[0019] Hereinafter, an embodiment of the power procurement system of the present disclosure will be described.

[0020] In the power procurement system of this embodiment, power generation facilities are subdivided using security tokens (security tokens), enabling compartmentalized ownership. This allows the power procurement system of this embodiment to reduce the initial investment required to own the power generation facilities. In the power procurement system of this embodiment, the power generation facilities may be, for example, solar panels. However, in the power procurement system of this embodiment, the power generation facilities are not limited to solar panels, and may also be thermal power generation facilities, storage batteries, etc. In this disclosure, security tokens (security tokens) are also referred to as "ST." Furthermore, the power procurement system of this embodiment realizes a marketplace that enables high-frequency trading, where ST is held only when in use. This, for example, can eliminate idle power generation facilities and increase the value of the power generation facilities by pricing the power generation facilities in the secondary market and ensuring liquidity. 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.

[0021] Generally, private power generation facilities are owned by a single business or individual, etc. In this embodiment, a model is adopted in which one power generation facility can be jointly owned by multiple consumers (demand users).

[0022] Conventional large-scale power generation facilities (not only solar, but also thermal and wind power) require high initial investment costs, making their ownership a significant burden for a single business. Furthermore, some facilities are only used for daytime peak shaving and are 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 the business with no choice but to sell the power 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 a 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, creating 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.

[0023] Therefore, in the electricity procurement system of this embodiment, the power generation facility is divided virtually, not physically, and the divided sections are represented, for example, by ST of a blockchain, allowing users of the power generation facility to hold ownership of each divided unit. This makes it possible to own a portion of expensive power generation facility for a small amount, and because the facility is divided virtually, it is also possible to own power generation facility other than solar power generation, which has physical restrictions on division, in divided units.

[0024] 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).

[0025] Furthermore, the power procurement system of this embodiment can electronically record the percentage of power generation facilities owned. This allows the power procurement system of this embodiment to increase ease of buying and selling. Therefore, the power procurement system of this embodiment is expected to increase asset liquidity by providing a platform where ownership rights and the offtake rights for the associated amount of electricity (kWh) can be bought and sold. Furthermore, the power procurement system of this embodiment can also include existing facilities on the platform, making it possible to improve the facility operating rate.

[0026] In the electricity procurement system of this embodiment, the offtake rights may be represented by, for example, a utility token. Here, a utility token refers to a token that represents a secondary asset or value generated from a certain asset or value. For example, a utility token may be a token that represents value generated from a security token. Furthermore, a utility token may be, for example, a type of token that does not have monetary value itself and only acquires asset value when exchanged for another specific asset. In the electricity procurement system of this embodiment, the utility token can be used to indicate the relationship between the offtake rights corresponding to the amount of generated electricity and the amount of electricity used during the transaction. In this disclosure, the utility token is also referred to as "UT." In addition, in this disclosure, at least one of ST (security token) and UT (utility token) may be simply referred to as "token."

[0027] When solar power generation assets are jointly owned or when self-consignment of electricity is performed using such assets, it is assumed that the amount of electricity generated must be appropriately distributed according to the ownership stake of the assets. Here, it is considered effective to use a blockchain system, which is considered highly tamper-resistant, as a means of proving ownership and recording the amount of electricity generated associated with each owner. For example, in the electricity procurement system of this embodiment, a smart contract may be constructed that transfers UTs according to the amount of ST held. Here, a smart contract refers to a computer protocol intended to automate contracts or smoothly verify, enforce, execute, and negotiate contracts. For example, a smart contract may be implemented in an application running on a blockchain. A smart contract has the advantage of being able to process transactions with guaranteed credit without the intervention of a third party. The electricity procurement system of this embodiment not only realizes direct financing (Security Token Offering: STO) but also enables the protection of the rights of investors (e.g., solar panel owners) (appropriate distribution of electricity generated) and the assurance of liquidity (easy asset transfer).

[0028] For example, parties who jointly invest in a power generation facility such as solar panels can each hold ST equivalent to their investment. For example, let's say the entire power generation facility, such as solar panels, is worth 40 ST. In this case, party A, who invested 50% of the power generation facility, may hold 20 ST in accordance with their investment. Party B, who invested 12.5% ​​of the power generation facility, may hold 5 ST in accordance with their investment. Party C, who invested 37.5% of the power generation facility, may hold 15 ST in accordance with their investment. Hereinafter, security tokens (ST) may be referred to as units of tokens, such as the above-mentioned 20 ST, 5 ST, 15 ST, etc.

[0029] Meanwhile, suppose the power generation facility is scheduled to generate 80 kWh of power for 30 minutes on a given day. In this case, the above-mentioned party A may hold, for example, 40 UT as the right to receive 50% of the 80 kWh. Furthermore, for example, the above-mentioned party B may hold, for example, 10 UT as the right to receive 12.5% ​​of the 80 kWh. Furthermore, for example, the above-mentioned party C may hold, for example, 30 UT as the right to receive 37.5% of the 80 kWh. In this way, UT may be allocated according to the stake of the ST. Hereinafter, utility tokens (UT) may be referred to as the unit of token, such as the above-mentioned 40 UT, 10 UT, 30 UT, etc.

[0030] By adopting ST, a blockchain security token, transactions are completed by transferring ST between wallets. This makes it easier to sell assets, which is expected to create a secondary market. In addition, by adopting UT, a token that represents the amount of electricity (to be acquired), it is possible to not only respond to appropriate distribution of power generation and output suppression, but also to confirm the consistency of wheeling charges.

[0031] 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.

[0032] 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 improves asset value.

[0033] 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 (ST) using tokens with offtake rights (UT) for electricity (kWh). Therefore, there are no restrictions on the power generation facilities that can be jointly owned, and it can be applied to all power generation methods, including thermal, hydroelectric, wind, geothermal, biomass, and nuclear power, as well as storage batteries.

[0034] Furthermore, the power procurement system of this embodiment can also temporarily sell unused power generation facilities, such as those used only during certain seasons or times at factories. Therefore, even if there are periods when the power load is not in operation, the power generation facilities can be operated continuously and profits can be earned. This is expected to improve the utilization rate of the facilities, and as a secondary effect, it can reduce the operational costs of power generation for an entire country, such as Japan, and / or improve the economic viability of owning power generation facilities. (Since this system can be used by consumers who need short-term power procurement, such as those requiring peak shaving, regardless of the magnitude of demand, it may be possible to sell power at a higher price than selling it to a regular power company.)

[0035] In addition, by virtually dividing and owning the power generation facility, unfairness among owners due to differences in the amount of power generated due to the deterioration of each panel and / or differences in the amount of solar radiation does not occur. This eliminates unfairness caused by fluctuations (differences) in the amount of power generated between solar panels, as in the case of conventional community solar systems.

[0036] <Outline of electricity procurement> FIG. 1 is a diagram illustrating an overview of power procurement in one embodiment. A consumer 10 (company A) owns a demand facility 11 and procures power for use at the demand facility 11 by purchasing a virtual division 131 of a power generation facility 13 from a marketplace 12. Here, division 131 may be the virtual ownership division of the STO described above. The power generated by the power generation facility 13 is divided according to the share (ST) 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 location located elsewhere by 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. In this way, power can be supplied by self-dispatch. The existence of the marketplace 12 ensures the liquidity of the power generation facilities 13 (classifications thereof). This allows the consumer 10 to acquire the necessary percentage of shares when necessary and perform self-consignment from the private power generation facilities 13. That is, in this embodiment, the consumer 10 owns the power generation facilities 13 only when using the facilities, and can procure the amount of electricity only when using the facilities.

