[0010] Hereinafter, an embodiment of the power procurement system of the present invention will be described.

[0011] In the power procurement system of this embodiment, power generation facilities (for example, solar panels are assumed, but this is not limited to this, and may also be thermal power generation facilities, storage batteries, etc.) are broken down into smaller units using security tokens (ST, Security Token), allowing for compartmentalized ownership, thereby reducing the initial investment required to own the power generation facilities. Furthermore, the power procurement system of this embodiment realizes a marketplace that enables high-frequency trading, where tokens are held only when in use. This, for example, can eliminate the paid-for use status of power generation facilities, price the power generation facilities in the secondary market, ensure liquidity, and increase the value of the power generation facilities. By compartmentalizing power generation facilities, power consumers can transmit electricity from the power generation facilities they own to power demand facilities using a self-wheeling system.

[0012] While private power generation facilities are generally owned by a single business or individual, this embodiment employs a model in which a single power generation facility is jointly owned by multiple consumers.

[0013] Traditional large-scale power generation facilities (not only solar, but also thermal and wind power) require high initial investment costs, making them a significant burden for a single business owner. Furthermore, some facilities are only used for daytime peak shaving and often idle, creating a need for increased utilization rates. Furthermore, for power generation facilities that are difficult to adjust output for short periods, excess power generation can occur when demand facilities are not operating, leaving businesses with no choice but to sell the electricity to other companies, even at uneconomical prices. To improve economic viability, there is no mechanism for increasing liquidity, such as by selling the ownership of the facility and allowing the purchaser to use a self-consignment system. Furthermore, even if joint ownership were actually implemented, the only applicable power generation facility would be solar power generation facilities, which physically separate the ownership units and install meters on each unit to measure the amount of power generated. Even if joint ownership were implemented, the installation of multiple meters would likely result in poor economic viability. Furthermore, even if a large-scale solar power generation facility were physically divided and owned, differences in solar radiation and panel deterioration would result in different amounts of power generated at different measurement points, even if the same panel area was owned, resulting in inequity. Furthermore, this method of physically separating the energy sources has been difficult to apply to other types of power generation facilities (thermal, hydroelectric, wind, geothermal, biomass, nuclear, other power generation methods, and batteries). While solar panels can be physically separated into individual panels, it has been difficult to achieve such a physical separation for other types of power generation facilities.

[0014] Therefore, in the power procurement system of this embodiment, power generation facilities are divided virtually, not physically, and the divided sections are represented by blockchain tokens, allowing users of the power generation facilities to hold ownership of each divided unit. This makes it possible to own a portion of expensive power generation facilities for a small amount, and because the division is virtual, it also makes it possible to own power generation facilities other than solar power generation facilities, which have physical restrictions on division, in parts.

[0015] In addition, the power procurement system of this embodiment measures the amount of power generated by the power generation equipment and supplies the amount of power (kWh) in the form of self-consignment according to the proportion of power it has held within a certain time period (e.g., every 30 minutes).

[0016] In addition, the electricity procurement system of this embodiment makes it easier to buy and sell by electronically recording the percentage of power generation equipment owned, and by providing a platform where ownership and the offtake rights for the associated amount of electricity (kWh) can be bought and sold, it increases the liquidity of assets, and at the same time, by placing existing equipment on the platform, it is possible to improve the equipment operating rate.

[0017] In this way, according to the power procurement system of this embodiment, by dividing the tokens, it is possible to own power generation facilities with a small initial investment.

[0018] Furthermore, the electricity procurement system of this embodiment allows for the realization of a high-frequency token trading platform, enabling operations such as selling only during times when the power generation facility is not in use. This adds the option of selling or temporarily selling to the previously rigid ownership structure of power generation facilities, which is expected to stimulate asset investment. This ensures asset liquidity and increases asset value.

[0019] Furthermore, according to the power procurement system of this embodiment, rather than physically separating actual power generation facilities (it is difficult to physically separate facilities other than solar panels in the first place), it is possible to realize a mechanism that combines virtually divided ownership rights using tokens with offtake rights for electricity (kWh). Therefore, there are no restrictions on the power generation facilities that can be jointly owned, and it is applicable to all power generation methods, including thermal power, hydroelectric power, wind power, geothermal power, biomass power, and nuclear power, as well as storage batteries.

