[0009] (Power management device 10) FIG. 1 is a schematic block diagram showing a system configuration of a power management device 10 according to the present disclosure. The power management device 10 (output device) is communicatively connected to a plant P via a network 70. The network 70 may be a network using wireless communication or a network using wired communication. The network 70 may be configured using, for example, the Internet or a local area network (LAN). The network 70 may also be configured by combining a plurality of networks.

[0010] The power management device 10 performs processing related to an EMS (Energy Management System). An EMS is, for example, a system for managing the demand and supply of electric power in a specific plant P. By introducing an EMS, for example, the demand and supply of electric power can be optimized. As a result, it may be possible to reduce costs compared to not introducing an EMS. Introducing an EMS in a plant P means, for example, that the plant P is controlled by the EMS. Introducing an EMS in a plant P may also mean, for example, that the demand and supply of electric power in the plant P are controlled by the EMS.

[0011] Here, the plant P may be at least a part of a facility such as a water treatment facility, a production facility, a power generation facility, a storage facility, or a waste treatment facility. The plant P may secondarily generate power by utilizing energy generated within the plant P when the plant P fulfills its primary purpose. For example, if the plant P includes a waste treatment facility, the plant P may secondarily generate power by utilizing thermal energy generated when the plant P treats (e.g., incinerates) waste.

[0012] The plant P may be a single plant (one facility) or a group of plants (multiple facilities) that can supply power to each other. For example, if the plant P is a group of plants, the plant P may include, in addition to at least some of the facilities, a solar power generation facility, a storage battery, and an on-site cogeneration system. If the plant P is a group of plants, the distance between the multiple facilities is not limited, and the multiple facilities do not need to be located close to each other.

[0013] The power management device 10 may consider, for example, the cost reduction effect assuming the introduction of a storage battery. In this case, the power management device 10 may, for example, charge the storage battery with power during the day when the electricity price is low, and discharge the power stored in the storage battery during the night when the electricity price is high. The power discharged from the storage battery may be sold to the market or consumed in the plant P. The power management device 10 may consider, for example, the cost reduction effect assuming control of a waste disposal facility. In this case, the power management device 10 may, for example, reduce the amount of waste processed at the waste disposal facility during the daytime when electricity prices are low, thereby suppressing the amount of power generated by the waste disposal facility, while, for example, increasing the amount of waste processed at the waste disposal facility during the nighttime when electricity prices are high, thereby increasing the amount of power generated by the waste disposal facility. Note that the cost reduction effect achieved by such control is also effective for plants P that are capable of generating power, other than waste disposal facilities. For example, if the plant P is a power generation facility, the power generation facility may not be operated during the daytime, thereby setting the power generation amount to zero, and may be operated at the upper limit of its capacity at night, thereby setting the power generation amount to 100% of its capacity. For example, the power management apparatus 10 may consider the cost reduction effect based on the adjustment of the demand (e.g., air conditioning, etc.). For example, the power management apparatus 10 may level the demand, change the demand in accordance with the electricity price, or change the demand in accordance with the supply.

[0014] The power management apparatus 10 introduces an EMS into the plant P and functions as a control apparatus that controls the plant P using the EMS. For example, the power management apparatus 10, as the control apparatus, formulates a plan for controlling the power supply and reception of the plant P. For example, the power management apparatus 10, as the control apparatus, controls the power supply and reception of the plant P in accordance with the formulated plan. The power management apparatus 10 functions as an output device that outputs plant operation value information corresponding to the operation value of the plant P. For example, the power management apparatus 10, as an output device, calculates the value of the plant P in which an EMS has been introduced. For example, the power management apparatus 10 outputs information corresponding to the value. The power management apparatus 10 functions as a processing device that processes billing for the cost of introducing an EMS into the plant P. For example, the power management apparatus 10, as a processing device, calculates the cost of introducing an EMS into the plant P. For example, the power management apparatus 10 creates information for billing the customer for the cost.

[0015] The user of the power management apparatus 10 may be, for example, an EMS business operator or a customer of the business operator. The customer may be, for example, a corporation that owns the plant P or a corporation that manages the plant P. The user may be, for example, a construction company of the plant P that sells the plant P to the corporation.

[0016] 2 is a schematic block diagram showing a specific example of the functional configuration of the power management apparatus 10. The power management apparatus 10 is configured using an information device (information processing device) such as a smartphone, tablet, personal computer, dedicated device, or server device. The power management apparatus 10 includes a communication unit 11, an input unit 12, an output unit 13, a storage unit 14, and a control unit 15.

[0017] The communication unit 11 is a communication device. The communication unit 11 may be configured as, for example, a network interface. The communication unit 11 communicates data with other devices via a network in accordance with the control of the control unit 15. The communication unit 11 may be a device that performs wireless communication or a device that performs wired communication.

[0018] The input unit 12 is configured using existing input devices such as a keyboard, a pointing device (such as a mouse or tablet), buttons, or a touch panel. The input unit 12 is operated by a user when inputting user instructions to the power management apparatus 10. The input unit 12 may be an interface for connecting the input device to the power management apparatus 10. In this case, the input unit 12 inputs an input signal generated in the input device in response to a user input to the planning apparatus 20. The input unit 12 may be configured using a microphone and a voice recognition device. In this case, the input unit 12 acquires an acoustic signal generated by the user's speech, performs voice recognition on the words spoken by the user, and inputs character string information of the recognition result to the power management apparatus 10. The voice recognition process may be performed by the control unit 15. The input unit 12 may be configured in any way as long as it is capable of inputting user instructions to the power management apparatus 10.

[0019] The output unit 13 outputs information in a form that can be recognized by a user. The output unit 13 may be, for example, an image display device such as a liquid crystal display or an organic electroluminescence (EL) display. The output unit 13 may be an interface for connecting an image display device to the power management device 10. In this case, the output unit 13 generates a video signal for displaying image data and outputs the video signal to the image display device connected to the output unit 13. The output unit 13 may be a device for outputting audio such as a speaker. The output unit 13 may be an interface for connecting an audio output device such as a speaker or headphones to the power management device 10. In this case, the output unit 13 generates an audio signal for playing audio data and outputs the audio signal to the audio output device connected to the output unit 13. The output unit 13 may be, for example, a printer. The output unit 13 may be an interface for connecting a printer to the power management device 10. In this case, the output unit 13 generates a print signal for printing print data and outputs the print signal to the printer connected to the output unit 13. The output unit 13 may be configured as a touch panel integrated with the input unit 12.

