Description

本発明は、環境価値取引対価算出装置、環境価値取引対価算出方法および環境価値取引対価算出プログラムに関し、特に令和4年4月1日より施行された「再生可能エネルギー電気の利用の促進に関する特別措置法」におけるFIP(Feed-in Premium)制度を活用した環境価値取引対価算出装置、環境価値取引対価算出方法および環境価値取引対価算出プログラムに関するものである。 The present invention relates to an environmental value transaction consideration calculation device, an environmental value transaction consideration calculation method, and an environmental value transaction consideration calculation program. The present invention relates to an environmental value transaction consideration calculation device, an environmental value transaction consideration calculation method, and an environmental value transaction consideration calculation program utilizing the FIP (Feed-in Premium) system under the Law Concerning Measures.

PPA(Power Purchase Agreement)とは、小売電気事業者または需要家と発電事業者との間で締結する電力を売買する契約のことである。
そして、企業や自治体などの需要家が発電事業者から自然エネルギー(再生可能エネルギー)の電力を長期(通常15年以上)に購入する契約は、コーポレートPPAと呼ばれている。
A PPA (Power Purchase Agreement) is a contract for buying and selling electric power concluded between a retail electric power company or a consumer and a power generation company.
A long-term (usually 15 years or more) contract for consumers such as companies and local governments to purchase natural energy (renewable energy) power from power producers is called a corporate PPA.

このコーポレートPPAには、需要家の敷地内に発電事業者が発電設備を設置して、この発電設備で発電した電力を現地(オンサイト)で供給するオンサイトPPAと、需要家の事業拠点から離れた場所にある発電設備から送配電ネットワークを経由して需要家の事業拠点に電力の供給するオフサイトPPAとが存在する。 This corporate PPA includes an on-site PPA where a power generation company installs power generation equipment on the premises of the customer and supplies the power generated by this power generation equipment locally (on-site), and There is an off-site PPA that supplies power from a remote power generation facility to a customer's business location via a power transmission and distribution network.

そして、このオフサイトPPAには、発電事業者が電力および環境価値(CO2を排出しないなどの効果)を小売電気事業者に対して固定価格で販売し、その電力および環境価値を、小売電気事業者が需要家に固定価格で販売するフィジカルPPAと、発電事業者が電力を卸電力市場で売却し、固定価格の環境価値を直接または小売電気事業者を経由して需要家に販売し、小売電気事業者が電力のみまたは電力と環境価値をセットで需要家に販売するバーチャルPPA(以下、「第1のバーチャルPPA形態」という。)とが存在する(例えば、非特許文献1、非特許文献2)。 In this off-site PPA, power producers sell electric power and environmental value (effects such as not emitting CO2) to retail electric power producers at a fixed price, and sell the electric power and environmental value to retail electric power producers. A physical PPA, in which a power producer sells electricity to consumers at a fixed price, and a power generator sells electricity in the wholesale electricity market, and the fixed-price environmental value is sold to consumers directly or via a retail electricity supplier, There is a virtual PPA (hereinafter referred to as a “first virtual PPA form”) in which electric power companies sell only electric power or electric power and environmental value as a set to consumers (for example, Non-Patent Document 1, Non-Patent Document 2).

バーチャルPPAでは、バーチャルPPAの対象になる電力を発電事業者が全量を卸電力市場に売却するが、この時に発電事業者が得られる電力の売却価格は卸電力市場における市場価格で決まる。
しかし、発電事業者が発電設備を開発するためには金融機関等からの融資(資金調達)がほぼ必須であるところ、上述した「第1のバーチャルPPA形態」では、卸電力市場における電力の市場価格に連動して発電事業者の収入が増減し、発電事業者のキャッシュフローが安定しないため、金融機関等から融資を受けることが極めて困難となる。
In a virtual PPA, a power generator sells the entire amount of power subject to the virtual PPA to the wholesale power market, but the selling price of the power obtained by the power generator at this time is determined by the market price in the wholesale power market.
However, in order for power producers to develop power generation facilities, financing (financing) from financial institutions, etc. is almost essential. Since the income of the power generation company fluctuates in tandem with the price, and the cash flow of the power generation company is unstable, it becomes extremely difficult to obtain financing from financial institutions.

「コーポレートPPA実践ガイドブック」(自然エネルギー財団);https://www.renewable-ei.org/pdfdownload/activities/REI_GuidebookCorpPPA.pdf“Corporate PPA Practical Guidebook” (Renewable Energy Institute); https://www.renewable-ei.org/pdfdownload/activities/REI_GuidebookCorpPPA.pdf 「日本のコーポレートPPA」(自然エネルギー財団);https://www.renewable-ei.org/pdfdownload/activities/REI_JPcorpPPA2021.pdf“Japanese Corporate PPA” (Renewable Energy Institute); https://www.renewable-ei.org/pdfdownload/activities/REI_JPcorpPPA2021.pdf

そこで、発電事業者の収入を安定させるために、「発電事業者と需要者とのあいだで合意した電力と環境価値との合計額である固定価格と、卸電力市場における電力の実際の市場価格との差額を、実際の環境価値の代金として需要家が精算する」というバーチャルPPA(以下、「第2のバーチャルPPA形態」という。)が考えられるが、このバーチャルPPAは次のような問題点がある。 Therefore, in order to stabilize the income of power producers, the fixed price, which is the total amount of electricity and environmental value agreed between the power producer and consumers, and the actual market price of electricity in the wholesale electricity market. The consumer pays the difference between the actual environmental value and the actual environmental value" (hereinafter referred to as the "second virtual PPA form"), but this virtual PPA has the following problems: There is

(1)需要家の問題
卸電力市場における電力の市場価格が大きく下落した際に、需要家の負担する環境価値の代金が極めて高額(たとえば、固定価格を10数円/kWhで設定した場合、市場価格が0.01円/kWhとなると、通常1円未満/kWhで購入できる環境価値の代金が10数円/kWhになる)になってしまう。
したがって、「第2のバーチャルPPA形態」は、市場価格の変動リスクを甘受することになるため、需要家にとっては受け入れがたい契約となっている。
(1) Problems with consumers When the market price of electricity in the wholesale electricity market drops sharply, the cost of environmental value borne by consumers is extremely high (for example, if the fixed price is set at 10 yen/kWh, If the market price is 0.01 yen/kWh, the price for the environmental value that can be purchased for less than 1 yen/kWh will be around 10 yen/kWh).
Therefore, the "second virtual PPA form" is an unacceptable contract for consumers because they have to accept the risk of market price fluctuations.

(2)発電事業者の問題
発電事業者としては、「第2のバーチャルPPA形態」を採用することで、「第1のバーチャルPPA形態」における、収入が固定化できないという問題は解決するとも考えられる。
しかし、環境価値の代金について、市場価格を参照して決定するというスキームは商品先物取引法の店頭商品デリバティブ対象取引となり、特定店頭商品デリバティブ取引業者の届け出が必要になるなど、手続きが極めて煩雑となる。
加えて、上記需要家の問題で記載したように、発電事業者としては金融機関等から融資を受けるために、特定の需要家と、15年以上の長期間を契約期間とする上記の契約を締結する必要があるが、市場価格の変動リスクを甘受して契約を締結する需要家は存在しないため、上述した「第2のバーチャルPPA形態」は現実的ではない。
(2) Problems of power generation companies As power generation companies, we believe that adopting the “second virtual PPA format” will solve the problem that income cannot be fixed in the “first virtual PPA format”. be done.
However, the scheme of determining the price of environmental value by referring to the market price is subject to over-the-counter commodity derivatives transactions under the Commodity Futures Trading Law, and the procedures are extremely complicated, such as the need to notify a specified over-the-counter commodity derivatives trader. Become.
In addition, as described in the consumer problem above, in order to receive financing from financial institutions, etc., power generation companies enter into contracts with specific consumers for a long period of 15 years or more. Although it is necessary to conclude a contract, there is no consumer who accepts the risk of market price fluctuations and concludes a contract, so the above-mentioned "second virtual PPA form" is not realistic.