[0020] Furthermore, with the power procurement system of this embodiment, it is possible to temporarily sell unused power generation facilities, such as those used only during certain seasons or times at factories. Therefore, even if there are times when the power load is not in operation, the power generation facilities can be operated continuously and profits can be enjoyed. This is expected to improve the facility's operating rate, and as an added effect, it will reduce the total operating costs for power generation in Japan and improve the economics of owning power generation facilities (consumers who need short-term power procurement, such as for peak shaving, can use this system regardless of the size of demand, so there is a possibility that they can sell electricity at a higher price than selling it to a regular power company).

[0021] In addition, by virtually dividing the ownership of the power generation facility, unfairness among owners due to differences in the amount of power generated due to the deterioration of each panel or differences in the amount of sunlight will no longer occur. This will eliminate the unfairness caused by fluctuations in the amount of power generated between solar panels, as seen in conventional community solar systems.

[0022] <Outline of electricity procurement> FIG. 1 is a diagram illustrating an overview of power procurement in the first embodiment. A consumer 10 (company A) owns a demand facility 11 and procures power for use at the demand facility 11 by virtually dividing a power generation facility 13 into sections 131 from a marketplace 12. The power generated by the power generation facility 13 is divided according to the share of the power generation facility 13 and supplied to the demand facility 11 by self-dispatch. While the power is actually transmitted by the power transmission utility, a portion of the power generated by the power generation facility 13 is virtually considered to have been transmitted to the demand facility 11. Self-dispatch refers to a service provided by a general power transmission and distribution utility when a person who installs a private power generation facility transmits electricity generated using the private power generation facility to a factory or other facility located elsewhere of the person who installs the private power generation facility via a transmission and distribution network maintained and operated by the general power transmission and distribution utility. The existence of the marketplace 12 ensures the liquidity of the power generation facility 13 (or its division), allowing the consumer 10 to acquire the necessary percentage of shares when necessary and perform self-transportation from the private power generation facility 13.

[0023] Figure 2 is a diagram illustrating a conventional form of joint ownership of solar panels. Conventionally, when solar panels are jointly owned, the unit owners own the power generation equipment 13 (solar panels) in physically divided units, and a smart meter 14 is installed for each physical unit 131 to manage the amount of power generated by each unit 131.

[0024] FIG. 3 is a diagram illustrating a joint ownership form of the power generation facility 13 according to the first embodiment. In the example of FIG. 3, only one smart meter 14 is installed in the power generation facility 13, and the amount of power generated by the entire power generation facility 13 is measured. Here, it is assumed that 100 tokens are issued by the ST for the power generation facility 13. The power generation facility 13 is jointly owned by four companies, A, B, C, and D, and their respective ownership interests are 60%, 10%, 20%, and 10%, respectively. In this case, Company A holds 60 tokens, Company B holds 10 tokens, Company C holds 20 tokens, and Company D holds 10 tokens, which can prove their ownership ratios. According to this ratio, the amount of power generated by the power generation facility 13 (measured by the smart meter 14) is also divided and deemed to have been self-consigned to each company. Here, even if, in another time period, Company A sells 30 tokens, Company B purchases an additional 30 tokens, Company C sells 10 tokens, and Company E purchases 10 tokens, the amount of power generated by the power generation facility 13 can be considered to be virtually divided and self-consigned to each company according to the token holding ratio. Note that the amount of power can be measured and allocated for each time period of a predetermined length (for example, 30 minutes). Note that the length of the time period can be different depending on the market.

