate menu that sets a unit price for each time zone. .

  As described above, in recent years, an environment has been set in which an electric power company can propose a new electricity price menu to customers. Therefore, an electricity bill menu creation device capable of proposing an electricity bill menu that has merits for customers who have a plurality of electricity contracts with an electric power company or who are payers of a plurality of electricity contracts The appearance of is desired.

  The present invention makes it possible to propose an advantageous electricity bill menu for customers who have a plurality of electricity contracts with an electric power company or who are payers of a plurality of electricity contracts. An object is to provide a fee menu creation device.

A power consumption acquisition unit that acquires power consumption, and a plurality of uses corresponding to the plurality of contract identification information acquired by the power consumption acquisition unit. A total used power amount calculation unit for obtaining a total used power amount obtained by adding the power amounts for each predetermined time zone, and a unit time zone in which the total used power amount calculated by the total used power amount calculation unit is maximized. Including the electricity charge for a predetermined time period including the price, and the electricity charge for the time period of the electric energy used for each unit time period so that the electricity charge for at least a part of the time period other than the predetermined time period is discounted. An electricity rate menu creation unit comprising: an electricity rate menu creation unit that creates an electricity rate menu that serves as a basis for an electricity rate for one day set to 1).

  According to (1), the amount of power used by a plurality of electric contracts of the same contractor or the same payer of electric charges is added up every predetermined time period. An electricity rate menu that sets the unit price for the amount of power used so that the electricity rate during the peak time of the combined value is higher and at least a portion of the electricity rate during other times is lower. To a customer who is the same contractor or the same payer of a plurality of electric contracts. As a result, the customer becomes aware of the time period in which the total value of power consumption reaches the maximum peak, and strives to reduce the power consumption in the time period when the maximum peak is reached. By supplementing in the time zone, even if the power consumption is the same, the electricity bill can be kept low. Moreover, for the electric power company, the amount of power used in the time zone where the maximum peak is reached can be reduced. In this way, it is possible to propose an electricity price menu that has advantages for both customers and power companies.

  (2) In (1), the electricity price menu creation unit sets a target power consumption amount for a predetermined time period based on an average value of the electricity charges for a predetermined time period, and the actual electric charge is An electricity bill menu creating apparatus characterized in that the unit price applied to the amount of power used in excess of the target power consumption in the time period is set at a high price.

  According to (2), when the customer tries to prevent the power consumption in the predetermined time period from exceeding the target power consumption, the power consumption in the maximum peak time period approaches the target power consumption. Thus, the amount of power used in the time zone where the maximum peak is reached is leveled. Thereby, on the electric company side, it becomes possible to perform stable power supply at the peak time.

  (3) In (1) and (2), a power usage pattern estimation unit that estimates a power usage pattern by the same customer based on information on past power consumption acquired by the power usage amount acquisition unit, and The power usage pattern estimated by the power usage pattern estimation unit is compared with the power usage amount sequentially transmitted from the smart meter to determine whether or not the current power usage amount is abnormal. And an additional service providing unit that, when determined, transmits information to that effect to the customer's terminal.

  According to (3), for example, when two electric contracts are for home use and for business use, for example, when the amount of electric use for home use is small and the amount of electric use for business use is large, or vice versa, It can be estimated that the customer is moving between the home and the store during that time. Therefore, if the customer uses excessive electricity while moving, the customer is informed of the possibility of leakage or unauthorized use at either the home or the store, or the electricity is not used much. If not, it will be possible to provide information to the customer that there is a planned power outage in the area between the two bases.

  According to the present invention, it is possible to propose an advantageous electricity bill menu for customers who have a plurality of electricity contracts with an electric power company or a customer who is a payer of a plurality of electricity contracts. It becomes possible to provide an electricity bill menu preparation apparatus.

[Specific example of electricity price menu]
Next, a specific example of the electricity price menu created by the proposed electricity price menu creation unit 30 will be described. Here, the customer is self-employed and has an electric contract with his / her own home and a store under his / her own name, and the two electric contracts are the same contractor and the same Shall be the payer of electricity charges. Further, the description will be made assuming that smart meters are installed in the home and the store, respectively.

  FIG. 3 is a diagram showing a transition of power consumption for a predetermined day, and FIG. 4 shows data of power consumption used at a home and a store for a predetermined day stored in the usage record database 26. FIG. That is, FIG. 3 is a graph of the data shown in FIG.

  3 and 4 include the total value of the power consumption used every hour at the home and the store calculated by the total power consumption calculation unit 34. According to FIGS. 3 and 4, the total value of the power consumption at home and the power consumption at the store is highest at 14:00. The electricity price menu creation unit 36 sets a time zone having a relatively high total value including the 14:00 range as a time zone to which a higher unit price is applied. In the example shown in FIGS. 3 and 4, the electricity price menu creation unit 36 sets a time zone from 10:00 to 16:00 as a time zone to which a higher unit price is applied.

  Furthermore, the electricity rate menu creation unit 36 obtains an average value of the combined power consumption in each time zone from 10:00 to 16:00. According to FIGS. 3 and 4, 11.6 kWh is calculated as an average value. Next, the electricity price menu creation unit 36 multiplies the average value by a coefficient value for determining the target power consumption. In the example shown in FIGS. 3 and 4, for example, a 10% increase of the average value is set as the target power consumption. Note that the decimal part is rounded up. In the example shown in FIGS. 3 and 4, since 11.6 × 1.1 = 12.76, 13 kWh is set as the target electricity usage amount.

  As a result, in the time zone from 10:00 to 16:00, a normal unit price is applied until the amount of electricity used reaches 13 kWh, and a unit price that is higher than the amount of electricity used exceeds 13 kWh. Applied. In the example shown in FIG. 3 and FIG. 4, since the power consumption at 14:00 is 14 kWh, which is 1 kWh higher than the target power consumption 13 kWh, a higher unit price is applied to this 1 kWh.

