Description

  The present invention relates to a power charge calculation system, a power charge calculation method, a power charge calculation program used therefor, and a recording medium recording the same, and more specifically, family members or household members are located at a plurality of locations. The present invention relates to a power charge calculation system that calculates a power charge for each family or household.

  Japan's power supply system is characterized by a so-called nine-power system that divides the nation excluding Okinawa into nine supply regions and has supply rights and supply obligations for each region. As shown in Figure 1, the nine electric power companies consist of electric power companies in Hokkaido, Tohoku, Tokyo, Chubu, Hokuriku, Kansai, China (the applicant), Shikoku, and Kyushu (Okinawa is supplied by Okinawa Electric Power) ). These electric power companies (hereinafter also referred to as “electric power suppliers” and “electric power supply companies”) generate power using energy such as nuclear power, thermal power, and hydroelectric power, and in case of emergency, receive power from other companies and provide interchange. The company strives to provide a stable supply to electricity consumers (hereinafter also referred to as “customers” and “consumers”) in its own supply area.

  In the calculation of the value of the power supply, that is, the power charge calculation system, a pay-as-you-go system according to the amount of use is generally adopted. That is, it is determined by the total of the basic charge according to the contract type (used power) and the contracted capacity (used amperage) and the used power charge within the usage period (the period from the previous meter reading to the current meter reading). Yes. Basic charges are determined in units of households at the place where electricity is used, and in general, because one household or family (hereinafter simply referred to as “one household”) resides in one house. Yes.

  Regarding the form of households in Japan, there were many large families in the past, and there were many cases where about three generations lived together. In such a case, the basic charge should be paid for one basic charge.

  In recent years, the form of households has shifted to nuclear families (nuclear households). For this reason, compared with the form of a large family, the basic fee charged for each household is more expensive.

  Furthermore, as shown in FIG. 2, due to recent social circumstances, for example, due to circumstances such as relocation at a company, the location of a child's educational institution, etc., the home of the household is in Hiroshima City, and the father is relocated to Kitakyushu City due to relocation. It is often the case that the eldest son goes to Tokyo University and the eldest daughter goes to Kyoto University.

  Such a situation is not limited to the case of straddling a plurality of power supply areas, but also occurs in the same supply area where the same power supply company supplies power. For example, if your family was originally from Kure City and your father built a home in Hiroshima City, you can often see an old grandparent who still lives in Kure City. In such a case, a situation occurs in which members in the range where the father bears the electricity bill use power at a plurality of locations in the same power supply area.

When such household members live in various places, as a power supplier, their home is China Electric Power, their father's new residence is Kyushu Electric Power, and the eldest son's apartment is Tokyo Electric Power, The eldest daughter's apartment is Kansai Electric Power, and her grandparent's residence is Chinese electric power. From the household side, power is supplied from a plurality of power companies, and a basic fee is paid to each of the power companies. A household where the grandparents live together and the father does not leave the house alone, or the household members who have lived in a single house before the child entered the urban university For the main, there is a sense of being overpriced for the basic fee collected for each household member's location.

  In addition, payment financial institutions used for payment of electricity charges are, for example, at home from Hiroshima Bank to Chugoku Electric Power, father to Kitakyushu Bank to Kyushu Electric Power, and the eldest son to Tokyo Electric Power through Tokyo Bank. Must go to Kansai Electric Power through Kyoto Bank and grandparents to Chugoku Electric Power through Hiroshima Bank. For this reason, the settlement fee (transfer fee) of the financial institution is also duplicated.

  Under the social circumstances where household members have to live in a decentralized environment due to the above-mentioned social circumstances, it is desirable to provide a fair electricity rate calculation system, etc. Yes.

  From the viewpoint of the household, it is desirable to provide a power charge calculation / collection system that enables the power charge bearer to collectively pay the power charges of household members living in a distributed manner.