そこで、2022年度4月より開始されたFIP制度を活用すると、発電事業者が市場価格の変動リスクを軽減できるため、需要家が環境価値価格を固定化でき、「発電事業者は卸電力市場における市場価格と、FIP制度における供給促進交付金と、定額の環境価値代金とを受け取り、需要家は環境価値を入手する」というバーチャルPPA(以下、「第3のバーチャルPPA形態」という。)が実現する可能性がある。 Therefore, by utilizing the FIP system that started in April 2022, power producers can reduce the risk of market price fluctuations, so consumers can fix the environmental value price. Market price, supply promotion subsidies under the FIP system, and a fixed amount of environmental value fee are received, and the consumer obtains the environmental value” (hereinafter referred to as “third virtual PPA form”). there's a possibility that.

ここで、FIP制度は、固定価格買取制度(FIT制度)の後継となる制度であり、発電事業者が卸電力取引市場や相対取引で発電した再生可能エネルギーを市場に供給した場合に、基準価格と参照価格(市場取引などによって発電事業者が期待できる収入分のことであり、卸電力取引市場価格等と連動し、1カ月単位で見直される価格)との差額をプレミアム(供給促進交付金)として交付する制度となっている。
なお、このFIP制度は、令和4年4月1日より施行される「再生可能エネルギー電気の利用の促進に関する特別措置法(旧:電気事業者による再生可能エネルギー電気の調達に関する特別措置法)(平成二十三年法律第百八号)」(以下、「再エネ促進法」という。)で詳細に規定されている。
そして、上記の「基準価格」の定義、「参照価格」に相当する額の算出方法、供給促進交付金の額の算出方法については、再エネ促進法および「再生可能エネルギー電気の利用の促進に関する特別措置法施行規則(旧:電気事業者による再生可能エネルギー電気の調達に関する特別措置法施行規則)(平成二十四年経済産業省令第四十六号)(以下、「再エネ促進法施行規則」という。)」で詳細に定められている。
Here, the FIP system is a system that succeeds the feed-in tariff system (FIT system), and when power generators supply renewable energy generated in the wholesale electricity market or negotiated transactions to the market, the standard price and the reference price (the amount of income that power generation companies can expect from market transactions, etc., which is linked to the wholesale power market price and reviewed on a monthly basis), the premium (supply promotion subsidy) It is a system to issue as
This FIP system is based on the Act on Special Measures Concerning Promotion of Use of Renewable Energy Electricity (former: Act on Special Measures Concerning Procurement of Renewable Energy Electricity by Electric Utilities), which will be enforced on April 1, 2022. (Act No. 108 of 2011)” (hereinafter referred to as the “Renewable Energy Promotion Act”).
Regarding the definition of the above "reference price", the calculation method of the amount equivalent to the "reference price", and the calculation method of the amount of the supply promotion subsidy, the Renewable Energy Promotion Act and the Ordinance for Enforcement of the Act on Special Measures (former: Ordinance for Enforcement of the Act on Special Measures Concerning Procurement of Renewable Energy Electricity by Electric Utilities) (Ministry of Economy, Trade and Industry Ordinance No. 46 of 2012) ".")".

したがって、このFIP制度を活用することで、卸電力市場における市場価格が低い場合は、発電事業者の受け取れるプレミアムが高くなり、発電事業者の得る収入が一定程度確保されることが期待できるため、上述した「第3のバーチャルPPA形態」があり得る。 Therefore, by utilizing this FIP system, when the market price in the wholesale electricity market is low, the premium that the power generation company can receive will increase, and it can be expected that the income earned by the power generation company will be secured to a certain extent. There may be a "third virtual PPA configuration" as described above.

しかし、FIP制度によると、日々変化する卸電力市場における市場価格と1ヶ月単位で見直されるFIP制度における参照価格とが月次ベースでは一致しないため、発電事業者の受け取る総額(市場価格とプレミアムと環境価値の代金との合計額)が、発電事業者の希望する価格に満たない虞がある。
すなわち、FIP制度を活用した「第3のバーチャルPPA形態」であっても、発電事業者の収入が安定しない可能性がある。
However, according to the FIP system, the market price in the wholesale electricity market, which changes daily, and the reference price in the FIP system, which is reviewed on a monthly basis, do not match on a monthly basis. environmental value) may be less than the price desired by the power generation company.
In other words, even in the "third virtual PPA format" that utilizes the FIP system, there is a possibility that the income of power producers will not be stable.

そこで、本発明は、前述したような従来技術の問題を解決するものであって、すなわち、本発明の目的は、発電事業者が安定した希望売電単価で電力および環境価値を売却可能とすると共に環境価値購入者が発電事業者に支払う環境価値取引対価の変動幅を抑制する、環境価値取引対価算出装置、環境価値取引対価算出方法および環境価値取引対価算出プログラムを提供することである。 Therefore, the present invention solves the problems of the prior art as described above, that is, the object of the present invention is to enable power generation companies to sell electric power and environmental value at a stable asking price. It is also an object of the present invention to provide an environmental value transaction consideration calculation device, an environmental value transaction consideration calculation method, and an environmental value transaction consideration calculation program that suppress the fluctuation range of the environmental value transaction consideration paid by the environmental value purchaser to the power generator.

According to the environmental value trading consideration calculation device of the first aspect of the invention, it is possible to input a fixed desired electricity sales unit price which is the electricity sales unit price desired by the power generation company and the power generation company receipt unit price received by the power generation company. Since the amount to be paid to the power generation company and the suggested power sale price match with the provision of a means for accepting the power sale price acceptance means, the power generation company can reliably sell the power and environmental value at the suggested power sale price. can.
In addition, the environmental value purchaser payment amount calculation means receives at least the desired electricity sales unit price received by the electricity sales unit price receiving means, the unit price or amount of the supply promotion subsidy under the FIP system, and the area at the installation location received by the installation location receiving means. The environmental value purchaser's payment amount is calculated based on the price, the amount of the lump-sum payment for the environmental value transaction consideration, and the power generation amount acquired by the power generation amount acquisition means, and the amount of the lump-sum payment is changed. When the area price becomes expensive because the amount paid by the environmental value purchaser as consideration for the value transaction is calculated based on at least the desired electricity sales unit price, the area price and installation location, and the unit price or amount of the supply promotion subsidy. In addition, the amount paid by environmental value purchasers as consideration for environmental value transactions is reduced and the amount of lump sum is increased. The amount of money paid by the purchaser can be kept low.
In other words, it is possible for the power generator to sell the electric power and the environmental value at a stable selling price of electricity, and to suppress the fluctuation range of the environmental value transaction consideration paid by the environmental value purchaser to the power generator.