[0037] For reference, Figure 2 is a diagram explaining a conventional form of joint ownership of solar panels. Conventionally, when trying to jointly own solar panels, the reality was that the condominium owners owned the power generation facility 13 (solar panels) in physically divided units (for example, 1 / 3). In this case, for example, for one power generation facility 13, a smart meter 14 was installed for each physical section 131, and the amount of power generated by each section 131 was managed.

[0038] FIG. 3 is a diagram illustrating a joint ownership structure of the power generation facility 13 according to this embodiment. That is, FIG. 3 is a diagram illustrating an example of an STO using solar panels. In this embodiment, the power generation facility 13 itself may be, for example, a solar panel similar to that used in conventional community solar power generation. In the example of FIG. 3, only one smart meter 14 is installed in the power generation facility 13. This single smart meter 14 measures the amount of power generated by the entire power generation facility 13. Here, it is assumed that 100 tokens are issued by ST for the power generation facility 13. The power generation facility 13 is jointly owned by four companies, Company A, Company B, Company C, and Company D, with respective ownership interests of 60%, 10%, 20%, and 10%. In this case, Company A holds 60 tokens, Company B holds 10 tokens, Company C holds 20 tokens, and Company D holds 10 tokens, and they can prove their ownership ratios (ST). According to this ratio, the amount of electricity generated by the power generation facility 13 (measured by the smart meter 14) is also divided (UT) and deemed to have been self-consigned to each company. In this way, in this embodiment, facilities can be owned according to the ratio of ST, and offtake rights (UT) for the amount of electricity (kWh) generated from the facilities can be held. Here, suppose that in another time slot, Company A sells 30 tokens, Company B purchases an additional 30 tokens, Company C sells 10 tokens, and Company E purchases 10 tokens. In this case, too, the amount of electricity generated by the power generation facility 13 can be virtually divided (UT) and deemed to have been self-consigned to each company according to the token holding ratio. In this way, by enabling the buying and selling of electricity within a measured unit time (time slot), liquidity can be created in the market. Note that the amount of electricity can be measured and allocated for each time slot of a predetermined length (e.g., 30 minutes). Note that the length of the time slot can be set to any length that varies depending on the market.

[0039] FIG. 4 is a diagram illustrating the distribution of generated power. In the example of FIG. 4, the time transition of the amount of power generated from the power generation facility 13 is shown by a curve 141. Assume that the power generation facility 13 generates 30 kWh at 12:00 (a 30-minute time period), and Company A holds 60 of the 100 tokens, and Company B holds 10 of the 100 tokens. In this case, 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 kW × 10 / 100 = 3 kWh. Similarly, assume that 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. In this case, 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.

[0040] FIG. 5 is a diagram illustrating an overview of transactions in the electricity procurement system of this embodiment. In the marketplace 12 (trading platform (trading PF)), an equipment provider 15 (which may also be the equipment owner) registers information about the power generation equipment 13 and issues tokens (asset registration). Then, a consumer 10, who will be the token seller, registers the conditions under which he or she wishes to sell the equipment. Furthermore, a consumer 10, who will be the token buyer, sets conditions (such as the power generation type (solar or wind, etc.), amount of power, price, time period, and / or region) of the power generation equipment 13 he or she wishes to purchase (the superiority or inferiority of the conditions can also be set). In this way, matching 121 of the power generation equipment 13's division 131 is performed in the marketplace 12. Matching is performed every 30 minutes from now (the current unit of power measurement time; if the unit of time changes, it is based on the new specified unit of time) (reservation of purchase and sale). Then, when the actual date reaches the time of the slot, the ownership of the power generation equipment 13's division 131, i.e., ST (and offtake right, i.e., UT), is transferred from the seller to the buyer. With this transfer, an amount of tokens corresponding to the ownership percentage of division 131 will be transferred to the wallet of the purchaser's consumer 10. This will prove the transfer of ownership (and offtake rights).

[0041] The marketplace 12 can also automatically calculate the amount of electricity (kWh) to be offtaken (UT) according to the amount of electricity generated (forecast and / or actual value) and the token holding percentage (ST). In addition, the marketplace 12 can record the amount of electricity generated (power generation forecast and actual results) and create a report for the Organization for Cross-regional Coordination of Transmission Operators (OCCTO) and / or token holders (report creation).

[0042] Information from the marketplace 12 can be obtained via an API (Application Programming Interface). For example, the OCCTO system (cross-regional operation system 16) can obtain reports such as planned values ​​via the API. This data integration can automate integration, such as the creation of notification data and / or report data required by self-consignment regulations. Similarly to the consumer 10, the retailer 17 can also buy and sell tokens on the marketplace 12. This allows the retailer 17 to offer power procurement using tokens as a menu for customers and to utilize them as the retailer's own power procurement method. In this way, power procurement through self-consignment using tokens may also be provided. Using the API allows integration with the system used by the retailer 17. Similarly to the consumer 10, the power supply and demand service provider 18 can also buy and sell tokens on the marketplace 12. This allows the power supply and demand service provider 18 to utilize token buying and selling as part of a power service menu for customers, such as peak shaving. The above-mentioned API can also be integrated with the system used by the power supply and demand service company 18.

[0043] <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 may be constructed using a public telephone network, a mobile phone network, a wireless communication path, Ethernet (registered trademark), or the like. 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.

[0044] The user terminal 1 is a computer operated by the consumer 10, and may be, for example, a smartphone, a tablet computer, or a personal computer. Here, the cross-regional operation system 16 may also be included in the user terminal 1. The systems of the retailer 17 and / or the retailer service provider 18 may also be included in the user terminal 1. The consumer 10 (OCCTO, the retailer 17, or the electricity supply and demand service provider 18) can access the management server 2 using the user terminal 1.

[0045] 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.

[0046] The blockchain 4 may be based on database technology for recording information. In this embodiment, the blockchain 4 may manage data in units called blocks, similar to general blockchains, and store data by linking these blocks like a chain. Each block in the blockchain contains data called a hash value, which represents the contents of the previous block. If data is tampered with, the resulting hash value will also be different. For this reason, the hash values ​​of all subsequent blocks must be changed. However, this is extremely difficult, and tampering with data managed by a blockchain is considered difficult. A blockchain manages the same data in multiple locations. For this reason, a blockchain is also called a distributed ledger. Blockchains can be used for general purposes, and many applications have been devised, including smart contracts that automate contracts and transactions.

[0047] In the electricity procurement system of this embodiment, the blockchain 4 may be based on the same technology as the general blockchain described above. However, in one embodiment, the blockchain 4 may be based on database technology instead of the general blockchain technology.

[0048] <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 some of the illustrated configuration may be omitted, or the management server 2 may have a configuration other than that illustrated. 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 / or programs. The storage device 203 may be, 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. The communication interface 204 may be, 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, or the like. The input device 205 is a device used to input data. The input device 205 may be, for example, a keyboard, a mouse, a touch panel, buttons, or a microphone.