In the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted.
[Electricity charge calculation system]
Fig. 1 is a diagram for explaining Japan's nine power systems explained earlier. The nation except Okinawa is divided into nine supply regions, and nine power supply companies have supply rights and supply obligations for each region. As shown in the box, 9 electric power companies are made up of electric power companies in Hokkaido, Tohoku, Tokyo, Chubu, Hokuriku, Kansai, China (the applicant), Shikoku, and Kyushu. It is the block diagram which showed the outline | summary of the electric power charge calculation system which concerns on a present Example which each of 9 electric power supply companies shown by can employ | adopt. The portion on the left side of the broken line shows the power rate calculation system of the A power supply company. The portion on the right side of the broken line in the figure shows the power charge calculation system of the B power supply company, but in order to simplify the drawing, only the charge calculation center and the host computer are shown and the others are omitted. However, it should be noted that the power charge calculation system of the B power supply company has the same configuration as that of the A power supply company. Further, after the C power supply company, other power supply companies also have a system similar to the power charge calculation system of the A and B power supply companies.

  First, the left side of the broken line in FIG. 3 will be described. For example, the power charge calculation system that can be adopted by the A power supply company is based on the locations of a plurality of customers 1-1, 1-2,. A portable terminal 7 for transmitting / receiving meter-reading data relating to charge calculation to / from a power supply system through a line (network), and a database 6 storing various data for power calculation, power charge calculation results, power charge collection data, etc. And a host computer system 4 on the power supply side having a host computer 5, a computer system 3 installed in a customer center serving as a window for the customer 1, connected to the host computer system 4, and a mobile terminal 7 Calculation of electricity charges based on meter reading data and customer data stored in the database 6 in the host computer system 4 A financial institution connected to the host computer system 4 that performs charge collection work from each customer based on instructions / information from the host computer system 4 and a computer 9 of the charge calculation center connected to the host computer system 4 A computer system 12 such as a financial institution at a convenience store (abbreviation of “convenience store”).

  The B power supply company has a similar power charge calculation system, but only the charge center 9-1 and the host computer center 4-1 are shown on the right side of FIG.

  A plurality of customers 1-1, 1-2, 1-3, 1-4,..., 1-n in FIG. In the following description, these multiple customers may be described as customers 1 unless otherwise misunderstood. Here, suppose that the customer 1-1 is a mother residing in a home in Hiroshima City and the customer 1-3 is a grandparent residing in Kure City, with reference to FIG. The residence of the mother and the residence of the grandparents are the same power supply area of China Electric Power (A power supply company).

On the other hand, the father residing in Kitakyushu is a customer of Kyushu Electric Power (B power supply company), the eldest son residing in Tokyo is a customer of Tokyo Electric Power (C power supply company), and the grandparents residing in Kyoto are Kansai. A customer of electric power (D power supply company).

  A watt hour meter (not shown; also referred to as “integrated watt hour meter”) is provided at a power transmission lead-in end of each customer 1 such as a house. This watt-hour meter displays the amount of power used by the customer 1 (unit is generally kilowatt hour [kWH]) cumulatively.

  A meter reader periodically visits the customer 1-1, 1-2, 1-3, 1-4,..., 1-n, and visits the mobile terminal 7 to read the watt-hour meter. The meter reading data is transmitted from the portable terminal 7 to the charge calculation center 9 through the network line 8, for example.

  The network line 8 can use various wired lines or wireless lines such as public telephone lines, ISDN, and Internet lines.

  The power supplier generally has a computer system 3 in a customer center which is a window for the customer 1. As this customer center, a plurality of centers are usually provided in the power supply area in consideration of the convenience of many customers. However, for the sake of simplicity, only a single customer center is illustrated and described here. To do.

  Further, the power supplier has a computer system 9 in the charge calculation center. This computer system 9 is connected to the host computer system 4 of the power supplier and uses various data stored in the database 6 of the host computer system 4 for each customer, and finally for each household. The customer 1 is calculating power usage charges. The calculation results are sequentially stored in the database 6 of the host computer system 4.

  The host computer system 4 usually has a medium-sized or large-sized host computer 5 and a database 6 connected thereto. This database 6 has various files relating to the power charges.

  As described above, although not shown in the figure, other power supply companies also have a system similar to the power calculation system of the A power company, and the computer systems 9, 9-1, 9-2,. 9-n are connected to each other via a line 15. The line 15 may be any line that can transmit and receive data between calculation centers, and may be either wired or wireless. For example, a network such as a public telephone line, a dedicated line, ISDN, ADSL, an optical cable, and the Internet may be used. Available.

  FIG. 4 shows an example of data stored in the database 6. A charge calculation master file 21, a customer information file 22, a meter reading information file 23, a collection / accrual information file 24, a sales record file 25, and other files 26 are stored in the database 6. Have.