上述した「第2のバーチャルPPA形態」は、卸電力市場における電力の市場価格が高騰し固定価格を超えた場合、発電事業者は環境価値購入者に環境価値を販売したにもかかわらず、環境価値購入者に対して固定価格と市場価格との差分を支払わなければならないことになる。
このような精算は、商慣習になじまないだけでなく、純額決済となり、デリバティブとして、経理処理も煩雑になる。
そこで、請求項2に係る発明の環境価値取引対価算出装置によれば、請求項1に係る発明の環境価値取引対価算出装置が奏する効果に加えて、売電単価受付手段が受け付けた希望売電単価、供給促進交付金の単価または額、環境価値購入者支払金額を算出するための算出手数料、設置場所受付手段が受け付けた設置場所におけるエリアプライス、環境価値取引対価の支払いのための一時金の額、発電量取得手段の取得した発電量に基づいて環境価値購入者支払金額算出手段の算出した環境価値購入者支払金額が0円未満であった場合、環境価値購入者支払金額算出手段が環境価値購入者支払金額を0円とすると共に一時金の額を変化させることにより、希望売電単価、エリアプライス、算出手数料、供給促進交付金の単価または額などが如何なる額であっても、環境価値購入者支払金額が0円未満にならないため、会計上複雑になる純額決済を回避することができる。
また、供給促進交付金を環境価値購入者支払金額の算出に組み込むことで、FIP制度における参照価格と市場価格とが相殺されるため、環境価値購入者支払金額が市場価格を参照していないこととなり、店頭商品デリバティブ取引を規制する商品先物取引法が適用外となる。
In the above-mentioned "second virtual PPA form", when the market price of electricity in the wholesale electricity market soars and exceeds the fixed price, even though the power generator sold the environmental value to the environmental value purchaser, the environmental You will have to pay the value buyer the difference between the fixed price and the market price.
Such settlement not only does not conform to commercial practices, but is a net settlement, and as a derivative, the accounting process becomes complicated.
Therefore, according to the environmental value transaction consideration calculation device of the invention of claim 2, in addition to the effects of the environmental value transaction consideration calculation device of the invention of claim 1, unit price, unit price or amount of supply promotion subsidy, calculation fee for calculating environmental value purchaser payment amount, area price at installation site accepted by installation site reception means, lump-sum payment for environmental value transaction consideration If the environmental value purchaser payment amount calculated by the environmental value purchaser payment amount calculation means based on the amount of power generation acquired by the power generation amount acquisition means is less than 0 yen, the environmental value purchaser payment amount calculation means By setting the value purchaser's payment amount to 0 yen and changing the amount of the lump-sum payment, the desired electricity sales unit price, area price, calculation fee, supply promotion subsidy unit price or amount, etc. Since the value purchaser's payment amount does not become less than 0 yen, it is possible to avoid net settlement, which is complicated in terms of accounting.
In addition, since the reference price in the FIP system and the market price are offset by incorporating the supply promotion subsidy into the calculation of the environmental value purchaser payment amount, the environmental value purchaser payment amount does not refer to the market price. As a result, the Commodity Futures Trading Act, which regulates over-the-counter commodity derivative transactions, will not apply.

あるいは、請求項3に係る発明の環境価値取引対価算出装置によれば、請求項1に係る発明の環境価値取引対価算出装置が奏する効果に加えて、環境価値購入者支払金額算出手段が、売電単価受付手段が受け付けた希望売電単価、供給促進交付金の単価または額、設置場所受付手段が受け付けた設置場所におけるエリアプライス、環境価値取引対価の支払いのための一時金の額、発電量取得手段の取得した発電量に基づいて環境価値購入者支払金額算出手段の算出した環境価値購入者支払金額が0円未満であった場合に、環境価値購入者支払金額算出手段が環境価値購入者支払金額を0円とすると共に一時金の額を変化させることにより、希望売電単価、エリアプライス、供給促進交付金の単価または額などが如何なる額であっても、環境価値購入者支払金額が0円未満にならないため、会計上複雑になる純額決済を回避することができる。
また、供給促進交付金を環境価値購入者支払金額の算出に組み込むことで、FIP制度における参照価格と市場価格とが相殺されるため、環境価値購入者支払金額が市場価格を参照していないこととなり、店頭商品デリバティブ取引を規制する商品先物取引法が適用外となる。
Alternatively, according to the environmental value transaction consideration calculation device of the invention of claim 3, in addition to the effects of the environmental value transaction consideration calculation device of the invention of claim 1, the environmental value purchaser payment amount calculation means Suggested electricity sales unit price accepted by electricity unit price acceptance means, unit price or amount of supply promotion subsidy, area price at installation location accepted by installation location acceptance means, lump-sum amount for payment of consideration for environmental value transaction, power generation amount If the environmental value purchaser payment amount calculated by the environmental value purchaser payment amount calculation means based on the amount of power generation acquired by the acquisition means is less than 0 yen, the environmental value purchaser payment amount calculation means By setting the payment amount to 0 yen and changing the amount of the lump-sum payment, the environmental value purchaser's payment amount can be changed regardless of the desired electricity sales unit price, area price, supply promotion subsidy unit price or amount, etc. Since it will not be less than 0 yen, it is possible to avoid net settlement, which is complicated in terms of accounting.
In addition, since the reference price in the FIP system and the market price are offset by incorporating the supply promotion subsidy into the calculation of the environmental value purchaser payment amount, the environmental value purchaser payment amount does not refer to the market price. As a result, the Commodity Futures Trading Act, which regulates over-the-counter commodity derivative transactions, will not apply.

請求項4に係る発明の環境価値取引対価算出装置によれば、請求項1乃至請求項3のいずれか1項に係る発明の環境価値取引対価算出装置が奏する効果に加えて、供給促進交付金の単価を算出する供給促進交付金算出手段を備えていることにより、電力広域的運営推進機関から供給促進交付金の単価または額を通知されるよりも早く供給促進交付金の額を計算するため、電力広域的運営推進機関による処理を待たずに調整金額や環境価値購入者支払金額を算出し、発電事業者および環境価値購入者が早期に決済をすることができる。 According to the environmental value transaction consideration calculation apparatus of the invention of claim 4, in addition to the effects of the environmental value transaction consideration calculation apparatus of the invention of any one of claims 1 to 3, supply promotion subsidies To calculate the amount of the supply promotion subsidy earlier than the unit price or amount of the supply promotion subsidy is notified from the Organization for Cross-regional Coordination of Transmission Operators, by having a supply promotion subsidy calculation means that calculates the unit price of , the adjustment amount and the environmental value purchaser's payment amount can be calculated without waiting for processing by the Organization for Cross-regional Coordination of Transmission Operators, and the power generation business operator and the environmental value purchaser can make early settlements.