[0049] The input device 205 accepts input of commands for each functional unit of the management server 2, which will be described later. The output device 206 is a device used when outputting data. The output device 206 may be, for example, a display, a printer, or a speaker. Each functional unit of the management server 2, which will be described later, may be realized by the CPU 201 reading a program stored in the storage device 203 into the memory 202 and executing it. The CPU 201 may interpret commands input to the input device 205 for each functional unit of the management server 2, which will be described later. The CPU 201 may create information to be displayed on the output device 206 and control the output device 206 to issue a command to the output device 206 to display the information on the output device 206. Furthermore, each storage unit of the management server 2 may be realized as part of the storage area provided by the memory 202 and the storage device 203.

[0050] The input device 205 and the output device 206 may each be singular or plural. Furthermore, the input device 205 and the output device 206 may be integrated into one device, such as a touch panel. Furthermore, while the management server 2 has been described as including the input device 205 and the output device 206, this is not limiting. For example, the management server 2 may not include the input device 205 and the output device 206. Furthermore, the management server 2 may include the input device 205 and the output device 206, and an external input device 205 and an external output device 206 may also exist. If the input device 205 and the output device 206 are external to the management server 2, the management server 2 may exchange various commands and information with the external input device 205 and the output device 206 via the communication interface 204. Specifically, the external input device 205 may receive commands for each functional unit of the management server 2, which will be described later. In this case, the management server 2 may receive these commands via the communication interface 204. The command received in this manner may be interpreted by the CPU 201. Alternatively, the CPU 201 may create information to be output by the external output device 206, and transmit the command to be output by the external output device 206 to the external output device 206 via the communication interface 204.

[0051] 8 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, and a matching processing unit 215. The management server 2 also includes 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.

[0052] 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 / or installation location of the power generation equipment 13.

[0053] 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 may be managed in a ledger of the blockchain 4. The asset registration unit 211 can issue a transaction to the blockchain 4 to register the owner information.

[0054] The token issuing unit 212 issues tokens (ST and UT) that are backed by the power generation facility 13 and represent the ownership and offtake rights of the power generation facility 13 on the blockchain 4. The issuance of tokens can use technology that is commonly used in STOs, so a detailed explanation 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. However, the token issuing unit 212 may issue any number of tokens, 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).

[0055] The demand amount input unit 213 receives, from the consumer 10, an input of the demand amount of electricity desired to be procured from the power generation facility 13. The demand amount input unit 213 can receive, for example, information from the user terminal 1 of the consumer 10, in which the demand amount is set in a purchase request for obtaining the classification 133 of the power generation facility 13. 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 (e.g., solar power generation or wind power generation), the demand amount (the amount of power desired to be procured), and / or a time period. The purchase request may include information identifying an individual power generation facility 13, information identifying a specific power plant, and / or a designation of the area in which the power generation facility 13 is located. Furthermore, the purchase request may include information on the predicted power generation value of the power generation facility 13 and / or information on the self-consignment destination. The purchase request may also include a desired purchase price as a limit price. Multiple conditions may be set in the purchase request, and the priorities of the conditions may be set.

[0056] 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 from, for example, 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.

[0057] 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 facility 13 indicated by the matched asset information. Furthermore, the matching processing unit 215 can allocate tokens related to the identified sell requests to the purchasers. For example, the matching processing unit 215 can allocate sell requests in the order in which the buy requests are received, according to the conditions of the received buy requests. Furthermore, the matching processing unit 215 can also allocate buy requests and sell requests received within a certain period of time together. For example, the matching processing unit 215 can perform matching processing similar to sales processing in the stock market.

[0058] 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 deduct a commission from the amount paid by the purchaser and make a payment to the seller.

[0059] 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 may be performed automatically by a program on the blockchain when the actual date and time reaches the date and time of each slot (for example, 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.

[0060] 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 also calculate a predicted value of the amount of power to be generated by the power generation facility 13 based on data indicating past performance data of various conditions, such as weather, solar radiation, temperature, and / or humidity. Furthermore, the power generation prediction acquisition unit 218 may calculate a predicted value of the amount of power to be generated by the power generation facility 13 taking into account future output suppression and / or a weather forecast. Here, output suppression refers to a restriction by a power company or the like on the supply of power from a power generation facility, such as a solar power generation facility, to the power grid. For example, output suppression may be output suppression until noon one day before, or may allow for plan changes on the day. The power generation prediction acquisition unit 218 may also change the amount of power generated by the power generation facility 13 depending on whether the power source is subject to output control. The power generation prediction acquisition unit 218 may also change the amount of power generated by the power generation facility 13 depending on whether the area is likely to be subject to output suppression. The power generation prediction acquisition unit 218 may receive a predicted value of the amount of power generated from the user terminal 1 of the owner or provider 15 of the power generation facility 13.

[0061] 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 .

[0062] The report creation unit 220 can output a report regarding the power generation plan. The report creation unit 220 divides 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. Then, the report creation unit 220 can include the predicted value of the amount of power to be generated divided in this way in the power generation plan for each consumer 10. Furthermore, the report creation unit 220 can output a report regarding the actual power generation results. The report creation unit 220 pro rata divides the actual value acquired from the smart meter 14 according to the amount of tokens to be scheduled to be held by the consumer 10. Then, the report creation unit 220 can include the pro rata divided 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.

[0063] The report creation unit 220 can provide a GUI (viewing screen) that enables the equipment provider 15, purchaser, and / or seller of the power generation equipment 13 to view information (asset information) related to the power generation equipment 13 that they own. The viewing screen can include a predicted value of the amount of power generation, the ownership ratio of the power generation equipment 13, and / or basic information about the power generation equipment 13.

[0064] 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 containing 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, and / or actual values ​​of power generation amount obtained from the smart meter 14.

[0065] 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 (REpresentational State Transfer). In response to a request from an external device, the API processing unit 221 can extract necessary information from the information managed by the management server 2 and the blockchain 4 and provide the API. By 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 / or 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 / or companies providing services to consumers to link and trade terms of sale through their own systems.

[0066] <Operation> FIG. 9 is a diagram showing the flow of power transmission processing in the power procurement system of this embodiment.

[0067] The management server 2 receives asset information of the power generation facility 13 and records (registers) the asset information in the asset information storage unit 231 (S301). The asset information may include the type, output, and / or installation location of the power generation facility 13. In step S301, the asset information of the power generation facility may be registered, for example, by the facility owner. Furthermore, when the asset information of the power generation facility is registered, measures may be taken to make it difficult to register by impersonation. For example, a retailer may temporarily purchase tokens corresponding to the asset information of the power generation facility 13.