[0025] FIG. 4 is a diagram illustrating the distribution of generated power. In the example of FIG. 4, the transition of the amount of power generated from the power generation facility 13 is shown by a curve 141. If the power generation facility 13 generates 30 kWh at 12:00 (a time period of 30 minutes from 12:00), and Company A holds 60 of the 100 tokens and Company B holds 10 of the 100 tokens, the amount of power procured by Company A is 30 kWh × 60 / 100 = 18 kWh, and the amount of power procured by Company B is 30 kWh × 10 / 100 = 3 kWh. Similarly, if the power generation facility 13 generates 20 kWh at 18:00, and Company A holds 30 tokens and Company B holds 40 tokens during that time period, the amount of power procured by Company A is 20 kWh × 30 / 100 = 6 kWh, and the amount of power procured by Company B is 20 kWh × 40 / 100 = 8 kWh.

[0026] 5 is a diagram showing an overview of transactions in the electricity procurement system of the first embodiment. In the marketplace 12 (trading platform), information about power generation facilities 13 is registered by a facility provider 15, and tokens are issued (asset registration). Then, a consumer 11 who will be the seller of the token registers the conditions under which he or she wishes to sell the facility, and a consumer 11 who will be the purchaser of the token sets conditions such as the power generation type (PV, wind power, etc.) of the power generation facility 13 he or she wishes to purchase, as well as the amount of power, price, time period, and region (the superiority or inferiority of the conditions can also be set), and matching 121 of a classification 131 of the power generation facility 13 is performed in the marketplace 12. Matching will be performed (reservation of purchase and sale) in each slot every 30 minutes from now (based on the current unit time of power measurement; if the unit time changes, it will be based on the new specified unit time), and when the actual date reaches the time of the slot, ownership (and offtake rights) of division 131 of power generation facility 13 will be transferred from the seller to the purchaser, and the transfer of ownership (and offtake rights) will be proven by transferring an amount of tokens corresponding to the ownership ratio of division 131 to the wallet of the purchaser's consumer 10. In addition, marketplace 12 automatically calculates the amount of power generation (forecast value, actual value) and the amount of offtake of power (kWh) corresponding to the token holding ratio, records the amount of power generation (power generation forecast, actual), and can create reports for the Organization for Cross-regional Coordination of Transmission Operators (OCCTO) and token holders (report creation). Information from the marketplace 12 can be obtained via API. For example, the OCCTO system (cross-regional operation organization system 16) can obtain reports such as planned values ​​via API. This linkage makes it possible to automate the creation and linkage of notification data and report data required by self-consignment regulations. In addition, retailers 17 can also buy and sell tokens on the marketplace 12, just like consumers 10. This allows retailers 17 to offer self-consignment electricity procurement using tokens as a menu for customers, and can also use it as a means of retailers' own electricity procurement. Using APIs makes it possible to link with systems used by retailers.In addition, electricity supply and demand service providers 18 can also buy and sell tokens on the marketplace 12, just like consumers 10. This allows the service providers 18 to utilize token buying and selling as part of their electricity service menu, such as peak shaving, for customers. By using an API, it is possible to link with the system used by the service providers 18.

[0027] <System Overview> FIG. 6 is a diagram showing an example of the overall configuration of an electricity procurement system. The electricity procurement system of this embodiment is configured to include a management server 2. The management server 2 is communicatively connected to a user terminal 1 via a communication network 3. The communication network 3 is, for example, the Internet, and is constructed using a public telephone line network, a mobile phone line network, a wireless communication path, Ethernet (registered trademark), etc. The management server 2 is also connected to a blockchain network (hereinafter referred to as blockchain 4). The blockchain 4 is configured from multiple computers (nodes) and manages a distributed ledger.

[0028] The user terminal 1 is a computer operated by the consumer 10, and can be, for example, a smartphone, tablet computer, or personal computer. The cross-regional operation system 16 can also be included in the user terminal 1. The systems of the retailer 17 and the retailer service provider 18 can also be included in the user terminal 1. The consumer 10 (OCCTO, the retailer 17, the service provider 18) can access the management server 2 using the user terminal 1.

[0029] The management server 2 is a computer that realizes the marketplace 12. The management server 2 may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing.