請求項5に係る発明の環境価値取引対価算出方法によれば、売電単価受付手段が発電事業者の希望する売電単価であると共に発電事業者が受け取る発電事業者受取単価である定額の希望売電単価の入力を受け付ける希望売電単価受付ステップを備えていることにより、発電事業者へ支払われる金額と希望売電単価と一致するため、発電事業者が確実に希望売電単価で電力および環境価値を売却することができる。
環境価値購入者支払金額算出手段が、少なくとも、希望売電単価受付ステップで売電単価受付手段が受け付けた希望売電単価、FIP制度における供給促進交付金の単価または額、発電設備設置場所受付ステップで設置場所受付手段が受け付けた設置場所におけるエリアプライス、環境価値取引対価の支払いのための一時金の額、発電量取得手段が取得した発電量に基づいて、環境価値購入者支払金額を算出すると共に一時金の額を変化させる環境価値購入者支払金額算出ステップを備えていることにより、環境価値取引対価としての環境価値購入者支払金額が、少なくとも、希望売電単価、エリアプライスおよび設置場所、供給促進交付金の単価または額に基づいて算出されるため、エリアプライスが高価になった際に環境価値取引対価としての環境価値購入者支払金額を低額にすると共に一時金の額を増加させ、エリアプライスが安価になった際には増加した一時金を切り崩して充当して環境価値取引対価としての環境価値購入者支払金額を低額に抑えることができる。
すなわち、発電事業者が安定した希望売電単価で電力および環境価値を売却可能とすると共に環境価値購入者が発電事業者に支払う環境価値取引対価の変動幅を抑制することができる。
According to the environmental value transaction consideration calculation method of the invention according to claim 5, the electricity sales unit price receiving means is the electricity sales unit price desired by the power generation business operator and the desired fixed amount that is the power generation business unit receipt price received by the power generation business operator. Since the amount to be paid to the power generation company matches the suggested power sale price by providing the suggested power sale price reception step for accepting the input of the power sale price, the power generation company can reliably purchase electricity and electricity at the suggested power sale price. Environmental value can be sold.
The environmental value purchaser payment amount calculation means receives at least the desired electricity sales unit price received by the electricity sales unit price receiving means in the desired electricity sales unit price receiving step, the unit price or amount of the supply promotion subsidy under the FIP system, and the power generation facility installation location receiving step. Calculate the amount paid by the environmental value purchaser based on the area price at the installation location accepted by the installation location acceptance means, the lump-sum amount for payment of the consideration for the environmental value transaction, and the power generation amount acquired by the power generation acquisition means. The environmental value purchaser payment amount calculation step for changing the amount of the lump-sum payment together with the Since it is calculated based on the unit price or amount of the supply promotion subsidy, when the area price becomes expensive, the amount paid by the environmental value purchaser as consideration for the environmental value transaction will be reduced and the amount of the lump-sum payment will be increased. When the area price becomes cheaper, the increased lump-sum payment can be cut down and appropriated to keep the environmental value purchaser's payment amount as consideration for the environmental value transaction at a low amount.
In other words, it is possible for the power generator to sell the electric power and the environmental value at a stable selling price of electricity, and to suppress the fluctuation range of the environmental value transaction consideration paid by the environmental value purchaser to the power generator.

<1.日本卸電力取引所および電力広域的運営推進機関について>
はじめに、FIP制度において重要な役割を果たす日本卸電力取引所および電力広域的運営推進機関について説明する。
<1. About the Japan Electric Power Exchange and the Organization for Cross-regional Coordination of Transmission Operators >
First, the Japan Electric Power Exchange and the Organization for Cross-regional Coordination of Electric Power Operations, which play an important role in the FIP system, will be explained.

<1.1.日本卸電力取引所について>
日本卸電力取引所(JEPX)は、電力の現物取引および先渡取引などを仲介する取引所である。
そして、日本卸電力取引所は、現物電気の売却先を探している事業者と電気の需要を満たすために電気を調達したい事業者の間で、翌日渡しの電気の売買を行う一日前市場(スポット市場)や実需給の1時間前まで調整的な取引ができる当日市場(時間前市場)などを開設している。
<1.1. About Japan Electric Power Exchange>
The Japan Electric Power Exchange (JEPX) is an exchange that mediates spot and forward transactions of electricity.
The Japan Electric Power Exchange is a day-ahead market where electricity is bought and sold for next-day delivery between businesses looking for buyers of physical electricity and businesses that want to procure electricity to meet their demand for electricity. The spot market) and the same-day market (early market) that allows for adjustment trading up to one hour before the actual supply and demand.

<1.1.1.一日前市場>
電力小売の全面自由化に伴い、2016年4月より計画値同時同量制度が導入された。
この計画値同時同量制度とは、発電量調整供給契約の契約者となる発電契約者の事前に策定した発電計画と発電契約者の実際の発電実績とを管理時間(例えば、30分)単位で一致させると共に、託送供給契約の契約者となる需要契約者の事前に策定した需要計画(電力需要計画)と需要契約者の実際の需要実績とを30分単位で一致させるという制度である。
さらに計画値同時同量制度では、発電計画および需要計画を受け取った一般送配電業者はこれらの計画値と当日の実績との差分の電力量(インバランス)を調整し、発電契約者または需要契約者はこの調整に係る対価(インバランス料金)を支払うことが求められている。
<1.1.1. Day-ahead Market>
Along with the full liberalization of the electricity retail market, a planned value simultaneous same amount system was introduced from April 2016.
This planned value simultaneous and equal amount system is a management time unit (for example, 30 minutes) between the power generation plan formulated in advance by the power generation contractor who is the contractor of the power generation adjustment supply contract and the actual power generation performance of the power generation contractor. In addition, it is a system that matches the demand plan (power demand plan) formulated in advance of the demand contractor who is the contractor of the wheeling supply contract with the actual demand record of the demand contractor in units of 30 minutes.
In addition, under the planned value simultaneous same amount system, general power transmission and distribution companies that receive the power generation plan and demand plan adjust the power amount (imbalance) of the difference between these planned values and the actual results of the day, and The customer is required to pay the consideration (imbalance fee) for this adjustment.

発電事業者による発電計画および小売電気事業者(発電事業者から電気を調達して家庭や企業に電気を販売する事業者)による需要計画は、長期計画から徐々にその粒度が細かくなり、1日前には翌日の各コマ(すなわち、30分)毎の発電計画および需要計画がそれぞれ確定する。
この1日前の計画を確定する際の最終調整の場が、一日前市場(スポット市場)である。
一日前市場では、発電事業者の入札および小売事業者の入札のすべてをまとめ、突合せを行い価格と量とで調整し、発電事業者の1日前の発電計画と小売電気事業者の1日前の需要計画とを一致させている。
Power generation plans by power producers and demand plans by retail power producers (businesses that procure electricity from power producers and sell it to households and businesses) gradually become finer-grained from the long-term plan, and one day in advance. A power generation plan and a demand plan for each frame (that is, 30 minutes) of the next day are determined in .
The day-ahead market (spot market) is the place for final adjustments when finalizing the one-day-ahead plan.
In the day-ahead market, all of the bids from power generators and retailers are collected, matched, and adjusted for price and quantity. Aligned with the demand plan.