[0020] The storage unit 14 is configured using a storage device such as a magnetic hard disk drive or a semiconductor storage device. The storage unit 14 stores data used by the control unit 15. The storage unit 14 stores data required when the control unit 15 performs processing. The storage unit 14 functions as a power supply information storage unit 141, a power price information storage unit 142, a CO2 emission price information storage unit 143, a power demand information storage unit 144, a plan information storage unit 145, and a performance information storage unit 146.

[0021] The power source information storage unit 141 stores power source information. The power source information is information related to power sources. The power source is, for example, a power generation facility. The power generation facility is, for example, a solar power generation facility, a waste disposal facility, a wind power generation facility, a storage battery, a cogeneration system, etc. FIG. 3 is a diagram showing a specific example of a power source information table stored in the power source information storage unit 141. The power source information table has a plurality of power source information records. The power source information record has values ​​for a power source identification number (No.), a power source name, power generation capacity, power generation cost, power storage capacity, rapid power storage capacity, and power storage capacity. The power source identification number (No.) is a unique identification number corresponding to each power source. The identification number is, for example, a number. When the identification number is a number, the identification number may indicate the priority of the power source. In this case, for example, a smaller value of the identification number may indicate a power source with a higher priority. The power source name is a unique name used for the power source corresponding to the power source identification number. The power generation capacity is information indicating the amount of power that the power source corresponding to the power source identification number can generate per unit time (if the power source is a storage battery, the power generation capacity may also be the amount of power that can be discharged per unit time (i.e., the discharge capacity)). The power generation cost is information indicating the cost required for the power source corresponding to the power source identification number to generate a unit amount of power. The power storage capacity and quick power storage capacity are information indicating the amount of power that the power source corresponding to the power source identification number can store per unit time. The difference between the power storage capacity and quick power storage capacity is that the quick power storage capacity increases the amount of power that can be stored per unit time at the expense of power source degradation. The power storage capacity is information indicating the maximum amount of power that can be stored in the power source corresponding to the power source identification number. The power storage capacity, quick power storage capacity, and power storage capacity may be 0 if the power source is not capable of storing power.

[0022] Here, the information that serves as the basis for calculating the power generation cost differs depending on the type of plant P. For example, if the power source is a waste treatment facility, the information that serves as the basis for the calculation may be information about the cost of a fuel. The fuel is required for incinerating (burning) the waste. For example, if the power source is a cogeneration system, the information that serves as the basis for the calculation may be information about the cost of fuel. Examples of such fuel include natural gas, oil, and LPG. The fuel is used for power generation in the cogeneration system. If the power source is a storage battery, the information that serves as the basis for the calculation may be information about the depreciation cost of the storage battery (for example, storage battery cost / useful life, etc.).

[0023] The power price information storage unit 142 stores power price information. The power price information is information related to power prices. The power price may be treated as not fluctuating over time periods, or may be treated as fluctuating over time periods. When the power price is treated as not fluctuating over time periods, the power price is a fixed price. In this case, the power price information storage unit 142 may store a constant value (fixed price) as the power price information. When the power price is treated as fluctuating over time periods, the power price is a fluctuating price. In this case, the power price information storage unit 142 may store the power price information table shown in FIG. 4. FIG. 4 is a diagram showing a specific example of the power price information table stored in the power price information storage unit 142. The power price information table has a plurality of power price information records. Each power price information record has values ​​for the period and the price. The price in one power price information record indicates the buying and selling price per unit amount of power for the period (unit period) in that power price information record. In addition, when the selling price and buying price of electricity are different, the electricity price information record may have values ​​corresponding to the selling price and the buying price, respectively, instead of the price. For example, the electricity price information may be a predicted price for each time in the electricity market. The electricity market is a market where electricity is traded, such as the Japan Electric Power Exchange (JEPX). The electricity market may be, for example, a spot market or a supply and demand adjustment market. The electricity price may take into account subsidies from the national or local government. When there are multiple electricity markets, the electricity price information record may have values ​​corresponding to the price in each market.

[0024] The CO2 emission price information storage unit 143 stores CO2 emission price information. The CO2 emission price information is information related to the CO2 emission price. The CO2 emission price is, for example, the cost required to emit a unit amount of CO2. The cost may include, for example, a fine imposed by the national or local government. The CO2 emission price may be a fixed price or a variable price. If the CO2 emission price is a variable price, the CO2 emission price information storage unit 143 may store a CO2 emission price information table. In this case, the CO2 emission price information table may have a structure similar to that of the electricity price information table.

[0025] The power demand information storage unit 144 stores power demand information. The power demand information is information related to the demand for power in a plant P. The plant P consumes power, for example, for air conditioning equipment in a warehouse owned by the plant P. FIG. 5 is a diagram showing a specific example of a power demand information table stored in the power demand information storage unit 144. The power demand information table has a plurality of power demand information records. Each power demand information record has values ​​for a period and a demand amount. The demand amount in one power demand information record indicates the demand for power required by the plant P for the period in that power demand information record. In the example shown in the figure, the period is, for example, a period obtained by dividing one year into 30-minute intervals. However, the period (unit period) is not limited to this and may be, for example, in units of one hour, one day, one month, ten minutes, or one minute. The demand amount in the power demand information record may be, for example, an actual value for any past year (for example, last year). The demand amount in the power demand information record may be, for example, an average value of actual values ​​over any number of past years. The demand amount in the power demand information record may be, for example, a result of a simulation using software. The demand amount in the power demand information record may be, for example, a result generated by artificial intelligence. The demand amount in the power demand information may be, for example, input by a user to the power management device 10 and acquired in the power demand information storage unit 144. The user who inputs the power demand information may be, for example, the operator of the plant P.

[0026] The plan information storage unit 145 stores plan information. The plan information is, for example, information about a plan created by the planning means 151 described below. The plan information is updated, for example, after the plan is created by the planning means 151. The plan information storage unit 145 may store information about a plan in the case where an EMS is not introduced (hereinafter also referred to as "plan information in the case where an EMS is not introduced") in addition to the plan information created by the planning means 151 (hereinafter also referred to as "plan information in the case where an EMS is not introduced"). The plan information in the case where an EMS is not introduced is, for example, plan information that is set in advance and not by the power management apparatus 10. The plan information in the case where an EMS is not introduced may be input, for example, from the input unit 12.