[0030] <Administration Server 2> FIG. 7 is a diagram illustrating an example of the hardware configuration of the management server 2. Note that the illustrated configuration is an example, and other configurations may also be used. The management server 2 includes a CPU 201, a memory 202, a storage device 203, a communication interface 204, an input device 205, and an output device 206. The storage device 203 stores various data and programs, and is, for example, a hard disk drive, a solid state drive, or a flash memory. The communication interface 204 is an interface for connecting to the communication network 3, and is, for example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone network, a wireless communication device for wireless communication, a USB (Universal Serial Bus) connector or an RS232C connector for serial communication, etc. The input device 205 is used to input data, and is, for example, a keyboard, a mouse, a touch panel, a button, a microphone, etc. The output device 206 is used to output data, and is, for example, a display, a printer, a speaker, etc. Each functional unit of the management server 2 described below is realized by the CPU 201 reading a program stored in the storage device 203 into the memory 202 and executing it, and each storage unit of the management server 2 is realized as part of the storage area provided by the memory 202 and the storage device 203.

[0031] 8 is a diagram illustrating an example of the software configuration of the management server 2. The management server 2 includes an asset registration unit 211, a token issuance unit 212, a demand amount input unit 213, a sales amount input unit 214, a matching processing unit 215, a sales processing unit 216, a token transfer unit 217, a power generation prediction acquisition unit 218, a power generation performance acquisition unit 219, a report creation unit 220, an API processing unit 221, and an asset information storage unit 231.

[0032] The asset information storage unit 231 stores information about the power generation equipment 13 (hereinafter referred to as asset information) for each of the power generation equipment 13. The asset information may include, for example, the type, output, and installation location of the power generation equipment 13.

[0033] The asset registration unit 211 registers asset information in the asset information storage unit 231. The asset registration unit 211 can receive asset information from the user terminal 1 of the facility provider 15 and write the received asset information to the asset information storage unit 231. The asset registration unit 211 can also register information (hereinafter, owner information) about the owner of the power generation facility 13 (initially the facility provider 15). In this embodiment, the owner information is managed in a ledger in the blockchain 4, and the asset registration unit 211 can issue a transaction to the blockchain 4 to register the owner information.

[0034] The token issuing unit 212 issues tokens in the blockchain 4, backed by the power generation facility 13 and representing the ownership and offtake rights of the power generation facility 13. The tokens are issued using a technology commonly used in STOs (Security Token Offerings), and a detailed description thereof will be omitted. The token issuing unit 212 can issue any number of tokens. In the examples of FIGS. 3 and 4, 100 tokens are issued for one power generation facility 13, but this is not limited to this, and any number of tokens can be issued, such as 10 tokens or 2,000 tokens. The issued tokens are placed in the wallet of the owner of the power generation facility 13 (facility provider 15).

[0035] The demand amount input unit 213 receives from the consumer 10 the demand amount of electricity desired to be procured from the power generation facility 13. For example, the demand amount input unit 213 can set the demand amount in a purchase request for obtaining the classification 133 of the power generation facility 13 and receive the request from the user terminal 1 of the consumer 10. The demand amount input unit 213 may receive, along with the demand amount, specification of conditions for the power generation facility. The purchase request may specify the power generation type of the power generation facility 13 (solar power generation, wind power generation, etc.), the demand amount (the amount of power desired to be procured), and the time period. The purchase request may include information identifying an individual power generation facility 13, information identifying a specific power plant, or a designation of the area where the power generation facility 13 is located. The purchase request may also include a limit price for the desired purchase amount. Multiple conditions may also be set, and the priorities of the conditions may be set.

[0036] The selling amount input unit 214 receives a designation of tokens to be sold from a seller (the facility provider 15 or the consumer 10) who wishes to sell tokens. The selling amount input unit 214 can receive a selling request, for example, from the seller's user terminal 1. The selling request can set the tokens to be sold and their selling price. A minimum price can be set as the selling price. A range from the minimum price to the maximum price can also be specified as the selling price.