この一日前市場では、1日を電力の計量単位(コマ単位。毎時0分~30分、30分~60分)で分割した48コマにおける電力を個々の商品として取引されている。
そして、一日前市場ではブラインド・シングルプライスオークション方式で約定価格や約定量が決定されている。
具体的には、以下のとおりである。
[1]他参加者の入札動向が開示されない状態(ブラインド)で入札が行われる。
[2]日本卸電力取引所は締め切り後にすべての入札を売買に分け合成し、需給カーブ(「売り」の量-価格線と「買い」の量-価格線)の交点で約定価格と量を決定する(交点が複数点ある場合、価格は交点のうち一番安い価格、量は交点のうち一番多い量を選択)。
[3]入札者は、入札した価格によらず決定された約定価格(シングルプライス)で売買する。すなわち、約定価格より低い価格で入札された売りは約定価格で売れ、約定価格より高い価格で入札された買いは約定価格で買える。
In this day-ahead market, power is traded as individual commodities in 48 frames obtained by dividing one day into power measurement units (frame units: 0 to 30 minutes, 30 to 60 minutes every hour).
In the day-ahead market, the contract price and quantity are determined by a blind single-price auction method.
Specifically, it is as follows.
[1] Bidding is conducted in a state where the bidding trends of other participants are not disclosed (blind).
[2] After the deadline, the Japan Electric Power Exchange divides all bids into sales and synthesizes them, and at the intersection of the supply and demand curve ("sale" volume - price line and "buy" volume - price line), the contract price and volume are calculated. Decide (if there are multiple points of intersection, select the lowest price among the points of intersection, and the largest amount among the points of intersection for the amount).
[3] A bidder trades at a fixed contract price (single price) regardless of the bid price. That is, a sell bid at a price lower than the contract price can be sold at the contract price, and a buy bid at a price higher than the contract price can be bought at the contract price.

なお、一日前市場における取引の約定の結果によっては、連系線(東京-中部エリア間の周波数変換設備など)に流せる電気の量の制約で計算を分けて行う必要が生じる。
例えば、日本全国の入札を合成して需要-供給曲線を描き、その交点を約定価格として売買を成立させた際、中部エリアから東京エリアに流す電力量が設備上流せる電力量を超える場合、東日本(北海道・東北・東京)の入札のみを合成して需要-供給曲線を描き、その交点を東日本の約定価格とし、西日本も同様に中部から九州エリアまでの入札を合成して需要-供給曲線を描き、その交点を西日本の約定価格とする(この処理を市場分断処理という)。
このような市場分断処理によって算出される約定価格をエリアプライスといい、売買はエリアプライスによって成立する。
なお、日本卸電力取引所におけるエリアプライスは、北海道・東北・東京(関東)・中部・北陸・関西・中国・四国・九州(沖縄除く)の9つのエリア毎に異なっているとなっている。
In addition, depending on the result of the contract in the day-ahead market, it may be necessary to separate the calculations due to restrictions on the amount of electricity that can flow through interconnection lines (such as frequency conversion equipment between Tokyo and the Chubu area).
For example, when a demand-supply curve is drawn by synthesizing bids from all over Japan and a trade is established with the contract price at the intersection point, if the amount of power flowing from the Chubu area to the Tokyo area exceeds the amount of power flowing upstream from the facility, East Japan (Hokkaido, Tohoku, Tokyo) to draw a demand-supply curve, the intersection of which is set as the contract price for eastern Japan, and similarly for western Japan, a demand-supply curve is drawn by synthesizing bids from the central to Kyushu areas. The crossing point is the contract price for West Japan (this process is called the market segmentation process).
The contract price calculated by such market segmentation processing is called an area price, and trading is established at the area price.
The area prices on the Japan Electric Power Exchange are different for each of the nine areas of Hokkaido, Tohoku, Tokyo (Kanto), Chubu, Hokuriku, Kansai, Chugoku, Shikoku, and Kyushu (excluding Okinawa).

<1.1.2.当日市場>
発電計画および需要計画は1日前の計画が最終的なものであるが、発電設備が故障したり天気予報が外れたりするなどがあると、発電計画および需要計画の変更は避けられない。
そこで、1日前計画策定後における発電計画および需要計画の調整の場が、当日市場(時間前市場)である。
<1.1.2. Same-day market>
The power generation plan and the demand plan are finalized one day in advance, but if the power generation equipment breaks down or the weather forecast is wrong, the power generation plan and the demand plan will inevitably change.
Therefore, the place for adjusting the power generation plan and the demand plan after formulating the one-day-ahead plan is the same-day market (early-hour market).

当日市場では、一日前市場と同様に、電力の計測単位(コマ単位。毎時0分~30分、30分~60分)毎に取引を行うが、一日前市場が1日分48コマを一斉に計算するのに対して、当日市場ではコマ単位の商品毎のザラ場取引となっている。 In the intra-day market, as in the day-ahead market, transactions are made in units of power measurement (frame units: 0-30 minutes, 30-60 minutes every hour), but the day-ahead market trades 48 frames for the day all at once. On the other hand, in the intra-day market, it is a Zara market trading for each product in frame units.

<1.2.電力広域的運営推進機関について>
電力広域的運営推進機関(OCCTO)は、電気事業者が営む電気事業に係る電気の需給の状況の監視及び電気事業者に対する電気の需給の状況が悪化した他の小売電気事業者、一般送配電事業者、配電事業者又は特定送配電事業者への電気の供給の指示等の業務を行うことにより、電気事業の遂行に当たっての広域的運営を推進する機関である。

<2.本発明のコンセプト>
次に、図1Aおよび図1Bに基づいて、本発明のコンセプトについて説明する。
図1Aは発電事業者を中心とした入出金の流れを示す図であり、図1Bは本発明のコンセプトに基づく入出金の流れを示す図である。
<2. Concept of the present invention>
Next, the concept of the present invention will be explained based on FIGS. 1A and 1B.
FIG. 1A is a diagram showing the flow of deposits and withdrawals centered on power generation companies, and FIG. 1B is a diagram showing the flow of deposits and withdrawals based on the concept of the present invention.

まず、図1Aに示すように、再生可能エネルギー発電設備を有する発電事業者Aには、JEPXの約定価格に基づく電力取引代金と、OCCTOから供給促進交付金と、発電事業者Aの再生可能エネルギー発電設備により発電された電力由来の環境価値である非FIT非化石証書の購入者である環境価値購入者Xから環境価値取引対価である環境価値購入者支払金額Cc[円]が入金される。 First, as shown in FIG. 1A, power generation company A, which has renewable energy power generation facilities, receives the power transaction fee based on the contract price of JEPX, the supply promotion subsidy from OCCTO, and the renewable energy of power generation company A. Environmental value purchaser X, who is the purchaser of the non-FIT non-fossil certificate, which is the environmental value derived from the electricity generated by the power generation facility, receives the environmental value purchaser payment amount Cc [yen] as the consideration for the transaction of environmental value.

ここで、本発明における重要な前提の一つは、「発電事業者Aは、毎月固定単価での収入を得るものとする」である。
この前提に依拠すると、発電事業者Aが得たい毎月の収入額の単価(以下、「希望売電単価」という。)をcfg[円/kWh]とし、JEPXのエリアプライスをj[円/kWh]とし、供給促進交付金の単価をp[円/kWh]とし、環境価値取引対価の単価(すなわち、環境価値購入者Xが発電事業者Aに支払う対価の単価であり、以下、その額「環境価値購入者支払単価」という。)をcfc[円/kWh]とすると、
cfg=j+p+cfc ・・・ (1)
という関係から環境価値購入者支払単価cfcは、
cfc=cfg-(j+p) ・・・ (2)
となる。
したがって、エリアプライスjが高くなると、環境価値購入者支払単価cfcがマイナスになる、すなわち、発電事業者Aが環境価値購入者Xに金銭を支払うこともある。
Here, one of the important premises of the present invention is that "the power generation company A shall obtain income at a fixed unit price every month".
Based on this premise, the unit price of the monthly income that power generation company A wants to obtain (hereinafter referred to as the “suggested electricity sales unit price”) is cfg [yen/kWh], and the area price of JEPX is j [yen/kWh]. ], the unit price of the supply promotion subsidy is p [yen/kWh], and the unit price of the environmental value transaction consideration (that is, the unit price of the consideration paid by the environmental value purchaser X to the power generation company A, which is hereinafter referred to as “ ) is cfc [yen/kWh],
cfg=j+p+cfc (1)
From this relationship, the environmental value purchaser payment unit price cfc is
cfc=cfg-(j+p) (2)
becomes.
Therefore, when the area price j increases, the environmental value purchaser's payment unit price cfc may become negative, that is, the power generation company A may pay the environmental value purchaser X money.

