[0010] Hereinafter, a power procurement system according to one embodiment 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] Figure 1 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.

[0023] FIG. 2 is a diagram illustrating the distribution of generated power. In the example of FIG. 2, 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 tokens out of 100 tokens and Company B holds 10 tokens out of 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.

[0024] <System Overview> FIG. 3 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.

[0025] 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.

[0026] 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.

[0027] <Administration Server 2> FIG. 4 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.

[0028] 5 is a diagram showing 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.

[0029] 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.

[0030] 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.

[0031] The token issuing unit 212 issues tokens in the blockchain 4, which are backed by the power generation facility 13 and represent 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 example of FIG. 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 2000 tokens. The issued tokens are placed in the wallet of the owner of the power generation facility 13 (facility provider 15).

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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 .

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] The electricity procurement system will be described below. The electricity retailer 19 retains legal ownership of the power generation facility 13, and sells virtual shares of the power generation facility 13 as electronic tokens to the consumers 10, who are the customers of the retailer 19. It is assumed that the consumers 10 procure all of their electricity from the retailer 19. The retailer 19 collects funds to purchase tokens from the consumers 10 and purchases the power generation facility 13 with the collected funds. When the consumer 10 receives an electricity bill from the retailer 19, the amount of electricity (kWh) purchased from the retailer 19 is netted with the amount of electricity (kWh) generated by the power generation facility 13 linked to the purchased token, and the consumer 10 can make payment (or receive payment).

[0044] The investment funds for the power generation facility 13 owned by the retailer 19 are covered by the funds paid by the consumer 10 who purchased the tokens. This allows the consumer 10 to virtually own the power generation facility 13, and the retailer 19 performs net metering of the amount of electricity purchased by the consumer 10 and the amount of electricity generated by the power generation facility 13 in return for the virtual ownership.

[0045] By virtually dividing up the power generation facility 13, it becomes possible for the consumer 10 to virtually own it for a small amount (realized by net metering), and since it is virtually divided up, it becomes possible to divide up and own even power generation facility 13 other than solar power generation, which has physical restrictions on division.

[0046] The amount of power generated by the power generation facility 13 is measured, and the amount of power (kWh) can be supplied in the form of net metering according to the proportion held for each fixed time period (every 30 minutes, for example).

[0047] In addition, by electronically recording the ownership percentage, it is easier to buy and sell, and by providing a platform 12 where ownership and the offtake rights for the associated electricity (kWh) can be bought and sold, the liquidity of assets is increased, and at the same time, by placing existing equipment on the platform 12, the operating rate of the equipment can be improved.

[0048] The retailer 19 enjoys the contract retention effect of retaining the consumers 10 who are attracted to holding tokens as customers for a certain period of time.

[0049] While retailers 19 hold a portion of the ownership of the power generation facilities 13 in the form of tokens, the original funds come from consumers. Electricity (kWh) generated by the power generation facilities 13 can be supplied to consumers 10 in the form of net metering. This system reduces initial investment costs and provides liquidity to the virtual ownership of power generation facilities 13, making it possible to popularize renewable energy power generation facilities 13. In addition, a secondary market (buying and selling) can be created for both new and existing idle facilities, making it easier to sell assets, increasing the value of power generation facilities 13 and improving the utilization rate of idle facilities, which is expected to lead to more efficient operation of Japan's power infrastructure. Ease of entry can be increased by automating as much as possible the process from setting up power generation facilities 13 to trading and reporting.

[0050] FIG. 6 is a diagram illustrating the token purchasing process. The retailer 19 collects funds from the consumer 10 to purchase tokens for the power generation facility 13 and acquires all or part of the compartmentalized ownership. The retailer 19 sells these tokens to the consumer 10. The retailer 19 continues to hold ownership of the power generation facility 13, but sells offtake rights to the consumer 10. Tokens representing these offtake rights are sold by the retailer 19 to the consumer 10. The tokens sold here may be configured so that the retailer 19 resells the purchased tokens while establishing rules that only retain ownership rights under the contract, or the retailer 19 may issue new tokens representing the offtake rights (STO).

[0051] In the example of Figure 6, if a retailer 19 purchases 100 tokens for a 100kW power generation facility 13 and a consumer 10 (household X) purchases 2 tokens, household X will have acquired an offtake right of 2kW.

[0052] FIG. 7 is a diagram illustrating the process of billing electricity charges. In the example of FIG. 7, the amount of electricity used by the consumer 10 (household X) in one month is 450 kWh, and the amount of electricity generated by the power generation facility 13 in one month is 10,000 kWh. The consumer 10 (household X) owns two tokens out of the 100 tokens acquired by the retailer 19, and therefore has an offtake right of 10,000 kWh × 2 / 100 = 200 kWh. Therefore, the retailer 19 can bill the consumer 10 (household X) for 250 kWh, which is calculated by subtracting 200 kWh from 450 kWh through net metering.

[0053] FIG. 8 is a diagram showing the flow of the power transmission process.

[0054] The management server 2 receives asset information of the power generation facility 13 and records it in the asset information storage unit 231 (S301), and issues a token backed by the power generation facility 13 (STO) (S302). Here, the retailer 19 can solicit those (consumers 10) who wish to become pseudo-owners of the power generation facility 13. The retailer 19 purchases tokens using the collected funds (S401). In the examples of FIGS. 6 and 7, the retailer 19 purchases tokens corresponding to 100% of the equity of a certain power generation facility 13. The management server 2 records the owner information of the retailer 19 who will be the holder of the token in the ledger of the blockchain 4 (S303).

[0055] The retailer 19 sells the tokens to the consumer 10 (S402). A rule is established in which the consumer 10, by holding the tokens, has the right to offtake the amount of electricity (kWh) generated from the power generation facility 13 that the consumer 10 virtually owns via the retailer 19.

[0056] The management server 2 acquires the amount of electricity generated by the power generation facility 13 from measuring devices such as the smart meter 14, and can tally up the amount of electricity generated (kWh) for a certain reference time period, such as a 30-minute value (the measurement time period can be set arbitrarily) (S304). The management server 2 can allocate the amount of electricity generated to the condominium owners according to the number of tokens they hold (S305). In the examples of Figures 6 and 7, all of the amount of electricity generated is allocated to the retailer 19.

[0057] Retailer 19 supplies the amount of electricity (kWh) to consumer 10 in the form of net metering (S403). Specifically, although consumer 10 does not legally own power generation facility 13, an intermediary electricity sales company such as retailer 19 owns power generation facility 13 in a virtual division, and retailer 19 bills consumer 10 in the form of net metering for the amount of electricity (kWh) generated from the electricity sold by retailer 19 and the token purchase amount (which is pseudo and does not include ownership, but only offtake rights) applied for by the customer through retailer 19. For example, if consumer 10 purchases 400 kWh from retailer 19 and procures 100 kWh from power generation facility 13 via retailer 19, the amount billed by retailer 19 to consumer 10 will be an amount equivalent to 400 - 100 = 300 kWh.

[0058] 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.

[0059] 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.