[0068] Next, the management server 2 issues tokens backed by the power generation facility 13 (S302). In step S302, the management server 2 may issue any number of tokens. However, it is also conceivable that setting an upper limit or standard for the number of tokens to be issued would facilitate trading. Therefore, for example, 100 tokens may be granted per power generation facility 13, with the amount granted representing the ownership percentage of that facility. In this case, the amount of electricity corresponding to the tokens may be calculated and displayed separately. Alternatively, the number of tokens issued may be determined per amount of electricity generated by the power generation facility 13. In particular, when trading electricity across multiple power generation facilities, the number of tokens issued may be determined per amount of electricity generated. For example, the number of tokens to be issued to a power generation facility may be determined by multiplying the number of tokens granted per predetermined unit output (kWh) by the maximum output (kWh) of the power generation facility, which is the facility's capacity. For example, if it is determined that 1 ST is to be issued per 1 kWh and the power generation facility's maximum output is 150 kWh, 150 tokens may be issued. In this case, it is assumed that the tokens issued may differ from the percentage of the equity of the power generation facility 13. A separate allowance may be made for this difference in equity. In the above case, the maximum output may be the rated output, which is the maximum value of the output used under certain conditions.

[0069] The share of the power generation facility 13 may be determined after the amount of power traded is determined. The amount of power generated by the power generation facility 13 may vary depending on past performance, such as the period or time of power generation. In this case, the amount of tokens may also vary according to changes in the amount of power generated by the power generation facility 13. Furthermore, the amount of power that can be obtained in the future may be converted into a present value to enable trading of tokens. For example, the conversion may be such that the further in the future the amount of power that can be obtained is, the more discounted the rate.

[0070] After issuing the token, the management server 2 can solicit applications from those who wish to become owners of the power generation facility 13. By holding the token, the electricity consumer 10 will have ownership of the power generation facility 13 (represented by ST) and the offtake right (represented by UT) for the amount of electricity (kWh) generated by the power generation facility 13.

[0071] The management server 2 can record (register) 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 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 tokens that are scheduled to be matched and transferred in future slots) (S305), and can have them supply electricity in the form of self-consignment (S306).

[0072] The power supply by self-consignment performed in S306 may be performed after creating a self-consignment plan and reporting it to, for example, OCCTO. For example, the management server 2 may automatically calculate the self-consignment planned value and automatically transmit it to OCCTO after matching is completed by the matching processing unit 215. Also, in S306, the management server 2 may be able to supply only the amount of power generation that matches the self-consignment planned value.

[0073] It is assumed that the demand amount of electricity to be procured from the power generation facility 13 will differ depending on the time period during which the electricity is required, and the required power generation capacity of the power generation facility 13 will differ. The demand amount input unit 213 can receive information from the user terminal 1 of the consumer 10, in which the demand amount is set in a purchase request for acquiring the classification 133 of the power generation facility 13. For this reason, the purchase request may also include information specifying the time period, and may also include the predicted amount of electricity to be generated during that time period.

[0074] The management server 2 provides a trading platform that enables users to buy and sell tokens they own. The management server 2 also provides a trading platform that enables buying and selling as far in advance as possible from the day before power generation (day-ahead market) until the day before power generation.

[0075] FIG. 10 is a diagram showing the flow of distribution of shares of power generation facilities in the power procurement system of this embodiment.

[0076] The management server 2 calculates the offtake amount (which may be expressed by UT) of the amount of power generated (kWh) by the consumer 10 according to the holding ratio of ST (including matched tokens scheduled for transfer in future slots) (S321). The management server 2 receives a purchase request from the purchaser, in which conditions are set (S322). As described above, the purchase request can set the type of power generation (such as solar or wind power), amount of power, price, time period, and / or region, as well as the relative merits of the conditions. In addition to this, conditions similar to those of a stock trading platform (such as limit orders, stop orders, or conditional buy / sell when a certain price is reached) can also be set.

[0077] The management server 2 accepts the selling request (S323). Next, the management server 2 matches the tokens specified in the selling request with the purchasing request based on the conditions set in the purchasing request (S324). The matching process performed in step S324 is also referred to as the "matching process."

[0078] The matching process allows for detailed matching between buyers and sellers by adjusting the conditions to match 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. Furthermore, conditions do not need to be set, and priorities can be assigned to the conditions.

[0079] In the matching process performed in step S324, a transaction screen displaying predetermined transaction information may be displayed. In this case, the transaction screen may be displayed on the output device 206 or the like. For example, in the matching process, it may be displayed whether or not the power generation facility is subject to output curtailment. Furthermore, when the matching process is performed, instead of displaying the amount of power generated by the power generation facility, a predicted value of the amount of power generated by the power generation facility may be displayed. Furthermore, in the matching process, for example, an index of the reliability of the predicted amount of power generated by the power generation facility may be displayed. Furthermore, in the matching process, it may be displayed whether or not the minimum output capacity of the power generation facility 13 is guaranteed within the transaction period, and / or the specific value of the minimum output capacity (kWh). Furthermore, in the matching process, it may be displayed specific compensation details if the guaranteed minimum power capacity is actually exceeded.

[0080] Furthermore, if there is a discrepancy between the predicted and actual power generation amounts of the power generation facilities during the matching process, countermeasures may be taken in response to the discrepancy. Furthermore, when such a discrepancy occurs, feedback regarding the discrepancy may be provided to improve the prediction accuracy or lower the reliability index.

[0081] If the sale and purchase fails after the matching process (S325: NO), the management server 2 does not transfer the tokens from the seller (thus, the ownership and offtake rights are not transferred). In this case, the electricity from the power generation facility 13 may be sold to the wholesale electricity exchange (S326). In this case, the electricity may be sold to a retailer in a bilateral transaction rather than on the wholesale market.

[0082] The matching process in this embodiment will be further described below. Here, the matching process in this embodiment may be the process executed in step S324 shown in FIG.

[0083] As described above, the matching processing unit 215 of the management server 2 may perform matching processing similar to sales processing in a normal stock market. When matching a sell request with a buy request, the matching processing unit 215 may perform matching from the perspective of, for example, the (current) amount of electricity and / or the percentage of equity (tokens), price, etc. Specifically, the matching processing unit 215 may perform matching from the following perspectives, for example: (1) Shares (tokens) and price of power generation facility 13 That is, the transaction may be carried out by displaying the percentage of the share (token) of the power generation facility 13 and its price. (2) Amount and price of electricity generated by power generation facility 13 That is, the amount of electricity generated by the power generation facility 13 and its price may be displayed and traded.

[0084] The viewpoint shown in (2) above may be calculated based on, for example, the product of (a) the predicted value of the power generated by the power generation facility 13, (b) the accuracy of the prediction (such as the past accuracy rate), and (c) the price per unit of power. In particular, the accuracy of the prediction (such as the past accuracy rate) in (b) above is not information that has been confirmed as of the present time, so it may be displayed as a future predicted value while trading.

[0085] Furthermore, the (a) predicted value of the power generation power by the power generation facility 13 and the accuracy of the prediction (such as the past accuracy rate) may be determined based on various factors. For example, the management server 2 may evaluate the value of the power generation facility 13 as a power generation facility, and trading may be conducted based on the evaluated value. Furthermore, the management server 2 may display various evaluations on the output device 206 at the time of trading. The value of the power generation facility 13 as a power generation facility may also be evaluated from various perspectives. For example, the value of the power generation facility 13 as a power generation facility may be evaluated from the perspective of how long a period and / or how much output is predicted.

