Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem wherein, although low voltage electricity demanders and high voltage electricity demanders are allowed to select contract types from electricity price menus presented by general electricity utilities by the electricity utilities industry law, the electricity utilities actually assign such types unilaterally, and there are no companies which provide alternatives for other contracts, so that the electricity demanders have no means to select arbitrary electricity price menus paid to the electricity utilities. <P>SOLUTION: By a business model of providing a new electricity price menu, on the Internet, for joint purchase in units of high tension distribution lines of a distribution substation of a general electricity utility, an electricity retailing broker accepts as an agent a mandate of each electricity demander for an electricity supplier choice right to form an electricity joint purchase organization and broker electricity retailing. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a commercial transaction system that combines a personal computer, a mobile phone, a mobile terminal, a server, a communication line, and the like necessary for a power retail commercial transaction using the Internet.

The general electric utility reads the electricity meter guidelines installed in each consumer every month and inputs the readings into the mobile terminal and the electricity bill calculation computer to determine the electricity usage for the current month. , Calculate and charge the electricity bill according to the usage.
The conventional electricity retailing method contracts the applicable price menus set by general electric utilities, and the amount of power used is paid in a post-payment method. This is a method of settlement by direct debit.

All electricity consumers in Japan are regulated by the Electricity Business Law, and there are regulations on how to contract with electric power companies. Generally, the electricity business is conducted for each independent household or corporation account. Purchased alone from the party. In other words, the person who wants to purchase electricity selects an appropriate one from the price menu presented by the electric power company, and concludes a supply and demand contract with the electric power company.
In this method, since there is only one menu that is assumed in advance for each electricity consumer, there is no means for each consumer to select an electricity price. For electricity consumers, there were no options for contracts and no diversification was allowed.
Actually, the tariff menu to be applied by the electric power company for the application of the electric power consumer was determined. Even if electricity consumers were dissatisfied with this decision, there was no means to resist.

In order to conduct business transactions related to electricity trading, the present invention uses the Internet to newly establish the role of a power retail broker, mediate contracts between low-voltage consumers or high-voltage consumers and electric utilities, Prepare the mechanism.
The role of the electricity retail broker is to enter into a contract for delegation of the right to purchase electricity with low-voltage customers or high-voltage customers, and to act as an agent.

  The present invention is based on the condition that a plurality of low-voltage customers or high-voltage customers are receiving power from the distribution lines of the same distribution substation, and the condition of joint purchase is to stop the single purchase for each customer, and the total demand for each line. Is treated as one electricity consumer, and a single power receiving contract is made with an electric power company.

  In order to make one contract for each line of the distribution line, the electricity retail brokerage agency solicits low-voltage customers or high-voltage customers who are willing to purchase jointly, and forms an electric joint purchase organization. Become a member. When the purchase scale of the electric joint purchasing organization reaches a certain amount, the electric power retail broker exercises the electric purchaser selection right in a lump.

  When a corporation such as a corporation is receiving power from a distribution line that is subject to joint purchase, when joining an electrical joint purchasing organization, a power retail broker will conclude a delegation contract for the option to purchase electricity and become a member of the joint electrical purchasing organization. Treat as.

In an area where electric power retail is liberalized, electric power retail brokers present purchase conditions to a plurality of electric power companies, and negotiate contract contents by an arbitrary contract method.
As an agent representing the will of the electricity joint purchasing organization, the electricity retail broker negotiates a supply and demand contract with the electric power company and concludes it on terms favorable to the members.

Electricity retail brokers use the power condition of the high-voltage distribution line drawn from the distribution substation as the transaction condition, and the contract condition when negotiating the electricity price menu with the electric utility.
For example, even if it is a low voltage consumer, if it becomes a member of an electric joint purchase organization, it can purchase as cheaply as a high voltage charge by selecting the electricity price menu of an electric power retail broker.

The electricity retail broker sets its own electricity price menu based on the actual electricity usage data of each member of the electricity joint purchasing organization. The electricity usage data for each member is transmitted to the server of the electricity retail broker via the Internet, and stored in the customer management / fee calculation database in FIG. 5 and the sales management database in FIG.
The electricity retail broker decides the amount of electricity used for each member, calculates the electricity bill, notifies it via the Internet, and collects the electricity bill.

  Members make monthly purchase reservations for each year by showing the planned usage amount to the electricity retail broker. This data is the basic condition for a power retail broker to negotiate a supply and demand contract with an electric utility.

The member pays the amount of electricity to be used according to the agreement indicated by the contract with the power retail broker, on the specified day of the previous month, the specified month, or the following month.
This electricity charge is a contract charge that applies the discount described in the contract. After that, if the previous month of the month or the payment month is the payment date, the electricity bill is settled when the actual amount of electricity actually used is fixed.

  If the actual usage amount is less than the planned usage amount, the discount contract is automatically changed, and the settled amount is subtracted from the next month bill. When the scheduled usage amount is exceeded, the shortage of electricity charges will be added to the next month's bill.

  In addition to monthly discounts on discounts conducted by power retail brokers for members, a method of receiving a total of the discounted amount for one year without reducing monthly electricity charges, and a power retail broker The method of receiving any service indicated by can be selected.

  When an electric power retail broker receives a bill for an electric charge for joint purchase from an electric power company, it pays the electric charge for all members in a lump sum by the designated date for each contract.

As described above, the present invention is only a system in which a low-voltage consumer or a high-voltage consumer contracts with an electric power company alone, and eliminates the state where the contract system is practically limited to one type.
According to the present invention, reference numerals ML1 and ML2 are watt-hour meters installed on the premises of electricity consumers in FIG. , ML3, and ML4 are changed to reference numeral MH3, which is a power meter on the supply side of the high-voltage distribution line installed in the distribution substation of the electric power company.
As a result, in the case of a low voltage customer, the voltage classification in the commercial transaction for electricity trading can be changed to the electricity rate contract menu in the high voltage field in the joint purchase method, although it was in the low voltage field in the single contract.

  High-voltage consumers who have signed a contract with an electric power company can purchase electricity under more advantageous conditions because a power retail broker enters into a purchase contract for each line of the high-voltage distribution line.

In the liberalization field where business regulations under the Electricity Business Law have been relaxed, the contract form and the electricity price menu can be selected at the will of the electricity customer through negotiations with the electricity supplier. However, it is clear that it is extremely difficult for low-voltage consumers or high-voltage consumers to individually change the contract form with electric power companies because the dominance in the market is very large.
The present invention establishes a commercial transaction acting as a new business method called a power retail brokerage business, acting on behalf of a contract with general electric companies that have almost monopolized the market or specific scale electric power companies that have newly entered the power retail market, The aim is to contribute to the equalization of Japan's electricity market, ensuring transparency of transactions, and stabilization of supply and demand by enhancing the market power on the customer side.

The best mode for carrying out the invention will be described with reference to the drawings.
The most important point of the present invention is that an electricity consumer for each high-voltage distribution line owned by an electric power company shows an intention to purchase jointly and forms an economic community for realizing a specific purpose.
The representative of this community is a power retail brokerage agency commissioned by electricity consumers, and this power retail brokerage business is constructed as an indispensable system for achieving business objectives via the Internet or the like.
When an electric consumer connects himself / herself with a power retail broker, data is sent to the server of the power retail broker via the La communication line in FIG. When the intermediate manager connects to the power retail broker, data is sent to the server of the electric retail broker via the communication line Lb in FIG. In the following description, all the data transmission / reception methods are the same.