  FIG. 5 shows an example of the charge calculation master data 21, in which one record is assigned to each household, data necessary for charge calculation for each household is accumulated and sequentially updated. The charge calculation master information includes, for example, a header 210, household identification information (household ID) 211, customer identification information (customer (b) ID 212), customer (b) data 213, customer (b) ID 214, customer (b) data. 215, customer (c) ID 216, customer (c) data 217, etc. (218), and other 219 data. Customer (I)... Customer (C) indicates members of each household in FIG. Further, the combinations of customer IDs and customer data are repeatedly secured as many times as necessary.

Here, one household ID 211 is assigned to all household members (all fathers, mothers, eldest sons, eldest daughters, and grandparents in FIG. 2) that are borne by the power charge bearers in the range shown in FIG. ing. On the other hand, the customer ID is assigned to each power user (that is, in FIG. 2, each of the father, mother, eldest son, eldest daughter, and grandparent).

  Furthermore, a part of the household ID 211, preferably the first few bits to more than a dozen bits, can be used to identify the power supply company. For example, as shown in FIG. 13, under the current nine power system, the first 4 bits are (0000) Hokkaido Electric Power, (0001) Tohoku Electric Power, (0010) Tokyo Electric Power, ..., (0110) Chinese Electric Power, ... Grant as follows. Subsequent bits are used as serial numbers for each household in the power supply area. In this way, by including information identifying the power company in charge of power supply in a part of the household ID, the power supply company in charge of the final power collection of the household can easily be made between the power supply companies. Can be identified. However, the household ID and the identification code of the power supply company in charge of the charge collection business may be given separately.

  FIG. 6 shows a customer information file 22 in which customer data input mainly from the computer system 3 at the customer center is stored. As customer information, for example, one record is assigned to each customer (that is, for each household member), header 220, household ID 221, customer (x) ID 222, customer (x) name 223, power usage location 224, contract A type 225, a contract capacity 226, and other data 227 are included. Customer (x) is one of the household members in FIG.

  FIG. 7 shows a meter reading information file 14 which is one of the item-specific files. Data input from the portable terminal 7 to the computer system 9 of the charge calculation center via the network 8 is transferred and accumulated. As meter reading data, one record is assigned to each customer (x). For example, header 230, household ID 231, customer (x) ID 232, previous meter reading date 233, current meter reading date 234, (from previous meter reading date to current meter reading date) Use period 235, the current instruction number 236 indicated by the watt-hour meter installed at the location of the customer (x), the previous instruction number 237, and the subtraction 238 (representing the electric energy used within the use period 234) And other data 239. In general, the electricity usage fee is collected on a monthly basis, but the unit period of the fee collection is not limited to this. This unit period is arbitrarily determined based on a contract between the power supply side and the power usage side.

  The files shown in FIGS. 8 and 9 are basically provided for each household in the system of the power supply company contracted by the power charge bearer. FIG. 8 shows a collection / accrual information file 24, which is one of the item-specific files, in which the collection / accrual data of power charges input from computer systems 3 and 12 such as customer centers and financial institutions are accumulated. . As the collected / unaccounted data, one record is assigned to each household. For example, header 240, household ID 241, customer ID 242 who bears the electricity bill, automatic transfer possibility 243, financial institution name 244, account number 245, automatic There are a transfer situation 246, a window payment situation 247, and others 248.

  FIG. 9 shows a sales record information file 25 that is one of the item-specific files, and is data in which the data of the collection / accrual information file 24 in which the data for this time is accumulated is retroactively accumulated. As sales performance information data, one record is assigned to each household. For example, header 250, household ID 251, customer ID 252 who is a power charge bearer, current charge 253, collection status 254, previous charge 255, collection status 256, There is a charge 257, a collection status 258, and others 259.

  The charge master file 6 shown in FIG. 4 stores the data shown in FIGS. 10 to 12 as other files 26 other than this.

FIG. 10 is a basic charge table stored in the other file 26. For the basic charge portion of the power charge, a basic charge (kWH (B)) is determined in advance for each contract type and contract capacity.

  FIG. 11 is a graph for determining the power consumption charges accumulated in the other file 26. As for the usage charge part of the power charge, in general, the fixed power charge unit price F is constant regardless of the amount of power used, and the variable power charge unit price increases gradually when the power consumption increases. There is V. The fixed power unit price F or the variable power unit price V with respect to the amount of power used is digitized and stored in a table. The fixed unit price F and the variable unit price V are both examples, and which one is adopted is determined by a contract between the power supplier and the consumer or the like.