[0027] The performance information storage unit 146 stores performance information. The performance information is information relating to the performance of control performed by the control means 152, which will be described later. The performance information is updated, for example, after the control is performed by the control means 152.

[0028] The control unit 15 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). When the processor executes a program, the control unit 15 functions as a planning means 151, a control means 152, a calculation means 153, an output means 154, an output means 155, a notification means 156, a calculation means 157, a notification means 158, a cost calculation means 159, and a creation means 160. Note that all or part of the functions of the control unit 15 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, and a semiconductor storage device (e.g., a solid-state drive (SSD)), as well as storage devices such as a hard disk or semiconductor storage device built into a computer system. The above program may be transmitted via a telecommunications line.

[0029] The control unit 15 may execute, for example, an application installed in its own device (the power management apparatus 10). A specific example of such an application is an application provided to the power management apparatus 10 as a dedicated application for the power management system 100. Another specific example of such an application is a web browser application. Such an application may be pre-installed in the power management apparatus 10, or may be downloaded each time a determination process is executed. For example, when implemented as a web browser application, the power management apparatus 10 may download and execute the application from a device specified by a specific web server (for example, the web server itself or another server) in response to the power management apparatus 10 connecting to the web server. The control unit 15 operates according to the program of the application being executed.

[0030] The planning means 151 formulates a plan for the EMS to maximize an objective function that represents the operational value of the plant P, for example. The EMS has multiple operation modes. The multiple operation modes have different constraint conditions, which will be described later. The planning means 151 formulates a plan to maximize the objective function within a range that satisfies the constraint conditions in each operation mode of the EMS.

[0031] The objective function is, for example, a function that represents the operational value of a plant P converted into a monetary amount. If the plant is a group of plants, the objective function may represent the operational value of the entire group of plants. The objective function is, for example, expressed by the following equation (1).

[0032] A+BC (1) A, B, and C are as follows: A: Profits obtained from the operation of each power source during the planning period B: Profits obtained from buying and selling electricity on the market during the planning period (amount of electricity purchased and sold) C: Cost of CO2 emissions during the planning period (CO2 emission price)

[0033] Here, the planning period is not particularly limited and may be, for example, one year, one month, one week, or one day. The planning unit period may be longer than the above-mentioned unit period. The planning period may be input from the input unit 12 or may be stored in the storage unit 14, for example.

[0034] (A: Profits obtained from the operation of each power source during the planning period) The profit is calculated, for example, by multiplying the amount of power generated by each power source by the profit obtained per unit of power generation. The amount of power generated by each power source is, for example, a target variable. The profit obtained per unit of power generation is calculated, for example, by subtracting the power generation cost from the power price. When the power price is a variable price, the power price that is a factor in calculating the profit obtained per unit of power generation can be the power price corresponding to the period during which the power source generates power. The power price is calculated, for example, based on power price information. The profits earned from the operation of each power source during the planning period may be calculated for each power source (e.g., solar power generation facility, waste treatment facility, storage battery, etc.). For example, if the power source is a waste treatment facility, the profits may vary based on the amount or timing of waste treatment. For example, as mentioned above, profits may be increased by treating more waste at night when electricity prices are high.

[0035] (B: Profits earned from buying and selling electricity on the market during the planning period) The profit is calculated, for example, by subtracting the total amount of electricity purchased in each market from the total amount of electricity sold in each market. The electricity sales amount is calculated by multiplying the amount of electricity sold by the electricity price. If the electricity price is variable, the electricity price during the electricity selling period can be used as the electricity price, which is a factor in calculating the electricity sales amount. The electricity purchase amount can also be calculated in the same way as the electricity sales amount. The amount of electricity sold and the amount of electricity purchased are, for example, objective variables. The electricity price is calculated, for example, based on electricity price information. The profits obtained by buying and selling electricity in the market during the planning period may be calculated for each market (for example, for each spot market and balancing market).

[0036] (C: Costs required for CO2 emissions during the planning period) The above cost is calculated, for example, by multiplying the amount of CO2 emissions in the plant P by the CO2 emission price (the cost required to emit a unit amount of CO2). The CO2 emission amount is, for example, a target variable. The CO2 emission price is calculated, for example, based on CO2 emission price information.

[0037] The investment value may include factors other than those exemplified in A to C above. For example, the investment value may further include an imbalance cost. The imbalance cost may include, for example, at least a portion of the imbalance cost for the power selling plan (e.g., shortage imbalance, surplus imbalance) and the imbalance cost for the power purchasing plan (e.g., shortage imbalance, surplus imbalance). For example, the imbalance cost for the power selling plan is calculated by multiplying the difference between the amount of power sold in the power selling plan that has been notified to the market and the actual amount of power sold by the imbalance penalty amount per unit of power amount. The penalty amount may be stored, for example, in the storage unit 14. For example, the operational value may further include the price required to process industrial waste (slag) at a waste treatment facility. If the industrial waste is reusable, this price may increase the operational value. If the industrial waste is not reusable, this price may decrease the operational value.

[0038] The planning means 151 performs a simulation using, for example, the objective function according to the above-mentioned equation (1) and constraint conditions to be described later. In the simulation, for example, the following a to e are used as objective variables. a: Power generation amount of each power source in each unit period b: The amount of electricity generated by the power source in each unit period that is stored in the storage battery (amount of stored electricity) c: The amount of electricity consumed by plant P out of the electricity generated by the power source in each unit period (demand amount) d: The amount of electricity sold to each electricity market out of the electricity generated by the power source in each unit period (power sales amount) e: The amount of electricity purchased from each electricity market in each unit period The demand amount related to c may basically be set based on the power demand information. In this case, the demand amount related to c may be set by changing the power demand in the power demand information under predetermined conditions. Examples of the predetermined conditions include, when the demand amount set for each unit period is increased or decreased, the increase or decrease is reflected in other unit periods on the same day, without changing the total demand amount for the same day.

[0039] Here, the multiple operation modes of the EMS include, for example, the following operation modes A to C. A: Cost-benefit priority mode B: CO2 emission reduction mode C: Battery deterioration suppression mode

[0040] The constraints differ depending on the operation mode. However, the constraints common to all operation modes include, for example, the following basic conditions. Basic condition 1: In each unit period, the amount of electricity supplied will not fall below the amount of electricity demanded. Basic condition 2: In each unit period, the amount of electricity stored in a storable power source (for example, a storage battery) does not exceed its storage capacity.