[0086] Furthermore, for example, the value of the power generation facility 13 as a power generation facility may be evaluated from a perspective other than the amount of power (kWh) generated. Specifically, the value of the power generation facility 13 as a power generation facility may be evaluated, for example, based on the amount of CO2 emissions until the power generation facility is completed. Furthermore, the value of the power generation facility 13 as a power generation facility may be evaluated, for example, based on the amount of CO2 emissions per kW of power generated by the power generation facility 13. Furthermore, the value of the power generation facility 13 as a power generation facility may be evaluated, for example, based on the amount of CO2 emissions until the power generation facility is disposed of. Furthermore, the value of the power generation facility 13 as a power generation facility may be displayed on the output device 206 or the like together with the comparison target, or may be displayed ranked, as a criterion for matching.

[0087] Furthermore, the value of the power generation facility 13 as a power generation facility may be evaluated from the perspective of various risks. For example, the value of the power generation facility 13 as a power generation facility may be evaluated based on trends in the frequency and / or severity of natural disasters in the region where the power generation facility is installed. The value of the power generation facility 13 as a power generation facility may also be evaluated based on the security and / or political stability of the region where the power generation facility is installed.

[0088] The value of the power generation facility 13 as a power generation facility may also be evaluated based on the degree to which electricity is consumed in the area where it is generated, i.e., the degree of local production and consumption. The closer the place where electricity is generated and consumed, the less burden there is on infrastructure such as power lines. Furthermore, electricity generated close to the consumption area can provide a sense of security to those who consume the electricity.

[0089] Furthermore, the value of the power generation facility 13 as a power generation facility may be evaluated from the perspective of the power generation facility's past output report, the power generation facility's lifespan, and / or a deterioration prediction of the power generation facility. The value of the power generation facility 13 as a power generation facility may also be evaluated from the perspective of the degree of environmental impact, such as whether fill is used at the installation site of the power generation facility. The value of the power generation facility 13 as a power generation facility may also be evaluated from the perspective of the cleanliness of renewable energy, such as the degree of legality of the power generation facility 13. The value of the power generation facility 13 as a power generation facility may also be evaluated from the perspective of, for example, the reduction of environmental impact, such as an item listed in the Sustainable Development Goals (SDGs). Note that any of the above evaluations may include an evaluation expressed by a specified numerical value based on a predetermined standard. For example, a five-point scale may be used, with each increasing number indicating a higher evaluation. Specifically, a tiered scale may be defined, such as 1 (bad), 2 (slightly bad), 3 (average), 4 (slightly good), and 5 (good), and a numerical value indicating the value of each power generation facility 13 may be included in the evaluation.

[0090] Next, the self-consignment performed in step S306 of FIG. 9 will be further described.

[0091] The power procurement system of this embodiment may be configured to reflect the conditions required for self-consignment. For example, the power procurement system of this embodiment may be configured to prevent transactions (bidding) that exceed the demand amount (maximum received power) that the power supplier can handle. In this way, self-consignment that exceeds the amount that can be consumed is avoided, thereby preventing, for example, a situation in which a penalty is imposed. To implement such a measure, the power procurement system of this embodiment may automatically obtain the contract capacity (maximum received power) of the self-consignment destination.

[0092] When trading is conducted in the power procurement system of this embodiment, a bidder may be prevented from bidding for electricity that exceeds the demand amount handled by the bidder. For example, the trading platform 12 provided in the power procurement system of this embodiment may obtain information related to a consumer's contracted power capacity from an external server such as an electric power utility (electricity retailer). Furthermore, if OCCTO's external server manages information related to a consumer's contracted power capacity, the information may be obtained from OCCTO's external server. Such information related to a consumer's contracted power capacity may be obtained, for example, before participating in a bidding for trading or before a successful bid. Furthermore, such information related to a consumer's contracted power capacity may be obtainable using the consumer's identification information and / or authentication information. Furthermore, such information related to a consumer's contracted power capacity may be obtainable using an API.

[0093] Furthermore, when a transaction is conducted in the power procurement system of this embodiment, various data may be acquired in addition to information related to the consumer's contracted power capacity. For example, trading platform 12 may acquire data related to power consumption for each past 30-minute time slot. Trading platform 12 may also acquire data from the previous day, or data such as the average, minimum, or maximum value for a specified time or period (e.g., weekday, week, month, or year).

[0094] In addition, a consumer participating in a transaction may submit (transmit) information indicating the contract capacity (maximum power receiving capacity) under contract with an electric power utility, along with a predetermined certificate, to an operator such as an external server. Here, the contract capacity indicates the maximum power receiving capacity at the consumer's facility to which the consumer will self-consign power after winning the bid. Trading platform 12 may automatically acquire the submitted (transmitted) information indicating the contract capacity from an external server or the like. At this time, the consumer's identification information and authentication information may be used. At least one of the identification information and authentication information may be issued to the consumer from, for example, an external server. A consumer can participate in a transaction by entering at least the identification information and authentication information into trading platform 12 at the time of the transaction. By using the identification information and authentication information, trading platform 12 can acquire information indicating the contract capacity of the consumer intending to participate in the transaction from the external server. This allows trading platform 12 to restrict consumer bids that correspond to an amount of power that exceeds the maximum power receiving capacity at the consumer's facility to which the consumer will self-consign power. In the trading platform 12, the management server 2 may store this identification information and authentication information in the storage device 203 or the like in association with information indicating the submitted (transmitted) contract capacity or the like.

[0095] Next, examples of screens that can be displayed during the above-described transactions will be further described.

[0096] When conducting a transaction on the trading platform 12, screens such as those shown in FIGS. 11 to 14 may be displayed on the output device 206 of a consumer, facility owner, or operator of the management server 2. Specifically, the CPU 201 creates information related to the screen, and the management server 2 issues a command to the output device 206 to display a screen based on the information on the screen. In FIGS. 11 to 14, a selection screen is shown on the left, and a confirmation screen is shown on the right. Here, the trading platform 12 may have a search function that enables a search to be performed in response to input of various conditions when selecting the ST, UT, and / or power generation facility 13 to be purchased. Furthermore, the trading platform 12 may display the ST, UT, and / or power generation facility 13 that match the search on the selection screen. The input device 205 accepts input of various conditions and input of information and instructions related to the transaction.

[0097] FIG. 11 shows a screen that may be displayed on the output device 206 when the transaction amount has been determined and ST is being traded. By displaying such a screen, the consumer can check the availability of the power generation facility 13, i.e., the slots available for purchasing ST, on the selection screen shown on the left side of FIG. 11. On the selection screen shown on the left side of FIG. 11, a filled-in slot may indicate that there is no availability, and an unfilled slot may indicate that there is availability. When the consumer selects an available slot on the selection screen shown on the left side of FIG. 11, the screen may transition to a confirmation screen shown on the right side of FIG. 11. On the confirmation screen shown on the right side of FIG. 11, the consumer can check information related to the transaction before finalizing the transaction. When the consumer's input to the Confirm button is detected on the confirmation screen shown on the right side of FIG. 11, the transaction can be finalized with the content shown on the confirmation screen on the right side of FIG. 11.

[0098] In the screen shown in Fig. 11, if showing only the token may mislead the consumer about the acquired power generation capacity (kW), the acquired token and the capacity (kW) corresponding to the acquired token may be displayed. Also, in the selection screen shown on the left side of Fig. 11, before the consumer makes a selection input, the consumer may be prompted to enter a consumer ID and authentication information to log in. In this case, the consumer ID and the consignment destination ID (including information about the consignment destination) may be stored in association with each other in trading platform 12.