  FIG. 12 is a table showing the relationship between the number of household members (N) and the coefficient (K) that determines the reduction rate for the basic charge portion. In the example of FIG. 12, for the first household member (mother in FIG. 2), the basic fee portion is 100% collected (coefficient K = 1.00 for the basic fee). For the second person (father in FIG. 2) 50% (K = 0.50), for the third person (oldest son in FIG. 2) 25% (K = 0.25), for the fourth person (older daughter in FIG. 2) 13% (K = 0.13), the fifth person (grandparent in FIG. 2) is 6% (K = 0.06), and the sixth and subsequent persons are 0% (K = 0).

  For example, if the basic fee is collected once for one household, it may be 0% (K = 0) for the second and subsequent persons. The coefficient K can be freely determined. When multiple household members in the same household use electricity in different locations, how much the basic charge for the second and subsequent persons is determined depends on the business and management judgments of the power supply company. In addition, when household members straddle different power supply areas, it is necessary to finally redistribute the power charges collected in one household to multiple power companies that have supplied power. There is. Therefore, the coefficient K needs to be determined upon agreement between the respective power supply companies.

  The data shown in FIGS. 10 to 12 will be described in detail when the household unit electricity rate calculation system is described below.

  Referring again to FIG. 3, a computer system 12 such as a financial institution is connected to the host computer system 4 of the power supplier, obtains a power charge calculation result from the host computer system 4, and takes charge of a power charge collection operation. Recently, not only financial institutions but also convenience stores and the like are equipped with simple computer systems, information terminals, etc., and carry out similar power charge collection operations.

  Depending on the power supply company, regarding the computer system 3 of the charge calculation center, the host computer system 4 and the computer system 9 of the customer center, any two or all systems may be integrated and operated in the same system. . Even in such a case, as long as the calculation of the household unit electricity charge can be executed, this embodiment is employed.

In the power charge calculation system shown in FIG. 3, the power charge used by the customer 1 is calculated by the power charge calculation method for each household, notified to each customer 1, collected from each customer 1, and further the entire operation of these is performed. I manage. Next, an explanation will be given of a method for calculating a power charge for each household and a method for collecting a power charge using the power charge calculation system described above.
[Calculation method for electricity consumption per household]
FIG. 14 is a diagram showing a power meter reading, a used power charge, a collected power charge, and a management procedure thereof in the household unit used power charge calculation system.

First, in step S101-1, a customer (for example, a mother in FIG. 2) 1-1 who bears a power charge makes a power usage contract at the customer center of the power supply company A. At this time, the customer 1-1 provides his / her information (household information, customer information) to the customer center. These household information and customer information include at least the householder's name (name of the person who bears the electricity charge), the customer's name, the place where the power is used, the contract type (large power for factories, medium-scale power for shops, small power for households, etc.) Type) and contracted capacity (discrimination of maximum used capacity such as 40 amps, 50 amps, 60 amps, etc.). These household information and customer information are input to the computer system 3 in the customer center.

  At this time, it is necessary to provide data on household members when it is desired to calculate the electricity rate for each household. For power supply companies, the household power calculation system is a kind of price reduction, so an endless expansion of the scope of application leads to a decrease in sales and must be avoided. On the other hand, a household member who really belongs to one household needs to appropriately calculate the power for each household and meet the needs. Therefore, a certain kind of verification system is required to determine whether or not the member is truly a household member.

  As one of the verification systems, for example, information described in a health insurance card can be used. In Japan today, a universal health insurance system has been established in which all citizens can join the medical insurance system in the workplace or in the community and receive treatment with a single health insurance card. The health insurance insured card lists the address, the name of the insured person (in many cases, the householder, that is, the person who bears the electricity fee), and the names of dependents who are household members. The household members residing outside their homes, such as the father, eldest son, eldest daughter, and grandparents in FIG. 2, each have a remote health insurance insurance card. In this way, by adopting the verification system based on the health insurance card, the power bearer (household owner) can identify the range of household members that bear the power charge. As a similar verification system, for example, a family register copy created by a public institution with the consent of the customer can be used. By adopting such a verification system, the power supply company can limit the reduction of basic charges to the range of household members who belong to a single household and prevent endless expansion.