[0041] (A: Cost-benefit priority mode) The cost-merit priority mode is a mode (operational value maximization mode) that maximizes the operational value of the plant P. In this mode, for example, the objective function (i.e., the operational value of the plant P) is maximized with only the basic conditions as constraints.

[0042] (I: CO2 emission reduction mode) The CO2 emission suppression mode is a mode that maximizes the operational value of plant P while suppressing CO2 emissions to a certain level. In this mode, for example, in addition to the basic conditions, the following additional conditions are added as constraints to maximize the objective function. Additional condition: Total CO2 emissions during the planning period must be below a certain value. The constant value may be input from the input unit 12 or may be stored in the storage unit 14, for example.

[0043] (C: Battery deterioration suppression mode) The battery degradation suppression mode is a mode that suppresses the degradation of the battery while maximizing the operational value of the plant P. In this mode, for example, in addition to the basic conditions, the following additional conditions are added as constraint conditions to maximize the objective function. Additional condition A: Energy storage using the rapid energy storage capacity of the battery will not be performed, and energy storage will be performed using the (normal) energy storage capacity. However, when using the rapid charging capability to store electricity in a storage battery, the storage battery is likely to become hot and deteriorate. Therefore, by charging the storage battery without using the rapid charging capability, deterioration of the storage battery can be suppressed. As an additional condition, the following additional condition B may be added in place of the above additional condition A (power storage using the rapid charging capability is not performed). Additional condition B: The cost of power generation when rapid storage capacity is used is higher than the cost of power generation when (normal) storage capacity is used. Under the above additional condition B, the rate of deterioration of the storage battery is reflected in the power generation cost.

[0044] The planning means 151 creates a plan using, for example, the objective function and constraint conditions described above. In this embodiment, the planning means 151 creates a plan based on at least one of power demand, solar power generation amount, waste disposal power generation amount, power generation amount from storage batteries, CO2 emission price, spot market power price, and supply and demand balancing market power price. Note that the method of creating a plan by the planning means 151 is not limited to the method described above. Here, the planning means 151 may update the plan information periodically (for example, at a fixed time every day) for the purpose of, for example, the control means 152 described later utilizing the plan information. In this case, the operation mode of the EMS to be planned by the planning means 151 may be set in advance, for example. The operation mode of the EMS may be input from, for example, the input unit 12. Furthermore, the planning means 151 may update the plan information in response to an input from the input unit 12 for the purpose of, for example, the calculation means 153 described later calculating a plant operation value. In this case, the planning means 151 may create plans for all operation modes of the EMS.

[0045] The plan information created by the planning means 151 in the above manner is stored, for example, in the plan information storage unit 145. The plan information is stored, for example, as a plan information table in the plan information storage unit 145. The plan information table includes a plurality of plan information records. A plan information record is expressed, for example, as a combination of one unit period and plan values ​​corresponding to the above-mentioned objective variables a to e in that unit period. In addition, the planning means 151 may store plant value information corresponding to the operational value of the plant P in the memory unit 14 when the planning information is stored in the planning information memory unit 145, for example, for the purpose of the output means 154 described later utilizing the planning information.

[0046] The control means 152 controls the plant P based on the planning information from the planning means 151. The control means 152 may, for example, read out the planning information from the planning information storage unit 145. After controlling the plant P, for example, the control means 152 updates the performance information stored in the performance information storage unit 146 based on the performance of controlling the plant P. The performance information is stored, for example, as a performance information table in the performance information storage unit 146. The performance information table includes a plurality of performance information records. The performance information record is expressed, for example, as a combination of one unit period and performance values ​​corresponding to the above-mentioned objective variables a to e in that unit period.

[0047] The calculation means 153 calculates the operation value of the plant P. The operation value is expressed by, for example, the objective function. The calculation means 153 calculates a first plant operation value and a second plant operation value as the operation values. The first plant operation value is the operation value of the plant P in which an EMS is introduced. The calculation means 153 may calculate the first plant operation value for each of a plurality of operation modes. The second plant operation value is the operation value of a plant in which an EMS is not introduced.

[0048] The calculation means 153 calculates an operation value based on a plan and an operation value based on actual results as the operation values ​​(first plant operation value and second plant operation value).

[0049] The calculation means 153 may calculate the first plant operation value based on the plan, for example, based on the objective function and the plan information at the time of EMS introduction stored in the plan information storage unit 145. In this case, the calculation means 153 can calculate the first plant operation value based on the plan, for example, by substituting the plan value in the plan information for the objective variable in the objective function. The calculation means 153 may calculate the first plant operational value based on the plan, for example, based on the operational value information stored in the storage unit when the plan means 151 formulated the plan. The calculation means 153 may calculate the first plant operation value based on the actual performance, for example, based on the objective function and performance information stored in the performance information storage unit 146. In this case, the calculation means 153 can calculate the first plant operation value based on the actual performance, for example, by substituting the performance value in the performance information for the objective variable in the objective function.

[0050] The calculation means 153 may calculate the second plant operation value based on the plan, for example, based on the objective function and the plan information for a system without an EMS that is stored in the plan information storage unit 145. In this case, the calculation means 153 can calculate the second plant operation value based on the plan, for example, by substituting the plan value in the plan information for the objective variable in the objective function.

[0051] FIG. 6 is a diagram showing an example of a user interface output by the output means 154, the output means 155, and the notification means 156.

[0052] As shown in FIG. 6 , the output means 154 outputs first plant performance value information corresponding to the first plant performance value. Here, the output of the first plant performance value information by the output means 154 may mean that the output means 154 displays the first plant performance value information on a display surface such as the screen of an image display device or the page of a printed material, or in an electronic file. In this embodiment, the output means 154 outputs first plant performance value information for each of a plurality of operation modes. However, the output means 154 does not need to output first plant performance value information for each of a plurality of operation modes. For example, if the EMS has only one operation mode, the output means 154 may output only one piece of first plant performance value information. Furthermore, for example, when the output means 154 receives input of an operation mode to be output from the input unit 12, the output means 154 may output the first plant performance value information for the operation mode for which the input was received.