また、発電事業者Aは、必要に応じて、環境価値購入者支払金額Ccを算出する環境価値購入者支払金額算出業者に算出手数料f[円/kWh]を支払う。
この場合、環境価値購入者支払単価cfcは、
cfg=j+p+cfc-f ・・・ (3)
という関係から、
cfc=cfg-(j+p-f) ・・・ (4)
となる。
In addition, the power generation company A pays a calculation fee f [yen/kWh] to an environmental value purchaser payment amount calculator that calculates the environmental value purchaser payment amount Cc as necessary.
In this case, the environmental value purchaser payment unit price cfc is
cfg=j+p+cfc-f (3)
From the relationship
cfc=cfg-(j+p-f) (4)
becomes.

以上説明した状況では、発電事業者Aは環境価値購入者Xに非FIT非化石証書を販売したにもかかわらず、環境価値購入者Xに対して金銭を支払うこともある。
このような精算は、商慣習になじまないだけでなく、純額決済となり、デリバティブとして、経理処理も煩雑になる。
In the situation described above, even though the power generator A sold the non-FIT non-fossil certificate to the environmental value purchaser X, it may pay the environmental value purchaser X money.
Such settlement not only does not conform to commercial practices, but is a net settlement, and as a derivative, the accounting process becomes complicated.

そこで、本発明のコンセプトは、「発電事業者Aが環境価値購入者Xに支払う環境価値取引対価を一時金として分別管理する」である。
すなわち、本発明における「一時金」とは、環境価値の支払いのために用いられるものである。
そして、このコンセプトを実現するために、図1Bに示すように、「分別口座」という概念を導入した。
Therefore, the concept of the present invention is to "separately manage the environmental value transaction consideration paid by the power generator A to the environmental value purchaser X as a lump sum".
That is, the "lump sum" in the present invention is used for payment of environmental value.
In order to realize this concept, the concept of "separate account" was introduced as shown in FIG. 1B.

この「分別口座」は、環境価値購入者支払金額Ccを算出するための便宜的な仮想口座としてもよいし、金融機関で実際に開設された口座であってもよい。 This "discretionary account" may be a convenient virtual account for calculating the environmental value purchaser's payment amount Cc, or may be an account actually opened at a financial institution.

以下、「分別口座」という概念を導入して環境価値取引対価を算出する環境価値取引対価算出方法(本出願人は、この方法を含む包括的なスキームを「Green Purchase Agreement(通称:「GPA」)」と称している。)、およびこの環境価値取引対価算出方法を実施するための環境価値取引対価算出装置、環境価値取引対価算出プログラムについて詳細に説明する。 Hereinafter, an environmental value transaction consideration calculation method for calculating an environmental value transaction consideration by introducing the concept of a "separate account" (the present applicant calls a comprehensive scheme including this method a "Green Purchase Agreement" (commonly known as "GPA"). )”, and an environmental value transaction consideration calculation device and an environmental value transaction consideration calculation program for carrying out this environmental value transaction consideration calculation method will be described in detail.

The area of the area price obtained by the area price obtaining means 150 may be the entire area, or may be the area to which the renewable energy power generation facility α1 received by the installation location receiving means 120 belongs.

<5.3.環境価値購入者支払金額の算出>
OCCTO等により供給促進交付金の額P[円]が公表されると、本発明の実施例である環境価値取引対価算出方法により環境価値購入者支払金額Cc[円]が算出される。
すなわち、環境価値購入者支払金額Ccの算出は、定期的に(本実施例では、1ヶ月に1回)実施される。
<5.3. Calculation of Environmental Value Purchaser Payment Amount>
When the OCCTO or the like announces the amount P [yen] of the supply promotion subsidy, the environmental value purchaser payment amount Cc [yen] is calculated by the environmental value transaction consideration calculation method according to the embodiment of the present invention.
That is, the environmental value purchaser payment amount Cc is calculated periodically (in this embodiment, once a month).

環境価値購入者支払金額Ccの算出を行うには、図4Cに示すように、供給促進交付金額取得ステップS31、環境価値購入者支払金額算出ステップS32を実施する。 To calculate the environmental value purchaser payment amount Cc, as shown in FIG. 4C, a supply promotion grant amount acquisition step S31 and an environmental value purchaser payment amount calculation step S32 are performed.

供給促進交付金額取得ステップS31では、発電事業者Aと環境価値購入者Xとの間の環境価値取引を仲介する売電代行業者が、図6に示すように供給促進交付金額取得手段140にOCCTO等が発電事業者Aに通知した供給促進交付金のP[円]を入力する。
すなわち、供給促進交付金額取得ステップS31において、供給促進交付金額取得手段140は、供給促進交付金の額Pの入力を受け付ける。
換言すると、供給促進交付金額取得手段140への入力は、本実施例においては売電代行業者が行う。
なお、供給促進交付金は定期的に(例えば、1月に1回)OCCTO等により発電事業者Aに通知されるものであるから、供給促進交付金額取得手段140にはこの供給促進交付金の額が定期的に入力される。
In the supply promotion subsidy amount acquisition step S31, the power selling agency that mediates the environmental value transaction between the power generation company A and the environmental value purchaser X sends OCCTO to the supply promotion subsidy amount acquisition means 140 as shown in FIG. Enter P [yen] of the supply promotion subsidy notified to power generation company A by
That is, in the supply promotion subsidy amount obtaining step S31, the supply promotion subsidy amount obtaining means 140 receives an input of the amount P of the supply promotion subsidy.
In other words, the input to the supply promotion subsidy amount acquiring means 140 is performed by the electricity selling agent in this embodiment.
Since the supply promotion subsidy is periodically (for example, once a month) notified to the power generation business operator A by OCCTO, etc., the supply promotion subsidy amount acquisition means 140 does not receive the supply promotion subsidy. Amounts are entered periodically.

環境価値購入者支払金額算出ステップS32では、図6に示すように、環境価値購入者支払金額算出手段160が、売電単価受付手段110が受け付けた希望売電単価cfg[円/kWh]、供給促進交付金額取得手段140が受け付けた供給促進交付金の額P[円]、環境価値購入者支払金額Cc[円]を算出する環境価値購入者支払金額算出業者(本実施例では売電代行業者)が徴収する算出手数料f[円/kWh]、設置場所受付手段120が受け付けた設置場所におけるエリアプライスj[円/kWh]、分別口座で管理される一時金の額T[円]、発電量取得手段130の取得した発電量G[kWh]に基づいて、一時金の額T[円]および環境価値購入者支払金額Cc[円]を算出する。 In the environmental value purchaser payment amount calculation step S32, as shown in FIG. An environmental value purchaser payment amount calculator (in this embodiment, an electricity sales agency ) collected by ), the area price j [yen/kWh] at the installation location received by the installation location receiving means 120, the lump-sum amount T [yen] managed in the separate account, the amount of power generation Based on the amount of power generation G [kWh] acquired by the acquisition means 130, the lump sum amount T [yen] and the environmental value purchaser payment amount Cc [yen] are calculated.