[0037] The matching processing unit 215 can match sell requests with buy requests. The matching processing unit 215 can search for asset information that matches the conditions specified in the buy request. Furthermore, the matching processing unit 215 can identify sell requests for tokens backed by the power generation facilities 13 indicated by the matched asset information, and allocate the tokens related to the identified sell requests to the purchasers. The matching processing unit 215 can allocate sell requests according to the conditions of the received buy requests, for example, in the order in which the buy requests are received. Furthermore, the matching processing unit 215 can also allocate buy requests and sell requests received within a certain period of time together. The matching processing unit 215 can perform matching processing similar to sales processing in the stock market, for example.

[0038] The sales processing unit 216 performs processing related to the sale of tokens to consumers 10. The sales processing unit 216 can accept payments from purchasers of tokens and perform processing to pay the seller. The sales processing unit 216 may make a payment to the seller by subtracting a commission from the amount paid by the purchaser.

[0039] The token transfer unit 217 transfers the amount of tokens corresponding to the share of the power generation facility 13 being sold to the consumer's wallet. The token transfer is automatically carried out by a program on the blockchain when the actual date and time reaches the date and time of each slot (e.g., every 30 minutes). The token transfer unit 217 can issue a transaction to the blockchain 4 to transfer the sold tokens from the seller's wallet to the purchaser's wallet. This allows the token transfer unit 217 to transfer the amount of tokens corresponding to the demand of the consumer 10 to the consumer's wallet.

[0040] The power generation prediction acquisition unit 218 acquires a predicted value of the amount of power to be generated by the power generation facility 13. The power generation prediction acquisition unit 218 may predict the amount of power to be generated by itself, or may acquire the predicted value from an external computer that has predicted the amount of power to be generated. The power generation prediction acquisition unit 218 may, for example, predict the amount of solar radiation for the power generation facility 13 related to solar power generation. The power generation prediction acquisition unit 218 may receive the predicted value of the amount of power to be generated from the user terminal 1 of the owner or provider 15 of the power generation facility 13.

[0041] The power generation result acquisition unit 219 can acquire the result value of the amount of power generated by the power generation facility 13 from the smart meter 14 provided in the power generation facility 13 .

[0042] The report creation unit 220 can output a report regarding the power generation plan. The report creation unit 220 can divide the predicted value of the amount of power to be generated by the power generation facility 13 according to the total amount of tokens (hereinafter referred to as the amount of tokens to be held) of the amount of tokens held in the wallet of the consumer 10 and the amount of tokens to be matched and scheduled to be transferred in a future slot, and include the divided predicted value of the amount of power to be generated in the power generation plan for each consumer 10. The report creation unit 220 can also output a report regarding the actual power generation results. The report creation unit 220 can divide the actual value acquired from the smart meter 14 proportionally according to the amount of tokens to be held by the consumer 10, and include the prorated amount of power to be generated (divided actual power generation value) in the actual power generation results. The report creation unit 220 may include the predicted value predicted in the power generation plan in the actual power generation results.

[0043] The report creation unit 220 can provide a GUI (viewing screen) that enables equipment providers 15, purchasers, and sellers of the power generation equipment 13 to view information (asset information) related to the power generation equipment 13 they own. The viewing screen can include a predicted value for the amount of power generation, the ownership ratio of the power generation equipment 13, basic information about the power generation equipment 13, and the like.

[0044] The report creation unit 220 can create a plan for the Organization for Cross-regional Coordination of Transmission Operators (OCCTO). The report creation unit 220 can also automatically submit the plan to the cross-regional core system 16. The report creation unit 220 can create a ledger that describes information required when the owner or operator of the power generation facility 13 interconnects with the grid, based on asset information, predicted values ​​of power generation amount, actual values ​​of power generation amount acquired from the smart meter 14, etc.

[0045] The API processing unit 221 can provide an API to an external device of the management server 2. The API can be, for example, REST, and the API processing unit 221 can extract and provide necessary information from the information managed by the management server 2 and the blockchain 4 in response to a request from the external device. Using the API, the management server 2 can perform data linkage with the cross-regional operation system 16. The API processing unit 221 can create additional forms or perform system linkage for documents to be submitted to retailers and general electricity transmission and distribution companies based on the data managed by the management server 2 and the blockchain 4. In addition, a mechanism can be provided via the API that allows retailers and companies that provide services to consumers to link and trade terms of purchase and sale via their own systems.