  In step S102, the customer data obtained from the householder (the person who bears the electricity bill) is given a household ID and a customer ID, and is stored in the database 6 of the host computer system 4 from the computer system 3 at the customer center, and the customer information file 22 is created. Customer data as shown in FIG. 6 is created as the customer information file 22, and household ID 221, customer (x) ID 222, customer (x) name 223, usage location 224, contract type 225, contract as one record per customer. A capacity 226, other 228, and the like are stored. If necessary, this household ID 221 is notified to the customer 1-1. Further, when receiving a request for calculating the electricity charge for each household, the household ID is recorded in the household ID 211 of the charge calculation master data shown in FIG. 5, and the person who bears the electricity charge is recorded as the customer (I) ID 212. The range of other household members is specified and recorded as IDs of customers (b), (c), data 214, 215,.

  Similarly, in step S101-2, a customer 1-3 (grandparent) who is a household member makes a contract to use power at the customer center of the power supply company A. At this time, it is preferable to report the household ID 221 notified in advance. However, even when the household ID 221 is not notified, the computer system of the charge calculation center of each power supply company is connected to each other by presenting the remote health insurance insured card. Based on the company name, household head name, address, etc., the household ID registered in step S101-1 can be searched to identify the household ID. At this time, it is also possible to confirm whether or not the person who bears the power charge is a person who has agreed to pay the charge. Accordingly, customer data as shown in FIG. 6 is created through the same procedure. In addition, although not shown in figure, the other household members (father, eldest son, eldest daughter, etc.) shown in FIG. 2 perform the same procedure with respect to the electric power supply company of each residence place.

In step S103, many customers (power charge bearers) 1-1 are now requesting automatic transfer (automatic withdrawal) of power charges to financial institutions. As a result, the customer 1-1 can automatically pay the power charge. From the computer system 12 of the financial institution or the like that has received the automatic transfer request, to the collected / accrued information file 24 (FIG. 8) in the database 6 of the host computer system 4, whether or not automatic transfer is possible 243, financial institution name 244, account number 245 Etc. are transmitted and stored.

  In step S104-1, when the customer 1-1 is supplied with power from the power supplier for a predetermined period (for example, for one month), the meter reader of the power supplier takes the customer 1 while bringing the portable terminal 7. -1 and read the electricity meter installed in the house of the customer 1-1. At this time, the meter reader inputs meter reading data such as the customer ID and the current instruction number (meter reading data) to the portable terminal 7 and transmits it to the computer system 9 of the charge calculation center. Similarly, in step S104-2, the power consumption of the customer 1-3 is measured and transmitted from the portable terminal 7.

  In step 105, the computer system 9 of the charge calculation center transmits meter reading data to the host computer system 4, and in the meter reading information file 23 (FIG. 7) in the database 6, the current meter reading date 234 for each customer together with the customer ID. This time, it is recorded as the instruction number 236.

  Similarly, the meter-reading information file is created in the power rate calculation system of the power supply company in each residence place of the other household members (father, eldest son, eldest daughter, grandparent) shown in FIG.

  In step 106-1, the computer system 9 of the charge calculation center collects customer data with the same household ID stored in the database 6 of the host computer system 4. At this time, customer data of other household members (father, eldest son, eldest daughter, grandparent) with the same household ID are received from a computer system of a calculation center of another power supply company.

  The calculation of power charges for each household is performed as shown in FIG.

  In step S151, as described in step 106-1, customer data of all household members who have been notified in advance is collected. Each customer data includes household ID 221, customer (x) ID 222, customer (x) name 223, contract type 225, contract capacity 226, and household ID 231, customer (x) ID 232 shown in FIG. A subtraction 238 indicating the amount is included. These customer data are stored in the charge calculation master data (FIG. 5) of the power supply company in which the charge bearer resides as customer data (b), customer data (b),... Accumulated.

  Returning to FIG. 15, in step S152, it is determined whether customer data of all household members has been collected. Specifically, the determination is made based on whether or not the data of all household members notified in advance is accumulated in the charge calculation master data (FIG. 5).

  In step S153, when the data of all the household members is accumulated, household unit power calculation is executed. First, (basic charge) × coefficient + (use charge) = KWH (B) × K + KWH (U) is calculated for each customer.