[0053] The output means 154 outputs first plant operation value information corresponding to the first plant operation value calculated by the calculation means 153. Here, the calculation means 153 calculates the first plant operation value information using the objective function. The objective function includes the variables A to C. Therefore, in this embodiment, the information used by the output means 154 to output the first plant operational value information (for example, the information that serves as the basis for the power generation cost as described above) differs depending on the type of plant P. Therefore, for example, a user can more reliably grasp the operational value of a plant P into which an EMS has been introduced depending on the type of plant P. The output means 154 outputs the first plant operational value information based on at least one of the power demand, the amount of solar power generation, the amount of power generated by waste disposal, the amount of power generated by the storage battery, the CO2 emission price, the spot market power price, and the supply and demand adjustment market power price. Therefore, for example, the user can more reliably grasp the operational value of the plant P in which the EMS is installed. Furthermore, if the plant P includes a waste treatment facility, the output means 154 outputs the first plant operation value information based on the amount or timing of waste treatment adjusted by the EMS. Therefore, for example, the output means 154 can output the first plant operation value information appropriately according to the waste treatment adjusted by the EMS.

[0054] However, the information used by the output means 154 to output the first plant operation value information does not need to differ depending on the type of plant P. For example, the power generation cost may be the same regardless of the type of plant P. The output means 154 may also output the first plant operation value information without being based on at least one of the power demand, the amount of solar power generation, the amount of power generated by waste disposal, the amount of power generated by the storage battery, the CO2 emission price, the spot market power price, and the supply and demand adjustment market power price. For example, the first plant operation value information may be calculated and output by considering only the power generation perspective without considering the power demand. The first plant operation value information may also be calculated and output without considering the CO2 emission price. Furthermore, the first plant operation value information may be calculated and output without considering the spot market power price and the supply and demand adjustment market power price, for example, with the power price set as a fixed price. Furthermore, if the plant P includes a wind power generation facility, a cogeneration system, or the like as a power source, the first plant operation value information may be calculated and output based on the power generation amount of each of these facilities.

[0055] The output means 155 outputs second plant operation value information corresponding to the second plant operation value. Here, the output of the second plant operation value information by the output means 155 may be such that the output means 155 displays the second plant operation value information on a display surface such as the screen of an image display device or the paper surface of a printed matter, or on an electronic file.

[0056] The notification means 156 notifies the user of the first plant operation value information output by the output means 154 and the second plant operation value information output by the output means 155 in a manner that allows them to be compared. Here, the notification of the first plant operation value information and the second plant operation value information by the notification means 156 may be made by the notification means 156 displaying the first plant operation value information and the second plant operation value information on a display surface such as the screen of an image display device or the paper surface of a printed matter, or in an electronic file.

[0057] In the illustrated example, the output means 154, the output means 155, and the notification means 156 display the first plant operation value information and the second plant operation value information as a first table T1 in a first display area R1. The first table T1 includes one header row T1a and multiple record rows T1b.

[0058] The header row T1a is the first row in the first table T1. The header row T1a indicates the content indicated by the information in each cell (information cell T1d) in the record row T1b. In this embodiment, the headers in the header row T1a are: plant operation value, electricity trading amount, and CO2 emission price. The electricity trading amount corresponds to variable B in the above formula (1). The CO2 emission price corresponds to variable C in the above formula (1). The header row T1a is common to the first plant operation value information and the second plant operation value information.

[0059] Each record row T1b represents first plant operation value information or second plant operation value information. Of the multiple record rows T1b, the record row T1b closer to the header row T1a represents first plant operation value information, and the remaining record rows T1b represent second plant operation value information. Record row T1b includes a header cell T1c and an information cell T1d. Header cell T1c is the first cell of record row T1b. Header cell T1c indicates whether the corresponding record row T1b represents first plant operation value information or second plant operation value information (for example, whether an EMS has been introduced or not, and if an EMS has been introduced, which operating mode it is in, etc.).

[0060] When outputting the first plant operation value information for each of the plurality of operation modes, the output means 154 may highlight the first plant operation value information relating to a preferred operation mode. For example, the output means 154 may highlight the record row T1b relating to the preferred operation mode by coloring or changing the font. For example, the preferred operation mode may be determined by the output means 154 receiving an input of the operation mode from the input unit 12. For example, the preferred operation mode may be determined by the output means 154. In this case, the output means 154 may determine the preferred operation mode, for example, based on the first plant operation value in each mode. For example, the output means 154 may determine the other operation mode as preferred if the difference between the cost-merit priority mode and the other operation mode is within a predetermined threshold, and may determine the cost-merit priority mode as preferred if the difference is equal to or greater than the predetermined threshold. The predetermined threshold may be stored in the storage unit 14 or input from the input unit 12.

[0061] In this embodiment, the notification means 156 displays the first plant operation value information and the second plant operation value information in record row T1b in first table T1, respectively, so that the notification means 156 notifies the user of both pieces of information in a manner that allows them to be compared. However, the form of notification by the notification means 156 is not limited to this. For example, the notification means 156 may display the first plant operation value information and the second plant operation value information in a graph, so that the notification means 156 notifies the user of both pieces of information in a manner that allows them to be compared.

[0062] In this embodiment, the first display area R1 also displays (outputs) a prerequisite Pc1, which is a premise for calculating the investment value. In the illustrated example, a CO2 conversion coefficient is displayed as the prerequisite Pc1. The CO2 conversion coefficient is, for example, CO2 emission price information stored in the CO2 emission price storage unit. The CO2 conversion coefficient is, for example, the cost required to emit CO2 per unit amount. In the illustrated example, the prerequisite Pc1 is displayed below and to the right of the first table T1. However, the display position and display format of the prerequisite Pc1 are not limited to this.

[0063] Furthermore, when the precondition Pc1 is displayed on an image display device, for example, the precondition Pc1 displayed in the first display area R1 can be made operable by the input unit 12, and the control unit 15 may receive an input for changing the precondition Pc1 from the input unit 12. When the control unit 15 receives a change to the precondition Pc1, it may update the contents of the first table T1. In this case, the user can easily confirm to what extent the operational value of the plant P will change due to a change in the precondition Pc1. Furthermore, as the precondition Pc1, in addition to the CO2 conversion factor, other preconditions such as the power supply capacity and storage capacity of the power source may be displayed in the first display area R1. Furthermore, the precondition Pc1 does not have to be displayed in the first display area R1.

[0064] FIG. 7 is a diagram showing an example of a user interface output by the output means 154, the output means 155, the calculation means 157, and the notification means 158.