[0099] FIG. 12 illustrates a screen that may be displayed on the output device 206 when the transaction amount has been determined and UTs are being traded. By displaying such a screen, the consumer can confirm the predicted power generation value of the power generation facility 13, i.e., the slots in which UTs can be purchased, on the selection screen shown on the left side of FIG. 12 . As shown on the selection screen on the left side of FIG. 12 , the unit of time for the energy transaction is not particularly limited, but may be, for example, 30 minutes. On the selection screen shown on the left side of FIG. 12 , a filled slot may indicate that there is no available slot, and an unfilled slot may indicate that there is available slot. Furthermore, the selection screen shown on the left side of FIG. 12 may include slots that cannot be selected as slots that are not eligible for trading. When a consumer selects an available slot on the selection screen shown on the left side of FIG. 12 , the screen may transition to a confirmation screen shown on the right side of FIG. 12 . On the confirmation screen shown on the right side of FIG. 12 , the consumer can confirm information related to the transaction before confirming the transaction. When the consumer's input on the Confirm button is detected on the confirmation screen shown on the right side of FIG. 12 , the transaction can be confirmed with the details shown on the confirmation screen on the right side of FIG. 12 .

[0100] On the selection screen shown on the left side of FIG. 12 , before a consumer makes a selection, the consumer may be prompted to enter a consumer ID and authentication information and log in. In this case, trading platform 12 may store the consumer ID and the consignment destination ID (including information about the consignment destination) in association with each other. Furthermore, trading platform 12 may use the consumer ID and authentication information to obtain a contract capacity (maximum received power) from, for example, an external server of an electric power utility (retailer) or OCCTO, and restrict transactions that exceed that capacity. For example, trading platform 12 may restrict transactions by prohibiting bids when the capacity is exceeded, displaying only available bids, displaying available and unavailable bids separately, or allowing only available bids to be selected. Furthermore, trading platform 12 may restrict transactions by permitting bids but disallowing successful bids. Furthermore, trading platform 12 may restrict transactions by displaying a warning screen and / or a warning message before finalizing a bid if the capacity is exceeded.

[0101] After a predetermined time has elapsed since the bidding, trading platform 12 may award the bid to the consumer who has submitted the highest bid. Trading platform 12 may also display a screen showing the details of the winning bid.

[0102] FIG. 13 illustrates a screen that may be displayed on the output device 206 when the transaction amount is fixed and UT is traded for a long period. By displaying such a screen, the consumer can check the predicted power generation value of the power generation facility 13, i.e., the facilities from which UT can be purchased, on the selection screen shown on the left side of FIG. 13 . As shown on the selection screen on the left side of FIG. 13 , the consumer can select at least one of, for example, a power generation facility named AAA and a power generation facility named BBB. As shown on the selection screen on the left side of FIG. 13 , when, for example, a power generation facility named AAA is selected, the display item may be displayed in a distinctive manner, such as by being surrounded by a thick border or by changing the color of the display item, to indicate the selection. When the consumer selects an item on the selection screen shown on the left side of FIG. 13 , the screen may transition to a confirmation screen shown on the right side of FIG. 13 . On the confirmation screen shown on the right side of FIG. 13 , the consumer can confirm information related to the transaction before confirming the transaction. When the consumer's input on the Confirm button is detected on the confirmation screen shown on the right side of FIG. 13 , the transaction can be confirmed as shown on the confirmation screen on the right side of FIG. 13 .

[0103] FIG. 14 illustrates a screen that may be displayed on the output device 206 when the transaction price is determined by bidding and UT is traded for a long period of time. By displaying such a screen, the consumer can check the predicted power generation value of the power generation facility 13, i.e., the facilities from which UT can be purchased, on the selection screen shown on the left side of FIG. 14 . As shown on the selection screen on the left side of FIG. 14 , the consumer can select at least one of, for example, a power generation facility named AAA and a power generation facility named BBB. Furthermore, for the power generation facility named AAA shown on the selection screen on the left side of FIG. 14 , the transaction price is determined by bidding. That is, since the transaction price has not yet been determined at this point, the price is not displayed for the power generation facility named AAA shown on the selection screen on the left side of FIG. 14 . As shown on the selection screen on the left side of FIG. 14 , when the power generation facility named AAA is selected, the display item may be surrounded by a thick frame or the color of the display item may be changed to distinguish it from others to indicate the selection. When the consumer selects an item on the selection screen shown on the left side of FIG. 14 , the screen may transition to a confirmation screen shown on the right side of FIG. 14 . On the confirmation screen shown on the right side of Fig. 14, the consumer can check information related to the transaction before finalizing the transaction and can also input a bid price for the selected power generation facility. Once the consumer has input a bid price on the confirmation screen shown on the right side of Fig. 14 and input to the Bid button is detected, the consumer can finalize the transaction (bid) with the details shown on the confirmation screen on the right side of Fig. 14.

[0104] When an input to the bid button is detected on the confirmation screen shown on the right side of Fig. 14, the screen may transition to, for example, a post-bid screen shown on the left side of Fig. 15. On the post-bid screen on the left side of Fig. 15, various information regarding the bid transaction may be displayed on the output device 206 together with the confirmed bid amount. Furthermore, as shown on the post-bid screen on the left side of Fig. 15, information such as the fact that the user who placed the bid in Fig. 14 is the current highest bidder may be displayed.

[0105] In a situation where the post-bid screen on the left side of Figure 15 is displayed, if, for example, another bidder places a higher bid, the bid shown on the left side of Figure 15 may not be awarded. In this case, the winning bid is not completed, so it may be possible to make an even higher bid by returning to the confirmation screen shown on the right side of Figure 14, for example.

[0106] On the other hand, when the post-bid screen on the left side of Fig. 15 is displayed and the trading period ends, a successful bid screen such as that shown on the right side of Fig. 15 may be displayed. The successful bid screen shown on the right side of Fig. 15 may display information indicating that the bid has been successful at the successful bid price upon the end of the trading period. Furthermore, when an input to the successful bid button is detected on the successful bid screen shown on the right side of Fig. 15, the successful bid for the bid with the content shown on the successful bid screen on the right side of Fig. 15 may be confirmed.

[0107] The selection screen shown on the left side of FIG. 11 shows available and unavailable slots as a trading scenario. Meanwhile, the equipment owner's input screen may display the slots to be traded, the slots not to be traded, and the slots that have already been sold, as shown in FIG. 16 . For example, as shown in FIG. 16 , when one of the slots shown as not to be traded is selected, the display mode, such as the color of the slot, may be changed to indicate that the slot has been selected. Subsequently, based on an input to the Confirm button as shown in FIG. 16 , the display mode, such as a change in color, of the slot may be changed to indicate that it is a trading target. As a prerequisite for such operation, the equipment owner may be required to log in by inputting their ID and authentication information. In this case, for example, the asset information storage unit 231 shown in FIG. 8 may store the equipment owner ID in association with information such as the facility name AAA and / or power generation capacity.