  As shown in FIG. 10, the basic fee KWH (B) is determined from the basic fee table based on the contract type and the contract capacity. The usage fee is determined from the power consumption fee graph (FIG. 11) based on the subtraction (usage amount) collected as customer data. If the basic charge table and the used power charge table are different between each power supply company, the basic charge table and the used power charge table of all the power supply companies are prepared by exchanging with each other or by customers. These data are also collected at the time of data collection (S151).

The coefficient K is a factor that determines the reduction rate of the basic fee portion KWH (B) shown in FIG. For example, as shown in FIG. 2, as the number of household members increases, the second person, the third person,... Will be low.

  In step S154, when the power calculation for all members of the same household is completed, the power charges for each household are determined by summing them up.

  Returning to FIG. 14, in step 107, the computer system 9 of the charge calculation center stores the charge calculation result in the charge calculation master file 21 (FIG. 3) stored in the database 6 of the host computer system 4 as the power charge 218. accumulate.

  In step S108, the computer system 9 of the charge calculation center transmits the data on the electric power charge used for each household to the computer system 12 such as a financial institution. This transmission is performed via a dedicated line or a normal network 8. Thereafter, the billed amount is withdrawn from the deposit account of the power charge bearer.

  For customer 1 who has not made a request for automatic transfer to a financial institution, the bill is sent from the host computer system 4 to the person who pays the power charge in household units in step S109-1, using mail or the like. Will be sent. Alternatively, in step 119-2, a bill is sent from the computer system 12 such as a financial institution to the customer 1 by mail or the like. Whether the bill is sent by the power supply company or the financial institution depends on the contract between the two.

  In step 110-1, the customer 1 who has received the bill from the power supply company goes to the customer center and pays the fee.

  In step 110-2, the customer 1 who has received the bill from the financial institution or the like goes to the financial institution and pays the power fee.

  In step S111, the computer system 12 of the financial institution transmits this charge reduction result or payment status to the host computer 5 of the host computer system 4, and the host computer 5 collects the collected / accrued information file stored in the database 6. 24 (FIG. 8) is stored as the automatic transfer status 246 or the window payment status 247.

  In step 112, the customer center computer system 3 transmits the deposit status to the host computer 5 of the host computer system 4, and the host computer 5 collects the collected / accrued information file 24 stored in the database 6 (FIG. 8). Is stored as the window of deposit payment status 247.

  In step S113, the host computer 5 of the host computer system 4 sends the receipt 14 to the customer on a household basis in a timely manner after the payment of the power charge is confirmed.

  In this way, the power supply company that collects the electricity charges in units of households pays the electricity charges determined according to the power consumption of other household members to the power companies where other household members reside. I do.

  In addition to the above-mentioned household-based power charge calculation system and power charge calculation method, a program that allows the computer to read and execute the above-described procedure and a recording medium that records the program are also objects of the present invention.

  Here, it should be understood that the above-described power charge calculation system is an example.

  Other parameters can also be introduced in the calculation of electricity charges. Even in such a case, as long as the electricity charge calculation is performed for each household, this is an embodiment of the present invention.

  In addition, these various types of processing are sequentially changed with the development of various information processing systems and information processing devices, and for example, electronic payment using a network such as the Internet can be employed. Accordingly, it should be understood by those skilled in the art that improvements and modifications can be made according to the needs of the system. Even under such circumstances, any system capable of executing the power charge calculation of the present invention can be an embodiment of the present invention. The invention is limited only by the appended claims.

(Effect of embodiment)
According to the present embodiment, it is possible to provide a household-based power rate calculation system.
(1) Even if the form of household shifts to a nuclear family (nuclear household), the feeling of overpriced basic charges is reduced.
(2) Even when multiple household members live in the power supply areas of different power supply companies due to social circumstances, the basic charge part of the power charge is compared with the case where separate independence is calculated. Because the price is relatively low, the feeling of overpriced basic charges is reduced.
(3) This situation is the same when multiple household members live separately in the power supply area of the same power supply company.
(4) Furthermore, since the electricity charges are paid in a lump sum at the household level, it is possible to avoid the burden of overlapping settlement fees (transfer fees) of financial institutions.
(5) Viewed from the household side, the person who bears the power charge can specify the household members who live in a dispersed manner and pay the power charge at once.
(6) Since the power supply company also has a verification system for whether or not it is a true household member, it is possible to prevent endless expansion of the reduction of basic charges.