[0065] As shown in FIG. 7 , the calculation means 157 calculates the difference between the first plant performance value information output by the output means 154 and the second plant performance value information output by the output means 155. In this embodiment, the calculation means 157 calculates the difference between the first plant performance value in one operation mode among the first plant performance values ​​in a plurality of operation modes and the second plant performance value. Note that the calculation means 157 may employ, as the first plant performance value, a representative value (e.g., an average value or a median value) of the first plant performance values ​​in a plurality of operation modes. Furthermore, the calculation means 157 may accept input of the type of operation mode from the input unit 12 and employ, as the first plant performance value, the first plant performance value related to the input operation mode.

[0066] The notification means 158 notifies the user of the difference calculated by the calculation means 157 along with the cause of the difference. The cause includes an adjustment by an EMS to the timing of waste treatment at a waste treatment facility. Therefore, for example, the user can easily understand the difference in operational value between a plant P with an EMS and a plant P without an EMS, which is caused by the adjustment of the timing of waste treatment. Here, the notification means 158 may notify the user of the difference and the cause of the difference by displaying the difference and the cause of the difference on a display surface such as the screen of an image display device or the paper surface of a printed matter, or in an electronic file.

[0067] In the illustrated example, the output means 154, the output means 155, the calculation means 157, and the notification means 158 display the difference and the factors of the difference as a second table T2 in a second display area R2. The second table T2 includes one header row T2a and one record row T2b. Note that the first display area R1 shown in FIG. 6 and the second display area R2 shown in FIG. 7 may be displayed simultaneously at different positions on the same display surface (e.g., a screen or a piece of paper), or may be displayed at different times in the same area on the same display surface.

[0068] The header row T2a is the first row in the second table T2. The header row T2a indicates the content of the information in each cell (information cell T2d) in the record row T2b. In this embodiment, the headers in the header row T2a are: EMS introduction effect, solar power generation amount, waste disposal power generation amount, storage battery power generation amount, CO2 emission price, spot market electricity price, and supply and demand adjustment market electricity price. Of these items, the EMS introduction effect is the difference calculated by the calculation means 157, and the other items are the causes of the difference. Of the other items, the solar power generation amount, waste disposal power generation amount, and storage battery power generation amount correspond to variable A in the above formula (1) and indicate the profit obtained by operating each power source. Of the other items, the spot market electricity price and supply and demand adjustment market electricity price correspond to variable B in the above formula (1) and indicate the profit obtained by buying and selling electricity in each market. Of the other items, the CO2 emission price corresponds to variable C in the above formula (1). The header row T2a is common regardless of the operation mode to be notified.

[0069] Each record row T2b represents the difference between the first plant operation value and the second plant operation value and the cause of the difference. The record row T2b includes an information cell T2d. In this embodiment, the notification means 158 notifies the user of the difference and the cause of the difference by displaying the difference and the cause of the difference in record row T2b in second table T2. However, the manner in which the notification means 158 notifies the user of this information is not limited to this. For example, the notification means 158 may notify the user of the difference and the cause of the difference by displaying a graph.

[0070] In this embodiment, the second display area R2 also displays (indicates) a precondition Pc2 that is a premise for calculating the difference. In the illustrated example, information about the operation mode of the EMS, information about the spot market electricity price, and information about the balancing market electricity price are displayed as the preconditions Pc2. The information about the EMS operation mode indicates, for example, the operation mode that is a premise for calculating the difference and its factors. The information about the spot market electricity price indicates the spot market electricity price per unit time that is a premise for calculating the spot market electricity price, which is one of the factors for the difference. The information about the balancing market electricity price indicates the balancing market electricity price per unit time that is a premise for calculating the balancing market electricity price, which is one of the factors for the difference. In the illustrated example, the precondition Pc2 is displayed below and to the right of the second table T2. However, the display position and display format of the precondition Pc2 are not limited to this. In addition, as the precondition Pc2, other preconditions other than the information on the operation mode of the EMS, the information on the spot market electricity price, and the information on the supply and demand balancing market electricity price may be displayed in the second display area R2. Furthermore, the precondition Pc2 does not have to be displayed in the second display area R2.

[0071] As shown in FIG. 2, the cost calculation means 159 calculates billing costs based on the first plant operation value (hereinafter also referred to as the corresponding first plant operation value) corresponding to the first plant operation value information output by the output means 154. The cost calculation means 159 may calculate billing costs, for example, so that a business operator can make an estimate for a customer who is considering introducing an EMS. In this case, the corresponding first plant operation value may be calculated based on planning information. The cost calculation means 159 may calculate billing costs, for example, so that a business operator can bill a customer who has already introduced an EMS. In this case, the corresponding first plant operation value may be calculated based on planning information or actual performance information.

[0072] The cost calculation means 159 may calculate the claimed cost not only based on the corresponding first plant operation value but also based on, for example, the second plant operation value corresponding to the second plant operation value information output by the output means 155. For example, the cost calculation means 159 may calculate the claimed cost based on the difference calculated by the calculation means 157.

[0073] For example, the billed cost may be a part of the corresponding first plant operation value. In this case, when the corresponding first plant operation value has a different operation value between a first period and a second period, which are different periods, the billed cost may be a part of the first plant operation value corresponding to the first period and the first plant operation value corresponding to the second period, whichever has the lower operation value. In either of these cases, the billed cost may be, for example, an amount corresponding to the power purchase and sale price related to variable B in the above equation (1).

[0074] For example, the billed cost may be a part of the operation value corresponding to the difference calculated by the calculation means 157 (the difference between the first plant operation value information and the second plant value information).

[0075] For example, the billed expenses may be higher when the corresponding first plant operation value exceeds a predetermined standard than when the corresponding first plant operation value does not exceed the predetermined standard. In this case, the billed expenses differ depending on whether the first plant operation value exceeds the predetermined standard, and the expense calculation means can calculate the billed expenses, for example, as a so-called performance fee (success fee). In this case, for example, the predetermined standard, the billed expenses when the predetermined standard is exceeded, and the billed expenses when the predetermined standard is not exceeded may each be stored in the memory unit 14.

[0076] For example, the billed fee may be paid periodically over a predetermined period. In this case, the cost calculation means 159 can calculate the billed fee when a user uses the EMS on a subscription basis, for example. In this case, for example, the first plant operation value may be calculated based on the plan information, and the business operator may present the billed fee calculated by the cost calculation means 159 to a customer who is considering introducing the EMS. In this case, the billed fee may be calculated by multiplying the difference calculated by the calculation means 157 by a predetermined rate. The predetermined rate may be stored in the storage unit 14, for example.