環境価値購入者支払金額算出ステップS32の具体的なステップは、以下の通りである。 Specific steps of the environmental value purchaser payment amount calculation step S32 are as follows.

まず、以下の式(5)より月次エリアプライスjm[円/kWh]を算出する(ステップS321)。
なお、Σ(j×G)は各コマのエリアプライスと発電量とを乗じたものを環境価値購入者支払金額Ccの算出対象となる月の一ヶ月間における全日全コマ分足し合わせたものであり、ΣGは各コマの発電量を環境価値購入者支払金額Ccの算出対象となる月の一ヶ月間における全日全コマ分足し合わせたもの(すなわち、環境価値購入者支払金額Ccの算出対象となる月の総発電量)である。
jm=Σ(j×G)÷ΣG ・・・ (5)
また、供給促進交付金の額P[円]と供給促進交付金の単価p[円/kWh]とについては、次の式(6)が成り立つ。
P=p×ΣG ・・・ (6)
First, the monthly area price jm [yen/kWh] is calculated from the following formula (5) (step S321).
Σ(j×G) is obtained by multiplying the area price of each frame by the power generation amount, and summing the results for all frames for all days in the month for which the environmental value purchaser payment amount Cc is to be calculated. ΣG is the sum of the power generation amount of each frame for all the frames for all days in the month for which the environmental value purchaser payment amount Cc is calculated (that is, the environmental value purchaser payment amount Cc is calculated) is the total amount of power generation for each month).
jm=Σ(j×G)÷ΣG (5)
Further, the following formula (6) holds for the amount P [yen] of the supply promotion subsidy and the unit price p [yen/kWh] of the supply promotion subsidy.
P=p×ΣG (6)

そして、上記の式(4)より導出される以下の式(7)に基づき環境価値購入者支払金額Ccを算出するための環境価値購入者支払仮金額Cc1を算出する(ステップS322)。
すなわち、環境価値購入者支払仮金額Cc1は、
Cc1={cfg-(jm-f)}×ΣG-P ・・・ (7)
で算出される。
Then, the environmental value purchaser provisional payment amount Cc1 for calculating the environmental value purchaser payment amount Cc is calculated based on the following expression (7) derived from the above expression (4) (step S322).
That is, the provisional amount Cc1 to be paid by the environmental value purchaser is
Cc1={cfg-(jm-f)}×ΣG-P (7)
Calculated by

次に、この仮算出した環境価値購入者支払仮金額Cc1が、0円未満であるか否かを判定する(ステップS323)。 Next, it is determined whether or not the tentatively calculated environmental value purchaser payment amount Cc1 is less than 0 yen (step S323).

環境価値購入者支払仮金額Cc1が0円未満であった場合、すなわち、環境価値購入者Xが発電事業者Aに金銭を支払うのではなく、発電事業者Aが環境価値購入者Xに金銭を支払うことになってしまうため、分別口座に環境価値購入者支払仮金額Cc1を入金する。
すなわち、分別口座における一時金の額Tは、
T=T+(-Cc1) ・・・ (8)
に増え、発電事業者受取単価cfg[円/kWh]は、
cfg=jm+p-f+Cc1÷ΣG ・・・ (9)
となり、環境価値購入者支払金額Ccは0円となる(ステップS324)。
したがって、最終的に、発電事業者Aが環境価値購入者Xに金銭を支払うこともなければ、環境価値購入者Xが発電事業者Aに金銭を支払うこともなくなる。
When the environmental value purchaser provisional payment amount Cc1 is less than 0 yen, that is, instead of environmental value purchaser X paying money to power generation business A, power generation business A pays environmental value purchaser X money. Since the environmental value purchaser will have to pay, the provisional amount Cc1 to be paid by the environmental value purchaser is deposited into the separate account.
That is, the lump sum amount T in the separate account is
T=T+(-Cc1) (8)
, and the unit price cfg [yen/kWh] received by the power generation company is
cfg=jm+p−f+Cc1÷ΣG (9)
As a result, the environmental value purchaser payment amount Cc becomes 0 yen (step S324).
Therefore, in the end, the power generation company A will not pay the environmental value purchaser X, and the environmental value purchaser X will not pay the power generation company A any money.

そして、ステップSS324で算出された一時金の額Tを分別口座データベース100C1に記録する(ステップS325)。 Then, the lump-sum amount T calculated in step SS324 is recorded in the separate account database 100C1 (step S325).

環境価値購入者支払仮金額Cc1が0円以上であった場合、分別口座の一時金の額Tが0円であるか否かを判定する(ステップS326)。
なお、発電事業者受取単価cfg[円/kWh]は、環境価値購入者支払仮金額Cc1が0円以上であった場合でも式(9)で表せる。
If the environmental value purchaser provisional payment amount Cc1 is 0 yen or more, it is determined whether or not the lump-sum amount T of the separate account is 0 yen (step S326).
Note that the unit price cfg [yen/kWh] received by the power generation company can be expressed by Equation (9) even when the provisional amount Cc1 to be paid by the environmental value purchaser is 0 yen or more.

分別口座の一時金の額Tが0円である場合、環境価値購入者支払仮金額Cc1を分別口座に保管されている一時金で補填できないため、環境価値購入者支払金額Ccを、
Cc=Cc1 ・・・(10)
とし(ステップS327)、前述のステップS325へ進む。
If the amount T of the lump-sum payment in the separate account is 0 yen, the environmental value purchaser payment amount Cc cannot be compensated for by the lump-sum payment kept in the separate account, so the environmental value purchaser payment amount Cc is
Cc=Cc1 (10)
(step S327), and the process proceeds to step S325.

分別口座の一時金の額Tが0円ではない、すなわち、分別口座の一時金の額Tが0円より大きい場合、環境価値購入者支払仮金額Cc1の少なくとも一部を分別口座に保管されている一時金で補填できる。
すなわち、環境価値購入者支払仮金額Cc1は、環境価値購入者支払金額Ccと分別口座に保管されている一時金より補填する金額M[円]とにより、
Cc1=Cc+M ・・・(11)
となる。
そして、分別口座に保管されている一時金より補填する金額Mを算出するために、一時金の額Tが環境価値購入者支払仮金額Cc1以上であるか否かを判定する(ステップS328)。
If the amount T of the lump-sum payment in the separate account is not 0 yen, that is, if the amount T of the lump-sum payment in the separate account is greater than 0 yen, at least part of the provisional amount Cc1 paid by the environmental value purchaser is stored in the separate account. You can make up for it with a lump-sum payment.
In other words, the environmental value purchaser provisional payment amount Cc1 is calculated using the environmental value purchaser payment amount Cc and the amount M [yen] compensated from the lump sum money stored in the separate account.
Cc1=Cc+M (11)
becomes.
Then, in order to calculate the amount M to be compensated from the lump sum money stored in the separate account, it is determined whether or not the lump sum amount T is equal to or greater than the environmental value purchaser provisional payment amount Cc1 (step S328).