[0108] Furthermore, the selection screen shown on the left side of FIG. 12 shows available slots, unavailable slots, and slots that are not eligible for trading as a trading scenario. Meanwhile, the equipment owner's input screen may display available slots, unavailable slots, and sold slots, as shown in FIG. 17, for example. As shown in FIG. 17, for example, when one of the slots shown as unavailable for trading is selected, the display mode, such as the color of the slot, may be changed to indicate that the slot has been selected. Subsequently, based on an input of a confirm button as shown in FIG. 17, the display mode, such as a color change, of the slot may be changed to indicate that the slot is eligible for trading. As a prerequisite for such operation, the equipment owner may be required to log in by inputting their ID and authentication information. In this case, for example, the asset information storage unit 231 shown in FIG. 8 may store the equipment owner ID in association with information such as the facility name AAA and / or power generation capacity.

[0109] Registration and issuance of the facility owner's ID may be performed, for example, as follows. As described above, a consumer participating in a transaction may submit (transmit) in advance to an operator such as an external server information indicating the contract capacity (maximum received power) under contract with the power utility, along with a predetermined certificate. Similarly, an owner of a power generation facility participating in a transaction may submit (transmit) in advance to an operator such as an external server information regarding the facility to be traded, along with a predetermined certificate. Here, the predetermined certificate may be, for example, a copy of the company registry if the facility owner is a corporation, an order contract for the facility, a receipt verifying the purchase of the facility, and / or a certificate of the facility issued by a third-party organization.

[0110] The information submitted in this manner may be stored in the asset information storage unit 231 in association with the equipment owner's identification information or authentication information, which will be described below. At least one of the equipment owner's identification information and authentication information may be issued to the equipment owner, for example, from an external server. The equipment owner can participate in a transaction by inputting at least this identification information and authentication information into the trading platform 12 at the time of the transaction. By using this input identification information and authentication information, the trading platform 12 can obtain information about the equipment of the equipment owner who is participating in the transaction from the asset information storage unit 231 and display it on a screen that can be displayed when trading, etc.

[0111] Any time may be set for the time periods 1 to 18 shown in Figures 12 and 17. For example, one time period may be 30 minutes long, and one day may be displayed as 1 to 48 time periods.

[0112] Furthermore, for example, in a trading platform, switching of electricity retailers may be performed by smart contracts. By using APIs, necessary data can be obtained, so switching of electricity retailers may be performed on the trading system side.

[0113] The power procurement system of this embodiment may automatically create information about a self-consignment plan based on information about the transaction after the above-mentioned matching process is completed. The power procurement system of this embodiment may transmit the information about the self-consignment plan created in this manner, together with information about the consumer who performed the transaction, to, for example, OCCTO, after the above-mentioned matching process is completed. The plan information transmitted to, for example, OCCTO may include various information, such as information about the sender of the plan, information about the destination of the plan, the planned energy amount, the planned time period, and / or the predicted power generation value of the power generation facility. In this way, a self-consignment plan can be created and reported to the relevant parties before self-consignment is performed.

[0114] Furthermore, the electricity procurement system of this embodiment may automatically conclude a contract necessary for self-consignment with an electricity retailer that has a contract to supply electricity to the consumer's facility, using a smart contract, etc. In addition, in the electricity procurement system of this embodiment, when a transaction is concluded by the sales processing unit 216, the management server 2 may create a self-consignment plan by the day before the self-consignment is to be executed, and submit the plan to a predetermined organization such as OCCTO.

[0115] Next, examples of self-consignment contracts in the power procurement system according to this embodiment will be further described for the following two cases.

[0116] (1) When the electricity retailer is the same

[0117] The case where the electricity retailer is the same may be the case where the electricity retailer with which the contract to handle electricity generated from the power generation facility is the same as the electricity retailer with which the contract to supply electricity to the consumer's facility is the same. In such a case, the electricity procurement system according to the present embodiment may automatically conclude a self-consignment contract for the matching process with the electricity retailer by using a smart contract or the like.

[0118] (2) When the electricity retailer is different

[0119] The case where the electricity retailer is the same may be a case where the electricity retailer with which the contract to handle electricity generated from the power generation facility is different from the electricity retailer with which the contract to supply electricity to the consumer's facility is different. In such a case, the electricity procurement system according to the present embodiment may automatically conclude a self-consignment contract for the matching process with each electricity retailer using a smart contract or the like.

[0120] In these cases, the electricity procurement system of this embodiment may conclude a self-consignment contract in addition to the above-mentioned matching process. Also, the electricity procurement system of this embodiment may take measures to complete matching only when the electricity retailer that has a contract to handle electricity generated by the power generation facility is the same as the electricity retailer that has a contract to supply electricity to the consumer's facility.

[0121] In this case, a party under contract with an electricity retailer is a party under contract to provide or supply electricity to facilities or equipment owned by the party. For example, the electricity procurement system may be configured to conduct transactions only between multiple consumers under contract with the same electricity retailer and the owner of the power generation facility. The electricity procurement system may also prohibit consumers under contract with an electricity retailer other than the one under contract with the owner of the power generation facility from participating in transactions.

[0122] Next, the manner in which tokens are purchased in the power procurement system of this embodiment will be described in more detail.

[0123] Fig. 18 is a diagram showing an example of token purchase in the power procurement system of this embodiment. In Fig. 18, for example, a case will be described in which the owner of the power generation facility is a power retailer.

[0124] In the above-described embodiment, an example has been described in which an owner of a power generation facility participates in a transaction as a facility owner by registering information about the power generation facility in the transaction PF. In an electricity procurement system according to one embodiment, a retailer may also participate in a transaction as a facility owner of a power generation facility such as a solar panel. In such a case, the configuration other than that described above may be the same as that of the above-described embodiment.

[0125] For example, a retailer can increase the credibility of participants in a transaction by participating as the owner of a power generation facility. In other words, in a transaction using a trading platform, a consumer can acquire the right to receive the electricity associated with the security token or utility token of a power generation facility by bidding successfully for those tokens. However, if the retailer is already supplying electricity, they have a proven track record of supplying electricity, which can reduce the consumer's anxiety that they may not be able to receive the electricity associated with the tokens they have won.

[0126] In one embodiment, for example, a retailer that already has power generation equipment may participate in the transaction. Also, in another embodiment, for example, a retailer may collect funds from a consumer group consisting of multiple consumers, purchase power generation equipment such as solar panels, and install it on a specified piece of land to enable power generation. Such a transaction may be conducted in the same manner as in the above-described embodiment. A consumer who wins a bid will receive electricity from the retailer, which is the facility owner, in accordance with the tokens they have won.

[0127] On the other hand, as shown in Fig. 18, when funds are collected from a consumer group to purchase power generation facilities such as solar panels 13, the power procurement system may issue or grant a predetermined amount of tokens to this consumer group without conducting a transaction as in the above-described embodiment. In this case, in addition to the consumers, the retailer 19 may also contribute funds. As a result, the consumer group will be supplied with electricity corresponding to the tokens from the retailer 19, which is the facility owner.

[0128] In addition, the power procurement system according to an embodiment may issue or grant tokens to each consumer in a consumer group so that each consumer can receive a corresponding supply of power. In this case, the tokens may be distributed equally among the consumers or may be allocated according to the funds provided.