[0077] The creation means 160 creates billing information for billing a customer. The creation means 160 may create the billing information based on, for example, the billing cost calculated by the cost calculation means 159. Note that, for example, the billing information may be information corresponding to the billing cost. For example, the billing information may be information simply indicating the billing cost. For example, the billing information may be information regarding an estimate or invoice that lists the billing cost (for example, information for creating an estimate or invoice, or information indicating an electronic file of the estimate or invoice). For example, the billing information may be information for electronically sending the billing cost to a customer. Note that the creation means 160 may display the billing information, for example, on a display surface such as the screen of an image display device or the paper surface of a printed material, or in an electronic file.

[0078] For example, the creation means 160 may create billing information for billing a part of the corresponding first plant operation value to a customer. In this case, for example, a business operator can reliably bill a part of the first plant operation value to a customer.

[0079] For example, the creation means 160 may create billing information for billing the customer for a portion of the corresponding first plant operation value, which is the lower of the first plant operation value corresponding to the first period and the first plant operation value corresponding to the second period. In this case, for example, the creation means can create conservative (safe) billing information that is highly acceptable to the customer.

[0080] For example, the creation means 160 may create billing information for billing the customer for a portion of the operational value corresponding to the difference calculated by the calculation means 157. In this case, for example, the business operator can reliably bill the customer for a portion of the operational value corresponding to the difference between the first plant operational value information and the second plant value information.

[0081] 8 is a diagram illustrating an outline of an example of the hardware configuration of an information processing device 90 applied to this embodiment. The information processing device 90 includes a processor 91, a main memory device 92, a communication interface 93, an auxiliary memory device 94, an input / output interface 95, and an internal bus 96. The processor 91, the main memory device 92, the communication interface 93, the auxiliary memory device 94, and the input / output interface 95 are communicably connected to each other via the internal bus 96. The information processing device 90 may be applied to, for example, a power management device 10. In this case, for example, the communication unit 11 may be configured using the communication interface 93. For example, the memory unit 14 may be configured using the auxiliary memory device 94. Furthermore, the control unit 15 may be configured using the processor 91 and the main memory device 92.

[0082] The operations of the above-mentioned control units are stored in the form of a program in an auxiliary storage device 94 (storage). The processor 91 reads the program from the auxiliary storage device 94, loads it into the main storage device 92, and executes the above-mentioned processes in accordance with the program. The processor 91 also allocates storage areas in the main storage device 92 corresponding to the above-mentioned storage units in accordance with the program. Examples of the processor 91 include a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and a microprocessor.

[0083] The program may be for realizing some of the functions to be performed by the information processing device 90. For example, the program may be combined with other programs already stored in the auxiliary storage device 94 or other programs implemented in other devices to perform the functions. In another example of the embodiment, the information processing device 90 may include a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device) in addition to or instead of the above configuration. Examples of PLDs include PAL (Programmable Array Logic), GAL (Generic Array Logic), CPLD (Complex Programmable Logic Device), and FPGA (Field Programmable Gate Array). In this case, some or all of the functions realized by the processor 91 may be realized by the integrated circuit. Such an integrated circuit is also included as an example of a processor.

[0084] Examples of the auxiliary storage device 94 include a magnetic disk, a magneto-optical disk, an optical disk, and a semiconductor memory. The auxiliary storage device 94 may be an internal medium directly connected to the bus of the information processing device 90, or an external medium connected to the information processing device 90 via the input / output interface 95 or a communication line. Furthermore, when this program is distributed to the information processing device 90 via a communication line, the information processing device 90 that has received the program may load the program into the main storage device 92 and execute the above-mentioned processing. In at least one embodiment, the auxiliary storage device 94 is a non-transitory tangible storage medium.

[0085] The program may also be a program for realizing some of the above-described functions. Furthermore, the program may be a so-called differential file (differential program) that realizes the above-described functions in combination with another program already stored in the auxiliary storage device 94.

[0086] The power management apparatus 10 may be implemented using a plurality of information processing devices. For example, the power management apparatus 10 may be implemented using a device such as a cloud. For example, in the power management apparatus 10, the storage unit 14 and the control unit 15 may each be implemented in a different information processing device. For example, the storage unit 14 of the power management apparatus 10 may be distributed and implemented in a plurality of information processing devices. The functions of the power management apparatus 10 as a control device, an output device, and a processing device may be distributed across a plurality of information processing devices.

[0087] (Power management method) An example of a power management method using the power management apparatus 10 will be described with reference to FIG. 9. FIG. 9 is a flowchart showing an example of a power management method using the power management apparatus 10. In this method, before introducing an EMS, a business operator encourages a customer to introduce an EMS. When encouraging the introduction, the power management apparatus 10 performs a process (output step) of outputting first plant operation value information. It can be said that the power management method includes an output method that includes the output step.

[0088] In this power management method, first, the planning means 151 formulates a plan (S101). Thereafter, the output means 154 outputs the first plant operation value information and the like (S102). At this time, the output means 154 may, for example, cooperate with the output means 155, the notification means 156, the calculation means 157, and the notification means 158 to display the user interface shown in Fig. 6 or 7. Thereafter, the cost calculation means 159 estimates the billing costs to be billed by the business to the customer (S103). At this time, the creation means 160 may display the billing information on a display surface such as the screen of an image display device or the paper surface of a printed matter, or in an electronic file, so that the user can recognize the billing costs. Note that the order of output by the output means 154 (S102) and the estimate by the cost calculation means 159 (S103) may be reversed.

[0089] If the customer does not agree to the introduction of the EMS (S104: No), the EMS is not introduced in the plant P, and the flow ends. On the other hand, if the customer agrees to the introduction of the EMS (S104: Yes), the EMS is introduced to the plant P, and the planning by the planning means 151 and the control by the control means 152 are implemented (S105). At this time, for example, the planning means 151 may update the plan, for example, every 30 minutes, and the control means 152 may review the plan and control the plant P every time the plan is updated. After the EMS is continuously operated and planning and control are performed for a predetermined period, the creation means 160 creates billing information, and the business operator bills the user for the costs (S106). The predetermined period may be, for example, a period (e.g., one year) longer than the period during which the planning means 151 updates the plan.

[0090] As described above, according to the power management device 10 of this embodiment, the output means 154 outputs the first plant operation value information as shown in Figures 6 and 7. This makes it easier for a user, for example, to understand the operation value of a plant in which an EMS has been introduced.