一時金の額Tが環境価値購入者支払仮金額Cc1以上である場合、環境価値購入者支払金額Cc1のすべてを一時金で充当できる。
すなわち、分別口座より補填する金額Mおよび環境価値購入者支払金額Ccは、
M=Cc1、Cc=0 ・・・(12)
となり、分別口座に保管されている一時金の額Tは、
T=T-M=T-Cc1 ・・・(13)
に減り(ステップS329)、前述のステップS325へ進む。
If the lump sum amount T is equal to or greater than the environmental value purchaser's provisional payment amount Cc1, the environmental value purchaser's payment amount Cc1 can be allotted as a lump sum.
That is, the amount M to be compensated from the separate account and the amount Cc paid by the environmental value purchaser are
M=Cc1, Cc=0 (12)
Then, the lump-sum amount T kept in the segregated account is
T=TM=T-Cc1 (13)
(step S329) and proceeds to step S325.

一時金の額Tが環境価値購入者支払仮金額Cc1未満である場合、環境価値購入者支払仮金額Cc1の一部のみを一時金の額Tで補填できる。
すなわち、分別口座に保管されている一時金より補填する金額MはTとなることから、環境価値購入者支払金額Ccは式(11)より、
Cc=Cc1-T ・・・(14)
となり、分別口座に保管されている一時金の額Tは0円になり(ステップS330)、前述のステップS325へ進む。
If the lump sum amount T is less than the environmental value purchaser temporary payment amount Cc1, only a part of the environmental value purchaser temporary payment amount Cc1 can be compensated with the lump sum amount T.
That is, since the amount M to be compensated from the lump-sum money stored in the separate account is T, the environmental value purchaser payment amount Cc is obtained from equation (11).
Cc=Cc1-T (14)
As a result, the lump sum amount T stored in the separate account becomes 0 yen (step S330), and the process proceeds to step S325.

<6. Summary>
The environmental value trading consideration calculation device 100 of this embodiment described above accepts an input of a fixed desired electricity sales unit price, which is the electricity sales unit price desired by the power generation business operator and is the power generation business receipt unit price received by the power generation business operator. Since the amount to be paid to the power generation company and the desired power sales price match with the provision of the power sales unit price reception means, the power generation company can reliably sell the power and environmental value at the desired power sales price. .
Then, the environmental value purchaser payment amount calculation means 160 calculates at least the suggested electricity sales unit price cfg received by the electricity sales unit price receiving means 110, the amount P of the supply promotion subsidy under the FIP system, and the installation location received by the installation location receiving means 120. The environmental value purchaser payment amount Cc is calculated based on the area price j at the location, the lump sum amount T for payment of the consideration for the environmental value transaction, and the power generation amount G acquired by the power generation amount acquiring means 130, and the lump sum payment amount Cc is calculated. By changing the amount T, the environmental value purchaser's payment amount Cc as the environmental value transaction consideration is calculated based on at least the suggested electricity sales unit price cfg, the area price j and the installation location, and the supply promotion subsidy amount P. Therefore, when the area price j becomes expensive, the amount Cc to be paid by the environmental value purchaser as consideration for the environmental value transaction is reduced, and the lump-sum amount T is increased. can use the increased lump-sum payment to reduce the environmental value purchaser's payment amount Cc as consideration for the environmental value transaction to a low amount.
Further, according to the environmental value transaction consideration calculation method of the present embodiment described above, the electricity sales unit price receiving means 110 is the electricity sales unit price desired by the power generation business operator and the power generation business unit price received by the power generation business operator. By providing the desired electricity sales unit price reception step S10 for receiving the input of the desired electricity sales unit price cfg of a fixed amount, the amount to be paid to the power generation company matches the desired electricity sales unit price cfg, so that the power generation company can reliably Electric power and environmental value can be sold at the electric power selling unit price cfg.
Then, the environmental value purchaser payment amount calculation means 160 calculates at least the desired electricity sales unit price cfg received by the electricity sales unit price receiving means in the desired electricity sales unit price receiving step S10, the amount P of the supply promotion subsidy under the FIP system, and the power generation facility Based on the area price j at the installation location accepted by the installation location acceptance means 120 in the installation location acceptance step S11, the lump-sum amount T for payment of the consideration for the environmental value transaction, and the power generation amount G acquired by the power generation amount acquisition means 130 , the environmental value purchaser payment amount calculation step S32 for calculating the environmental value purchaser payment amount Cc and changing the amount T of the lump-sum payment enables the environmental value purchaser payment amount Cc as the consideration for the environmental value transaction to be , is calculated based on at least the suggested electricity sales unit price cfg, the area price j, the installation location, and the amount P of the supply promotion subsidy. The amount Cc to be paid by the purchaser is reduced and the amount T of the lump sum is increased, and when the area price j becomes cheaper, the increased lump sum is cut down and appropriated to make the environmental value purchaser payment as consideration for the environmental value transaction. The amount of money Cc can be suppressed to a low amount.
Therefore, the environmental value transaction consideration calculation device 100, the environmental value transaction consideration calculation method, and the environmental value transaction consideration calculation program of the present embodiment enable the power generator to sell electric power and environmental value at a stable suggested power selling price cfg. At the same time, it is possible to suppress the fluctuation range of the environmental value transaction consideration paid by the environmental value purchaser to the power generator.

さらに、売電単価受付手段110が受け付けた希望売電単価cfg、供給促進交付金の額P、環境価値購入者支払金額Ccを算出するための算出手数料f、設置場所受付手段120が受け付けた設置場所におけるエリアプライスj、環境価値取引対価の支払いのための一時金の額T、発電量取得手段130の取得した発電量Gに基づいて環境価値購入者支払金額算出手段160の算出した環境価値購入者支払金額Ccが0円未満であった場合、環境価値購入者支払金額算出手段160が環境価値購入者支払金額Ccを0円とすると共に一時金の額Tを変化させることにより、希望売電単価cfg、エリアプライスj、算出手数料f、供給促進交付金の額Pなどが如何なる額であっても、環境価値購入者支払金額Cが0円未満にならないため、会計上複雑になる純額決済を回避することができる。
また、供給促進交付金を環境価値購入者支払金額Ccの算出に組み込むことで、FIP制度における参照価格と市場価格とが相殺されるため、環境価値購入者支払金額Ccが市場価格を参照していないこととなり、店頭商品デリバティブ取引を規制する商品先物取引法が適用外となる。
Furthermore, the desired electricity sales unit price cfg received by the electricity sales unit price receiving means 110, the supply promotion subsidy amount P, the calculation fee f for calculating the environmental value purchaser payment amount Cc, the installation location received by the installation location receiving means 120 Environmental value purchase calculated by the environmental value purchaser payment amount calculation means 160 based on the area price j at the location, the lump sum amount T for payment of the consideration for the environmental value transaction, and the power generation amount G acquired by the power generation amount acquisition means 130 If the environmental value purchaser payment amount Cc is less than 0 yen, the environmental value purchaser payment amount calculation means 160 sets the environmental value purchaser payment amount Cc to 0 yen and changes the amount T of the lump-sum payment. Regardless of the unit price cfg, area price j, calculation fee f, supply promotion subsidy amount P, etc., the environmental value purchaser payment amount C will not be less than 0 yen, so net settlement will be complicated in terms of accounting can be avoided.
In addition, by incorporating the supply promotion subsidy into the calculation of the environmental value purchaser payment amount Cc, the reference price in the FIP system and the market price are offset, so the environmental value purchaser payment amount Cc refers to the market price. As a result, the Commodity Futures Trading Act, which regulates over-the-counter commodity derivative trading, will not apply.