[0046] <Operation> FIG. 9 is a diagram showing the flow of power transmission processing in the power procurement system of this embodiment.

[0047] The management server 2 receives asset information of the power generation facility 13 and records it in the asset information storage unit 231 (S301). The asset information may include the type of power generation facility 13, its output, installation location, etc. The management server 2 issues a token backed by the power generation facility 13 (STO) (S302). After issuing the token, the management server 2 can solicit applicants to become compartmentalized owners of the power generation facility 13. By holding the token, the electricity consumer 10 will have compartmentalized ownership of the power generation facility 13 and the right to offtake the amount of electricity (kWh) generated by that power generation facility 13.

[0048] The management server 2 can record the owner information of the token holder (initially the facility provider 15) in the ledger of the blockchain 4 (S303). The management server 2 can acquire the amount of electricity generated by the power generation facility 13 from a measuring device such as a smart meter 14, and can tally up the amount of electricity generated (kWh) over a certain reference time period, such as a 30-minute value (the measurement time can be set arbitrarily) (S304). The management server 2 allocates the amount of electricity generated to the condominium owners according to the amount of tokens they hold (including matched tokens scheduled to be transferred in future slots) (S305), and can have them supply electricity in the form of self-consignment (S306).

[0049] The management server 2 provides a trading platform that allows users to buy and sell tokens they hold. The management server 2 also provides a trading platform that allows buying and selling as far in advance as possible from the day before power generation (day-ahead market) until the day before power generation. Figure 10 is a diagram showing the flow of distribution of shares in power generation facilities in the power procurement system of this embodiment.

[0050] The management server 2 calculates the offtake amount of power generation (kWh) of the consumer 10 according to the holding ratio of tokens (including matched tokens scheduled for transfer in future slots) (S321). The management server 2 receives a purchase request from the purchaser with set conditions (S322). As described above, the purchase request can set the type of power generation (solar, wind, etc.), amount of power, price, time period, region, superiority or inferiority of the conditions, etc. In addition to this, conditions similar to those of stock trading platforms (limit order, stop order, conditional buy / sell when a certain price is reached, etc.) can also be set.

[0051] The management server 2 accepts the selling request (S323) and matches the token specified in the selling request with the purchasing request based on the conditions set in the purchasing request (S324).

[0052] In the matching process, conditions can be set for buyers and sellers in a detailed manner to suit the actual electricity trading situation. For example, without setting a sales price (or setting a range or letting the price be unspecified), selling or purchasing can be continued until a certain amount of electricity (kWh) is reached from a power generation facility 13 that meets specified conditions (such as solar power). A region can also be specified in the purchase request, and purchasing can be continued from one or more power generation facilities 13 installed in the specified region until a certain amount of electricity (kWh) or the total purchase price reaches a certain amount. It is also possible to specify only the purchase price and continue purchasing or selling without specifying the amount of electricity (kWh). It is also possible to specify only a time period in the purchase request, and continue selling or purchasing until a certain amount of electricity (kWh) is reached within the specified time period. Note that conditions do not need to be set, or priorities can be assigned to the conditions.

[0053] If the sale fails (S325:), the management server 2 does not transfer the tokens from the seller (thus, the ownership and offtake rights are not transferred), and the electricity from the power generation facility 13 can be sold to the wholesale electricity exchange (S326). Note that the electricity may be sold to a retailer in a bilateral transaction rather than on the wholesale market.

[0054] Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and equivalents thereof are also included in the present invention.

[0055] For example, in this embodiment, the location of ownership and offtake rights of the power generation facility 13 is managed using tokens issued by the blockchain 4, but it is not necessary to use blockchain technology. For example, the ownership and offtake rights can be managed in a database, and the administrator of the database (the operator of the management server 2) can guarantee the authenticity of the contents.

[0056] In addition, in this embodiment, owner information regarding the owner of the power generation facility 13 is managed in a ledger of the blockchain 4, but the management server 2 may also be provided with an owner information storage unit that stores owner information.