[0091] 6, the output means 154 outputs the first plant operational value information for each of a plurality of operation modes. Therefore, for example, the user can easily grasp the plant operational value for each operation mode of the EMS.

[0092] The notification means 156 notifies the user of the first plant operation value information and the second plant operation value information in a comparable manner, thereby enabling the user to easily grasp the degree of improvement in plant operation value due to the introduction of the EMS, for example.

[0093] 7, the calculation means 157 calculates the difference between the first plant operation value information and the second plant operation value information. Therefore, for example, the user can easily understand the difference in operation value between a plant in which an EMS is introduced and a plant in which an EMS is not introduced.

[0094] The notification means 158 notifies the user of the difference calculated by the calculation means 157 together with the cause of the difference. Therefore, for example, the user can easily understand the difference in operational value between a plant in which an EMS has been introduced and a plant in which an EMS has not been introduced, together with the cause of the difference.

[0095] The technical scope of the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure.

[0096] The cost calculation means 159 and creation means 160 do not have to be present. The power management apparatus 10 does not have to function as the processing device. The power management apparatus 10 does not have to calculate billing costs or create billing information. Even when creating billing information, the billing information may be created directly from the first plant operation value, for example. In this case, although the creation means 160 is present, the cost calculation means 159 does not have to be present.

[0097] The calculation means 157 and the notification means 158 may not be present. The control unit 15 may not calculate the difference between the first plant operation value information and the second plant operation value information, and may not display this difference together with the cause of the difference. Furthermore, the notification means 158 may simply display the difference, and may not display the cause of the difference.

[0098] There is no need to provide the output means 155 and the notification means 156. The control unit 15 does not need to notify the user of the first plant operation value information and the second plant operation value information in a comparable manner.

[0099] The planning means 151 and the control means 152 may not be present. The power management apparatus 10 may not function as the control device. In this case, the power management apparatus 10 may simply function as an output device.

[0100] The calculation means 153 may not be provided. The power management device 10 (output device) may output, notify, or report the first plant operation value information and second plant operation value information acquired from the outside, or the difference between the two pieces of operation value information.

[0101] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modified examples may be combined as appropriate.

[0102] (Addendum) The embodiment can be understood, for example, as follows.

[0103] <1> An output device according to one embodiment of the present disclosure is an output device that outputs plant operation value information corresponding to the operation value of a plant, and is characterized by having an output means that outputs first plant operation value information corresponding to a first plant operation value, which is the operation value of the plant in which an EMS has been introduced.

[0104] The output means outputs the first plant operational value information, which allows, for example, a user to easily grasp the operational value of a plant in which an EMS has been introduced.

[0105] <2> the above <1> In the output device according to the present invention, the EMS may have a plurality of operating modes, and the output means may output the first plant operation value information for each of the plurality of operating modes.

[0106] The output means outputs the first plant operation value information for each of the plurality of operation modes, thereby making it easier for a user, for example, to grasp the plant operation value for each operation mode of the EMS.

[0120] The output means outputs the first plant operational value information based on at least one of the power demand, the amount of solar power generation, the amount of power generated by waste disposal, the amount of power generated by the storage battery, the CO2 emission price, the spot market electricity price, and the supply and demand balancing market electricity price. Therefore, for example, a user can more reliably grasp the operational value of a plant that has an EMS installed.

[0121] <10> the above <1> ~ <9> In the output device according to any one of the above aspects, a configuration may be adopted in which the output device further comprises a creation means for creating billing information for billing a customer for a portion of the first plant operation value corresponding to the first plant operation value information output by the output means.

[0122] The creation means creates billing information for billing a part of the first plant operation value to a customer. Therefore, for example, a business operator can reliably bill a part of the first plant operation value to a customer.

[0123] <11> the above <1> ~ <9> In any one of the above embodiments, the output device may be configured to further include an output means for outputting second plant operation value information corresponding to a second plant operation value, which is the operation value of the plant in which the EMS has not been introduced, a calculation means for calculating the difference between the first plant operation value information output by the output means and the second plant operation value information output by the output means, and a creation means for creating billing information for billing a customer for a portion of the operation value corresponding to the difference calculated by the calculation means.

[0124] The creation means creates billing information for billing a customer for a portion of the operation value corresponding to the difference calculated by the calculation means (the difference between the first plant operation value information and the second plant value information). Therefore, for example, a business operator can reliably bill a customer for a portion of the operation value corresponding to the difference between the first plant operation value information and the second plant value information.

[0125] <12> the above <1> ~ <9> In the output device according to any one of the above aspects, a cost calculation means may be provided for calculating a billing cost based on the first plant operation value corresponding to the first plant operation value information output by the output means, and the billing cost may be higher when the corresponding first plant operation value exceeds a predetermined standard than when the corresponding first plant operation value does not exceed the predetermined standard.

[0126] The cost calculation means calculates the claimed cost based on the first plant operation value corresponding to the first plant operation value information output by the output means. Here, the claimed cost is higher when the corresponding first plant operation value exceeds a predetermined standard than when the corresponding first plant operation value does not exceed the predetermined standard. In this way, the claimed cost differs depending on whether the first plant operation value exceeds the predetermined standard, and the cost calculation means can calculate the claimed cost, for example, as a so-called performance fee (success fee).

[0127] <13> the above <1> ~ <9> In the output device according to any one of the above aspects, a configuration may be adopted in which the output device further comprises a cost calculation means for calculating a billing cost based on the first plant operation value corresponding to the first plant operation value information output by the output means, and the billing cost is paid periodically over a predetermined period of time.

[0128] The cost calculation means calculates the claimed cost based on the first plant operation value corresponding to the first plant operation value information output by the output means. Here, the claimed cost is paid periodically over a predetermined period, and the cost calculation means can calculate the claimed cost when a user uses the EMS on a subscription basis, for example.

[0129] <14> the above <1> ~ <9> In any one of the above embodiments, the output device may be configured to further include a creation means for creating billing information for billing a customer for a portion of the first plant operation value that has a lower operation value among the first plant operation value corresponding to the first plant operation value information output by the output means, the first plant operation value corresponding to the first period and the first plant operation value corresponding to the second period.

[0130] The creating means creates billing information for billing the customer for a portion of the first plant operation value that has a lower operation value out of the first plant operation value corresponding to the first period and the first plant operation value corresponding to the second period. Therefore, for example, the creating means can create conservative (safe) billing information that is highly acceptable to the customer.