  In addition, the electricity price menu creation unit 36 sets the time zone from 10 o'clock to 16 o'clock as the time zone to which the expensive unit price is applied, but other time zones, that is, from 0 o'clock to 9 o'clock. The time zone in which the unit price is set so that the electricity rate is discounted between the hour zone and the 17:00 to 23:00 zone is set. For example, the electricity price menu creation unit 36 analyzes the power usage pattern estimated by the power usage pattern estimation unit 35, and the electricity price is reduced so as to include a time zone that is beneficial to both the customer and the power company. Set the time zone when the unit price is applied. The target power consumption is set in the same time zone as when the higher unit price is applied even during the time period when the lower unit price is applied, and the unit price is lower for the power consumption exceeding the target power consumption. Applies.

  FIG. 5 is a diagram showing an example of the unit price by time zone, FIG. 5A shows an example of a normal unit price by time zone for one day, and FIG. It is a figure which shows the unit price classified by time in the electricity bill menu which the preparation part produced.

  As shown in FIG. 5, the time zone in which the unit price is different in one day is as follows: 0 o'clock (24 o'clock)-7 o'clock and 23 o'clock nighttime, 8 o'clock-9 o'clock and 17 o'clock It is divided into 22:00 family time and 10: 00-16: 00 daytime. The normal unit price in the examples shown in FIGS. 3 and 4 is set to 9 yen at night time, 23 yen at family time, and 28 yen at day time for both home and store, as shown in FIG. 5 (a).

  According to the electricity price menu presented to the customer created by the electricity price menu creation unit 36, as shown in FIG. 5B, there is no change in the unit price for the power consumption at home, and the unit price for the power consumption at the store. There is a change. That is, in daytime, the unit price is 28 yen until the amount of electricity used reaches 13 kWh, but the unit price for the amount exceeding 13 kWh is 35 yen. Moreover, a part of night time and the unit price of family time in the morning are set at a discount.

  As a result, after the customer adopts the electricity price menu created by the electricity price menu creation unit 36, if the customer uses the power as before, the customer will pay a premium, which is disadvantageous for the customer. There is a possibility. However, if the customer is aware of the target power consumption and does not exceed the target power consumption, or if a part of the power used in daytime is sent to family time in the morning, the customer Makes it possible to use a cheap unit price of electricity, and can propose an electricity price menu that is beneficial to the customer. In addition, by making the customer aware of the target power consumption and not exceeding the target power consumption, the peak of the total power consumption can be lowered. For this reason, it is possible to reduce power consumption during daytime, which is a time zone when power consumption is high, which contributes to leveling of power consumption during peak power consumption, which is also beneficial for power companies. Can make suggestions.

  As described above, according to the present embodiment configured as described above, the power consumption amounts of a plurality of electric contracts classified as the same contractor or the same payer of electric charges are added up every hour. An electricity price menu that charges the electricity charges that exceed the target electricity consumption in a predetermined time period including the time period when the total value is the maximum peak, and discounts the electricity charges in other time periods To a customer who is the same contractor or the same payer of a plurality of electric contracts. As a result, customers can make efforts to reduce the amount of power used in the peak time period, and make up for the reduced power consumption in other time zones, so that the same power consumption can be achieved. Electricity charges can be kept low. Moreover, for the electric power company, the amount of power used in the time zone where the maximum peak is reached can be reduced. In this way, it is possible to propose an electricity price menu that has advantages for both customers and power companies.

  In addition, according to the present embodiment, the electricity price menu creation unit 36 sets the target power consumption amount for a predetermined time period based on the average value of the electricity charges for the predetermined time period, and further, the actual electric charge for use is determined. In the predetermined time zone, the unit price to be applied to the power consumption exceeding the target power consumption is set to be high. For this reason, by working to prevent the power consumption in the predetermined time zone from exceeding the target power consumption, the power usage in the peak time zone approaches the target power usage and reaches the maximum peak. The amount of power used in the time zone is leveled. As a result, stable power supply at the peak time can be performed.

  Further, according to the present embodiment, the additional service providing unit 37 is provided, and the power usage pattern estimated by the power usage pattern estimation unit 35 is compared with the power usage amount sequentially transmitted from the smart meter 10. When it is determined whether or not the current power consumption is abnormal, and when it is determined that it is abnormal, information to that effect is transmitted to the smart meter 10 or emailed to the customer's mobile terminal You can propose a service to do. Thus, for example, when the industry code is set for only one of the two electric contracts, for example, when the two electric contracts are for home use and for business use, the customer moves between the home and the store. It can be estimated that there is a certain time zone. That is, in the example shown in FIG. 3, it can be estimated that the customer is moving from 7:00 to 8:00 and from 17:00 to 18:00. Therefore, while the customer is moving, it is possible to provide information to the customer that there is a possibility of electric leakage or unauthorized use at either the home or the store, or that there is a planned power outage in the area between the two bases. .

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. For example, in the above-described embodiment, the case where the customer is self-employed and has an electric contract with the home in the name of the principal and the store in the name of the principal away from the home has been described as an example. It is not limited to that. For example, a customer's son lives alone in an apartment, and an electric company has an electricity contract for the use of electricity in the apartment with the customer's son, but the customer is billed for payment of electricity charges. If so, the customer will pay for home electricity and son's apartment. Even for such a plurality of electricity contracts with the same payer, it is possible to provide information that is beneficial to the customer by presenting the electricity price menu created by the electricity price menu creation unit 36 to the customer.

  In the above-described embodiment, the case where the same contractor has two electric contracts has been described as an example. However, the present invention is applicable even when three or more electric contracts are concluded.