[0129] In Figure 18, retailer 19 may be, for example, the owner of the solar panels. Retailer 19 may purchase the solar panels directly using funds collected from a group of customers. Also, as shown in Figure 18, retailer 19 may virtually partition the solar panels while retaining ownership and retailing them.

[0130] For example, if the power procurement system issues 100 security tokens to a power generation facility associated with a consumer group's investment, the power procurement system may provide 2 tokens, which is 2% of the total investment amount, to the consumer who invested. For example, if the maximum daily output of the power generation facility is 100 kWh, a consumer who is provided with 2 tokens will be supplied with 2 kW of power per day from the facility owner, retailer 19. Here, as long as the consumer holds these 2 tokens, the consumer may be supplied with 2 kW of power per day from the facility owner, retailer 19, semi-permanently. However, this 2 kW per day is an actual value or a theoretical value. Therefore, in reality, the supplied power may decrease due to deterioration or breakdown of the power generation facility.

[0131] 18, even a consumer group that has not provided funds for the purchase of solar panels may be able to purchase tokens from the retailer 19, the consumer group that provided the funds, or a consumer belonging to the consumer group that provided the funds. If tokens are purchased in this way, the consumer may be able to receive power supply from the retailer 19. For example, as shown in FIG. 18, assume that a consumer that is household X that has not provided funds purchases two tokens, which is 2% of the total funds, from the retailer 19 that provided part of the funds. In this case, based on the same idea as above, this consumer may be considered to have purchased semi-permanent tokens equivalent to 2 kW per day from the retailer 19.

[0132] Furthermore, if a consumer group that has not provided funds purchases tokens from the retailer 19 that has provided part of the funds, the consumer group can be supplied with electricity corresponding to the tokens purchased from the retailer 19. In this case, the electricity procurement system may manage to provide the tokens to the consumer group. Alternatively, the consumer group may enter into a supply contract for a predetermined amount of electricity corresponding to a predetermined token without the intervention of the electricity procurement system, so that the consumer group holds the tokens in a pseudo manner via the retailer 19.

[0133] In this way, by having the electricity retailer become the direct trading partner, it is possible to ensure that the power generation equipment being traded actually exists and / or to increase the reliability of the information about the equipment displayed at the time of the transaction.

[0134] 19 is a diagram showing an example of a monetary claim in the power procurement system of this embodiment. In FIG. 19, the case where the owner of the power generation facility is a power retailer will also be described.

[0135] In the above-described embodiment, an example has been described in which an owner of a power generation facility participates in a transaction as a facility owner by registering information about the power generation facility in the transaction PF. In an electricity procurement system according to one embodiment, a retailer may also participate in a transaction as a facility owner of a power generation facility such as a solar panel. In such a case, the configuration other than that described above may be the same as that of the above-described embodiment.

[0136] For example, by the retailer itself participating in the transaction as the facility owner of the power generation facility, it is possible to increase the credibility of the participants in the transaction, as in the case shown in FIG.

[0137] In one embodiment, an example will be described in which the retailer 19 is the facility owner of a power generation facility that generates 10,000 kWh of electricity per month, as shown in Figure 19. In this case, the retailer 19 may register the asset information of the power generation facility in the electricity procurement system according to one embodiment, thereby becoming able to participate in the trading PF as the facility owner.

[0138] In this case, an electricity procurement system according to one embodiment may issue, for example, 100 tokens as security tokens. If a consumer, which is household X, wins a bid for two tokens from the trading PF of the electricity procurement system, the consumer will obtain the right to receive 200 kWh of electricity per month from the retailer 19, which corresponds to 2% of the monthly 10,000 kWh of electricity. Here, if the consumer participating in the transaction has an electricity supply contract with the retailer 19, assume that the monthly electricity usage fee for household X is, for example, 450 kWh. In this case, by offsetting the right to receive 200 kWh of electricity obtained through the transaction, it may be determined that 250 kWh of electricity has been used, which is calculated by subtracting 200 kWh from 450 kWh.

[0139] In this case, household X shown in Fig. 19 may be billed for the usage fee of 250 kWh of electricity by the retailer 19. In this way, the amount of electricity to be billed is determined by deducting the amount of generated electricity corresponding to the tokens acquired through the transaction from the amount of electricity purchased from the retailer 19, which is called "net metering."

[0140] In this way, if a consumer (household X) completes a transaction and obtains tokens worth 2% of a 10,000 kWh power generation facility in one month, the retailer with which the transaction took place may deduct 2% (200 kWh) of the amount of electricity from the amount of electricity billed each month.

[0141] FIG. 20 is a flowchart illustrating the operation of power supply by net metering in a power procurement system according to one embodiment.

[0142] In the operation shown in FIG. 20, the operations in steps S301 to S305 may be performed in the same manner as the operation shown in FIG.

[0143] As shown in FIG. 20, once the amount of power generation is allocated to the divided holders according to the token holders in step S305, the management server 2 may supply power by the net metering as described above (S401).

[0144] Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present disclosure and is not intended to limit the present disclosure. The present disclosure may be modified or improved without departing from the spirit thereof, and equivalents thereof are also included in the present disclosure.

[0145] For example, in this embodiment, the location of the ownership and offtake rights of the power generation facility 13 is managed using tokens issued by the blockchain 4. However, in one embodiment, the location management as described above does not necessarily have to be performed using blockchain technology. For example, the ownership and offtake rights may be managed in a predetermined database, and the administrator of the database (the operator of the management server 2) may guarantee the authenticity of the contents. That is, in one embodiment, tokens may be issued (recorded) in a predetermined database.

[0146] 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. However, the management server 2 may be provided with an owner information storage unit that stores the owner information.

[0147] In addition, the electricity procurement system of one embodiment may collect a fee at the time of transaction or a fee at the time of self-consignment.

[0148] In one embodiment of the power procurement system, the predicted amount of power to be generated may be different for each time period. Furthermore, in one embodiment of the power procurement system, if the predicted amount of power to be generated is incorrect, measures such as imposing a penalty depending on the degree of error may be taken. In one embodiment of the power procurement system, instead of displaying the actual predicted value as the predicted value of power to be generated, a predetermined percentage may be displayed for safety purposes, and then trading may be performed. For example, if the predicted value of power to be generated is actually 1000 kWh, trading may be performed by deliberately displaying 900 kWh.

[0149] In the power procurement system of one embodiment, the power generation facility 13 may be not only a solar panel (solar cell) that generates solar power, but also, for example, a storage battery (including an electric vehicle (EV)). Furthermore, in the power procurement system of one embodiment, if the power generation facility 13 includes a storage battery, the storage battery may function as a power buffer.

[0150] In addition, in the power procurement system of one embodiment, if there is a surplus of power generated by the power generation facility 13, the surplus may be purchased by the power transmission and distribution company. In addition, in the power procurement system of one embodiment, if there is a shortage of power generated by the power generation facility 13, the power purchasing party (power generation side) may pay a penalty.

[0151] Furthermore, in one embodiment of the power procurement system, a mechanism may be established in which the amount of power, etc. that is expected to be obtained in the future according to the investment payback period is reflected in the present value and discounted.

[0152] <Disclosures> The present disclosure also includes the following configurations.
